Texas Sales Tax: Rates, Filing Frequency, Due Dates and Audits
Texas Sales Tax: Rates, Filing Frequency, Due Dates and Audits
Texas sales tax is administered by the Texas Comptroller of Public Accounts. It applies to the sale of tangible personal property and certain services, and every business that collects it must understand registration requirements, filing deadlines, and compliance rules. This guide covers the rates, filing schedules, due dates, and what to expect in an audit.
Texas Sales Tax Rate: State and Local Combined
The Texas state sales tax rate is 6.25%. However, most businesses do not collect this rate alone. Local jurisdictions (cities and counties) add their own rates on top of the state rate.
The combined state and local sales tax rate ranges from 6.25% (state only in areas with no local rate) to a maximum of 8.25%. Because local rates vary significantly by location, you must use the official Comptroller's Sales Tax Rate Locator to find the exact rate for each address where you do business. The locator is available on the Comptroller's website at comptroller.texas.gov/taxes.
If you have multiple business locations across Texas, each location may be subject to a different combined rate. It is critical to verify the rate for each location before you file, since you must report the correct amount of tax collected.
Who Must Register and Collect Sales Tax
Any business that sells taxable tangible personal property or certain services in Texas must register for a sales and use tax permit. Taxable sales include retail sales of goods, as well as specific services such as:
- Landscaping and lawn care
- Building cleaning and janitorial services
- Garbage removal
- Structural pest control
- Surveying
The Comptroller issues sales tax permits at no charge. Once you apply, the Comptroller assigns your business to either monthly, quarterly, or yearly filing based on your expected tax liability. The assignment typically happens after your permit is approved.
Economic Nexus and Out-of-State Sellers
If you are an out-of-state seller (remote seller) with no physical location in Texas, you still must register and collect Texas sales tax once your revenue in Texas exceeds a threshold. Specifically, remote sellers must register once total Texas revenue exceeds $500,000 in the preceding 12 calendar months.
This economic nexus rule means that even if you ship products into Texas from another state, you are responsible for collecting and remitting the applicable sales tax once you cross the revenue threshold. Tracking your rolling 12-month revenue is therefore essential if you operate an e-commerce business or sell services across state lines.
Sales Tax Filing Frequency: Monthly, Quarterly, or Yearly
The Texas Comptroller assigns your business one of three filing frequencies:
- Monthly filers report sales tax every month.
- Quarterly filers report sales tax four times per year.
- Yearly filers report sales tax once per year (less common).
The Comptroller determines your filing frequency when your permit is issued, typically based on the amount of tax you are expected to owe. Businesses with higher expected tax liability are usually assigned monthly filing; those with lower liability may be assigned quarterly or yearly filing.
If your tax liability changes significantly after your initial assignment, you may request a change in filing frequency by contacting the Comptroller directly.
Sales Tax Due Dates and Payment Schedule
Missing a sales tax deadline carries real penalties. Know your due date and mark it clearly on your calendar.
Monthly Filers
If you file monthly, your sales tax report is due on the 20th of the month following the reporting month. For example, sales made in January are reported by February 20. If the 20th falls on a weekend or holiday, the deadline moves to the next working day.
Quarterly Filers
If you file quarterly, your reports are due on:
- April 20 (for the January to March quarter)
- July 20 (for the April to June quarter)
- October 20 (for the July to September quarter)
- January 20 (for the October to December quarter)
Yearly Filers
If you file yearly, your report is due on January 20 of the following year. For example, sales made in calendar year 2026 are reported by January 20, 2027.
Weekend and Holiday Rule
If any due date falls on a Saturday, Sunday, or state holiday, the deadline automatically moves to the next working day. Always verify your specific due date with the Comptroller if you are uncertain.
Late Payment Penalties and Interest
Filing late or paying late results in penalties and interest charges that add up quickly:
- $50 penalty per late report, regardless of the amount owed.
- 5% penalty on the unpaid tax if payment is 1 to 30 days late.
- 10% penalty on the unpaid tax if payment is more than 30 days late.
- Interest accrues on unpaid tax starting 61 days after the due date.
These penalties and interest add up, so a business that consistently files late can face significant additional costs. Many businesses use online payment systems or auto-pay arrangements with the Comptroller to avoid missing deadlines.
How to File and Where to Pay
The Texas Comptroller accepts sales tax reports and payments online. You can file your report and pay your taxes through the Comptroller's online system, which you can reach from comptroller.texas.gov/taxes. Confirm the accepted payment methods on the Comptroller's site.
Keep detailed records of all sales, tax collected, and exemptions claimed. The Comptroller may request this documentation during an audit, and proper records are your strongest defense against audit adjustments.
Sales Tax Audits and What to Expect
The Comptroller's office conducts sales tax audits to ensure businesses are reporting accurately and remitting the correct amounts. An audit can be triggered by random selection, unusual patterns in your reports, customer complaints, or a change in your business structure.
Types of Audits
Desk audits are conducted remotely. The Comptroller requests documents and information by mail or email, and you respond without an in-person visit. These typically focus on a specific issue, such as a gap in reported sales.
Field audits involve a Comptroller representative visiting your business to review records on-site. A field audit is more comprehensive and may cover a longer period, up to the four-year limitations period. The auditor will review sales records, tax calculations, and your exemption documentation.
Audit Timeline and Resolution
After an audit closes, the Comptroller issues a report detailing any adjustments. If additional tax is owed, the Comptroller assesses it, and you have a right to appeal. An appeal must be filed within a set timeframe (check the Comptroller's website for the current appeal window). If you disagree with the audit findings, you can request a hearing before a hearing officer at the Comptroller's office.
How to Prepare for an Audit
Maintain organized records: sales invoices, receipts, exemption certificates from customers, and your monthly or quarterly tax filings. If you use a point-of-sale (POS) system, familiarize yourself with how to run reports that show total sales, tax collected, and by category. Have your sales tax permit, resale certificates, and any correspondence with the Comptroller easily available.
If you receive a notice of audit, do not ignore it. Contact the Comptroller's office promptly and ask which documents they need. If you are unsure how to respond, consider consulting a tax professional or CPA who is familiar with Texas sales tax.
Nexus and Resale Certificates
If you are a retailer, you may purchase goods for resale without paying sales tax, provided you hold a valid resale certificate (also called a resale exemption certificate). Your supplier uses this certificate as proof that you intend to resell the product, not use it.
However, if you use a product yourself or give it away, the exemption does not apply and tax is owed. Misusing resale certificates is a serious violation and can result in audit adjustments and penalties.
Key Takeaways and Compliance Checklist
- Verify the exact combined sales tax rate for each business location using the Comptroller's Sales Tax Rate Locator.
- Register for a permit with the Comptroller before collecting sales tax (permits are free).
- Note your assigned filing frequency (monthly, quarterly, or yearly) and mark all due dates on your calendar.
- Understand your economic nexus threshold if you operate as a remote seller: register once rolling 12-month revenue exceeds $500,000.
- File on time and pay in full to avoid penalties (starting at $50 per late report, plus 5% to 10% of unpaid tax).
- Keep detailed records of sales, tax collected, and exemptions for at least four years in case of audit.
- If you receive an audit notice, respond promptly and gather all requested documents.
