To register for a Texas sales tax permit, go to the Texas Comptroller's eSystems portal (comptroller.texas.gov/taxes/permit), create an account, and complete the Texas Sales and Use Tax Permit application online. The process takes about 20–30 minutes. Most registrations are approved instantly or within 2–3 business days, and the permit is free. You need a permit before you begin collecting or remitting Texas sales tax — registering retroactively after you've already crossed the $500,000 economic nexus threshold is still better than not registering at all.

Do You Need to Register in Texas?

Texas uses a $500,000 economic nexus threshold — the highest in the country, five times the standard $100,000 used by most states. The threshold is revenue-only: transaction count plays no role.

You need to register for a Texas sales tax permit if:

• Your sales to Texas-based buyers exceeded $500,000 in the prior 12 months, OR
• You have a physical presence in Texas (warehouse, employee, office, trade show presence lasting more than 3 days), regardless of dollar amount

If your Texas sales are below $500,000 and you have no physical presence in the state, you have no Texas sales tax registration obligation.

Important: Texas uses a rolling 12-month lookback period. If you hit $500,000 in Texas sales at any point during the trailing 12 months — not just the calendar year — you have crossed the threshold.

What You Need Before You Start

Gather the following before beginning the eSystems application:

Business information:

• Legal business name (exactly as registered)
• Business address (physical location, not P.O. Box)
• Federal Employer Identification Number (EIN) — or SSN for sole proprietors
• Texas Secretary of State file number (if incorporated or LLC registered in Texas)
• NAICS code for your primary business activity (retail ecommerce = 454110)

Contact information:

• Primary contact name, phone number, and email
• Mailing address if different from business address

Business activity details:

• Date your business first made taxable sales to Texas buyers
• Estimated monthly Texas sales (the Comptroller uses this to assign your filing frequency)
• Types of products or services sold

You do not need to provide bank account information during registration. Texas doesn't debit your account for filings — you log in to pay each period.

Step-by-Step: Registering Through Texas eSystems

Step 1 — Go to the Texas Comptroller eSystems Portal

Navigate to: comptroller.texas.gov/taxes/permit

Select "New Applicant" and create a eSystems account with your email address. You'll receive a verification email. Confirm it before proceeding.

Step 2 — Start a New Tax Permit Application

After logging in, select "Apply for a New Permit or License." From the permit type list, select "Sales and Use Tax."

You will see the option to apply for multiple permit types in one application — if you also have a mixed beverage, hotel, or other Comptroller-managed obligation, you can add those here. For most ecommerce sellers, you only need the Sales and Use Tax permit.

Step 3 — Enter Business Information

Fill in:

• Legal entity type (sole proprietor, LLC, corporation, etc.)
• Business name and any DBA ("doing business as") names
• Federal EIN or SSN
• Principal place of business address
• Mailing address

Out-of-state sellers: Use your actual business address. You do not need a Texas address to obtain a Texas sales tax permit. Select "Out-of-State" as your location type when prompted.

Step 4 — Describe Your Business Activity

Select your primary NAICS code:

• 454110 — Electronic Shopping (most Shopify/ecommerce sellers)
• 453998 — All Other Miscellaneous Store Retailers (resellers not primarily ecommerce)
• 448140 — Family Clothing Stores (apparel-focused resellers)

Provide a brief description of what you sell and to whom. Keep it simple: "Online retail sales of [product category] to consumers via Shopify and marketplace platforms."

Enter your estimated monthly Texas taxable sales. Be honest here — the Comptroller assigns filing frequency (monthly vs. quarterly vs. annual) based on this estimate. Overestimating leads to more frequent filings; underestimating and then filing a large return can raise questions.

Monthly filing: Assigned if monthly Texas tax liability exceeds $500 Quarterly filing: Assigned if monthly liability is $100–$500 Annual filing: Assigned if monthly liability is under $100

Step 5 — Enter Your Texas Nexus Start Date

The application asks when your taxable sales in Texas began. This is the date you first made a sale to a Texas buyer, not the date you crossed the $500,000 threshold.

For sellers with historical Texas sales who are registering late: use the actual start date of your Texas sales activity. This establishes your "look-back" period for any back-filing discussions.

