District of Columbia Sales Tax Calculator (2026) — Add or Reverse Tax
District of Columbia's combined sales tax rate is 6.00% (6.00% state). Use the calculator below to add District of Columbia sales tax to a price, or reverse a tax-included total to find the pre-tax price and exact tax amount.
How to use this calculator:
- Adding tax — enter a pre-tax price, pick "Add tax to price," and the calculator applies the District of Columbia rate to show the tax amount and final total.
- Reversing (extracting) tax — enter a total that already includes tax, pick "Extract tax from total," and the calculator divides by 1 + the rate to isolate the pre-tax price and the exact tax paid.
- Pick the rate that matches your situation: the average combined rate is a good statewide estimate, but the state-only or maximum-local rate is more precise if you know the exact city or county.

Why Reverse Sales Tax Calculation Matters
Receipts, invoices, and marketplace payouts usually show only the tax-included total — not the pre-tax price. Reversing the calculation matters for bookkeeping (separating revenue from tax collected), expense reports (reimbursing only the pre-tax cost), and price comparisons (checking what an item actually costs before District of Columbia's tax is applied). Because dividing by (1 + rate) is not the same as simply subtracting the rate from the total, doing this by hand is a common source of errors — the calculator above handles it exactly.
History & Rate Breakdown
District of Columbia's modern sales tax framework reflects decades of legislative adjustment, layering state and local levies to reach today's combined rate of 6.00%. As with most states, the exact history of rate changes is set by the legislature and administered at the state level.
The District's 6.00% general sales tax rate applies uniformly citywide (DC has no counties), but several categories carry their own special rates set independently by the DC Council: restaurant meals and prepared food at 10%, hotel stays at 15.95%, commercial parking at 18%, and soft drinks at 8%. Alcohol sold for off-premises consumption is taxed at 10.25%.
Where the Money Goes
DC's sales tax revenue — especially the elevated rates on hotels, restaurants, and parking — leans heavily on tourism and the daytime commuter workforce, alongside the District's income tax revenue, to fund municipal services.
Business Use Case: Registering & Collecting District of Columbia Sales Tax
A hotel operator in DC must apply the special 15.95% lodging rate rather than the general 6% rate, while a food truck a block away applies the 10% prepared-food rate — a reminder that DC's category-specific rates matter as much as the general rate for correctly pricing a sale.

The state sales tax rate plus any applicable local (city, county, or special district) rates — the actual rate charged at checkout in a given location.

The process of working backward from a tax-included total to find the pre-tax price and the exact tax amount, using total ÷ (1 + rate) = pre-tax price.

A sales threshold (in dollars, transaction count, or both) that obligates an out-of-state seller to collect and remit sales tax even without a physical presence in the state.

A platform (e.g. Amazon, Etsy, eBay) that collects and remits sales tax on behalf of third-party sellers under most states’ marketplace facilitator laws.
Real-World Example
A $500.00 purchase in District of Columbia at the average combined rate of 6.00%:
