Texas Sales Tax: Rates, Rules & Compliance Guide

‍

Texas charges a 6.25% state sales tax rate. Local taxing jurisdictions can layer on up to another 2%, bringing the maximum combined rate to 8.25%. Unlike a lot of states, Texas taxes both SaaS and many digital goods, which catches a lot of tech and software companies off guard.

This Texas sales tax guide covers everything you need to know: what's taxable, when you have nexus, how to register, how to calculate the right rate, how to file, and how to remit. And at the end, we'll show you how Sphere handles all of it automatically for you.

What Is Taxable in Texas

SaaS and Data Processing Services

SaaS is generally taxable in Texas for both B2B and B2C sales. The state classifies SaaS as a taxable "data processing service.”

But it’s important to note that Texas only taxes 80% of the SaaS charge. The remaining 20% is statutorily exempt under the data processing carve-out. This applies whether your customer is a business or a consumer.

So if you sell a $100 SaaS subscription to a Texas customer, you’d collect sales tax on $80 of it rather than the full $100.

Digital Goods

Many digital goods are taxable in Texas. This includes downloaded software, apps, and digital media. However, media streaming services with no downloaded component are generally not taxable. 

Some categories do have carve-outs or exemptions. If you're selling digital books, music, or other specific digital content formats, verify your product's tax treatment with a qualified tax advisor before assuming it's taxable. Texas's rules on digital goods can be product-specific.

Tangible Personal Property (TPP)

Most tangible personal property sold at retail is taxable in Texas. There are a few important exceptions:

• Groceries - food for home consumption is exempt
• Prescription drugs - generally exempt
• Certain medical devices - may be exempt depending on the device

If you sell physical goods into Texas, the general rule is that it’s taxable unless you can point to a specific exemption.

Monitoring — When Texas Sales Tax Applies to Your Business

Economic Nexus

Texas's economic nexus threshold is $500,000 in total Texas sales (taxable and exempt combined) in the prior or current 12-month period.

A few things worth noting:

• Both taxable and exempt retail sales count toward the sales threshold
• There is no transaction-count threshold in Texas. The threshold is revenue only
• Once you cross the threshold, you must begin collecting no later than the first day of the fourth month after you cross it

Physical Nexus

Any physical presence in Texas creates nexus. This includes:

• Offices or storefronts
• Employees or contractors based in Texas
• Warehouses or fulfillment centers
• Inventory stored in the state

Remote employees working from Texas can also trigger physical nexus and the need for tax collection, even if your company doesn't have a formal office there.

Sphere monitors your Texas sales exposure in real time and alerts you when you're approaching or have crossed nexus thresholds in Texas and every other jurisdiction where you sell.

Registration — How to Get a Texas Sales Tax Permit

How to Register

Register for a Texas sales tax permit through the Texas Comptroller's online portal. Here's what the process looks like whether you are in Texas or out-of-state:

1. Create a login at the Texas Comptroller's eSystems portal
2. Complete the online application for a Sales and Use Tax Permit
3. Provide basic business info: 
   
   1. Ownership details
   2. NAICS code
   3. Social Security number(s) or EIN

The permit application itself is free. However, the Comptroller may require a security bond in some cases. These are typically for businesses with high anticipated sales volume or in specific industries.

Fees and Timing

After applying, it generally takes 2–3 weeks to receive your permit. During that window, you'll get your TX Taxpayer Number, which identifies your account. Your WebFile ID (what you'll use to actually file returns) then arrives separately by mail.

Don't plan to file your first return until that WebFile ID shows up.

Note that Sphere manages Texas sales tax registration on your behalf, including tracking your permit status so you're ready to file the moment your credentials arrive.

Calculation — Getting the Right Tax Rate

State vs. Local Rates

Texas has a straightforward layered rate structure:

• State rate: 6.25%
• Local rate: up to 2% added by cities, counties, transit districts, and special purpose districts
• Maximum combined rate: 8.25%

Most major Texas cities like Houston, Dallas, Austin, and San Antonio set sales tax at the maximum 8.25% rate. Smaller jurisdictions may be lower. The rate that applies for a remote seller when making an e-commerce or online sale is based on where your customer is located (i.e. destination sourcing). Note that sellers within the state of Texas making an online sale to a buyer in Texas should use their own sales tax rate (i.e. origin sourcing.) 

