A business establishes nexus in Washington, D.C. the moment it either sets foot in the District in some tangible way or earns enough from D.C. customers to cross an economic threshold. Under D.C. nexus rules, a single remote employee working from a D.C. apartment, inventory sitting in a local warehouse, or more than $100,000 in sales delivered into the District can all pull an out-of-state business into the Corporate Franchise Tax, the Sales and Use Tax, or both. Ignoring the obligation can push penalties to 25% of the unpaid tax plus daily compounding interest, so the practical question is knowing which activities cross the line.
When You Owe the D.C. Franchise Tax
The Franchise Tax applies to corporations and to unincorporated businesses (partnerships, sole proprietors, most LLCs), each filing on its own form. The rate is 8.25% of D.C. taxable income for both.1D.C. Law Library. District of Columbia Code 47-1807.02 – Tax on Corporations – Levy and Rates
Physical presence is the traditional trigger. Owning or leasing property, running an office, keeping employees in the District, or performing services at customer sites all create an immediate franchise tax obligation. The D.C. Code defines “trade or business” broadly to include any commercial activity in the District, the leasing of property, and even activities in D.C. that benefit a related entity of the taxpayer.2D.C. Law Library. District of Columbia Code 47-1801.04 – General Definitions That last piece catches parent companies off guard: if a parent sends staff to D.C. to support a subsidiary, that activity alone can establish franchise tax nexus for the parent.
A business with no physical footprint can still owe the Franchise Tax if it earns income from D.C. sources. Unincorporated businesses hit the filing obligation once D.C.-sourced gross income exceeds $12,000 in a tax year; below that, they can file a simple affidavit (Form D-30N) instead of a full return and owe no tax.3District of Columbia Office of Tax and Revenue. D-30 Unincorporated Business Franchise Tax Forms and Instructions Corporations deriving income from D.C. sources must also file, regardless of whether they have a physical presence.
Even a loss year does not eliminate the tax. Corporations owe a minimum of $250 when D.C. gross receipts are $1 million or less, and $1,000 when they exceed $1 million.1D.C. Law Library. District of Columbia Code 47-1807.02 – Tax on Corporations – Levy and Rates The Office of Tax and Revenue (OTR) takes an expansive view of what counts as D.C.-sourced income, especially for service and intangible product sellers.
When You Owe D.C. Sales and Use Tax
Sales tax nexus runs on a separate track. A business must collect and remit D.C.’s 6% sales tax if it either has a physical presence in the District or meets an economic nexus threshold.4Office of the Chief Financial Officer. Tax Rates and Revenues, Sales and Use Taxes, Alcoholic Beverage Taxes and Tobacco Taxes
A remote seller crosses the economic line when it exceeds either threshold in the current or preceding calendar year:
- More than $100,000 in gross receipts from retail sales delivered into D.C., or
- More than 200 separate retail sales delivered into D.C.
Both taxable and exempt sales count.5D.C. Law Library. District of Columbia Code 47-2001 – Definitions The 200-transaction test catches high-volume, low-dollar sellers fast: a business averaging $20 per order hits the threshold at just $4,000 in total D.C. sales.
Once either threshold is crossed, register with OTR and start collecting tax on the very next sale. No tax is owed on transactions before the threshold was met, but collection must begin right away once it is.6DC Office of Tax and Revenue. Sales and Use Tax FAQs The tax reaches tangible personal property, certain services, and digital products.
Selling Through a Marketplace
D.C. law shifts the sales tax collection burden onto marketplace facilitators once the platform meets the economic nexus threshold. Major e-commerce sites, app stores, and similar platforms collect and remit D.C. sales tax on every sale they facilitate, even if the underlying seller would not independently have nexus.7D.C. Law Library. District of Columbia Code 47-2002.01a – Marketplace Facilitators Sales Tax Requirements
Selling through a marketplace does not fully insulate you, though. Sales made outside the platform (your own website, phone orders, pop-up events) still count toward your own $100,000 or 200-transaction threshold. Storing inventory in a D.C. fulfillment center also creates physical presence nexus on your direct sales regardless of volume.
Physical Activities That Create Nexus
Physical presence nexus applies across both the Franchise Tax and the Sales Tax, and the bar is low. Nearly any sustained, tangible connection to D.C. is enough. Common triggers include:
- A single remote employee performing any job function from a D.C. home, even part-time or purely administrative. This is the trigger that surprises the most businesses.
- Goods held in any D.C. location, including third-party fulfillment centers and warehouses.
- Technicians, consultants, or installers visiting D.C. customer sites on a regular basis. One-off visits may not qualify; a pattern of service calls almost certainly will.
- Any office footprint, including a desk at a co-working space.
- Employees or agents regularly visiting D.C. clients to maintain relationships or service accounts (this goes beyond mere solicitation).
