The Basics
What Cost Segregation Does for New Mexico Property Owners
A cost segregation study identifies building components HVAC systems, specialty flooring, parking surfaces, interior finishes, exterior lighting that qualify for accelerated depreciation on 5-, 7-, or 15-year schedules rather than the default 27.5-year (residential rental) or 39-year (commercial) building schedule. Front-loading those deductions increases first-year cash flow and lowers current-year taxable income.
In New Mexico, timing matters. For tax years beginning on or before December 31, 2026, New Mexico conforms to federal §168(k) bonus depreciation meaning federal 100% bonus depreciation (restored by the One Big Beautiful Bill, OBBBA, P.L. 119-21 for property placed in service after January 19, 2025) flows through to your New Mexico return. Starting with tax years beginning January 1, 2027, New Mexico SB 151 (signed March 11, 2026) decouples New Mexico from both §168(k) and §168(n) qualified production property. Property placed in service in 2026 keeps the full federal + state stacking benefit; property placed in service in 2027 and later will be subject to the New Mexico addback going forward.
2026 Window: Federal + State Stack; 2027+ Federal Only
New Mexico’s Tax Landscape: Why Cost Segregation Delivers Full Federal + State Benefit Here (2026)
Individual Income Tax
Graduated with 5 brackets from 1.5% to 5.9% top (New Mexico Taxation and Revenue Department). N.M. also provides a 50% capital gains deduction on New Mexico-source capital gains.
Corporate Income Tax
5.9% flat (moved from a graduated structure to a flat rate in 2025).
Bonus Depreciation Conformity (2026)
Full conformity to federal §168(k) federal 100% bonus flows through. Effective for tax years beginning on or after January 1, 2027, SB 151 decouples New Mexico from §168(k) and §168(n), creating an addition modification for amounts exceeding regular MACRS.
§179 Expensing
New Mexico conforms to federal §179 as amended. The 2026 §179 cap is $2.56M (indexed from OBBBA’s $2.5M) with a $4.09M phase-out threshold.
§163(j) Interest Expense (2027+)
SB 151 also modifies New Mexico’s §163(j) calculation to use EBIT (not EBITDA) starting 2027 additional decoupling from OBBBA.
NCTI (Formerly GILTI)
SB 151 adds NCTI to the New Mexico corporate tax base starting 2027.
Gross Receipts Tax (GRT)
New Mexico uses a Gross Receipts Tax (~4.875% state rate plus local increments) instead of a sales tax. Applies to services as well as tangible goods.
Property Tax
~0.63% effective on owner-occupied housing among the lower rates in the country. A separate lever from income tax.
§481(a) Catch-Up
For New Mexico properties owned more than a year without a study, an automatic accounting-method change (Form 3115 under Rev. Proc. 2015-13 and its updates) captures all missed depreciation into the current tax year at the federal level no amended returns required.

Real Numbers
What First-Year Savings Might Look Like in New Mexico
Results depend on property type, cost basis, construction year, and applicable depreciation rates and we run a free benefit analysis before you commit to a study so you can see projected numbers first.
As a reference point, an Ambrose Group engagement on a $2.9M commercial property delivered $657,692 in first-year depreciation increase and $230,192 in first-year tax savings. In New Mexico specifically, for property placed in service in 2026, both the federal 100% bonus depreciation and New Mexico’s conforming state-level bonus depreciation apply delivering full Year 1 stacking at both levels. At New Mexico’s 5.9% top individual and 5.9% flat corporate rates, the combined federal + state benefit is substantial. Property placed in service in 2027 and later will see the federal benefit only, with New Mexico requiring an addback under SB 151.

Frequently Asked Questions
Does New Mexico conform to federal bonus depreciation rules?
