PERSONAL INCOME TAX

Filing Information


  • Many state revenue agencies, including Delaware, are requesting additional information this filing season in an effort to combat stolen-identity tax fraud and to protect you and your tax return on returns filed online using the IRS E-File Tax System. If you and your spouse have a driver's license or state issued identification card, please provide the requested information from it. The return will not be rejected if you do not provide a driver's license or state-issued identification, but it will assist us to properly identify the taxpayer and ensure faster tax return processing.

    • Why is my refund taking longer to process?
      Criminals are attempting to steal tax refunds using stolen personal information. The Division of Revenue reviews every return for accuracy to ensure that your refund money stays out of the hands of criminals.

    • When can I expect my refund?
      The Division does not provide estimated timeframes for refund processing because every return is different and every year is different. You can check on the status of your refund throughout the process here.

    • Can I do anything to speed up the process?
      If you get a letter from the Division, respond with the requested information so we can complete the review and send out your refund.

BUSINESS TAX

New Business Tax Return Due Dates for Partnerships and Corporations

  • The Internal Revenue Code now requires that:
    • Partnership returns are due on or before the 15th day of the third month following the expiration of the taxable period (March 15 for calendar year taxpayers).
    • S corporation returns are due on or before the 15th day of the third month following the expiration of the taxable period (March 15 for calendar year taxpayers). This has not changed from prior years.
    • Returns for C corporations are now due on or before the 15th day of the fourth month following the expiration of the taxable period (April 15 for calendar year taxpayers).
  • Delaware has issued TIM 2017-1 granting an automatic extension of time to all C corporations to the due date of the corporation’s federal income tax return, without regard to extensions. The Delaware due dates for partnership and S corporation returns have not changed. As a result, the due dates for Delaware business returns for the 2016 tax year are as follows:
    • Partnership returns are due on or before the 30th day of the fourth month following the expiration of the taxable period (April 30 for calendar year taxpayers).
    • S corporation returns are due on or before the 30th day of the third month following expiration of the taxable period (March 30 for calendar year taxpayers).
    • Returns for C corporations are now due on or before the 15th day of the fourth month following the expiration of the taxable period.   Because of federal holidays, this will be April 18, 2017 for calendar year taxpayers.
  • Delaware will be enacting legislation in 2017 to adopt the same due dates for Delaware’s business tax returns, effective for tax years beginning after December 31, 2016
