Texas Margin Tax vs Franchise Tax: What’s the Difference, Which One Applies, and Why People Mix Them Up
Margin tax and franchise tax are the same thing
The statutory name for the tax is the franchise tax. That’s what Texas Tax Code Chapter 171 calls it, what the Comptroller of Public Accounts uses on their forms, and what shows up on your filing confirmations. The colloquial name is margin tax, and it caught on because the tax base is called taxable margin. CPAs, lawyers, and business owners use both terms interchangeably, which creates the problem this post is trying to solve. There is no separate margin tax obligation that exists alongside the franchise tax. They’re one tax with two names.
The naming gets messier because Texas reformed the franchise tax substantially in 2008 under House Bill 3, which is when the margin-based computation replaced the old earned-surplus and capital-based formulas. People who’d been in business before 2008 sometimes still use the old terminology, and people who came along after 2008 picked up the new margin terminology. Both groups are talking about the same tax. The 2008 reform is sometimes called the “margin tax” because that’s when the margin-based computation was introduced, which adds another layer to the naming confusion.
The Comptroller’s website uses both terms, but franchise tax is the dominant one because that’s the legal name. When you file, you’re filing a franchise tax report. When you compute the bill, you’re computing taxable margin. When you talk to a colleague at a Houston networking event about your annual May 15 obligation, you might call it margin tax. It’s the same tax. There’s no version of this where you owe one and not the other.
Why the legal name is franchise tax
The franchise tax exists because Texas charges entities for the privilege of doing business in the state. That privilege charge is called a franchise tax, which is the standard term for entity-level privilege taxes across U.S. states. California has a franchise tax. Delaware has a franchise tax. Texas has a franchise tax. The name has nothing to do with franchise businesses like Subway or McDonald’s. It refers to the legal concept of a franchise, which is the right to operate as a business entity granted by the state.
Texas Tax Code Chapter 171 is titled “Franchise Tax,” and the entire chapter regulates one tax. There’s no separate Chapter 172 for margin tax. The tax applies to taxable entities, which are defined under §171.0002 as essentially every legal entity except sole proprietorships, certain general partnerships of natural persons, and some trusts and exempt organizations. The statute calls the tax franchise tax throughout, and the Comptroller’s official communications follow the statute’s language.
Where the franchise tax name causes confusion is when business owners assume it only applies to franchise businesses. We get questions every year from new Texas LLC owners who say something like, “I’m not a franchisee, so I don’t owe franchise tax, right?” That misunderstanding is everywhere. The tax applies to any taxable entity formed in or doing business in Texas, regardless of whether the business is a franchisor, a franchisee, or completely independent. The Subway store down the street pays franchise tax. So does the Austin software startup. So does the Houston law firm. The name is misleading but the rule is universal.
Why people call it the margin tax
The colloquial name margin tax comes from the tax base. The 2008 reform restructured the franchise tax to apply to taxable margin rather than to earned surplus or capital, which were the prior bases. Taxable margin is computed from total revenue with one of several deductions subtracted, and the result is the number that gets multiplied by the tax rate. So when CPAs say margin tax, they’re describing the mechanic of how the tax works (the base is margin) rather than naming a separate tax.
The margin-based computation has four possible deduction methods that you compare and choose the lowest from: 70% of total revenue (which is just a 30% standard deduction baked into the formula), total revenue minus cost of goods sold (Texas COGS as defined under §171.1012), total revenue minus compensation (capped at $400,000 per employee under §171.1013 for the 2024 report year), and total revenue minus $1 million (a flat amount available to EZ-eligible entities). You pick the method that produces the lowest taxable margin. The tax rate then applies to that margin.
The phrase “taxable margin” is statutory. It appears throughout Chapter 171 and is defined in §171.101. The phrase “margin tax” is not statutory. It’s just shorthand that practitioners and business owners use because typing “the franchise tax with a margin-based computation” gets tedious. The Comptroller uses margin terminology constantly in the instructions to Form 05-158, but the form itself is titled the Franchise Tax Long Form Report. The naming is genuinely inconsistent across the Comptroller’s own materials.