For tax years beginning on or before December 31, 2026, yes New Mexico conforms to federal §168(k) bonus depreciation, and the 100% bonus depreciation restored by OBBBA applies at both federal and New Mexico state levels. However, SB 151 (signed March 11, 2026) decouples New Mexico from §168(k) and §168(n) effective for tax years beginning January 1, 2027. This creates a strategically important tax planning window for property placed in service in 2026.
How does New Mexico’s income tax structure interact with a cost segregation study?
New Mexico has a graduated individual income tax with a top rate of 5.9% (five brackets from 1.5%) and a flat 5.9% corporate income tax (moved from graduated in 2025). For 2026, both Year 1 federal and state benefits apply. New Mexico also provides a 50% capital gains deduction on New Mexico-source capital gains favorable for eventual property sale planning.
What is New Mexico SB 151 and how does it affect cost segregation?
SB 151 (signed March 11, 2026, effective May 20, 2026 for provisions taking effect that date) decouples New Mexico from federal §168(k) bonus depreciation and §168(n) qualified production property for tax years beginning January 1, 2027. SB 151 also modifies New Mexico’s §163(j) interest expense calculation (from EBITDA-based to EBIT-based) and adds NCTI (formerly GILTI) to the corporate tax base all effective 2027.
What New Mexico commercial property types benefit most from cost segregation?
Albuquerque metro national labs (Sandia) and defense operations (Kirtland AFB), Los Alamos National Laboratory, Intel Rio Rancho semiconductor fab, Permian Basin oil and gas operations, Santa Fe destination hospitality, and Albuquerque-metro multifamily. Highly specialized research and semiconductor operations typically deliver the strongest results due to heavy specialty equipment content.
Can I do a cost segregation study on a New Mexico property I’ve owned for years?
Yes. A §481(a) adjustment via an automatic accounting-method change (Form 3115 under Rev. Proc. 2015-13 and its updates) lets you capture all missed depreciation from prior years into the current tax year without amending past returns. Especially valuable for long-held New Mexico industrial, hospitality, and multifamily properties.
How do you do a cost segregation study on a New Mexico property when you’re based in Texas?
Cost segregation is governed by federal tax law, so the methodology is identical regardless of state. Our engineer works either through an in-person New Mexico site visit or, for well-documented properties, a virtual site inspection using high-definition video, construction documents, and interactive tools. Both are IRS-compliant. New Mexico’s proximity to our Texas headquarters (particularly southeast NM’s Permian Basin operations) makes on-site visits efficient.
What construction era of New Mexico property produces the strongest cost segregation outcomes?
Properties placed in service since 1987 are eligible under current IRS guidance, and studies limited to the last 7–10 years tend to deliver the strongest ROI. New Mexico’s semiconductor expansion (Intel), data center buildout (Meta Los Lunas), Permian Basin operations, and Albuquerque-metro multifamily development have produced substantial newer commercial property in the ideal window.
Does New Mexico’s Gross Receipts Tax affect the cost seg decision?
Not directly. Cost segregation reduces income tax through accelerated depreciation. New Mexico’s Gross Receipts Tax (GRT, ~4.875% state plus local increments) applies to gross receipts from services and goods and operates on a different tax base than income tax.
What documentation do you need for a New Mexico cost segregation study?
Purchase or construction cost documentation, a current depreciation schedule from your CPA, construction plans or specs (when available), any prior appraisals, and for renovation studies improvement records. Given the 2026-vs-2027 SB 151 transition, your CPA will need the detailed asset schedule to model both current and post-decoupling treatment. We provide it as part of the standard deliverable.
Can you handle New Mexico multi-property portfolios? How long does a study take?
Yes,we regularly run cost segregation studies across multi-state and New Mexico-only portfolios. Common for Albuquerque and Los Alamos defense/lab-adjacent operators, Permian Basin operators with multiple field facilities, and Albuquerque-metro multifamily portfolio owners. Typical study timeline is 4–8 weeks per property; complex national lab and semiconductor facilities take longer proportional to the specialty-equipment cataloging effort.
