A. Any individual whose state income tax liability in any year is lower than the amount of money held by the taxation and revenue department to the credit of such individual for that tax year may designate any portion of the income tax refund due him to be paid into the substance abuse education fund. In the case of a joint return, both individuals must make such designation.

B. The secretary of the department shall revise the state income tax form to allow the designation by individual taxpayers of such contributions in substantially the following form:

“New Mexico Substance Abuse Education Fund – Check [ ] if you wish to contribute a part or all of your tax refund to the Substance Abuse Education Fund. Enter here $                         the amount of your contribution.”.

C. The provisions of this section do not apply to refund amounts intercepted under the tax refund intercept program and any designation under the provisions of this section with respect to such intercepted refunds is void.
