LLC Taxes: How Your LLC Is Actually Taxed

For a single-member LLC, LLC taxes start from a simple premise the IRS sets out plainly: your LLC is a disregarded entity. The agency looks straight through the legal wrapper and taxes you as a sole proprietor. There is no separate federal income tax return for the LLC and no separate LLC tax rate. You report the business on Schedule C of Form 1040, list your revenue, subtract your deductible business expenses, and the net profit becomes part of your personal taxable income. That single number then gets hit by two separate taxes, and understanding the split is the whole game with LLC taxes.

The first tax is ordinary income tax at your personal marginal rate. If your LLC nets $90,000 and you have no other income, that $90,000 stacks onto your standard deduction calculation and runs through the federal brackets just like wages would. The second tax is self-employment tax, and this is the one that catches first-year owners off guard. Because you are not an employee with payroll withholding, you owe both the employer and employee halves of Social Security and Medicare yourself: 15.3% total. The Social Security piece (12.4%) applies up to the wage base, $184,500 for 2026, and the Medicare piece (2.9%) has no ceiling. The IRS spells out the rate and the base in its self-employment tax guidance, and it walks through where the numbers land on the return in the Schedule SE instructions.

Here is a worked example so the LLC taxes become concrete. Maria runs a single-member design LLC in New York and nets $90,000 of profit on Schedule C. First the self-employment tax: the IRS lets her treat 92.35% of profit as the SE base, so $90,000 times 0.9235 equals $83,115. Multiply that by 15.3% and she owes about $12,716 in self-employment tax. She gets to deduct half of that, roughly $6,358, as an above-the-line adjustment, which lowers her income-tax base. So for income tax she starts from about $83,642 of business income before her QBI deduction and standard deduction. The Qualified Business Income deduction, made permanent under the 2025 law starting in 2026, can shave up to 20% off her qualified business income, meaningfully cutting the income-tax layer. After the standard deduction and QBI, her federal income tax might land in the $9,000-$11,000 range depending on filing status. Add the two together and Maria’s total federal LLC taxes on $90,000 of profit are roughly $22,000-$24,000, with the SE tax making up more than half of it. That ratio surprises people every single year.

The common mistake with single-member LLC taxes is forgetting the self-employment tax entirely and budgeting only for income tax. Owners look at the brackets, assume a 12% or 22% rate, set aside that much, and then get blindsided by an extra five figures of SE tax at filing. A safe rule of thumb for a profitable single-member LLC is to set aside 25%-30% of net profit for combined federal taxes, then add your state’s bite on top. New York City owners feel this especially because the city layers its own resident tax on income, so the all-in rate on a Manhattan freelancer’s LLC profit can be steep once federal SE tax, federal income tax, New York State tax, and New York City tax all stack. It is not rare for a high-earning city freelancer to send roughly 40 cents of every marginal dollar somewhere, which is exactly why the planning matters more here than almost anywhere else in the country.

The second mistake is failing to make quarterly estimated payments. Since nobody withholds from your draws, the IRS expects four estimated tax payments across the year, roughly April 15, June 15, September 15, and January 15. Skip them and you owe an underpayment penalty even if you pay the full balance in April. Maria should be sending in roughly $5,500-$6,000 each quarter to stay penalty-free. The penalty is effectively non-deductible interest on tax she should have prepaid, so it is pure waste, the kind of avoidable cost that good planning erases entirely. The safe-harbor rule helps here: pay in 100% of last year’s total tax (110% if your prior-year income was high) and the IRS leaves the penalty alone even if you earn far more this year.

A third issue specific to single-member LLC taxes is record-keeping that doesn’t separate business from personal. The disregarded label tempts owners to run everything through one account and sort it out in April. That habit costs deductions, because expenses you can’t document, you can’t claim, and it weakens the liability protection the LLC was supposed to give you. Keep a dedicated business bank account and card from day one, even though the IRS treats the entity as invisible for income tax. Commingling is the single most common reason a clean small business return turns into a painful reconstruction project the following spring.

One more nuance: even though you file no separate income-tax return, you may still file other federal forms. If you have employees, you file payroll returns under the LLC’s EIN. If you pay contractors $2,000 or more, you issue 1099-NEC forms. And while the entity is disregarded for income tax, it is still respected for certain excise and employment taxes. The disregarded label is narrower than people assume, which is one reason it helps to have a professional who handles the whole picture rather than just the 1040. Our individual tax return service covers the Schedule C, the SE tax, the QBI calculation, and the quarterly estimates as one package so nothing falls through the cracks.

