Low-and-middle-income exemption

Local income tax

• 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.

1. Start with federal AGI → PIT-1
2. Add NM additions — items NM adds back
3. Subtract NM subtractions — items NM excludes
4. Subtract NM exemptions (low-and-middle-income exemption, blind/aged exemptions)
5. Subtract standard or itemized deductions (NM follows federal amounts)
6. Result = NM taxable income
7. Apply the graduated rate schedule → NM tax
8. Apply credits and rebates (Schedule PIT-CR) → final tax due or refund

Key addition modifications

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

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

• 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

• Estimated tax threshold — NM requires estimated tax payments if you expect to owe $1,000 or more after subtracting withholding and credits.

Estimated tax installment due dates

Installment	Due date
1st quarter	April 15
2nd quarter	June 15
3rd quarter	September 15
4th quarter	January 15 (following year)

Form PIT-ES is used for estimated tax payments.

Gross Receipts Tax (GRT) interaction

• 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 Working Families Tax Credit — 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.

Section 5: Tier 1 rules — deterministic

• NM-T1-01 — NM taxable income = federal AGI ± NM modifications − exemptions − deductions (N.M. Stat. Ann. §7-2-2)
• NM-T1-02 — Tax computed using 6-bracket schedule: 1.5%–5.9% (TY 2025) (N.M. Stat. Ann. §7-2-7; HB 252)
• NM-T1-03 — Starting point is federal AGI (Form 1040, Line 11) (N.M. Stat. Ann. §7-2-2)
• NM-T1-04 — Social Security benefits fully exempt (N.M. Stat. Ann. §7-2-2(S))
• NM-T1-05 — Low-and-middle-income exemption: up to $2,500 per qualified exemption (N.M. Stat. Ann. §7-2-5.6)
• NM-T1-06 — NM Working Families Tax Credit = 25% of federal EIC (refundable) (N.M. Stat. Ann. §7-2-18.16)
• NM-T1-07 — Estimated tax required if expected liability ≥ $1,000 (N.M. Stat. Ann. §7-2-12.2)
• NM-T1-08 — NM follows federal standard deduction amounts (N.M. Stat. Ann. §7-2-2)

Section 6: Tier 2 rules — requires judgment

• NM-T2-01 — Multi-state income: Taxpayer has income from another state (NM taxes worldwide income of residents. Credit for taxes paid to other states available on Schedule PIT-CR.)
• NM-T2-02 — GRT vs. income tax interaction (GRT is a separate tax on gross receipts, not a credit against income tax. GRT paid is deductible as a business expense on federal Schedule C, which flows through to NM.)
• 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.)
• NM-T2-05 — 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.)
• NM-T2-06 — Community property (New Mexico IS a community property state. MFS returns require community property income allocation.)
