How to File Texas Sales Tax Cheap: A Guide for Small Businesses

Last updated: July 2026 | Reading time: ~7 minutes

The direct answer: The cheapest way to file Texas sales tax is Taxero at $19.99 per filing — no subscription, no minimum commitment. If you file quarterly, that's $79.96/year. Alternatively, you can file manually through the Texas Comptroller's eSystems portal for free, but plan to spend 1–2 hours per return.

Texas is unique among major e-commerce states: its economic nexus threshold is $500,000 in annual sales — five times higher than most states. That means most small Shopify, Etsy, and Amazon sellers in Texas don't have nexus at all. But if you cross that threshold, you need to file correctly — and cheaply.

Does My Small Business Have Texas Sales Tax Nexus?

Texas nexus can be triggered in two ways:

Economic Nexus (Most Common for Online Sellers)

Texas enacted economic nexus following the South Dakota v. Wayfair Supreme Court decision in 2018. The Texas threshold is:

$500,000 in total Texas sales in the prior 12-month period

This is the highest economic nexus threshold in the country. California's threshold is $500,000 as well, but most states are $100,000. If your total annual revenue is under $500,000, you almost certainly do not have Texas economic nexus and do not need to file Texas sales tax returns.

Physical Nexus

Physical nexus applies regardless of your sales volume. You have Texas physical nexus if you have:

• An office, store, or warehouse in Texas
• Employees or contractors located in Texas
• Inventory stored in Texas (including Amazon FBA warehouses in Texas — DFW area has major Amazon fulfillment centers)
• A trade show or sales event in Texas

If you sell on Amazon FBA and your inventory is stored in a Texas warehouse, you have Texas nexus regardless of your sales volume.

Texas Marketplace Facilitator Rule

Amazon, Shopify's Shop channel, Etsy, eBay, and other major platforms are classified as marketplace facilitators in Texas. This means they collect and remit Texas sales tax on your behalf for sales made through their platforms.

However, this does NOT exempt you from filing a return if you have nexus. If you also sell through your own website or other non-marketplace channels in addition to Amazon, you need to file returns for those sales.

Texas Sales Tax Rate: What Are You Collecting?

Texas has a state rate of 6.25% plus local rates up to 2%, for a combined maximum of 8.25% in most cities and counties.

Common Texas sales tax rates:

• Dallas: 8.25%
• Houston: 8.25%
• Austin: 8.25%
• San Antonio: 8.25%
• Rural unincorporated areas: 6.25% (state only)

Texas has one of the simpler rate structures for e-commerce sellers — the maximum rate of 8.25% applies to most urban destinations, and most products are taxable at the same rate. Texas does not have some states' complex product-level exemption rules for clothing or groceries in the same way.

How Often Do You File Texas Sales Tax?

Texas assigns filing frequency based on your annual sales tax liability:

| Annual Tax Liability | Filing Frequency | Due Date | |---------------------|-----------------|----------| | Over $10,000/month | Monthly | 20th of following month | | $500 – $10,000/month | Quarterly | 20th of month after quarter end | | Under $500/month | Annual | January 20 |

Quarterly deadlines for Texas:

• Q1 (Jan–Mar): Due April 20
• Q2 (Apr–Jun): Due July 20
• Q3 (Jul–Sep): Due October 20
• Q4 (Oct–Dec): Due January 20

Most small businesses with Texas nexus file quarterly. Missing a deadline costs you: Texas charges a 5% penalty for returns filed less than 30 days late and a 10% penalty for returns filed more than 30 days late, plus interest.

How to File Texas Sales Tax for Free (Manual Method)

Texas provides a free online filing system through the Comptroller's eSystems portal. To file manually:

1. Go to mycpa.cpa.state.tx.us
2. Log in with your Texas Taxpayer ID number
3. Select "File a Return" and choose the period
4. Enter:
   • Total Texas sales for the period
   • Taxable sales (after exemptions)
   • Tax collected from customers
   • Tax due to the state
5. Pay via ACH or card
6. Save the confirmation

Manual filing is free but requires you to calculate the correct numbers from your sales records. If you sell on multiple platforms, you'll need to aggregate transaction data across all channels to get accurate state totals.

Estimated time: 1–2 hours per return for sellers with clean records and 1–3 platforms.

