Tax Compliance for Small Businesses in Austin

An Austin small business has a compliance list that is genuinely shorter than one in a state with an income tax, but every item on it still carries a deadline and a penalty for missing it. Start federal, because that is where the income tax lives. You file an annual income tax return, the form depending on your structure, a Schedule C attached to your personal Form 1040 for a sole proprietor or single-member LLC, an 1120-S for an S corporation, or an 1120 for a C corporation. If you have no withholding you fund four quarterly estimated payments. If you have employees you file quarterly 941 payroll returns, make federal tax deposits, and issue W-2s at year-end. If you pay contractors you issue 1099-NEC forms, and for 2026 that threshold rose from $600 to $2,000, so fewer small payments are reportable than in prior years.

On the Texas side there are two filings, and neither is an income tax, which is exactly why owners forget them. The first is sales and use tax. If you sell taxable goods or certain services, you register with the Comptroller, collect tax at the combined Austin rate of about 8.25 percent, and remit it on the schedule the state assigns, frequently monthly. The second is the annual franchise tax report, due in May, which every LLC, corporation, and most partnerships must file whether or not any franchise tax is owed, along with a Public Information Report or Ownership Information Report. What you do not file in Austin is a state income tax return or state income estimates, because Texas has no personal income tax, and that absence is a real simplification compared with California or New York. One additional point is that the sales tax filing frequency itself depends on volume, the Comptroller assigns monthly, quarterly, or annual filing based on how much tax you collect, so a growing business can find its filing cadence changing as it scales, which is one more reason to have someone tracking the schedule rather than relying on last year’s rhythm.

Here is a worked example of the full picture. Suppose your Austin business is an S corporation with three employees doing $900,000 in revenue. Your compliance year includes the federal 1120-S, your personal 1040 reflecting the K-1, four federal estimates, four quarterly 941s with deposits, year-end W-2s for the staff and 1099-NEC forms for any contractors paid $2,000 or more, monthly sales tax remittances on your taxable sales, and the May franchise report filed at zero because $900,000 is well under the roughly $2.65 million no-tax-due threshold. That is a busy but manageable calendar, and the only truly state-specific pieces are the sales tax and the franchise report. We keep all of it on one schedule through bookkeeping and coordinated filing, and the broader picture of operating here sits on our Austin small business page. The federal duties are at the IRS Small Business and Self-Employed Tax Center and the Texas filings at the Texas Comptroller.

The two Texas obligations that catch Austin owners off guard are the franchise tax report and the sales tax, and they surprise people for opposite reasons. The franchise report surprises owners because they assume no tax means no filing. Texas runs a franchise tax, also called the margin tax, but it only produces tax once annualized revenue crosses a no-tax-due threshold sitting around $2.65 million, so the overwhelming majority of small businesses owe nothing. The trap is that owing nothing does not excuse you from filing, the report and an accompanying Public Information Report or Ownership Information Report are due every May regardless. Owners who reason that a zero balance means they can ignore it discover, sometimes a year or two later, that the Comptroller has forfeited the entity’s right to transact business in Texas for the missed report, which can suspend the right to bring a lawsuit and expose the owners personally until the entity is reinstated.

The sales tax surprises owners for the opposite reason, because the money feels like theirs when it is not. When you collect sales tax from a customer, that money belongs to the state from the moment of collection, you are simply holding it in trust until you remit it. A business that treats those collections as part of its cash and spends them to cover a slow month builds a sales tax balance it cannot pay, and because sales tax is a trust-fund tax, the state can pursue the responsible individual personally, piercing the usual liability protection of the entity. This is a different and more dangerous kind of debt than an ordinary bill, and it accumulates quietly on every taxable sale at the roughly 8.25 percent Austin rate. A related surprise is the taxability question itself, because Texas taxes some services and not others, and an owner who assumed services were exempt can find after an audit that they should have been collecting all along, which turns an oversight into a personal liability for tax they never charged the customer.

