Does New Mexico offer a 529 tax deduction?

Yes, and it is generous. New Mexico allows a full state income tax deduction for contributions to a New Mexico 529 plan (The Education Plan), with no annual dollar cap. Your benefit equals your contribution times your marginal state rate.

Is there a contribution limit for the deduction?

New Mexico is one of the few states with an unlimited annual deduction for in-state 529 contributions. You can deduct the full amount contributed to a New Mexico plan, up to your total taxable income.

How is my tax savings calculated?

Because the contribution is fully deductible, your savings equal the contribution multiplied by your marginal New Mexico tax rate. A 5,000 dollar contribution at a 4.7 percent marginal rate saves about 235 dollars in state tax.

Do out-of-state 529 plans qualify?

No. The New Mexico deduction applies only to contributions to a New Mexico-sponsored 529 plan. Contributions to another state's plan are not deductible on your New Mexico return.

Is this an exact figure?

It is an estimate. Your true benefit depends on your full return, since the deduction can push some income into a lower bracket. The tool uses your marginal rate as a close approximation.

New Mexico is one of a handful of states that lets you deduct your full 529 plan contribution with no annual cap. This calculator estimates the state income tax you save by contributing to a New Mexico 529 plan, based on your marginal tax rate.

How it works

Because the contribution is fully deductible, the savings are simply the contribution times your marginal rate:

marginal rate = bracket your taxable income falls in (1.7% to 5.9%)
tax savings    = deductible contribution × marginal rate

The deduction applies only to New Mexico-sponsored 529 plans, and there is no dollar limit, so high contributions still receive full deductibility up to your taxable income.

Example and notes

A married couple with 90,000 dollars of New Mexico taxable income sits in the 4.9 percent marginal bracket. A 6,000 dollar contribution to The Education Plan saves them about 294 dollars in state income tax this year. Remember this benefit is on top of tax-free growth and withdrawals for qualified education expenses. Always confirm current rules with the plan administrator, since only New Mexico plans qualify for the state deduction.