Texas Sales Tax vs. Hiring a CPA

A CPA or accountant will typically charge $100–$300 per return for Texas sales tax preparation and filing. For a quarterly filer, that's $400–$1,200/year for Texas alone.

For most small businesses with straightforward sales (consistent product types, 1–2 platforms, no complex exemptions), a CPA is overkill for routine quarterly filings. Taxero at $79.96/year for Texas handles the same task.

When to use a CPA instead:

• You have complex exemption situations (manufacturing, resale, agricultural)
• You have back years to catch up (Taxero handles this too, but a CPA can also negotiate with the Comptroller)
• You're facing a Texas audit
• You have employees, multiple locations, or complex business structures in Texas

Texas-Specific Sales Tax Rules Worth Knowing

What Is Taxable in Texas?

Texas taxes most tangible personal property (physical goods). Key exemptions:

• Groceries: Most food for home consumption is exempt (exceptions: candy, soft drinks, prepared food)
• Prescription drugs and medical devices: Exempt
• Agricultural equipment: Various exemptions for qualifying farm equipment
• Manufacturing: Raw materials and goods directly used in production have exemptions

For most e-commerce sellers selling general merchandise, virtually everything you sell is taxable in Texas.

Digital Goods in Texas

Texas does tax certain digital goods, including:

• Downloaded music, movies, and video games
• Software sold or delivered digitally
• Streaming subscriptions may be taxable depending on structure

If you sell digital products, verify taxability with the Texas Comptroller's taxability rules.

Texas Resale Certificate

If you buy goods for resale and want to avoid paying sales tax on your inventory purchases in Texas, you need a Texas Sales and Use Tax Exemption Certificate (Form 01-339). This is for B2B purchases, not consumer sales.

What Happens If You Miss a Texas Sales Tax Filing?

Texas enforcement of sales tax compliance has increased significantly in recent years. The Comptroller's office actively cross-references marketplace seller data, 1099-K filings, and federal business registration data.

Consequences of missing Texas filings:

1. 5% penalty — Returns filed less than 30 days late
2. 10% penalty — Returns filed more than 30 days late
3. Interest — Prime rate plus 1%, compounded monthly
4. Formal assessment — Texas will estimate your liability if you don't file and send a formal assessment notice
5. Permit suspension — Repeat non-filers can have their Texas sales tax permit suspended

The Texas Comptroller offers a voluntary disclosure program for sellers who have nexus but have not yet registered. This can cap the lookback period and waive penalties. Contact the Comptroller's office directly or apply through the MTC's National Nexus Program.

Frequently Asked Questions

Does my small business need to file Texas sales tax? Only if you have Texas nexus. For online sellers, economic nexus triggers at $500,000 in annual Texas sales — the highest threshold in the country. Most small businesses don't have Texas economic nexus. You also have nexus if you store inventory in Texas (including Amazon FBA warehouses in Texas).

What is the Texas sales tax rate for online sellers? The state rate is 6.25%. With local rates, most Texas cities charge 8.25% total. For sales shipped to customers in unincorporated rural areas, only the 6.25% state rate applies.

When is Texas sales tax due for quarterly filers? Texas quarterly returns are due on the 20th of the month following the end of each quarter: April 20 (Q1), July 20 (Q2), October 20 (Q3), January 20 (Q4).

Can I file Texas sales tax online? Yes. The Texas Comptroller's eSystems portal at mycpa.cpa.state.tx.us allows online filing and payment. Taxero also files electronically on your behalf for $19.99.

What is the cheapest way to file Texas sales tax? Manual filing through the Texas Comptroller's eSystems is free if you have the time (1–2 hours per return). Taxero files for $19.99/return, which is the cheapest fully automated option. A CPA will charge $100–$300/return.

Does Amazon pay Texas sales tax for me? Amazon pays the tax on sales made through Amazon.com (marketplace facilitator). If you also sell through your own Shopify store or website to Texas customers, you need to file returns for those sales separately — Amazon's remittance doesn't cover your off-Amazon channels.

What if I have nexus in Texas but haven't registered? Register immediately through the Texas Comptroller's office, then file all back returns from when your nexus began. Consider Texas's voluntary disclosure program if you have significant back-tax exposure — it can cap penalties and sometimes waive them.
