Delaware: Revenue Sources
16 Del.C. § 2728
The Delaware Department of Finance shall provide a space on the face of the state individual income tax return for the 1998 tax year and each year thereafter whereby an individual may voluntarily designate a contribution of any amount desired to the Fund. The amount so designated by an individual on the state income tax return form shall be deducted from the tax refund to which the individual is entitled or added to the individual's payment and shall not constitute a charge against the income tax revenues due the State.
