How to file tax extensions in Delaware

The state of Delaware will grant you an automatic 5½-month tax extension if you filed a Federal tax extension (with the IRS) and you have no state income tax due.

However, If you owe any state tax, it must still be paid by the original filing deadline to avoid penalties and interest charges.

To request a state tax extension (for Forms 200-01 or 200-02), use Delaware Tax Form 1027 (Application for Automatic Extension of Time to File a Delaware Individual Income Tax Return).

You may also request an extension online from the Delaware Division of Revenue. Your state tax extension application must be received by the original filing due date (usually April 30).

If you are including payment with your tax extension request, mail Form 1027 to:
Delaware Division of Revenue, PO Box 508, Wilmington, DE 19899-0508

If you are not including a payment with your tax extension request, mail Form 1027 to:
Delaware Division of Revenue, PO Box 8765, Wilmington, DE 19899-8765