How taxable margin is computed
Computing taxable margin starts with total revenue, which is defined under §171.1011. Total revenue isn’t the same as federal gross receipts. You start from federal gross receipts and adjust with specific add-backs (interest, dividends, etc.) and exclusions (flow-through funds, certain bad debts, certain reimbursed expenses for healthcare providers, etc.). The result is total revenue for franchise tax purposes. That number is the starting point for the margin calculation.
From total revenue, you compute four candidate margin amounts and pick the lowest. Method one: 70% of total revenue. So if total revenue is $5,000,000, this method gives you $3,500,000 of margin. Method two: total revenue minus COGS as defined by §171.1012, which doesn’t include all federal COGS items. Method three: total revenue minus compensation as defined by §171.1013, which is W-2 wages plus certain benefits, capped at $400,000 per employee. Method four: total revenue minus $1,000,000, available only to entities with revenue under $20 million.
Once you have your taxable margin, you apportion it to Texas. Apportionment uses a single-factor gross receipts formula: Texas receipts divided by total receipts everywhere. If you only do business in Texas, the factor is 100%. If you do business in multiple states, the factor is less than 100% and your apportioned margin is smaller. Apportioned margin then gets multiplied by the tax rate (0.75% standard, 0.375% retail/wholesale) to produce the franchise tax bill. There are minor credits available, but for most small businesses the apportionment-times-rate step is where the calc ends.
Three deduction methods compared
The COGS deduction is the right answer for retailers, wholesalers, and manufacturers with significant inventory and cost of goods sold. Texas COGS under §171.1012 is narrower than federal COGS in some ways and broader in others. It includes the cost of acquiring or producing goods sold, certain handling and storage costs, and certain labor costs allocable to production. It excludes some indirect costs that federal COGS would include, and the differences are detailed enough that we keep a separate Texas COGS worksheet for every wholesale and manufacturing client. A Houston food distributor with $8M in revenue and $5.5M in Texas COGS computes margin under this method at $2.5M, which usually beats the 70% method ($5.6M of margin) and the comp method ($7.2M of margin assuming $800K in payroll).
The compensation deduction is the right answer for service businesses with significant payroll. The compensation definition under §171.1013 is W-2 wages plus benefits like health insurance and retirement contributions, capped at $400,000 per employee for the 2024 report year (the cap is adjusted periodically). For a 12-person Austin marketing agency with $5M in revenue and $3.5M in payroll and benefits, the comp method gives you $1.5M of margin, which usually beats the 70% method ($3.5M of margin) and crushes the COGS method (zero COGS = $5M of margin). The cap matters when you have highly paid executives or owners; comp above $400K per person doesn’t reduce margin further.
The 70% method is the default when you don’t have substantial COGS or compensation. It’s also the floor. If your COGS deduction or compensation deduction produces a margin higher than 70% of revenue, you ignore that method and use the 70% margin instead. The 70% method is also called the standard deduction equivalent because it effectively gives every business a 30% deduction from revenue. For a $5M consulting firm with two employees and minimal payroll, the 70% method might give the lowest margin at $3.5M and become the right choice. The $1M flat deduction (method four) only applies to EZ-eligible entities and is an alternative to the EZ Computation, not to the Long Form.
EZ computation skips the margin calc entirely
The EZ Computation on Form 05-169 is an alternative to the margin calculation. Instead of computing margin and applying the 0.75% rate, you take apportioned total revenue and apply a flat 0.331% rate. There are no deductions for COGS or compensation. It’s available to entities with annualized total revenue under $20 million. The trade-off is simplicity versus potential savings: the EZ rate is lower than the standard 0.75% Long Form rate, but the base is total revenue rather than margin.
EZ usually wins for service businesses with high revenue and relatively low payroll. A solo consulting LLC with $1.5M of revenue, $200K in owner W-2 comp, and no COGS computes Long Form margin at $1.05M (the 70% method) for a $7,875 bill. EZ on the same business: $1.5M times 0.331% equals $4,965. EZ saves $2,910. Why? Because the standard 30% deduction built into the 70% method isn’t enough to overcome the higher 0.75% rate. The EZ rate of 0.331% is roughly equivalent to applying the 0.75% rate to a 56%-of-revenue margin, so EZ becomes the better choice when your deductions are less than 56% of revenue (or 12% for retail/wholesale entities subject to the 0.375% rate).
