What Is Sales Tax? (Basics for Businesses)

Sales tax is a consumption tax imposed by state and local governments on the sale of goods and services. For businesses, it’s a critical responsibility to collect, report, and remit sales tax to the appropriate authorities. Here’s what Houston homeowners and small business owners need to know:

• Who Pays Sales Tax?
  Customers pay sales tax at the point of purchase, but businesses are responsible for collecting it and remitting it to the government.

• Sales Tax Rates in Texas (2025):
  Texas has a state sales tax rate of 6.25%, but local jurisdictions (like Houston) can add up to 2%, making the total rate 8.25%. For example, a $100 purchase in Houston would include $8.25 in sales tax.

• What’s Taxable?
  Most tangible goods (e.g., furniture, electronics) and some services (e.g., repairs, cleaning) are taxable. However, certain items like groceries and prescription drugs are exempt.

• Online Sales Tax:
  If your business sells online, you must collect sales tax if you have a physical presence (nexus) in Texas or meet economic nexus thresholds (e.g., $500,000 in annual sales).

How to Manage Sales Tax for Your Business

1. Register for a Sales Tax Permit:
   Apply through the Texas Comptroller’s office to legally collect sales tax.

2. Track Sales and Taxable Items:
   Use accounting software or tools to ensure accurate collection and reporting.

3. File and Remit Taxes:
   File returns monthly, quarterly, or annually, depending on your sales volume.

If you run a home-based business or sell products online, understanding sales tax ensures compliance and avoids penalties. Failing to remit sales tax can result in fines of up to 10% of the owed amount.

For property tax challenges, TaxLasso offers a streamlined solution. Unlike DIY methods that take hours or expensive legal firms, TaxLasso provides professional-level insights in just 5 minutes, saving you thousands while giving you full control over your tax filings.

Do You Need to Collect Sales Tax? (Nexus Explained)

Yes, you need to collect sales tax if you have a nexus in Texas. A nexus is a legal term that means a significant connection to a state, which requires you to comply with its tax laws. For Houston homeowners running a business, understanding nexus is critical to avoid penalties and ensure compliance.

What Creates a Nexus in Texas?

• Physical Presence: If your business has a physical location, employees, or inventory in Texas, you have a nexus.

• Economic Nexus: As of 2025, if your business generates over $500,000 in annual Texas sales, you must collect sales tax, even without a physical presence.

• Marketplace Facilitators: If you sell through platforms like Amazon or Etsy, they may handle sales tax for you, but you’re still responsible for reporting.

What Should Houston Homeowners Do?

1. Determine Your Nexus: Assess whether your business meets Texas’s physical or economic nexus criteria.

2. Register for a Sales Tax Permit: File with the Texas Comptroller’s office to collect and remit sales tax.

3. Set Up Tax Collection: Use tools like Shopify or QuickBooks to automate sales tax calculations.

How to Register for a Sales Tax Permit

If you’re starting or running a business in Houston, registering for a sales tax permit is a critical step to ensure compliance with Texas tax laws. Here’s how to get started:

1. Determine If You Need a Permit

You must register for a sales tax permit if you:

• Sell taxable goods or services in Texas.
• Operate an online business with sales to Texas customers.
• Have a physical presence (e.g., a store, office, or warehouse) in Texas.

2. Gather Required Information

Before registering, prepare the following:

• Business name, address, and contact details.
• Social Security Number (SSN) or Federal Employer Identification Number (FEIN).
• A description of your business activities.
• Banking information for tax payments.

3. Register Online with the Texas Comptroller

Visit the Texas Comptroller’s website and complete the online application. The process typically takes 15-20 minutes, and there’s no fee to register. Once approved, you’ll receive your permit within 2-3 weeks.

4. Understand Your Tax Obligations

As of 2025, Texas sales tax rates vary by location. In Houston, the combined state and local rate is 8.25%. You’ll need to:

• Collect sales tax from customers.

Sales Tax Rates and Calculation

Understanding sales tax rates and how to calculate them is critical for Houston homeowners running a business, whether online or in-person. Sales tax rates in Texas for 2025 are 6.25% at the state level, with local jurisdictions (like Houston) adding up to 2%, bringing the total sales tax rate to 8.25% in most areas.

Key Points to Know:

• State Sales Tax Rate: 6.25% (applies statewide).
• Local Sales Tax Rate: Up to 2% (varies by city/county).
• Total Sales Tax Rate in Houston: Typically 8.25%.

How to Calculate Sales Tax

1. Determine the total taxable sales amount.
2. Multiply the sales amount by the total sales tax rate (e.g., $100 x 8.25% = $8.25).
3. Add the tax to the sales amount for the total price ($100 + $8.25 = $108.25).

Special Considerations for Online Businesses

• If you sell online, you must collect sales tax based on the buyer’s location in Texas.
• Use a sales tax calculator or software to automate this process and ensure compliance.

Why Accurate Sales Tax Calculation Matters

Incorrect sales tax calculations can lead to penalties or audits. For example, undercharging by just 1% on $50,000 in sales could result in a $500 discrepancy, plus fines.
