Who must collect sales tax in Indianapolis?
You have nexus and must collect if any of these apply:
- You operate a physical location in Indianapolis or surrounding jurisdictions
- You have an employee or contractor based in Indiana
- You store inventory at an FBA warehouse in Indiana
- Your Indiana sales exceed the state's economic nexus threshold (typically $100,000 or 200 transactions)
Destination-based vs origin-based
Indianapolis is in a destination-based state — you charge the rate at the customer's delivery address, not yours.
This matters for online and multi-location businesses: tracking dozens of local rates becomes a pain without software.
Special Indianapolis 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 Indianapolis sales tax is filed through the Indiana state authority, which then distributes local portions to Indianapolis 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 Indianapolis
- Using your business's ZIP code rate when you should use the customer's (destination-based states)
- Missing local-only taxes like hotel/meals
- Not knowing about Indianapolis's special industry rules
- Failing to track local rate changes (some local portions change quarterly)
