Free online tax filing sponsored by the state and nonprofits.

By filing taxes yourself, you can keep your whole tax refund.

The state, along with nonprofit agencies Stand By Me and the United Way of Delaware, sponsors a free electronic tax filing service. The “My Free Taxes  Delaware” website allows taxpayers to file their income tax from home or from a library. Visit www.myfreetaxesde.com.
