What is the washington d.c. sales tax calculator?
In short
In Washington D.C., the state sales-tax rate is 6.5% (average combined 6.5% with local add-ons). Expect $6.50 of state tax on a $100 item — $106.50 all in. As a single jurisdiction, Washington D.C. has no local add-ons — one district-wide rate, with higher special rates on meals, alcohol and hotels. One rate covers the entire District.
Enter a price and this Washington D.C. tool returns the sales tax and total at the 6.5% state base rate, with a field to swap in your local combined rate. The District has no local add-on taxes — it is a single jurisdiction, so one rate applies everywhere in DC.

Common use cases
- Estimating the out-the-door cost of a Washington D.C. purchase before you buy
- Comparing tax on a big-ticket item between Washington (6.5%) and a lower-rate locality
- Seeing why your receipt differs from the 6.5% headline — dC uses tiered special rates rather than a flat one: 10% on restaurant meals, 10.25% on liquor and rental cars, and roughly 14.95% on hotels.
- groceries are exempt but prepared food is taxed at 10%, so the same sandwich can be tax-free cold or taxed at 10% when heated
Limitations & assumptions
- This tool uses the Washington D.C. state base rate (6.5%); combined local rates vary — no local add-ons — one district-wide rate, with higher special rates on meals, alcohol and hotels.
- Grocery food for home preparation is fully exempt, while prepared and restaurant food is taxed at a higher 10% meals rate.
- Rates change: The general sales-tax rate rose from 6.0% to 6.5% effective Oct 1, 2025, with a further increase to 7.0% scheduled for Oct 1, 2026 under the 2024 Budget Support Act. Confirm with the DC Office of Tax and Revenue before filing.