EZ loses for businesses with heavy deductions. The marketing agency example with $5M revenue and $3.5M in payroll computes Long Form margin at $1.5M and owes $11,250. EZ on the same firm: $5M times 0.331% equals $16,550. The Long Form saves $5,300. The crossover point depends on the rate that applies to your business. For retail/wholesale at 0.375%, EZ is rarely the right answer because the Long Form rate is half the standard rate. We run both calcs every year for every Texas business client and pick the cheaper one. The savings compound over decades.
Why the naming confusion costs people money
Business owners who don’t know that margin tax and franchise tax are the same thing make two recurring mistakes. The first is searching for advice using one term and missing relevant content under the other. We’ve had clients tell us they couldn’t find anything on margin tax planning, when there’s a sea of franchise tax content online; they just weren’t searching with the right word. The second mistake is more expensive: assuming they owe both. We’ve actually had new Texas business owners ask us about “the margin tax separate from the franchise tax,” thinking they had two bills coming. They don’t. It’s one tax.
The naming confusion also makes it harder to challenge or appeal a notice. Comptroller notices use the legal name (franchise tax) and the legal cite (Chapter 171). If you’ve been thinking of it as margin tax and you get a notice that says franchise tax assessment, you might assume it’s a different obligation and ignore it, which compounds the problem. The notice is for the tax you owe; the name on the notice is just the legal name. Treat any Comptroller notice referring to either franchise tax or margin tax as referring to the same obligation.
Software is part of the problem. Some tax software products and online filing services use “margin tax” in their interfaces while the Comptroller uses “franchise tax.” Some accountants use the terms interchangeably without explaining they’re the same. The result is that small business owners end up with a vocabulary problem that masks an obligation problem. Once you know they’re the same, the planning gets a lot easier because you can read any source confidently and translate between the terms in your head.

Frequently Asked Questions
Is the Texas margin tax the same thing as the franchise tax?
Yes, they’re the same tax. The franchise tax is the legal name under Texas Tax Code Chapter 171. The margin tax is the colloquial name that practitioners use because the tax base is called taxable margin. There is no separate margin tax obligation in Texas. If you owe one, you owe the other, because they’re identical. The Comptroller of Public Accounts administers the franchise tax, and any reference to margin tax in everyday conversation, in CPA blogs, or in informal communications means the same thing as franchise tax.
The naming convention traces back to 2008, when Texas reformed the franchise tax under House Bill 3 to use a margin-based computation instead of the prior earned-surplus and capital-based methods. People who’d been doing business in Texas before 2008 sometimes still distinguish between the “old franchise tax” and the “new margin tax,” but those are historical references to the pre- and post-reform versions of the same tax. The current tax is the post-2008 version, and it’s the same whether you call it franchise tax or margin tax.
The statutory language uses franchise tax throughout. Chapter 171 is titled “Franchise Tax.” Form 05-158 is titled the Franchise Tax Long Form Report. The Comptroller’s website organizes the tax under the franchise tax heading. So while practitioners and business owners use margin tax casually, the legal and administrative documents use franchise tax. When you get a notice from the Comptroller, it’ll say franchise tax. When you file a return, you’re filing a franchise tax return. Same tax.
Why the dual naming matters in practice: searching for guidance online produces different results depending on which term you use, and a business owner who only searches one term will miss half the content. A new LLC owner Googling “how to file Texas margin tax” will find different articles than one Googling “how to file Texas franchise tax,” even though the question is identical. CPAs and tax professionals tend to use franchise tax in formal writing and margin tax in conversation, which creates a vocabulary gap that confuses owners.
We’ve had Austin clients call us thinking they owed two separate Texas business taxes because their software product references margin tax and their formation documents reference franchise tax. We explain it’s one tax, walk them through the May 15 filing requirement, and they’re relieved to learn they’re not double-paying anything. The clarification takes five minutes and saves them weeks of low-grade anxiety about a phantom second tax bill.
