Do you need to collect sales tax in District of Columbia?
You have a duty to collect once you have nexus: physical presence (inventory, staff, an office) or economic nexus from crossing $100,000 in sales or 200 transactions over previous or current calendar year. District of Columbia still counts transactions: crossing 200 transactions creates nexus even on modest revenue.
The District of Columbia rate
The general sales tax rate is 6.0% through September 30, 2026. The previously planned 6.5% rate (effective Oct 1, 2025) was repealed by the Sales Tax Increase Delay Amendment Act of 2025.
Marketplace and direct sales
Marketplaces like Amazon collect District of Columbia tax for you, but those sales still count toward your threshold. Direct sales on your own store you collect yourself.
Filing and zero returns
Once registered, District of Columbia requires a return every assigned period even when you owe $0 — miss one and you can face penalties. Annual if average monthly sales tax liability is $200 or less (due January 20); Quarterly if liability is $201-$1,200 per period (due 20th day after quarter-end); Monthly if liability exceeds $1,200 per month (due 20th of following month).
When you can cancel
If your District of Columbia returns are mostly $0, you may be over-registered. Canceling your DC sales tax registration makes sense if your sales into the District have dropped below both the $100,000 and 200-transaction thresholds for the current and prior calendar year, eliminating your economic nexus. The cancellation process is handled online through MyTax.DC.gov — log in, go to your Account Summary page, and submit a web request with the closure date and explanation.
