This guide is for businesses that need clarity on common District of Columbia Sales and Use Tax issues, including:
- When should I collect and remit DC sales or use tax?
- What happens if I should have collected DC sales tax but didn't?
- What can I do after receiving an audit notice from the DC Office of Tax and Revenue?
- How to defend against a sales tax assessment in DC.
Who Needs to Collect District of Columbia Sales and Use Tax?
DC sales tax applies to business owners, retailers, and other sellers of tangible personal property and enumerated taxable services that have nexus with the District. DC use tax can also apply to consumers and businesses that use property in DC on which no DC sales tax was paid at the time of purchase.
How Do I Know If I Have Nexus in DC for Paying Sales Tax?
The DC Office of Tax and Revenue (OTR) generally determines a business to have nexus if it has a *physical presence* in the District, including:
- Occupying a commercial space such as an office, storefront, distribution center, or warehouse in DC.
- Sales reps, employees, or agents who conduct business activities in DC (sell, deliver, install, take orders for taxable items).
- Assembling, installing, servicing, or repairing products in DC.
- Owning or renting real property or tangible personal property in DC, including computer servers used to solicit orders.
- Holding inventory in DC, including through a third-party fulfillment service (e.g., Fulfilled by Amazon).
In addition, online businesses without a physical presence in DC can still have economic nexus based on annual sales — see the next section.
Expanded Nexus for Internet Sales in DC After Wayfair
Effective January 1, 2019, under DC Code § 47-2201(d), a remote seller or marketplace facilitator must register with OTR to collect and remit DC sales and use taxes if, in the previous or current calendar year, the seller has:
- More than $100,000 in gross receipts from DC sales, OR
- 200 or more separate retail sales delivered into DC.
Both thresholds are evaluated on a rolling basis. Marketplace sales count toward the seller's threshold (whether or not the seller collects on those sales). DC does not exclude wholesale or exempt sales from the threshold calculation.
DC Sales Made Through Marketplace Providers
Under DC law, marketplace facilitators that meet the economic nexus thresholds are required to collect and remit DC sales tax on behalf of their marketplace sellers. If you sell on Amazon, Etsy, eBay, or a similar facilitator that is registered in DC, you are generally not responsible for collecting DC sales tax on those facilitator-mediated sales — but you may still need to register and file if you have any direct DC sales of your own.
Marketplace sellers should obtain documentation from each facilitator confirming the facilitator's collection responsibility, and should still track marketplace sales for purposes of the economic nexus thresholds.
Which Sales Are Subject to DC Sales Tax?
General Transactions and DC's Multiple Sales Tax Rates
DC's general sales tax rate is 6%, but DC imposes higher special rates on specific categories of transactions — one of the more unusual features of DC sales tax:
- 6% — General tangible personal property and most enumerated services
- 10% — Restaurants, bars, prepared food, alcoholic beverages for on-premises consumption
- 10.25% — Off-premises alcoholic beverages, rental cars, and certain other categories
- 14.95% — Hotels and other transient lodging
- 18% — Commercial parking (one of the highest parking-tax rates in the country)
- $4.50 per pack — Cigarettes (in addition to other tobacco taxes)
Determining which rate applies — and tracking changes when DC adjusts a category — is one of the most common compliance failures DC OTR uncovers during an audit. See DC Code Title 47, Chapter 20 for the full rate schedule.
Services
DC taxes an enumerated list of services, including but not limited to:
- Real property maintenance services
- Landscaping services
- Carpet, drapery, and upholstery cleaning
- Information services
- Data processing services
- Telecommunications services
- Personal training and other personal services
- Real property security services
- Parking services
Professional services (legal, accounting, medical) and most other non-enumerated services are generally not taxable in DC. See DC Code § 47-2001 for the full enumerated list.
Software and Digital Goods
DC's treatment of software and digital products is broader than in many states:
- Prewritten (canned) software is taxable, whether delivered electronically, on tangible media, or through a SaaS model.
- Software as a Service (SaaS) is taxable in DC, including subscription-based access to remotely hosted applications.
- Digital goods — digital audio, video, books, and similar products — are taxable.
- Custom software developed for a specific customer is generally not taxable.
- Data processing and information services are taxable as enumerated services.
DC's broad SaaS taxation makes it one of the higher-exposure jurisdictions for software and technology businesses.
