Types of Trusts for Married Couples in 2026, Explained

What Are the Main Types of Trusts for Married Couples?

The core trusts married couples use are revocable living trusts (joint or separate), testamentary trusts, A-B or bypass trusts, marital and QTIP trusts, spousal lifetime access trusts (SLATs), irrevocable life insurance trusts (ILITs), special needs trusts, and qualified domestic trusts (QDOTs). Most couples need only one or two of these, and many need none beyond a basic living trust.

Every trust has three roles. The grantor (also called the settlor or trustor) creates the trust and usually contributes the assets. The trustee holds legal title and manages the assets under the trust's terms. The beneficiaries are the people entitled to benefit from the trust. In a typical living trust, a married couple fills all three roles during their lifetimes. These definitions come from IRS trust basics.

Revocable vs. irrevocable, living vs. testamentary

Two questions sort almost every trust:

• Can it be changed? A revocable trust can be amended or revoked by the grantor. An irrevocable trust, by its terms, generally can't be modified, amended, or revoked. If a trust document is silent on revocability, most states treat it as revocable.
• When does it start? A living (inter vivos) trust is created during your lifetime. A testamentary trust is created by your will, comes into existence at death, is irrevocable by definition, and generally goes through probate because the will does.

You may not need a trust at all

A will can leave any amount to a U.S. citizen spouse free of federal estate tax, thanks to the unlimited marital deduction in Internal Revenue Code § 2056. If your only goal is to leave everything to your spouse, a will is generally simpler and less expensive. Trusts earn their cost when you want to avoid probate, plan for incapacity, control who inherits after your spouse, or reduce estate tax on a larger estate.

Joint vs. Separate Revocable Living Trusts for Married Couples

A joint revocable living trust puts both spouses' assets under one document with both of you as co-trustees. Separate trusts give each spouse sole control over their own share and their own beneficiaries. Both avoid probate equally well. The real difference shows up after the first spouse dies.

With a joint trust, the surviving spouse usually keeps full control and can amend or revoke the whole trust. With separate trusts, the deceased spouse's trust typically becomes irrevocable at death, which locks in that spouse's chosen beneficiaries. LegalClarity's overview notes that separate trusts tend to matter most for couples with children from prior relationships or significant premarital assets.

What a revocable trust does well

• Probate avoidance. Assets titled in the trust generally pass without probate court, which saves time and keeps your affairs private.
• Incapacity planning. If one spouse becomes unable to manage finances, a co-trustee or successor trustee can step in without a guardianship or conservatorship proceeding. Spell out exactly what triggers that handoff, such as a written determination from one or two physicians.
• Simple taxes. The IRS treats a revocable living trust as a grantor trust, so income is generally reported on your own return.

What it doesn't do

A revocable trust provides no estate tax benefit and no lifetime creditor shield, because you keep control of the assets. Creditors can generally reach trust assets during the grantors' lives. The trust also only works for assets you actually move into it, so funding (retitling deeds, accounts, and investments in the trust's name) is a required step, not an optional one.

Community vs. separate property inside the trust

How an asset was classified before it went into the trust carries over. Community property keeps its shared status in a joint trust, while separate property (owned before marriage, gifted, or inherited individually) can lose that status if it gets mixed with marital funds. A clear asset schedule that labels each item as community, marital, or separate gives you both clarity later.

Classification also affects taxes. In the nine community property states, both halves of community property generally receive a new tax basis at the first spouse's death under IRC § 1014. In separate property states, only the deceased spouse's half does. Picture a property bought for $1 million and now worth $2 million. In a common law state, the survivor's basis might become $1.5 million, leaving a $500,000 taxable gain on a sale. With community property treatment, the full basis can step up to $2 million.

How Bypass, Marital, and QTIP Trusts Work After the First Spouse Dies

Bypass, marital, and QTIP trusts are usually written into a couple's plan in advance and take effect at the first death. They divide assets so that both spouses' exemptions and the first spouse's beneficiary choices carry forward after that death.

