Who must register for Texas sales tax
You must register for a Texas Sales Tax Permit if your business has a sales tax nexus in the state. This usually applies when a business:
- Exceeds the economic nexus threshold of $500,000 in annual sales to Texas customers in the current or previous calendar year, or;
- Has a physical presence in Texas, such as an office, employee, warehouse, or inventory stored in the state.
Texas's $500,000 threshold is one of the highest in the United States, equal to California's threshold. Many smaller online businesses do not reach it and therefore have no Texas sales tax obligation.
Once you exceed the threshold, you should register before making further taxable sales in Texas. If you're unsure whether your business has nexus, see the Texas Sales Tax Guide for a broader explanation of Texas nexus rules.