The takeaway on single-member LLC taxes is that the structure is administratively simple, one Schedule C, no separate return, but the self-employment tax makes the real rate higher than the bracket suggests. As your profit grows past roughly $80,000-$100,000, that SE tax is exactly what pushes owners to look at an S-corp election. Before you assume your tax is just your bracket, run the SE number first, because that is the line that decides whether your current setup is the cheapest one available to you. If your profit is climbing year over year, model the S-corp comparison this year rather than discovering the gap after you have already overpaid two or three filing seasons in a row.

Multi-member LLC taxes follow a different default path than single-member LLC taxes, and the mechanics trip up partners who expected the same simplicity. The moment your LLC has two or more owners, the IRS stops treating it as a disregarded entity and defaults to partnership taxation. That means a real, separate federal return, Form 1065, and a Schedule K-1 issued to every member. The LLC still pays no federal income tax itself; it remains a pass-through. But the filing burden and the timing of when income hits each partner change in ways that matter for LLC taxes.

Form 1065 is an informational return. It reports the partnership’s total income, deductions, and how everything is allocated among the members. The partnership doesn’t write a check for income tax with this return. Instead it tells the IRS how the pie is sliced, and each member receives a Schedule K-1 showing their share, and that K-1 carries the member’s portion of ordinary business income, separately stated items like interest or capital gains, and the self-employment income subject to the 15.3% SE tax. Each member then reports the K-1 figures on their personal Form 1040.

The single most important and most misunderstood feature of multi-member LLC taxes is that you are taxed on your allocated share whether or not you take any cash out. This is “phantom income.” Suppose two partners split a consulting LLC 50/50 and it nets $120,000, but they agree to leave $60,000 in the business to fund next year’s hiring. Each partner still receives a K-1 reporting $60,000 of income and owes tax on it, even though each only took $30,000 in actual distributions. The IRS taxes the allocation, not the withdrawal. Partners who don’t plan for this find themselves owing tax on money still sitting in the company bank account, which is why good operating agreements include mandatory tax distributions, cash sent to each partner specifically to cover the tax on their K-1.

A worked example makes the LLC taxes clearer. Alex and Jordan own a marketing LLC, splitting profits 60/40. The LLC nets $200,000. On Form 1065, the income is allocated: Alex gets a K-1 for $120,000, Jordan for $80,000. Both are active, so their shares are subject to self-employment tax. Alex’s SE tax runs roughly $120,000 times 0.9235 times 15.3%, adjusted where Social Security stops at the $184,500 wage base, landing in the $16,000-$17,000 range. Jordan’s runs on $80,000, roughly $11,300. Each then pays personal income tax on their share, reduced by the QBI deduction if they qualify under the 2026 thresholds. Notice that even though they’re in the same business, their LLC taxes differ because their profit shares differ, and a partner who took less cash than their allocation can still owe the most tax. If Alex pulled out only $90,000 in cash but was allocated $120,000, he still pays tax on the full $120,000, with the extra $30,000 increasing his basis in the partnership for later.

The common mistake with multi-member LLC taxes is missing the Form 1065 deadline. The partnership return is due March 15, a full month before the personal return, and the penalty for late filing is brutal: under the rules in the Form 1065 instructions, it accrues per partner, per month. A two-member LLC that files Form 1065 three months late can owe well over a thousand dollars in penalties before anyone has paid a dime of actual tax. Partners often don’t realize the business return comes first and has its own due date, separate from the April personal deadline. If you need more time, file Form 7004 by March 15 for an automatic extension rather than blowing past the date and hoping for the best.

A second mistake is sloppy allocations that don’t match the operating agreement, or special allocations that lack “substantial economic effect,” the IRS test for whether an unusual profit split is respected. If your agreement says 60/40 but the books split things differently, or if you try to allocate all the deductions to the high-bracket partner without economic substance, the IRS can recharacterize the whole thing. Multi-member LLC taxes reward a clean, consistent set of books that tie to the agreement. Sloppy capital-account tracking is one of the fastest ways to turn a routine partnership return into an examination, and capital accounts that drift out of line with the agreement are a classic audit flag.

