What is a local income tax?

A local income tax is a special tax on earned income collected by local governments like counties, cities, and school districts. Fourteen states including Delaware allow local governments to collect an income tax.

While the federal income tax and the Delaware income tax are progressive income taxes with multiple tax brackets, all local income taxes are flat-rate taxes which are the same for every taxpayer regardless of income.

Another major difference between local income taxes and federal or state taxes is that most local taxes are collected only on earned income, and not on capital gains or other non-earned income like interest and dividends.

How do you pay the Wilmington income tax?

The Wilmington income tax is due on April 15th, when you file your federal and state tax returns. Because calculating your local income tax is relatively simple compared to your other tax returns, many tax preparers will file your Wilmington income tax return for free.

If you file your own taxes, the Wilmington tax collector will likely mail you a copy of the tax forms you need by April.
