Wilmington
Wilmington adds a city wage tax on residents and on nonresidents who work in the city, with returns of its own.
- The city’s earned income tax is 1.25% of wages, withheld from city residents wherever they work and from nonresidents for the work they do in Wilmington. A net profits tax at the same rate applies to businesses there.
- A nonresident based in the city has the tax apportioned by days worked there, and a day worked remotely for the employee’s own convenience counts as a day worked in Wilmington.
- An employer withholding more than $50 in the first or second month of a quarter pays it by the 15th of the next month, and quarterly returns are due April 15, July 15, October 15, and January 15.