A third issue is guaranteed payments. When a partner is paid a fixed amount for services regardless of profit, that’s a guaranteed payment, deductible by the partnership and ordinary income subject to SE tax for the recipient. Owners often confuse guaranteed payments with distributions and report them wrong, which throws off both the 1065 and the individual returns. Getting the character right matters because it changes each partner’s self-employment income and, in turn, their LLC taxes. A related trap is the disappearing basis problem: a partner can only deduct losses up to their basis in the partnership, which rises with contributions and allocated income and falls with distributions and allocated losses. A member who has taken out more than they put in plus their share of profit can find a loss suspended, carried forward until basis returns, which feels unfair the year it happens but is exactly how the rules work.

Married couples get a special wrinkle. A multi-member LLC owned solely by spouses in a community-property state can sometimes elect to be treated as a single disregarded entity, simplifying their LLC taxes back to a Schedule C split. Outside community-property states, a husband-wife LLC is generally a partnership filing Form 1065. The IRS LLC classification page covers these edge cases, and the answer turns on where you live, not on what you’d prefer.

If your multi-member LLC is growing, our partnership return service handles the 1065, the K-1s, and the allocation review so the numbers tie out and the deadlines get met. Build the tax-distribution language into your operating agreement before profits grow, because retrofitting it after a partner gets a surprise K-1 bill is how partnerships start to fracture, and that fracture is far more expensive than the tax itself. The partners who treat the 1065 as a March priority, not an April afterthought, are the ones who keep their LLC taxes predictable.

The S-corp election is the single biggest lever in LLC taxes, and it’s also the most oversold. Done at the right profit level it can save thousands a year; done too early it costs more than it saves and creates audit exposure. The election works by changing how your LLC’s profit gets exposed to the 15.3% self-employment tax. Understanding that one mechanism tells you exactly when it helps your LLC taxes and when it’s a trap.

Under default pass-through treatment, every dollar of your active LLC profit is subject to self-employment tax. Net $150,000 on Schedule C and roughly $138,500 of it (after the 92.35% factor) faces the 15.3% load, though the Social Security portion stops at the $184,500 wage base. When your LLC elects S-corp treatment by filing Form 2553, the math splits in two. You become an owner-employee. You pay yourself a W-2 salary, and only that salary carries Social Security and Medicare tax. The remaining profit flows to you as a distribution, and distributions are not subject to self-employment tax. That gap between your salary and your total profit is where the LLC taxes savings live.

The constraint is the word “reasonable.” The IRS requires S-corp shareholder-employees to pay a reasonable salary for the services they perform before taking distributions. You cannot pay yourself $20,000 and route $130,000 as a tax-free distribution; that’s the classic abuse the IRS audits for, and the agency’s broader S corporation guidance makes clear that misclassified wages get recharacterized with penalties. Reasonable means what you’d pay someone else to do your job, judged against industry data, your hours, your role, and your experience. If a similar professional earns $80,000, that’s roughly your floor.

Here’s the worked example that shows when the S-corp election helps LLC taxes. Sam’s consulting LLC nets $150,000. Under the default, SE tax is roughly $150,000 times 0.9235 times the blended rate, landing around $19,000-$20,000 once you account for the Social Security cap. Now Sam elects S-corp status and pays a reasonable salary of $80,000. The payroll taxes on that salary are about $12,240 (15.3% of $80,000). The remaining $70,000 comes out as a distribution with zero self-employment tax. Sam’s payroll-tax bill drops from roughly $19,000 to about $12,240, a savings near $6,700 a year. Income tax is roughly the same either way, since both the salary and the distribution are still taxable income, so the savings are specifically on the SE/payroll side. That $6,700 is real money, and it repeats every year the profit holds.

Now run it at a lower profit to see the trap. Take an LLC netting $50,000. A reasonable salary might be $40,000, leaving only $10,000 as a distribution. The SE-tax savings on that $10,000 is about $1,530. But running an S-corp costs money: a separate Form 1120-S return, payroll processing with quarterly 941 filings and W-2s, state S-corp fees, and usually higher accounting fees, often $1,500-$3,000 a year combined. At $50,000 of profit, the costs eat the savings whole. This is why an S-corp election lowers LLC taxes only above a threshold, generally somewhere around $60,000-$80,000 of net profit where a defensible salary still leaves a healthy distribution. Below that line, the election is a net loss dressed up as a strategy.

