In response to the national emergency, and following IRS Guidance: In order to protect our employees, Delaware taxpayers, our partners and the community, we have temporarily closed all Public Service offices and discontinued face-to-face service throughout the state until further notice.
All taxpayers are asked to utilize the Division of Revenue’s online services at Revenue.Delaware.gov to ensure that they remain compliant with all tax filing and payment obligations. If you are unable to find a solution through Revenue’s online services, please call our public service group at 302-577-8200, and we will provide you guidance.
All returns and payments filed with the Division of Revenue will be processed as they are received. Online filing for most returns is available at https://revenue.delaware.gov/file/. All returns received through electronic and internet filing methods are processed directly into Revenue’s system, thus allowing more expedient processing. Paper returns are processed as they are received and will be scanned into Revenue’s system for processing, but please be aware that paper returns will take longer to be processed.
