New Mexico rules for construction & trades
- State income tax (2026)
- New Mexico has a graduated state income tax for 2026: 1.5% to 5.9% (top rate starts at $210,000 for single filers). Single brackets: 1.5% to $5,500; 3.2% to $16,500; 4.3% to $33,500; 4.7% to $66,500; 4.9% to $210,000; 5.9% above $210,000. This six-bracket table has applied since January 1, 2025. The Taxation and Revenue Department's January 27, 2026 bill analysis lists it as the current table. We found no 2026 rate change.
- State estimated tax
- Anyone who must file a New Mexico return has to pay estimated tax. TRD computes an underpayment penalty when the tax on the return exceeds estimated payments plus withholding by more than $1,000. The required annual payment is the lesser of 90% of current-year tax or 100% of prior-year tax. Same dates as federal (April 15, June 15, September 15, January 15). Form PIT-ES.
- New Mexico gross receipts tax (GRT)
- GRT applies to receipts from selling property and performing services in New Mexico, including a freelancer's or independent contractor's fees, with no deduction for business expenses. The state portion has been 4.875% since July 1, 2023, plus county and city rates. The combined rate depends on location and is usually passed on to customers.
- Independent contractor pay is subject to GRT (TRD classification rule)
- TRD treats pay received by independent contractors as subject to gross receipts tax unless an exemption or deduction applies, while employee wages are exempt. TRD accepts the IRS determination of whether a worker is an employee or an independent contractor.
- State retirement program
- New Mexico Work and $ave has been enacted. It is built around W-2 employers and does not cover 1099 contractors through the employer mandate; self-employed residents can enroll on their own.
Federal rules for 2026
W-2 or 1099 changes everything
On a W-2 your employer withholds tax and may offer a retirement plan. As a 1099 subcontractor you pay self-employment tax and quarterly estimates, but you can deduct tools, materials and job-site driving.
Tools and equipment
Tools, equipment, safety gear and work vehicles used for business are deductible; larger purchases can often be written off in the year you buy them.
Overtime deduction for W-2 workers
Non-exempt W-2 workers can deduct the overtime premium they are paid, up to $12,500 a year ($25,000 joint) from 2025 through 2028, subject to an income phase-out.
Quarterly estimated taxes
No one withholds tax from self-employment income, so you generally pay estimates four times a year if you expect to owe $1,000 or more. For 2026 income the federal dates are April 15, June 15 and September 15, 2026, and January 15, 2027. Paying 100% of last year's tax (110% if your AGI was over $150,000) in four equal installments avoids the underpayment penalty.