The most common mistake is electing too early because someone online said “S-corps save on taxes.” That advice ignores the cost side and the reasonable-salary floor entirely. The second mistake is electing and then setting an unreasonably low salary to pad the distribution; that invites the IRS to recharacterize distributions as wages, with back payroll taxes and penalties. The third is missing the Form 2553 deadline. The election is generally due within two months and fifteen days of the start of the tax year you want it to apply, though late-election relief exists under IRS procedures if you have reasonable cause and have otherwise acted as an S corporation. A fourth, quieter mistake is electing S-corp status and then failing to actually run payroll, paying yourself only distributions, which defeats the entire arrangement and hands an auditor an easy adjustment.

There’s also a planning bonus and a planning cost worth weighing carefully. The S-corp salary creates earned income that supports a Solo 401(k) and can interact with the QBI deduction in useful ways, but the salary also reduces QBI, so the optimal salary balances SE-tax savings against the QBI haircut. That balancing is genuinely worth a professional’s time, because the wrong salary can give back in lost QBI more than it saves in SE tax. Set the salary too low and you invite an audit; set it too high and you overpay payroll tax and shrink your QBI deduction. The sweet spot is specific to your numbers, not a generic percentage of profit, despite what the “pay yourself 40% of profit” crowd online suggests.

State treatment adds another layer. Some states, including New York and California, impose their own taxes or fees on S corporations that can chip away at the federal savings. California charges S-corps a 1.5% franchise tax with an $800 minimum, and New York City does not recognize the federal S election at all, taxing S-corps under the general corporation tax. New York State recognizes the S election only if you file a separate state election, Form CT-6, so an owner who elects federally and assumes the state follows automatically can get a surprise notice. Run those state costs into the same spreadsheet as the federal SE-tax savings, because a $6,700 federal win that’s partly clawed back by $1,500 of state S-corp tax and a city that ignores the election entirely is a smaller win than the headline number suggests. So the federal SE-tax savings can be partly offset by state-level costs, which is one more reason the election deserves a real calculation rather than a rule of thumb. Our tax strategy consulting team runs the side-by-side on your actual numbers, federal and state, rather than a generic rule. The honest position on LLC taxes is that the S-corp election is a powerful tool at the right income, a needless expense at the wrong one, and never something to elect blind. Model your specific numbers before the election deadline, because the savings only compound for owners who set the salary defensibly and revisit it as profit grows.

Yes, and both of these shape the real cost of LLC taxes more than owners expect. The Qualified Business Income deduction is the biggest break available to pass-through LLC owners, and the quarterly estimated tax system is the obligation that, if ignored, quietly adds penalties to your LLC taxes. They pull in opposite directions: one lowers your bill, the other forces you to pay it on a schedule. Handling both well is most of what good planning for LLC taxes looks like.

Start with the QBI deduction, found in Section 199A of the tax code. It lets eligible owners of pass-through businesses, including single-member and multi-member LLCs taxed as sole proprietorships or partnerships, deduct up to 20% of their qualified business income. On $100,000 of qualified income, that’s a potential $20,000 deduction that never gets taxed. The big recent news for LLC taxes is permanence: the One Big Beautiful Bill Act, signed in 2025, removed the scheduled sunset and made the QBI deduction a permanent feature starting in 2026. For years owners planned around a 2025 expiration that no longer exists, so the deduction is now a durable part of LLC taxes rather than a temporary one. The IRS keeps the mechanics current on its Qualified Business Income deduction page.

Eligibility hinges on taxable income. For 2026, full QBI eligibility runs up to $201,750 of taxable income for single filers and $403,500 for joint filers. Below those thresholds, almost any qualified business gets the full 20%. Above them, the rules get stricter, especially for “specified service trades or businesses” like consulting, law, accounting, and health, which phase out and can lose the deduction entirely at higher incomes. The deduction is also limited by W-2 wages the business pays and by the unadjusted basis of business property once you’re over the threshold, which is one more reason an S-corp salary interacts with QBI in ways worth modeling rather than guessing. A service-business owner sitting just above the threshold sometimes finds that a deductible retirement contribution drops taxable income back under the line and restores the full 20%, a planning move that pays for itself.