Common mistakes related to the naming: assuming the franchise tax only applies to franchise businesses (it doesn’t; it applies to all taxable entities), assuming the margin tax is an income tax (it’s not; Texas has no income tax, and the franchise tax is computed on margin, not income), and assuming you can avoid one by paying the other (you can’t; they’re the same obligation). Each of those misunderstandings shows up in different ways in our intake conversations with new Texas business clients.
Documentation: when you file, you’re filing under the franchise tax name regardless of which colloquial term you use to think about it. Your Webfile confirmation, your filed Form 05-158 or 05-169, and any payment confirmations will reference franchise tax. Keep all of those documents together in a single business tax file with your federal returns. If a future preparer or auditor asks about your Texas filings, they’ll look for franchise tax records.
Real-world example: a Houston tech startup founder came to us in 2024 after his prior accountant left the firm. He was convinced the new accountant they assigned him had told him he owed both franchise tax and margin tax. We pulled his prior-year Webfile filings, walked him through the single annual filing, and showed him that he’d been paying the same tax every year under the franchise tax line. The confusion came from a casual remark his prior accountant had made about “the margin tax this year” that the founder interpreted as a separate obligation. One conversation, one cleared-up misunderstanding.
Audit considerations: the Comptroller audits franchise tax filings. There’s no separate audit channel for margin tax because there’s no separate margin tax. The four-year audit window under Tax Code §111.0042 applies to franchise tax assessments. If you’ve been filing correctly under the franchise tax line, you’re fine regardless of which term you use to describe it.
Where we add value at The Reed Corporation is cutting through the naming confusion early in the engagement so clients understand what they actually owe and what’s required. New Texas business clients get a five-minute orientation on franchise tax that covers the threshold, the filing date, the forms, and the naming. After that, they don’t have to worry about whether margin tax is a separate obligation. We file once, file on time, and the entity stays in good standing.
How is ‘taxable margin’ calculated for a Texas business?
Taxable margin is computed by taking total revenue and subtracting one of four deductions, then choosing the lowest of the four resulting margin amounts. The four candidate margins are: 70% of total revenue (which is equivalent to a 30% standard deduction), total revenue minus cost of goods sold as defined under Tax Code §171.1012, total revenue minus compensation as defined under §171.1013, and total revenue minus $1 million (only available to entities with revenue under $20 million). You pick the smallest of those four numbers as your taxable margin, then apportion it to Texas and apply the rate.
Total revenue is the starting point and it’s defined narrowly under §171.1011. It begins with federal gross receipts or sales but adds back items like interest income, dividends received, and certain other receipts that don’t show up in your federal gross income line. It subtracts items like flow-through funds (money collected on behalf of someone else, including sales tax), certain bad debts, and certain reimbursed expenses for healthcare providers. The result is total revenue for Texas franchise tax purposes, which is almost never identical to any number on your federal return.
The 70% method is the easiest to compute because it’s just total revenue times 0.70. If total revenue is $5M, the 70% method margin is $3.5M. This method effectively builds in a 30% standard deduction for every business and is the right answer when none of the other deductions produces a smaller margin. It’s particularly common for asset-light service businesses where the owner is the only person on payroll and there’s no inventory.
The COGS method is total revenue minus Texas COGS. The catch is that Texas COGS isn’t federal COGS. Texas defines COGS specifically under §171.1012 to include direct production costs, certain handling and storage, and certain labor allocable to production. It excludes some indirect costs and overhead that federal COGS would include. A Houston wholesale food distributor with $8M in revenue and $5.5M in Texas COGS computes COGS-method margin at $2.5M, versus the 70% method margin of $5.6M. COGS wins by a wide margin (no pun intended).
The compensation method is total revenue minus compensation as defined under §171.1013. Compensation includes W-2 wages, certain employee benefits like health insurance and retirement contributions, and is capped at $400,000 per employee for the 2024 report year. The cap is adjusted periodically. For a 12-person Austin marketing agency with $5M in revenue and $3.5M in qualifying compensation, the comp method margin is $1.5M. That beats the 70% method ($3.5M) substantially and is the right choice for most service businesses with significant payroll.