Here is a worked example. Suppose an Austin retailer does $600,000 of taxable sales in a year and collects about $49,500 in sales tax at 8.25 percent. If cash gets tight and the owner uses part of those collections to make payroll, intending to catch up, a $15,000 sales tax shortfall can build across a couple of quarters. Meanwhile the business, an LLC well under the franchise threshold, also forgets its May franchise report because no tax was due. Now there are two Texas problems at once, a trust-fund sales tax balance the state can assess against the owner personally, and a franchise forfeiture that clouds the entity’s standing. Both were entirely preventable with timely filing and by keeping the sales tax segregated. We track the sales tax as a liability so it is never spent and file the franchise report on time even at zero through tax compliance and clean bookkeeping. The franchise rules are at the Texas Comptroller franchise tax pages and the sales tax rules at the Texas Comptroller sales and use tax pages.

Estimated taxes for an Austin small business are federal only, and that is one of the real conveniences of running a business in Texas, because there is no state income tax and therefore no parallel state estimate on your business income. The federal tax system is pay-as-you-go, so a business without withholding has to send the IRS its income tax and self-employment or payroll tax four times a year rather than in one April payment. The 2026 due dates are April 15, June 15, September 15, and January 15, 2027. Miss them and you owe an underpayment penalty that functions like interest on what you should have paid and when, even if you pay the full balance at filing. The penalty is calculated quarter by quarter, so being late on just the first installment costs you even if you overpay the rest of the year to catch up, which is why the timing of each payment matters as much as the total.

The safe harbor is the tool that takes the guesswork out. If you pay in at least 100 percent of last year’s total tax, or 110 percent when your prior-year adjusted gross income was over $150,000, you are shielded from the federal underpayment penalty no matter how the current year turns out. That lets an Austin business fund estimates off a known number instead of forecasting a year that has not finished. Because Texas imposes no income tax, that federal safe harbor is the entire framework, not half of it, so the cash planning is cleaner than it would be almost anywhere with a state income tax to layer on top. For a business with uneven income, there is also the annualized income installment method, which lets you base each quarterly payment on what you have actually earned through that point in the year rather than a flat one-fourth, so a business that earns most of its money late in the year does not have to overpay early, though it takes more calculation to run.

Here is a worked example. Suppose your Austin business owed $36,000 in total federal tax last year and this year looks similar or a little higher. The 100 percent safe harbor means paying in $36,000 across the four quarters, about $9,000 each, and you are penalty-proof even if this year’s bill lands at $42,000. You would still owe the $6,000 difference at filing, but with no penalty attached, and there is no state estimate to add on top. Where owners get burned is treating estimates as optional in a growth year, an Austin business that jumps from $100,000 to $240,000 of profit and keeps paying last year’s small estimates will owe a large federal balance in April, and while the safe harbor spares the penalty, the cash still has to be there. Two Texas items hit the same cash even though they are not income estimates, the sales tax remitted monthly and the franchise tax if you have crossed the revenue threshold, paid by May. We build one calendar covering the federal quarters, the sales tax, and the franchise report through tax strategy consulting and tie the set-aside to your bookkeeping. The rules are at the IRS estimated taxes page.

Good tax compliance for an Austin small business is largely about avoiding a specific set of penalties, and several of them are unique to Texas or made worse by the trust-fund nature of the taxes involved. The first is the federal late-filing and late-payment penalty. File a federal return late and the penalty can run 5 percent of the unpaid tax per month up to 25 percent, and pay late and a separate penalty plus interest accrues. These are ordinary but they add up fast, and they are entirely avoidable by filing and paying on time.