The A-B split

In an A-B plan, the couple's trust divides at the first death:

• Trust A (survivor's or marital trust) holds the surviving spouse's share and generally stays revocable.
• Trust B (bypass or credit shelter trust) receives the deceased spouse's share, up to the federal exemption amount, and becomes irrevocable.

The survivor can receive income from Trust B and, if the document allows, principal for health, education, maintenance, and support (often abbreviated HEMS). The survivor can't change who ultimately inherits, and the Trust B assets, including growth, stay outside the survivor's taxable estate.

The QTIP trust

A qualified terminable interest property (QTIP) trust is defined in 26 U.S.C. § 2056(b)(7). The surviving spouse must be entitled to all of the trust's income, paid at least annually, and no one can have a power to appoint the property to anyone other than the surviving spouse during that spouse's life. In exchange, the trust qualifies for the marital deduction, and the first spouse decides who receives what remains.

The executor makes the QTIP election on the estate tax return, and the statute says that election is irrevocable once made. Estate tax is generally deferred until the surviving spouse's death, when the QTIP assets are counted in that spouse's estate.

Portability vs. bypass vs. QTIP

Portability is the simpler route for many couples, but it isn't automatic. The executor has to file Form 706 within nine months of death, or by the end of a six-month extension, even if no tax is owed. For estates that weren't otherwise required to file, Rev. Proc. 2022-32 allows a simplified late election on or before the fifth anniversary of the death. Missing that window can mean losing the unused exemption permanently.

A bypass trust, by contrast, becomes its own taxpayer. Non-grantor trusts generally file Form 1041 for any year with $600 or more of income, and assets often need to be valued at the date of the first death.

The 2026 exemption context

The IRS confirms that Public Law 119-21 set the federal basic exclusion amount at $15,000,000 for 2026, up from $13,990,000 in 2025. The federal estate tax rate above the exemption is a flat 40%. The exemption has changed many times since 2011, and future legislation could change it again. Some states also impose their own estate taxes, with exemptions that have been as low as $1 million, so a couple well under the federal threshold may still face a state-level tax.

Irrevocable Lifetime Trusts Couples Use: SLATs, ILITs, and Special Needs Trusts

SLATs, ILITs, and special needs trusts are irrevocable trusts funded during life for specific goals: moving future growth out of a taxable estate, holding life insurance, or supporting a family member with a disability. Because they're irrevocable, they trade flexibility for those benefits.

Spousal lifetime access trust (SLAT)

In a SLAT, one spouse funds an irrevocable trust for the benefit of the other spouse. The assets, and their future growth, leave the grantor spouse's taxable estate, while the couple keeps indirect access through the beneficiary spouse. The tradeoff is that this access depends on the beneficiary spouse. Because the trust is irrevocable, its terms generally can't be rewritten later, so couples should discuss with an estate planning attorney how the trust would work if the beneficiary spouse dies first or the marriage ends.

Irrevocable life insurance trust (ILIT)

An ILIT owns a life insurance policy so the death benefit can stay outside your taxable estate. It can also give heirs cash to pay taxes or settlement costs without selling a family business or real estate. Once assets go in, an ILIT is difficult to change.

Special needs trust

A special needs trust lets you leave money to a child, sibling, or other loved one with a disability without disqualifying them from means-tested benefits such as Supplemental Security Income (SSI) and Medicaid. The funds can pay for housing, education, equipment, care, and quality-of-life expenses. The drafting has to meet technical federal and state benefit rules, so this is a document to have prepared by an attorney familiar with those programs.

Other tools for larger estates

Couples well above the exemption sometimes add intentionally defective grantor trusts (IDGTs), grantor retained annuity trusts (GRATs), or dynasty trusts designed to hold assets across several generations. These are specialized strategies and usually involve both an attorney and a tax professional.

Lifetime gifting also plays a role. For 2026, the annual gift exclusion is $19,000 per recipient, or $38,000 when both spouses give to the same person. Gifts to a U.S. citizen spouse are generally not taxable gifts.