The $1M flat deduction method is only available to entities with total revenue under $20M, and it’s typically used by entities that don’t qualify for or don’t benefit from COGS or compensation deductions. For a $1.5M revenue solo consultancy with $200K in owner W-2 wages and no COGS, the $1M flat deduction gives a margin of $500K, which beats the 70% method ($1.05M margin), the COGS method ($1.5M margin since COGS is zero), and the comp method ($1.3M margin). The $1M deduction is generous when your other deductions are small.
Real-world example: an Austin SaaS startup with $4M in revenue, $1.2M in employee compensation, and zero COGS computes four candidate margins. 70% method: $2.8M. COGS method: $4M (no COGS). Compensation method: $2.8M. $1M flat deduction: $3M. The lowest is $2.8M (the 70% method or the comp method, both produce the same number in this case). At the standard 0.75% rate, the tax bill on $2.8M of margin (after apportionment, assuming 100% Texas) is $21,000. Compare that to the same firm running the EZ Computation: $4M times 0.331% equals $13,240. EZ wins here by about $7,760.
Common mistakes: using federal COGS instead of Texas COGS, including non-W-2 contractor payments in the compensation deduction (contractor 1099 payments don’t count as compensation; W-2 wages do), forgetting the per-employee compensation cap, and using full $1M deduction when revenue is over the $20M EZ eligibility limit. Each of those errors changes the margin computation and can result in an underpayment or overpayment that needs correcting on an amended return.
Documentation for taxable margin: you need supporting schedules for whichever deduction method you used. For COGS, that means a reconciliation from federal COGS to Texas COGS with adjustments documented. For compensation, that means a W-2 wage schedule with per-employee detail and benefit additions. For the 70% method or $1M flat method, the documentation is lighter but you still need to be able to show how total revenue was computed. The Comptroller can audit any of these computations within four years, and the COGS computation is the most-audited line.
Where we add value at The Reed Corporation is running the four-margin comparison every year, picking the right deduction method, and maintaining the supporting documentation so the answer holds up if audited. Most clients we take over from prior preparers were using the same deduction method every year by habit rather than choosing it based on the math. Switching methods based on current-year facts often produces a smaller tax bill. The Long Form is more work than the EZ, but the work usually pays for itself many times over.
Which deduction method gives Texas businesses the lowest margin tax: COGS, compensation, or the 30% standard?
The right answer depends on your business mix. There’s no single deduction method that wins for everyone, which is why running all four computations every year is the only way to know. As a general rule: retailers, wholesalers, and manufacturers benefit from the COGS deduction; professional service firms with significant payroll benefit from the compensation deduction; asset-light service businesses with minimal payroll often default to the 70% method; and small entities with low margins overall sometimes get the best result from the $1M flat deduction (if revenue is under $20M).
The COGS deduction wins when COGS exceeds 30% of revenue, because the 70% method margin is effectively a 30%-deduction baseline. A Houston wholesale distributor with $8M in revenue, $5.5M in COGS, and $500K in payroll computes margin candidates at $5.6M (70% method), $2.5M (COGS method), $7.5M (comp method), and $7M ($1M flat). COGS wins decisively. Even better, retailers and wholesalers get the 0.375% rate instead of the standard 0.75% rate, which doubles the savings impact of any deduction.
The compensation deduction wins when wages and benefits exceed 30% of revenue and you’re not retail/wholesale (because at 0.375%, the COGS deduction usually dominates for goods-based businesses). A 12-person Austin marketing agency with $5M in revenue and $3.5M in qualifying compensation computes margin candidates at $3.5M (70% method), $5M (COGS method, zero COGS), $1.5M (comp method), and $4M ($1M flat). Comp wins by a wide margin. Most professional services firms (consulting, law, accounting, marketing, design, engineering) fall into this pattern.
