What Form 05-158 Is For
Form 05-158 is the long form used to report and pay Texas franchise tax, which is essentially a privilege tax for doing business in Texas. Think of it as the state's way of collecting revenue from entities that operate within its borders or are formed under Texas law.
The franchise tax isn't based on your profits like traditional income tax. Instead, it's calculated on your business's "margin"—a measure that can be computed several different ways depending on what's most favorable for your situation. The form comes in two pages (05-158-A and 05-158-B) that work together to capture your revenue information, calculate your taxable margin, apply the appropriate tax rate, and determine what you owe.

Preguntas frecuentes
If my business made a profit but my calculated tax is under $1,000, do I still need to file?
Yes, if your annualized total revenue exceeds the no-tax-due threshold ($2.47 million for 2025), you must file Form 05-158 even if your calculated tax is under $1,000. The good news is you won't owe any tax—Texas has a minimum threshold where taxes under $1,000 aren't collected. But you still need to file the report to prove you qualify for the zero tax. You also must file your required information report.
Can I use the EZ Computation instead of the long form?
Possibly. For reports due in 2024 and later, entities with annualized total revenue of $20 million or less can elect to use Form 05-169 (EZ Computation). This simplified method multiplies your total revenue by your apportionment factor, then applies the tax rate directly. You give up the ability to deduct cost of goods sold, compensation, or claim credits, but the calculation is much simpler. It's worth running the numbers both ways to see which saves you more money.
What if I operate in multiple states—do I pay Texas tax on all my revenue?
No. Texas uses an apportionment formula based on gross receipts. You calculate what percentage of your receipts come from Texas sources, then apply that percentage to your taxable margin. This ensures you're only paying Texas franchise tax on the portion of your business activity that occurs in Texas. The instructions provide detailed sourcing rules for different types of receipts.
Do I need to make estimated quarterly payments like federal taxes?
No. Texas franchise tax doesn't require quarterly estimated payments. You file once per year and pay the full amount due with your annual report. This simplifies cash flow planning compared to federal taxes, though it also means you need to budget for a potentially large payment each May.
What happens if I miss the deadline entirely?
Missing the May 15 deadline triggers an automatic $50 late filing penalty, regardless of whether you owe tax. If you owe tax, additional penalties apply: 5% if you're 1-30 days late, 10% after 30 days. Interest also accrues on unpaid tax. More seriously, continued failure to file can result in forfeiture of your right to do business in Texas. The Comptroller will send notices of intent to forfeit, and eventually your entity can lose its legal standing. File as soon as possible, even if late, to minimize penalties and avoid forfeiture.
Can I amend my return if I discover an error after filing?
Yes. You can file an amended Form 05-158 to correct mathematical errors, change your margin computation method, add deductions you initially missed, or support a refund claim. Write “AMENDED REFUND” at the top if the amendment results in overpayment, and include a detailed letter explaining what you're correcting and why. Remember that amendments seeking refunds must be filed within the statute of limitations period to be valid.
My business closed mid-year—do I still have to file?
Yes. If your business closes, you need to file a final franchise tax report covering the period from your last accounting year-end through the date you ceased business. You'll also need to file any required annual reports you missed. Write “PREMATURE” across the top if you're closing in your first year before your normal accounting period ends. Additionally, file Form 05-359 (Certificate of Account Status) to officially terminate your franchise tax obligation and, if applicable, your registration with the Texas Secretary of State.
