  5. Receive Your Permit: Once approved, you’ll receive your permit via email or mail within 2-3 weeks.

Key Deadlines and Tips

  • Deadline: Register before making your first sale to avoid penalties.
  • Renewal: Sales tax permits do not expire, but you must update your information if your business changes.

Calculating Sales Tax Owed: A Step-by-Step Guide for Houston Homeowners

To calculate the sales tax owed, you need to determine the taxable sales amount and apply the appropriate tax rate. Here’s how to do it:

1. Determine Taxable Sales

  • Identify all taxable sales made during the reporting period (e.g., 2025 Q1).
  • Exemptions may apply, such as sales of certain groceries or medical supplies.

2. Apply the Correct Tax Rate

  • Houston’s combined sales tax rate for 2025 is 8.25% (6.25% state + 2% local).

Avoiding Penalties & Correcting Errors in Sales Tax Filing

To avoid penalties and correct errors in sales tax filing, Houston homeowners must act promptly and accurately. Late or incorrect filings can result in fines, interest charges, and audits. Here’s how to stay compliant and fix mistakes:

Avoiding Penalties

Correcting Errors
