Delaware - DE - Taxpayer

Delaware Taxpayer Portal is the online service operated by the Delaware Division of Revenue at tax.delaware.gov, allowing individuals and businesses to manage state tax obligations electronically. It serves Delaware residents, part-year residents, nonresidents with state tax liability, and registered businesses that must file corporate, withholding, gross receipts, or other state taxes. Through the portal, users can file personal income tax returns, submit estimated payments, and check the status of refunds. Business users can register accounts, file and pay various business tax types, and manage licenses required for operating within the state. The platform centralizes filing, payment, and account management functions to help taxpayers meet Delaware's state tax compliance requirements without in-person visits to a revenue office.