The second is the federal estimated-tax underpayment penalty, which hits a business that does not fund its quarterly estimates. It works like interest on the shortfall for the period it was unpaid, and the safe harbor of 100 or 110 percent of last year’s tax is what protects against it. The third, and the most dangerous, is the trust-fund penalty. Sales tax you collect and payroll tax you withhold are trust-fund taxes, money that belongs to the government from the moment you take it, and if you fail to remit it the state or the IRS can assess the responsible person individually, reaching past the entity to your personal assets. A business that spends its sales tax collections to cover operations is exposed to this personally, which makes it a far graver risk than an ordinary unpaid bill. The fourth is the Texas franchise forfeiture, which is not a dollar penalty so much as a loss of standing, the Comptroller can forfeit the entity’s right to transact business in Texas for a missed franchise report, suspending its ability to sue and exposing the owners, and reinstatement takes filing the delinquent reports and paying penalties. There is also interest running underneath most of these, so a balance left unresolved keeps growing even after the flat penalties cap out, which is why engaging early rather than waiting for a notice almost always costs less in the end.

Here is a worked example. Suppose an Austin business has a rough year and lets three things slide, it files its federal return two months late owing $20,000, it underfunds its estimates, and it spends $12,000 of collected sales tax to make payroll. The late-filing penalty alone could be around $2,000, the underpayment penalty adds a few hundred more, and the $12,000 sales tax becomes a trust-fund liability the state can assess against the owner personally, plus the business skipped its May franchise report and is drifting toward forfeiture. Every one of those was preventable. With compliance handled, the return is filed on time, the estimates are funded to the safe harbor, the sales tax is segregated and remitted, and the franchise report is filed at zero, so none of the penalties ever accrue. We keep the whole calendar current through tax compliance and the payroll deposits through payroll compliance. The federal penalty rules are at the IRS Small Business and Self-Employed Tax Center and the Texas obligations at the Texas Comptroller.

Yes, and getting current is almost always cheaper and less stressful than owners fear, because the penalties grow the longer you wait and the state and the IRS both offer paths to resolution once you engage. The first step is an honest inventory of what is actually behind. For an Austin business that usually means some combination of unfiled federal returns, missed federal estimates, unremitted sales tax, and skipped franchise reports. Each has its own fix, and the order matters, because some problems compound faster than others. The most urgent is usually unremitted sales tax, because it is a trust-fund liability the state can assess against you personally, so stopping the bleeding there, filing the delinquent sales tax returns and arranging to pay the balance, comes first.

Next is the franchise report, because a missed report can put the entity into forfeiture, and if you have been forfeited you cannot cleanly sign contracts, borrow, or bring a lawsuit in Texas until you reinstate. Reinstatement means filing the delinquent franchise reports and the Public Information Report and paying any penalties, after which the Comptroller restores the entity’s standing. Then the federal returns, filed as far back as required, which often turns out better than expected because the business may have had deductions it never claimed, sometimes reducing the balance or even producing a refund on a year still open for it. Where a real balance remains, the IRS offers installment agreements, and the state offers payment plans for sales tax, both of which stop the escalation as long as you stay current going forward. In some cases penalties can be reduced too, the IRS offers first-time penalty abatement for an otherwise compliant taxpayer, and demonstrating reasonable cause can waive penalties on both the federal and state side, so part of a good catch-up is asking for relief that owners handling it alone rarely think to request. The sooner you start, the more of these doors are open, because some relief is only available before the agency has assessed the balance and started enforced collection.

Here is a worked example. Suppose an Austin business comes to us two years behind, with no franchise reports filed, one unfiled federal return, and about $18,000 of sales tax collected but not remitted. We file the two years of franchise reports at zero because the business was under the threshold, curing the forfeiture and reinstating the entity. We prepare and file the missing federal return, and because the business had unclaimed equipment depreciation, the balance comes in lower than the owner expected. We file the delinquent sales tax returns and set up a payment plan for the $18,000 before the state escalates to a personal assessment. Within a couple of months the business is filed current, its Texas standing is restored, and the remaining balance is on a manageable plan rather than growing. We handle the whole catch-up through tax compliance and keep it from recurring with ongoing bookkeeping. The reinstatement and franchise rules are at the Texas Comptroller franchise tax pages, and the federal catch-up guidance is at the IRS Small Business and Self-Employed Tax Center.
