Low-and-middle-income exemption
New Mexico offers a low-and-middle-income exemption of up to $2,500 per qualified exemption, based on adjusted gross income. All taxpayers (residents, part-year residents, nonresidents) may claim this exemption.
Local income tax
New Mexico does not permit local income taxes.
Section 3: How this skill works with the federal return
New Mexico taxable income starts with federal adjusted gross income (FAGI) from federal Form 1040, Line 11.
- Start with federal AGI → PIT-1
- Add NM additions — items NM adds back
- Subtract NM subtractions — items NM excludes
- Subtract NM exemptions (low-and-middle-income exemption, blind/aged exemptions)
- Subtract standard or itemized deductions (NM follows federal amounts)
- Result = NM taxable income
- Apply the graduated rate schedule → NM tax
- Apply credits and rebates (Schedule PIT-CR) → final tax due or refund
Key addition modifications
| Addition |
Description |
| Lump-sum distributions |
Certain lump-sum distributions not included in federal AGI |
| NM income not in federal AGI |
Income taxable by NM but excluded from federal return |
Key subtraction modifications
| Subtraction |
Description |
| US government bond interest |
Interest from US Treasury obligations |
| Social Security |
NM does not tax Social Security benefits |
| Military retirement pay |
Exempt for certain qualifying individuals |
| Age 65+ income exemption |
Up to $8,000 for 65+ with AGI under $51,000 (single) or $36,667 (MFJ per spouse) |
Section 4: Self-employed specific rules
Self-employment income flow
Schedule C net profit flows into federal AGI, which is the starting point for NM. NM follows the federal self-employment tax deduction (deductible half of SE tax) through federal AGI.
Estimated tax
NM requires estimated tax payments if you expect to owe $1,000 or more after subtracting withholding and credits.

| 1st quarter |
April 15 |
| 2nd quarter |

Form PIT-ES is used for estimated tax payments.
Gross Receipts Tax (GRT) interaction
Self-employed taxpayers in NM are also subject to the Gross Receipts Tax (GRT), which is NM's equivalent of a sales/use tax but is imposed on the seller's gross receipts. Unlike a traditional sales tax, the GRT is imposed on the business (not the buyer), though it is commonly passed through to customers.
- GRT applies to most services as well as goods (unlike most state sales taxes).
- Rates vary by location (combined state + local: approximately 5.0% to 9.4375%).
- Self-employed service providers must register for and collect/remit GRT.
- GRT paid is deductible as a business expense on the federal Schedule C.
Working Families Tax Credit (NM EIC)
NM offers a refundable earned income credit equal to 25% of the federal Earned Income Credit (EIC) for TY 2025. This is particularly valuable for lower-income self-employed taxpayers.

| NM-T2-03 |
Technology jobs tax credit |
NM offers credits for qualifying technology businesses. Requires certification. |
| NM-T2-04 |
Angel investment credit |
NM allows credits for qualified investments in NM small businesses. Requires approval from NM Economic Development Department. |

Federal IRC conformity |
NM's conformity with the IRC should be verified for recent federal changes. NM generally has rolling conformity but may decouple from specific provisions. |

Community property |
New Mexico IS a community property state. MFS returns require community property income allocation. |
