Washington, DC, establishes business registration requirements and tax nexus through comprehensive economic and physical presence frameworks that differ notably from those of many states.
The District maintains relatively low economic nexus thresholds of $100,000 in sales or 200 transactions, making it easier for remote sellers to trigger registration obligations compared to jurisdictions with higher thresholds.
What sets DC apart is its broad taxation of services beyond tangible goods, its retention of the 200-transaction threshold that many states have eliminated, and its comprehensive business licensing system.
Businesses must collect and remit DC's 6.5% sales tax when they establish either economic or physical nexus in the District.
DC's economic nexus standard applies to remote sellers who exceed either threshold in the current or preceding calendar year:
Both taxable and exempt sales count toward the revenue threshold, and marketplace facilitator sales where the facilitator collects tax are also included in individual seller calculations.
The 200-transaction threshold makes DC particularly aggressive toward high-volume, low-dollar sellers compared to states that have eliminated transaction counts.
Once either threshold is exceeded, businesses in Washington, D.C. must register and begin collecting sales tax immediately, without a grace period. This timing requirement provides a grace period but requires careful monitoring of sales volumes.
Traditional physical presence creates immediate nexus regardless of sales volume:
DC registration occurs through the Office of Tax and Revenue's portal using Form FR-500. Required information includes your Federal EIN, legal business name, all DC locations where sales tax is collected, and names and Social Security numbers of principal officers.
Filing frequency in Washington, DC, depends on tax volume and can be monthly, quarterly, or annually, as assigned by the Office of Tax and Revenue. Returns are due by the 20th day following the end of each filing period, even if no tax was collected during that period.
DC's franchise tax creates broader nexus obligations than many states by imposing filing requirements on businesses with DC-sourced income exceeding $12,000.
Unlike states with minimum revenue thresholds, DC requires franchise tax filings for any income derived from DC sources. This includes:
Physical presence factors (employees, property, business activities) also establish franchise tax nexus, as does exceeding the economic sales thresholds that trigger sales tax obligations.
There is no minimum dollar threshold; even $1 of DC-sourced revenue creates a filing obligation.
Businesses with a DC nexus must file annual franchise tax returns regardless of their filing obligations in other states. DC uses a single-factor apportionment formula based on gross receipts, with income allocated based on the percentage of total gross revenue derived from DC sources.
Registration occurs through the same portal used for sales tax, and returns are due by the 15th day of the fourth month after year-end for calendar-year filers. Estimated payments may be required for businesses with substantial DC tax liability.
Employment tax nexus in DC is established immediately when any employee performs work within the District, regardless of the employee's official residence or your company's location.
The following create immediate employment tax obligations:
The location where work is actually performed determines nexus, not where the employee officially resides or where your company is headquartered.
Employment nexus requires multiple registrations:
Registration must occur before any DC-based employee receives their first paycheck.
DC's approach to modern business activities creates broader nexus exposure than many traditional frameworks, particularly for service-based businesses and companies with remote workforces.
DC taxes an extensive range of services beyond tangible goods, including data processing, information services, health clubs, landscaping, security services, and car wash services. This broader tax base means service providers delivering digital solutions may trigger nexus obligations more easily than in goods-focused tax regimes.
Digital products and SaaS subscriptions count toward both the $100,000 revenue and 200-transaction thresholds.
Marketplace facilitators registered in DC must collect tax on behalf of sellers, and these facilitated sales don't count toward individual sellers' economic nexus calculations. However, if you operate across multiple marketplaces or maintain direct sales channels, you must monitor your combined exposure across all non-facilitated sales channels.
Drop-shipping relationships and affiliate marketing arrangements with DC-based partners can create physical presence nexus requiring immediate registration regardless of sales volume.
Reaching tax or employment nexus in DC often indicates sufficient business activity to require foreign entity registration with the Department of Consumer and Regulatory Affairs.
Though tax registration and foreign qualification are separate processes, crossing economic nexus thresholds typically demonstrates the level of business activity that may trigger corporate registration obligations under DC's "doing business" standards.
DC's registration requirements follow specific sequences:
DC expects comprehensive documentation supporting nexus determinations:
Records should be retained for at least three years, but tax-related payroll documents and some other records must be kept for at least four years to support potential audits or compliance reviews.
Managing DC's complex nexus landscape alongside multi-state operations creates the kind of administrative burden that drives an existential dread of not knowing compliance status.
