File Delaware Tax Returns
At less than $4 billion, Delaware's recent annual tax revenue is lower than most other states. The state also has lower income tax rates than most states. Delaware income tax rates range between 2.2% and 3.9%. Nonresidents with in-state earnings, part-time residents and permanent residents are all required to file an income tax return of some sort. Spouses of deceased taxpayers may file on their behalf.

In Delaware, the filling deadline is not the same as the federal deadline. Income tax returns must be postmarked by April 30. This also applies to tax extensions. If a taxpayer files for an extension, they must mail their income tax forms by October 30. To file an extension, you may visit the Division of Revenue's website ?or mail a form 1027I. Extensions may be filled anytime between March 1 and April 30.
Taxpayers who discover errors in prior tax filings can file an amended return with the appropriate form. Nonresidents should use a 200-02-X, and residents of must use a 200-01-X.