Step 6 — Review and Submit

Review every field. The most common errors:

• Wrong EIN (one transposed digit delays approval)
• Using a P.O. Box as the physical address (Texas requires a street address)
• Incorrect NAICS code

Submit the application. For most out-of-state online sellers with no Texas physical presence, approval is instant or within 1 business day. Complex applications (physical presence, existing audit history) may take 2–3 business days.

Step 7 — Receive Your Texas Sales Tax Permit

Your permit will be issued electronically through eSystems. Download and save it. You'll receive a Texas taxpayer number (an 11-digit number beginning with "1" or "3") — this is what you'll use to log in and file returns going forward.

You are not required to display your permit physically (Texas repealed that requirement), but keep it on file.

After Registration: Collecting Texas Sales Tax

The Texas state sales tax rate is 6.25%. Local taxing jurisdictions (cities, counties, transit authorities) may add up to 2% in additional district taxes, for a maximum combined rate of 8.25%.

As an out-of-state seller without a physical Texas location, you generally charge the rate applicable to the buyer's delivery address in Texas. Most ecommerce platforms (Shopify, WooCommerce) automatically apply the correct local rate once you've entered your Texas permit number in their tax settings.

In Shopify:

1. Go to Settings → Taxes and Duties
2. Under "United States," find Texas
3. Enter your Texas taxpayer number
4. Enable "Collect sales tax in Texas"
5. Shopify will apply origin-based or destination-based rates as appropriate

Texas Filing Deadlines

Texas sales tax returns are due on the 20th of the month following the close of the filing period:

| Filing Frequency | Period | Due Date | |-----------------|--------|----------| | Monthly | January | February 20 | | Monthly | February | March 20 | | Quarterly | Q1 (Jan–Mar) | April 20 | | Quarterly | Q2 (Apr–Jun) | July 20 | | Annual | Full year | January 20 |

If the 20th falls on a weekend or Texas state holiday, the deadline moves to the next business day.

Electronic Filing Discount: Texas offers a 0.5% discount on the tax due if you file and pay electronically — a small but automatic reward for online submission. Cap: $1,000 per period.

What If You're Already Past the $500,000 Threshold?

If your Texas sales have been over $500,000 for the past year and you haven't registered, don't panic — but act quickly.

Options:

1. Register now and begin filing. Texas does not require you to proactively volunteer prior uncollected tax when you simply register. You'll begin collecting and filing going forward.

2. Voluntary Disclosure Agreement (VDA). If you're concerned about back-liability for prior periods, Texas offers a VDA program through the Comptroller's office. A VDA typically limits your look-back period and may waive penalties. You should consult a tax professional before initiating a VDA.

The worst thing to do: Continue selling to Texas buyers above the threshold without registering. Texas purchases third-party sales data and conducts nexus audits. A Comptroller audit goes back much further than a self-initiated VDA.

Frequently Asked Questions

Q: Is a Texas sales tax permit free?
A: Yes. Texas does not charge a fee to obtain a sales tax permit. There is no renewal fee either — the permit remains valid as long as your business is active.

Q: How long does Texas sales tax registration take?
A: Most online applications for out-of-state sellers are approved instantly or within 1 business day. Complex situations (physical Texas location, prior audit history) may take 2–3 business days.

Q: Do I need a Texas address to get a Texas sales tax permit?
A: No. Out-of-state businesses register using their own business address. Select "Out-of-State" in the eSystems application.

Q: What's the Texas economic nexus threshold?
A: Texas uses a $500,000 threshold — revenue only, no transaction count minimum. This is one of the highest thresholds in the country. Most states use $100,000.

Q: When do I start collecting Texas sales tax after registering?
A: You must begin collecting sales tax from Texas buyers on the date your permit is issued, or on the date you crossed the threshold (whichever creates the obligation). Do not wait until your first filing is due.

Q: What if I make a mistake on the Texas registration application?
A: Log back into eSystems and submit an amended application, or contact the Texas Comptroller's office directly at 1-800-252-5555. Corrections are generally straightforward.

Q: What happens if I file Texas sales tax late?
A: Texas charges a penalty of 5% of tax due for filings received 1–30 days late, and 10% for filings more than 30 days late. Interest accrues at a rate set by the Comptroller (typically around 4–5% annually). Persistent late filing can result in permit revocation.
