Delaware Return Mailing Addresses
To file your Delaware individual income tax return, you must mail your completed form along with all required attachments to the appropriate address. The mailing address for Delaware state tax returns is:
- Delaware Division of Revenue
- PO Box 2340
- Wilmington, DE 19899-2340
Ensure you include all necessary documents as specified in the Delaware return instructions. These typically include:
- Completed DE Schedules I, II, III, IV, and V (if applicable)
- Copy of your federal Form 1040, including Pages 1 and 2, and any supporting schedules (e.g., Schedule C, D, E, F)
- W-2 forms and 1099-R forms to claim credit for Delaware tax withheld
For residents, use Form PIT-RES. For non-residents or part-year residents, use Form PIT-NON. If you are filing Form PIT-CRS (for credits such as Land and Historic Resource Conservation Credits), ensure it is properly completed and attached.
Always sign and date your return. If prepared by a paid tax preparer, they must also sign the return.
