District of Columbia rules for entrepreneurs

State income tax (2026): District of Columbia has a graduated state income tax for 2026: 4% to 10.75% (top rate starts at $1,000,000 for single filers). Rates are percentages. The same brackets apply to all filers: 4% up to $10,000, 6% to $40,000, 6.5% to $60,000, 8.5% to $250,000, 9.25% to $500,000, 9.75% to $1,000,000, and 10.75% above $1,000,000. This schedule has applied to tax years after 2021, and the 2026 D-40ES worksheet uses it.
State estimated tax: You must make estimated payments if you are required to file a DC income tax return and expect to owe $100 or more. Same dates as federal: April 15, June 15 and September 15, 2026, and January 15, 2027. Form D-40ES.
DC unincorporated business franchise tax (UBT): Unincorporated businesses, including sole proprietorships, with DC gross receipts over $12,000 owe 8.25% on net income after a 30% owner salary allowance and a $5,000 exemption. The minimum tax is $250 for receipts of $1 million or less and $1,000 above that. A business is exempt if more than 80% of its gross income comes from the owners' personal services and capital is not a material income-producing factor. OTR's rate table lists 8.25% through tax year 2025.
Workplace Fraud Act (construction): In construction, workers are presumed to be employees. To treat one as an independent contractor, the company must prove the worker is free from its direction and control, is economically independent, and does work outside the company's core business.
Paid Family Leave opt-in for self-employed workers: Sole proprietors, independent contractors and partners, including rideshare drivers, delivery workers, bloggers and consultants, may opt in to DC Paid Family Leave each November-December or within 60 days of becoming self-employed. They pay a contribution on DC gross self-employment income. To receive benefits they must have worked in DC more than 50% of the time. People who do not opt in when first eligible wait a year for benefits and must stay in for three years.

Federal rules for 2026

Entity choice changes your taxes

A single-member LLC is taxed like a sole proprietorship unless it elects S-corp status. The S-corp can lower payroll tax but adds payroll, a separate return and a reasonable-salary requirement.

Retirement as a tax lever

With no employees, a Solo 401(k) allows up to $72,000 in 2026. With employees, a SEP IRA or a 401(k) must generally cover eligible staff too.

Quarterly estimated taxes

No one withholds tax from self-employment income, so you generally pay estimates four times a year if you expect to owe $1,000 or more. For 2026 income the federal dates are April 15, June 15 and September 15, 2026, and January 15, 2027. Paying 100% of last year's tax (110% if your AGI was over $150,000) in four equal installments avoids the underpayment penalty.

Self-employment tax

On top of income tax, self-employed people pay 15.3% on 92.35% of net profit: 12.4% Social Security up to the 2026 wage base of $184,500, plus 2.9% Medicare with no cap. Half of it is deductible.

A worked example

A solo founder with $200,000 of profit in 2026
Self-employment tax as a sole proprietor	$28,234
Solo 401(k) maximum as a sole proprietor	$61,677