The 70% method wins by default when nothing else produces a smaller margin. A solo Houston consultancy with $1.5M in revenue, $150K in owner W-2 wages, and zero COGS computes margin candidates at $1.05M (70% method), $1.5M (COGS), $1.35M (comp), and $500K ($1M flat). The $1M flat method wins here, but if revenue were $25M instead of $1.5M, the $1M flat wouldn’t be available and the 70% method would win at $17.5M of margin. The 70% method also wins for businesses where both COGS and compensation are small relative to revenue, which is common for licensing, royalty, and investment-management entities.
Real-world example with dollar amounts: an Austin general contractor with $6M in revenue, $2.5M in subcontractor costs (which qualify as Texas COGS under specific rules in §171.1012), and $1.8M in W-2 compensation computes margin candidates at $4.2M (70% method), $3.5M (COGS method), $4.2M (comp method), and $5M ($1M flat). COGS wins at $3.5M of margin. At 0.75% (general contractors don’t get the 0.375% retail/wholesale rate), the tax bill is $26,250. Compare to the same business using only the 70% method out of habit: $4.2M times 0.75% equals $31,500. The COGS choice saves $5,250 a year.
Common mistakes: defaulting to the same method every year without re-running the comparison, including non-qualifying expenses in the COGS or comp deduction, forgetting the $400K per-employee compensation cap, and ignoring the EZ Computation as an alternative to the Long Form. Each of those mistakes inflates the tax bill by a real amount, especially for businesses that have been on autopilot with the same preparer for years.
The EZ Computation is the fifth option that isn’t part of the four-margin comparison. EZ skips the margin calculation entirely and applies 0.331% to total revenue. It’s available to entities with revenue under $20M and is sometimes cheaper than the Long Form, especially for service businesses with revenue in the $1M to $5M range and modest deductions. The EZ-vs-Long-Form comparison is separate from the four-deduction comparison and should be done as a final check before filing.
Documentation for whichever method you choose: the COGS method needs a Texas COGS computation that reconciles to federal COGS with documented adjustments. The compensation method needs a per-employee wage and benefit schedule with the $400K cap applied. The 70% method needs the total revenue computation and supporting reconciliation to federal gross receipts. The $1M flat method needs documentation that the entity qualifies (revenue under $20M annualized). All four methods need apportionment factor documentation if the business operates in multiple states.
Audit considerations: the COGS deduction draws the most audit attention because it’s the most complex and the most often misapplied. Auditors will ask for inventory rollforwards, vendor invoices, and a reconciliation from federal COGS to Texas COGS. The compensation deduction gets audited for the per-employee cap and for whether contractor payments were improperly included. The 70% method is rarely audited because it’s mechanical. The $1M flat method is audited for entity eligibility (revenue under $20M).
Where we add value at The Reed Corporation is the four-margin comparison plus the EZ check, run every year, with documentation maintained for whichever method we file under. For a typical service business client with $3M to $15M in revenue, the comparison takes about an hour and frequently produces savings in the $3,000 to $25,000 range compared to a one-method-fits-all approach. We’ve taken over engagements where the prior preparer had been using the COGS method on a service business with no inventory, simply because that’s how the prior year’s return was done. Switching to the comp method on the first return we prepared saved the client about $11,000.
When can a Texas business use the EZ computation (Form 05-169) instead of calculating margin?
The EZ Computation on Form 05-169 is available to any taxable entity with annualized total revenue of $20 million or less. That’s the only eligibility test. There are no industry restrictions, no entity-type restrictions, and no rules about prior-year filings. If your annualized total revenue is at or under $20M, you can elect EZ in any year you choose. You can switch back to the Long Form in subsequent years without penalty. The election is made by filing the EZ form for that report year.
The trade-off is simplicity versus potential savings. EZ has no deductions for COGS or compensation. You take apportioned total revenue, multiply by 0.331%, and that’s your tax bill. The form is one page. The Long Form is multiple pages with supporting schedules for COGS, compensation, and apportionment. EZ saves preparation time and reduces audit exposure (less to audit means less risk of adjustment). But the Long Form often produces a smaller bill, especially for businesses with meaningful deductions.