SaaS Rate Calculation

Because SaaS is only taxed at 80% of the total, it’s important to categorize SaaS transactions and calculate them at the right rate. To do this:

1. Determine the combined sales tax rate for your customer's location (state + local)
2. Apply that rate to 80% of the transaction value
3. Count the remaining 20% as exempt and don't collect tax on it

Example: You sell a $500/month SaaS subscription to a customer in Austin (8.25% combined rate):

• Taxable portion: $500 × 80% = $400
• Tax owed: $400 × 8.25% = $33

The remaining 20% ($100) is tax exempt.

Single Local Use Sales Tax Option

Texas allows eligible remote sellers to simplify local tax collection by electing a single, statewide local use tax rate of 1.75% instead of calculating the exact local rate for each jurisdiction.

If you elect this method:

• You still collect the 6.25% state rate
• You apply a flat 1.75% local rate to all Texas sales
• Your total collected rate becomes 8.0%

This can significantly reduce complexity for businesses making high volumes of Texas sales.

However:

• You must formally elect this option with the Texas Comptroller
• Once elected, you must apply it consistently
• It may result in over- or under-collection compared to the exact local rate, a factor some customers may notice

Using the Texas Comptroller Rate Locator

The Texas Comptroller provides a Sales Tax Rate Locator tool (i.e. a Texas sales tax calculator) to look up the exact combined rate by ZIP code or address. Local rates can change, so it's worth checking if you're ever unsure about a specific location.

Note that Sphere calculates the correct Texas sales tax rate on every transaction automatically, including the 80/20 SaaS split. Sphere then applies the right local rate based on your customer's address so you collect the right amount of sales tax, every time, no matter what you’re selling.

Filing — Texas Sales Tax Returns

Filing via Webfile

Texas sales tax returns are filed through the Comptroller's Webfile portal. Returns are due on the 20th of the month following the end of the tax period. So if you’re required to file monthly, you would pay your January sales tax by February 20th.

Businesses that paid $10,000 or more in Texas sales tax in the prior fiscal year are required to file electronically. If you're below that threshold, you can still file electronically or file by paper. Electronic filing is encouraged. Sphere can automate filing, eliminating manual Texas sales tax return preparation. 

Filing Frequency

The Texas Comptroller assigns your filing frequency when you register, based on your estimated tax liability:

• Monthly - you owe more than $1,500 in state tax per quarter
• Quarterly - you owe less than $1,500 in state tax per quarter
• Annually - you owe less than $1,000 in state tax per year

You can request a change in filing frequency if your sales volume changes significantly. 

Texas allows a 0.5% discount on the tax amount you timely report and pay. Businesses that prepay sales tax can earn an additional 1.25% discount on top of that.

Penalties for Late Filing

Missing a Texas sales tax deadline results in penalties and interest. Here's how the penalties work:

• $50 flat penalty on each return filed after the due date
• 5% penalty if tax is paid 1–30 days late
• 10% penalty if tax is paid more than 30 days late
• Additional 10% penalty (total of 20%) if you fail to pay after receiving a Notice of Tax Due
• Interest begins accruing on unpaid balances starting 61 days after the original due date

Sphere can automate filing directly through Webfile, so late filings and the penalties are no longer a risk.

Remittance — Paying Texas Sales Tax

Standard Remittance via Webfile

Once you file your return through Webfile, payment is made after via ACH debit. You provide your US bank account details, and the Comptroller's office debits the amount owed.

It's straightforward for businesses with US banking relationships. The payment is processed alongside your filed return.

Remittance for Foreign Businesses

If your business doesn't have a US bank account, you can't use the standard ACH debit process. This is a common roadblock for international businesses selling into Texas.

Sphere's embedded remittance platform handles Texas tax payments for businesses without US banking access with no US bank account required.