A worked example shows the QBI effect on LLC taxes. Priya’s single-member LLC nets $120,000, and her taxable income after the standard deduction is around $105,000, comfortably under the single threshold. Her QBI is roughly her business profit less the deductible half of SE tax, call it about $111,500. Twenty percent of that is roughly $22,300, but the deduction is also capped at 20% of taxable income minus net capital gains, so she takes the lesser figure. Either way, she’s deducting somewhere around $21,000-$22,000, which at her marginal rate saves her several thousand dollars in income tax. That deduction doesn’t touch her self-employment tax, only her income tax, a distinction owners constantly blur and one that explains why two LLCs with the same QBI can still owe very different totals.

Now estimated taxes, the enforcement side of LLC taxes. Because no employer withholds from your LLC income, the IRS expects you to prepay through four estimated tax payments due roughly April 15, June 15, September 15, and January 15. These payments must cover both your income tax and your self-employment tax. The IRS uses a safe-harbor rule: you generally avoid the underpayment penalty if you pay at least 90% of the current year’s tax or 100% of last year’s (110% if your prior-year adjusted gross income exceeded $150,000). Hit the safe harbor and you’re penalty-proof even if you owe more at filing, which is the single most useful planning fact for any new LLC owner to internalize.

The common mistake with estimated taxes is treating them as optional and paying everything in April. The underpayment penalty is effectively interest on the tax you should have prepaid, and it accrues quarter by quarter. An LLC owner who owes $24,000 and pays nothing until April can face several hundred dollars in penalty on top, money that buys nothing. Another mistake is forgetting that estimated payments must include SE tax, not just income tax; owners size their quarterly checks off their bracket alone and come up thousands short. A third is ignoring state estimates, since New York, California, and most states run their own parallel quarterly systems with their own due dates and their own penalties, and the state penalty is a separate bill from the federal one.

There’s a timing quirk that trips people up too. The four estimated periods are not evenly spaced. The first covers January through March and is due in April, but the second covers only April and May and is due in June, which means the second payment arrives just two months after the first. Owners who set a quarterly calendar reminder for “every three months” miss the June deadline routinely, then watch a small penalty accrue on the shortfall for the rest of the year. One reliable workaround for owners who also draw a W-2 paycheck somewhere, say a freelancer with a part-time employer or a spouse with wages, is to bump up withholding on that paycheck instead of sending estimates. Withholding is treated as paid evenly across the year no matter when it’s actually withheld, so a year-end withholding increase can cure an underpayment that estimated payments alone couldn’t fix. It’s one of the few legitimate ways to retroactively patch a missed quarter. If your income is lumpy, say a freelancer who lands a big project in Q3, the annualized installment method lets you pay more in the quarter you actually earned the income rather than spreading it evenly, which can cut the penalty when earnings are uneven across the year.

The practical workflow for LLC taxes ties them together. Project your annual net profit, subtract the deductible half of SE tax, apply the QBI deduction to estimate income tax, add full SE tax, then divide the total across four quarters and send it in on time. Adjust mid-year if profit swings up or down. We build exactly this kind of projection for clients through our business management service so the quarterly numbers aren’t guesses and nobody gets a December surprise. The forward-looking point is that with QBI now permanent, pass-through LLC owners have a stable deduction to plan around for the first time in years, which makes building a disciplined quarterly estimate worth far more than scrambling each April. Treat the deduction as a fixed feature and the estimates as a fixed calendar, and your LLC taxes stop being a once-a-year shock and become a managed monthly number.

Federal LLC taxes are only half the picture, and the state side is where owners get the most unpleasant surprises. Several states charge an LLC simply for existing, regardless of whether it made a profit, and the rules vary so widely that what’s nearly free in one state costs over a thousand dollars in another. If you’re forming or running an LLC, the state LLC taxes and fees often decide whether the entity is worth keeping open in a low-revenue year.

