If you are due a refund on your New Mexico Personal Income Tax, you have the opportunity to donate all or part to a special fund using the PIT- D, Schedule for New Mexico Voluntary Contributions. You can choose from more than a dozen worthwhile funds, which are listed on the schedule and described in the PIT-D instructions. The Taxation and Revenue Department deducts your contribution from your refund and then transfers it to the fund or funds you have chosen. On a joint return, both individuals must agree to all contributions. Changes are not allowed, so taxpayers should carefully consider their contributions.
