What's different about District of Columbia for the self-employed

DC's 2026 standard deduction is in flux: a July 2026 budget law keeps the 2025 amounts ($15,000 single / $30,000 joint), which this estimate uses, but DC has not published final 2026 instructions. If the federal amounts apply instead, DC tax is roughly $100–$240 lower.
DC's 8.25% unincorporated business franchise tax applies to sole proprietors with more than $12,000 of DC gross income, after a 30% owner salary allowance and a $5,000 exemption. Businesses where more than 80% of income comes from the owner's personal services (and capital is not material) are exempt — which covers many solo freelancers and consultants.
DC charges an unincorporated business franchise tax (Form D-30) on unincorporated businesses, including sole proprietors and LLCs, with more than $12,000 of DC-source gross income. The rate is 8.25%, with a $250 minimum tax even with a loss ($1,000 if DC gross receipts exceed $1 million).
A late biennial report adds a $100 late fee for for-profit entities.
The general sales tax rate stays at 6% through September 30, 2027; the scheduled increase to 7% was postponed.