The crossover point for non-retail businesses is roughly when your largest deduction is 56% of revenue. Above that ratio, the Long Form wins; below it, EZ wins. The math: 0.331% / 0.75% = 44.13%, meaning EZ is cheaper when your margin under the Long Form is more than 44.13% of revenue, or equivalently when your deductions are less than 55.87% of revenue. For retail/wholesale at 0.375% rate, the crossover is much lower: deductions need to exceed about 12% of revenue for the Long Form to win.
Real-world example where EZ wins: a Houston solo financial planning LLC with $900K in revenue, $150K in owner W-2 comp, and zero COGS. Long Form: candidate margins are $630K (70%), $900K (COGS, zero deduction), $750K (comp), and $0 if $1M flat applies. Wait, the $1M flat method only applies to revenue under $20M, which this firm qualifies for, but the deduction can’t exceed revenue, so the effective margin under the $1M method is $0. At 0.75% on $0, the bill is $0. So actually the $1M flat method wins for this firm and beats EZ. But if revenue were $1.5M instead of $900K, the $1M flat method would give margin of $500K times 0.75% equals $3,750, while EZ would give $1.5M times 0.331% equals $4,965. The $1M flat is better at this size.
Real-world example where Long Form (comp method) clearly wins: a 15-person Austin design agency with $4M in revenue, $2.8M in payroll and benefits, and zero COGS. Long Form: margins are $2.8M (70%), $4M (COGS), $1.2M (comp), and $3M ($1M flat). Comp wins at $1.2M of margin times 0.75% equals $9,000. EZ on the same firm: $4M times 0.331% equals $13,240. Comp method beats EZ by $4,240. Service businesses with substantial payroll almost always do better on the Long Form.
Real-world example where EZ wins clearly: a Houston freelance consultancy with $800K in revenue, $50K in W-2 owner comp, and zero COGS. Long Form: margins are $560K (70%), $800K (COGS), $750K (comp), and $0 ($1M flat applies since revenue under $20M, but the deduction is capped at revenue so margin is $0). Wait, actually under §171.101, when computing taxable margin using the $1M deduction, the result floors at zero, not negative. So margin under the $1M method is $0, tax is $0. So this firm pays nothing under the Long Form either. EZ on the same firm: $800K times 0.331% equals $2,648. So Long Form wins here because of the $1M flat deduction.
Common mistakes: assuming EZ is always cheaper because it’s simpler (it’s often not), assuming EZ is only for very small businesses (it’s available up to $20M), not running the comparison and just defaulting to EZ because the form is shorter (a common DIY mistake), and missing the $1M flat deduction option under the Long Form, which often beats EZ for small businesses. We’ve reviewed years of franchise tax returns where the client had been filing EZ every year out of habit and could have saved thousands by switching to the Long Form with the $1M deduction.
Documentation differences: EZ requires essentially nothing beyond the revenue computation. The Long Form requires supporting schedules for whatever deduction method you pick. If you pick the $1M flat deduction, the documentation is light (just the revenue number and the eligibility confirmation). If you pick COGS or compensation, the documentation is heavier. The audit risk follows the documentation complexity, so EZ and $1M flat have lower audit exposure than COGS or comp methods.
Audit considerations: the Comptroller audits both EZ and Long Form returns, but the items at risk differ. EZ audits focus on the total revenue computation: did you correctly exclude flow-through funds, did you start from the right federal gross receipts number, did you apply the right add-backs and exclusions. Long Form audits look at total revenue too, but also at COGS, compensation, and apportionment. Switching from EZ to Long Form can increase audit exposure, but the tax savings usually justify the risk.
Where we add value at The Reed Corporation is running the EZ-vs-Long-Form comparison every year for every Texas client under $20M of revenue, picking the cheaper method, and maintaining the documentation for the chosen method. For clients in the $1M to $5M revenue range, the savings from picking the right method are typically $2,000 to $15,000 a year. For clients in the $5M to $20M range, the savings can be substantially higher. The 30 minutes of comparison work compounds into real money over a decade.
Why do people call it both margin tax and franchise tax — and what’s the actual statutory term?
The statutory term is franchise tax. Texas Tax Code Chapter 171 is titled “Franchise Tax,” and every section within the chapter uses that name. The Comptroller of Public Accounts administers the franchise tax under that statutory name. The forms are titled Franchise Tax Long Form Report (05-158) and Franchise Tax EZ Computation Report (05-169). Official notices, audit letters, and Comptroller communications all use franchise tax. There is no statutory definition of margin tax because margin tax isn’t a statutory term.
