New Mexico-Specific Tax Strategies
These strategies are especially powerful or unique in New Mexico. Click any strategy to learn more.
New Mexico's PTET election allows pass-through entities to pay state income tax at the entity level. Owners receive a credit on their individual returns while the entity deducts the payment federally.
New Mexico allows a deduction of up to 50% of net capital gains from the sale of New Mexico assets. This effectively cuts the state capital gains rate in half for qualifying transactions — a significant benefit for business owners and real estate investors.
Section 179 allows businesses to deduct the full purchase price of qualifying equipment, vehicles, and software in the year of purchase rather than depreciating over time. The 2026 federal limit is over $1 million. Some states cap or limit Section 179 conformity — check your state rules.
S-Corp owners must pay themselves a "reasonable salary" subject to payroll taxes (15.3%), but remaining profits distributed as shareholder distributions avoid self-employment tax entirely. Optimizing the salary-to-distribution ratio is one of the most impactful tax strategies for business owners earning $60,000+ in net profit.
The home office deduction (IRC §280A) allows self-employed individuals and business owners to deduct a portion of rent, mortgage interest, utilities, insurance, and repairs based on the percentage of your home used exclusively for business. The simplified method allows $5/sq ft up to 300 sq ft ($1,500 max).
Choosing the right business structure is the single biggest tax decision you'll make. Here's what New Mexico LLC and S-Corp owners need to know.

New Mexico LLCs are taxed as pass-through entities by default. All profits flow to your personal return and are taxed at 5.9%. Electing S-Corp status can significantly reduce your self-employment tax burden.
