Tax landscape for small businesses
District of Columbia small business taxes include individual income tax rates ranging from 4% to 10.75%, with the top rate applying to income over $1 million. The general sales tax rate is 6% on most goods, but D.C. applies significantly higher rates to specific categories: restaurant meals are taxed at 10%, alcohol at 10.25%, and parking at 18%.
D.C. imposes a corporate franchise tax of 8.25% on net income for businesses operating in the district. Unincorporated businesses — including sole proprietors, partnerships, and LLCs — with more than $12,000 in D.C. gross receipts must also file a franchise tax return using Form D-30.
D.C. has a unique tax environment since it functions as both a city and a state-level government, meaning there are no additional county or municipal tax layers. The Office of Tax and Revenue (OTR) handles all filings, and the single-jurisdiction structure simplifies compliance compared to most states with multiple local taxing authorities.
Small business owners benefit from several targeted programs, most notably the Qualified High Technology Company (QHTC) incentive, which offers significant tax breaks for eligible technology businesses including reduced franchise tax rates, personal property tax exemptions, and credits for hiring D.C. residents.
D.C.'s economy is heavily driven by government, professional services, technology, and hospitality sectors. The district's high median income and dense urban market create strong demand for small business services, but the high cost of living and competitive commercial real estate market require careful financial planning. Business owners should pay close attention to the different sales tax rates across product categories and the low $12,000 gross receipts filing threshold for the franchise tax.

Filing requirements
Common themes—not a complete checklist for your business.
D.C. individual income tax return (Form D-40)
File with the Office of Tax and Revenue by April 15. All D.C. residents and those with D.C.-sourced income must file. D.C. starts with federal adjusted gross income and applies district-specific modifications. Extensions through October 15 are available but any tax owed is due by the original deadline.
Sales tax registration and filing
Register for a sales tax certificate with OTR before making any taxable sales. File monthly or quarterly depending on volume. Pay close attention to the different rates for each category: 6% general, 10% restaurant meals, 10.25% alcohol, 10% transient accommodations, and 18% parking. Misapplying rates can trigger audits and penalties.
Corporate franchise tax (Form D-20)
All incorporated businesses operating in D.C. with gross receipts over $12,000 must file Form D-20 and pay the 8.25% franchise tax on net D.C. income. Unincorporated businesses — including sole proprietors and partnerships — with over $12,000 in D.C. gross receipts file Form D-30 instead. The $12,000 threshold is notably low.
Estimated tax payments
Individuals expecting to owe $100 or more and corporations expecting to owe $1,000 or more must make quarterly estimated payments. Individual payments are due in April, June, September, and January. Corporate estimates follow the same schedule. Underpayment penalties apply if installments fall below the required thresholds.
Business license registration (DCRA)
Most businesses operating in D.C. must obtain a Basic Business License (BBL) from the Department of Consumer and Regulatory Affairs. License types and fees vary by business activity. Some categories require additional endorsements, inspections, or professional certifications before the license is issued.
Employer withholding and unemployment insurance
D.C. employers must register with OTR for income tax withholding and with the Department of Employment Services for unemployment insurance. Withholding returns are filed quarterly on Form FR-900Q, and annual reconciliation Form FR-900A is due by January 31 along with copies of all W-2s.

Practical tips
- Understand the different sales tax rates — meals at 10%, alcohol at 10.25%, parking at 18% — and ensure your invoicing reflects the correct category for each transaction.
- Investigate QHTC status if you run a technology business in D.C. — the tax incentives include reduced corporate franchise tax and personal property tax exemptions.
- D.C. has no county or additional local taxes since it functions as a single jurisdiction, simplifying compliance compared to most states.
- The $12,000 gross receipts threshold is low — most businesses operating in D.C. will need to file a franchise tax return even with minimal revenue.
- Take advantage of D.C. credits for hiring residents from specific wards or target populations if you are expanding your workforce.
- Budget for D.C.'s high commercial property tax rates when leasing or purchasing office space — commercial rates are significantly higher than residential rates.
- Set aside 35%–40% of net self-employment income for combined federal and D.C. tax obligations given the district's high income tax rates.
- Consider the D.C. Small Retailer Property Tax Relief Credit if you operate a small retail business with a physical location in the district.
