Delaware extends personal income tax filing date to July 15

State continues processing returns; taxpayers urged to file
March 24, 2020

The Delaware Division of Revenue announced the deadline for taxpayers to file their 2019 Delaware personal income tax returns has been extended to Wednesday, July 15.

The division and the Internal Revenue Service remain open, and taxpayers are encouraged to continue to file their state and federal returns electronically or by mail.

"Although the filing deadline has been extended, individuals are still urged to file as soon as possible," said Jennifer Hudson, director of revenue. "Filing electronically with direct deposit remains the fastest way to get your refund. Although we are operating with modified staffing arrangements to ensure the health and safety of our staff and customers, the division of revenue continues to operate in support of the state and its taxpayers. We are continuing to process tax returns and issue refunds.”

The division’s public service windows are currently closed, but staff are available to respond to taxpayer questions by email. Inquiries may be sent to any of the email addresses listed on the website. Staff will respond by email or phone.

The filing deadline has been extended at a time when Gov. John Carney has ordered all nonessential businesses to close in order to help prevent the spread of COVID-19. Under Delaware law, the filing deadline for corporate income taxes is tied to the federal income tax due date, which was recently extended to July 15.

The director of the division of revenue has additional authority to grant reasonable extensions for other tax filings deemed to be appropriate. Under a Technical Information Memorandum 2020-01, the division has also extended income tax filing deadlines for corporate final, corporate tentative, estimated personal income taxes and fiduciary income taxes due in April to July 15. All other returns remain due without extension.

While division staff continue to process returns, some taxpayers with complex returns, filing errors, or paper submissions may experience delays. Taxpayers with questions about the status of their refund may use online tools or email

Individuals who are unable to meet the July 15 filing deadline may file an extension request on or before July 15 by email to, or through their tax preparer.