California is the headline example, and it’s harsh. The state imposes an $800 annual minimum franchise tax on essentially every LLC, due whether the business earned a dollar or lost money all year. On top of that, California adds a gross-receipts LLC fee once revenue crosses $250,000, scaling up to several thousand dollars for high-revenue LLCs: roughly $900 at $250,000 of receipts, climbing to about $11,790 at $5 million and above. So a California LLC grossing $400,000 pays the $800 minimum plus a $2,500 fee, $3,300 in state LLC taxes before income tax even enters the conversation. A temporary first-year exemption from the $800 existed for LLCs formed in earlier years, but that relief has been winding down, so don’t assume your new California LLC skips the first-year bill; confirm the current rule on the Franchise Tax Board site before you count on it. The gross-receipts fee is also based on total revenue, not profit, so a high-volume low-margin California LLC can owe a four-figure fee in a year it barely broke even.

New York handles state LLC taxes differently but no less expensively at formation. There’s no flat $800 minimum, but New York imposes a one-time publication requirement: within 120 days of forming, you must publish a notice of your LLC in two newspapers, one daily and one weekly, designated by the county clerk, for six consecutive weeks, then file a Certificate of Publication with a $50 fee. The cost depends entirely on the county, because newspaper rates vary wildly. In upstate counties this might run $300-$600. In Manhattan (New York County), where advertising rates are notoriously high, publication can exceed $1,500-$2,000. It’s the same Section 206 legal requirement; the price just depends on where your LLC’s office sits. This is one of the more frustrating LLC taxes for New York City owners precisely because it’s geography, not income, that drives the cost, and missing the 120-day window can suspend the LLC’s authority to do business in the state.

New York also charges an annual LLC filing fee for LLCs treated as partnerships or disregarded entities with New York-source income, ranging from $25 up to $4,500 depending on gross income. So a multi-member New York LLC with strong revenue pays this annual fee on top of any New York City unincorporated business tax that may apply to its owners. New York City’s UBT is a separate layer many LLC owners in the five boroughs overlook entirely, and it can apply even when the federal LLC taxes are modest. The UBT runs 4% on net business income above an exemption, and for a profitable Manhattan LLC that’s a real number the federal calculation never hinted at.

A worked comparison illustrates how much state LLC taxes can swing the total. Take two single-member consulting LLCs, each netting $150,000, identical at the federal level. The California LLC owes the $800 minimum plus, on gross receipts likely under $250,000 for a lean service business, possibly no gross-receipts fee, so roughly $800 in state-specific LLC fees, plus California’s personal income tax on the profit, which is among the steepest in the country, topping out above 13% at the high end. The New York LLC paid maybe $1,200 once for publication, then owes a modest annual filing fee plus New York and possibly New York City tax on the owner’s income, including the UBT. Same federal LLC taxes, very different state add-ons, and the difference compounds every year the entity stays open. Run the same business in Texas or Florida, which levy no personal income tax, and the state-level LLC taxes nearly vanish, though Texas has its own franchise/margin tax above a revenue threshold.

The common mistake with state LLC taxes is forming an LLC in a “tax-friendly” state like Delaware, Nevada, or Wyoming while actually doing business where you live. If you live and work in California or New York, registering in Wyoming doesn’t escape your home state’s LLC taxes. You become a foreign LLC that still has to register in your home state, pay that state’s fees, and file there, so you end up paying twice, plus a registered-agent bill in the other state. For most small owners, forming in your home state is simpler and cheaper despite the marketing that says otherwise. The Delaware advantage is real for venture-backed startups that need its corporate law and courts; it is almost never real for a one-person consulting LLC. There’s also a sales-and-use tax wrinkle that has nothing to do with income tax but catches product sellers: once your LLC has enough sales into a state, even online, you can trigger economic nexus and owe that state’s sales tax collection duties, a separate registration on top of the income-tax fees discussed here. The threshold in many states sits around $100,000 in sales or 200 transactions, so a growing e-commerce LLC can owe filings in a dozen states without ever setting foot in them.

A second mistake is dissolving an LLC improperly and continuing to accrue the annual fee. California will keep billing the $800 until the LLC is formally cancelled with the state, and owners who just “stop using” an LLC can rack up years of minimum tax plus penalties on an entity that earns nothing. If you’re done with an entity, close it properly, file the final returns, and cancel the registration with the state. For owners navigating multi-state exposure, our state tax questions guide and our advisory team can map where you actually owe. The forward-looking lesson on state LLC taxes: factor your home state’s annual cost into the decision to form at all, because in a slow year the state can be the only party that still gets paid, and that math should inform whether the entity earns its keep year after year.
