Corporate tax
Unincorporated businesses with gross receipts over $12,000 pay DC's unincorporated business franchise tax, 8.25% for tax year 2025, after a 30% salary allowance for owners and a $5,000 exemption. A business is exempt if more than 80% of its gross income comes from its members' personal services and capital is not a material income-producing factor.
What it changes in a sale
Many professional practices here are LLCs or partnerships, so this tax often applies. It's paid by the entity and reduces the cash the business throws off, which a buyer's model treats as an ongoing cost. Firms that qualify for the personal-services exemption look different on paper.
