For a single filer in District of Columbia with $72,000 of 1099 income and $9,000 of expenses and no other income, the calculator estimates a set-aside rate of 21.0%: $8,902 of self-employment tax, $3,827 of federal income tax, and $2,359 of District of Columbia income tax.
Federal estimated payments are due April 15, June 15 and September 15, 2026, and January 15, 2027, if you expect to owe $1,000 or more after withholding. District of Columbia has its own estimated tax schedule and safe-harbor rules; the state share in the tracker is a quarter of the projected annual state tax.
