How to Register for a Sales Tax ID in DC (Washington, D.C.)

To register for a sales tax ID in Washington, D.C., submit the FR-500 New Business Registration through MyTax.DC.gov, the registration portal used by the DC Office of Tax and Revenue (OTR). In the account-registration section, select Sales and Use Tax. This process applies to a new District sales tax account.

Washington, D.C., is a separate tax jurisdiction from Washington State. The instructions below concern the District of Columbia. A seller whose activity is in Washington State should instead review Washington sales tax registration for online and retail sellers.

Who may need a DC sales tax account

An individual or business making a taxable sale or providing a taxable service has a District sales-tax filing obligation when it has physical nexus in DC or meets the District’s economic-nexus standard. This can include a business operating at a District location as well as an out-of-state seller whose sales into DC cross the remote-seller threshold.

For an out-of-state retailer without a physical presence in the District, the collection and remittance requirement applies if the retailer exceeds either of these thresholds in the previous or current calendar year:

• More than $100,000 in gross receipts from retail sales delivered into DC; or
• More than 200 separate retail sales delivered into DC.

Because the tests use both a dollar amount and a transaction count, a remote retailer should review both measurements. Crossing either one is sufficient under the stated threshold. Remote sellers complete the online FR-500 as new businesses and identify themselves as remote sellers when prompted.

Before starting, confirm that the activity involves District taxable sales or taxable services and identify how the business connects with DC. The related guide to Washington, D.C. sales tax registration requirements provides additional context for evaluating the registration question.

Information and documents to prepare

Preparing the identifying details, responsible-party information, location addresses, and entity documents in advance can make the FR-500 easier to complete. All new businesses completing the form need an FEIN, ITIN, and/or SSN, along with the business’s legal form, primary business address, and information about any previous District registration.

Business and responsible-party details

Gather the following information before opening the application:

• The applicable FEIN, ITIN, and/or SSN;
• The legal form of the business;
• The primary business address;
• Details about any previous District registration; and
• The names, titles, home addresses, and SSNs or ITINs of proprietors, partners, or principal officers.

Every individual entered as an officer must provide an SSN or ITIN. Review the responsible-party list carefully so that the application includes the required identifying information for each person entered in that role.

Sales locations and entity records

Applicants selecting a Sales and Use Tax account must provide the addresses of all locations where they will collect District sales tax. In the online Sales and Use Tax portion of the FR-500, the applicant must add or edit those locations before proceeding. Prepare a complete location list rather than entering only the primary business address if collection will occur at additional locations.

The required attachment depends on the business or registration type:

• A corporation must attach its Articles of Incorporation.
• An LLC must attach its Articles of Organization.
• An applicant registering with a trade name must attach the Certificate of Trade Name Registration.

These records serve different purposes. The entity’s formation document corresponds to its legal structure, while the trade-name certificate applies when the registration uses a trade name. A business may therefore need to prepare the document associated with its entity type as well as the trade-name document when applicable.

How to register through MyTax.DC.gov

1. Confirm that this is a new registration. The FR-500 process is used for new registrations. If the business already has an account and needs to update it, log in to MyTax.DC.gov rather than starting a new-business registration.
2. Collect the required information. Have the business identifiers, legal form, primary address, previous District registration information, responsible-party details, and relevant entity documents ready.
3. Start the FR-500. Use MyTax.DC.gov to begin the FR-500 New Business Registration administered by the DC Office of Tax and Revenue.
4. Select the appropriate account. Choose Sales and Use Tax in the account-registration section. Selecting the correct account type is what identifies the filing as a request for a new sales and use tax account.
5. Enter the business and individual details. Supply the requested identifiers and addresses. Include the required information for proprietors, partners, or principal officers, and make sure every listed officer has an SSN or ITIN entered.
6. Add all DC sales-tax collection locations. In the Sales and Use Tax section, add or edit the addresses of every location where the business will collect District sales tax. The online application requires this location step before the applicant can proceed.
7. Answer seller-status questions accurately. An out-of-state remote seller registering online should indicate that it is a remote seller when the application prompts it to do so.
8. Attach the applicable records. Upload the Articles of Incorporation for a corporation, Articles of Organization for an LLC, or Certificate of Trade Name Registration when registering with a trade name, as applicable.
9. Review before submitting. Compare the entries with the business’s legal and formation records. In particular, check the legal form, addresses, officer information, sales locations, account selection, and attachments.

Keep a copy of the submitted information and supporting records with the business’s tax files. This gives the business a consistent reference when maintaining its account and handling later sales-tax reporting.

Special rules for remote and marketplace sellers

A remote seller should not assume that having no District storefront ends the analysis. An out-of-state retailer without a physical presence in DC must collect and remit District sales tax when it exceeds $100,000 in qualifying gross receipts or makes more than 200 qualifying separate retail sales delivered into DC during the previous or current calendar year.

A business can also act in more than one selling capacity. A seller operating as both a remote seller and a marketplace facilitator must register for two sales and use tax accounts. It must report the two sales streams separately. The registration should therefore reflect the roles the business actually performs rather than combining both streams under one account.

This dual-role rule is specifically about a seller acting as both a remote seller and a marketplace facilitator. It does not mean that every seller using a marketplace automatically needs two accounts. The relevant question is whether the seller itself operates in both stated capacities.

What to do after filing

Registration is the beginning of sales-tax account administration, not a substitute for ongoing reporting. An individual or business with taxable DC sales or taxable DC services must file when it has physical nexus in the District or meets the economic-nexus standard. Organize sales records so District activity can be identified consistently.

Businesses with multiple collection locations should maintain records that match the locations entered in the application. If the business acts as both a remote seller and marketplace facilitator, its accounting process should keep those two sales streams separate because they must be reported through separate sales and use tax accounts.

If information for an existing account changes, use the account access available through MyTax.DC.gov rather than submitting the FR-500 as though the business were registering for the first time. Retain the submitted registration details, formation documents, trade-name records, and responsible-party information so future account maintenance can be checked against the original filing.

Practical registration examples

A DC retail LLC

Consider an LLC opening a retail location in the District and making taxable sales there. For its new registration, it would use MyTax.DC.gov, complete the FR-500, and select Sales and Use Tax. It would enter the collection location, provide the required business and responsible-party information, and attach its Articles of Organization. If it registers under a trade name, it would also prepare the Certificate of Trade Name Registration.

An out-of-state online retailer

Suppose an online retailer has no physical presence in DC but records $105,000 in gross receipts from retail sales delivered into the District during the current calendar year. That amount exceeds the $100,000 remote-seller threshold. The retailer must collect and remit District sales tax, register online through the FR-500, select Sales and Use Tax, and identify itself as a remote seller when prompted.

Alternatively, suppose a remote retailer has $70,000 in gross receipts from DC-delivered retail sales but makes 205 separate retail sales delivered into DC during the relevant period. Although its receipts do not exceed $100,000, its transaction count exceeds 200. The separate-sales threshold therefore applies.

A business with two selling roles

Consider a company that sells its own products into DC as a remote seller and also operates as a marketplace facilitator. Because it acts in both specified capacities, it must register for two sales and use tax accounts and report the sales streams separately. Its records should distinguish its remote-seller activity from its marketplace-facilitator activity rather than merging both categories.
