Do You Need a State Sales Tax Number?

If you’re a Houston homeowner selling goods or services, you likely need a state sales tax number. Also known as a sales tax permit, this number is required by the Texas Comptroller if you’re conducting business and collecting sales tax. Here’s what you need to know:

When You Need a State Sales Tax Number

• Selling taxable goods or services: If you sell items like furniture, electronics, or home repair services, you must collect and remit sales tax to the state.
• Operating a home-based business: Even small businesses, like Etsy shops or freelance consulting, may require a sales tax number if you meet Texas’s $1,000 annual sales threshold.
• Hosting events or pop-ups: Temporary sales events in Houston still require a permit if you’re selling taxable items.

How to Get Your Sales Tax Number

1. Apply online: Visit the Texas Comptroller’s website and complete the application. It’s free and typically processed within 2-3 business days.
2. Gather required documents: You’ll need your Social Security Number (or EIN), business details, and estimated monthly sales.
3. Start collecting tax: Once approved, you’ll receive your sales tax number and can begin collecting sales tax at the current Texas rate of 6.25% (8.25% in Houston, including local taxes).

Why This Matters for Houston Homeowners

• Avoid penalties: Operating without a sales tax number can result in fines up to $500 per violation in 2025.
• Simplify tax filing: Your sales tax number ensures you’re compliant and makes filing quarterly tax returns easier.

If you’re also dealing with property tax challenges, like high valuations or protests, consider using TaxLasso.

State Sales Tax Number vs. EIN vs. Seller's Permit

Understanding the difference between a state sales tax number, EIN, and seller's permit is crucial for Houston homeowners running a business or selling goods. Here's a breakdown:

Key Differences at a Glance

• State Sales Tax Number: Required to collect and remit sales tax on taxable goods and services in Texas. If you sell products or services subject to sales tax, you must register for this number with the Texas Comptroller.
• EIN (Employer Identification Number): Issued by the IRS, this is used for federal tax purposes, such as hiring employees or filing business taxes. It’s not specific to sales tax.
• Seller's Permit: In Texas, this term is often used interchangeably with a state sales tax number. It authorizes you to collect sales tax and is required for businesses selling taxable items.

Why This Matters for Houston Homeowners

• If you’re selling goods (e.g., furniture, home decor, or handmade items) from your Houston home, you likely need a state sales tax number or seller's permit to comply with Texas tax laws.
• As of 2025, Texas requires businesses to file sales tax returns quarterly, even if no sales occurred. Missing deadlines can result in fines.
• An EIN is only necessary if you have employees or operate as a corporation/LLC.

State-by-State Requirements

Understanding state-by-state requirements for obtaining a sales tax number is critical for Houston homeowners operating a business. Each state has its own rules, fees, and processes, making compliance essential to avoid penalties.

Key State-by-State Requirements

• Texas: In Texas, you must apply for a sales tax permit through the Texas Comptroller’s office. The process is free, and you can complete it online.

  • Louisiana: $50 fee, 10-15 business days processing.

  • Arkansas: $50 fee, 7-10 business days processing.
