How much is sales tax in District of Columbia?
DC charges a flat 6% sales tax that applies uniformly across the entire district. There's no difference between Washington proper and surrounding areas—the rate is constant everywhere. While 282 taxing jurisdictions are recorded, they all adhere to the same 6% rate, so you'll get consistent taxation from southeast to northwest DC.
Because DC has only one rate, you don't need to look up the exact rate by address. However, Sefro's API can verify what products and services are taxable in DC, since the tax applies to a specific set of goods and digital products, not everything. For accuracy, it's wise to confirm what counts as taxable in your situation.
What's taxed and what's exempt in District of Columbia
Groceries are taxed in DC at the 6% rate, so you'll pay sales tax on your food shopping. Clothing is also taxable at the same 6% rate. This is different from some states, so if you're new to DC or comparing across jurisdictions, remember that both groceries and apparel are taxable here.
SaaS and digital software are taxable in DC at 6%. Prescription medicines are exempt, which helps offset healthcare costs. Restaurant meals and prepared foods are generally taxed, so budget for that when dining out or buying takeout in DC.
Do you have to collect District of Columbia sales tax? (Economic nexus)
Like most states after the 2018 Wayfair decision, District of Columbia requires out-of-state sellers to register and collect once their sales into the state cross an economic-nexus threshold. That line is commonly around $100,000 of sales into District of Columbia per year, and some states also count a number of separate transactions — but the exact figure, and whether the transaction count still applies, change from time to time. Confirm District of Columbia's current threshold before you rely on it.
If you sell into District of Columbia from out of state, the practical question is whether you've crossed that line. Watching your sales into each state is how you know when you're on the hook — and it's the kind of thing that's easy to miss until a notice shows up.
