Understanding how DC treats various income types — wages, Schedule C net income, capital gains, retirement distributions, and out-of-state earnings — is central to getting the return right the first time. District of Columbia's Washington-based tax administration has its own deadlines, conformity rules relative to federal law, and credit provisions that diverge from the federal 1040 in ways that regularly surprise filers. We prepare the federal return and every applicable DC schedule together, apply the correct filing status under District of Columbia law, and handle part-year and nonresident returns for anyone who moved into or out of District of Columbia during the tax year. Amended DC returns, prior-year catch-up filings, and state notice response are included for returns we prepared.