The colloquial term margin tax emerged after the 2008 reform under House Bill 3, which restructured the franchise tax to use a margin-based computation. The pre-2008 franchise tax used different bases (earned surplus and taxable capital), and when the 2008 changes introduced the margin computation, practitioners started referring to the new version as the margin tax to distinguish it from the older calculation methodology. The name stuck even though the legal name remained franchise tax. So margin tax is essentially shorthand for the post-2008 franchise tax with its margin-based computation.
The dual naming creates real-world communication problems. CPAs use both terms interchangeably. The Comptroller uses franchise tax officially but slips into margin terminology constantly in form instructions and informal communications. Business owners pick up one term from one source and another from another source and end up confused about whether they’re hearing about the same obligation. We get questions every year that boil down to “do I owe margin tax in addition to franchise tax?” The answer is always no.
Real-world consequence of the naming confusion: an Austin LLC owner who’d been Googling “Texas margin tax payment” couldn’t find his Comptroller account because the Comptroller’s portal uses franchise tax. He called us in late April 2024 panicked that he couldn’t pay a bill he thought was due May 15. We walked him to the Comptroller’s franchise tax page, his account was right there, and he made the payment in five minutes. Lost a week of mental energy because the terminology in his head didn’t match the terminology in the Comptroller’s system.
Why CPAs use both terms: it’s habitual. In conversation with other CPAs, margin tax is faster to say than franchise tax with a margin-based computation. In formal writing or in communications with the Comptroller, franchise tax is the right term. Most practitioners switch between the two without thinking about it, which propagates the confusion. We try to use franchise tax consistently in client communications and explain margin tax as a synonym when it comes up, but the broader profession isn’t disciplined about the distinction.
Common mistakes related to the naming: assuming margin tax is a separate obligation (it isn’t), searching only one term and missing relevant guidance, looking for a “margin tax form” that doesn’t exist (the forms are titled franchise tax), and ignoring Comptroller notices that reference franchise tax when you thought your obligation was margin tax. Each mistake is fundamentally a vocabulary problem rather than a tax problem, but the consequences are real (missed deadlines, late payments, lost good standing).
Documentation: every official document related to this tax uses franchise tax. Comptroller account numbers, Webfile confirmations, payment receipts, audit letters, assessment notices, and refund determinations all reference franchise tax. If you’re keeping a tax file for your Texas entity, label the folder franchise tax (not margin tax) so the contents match what the documents inside say. The label consistency reduces future confusion when you or a preparer pulls the file years later.
Audit considerations: when the Comptroller opens an audit, the letter will say franchise tax audit. The auditor will reference Chapter 171 and use franchise tax terminology throughout. If you’ve been thinking of this as margin tax internally, prepare to translate. The audit is about the same tax regardless of which name you use, and the audit issues (total revenue computation, deduction method, apportionment, supporting documentation) are the same regardless of terminology.
Real-world example of how naming affects appeals: a Houston client received a franchise tax assessment in 2023 for $4,800 based on what the Comptroller said was unreported revenue. The client initially ignored the notice because they thought it was about a different tax (they’d been calling their obligation margin tax and assumed franchise tax was something else). By the time they brought it to us, the 60-day administrative appeal window had nearly closed. We filed the appeal in time, demonstrated that the “unreported revenue” was flow-through funds properly excluded under §171.1011, and got the assessment reversed. But the delay cost them sleep and almost cost them the right to appeal.
Where we add value at The Reed Corporation is using consistent terminology in client communications and explaining the dual naming early in any new engagement so clients don’t get confused later. We use franchise tax in writing, explain margin tax as a synonym when the client uses it, and make sure every document in the client’s file uses the legal name. That consistency saves time and prevents the kind of vocabulary-based mistakes that delay payments or appeals. If you’ve been operating under the assumption that margin tax and franchise tax are different, this is the foundational misunderstanding to clear up before you do any other Texas tax planning.
