New Mexico State Tax Forms

New Mexico tax forms are generally organized by taxpayer type, with the two primary categories being individual taxpayers and business or entity taxpayers.

Each category has its own core return and supporting schedules. The most common primary forms are Form PIT-1 for personal income tax and Form CIT-1 for corporate income tax.

Taxpayers should always use the most current versions of New Mexico tax forms and instructions, which are available on the official New Mexico Taxation and Revenue Department (TRD) website.

The state strongly encourages taxpayers to file electronically using the Taxpayer Access Point (TAP) portal, which offers faster processing, built-in error checks, and quicker refunds compared to paper filing.

Personal Income Tax (PIT) Forms

Most New Mexico residents who are required to file a federal income tax return must also file a New Mexico personal income tax return using Form PIT-1. Depending on income sources and credits claimed, additional schedules may be required.

Common Personal Income Tax Forms

• Form PIT-1 – New Mexico Personal Income Tax Return
  The primary return for New Mexico residents, part-year residents, and certain nonresidents. It reports income, deductions, exemptions, tax owed, and payments.
• Form PIT-ADJ – Additions, Deductions, and Exemptions Schedule
  Used to adjust federal adjusted gross income (AGI) for New Mexico-specific additions and deductions, such as interest from other states’ bonds or certain retirement exclusions.
• Form PIT-B – Allocation and Apportionment of Income
  Required for residents with income earned outside New Mexico and for nonresidents with income from New Mexico sources.
• Form PIT-RC – Rebate and Credit Schedule
  Used to claim refundable and nonrefundable credits and rebates, including low-income tax rebates and other state-authorized credits.
• Form PIT-CR – Business-Related Income Tax Credit Schedule
  Allows individual taxpayers to claim business-related credits passed through from partnerships, S corporations, or other qualifying entities.
• Form PIT-ES – Estimated Tax Payment Voucher
  Used by individuals who must make quarterly estimated tax payments because insufficient tax is withheld from wages or other income.
• Form RPD-41083 – Affidavit to Obtain Refund for a Deceased Taxpayer
  Required when requesting a refund on behalf of a deceased taxpayer who did not have a surviving spouse filing a joint return.

Business and Entity Tax Forms

Businesses operating in New Mexico must file specific tax forms based on their legal structure and the tax programs they are subject to, such as Corporate Income Tax, Gross Receipts Tax (GRT), or Pass-Through Entity reporting.

Common Business and Entity Forms

• Form CIT-1 – Corporate Income and Franchise Tax Return
  Filed annually by C corporations conducting business in New Mexico.
• Form S-Corp – Subchapter S Corporate Income and Franchise Tax Return
  Used by S corporations to report income, deductions, and tax obligations at the state level.
• Form PTE – Pass-Through Entity Information Return
  Filed by partnerships, S corporations, and other pass-through entities to report income allocated to owners or members.
• Form FID-1 – Fiduciary Income Tax Return
  Required for estates and trusts with New Mexico taxable income.
• Form CRS-1 – Combined Reporting System Return
  Used by businesses to report and pay Gross Receipts Tax (GRT), withholding tax, and certain excise taxes. Both short and long versions are available depending on business complexity.
• Form ACD-31015 – Business Tax Registration Application and Update
  Used to register a business with the state, update account information, and obtain or modify a New Mexico Business Tax Identification Number (NMBTIN).

New Mexico Withholding (W-4) Information

New Mexico does not issue a separate state-specific W-4 form. Employees should complete the federal Form W-4 and write:

“For New Mexico Withholding Tax Only” across the top of the form before submitting it to their employer.

Recommendation: File Electronically Using TAP

The New Mexico Taxation and Revenue Department recommends electronic filing through the Taxpayer Access Point (TAP) portal or approved tax software. Electronic filing offers several advantages:

• Faster processing and refunds
• Immediate confirmation of receipt
• Reduced errors through automated checks
• Secure online payments and account management
• Easy access to prior-year filings and correspondence

For both individuals and businesses, electronic filing is the most efficient, accurate, and secure way to meet New Mexico tax filing requirements.
