How to pay New Mexico estimated taxes.

New Mexico collects its own estimated tax through the New Mexico Taxation and Revenue Department, separate from the IRS. Here’s who needs to pay, when, and how to pay online.

Do you need to pay?

You owe an underpayment penalty only if your tax for the year, minus amounts withheld, is $1,000 or more. If the gap between your tax and your withholding plus estimated payments is more than $1,000, the Department checks whether you made the required annual payment.

Pay at least the lesser of 90% of your 2026 tax or 100% of your 2025 tax (the prior-year option only applies if you filed a full 12-month New Mexico return). No high-income adjustment is listed. There is no penalty if you are a first-year resident, or a full-year resident who owed zero tax on a 12-month prior-year return.

If you underpay: Interest computed daily at the quarterly IRS individual underpayment rate; the Department posts each quarter's rate on its penalty and interest rates page.

Paying New Mexico, step by step

What you need

Nothing to set up. Taxpayer Access Point (TAP) takes payments without an account.
Your Social Security number and a copy of last year's New Mexico return.
Your bank routing and account numbers.

Start at Taxpayer Access Point (TAP), New Mexico's official payment site.

Go to Taxpayer Access Point (TAP). You do not need an account.
In the Payments tile, select Make a Payment.
Enter your identifying information so the Department can locate your account.
Choose the filing period (tax year 2026) and select Estimated Payment as the payment type.
Pay by electronic check (no charge) or credit card (convenience fee applies), then submit and keep your confirmation.

Other ways to pay: Check or money order mailed with the PIT-ES voucher to New Mexico Taxation and Revenue Department, PO Box 8390, Santa Fe, NM 87504-8390. Pay in whole dollars only. The vouchers are not year specific. Credit card payments carry a convenience fee (percentage not published in the instructions).

New Mexico will not fill these payments in for you. Your preparer has to enter each estimated payment on your New Mexico return. Keep your own record of the date, amount, and confirmation number.

Extension payments

New Mexico accepts the federal automatic extension (Form 4868), giving you until October 15 for most filers, with no state form needed. If you need more time for New Mexico only, file Form RPD-41096 by the due date. The extension waives the failure-to-file and failure-to-pay penalty through the extended date if you file and pay by then, but interest still accrues from April 15. Make an extension payment with Form PIT-EXT or online through TAP (Make a Payment, then Individual).

Make this year's first estimated payment as a separate transaction, marked as an estimate for the current year.

Good to know

There is no underpayment penalty in your first year as a New Mexico resident.
If income arrives unevenly or you farm or ranch, you can reduce the penalty with Form RPD-41272 using the annualized or farmer exceptions.
Underpayment interest uses the IRS individual rate, which changes every quarter.