Shipping & Handling
DC's general rule: delivery and handling charges are taxable when associated with the sale of a taxable item, and non-taxable when associated with the sale of a non-taxable item — regardless of whether the delivery is performed by the seller, a common carrier, or the U.S. Postal Service, and regardless of whether the charge is separately stated. For mixed-taxable shipments, charges may be allocated based on price or weight of the taxable portion.
Drop Shipments
DC recognizes two transactions in a drop-shipment scenario: (1) the sale from the drop-shipper to the reseller, and (2) the sale from the reseller to the DC customer. If the reseller provides a valid DC or multi-state resale certificate, the first transaction is exempt and the reseller (assuming the reseller has DC nexus) is responsible for collecting DC sales tax on the second transaction.
If the reseller does not have DC nexus and the drop-shipper does, the drop-shipper may be required to collect DC sales tax on the wholesale sale unless an acceptable exemption certificate is provided.
Local Rates in DC
Unlike states with hundreds of overlapping local jurisdictions, DC is a single tax jurisdiction — there are no county, city, or special-district sales taxes layered on top of DC's rates. The applicable rate is determined entirely by the category of transaction (6% / 10% / 10.25% / 14.95% / 18%), not by the customer's location within DC.
This simplifies sourcing but does not simplify rate determination — businesses must correctly classify each transaction to the right category, which is where most DC audit assessments originate.
What Happens If You Haven't Been Collecting DC Sales Tax?
The answer depends on whether you are registered for DC sales tax and whether OTR has already contacted you about an audit or outstanding liability.
One option may be to voluntarily disclose past liability through a Voluntary Disclosure Agreement (VDA). The feasibility and value of this option depend on your specific situation.
Two options generally exist for businesses with DC nexus that have not been collecting:
- Register with OTR and pay back taxes, penalties, and interest; or
- Complete a DC VDA to limit lookback exposure and eliminate most penalties.
Option 1: Register to Pay Back Taxes, Penalties, and Interest
Sometimes registering with OTR and paying owed tax makes more sense than a VDA — for example, when past liabilities and penalties are small enough that the administrative cost of a VDA would exceed the savings.
When registration and payment may make more sense than a VDA:
- Your business has had DC nexus for less than three years.
- The penalty amount is *less* than the professional fees charged for a VDA.
- Your issues are *not* the result of uncollected sales tax (for example, missed remittance of collected tax).
Note: Registering with OTR will not eliminate past tax liability or interest.
Option 2: Voluntary Disclosure Agreement (VDA)
DC's standard lookback period for a VDA is 3 years. The DC Voluntary Disclosure Program is administered by OTR and is the right tool when a business has extended past exposure and wants to limit the period of liability and eliminate civil penalties.
The benefit of doing a DC VDA depends on:
- When you first established DC nexus.
- Whether the penalty savings exceed the professional fees for the VDA.
- Whether your issues stem from collected-but-not-remitted tax (which is generally not eligible for VDA penalty relief).
DC VDAs are typically negotiated anonymously through a representative until terms are agreed and the taxpayer's identity is disclosed.
What Happens After I Receive a DC Sales and Use Tax Audit Notice?
OTR regularly audits businesses with return discrepancies, missing returns, or remittances that appear inconsistent with the Office's data (federal returns, 1099-K reports, marketplace facilitator reports). Businesses that receive a DC audit notice should consider:
- Your experience handling DC sales and use tax audits.
- Your ability to evaluate document requests and decide what to provide.
- Your understanding of your DC sales tax exposure.
If you are unsure on any of these points, hiring a professional may be the right move. Contact us to learn how our sales tax professionals can give you the confidence needed to manage the DC audit process effectively.

DC Sales Tax Audit Process
A DC sales tax audit generally follows a predictable sequence: notice → entrance conference → records request → fieldwork → exit conference → audit report → Notice of Proposed Assessment. The auditor will typically request three years of sales records, exemption certificates, federal income tax returns, bank statements, and general ledger detail.
What the DC Sales Tax Auditor May Do After Sending the Audit Notice
- The auditor will conduct pre-audit research using third-party data (federal returns, 1099-K reports, marketplace facilitator reports).
- The auditor may schedule an entrance conference to outline scope and request initial documents.
- The auditor will request documents — many of which may not be relevant or which you may not be required to provide.
