Tax Law ✦ Trust & Estate Tax Planning
New Mexico Is Quietly a Great Place to Die Rich. Plan Like It.
No state estate tax, no inheritance tax, and community property rules that hand surviving spouses a full basis step-up most states can’t match. The families who lose money here lose it to poor planning, not to the tax code. North Star Law Firm builds estate plans where the tax analysis and the documents come from the same attorney-CPA.
Overview
What does New Mexico get right for estates?
Three structural advantages. First, New Mexico imposes no estate or inheritance tax, so the only transfer tax conversation is federal, and with the federal exemption at $15 million per person starting in 2026 under the 2025 tax law, most New Mexico families will never owe a dollar of estate tax. Second, New Mexico is a community property state, which delivers the most underrated income tax benefit in the code: under I.R.C. § 1014(b)(6), when the first spouse dies, both halves of community property step up to fair market value, not just the decedent’s half. A couple’s $800,000 rental portfolio bought decades ago for $200,000 can be sold by the survivor with little or no capital gain. Third, the 2023 exemption overhaul and solid trust statutes make asset protection planning realistic without leaving the state. The planning question for most families here is no longer estate tax avoidance; it is income tax basis, control, and keeping the plan from breaking the family.
- Revocable living trusts and probate-avoidance done right
- Community property agreements that lock in the double step-up
- Basis-focused planning: when NOT to gift is half the advice
- Irrevocable trusts, gifting programs, and 709 compliance
- Business succession for LLCs, S corps, ranches, and rentals
- Fiduciary income tax returns and trust administration support
The Law
Step-up or gift: which saves the family more?
The old reflex, give assets away early, is now frequently wrong. Gifted assets carry your old basis to the recipient under I.R.C. § 1015; inherited assets take a fresh fair-market-value basis under § 1014. With a $15 million exemption, holding appreciated assets until death often beats gifting them, and in a community property state the arithmetic doubles.
| Move | Transfer tax effect | Income tax effect |
|---|---|---|
| Hold until death (community property) | Uses exemption, rarely exhausted | Full step-up on both halves; gain evaporates |
| Lifetime gift of appreciated asset | Uses exemption or annual exclusion | Carryover basis; recipient inherits your gain |
| Gift of cash or high-basis assets | Same exemption use | No gain problem; usually the better gift |
| Sale to grantor trust / GRAT-style freeze | Freezes future growth outside the estate | Basis planning must be engineered deliberately |
None of this is one-size advice. Families above the exemption, or with property in states that do tax estates, still need freeze and gifting strategies. The point is that the default has flipped, and plans drafted in the era of low exemptions deserve a rereading before they quietly cost the children a fortune in capital gains.
Do you actually need a trust in New Mexico?
Usually yes, but for the honest reasons. New Mexico’s probate process is comparatively manageable, so the trust case here is less about dodging a nightmare court process and more about incapacity management, privacy, controlling distributions to young or vulnerable beneficiaries, real estate in multiple states, and keeping a business running without interruption. A revocable living trust does none of the tax work people imagine, it is ignored for income and estate tax while you live, but it is the right chassis for almost every plan. The tax machinery lives in the irrevocable layer: spousal lifetime access trusts, irrevocable life insurance trusts where estate tax is a live risk, and grantor trusts that let you pay the trust’s income tax as an additional, exemption-free gift.
What about the family business, the ranch, the rentals?
Succession is where estate planning stops being documents and becomes tax engineering. Who gets control versus who gets value; whether the S corporation’s stock can pass to that trust without blowing the election, only certain trusts qualify, and the QSST and ESBT elections have deadlines; how a ranch that is land-rich and cash-poor pays any tax that does come due, where installment relief under § 6166 and conservation easement strategies enter; and how the operating agreement’s transfer restrictions interact with the estate plan signed years later. These documents are usually drafted by different professionals who never meet. Here they are drafted, and stress-tested against the tax return, together, alongside the entity questions covered on our entity structuring page.
What does trust administration look like after a death?
The part nobody budgets for. Trustees must marshal and value assets, obtain date-of-death appraisals that support the step-up, decide whether a federal estate tax return is worth filing even when no tax is due, portability of a deceased spouse’s unused exemption requires a timely Form 706, and file fiduciary income tax returns for the trust or estate under the compressed trust tax brackets. Trustees who guess get personal exposure, a topic our Houston practice writes about often, and the survivors lose deductions and elections that never come back. We handle administration start to finish, including the returns.
The Attorney-CPA Difference
Estate plans fail on the tax details. Ours are built from them.
- Basis modeling before any gift: step-up value versus exemption use, in dollars
- Community property agreements coordinated with titling and beneficiary forms
- S corporation and partnership succession without blown elections
- Forms 706, 709, and 1041 prepared by the planner, not handed off
Questions & Answers
Estate planning questions, answered
Does New Mexico have an estate or inheritance tax?
No. Neither. The only transfer tax in play is federal, and with the exemption at $15 million per person from 2026, it touches very few New Mexico families. The bigger tax issue in most plans is capital gains basis, which is exactly where community property helps.
What is the community property double step-up in plain terms?
If you and your spouse own appreciated property as community property, the entire property, not just half, resets to market-value basis when the first of you dies. The survivor can sell with little or no capital gain. Couples who moved here from separate-property states often need a community property agreement to capture this, and it is one of the highest-value documents we draft.
We moved from Texas with an old trust package. Is it still good?
Texas is also community property, so the core often travels well, but state law references, trustee provisions, and any planning built for the old lower exemptions should be reviewed. Plans built around aggressive gifting a decade ago frequently now cost more in lost basis than they save in estate tax.
Should I add my kids to the deed instead of doing a trust?
Almost never. Adding children to title is a lifetime gift of carryover-basis property, exposes the home to their creditors and divorces, and can forfeit both the step-up and homestead protections. A transfer-on-death deed or trust gets the convenience without those costs.
Who pays income tax on a trust’s earnings?
It depends on the trust. Revocable trusts are ignored: you pay. Grantor trusts: the grantor pays, often deliberately. Non-grantor trusts pay at compressed brackets that hit the top federal rate around $16,000 of retained income, which is why distribution planning between the trust and beneficiaries is an annual exercise, not a set-and-forget.
The plan you sign should still work the day it’s needed.
Bring the deeds, the old trust, and the business documents. You will leave with a clear map of what steps up, what gets taxed, and what to change while changing it is easy.
