The Washington DC side of each payment
Washington DC taxes the same 1099 profit on 6 graduated brackets topping out at 10.75%, so a second payment goes to the state each quarter, about $590 on the $50,000 example, against $2,620 of Washington DC income tax for the year.
The 2026 dataset carries the federal 1040-ES dates but not state-specific due dates, so confirm Washington DC's schedule and voucher with its tax agency, several states do not match the federal calendar exactly.
