Who must collect sales tax in San Antonio?
You have nexus and must collect if any of these apply:
- You operate a physical location in San Antonio or surrounding jurisdictions

- Your Texas sales exceed the state's economic nexus threshold (typically $100,000 or 200 transactions)
Destination-based vs origin-based
San Antonio follows origin-based sourcing for in-state sales. You charge the rate at your business location, not the customer's.
For out-of-state sales shipped to San Antonio, the destination rate applies.
Special San Antonio taxes
In addition to general sales tax, be aware of:
- Liquor/tobacco: excise taxes on top of sales tax
- Vehicle/fuel: separate regimes entirely
Filing: state vs local
Most San Antonio sales tax is filed through the Texas state authority, which then distributes local portions to San Antonio and surrounding jurisdictions. You file one return covering state + all local rates.
Filing frequency
Assigned by the state based on expected liability:
- Monthly: larger collectors
- Quarterly: mid-size
- Annually: smallest sellers
Returns are typically due by the 20th of the month following the period. Missing a deadline: ~10% penalty + interest.