What Happens During the DC Audit
- The auditor will compare your DC sales tax returns to your federal income tax returns, bank statements, and other available records to verify all sales were reported.
- The auditor will review your exempt and out-of-DC sales, including the supporting exemption certificates.
- The auditor will conduct a use tax review of business expenses — advertising, auto and truck expense, repair and maintenance, rent, office expense, miscellaneous expense, supplies, and equipment.
*NOTE: A small classification error — for example, treating prepared food sales at 6% instead of 10% — can compound into a substantial liability over the audit period.*
Remember: if your business buys an item online without paying DC sales tax to the seller, your business still has an obligation to remit DC use tax. Failure to track this often produces surprise use-tax assessments during a DC audit.
Defending Your Business's Sales Tax Position After a DC Audit
One of the final audit steps is an exit conference, where the auditor produces an audit report and proposed assessment. It is advisable to have a sales tax professional present — this is your first opportunity to push back on areas where the auditor overstepped or misapplied DC's sales tax laws.
We generally recommend that businesses refrain from agreeing to the assessment until a sales tax professional has reviewed the audit report.
Contesting DC Audit Findings with the Auditor
After the audit, the auditor will issue a proposed assessment. Documentation issues — exemption certificates, proof tax was paid, calculation errors — are best resolved with the auditor at this stage. Legal interpretations of DC's sales tax law typically cannot be resolved at the auditor level and will require formal protest.
If a resolution cannot be reached with the auditor, the next step is to file a formal protest with OTR.
DC Notice of Proposed Assessment and Protest Rights
If you cannot resolve issues with the auditor, OTR will issue a Notice of Proposed Assessment. Under DC Code § 47-4312, a taxpayer who disagrees with a Notice of Proposed Assessment must file a written protest within 30 days of the date of the notice (or 180 days, for non-residents in certain cases).
The protest must:
- Identify the taxpayer and the assessment being contested;
- Specify the tax periods and amounts in dispute;
- Set out the facts and the legal grounds supporting the protest; and
- Be signed by the taxpayer or an authorized representative.
Missing the 30-day deadline generally makes the assessment final and very difficult to reopen.
Settling a DC Sales Tax Liability
Along the way, you may have an opportunity to settle your DC sales tax case by negotiating with OTR. Often, you can reach better results through informal settlement than at the auditor level. DC also accepts Offers in Compromise in narrow circumstances when full payment is not economically feasible.
If you or your professional team rarely does state and local tax work, it can be difficult to evaluate a fair versus unreasonable DC sales tax settlement. We don't recommend trying to negotiate a settlement without an experienced DC tax practitioner.
Contest a DC Jeopardy Assessment
Under DC Code § 47-4452, the DC Office of Tax and Revenue may issue a jeopardy assessment when the Mayor (acting through OTR) believes collection of sales and use tax will be jeopardized by delay — for example, when a taxpayer is leaving the District, dissipating assets, transferring inventory out of DC, or otherwise placing collection at risk. The tax, interest, and penalties become immediately due and payable, and OTR may begin enforced collection (liens, levies, distraint warrants) without waiting for the standard 30-day protest period to run.
A DC jeopardy assessment may be challenged, but the deadlines are compressed and OTR may require a bond or other security equal to the assessment before staying collection. Because every standard procedural protection is shortened, it is critical to engage an experienced DC sales tax professional immediately upon receipt of the jeopardy notice.
DC Administrative Hearings and Tax Court
If you cannot resolve your case within OTR or if your protest is denied, your next venue is the DC Office of Administrative Hearings (OAH) — DC's independent administrative tribunal. A petition must generally be filed with OAH within 30 days of OTR's final determination on the protest.
OAH hearings are conducted before an Administrative Law Judge and are similar in formality to a court trial: testimony, exhibits, discovery (in some cases), motion practice, and post-hearing briefing all apply. The ALJ issues a written decision.
If you disagree with the OAH decision, you may appeal to the Tax Division of the DC Superior Court, and from there to the DC Court of Appeals. Many DC sales tax disputes are filed directly in the Superior Court Tax Division — an alternative path that bypasses OAH and requires payment of the assessment (or filing a bond) before filing the petition.
Because of the formality involved and the strategic decisions about which forum to choose, representation by an experienced DC state and local tax practitioner is essential at this stage.