Attending a trade show solely to take orders that are approved out of state generally does not create nexus, provided representatives don’t close sales on the spot, handle inventory, or perform services while in town.
The Narrow Federal Shield: P.L. 86-272
Public Law 86-272 prevents a state or the District from imposing a net income tax on a company whose only in-jurisdiction activity is soliciting orders for tangible personal property, when those orders are approved and shipped from outside.8Multistate Tax Commission. Statement of Information Concerning Practices of Multistate Tax Commission and Signatory States Under Public Law 86-272 If your salespeople pitch a physical product to D.C. clients and every order is approved at headquarters, P.L. 86-272 keeps you outside the Franchise Tax.
The shield falls apart quickly in practice. Selling services, licensing software, or providing digital products falls outside P.L. 86-272 because those are not tangible personal property. A business that does sell physical goods loses the protection the moment it crosses from soliciting into delivering, installing, or providing technical support in D.C. The Multistate Tax Commission has also stated that certain internet-based activities, such as placing cookies on D.C. residents’ devices or allowing them to interact with a company app, can exceed the scope of protected solicitation, and D.C. follows this interpretation closely.
One boundary catches many owners: P.L. 86-272 blocks only net income taxes. It does not shield partnerships and most LLCs from the Unincorporated Business Franchise Tax, because D.C. characterizes that tax differently. A partnership whose only D.C. activity is soliciting sales of physical goods may still owe the unincorporated franchise tax.9District of Columbia Office of Tax and Revenue.

The Employee Withholding Piece
Once a business has someone working in D.C., whether at an office or from home, the employer also has to withhold D.C. income tax from that employee’s wages. That means registering for withholding tax, filing withholding returns, and remitting the amounts to OTR. The obligation applies even if the employer is based in another state and the D.C. employee is the company’s only connection to the District. Withholding registration happens automatically as part of the FR-500 business registration.
What Happens If You Ignore the Obligation
D.C. stacks three layers of cost on non-compliance:
A late filing penalty of 5% of the unpaid tax for each month or partial month the return is overdue, capped at 25%.10D.C. Law Library. District of Columbia Code 47-4213 – Failure to File Return or to Pay Tax
A late payment penalty of another 5% per month on the unpaid balance, also capped at 25%. This runs on top of the filing penalty, so a business that both fails to file and fails to pay racks up penalties at 10% per month.10D.C. Law Library. District of Columbia Code 47-4213 – Failure to File Return or to Pay Tax
Interest at 10% per year, compounded daily, from the original due date.11D.C. Law Library. District of Columbia Code Title 47 Chapter 42 – Interest and Penalties
Negligence or a substantial understatement of income adds a separate accuracy-related penalty of 20% of the underpayment. Fraud takes the penalty to 75%.
Coming Forward Voluntarily
A business that realizes it should have been filing but never registered can approach OTR through a Voluntary Disclosure Agreement (VDA). The main benefit is a shorter look-back: OTR will typically require back-filing for three years or the date nexus was first established, whichever is shorter.12District of Columbia Office of Tax and Revenue. Voluntary Disclosure Program
In egregious situations OTR can extend the look-back to five years. One scenario gets no leniency at all: if a business collected sales tax from D.C. customers but never remitted it, the look-back stretches to the longer of five years or the entire period nexus existed.12District of Columbia Office of Tax and Revenue. Voluntary Disclosure Program A VDA must be initiated before OTR contacts the business about the liability. Once the District reaches out first, the option disappears.
Registering and Filing After Nexus Exists
Registration runs through the Combined Business Tax Registration Application (Form FR-500), filed online at MyTax.DC.gov. The FR-500 covers Franchise Tax, Sales and Use Tax, and Withholding Tax in a single application.13MyTax.DC.gov. How to Register a New Business Form FR-500
Many businesses also need a D.C. Basic Business License from the Department of Licensing and Consumer Protection. Tax registration through OTR must be completed first. OTR additionally requires a Certificate of Clean Hands, which is proof the business owes no outstanding D.C. taxes, fees, or fines above $100, before it can obtain or renew licenses, permits, or government contracts.14Government of the District of Columbia. Certificate of Clean Hands Brochure
Corporations file Form D-20 annually; unincorporated businesses file Form D-30. Calendar-year filers are due by April 15, and fiscal-year filers by the 15th day of the fourth month after year-end. When expected annual franchise tax liability exceeds $1,000, quarterly estimated payments are required.15Office of Tax and Revenue. Corporate Business Franchise Tax Forms
Sales tax returns use the FR-800 series and must be filed electronically through MyTax.DC.gov. OTR assigns filing frequency based on tax liability per period, and remote sellers newly registering because of economic nexus are typically placed on a monthly schedule.16District of Columbia Office of the Chief Financial Officer.
