How do state-specific estate laws affect your estate plan when you change residence?

Moving to a new state can change which laws apply to your estate—sometimes dramatically. State rules control whether your estate owes a state-level estate tax or an inheritance tax, how probate works, where a will is admitted, and how real property is treated. Small changes in domicile, property titling, or timing can convert a plan that worked well in one state into a costly or administratively difficult one in another.

Below I explain the practical differences, the most common traps I see in practice, and a clear checklist to act on before and after you move. This guidance is educational; consult a qualified estate planning attorney and tax advisor licensed in the state you plan to live in for tailored advice.

Why residence and domicile matter

Two legal ideas are key: residency and domicile. Residency is often a factual matter (where you live most of the year), while domicile is your legal home—the place you intend to return to permanently. States use these concepts differently for estate and inheritance rules, income tax, and probate jurisdiction. Establishing domicile in a state with an estate tax, or owning real estate there, may pull your estate into that state’s legal and tax net even if you spend parts of the year elsewhere.

Key state-level differences that change outcomes

  1. Estate tax vs. inheritance tax
  • Estate tax: levied on the deceased person’s estate before distributions. A state estate tax reduces the amount available to heirs. Some states impose their own estate taxes, often with exemptions far lower than the federal exemption.
  • Inheritance tax: levied on the recipient (heir) based on relationship and the value received. Rates and exemptions usually depend on the heir’s relationship to the decedent.

Practical effect: moving from a state with no estate or inheritance tax into a state that taxes estates (or vice versa) can change expected net inheritances and may require different planning tools.

  1. Probate law and small-estate procedures
    States vary in how long probate takes, who qualifies to use small-estate transfer procedures, and whether they recognize simplified forms or summary administration. For families who need liquidity quickly (to pay mortgages, taxes, or business obligations), longer probate can create cash-flow problems.

  2. Real property situs and ancillary probate
    Real estate is governed by the law where the property sits. If you die owning real estate in State A but are domiciled in State B, the property usually requires ancillary probate in State A, adding complexity and cost.

  3. Community property and spousal rights
    Community property, elective share, and surviving-spouse rules differ by state. Community property rules (in nine states) affect basis step-up calculations and estate tax planning; elective-share statutes define a surviving spouse’s guaranteed portion regardless of the will.

  4. Creditor claims and homestead protections
    Homestead, creditor exemptions, and how quickly creditors must present claims in probate vary. These protections can matter for heirs and for whether a family home can be kept during administration.

When you move: immediate steps to reduce surprises

  1. Confirm your domicile and residency facts
    Document your intent: update driver’s license, voter registration, tax returns, primary bank, and professional licenses. Courts weigh multiple factors when deciding domicile; a consistent paper trail helps if the residency question arises.

  2. Inventory assets and check situs
    Identify real estate, retirement accounts, life insurance, and business interests. Remember: retirement accounts and life insurance are paid by contract to named beneficiaries and usually bypass probate—but state law still governs income taxation on distributions in some cases.

  3. Review wills, trusts, and beneficiary designations
    A will written in one state is usually valid in another, but its tax and probate consequences will differ. Trusts can simplify administration and sometimes reduce state estate exposure—but they must be drafted and funded with attention to the laws of the state where you live and where your assets sit.

  4. Revisit titling and joint ownership
    How you title property (community property, joint tenants with rights of survivorship, tenancy in common) affects probate and tax. Joint ownership may avoid probate but can have gift-tax, creditor, or unintended-benefit consequences.

  5. Recalculate projected state tax exposure
    Estimate whether a state estate or inheritance tax could apply. Because state thresholds, rates, and exemptions vary, a move can shift liability from zero to material within days or months.

Practical planning strategies (what I do with clients)

  • Use irrevocable life insurance trusts (ILITs) and properly funded irrevocable trusts to remove life insurance proceeds and other assets from taxable estates where state estate taxes are an issue. These can also provide liquidity to pay state estate taxes and probate expenses (see our guide on using life insurance strategically).

  • Consider portability and federal election planning: For married couples, electing portability for the deceased spouse’s unused federal exclusion (where available) is a federal filing issue; state treatment varies, so coordinate federal and state planning.

  • Title real estate intentionally: Before moving, decide whether to keep real property in the original state or sell/transfer it. If you keep it, expect potential ancillary probate.

  • Use resident-state tools: Some states offer enhanced small-estate transfers, transfer-on-death deeds, or probate-avoiding devices—use them where appropriate.

  • Gifting and annual-exclusion strategies: Lifetime gifting can reduce an estate that is subject to state estate taxes, but be mindful of gift tax reporting and state rules on look-back periods for transfers.

Case example (anonymized and composite)

A retired couple moved from Florida (no state estate tax) to New Jersey, intending to spend winters near family. After establishing domicile, their combined assets—mainly a house in New Jersey and investment accounts—brought them within state estate-tax exposure. Using an irrevocable trust to hold certain assets, updating beneficiary designations, and purchasing a life insurance policy owned by an ILIT provided liquidity and reduced taxable estate value. The result: lower projected state estate taxes and a simpler administration for heirs. This sort of planning requires careful timing and coordination with local counsel.

Common mistakes I see

  • Failing to update beneficiary designations after a move. Retirement plan and life insurance beneficiary forms typically control distributions even if estate documents change.

  • Assuming a will or trust written elsewhere removes the need to adjust plans. Laws on spousal rights, elective shares, and community property can override intended distributions.

  • Overlooking ancillary probate for out-of-state real estate. Expect delay and additional legal fees.

  • Relying solely on joint ownership to avoid probate. This can create accidental gifts, tax consequences, or creditor exposure.

Quick checklist before and after a residential move

Before you move

  • Inventory major assets and list where each is located.
  • Consult an attorney in the destination state for initial estate-tax exposure analysis.
  • Review titling and beneficiary designations.

Within 90 days after the move

  • Change your driver’s license and voter registration; update tax withholding as needed.
  • Revisit trusts and wills with local counsel; confirm funding of any trusts.

Ongoing

  • Review your plan after major life events, asset growth, or changes in state law. (See our resource on Updating Your Estate Plan After Major Life Events.)

Frequently asked questions (brief)

  • Do I need a new will if I move? Usually you should review and possibly update it—state laws on execution and spousal rights differ. A will valid where it was signed is often valid elsewhere, but it may not reflect new-state tax or elective-share rules.

  • Will my real estate always require ancillary probate? If you remain domiciled elsewhere and keep real property in another state, most likely yes—unless the new state’s devices (like transfer-on-death deeds) avoid it.

Authoritative references and where to check current rules

Note: State exemptions, rate schedules, and filing rules change frequently. Don’t rely on printed thresholds you read here without confirming on the state revenue site or with local counsel.