Trusts for Blended Families, Non-Citizen Spouses, and Community Property Planning

Second marriages, non-citizen spouses, and state property rules often change which trust structure fits best. Each of these situations has its own rules that a standard joint trust doesn't address.

Blended families

Roughly two-thirds of people who divorce go on to remarry, so planning for children from a prior relationship is common. Separate revocable trusts, a QTIP trust, or a bypass trust can let one spouse provide for the surviving partner while keeping the plan for their children in place. In a QTIP trust, for example, your spouse receives income for life, and the remainder then passes to the beneficiaries you named.

Non-citizen spouses and the QDOT

The unlimited marital deduction generally isn't available for property passing to a spouse who isn't a U.S. citizen unless it goes into a qualified domestic trust under 26 U.S.C. § 2056A. Key rules:

• At least one trustee must be an individual U.S. citizen or a domestic corporation, with the right to withhold the tax from principal distributions.
• Distributions of principal during the surviving spouse's life are generally subject to estate tax.
• Income distributions and distributions made for hardship (an immediate and substantial need for health, education, maintenance, or support) are exempt.
• Property remaining at the surviving spouse's death is taxed, and the trustee reports it on Form 706-QDT.

If the surviving spouse later becomes a U.S. citizen and meets certain conditions, the QDOT tax can stop applying to future distributions. For lifetime planning, the 2026 annual exclusion for gifts to a non-citizen spouse is $194,000.

Opt-in community property trusts

Alaska, Florida, Kentucky, South Dakota, and Tennessee let married couples elect to have trust assets treated as community property, even if they live elsewhere. Greenleaf Trust explains that this can allow a full 100% basis step-up at the first death rather than the 50% adjustment typical in common law states. Common requirements include:

• A signed election by both spouses
• A conspicuous notice about the consequences, including creditor claims and divorce
• A qualifying in-state or corporate trustee in most of these states

The tradeoffs are real. Opting in can mean giving up separate-property claims in a future divorce, and in Florida a creditor of one spouse can reach up to 50% of the trust's assets. Retirement accounts such as IRAs and 401(k)s generally don't benefit from this basis planning.

Trust rules and even the legal definition of spouse vary by state. The Uniform Law Commission publishes a model Uniform Trust Code that states can adopt and adapt, so your state's version controls the default rules.

How Trusts and Prenups Work Together for Couples

A prenup outlines how a couple classifies and divides property during the marriage and if it ends. A trust governs how titled assets are managed and passed at incapacity or death. Many couples use both, and the two documents work best when they agree with each other.

Keep your definitions consistent

If your prenup says an inherited brokerage account is separate property, your trust's asset schedule should label it the same way. Conflicting descriptions invite confusion later, and commingling separate funds with marital funds can blur classification no matter what either document says.

Topics couples may want to address in both documents include:

• Premarital assets and expected inheritances
• How a SLAT or other irrevocable trust fits into your property plan if the marriage ends
• Whether to elect an opt-in community property trust, given its effect on separate-property claims
• Beneficiaries for children from prior relationships

No single clause guarantees a particular outcome, because state law and the specific drafting control how each document is read.

Approach it as a shared conversation

Talking through inheritances, prior children, and what happens at a death or divorce can feel heavy. It helps to treat it as financial planning you're doing together. As Michael C. Cotugno, Esq., Managing Partner at Neptune Legal, puts it: "True strength in any relationship comes not from avoiding uncomfortable truths or difficult conversations, but from confronting them with courage, compassion, and an unwavering commitment to clarity and mutual respect."

When to bring in professionals

A first conversation about your goals doesn't require a lawyer. Specific steps do. Irrevocable trusts, QTIP and QDOT elections, Form 706 portability filings, and opt-in community property trusts call for an estate planning attorney and often a CPA or enrolled agent. For the prenup itself, independent counsel for each partner is highly recommended for an enforceable prenup.

Couples drafting a prenup can work with a lawyer-led online prenup service such as Neptune. When both partners use Neptune-network lawyers, each partner has their own independent attorney and chooses that attorney. Coordinating the prenup with your estate planning attorney's trust documents helps both agreements reflect the same plan.
