Who must collect sales tax in Austin?
You have nexus and must collect if any of these apply:
- You operate a physical location in Austin or surrounding jurisdictions
- You have an employee or contractor based in Texas
- You store inventory at an FBA warehouse in Texas
- Your Texas sales exceed the state's economic nexus threshold (typically $100,000 or 200 transactions)
Destination-based vs origin-based
Austin 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 Austin, the destination rate applies.
Special Austin 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 Austin sales tax is filed through the Texas state authority, which then distributes local portions to Austin 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.
Common pitfalls in Austin
- Using your business's ZIP code rate when you should use the customer's (destination-based states)
