Washington DC has a flat 6% general sales tax with no additional local taxes. You must register and collect sales tax in DC if your annual sales exceed $100,000 or you make 200 or more separate transactions. SaaS and digital products are taxable in Washington DC.
Whether you sell software, physical goods, or digital content into the District, this guide covers everything you need to know — rates, taxability, nexus rules, registration, and filing.
What is sales tax in Washington DC?
Washington DC imposes a sales tax on most retail sales of tangible personal property and many services within the District. Unlike US states, Washington DC has no municipalities or counties within it — the District itself is the single jurisdiction, so one set of rules applies uniformly.
Washington DC uses a destination-based sales tax system, meaning you charge tax based on where the buyer is located. The general rate is a flat 6%, though certain categories carry significantly higher rates (see the rates section below).
What is taxable in Washington DC?
Most sales of tangible personal property are taxable in Washington DC. The District also taxes many services, including personal, professional, and digital services. Always verify with the Office of Tax and Revenue for specific guidance on your product or service category.
Digital products and SaaS taxability in Washington DC
Washington DC taxes SaaS (Software as a Service) at the general 6% rate. The District treats cloud-based software delivered over the internet as a taxable service, regardless of whether the customer is a business or an individual. There is no general B2B exemption for SaaS in DC.
Downloaded digital products — including software, e-books, music, and video — are also generally taxable in Washington DC.
Sales tax on shipping charges in Washington DC
Shipping charges in Washington DC are generally taxable when the goods being delivered are themselves subject to tax. If the shipped item is exempt, the shipping charges are also exempt. Where a shipment contains both taxable and non-taxable items, the shipping charge is generally taxable.
Exemptions and resale certificates in Washington DC
Washington DC provides several sales tax exemptions. Key non-taxable categories include:
- Most groceries and food for home consumption
- Prescription drugs and medical equipment
- Sales to the federal government and its agencies
- Sales to qualifying nonprofit organizations with a valid exemption certificate
- Residential utilities (electricity, gas, and water)
Businesses that purchase goods for resale can generally claim an exemption by providing a valid resale certificate at the time of purchase. Contact the Office of Tax and Revenue for current exemption certificate forms.
Who must collect sales tax in Washington DC?
Before collecting sales tax in Washington DC, you need to determine whether your business has nexus in the District. Nexus is the legal connection that creates a sales tax obligation. If you have nexus, you must register, collect, and remit sales tax on taxable DC sales.
Economic nexus in Washington DC
You have economic nexus in Washington DC if your sales into the District exceed $100,000 in annual sales or 200 separate sales transactions in the current or previous calendar year, whichever you reach first. Only direct sales count — marketplace sales handled by the facilitator do not.

| Inventory | Maintaining a stock of goods in Washington DC for sale. |

Marketplace facilitator rules in Washington DC

Sales tax rates in Washington DC
Washington DC has a general sales tax rate of 6%. However, the District levies different rates on specific categories of purchases.
How Washington DC sales tax is structured
| Category | Tax rate |
|---|---|
| General retail sales, SaaS, digital products | 6% |
| Restaurant meals and alcohol sold on-premise | 10% |
| Hotels and lodging | ~15.95% (6% base + hotel surcharges) |
| Parking | 18% |
| Rental vehicles | 10% |
Because Washington DC is a single jurisdiction with no municipalities, the same rates apply everywhere in the District. There are no county, city, or district add-ons beyond the category-specific rates above.
How to calculate sales tax in Washington DC
For most goods and SaaS products, apply the flat 6% rate to the sale price. For restaurant meals, apply 10%; for parking, apply 18%.
Example: You sell a $200 SaaS subscription to a business in Washington DC. At the flat 6% rate, you collect $12 in sales tax, making the total $212.

Filing and payment in Washington DC
How often do you file sales tax in Washington DC?
Washington DC assigns your filing frequency at registration based on your expected sales volume — monthly, quarterly, or annually. Higher-volume sellers typically file monthly.
When are Washington DC sales tax returns due?

Penalties and compliance risks in Washington DC
Late filing or late payment in Washington DC triggers penalties and interest charges from the original due date. Common compliance pitfalls to avoid:
- Missing the economic nexus threshold — exceeding $100,000 or 200 transactions without registering creates back-tax liability.
- Assuming SaaS or digital products are exempt — Washington DC taxes both categories.
- Forgetting zero returns — failing to file even when you owe nothing results in penalties.
For penalty details, see the Office of Tax and Revenue.
