District of Columbia S-Corp Tax Calculator

Self-employment tax is federal — 15.3% (12.4% Social Security up to the $184,500 wage base + 2.9% Medicare) on 92.35% of your net self-employment income, the same in District of Columbia as everywhere. District of Columbia then taxes that same income at its state income-tax rate (up to 10.75%). The calculator above shows your SE tax at any income.

In District of Columbia, if your business is exempt from DC's unincorporated business tax (more than 80% of its income from your own services, with capital not a material factor), at this calculator's default assumptions, it starts paying off at $64,054 of net profit. That assumes a salary of 60% of net profit (capped at the $184,500 Social Security wage base), $2,500 a year for payroll and the extra business return, a single filer with no other income taking the $16,100 standard deduction, a business that is not a specified service business (not consulting, law, health, financial services and the like) and an LLC you already have, so its annual fee is paid either way. It counts federal payroll tax, federal income tax (including the QBI deduction the salary changes), what DC charges for the election and DC income tax on your own return, which the election changes directly. No other state income tax is in it. If your business already pays DC's unincorporated business tax, it pays off between $53,298 and $89,650 of net profit, and again between $91,287 and $160,221, and again from $307,065 — from $307,065, the QBI wage limit takes the deduction from a sole proprietor with no payroll, and the salary keeps it. A lower defensible salary moves the answer, and so do your own payroll and return quotes.

District of Columbia taxes an S-corp as a corporation, at 8.25% of net income with a $250 minimum, and leaves that income off your own DC return. If your business is exempt from DC's unincorporated business tax (more than 80% of its income from your own services, with capital not a material factor), the corporate tax is new, but it replaces DC income tax on the same dollars — this calculator counts both. If your business already pays DC's unincorporated business tax (8.25% after a $5,000 exemption and an owner allowance of up to 30% of net income), electing swaps it for the corporate tax, where your whole salary is deductible.

District of Columbia does not currently offer a pass-through entity tax (PTET) election, so the federal SALT cap ($40,400 for 2026, phasing down toward $10,000 above ~$505,000 of MAGI) applies to state taxes paid personally.

The IRS requires S-corp owner-employees to pay themselves a reasonable salary (subject to FICA) before taking distributions. This calculator assumes a salary of 60% of net profit (capped at the $184,500 Social Security wage base), with the rest taken as distributions, as an illustration — your actual reasonable compensation depends on your role and industry and should be set with a CPA.
