What Is Economic Nexus in Washington, D.C.?
Economic nexus allows D.C. to require an out-of-state business to collect and remit sales tax based on its level of sales into the District, even if it doesn’t have a physical presence there.
For remote sellers, the key figure to monitor is $100,000 in qualifying gross receipts from sales delivered into D.C. Businesses below the economic nexus threshold should still consider whether they have physical nexus.
What Is the Economic Nexus Threshold in D.C.?
A remote seller generally establishes economic nexus when its qualifying gross receipts from sales into D.C. exceed $100,000 during the previous or current calendar year. D.C. previously had an alternative 200-transaction threshold, but this was repealed effective January 1, 2021.
Remote sellers therefore need to focus on their sales revenue rather than the number of individual transactions.
What Sales Count Toward D.C.’s $100,000 Threshold?
D.C.’s economic nexus threshold is based on qualifying gross receipts from sales into the District.
For ecommerce businesses, this can include sales through:
- Shopify
- WooCommerce
- Your own ecommerce website
- Marketplace facilitators
- Other sales channels
Marketplace sales are important because they can count when determining whether the economic nexus threshold has been exceeded, even though the marketplace may be responsible for collecting the tax.
Do Amazon Sales Count Toward D.C. Economic Nexus?
Yes, sales made through marketplace facilitators such as Amazon generally count toward the $100,000 economic nexus threshold.
However, qualifying marketplace facilitators are generally responsible for collecting and remitting D.C. sales tax on the transactions they facilitate. For example, if you have $80,000 of Amazon sales and $30,000 of Shopify sales into D.C., your combined sales of $110,000 can cause you to exceed the economic nexus threshold.
You would generally be responsible for collecting tax on your direct sales, while Amazon handles the marketplace transactions.
Can You Have D.C. Nexus Below $100,000?
Yes, physical presence can create sales tax nexus independently of the economic nexus threshold.
Physical nexus can potentially include:
- An office or business location
- Employees working in D.C.
- Inventory stored in the District
- A warehouse or fulfilment location
- Certain other in-District business activities
The $100,000 economic threshold should therefore not be the only factor considered when determining your obligations.
How Does Washington, D.C. Sales Tax Work?
Washington, D.C.’s general sales tax rate is 6%. Unlike states with extensive city and county sales taxes, D.C. does not have multiple local jurisdictions adding separate general sales tax rates.
However, certain products and services are subject to different rates, so businesses should still confirm the correct tax treatment of what they sell.
What Should You Do After Crossing the D.C. Nexus Threshold?
If your qualifying D.C. sales exceed $100,000:
- Confirm when the threshold was reached.
- Review your marketplace and direct sales.
- Check whether you already have physical nexus.
- Register with the D.C. Office of Tax and Revenue.
- Configure your ecommerce platform to collect the appropriate tax.
- Begin filing and remitting sales tax as required.
Businesses should monitor their D.C. sales throughout the year rather than waiting until year-end.
Washington, D.C. Economic Nexus Examples
Shopify seller:
A remote business has $125,000 of qualifying Shopify sales into D.C. It exceeds the economic nexus threshold and should review its registration requirements.
Smaller high-volume seller:
A business completes 500 D.C. transactions worth $60,000. The number of transactions alone doesn’t create economic nexus because D.C. no longer has a transaction-count threshold.
Amazon and Shopify seller:
A business has $75,000 of Amazon sales and $40,000 of direct Shopify sales into D.C. Its combined sales exceed $100,000, meaning it can meet the economic nexus threshold. The marketplace generally handles tax on its transactions, while the seller is responsible for its direct sales.
What If You Should Have Registered Previously?
If you established D.C. nexus in a previous period but didn’t register, you could have outstanding sales tax liabilities, together with applicable penalties and interest.
Depending on your circumstances, a Voluntary Disclosure Agreement (VDA) may provide a way to resolve historical liabilities and potentially receive benefits such as penalty relief or a limited lookback period.
It’s important to investigate your options before being contacted by the D.C. Office of Tax and Revenue.
