Quick Answer

No. In almost every state, you cannot inherit an IRA through a will instead of the IRA beneficiary designation form. The signed form controls who gets the account, and it overrides the will. A will only directs the IRA when no valid beneficiary form names a living person.

A will feels like the master document of an estate, but for an IRA it usually loses. The IRA custodian pays the person named on the beneficiary designation form, and that contract sits outside the probate court that enforces your will. The immediate consequence is harsh: the money can land with an ex-spouse, a dead person’s estate, or a default heir you never intended, and no one can undo it after death.

The stakes go beyond who inherits. When an IRA falls to the estate because the form is blank or invalid, the heirs lose the slow 10-year payout and get stuck with a fast, tax-heavy 5-year or “ghost life expectancy” schedule instead. About one-third of Americans do not know that beneficiary forms override their will, which is exactly how these accidents happen.

Why a Will Almost Never Controls Your IRA

An IRA is a contract between you and the custodian, such as a bank or brokerage. When you open it, you sign a beneficiary designation that tells the custodian who receives the money at your death. That instruction is a non-probate transfer, meaning it passes directly to the named person and skips the probate court entirely.

A will, by contrast, controls only probate assets — property that has no other transfer instruction attached. Because the IRA already has its own instruction, the will has nothing to act on. The custodian follows the form and ignores the will, even if the will is newer and even if it names a different person.

The consequence is concrete and final. If your form names your brother and your will leaves “all my retirement accounts to my daughter,” the custodian pays your brother. Your daughter has no legal claim, and the executor cannot force a different result. There are no do-overs once the owner dies, which is why estate attorneys call the form the most powerful one-page document most people sign and forget.

A common misconception is that a will, being signed last and witnessed, must outrank an old account form. It does not. The form wins because of how the asset transfers, not because of which document is newer or fancier.

What you should do about it: pull every IRA beneficiary form you have signed, read who is actually listed, and update any that no longer match your wishes. This costs nothing and takes one afternoon.

The Rare Exception: When a Will Can Redirect an IRA

There is a narrow legal exception, and it is the reason this question keeps coming up. A handful of states have adopted a version of the Uniform Probate Code (UPC) that allows certain non-probate assets to be redirected by a will — but only under strict conditions. Even there, IRAs are often excluded, and custodians frequently resist honoring a will over their own form.

To have any chance, the will must specifically identify the IRA by reference, not use vague language like “all my financial accounts.” Courts have repeatedly upheld the old form when the will was general. In the widely cited Greenleaf Trust analysis, an outdated beneficiary designation stayed in force despite the owner stating, days before death, that he wanted his assets split equally among all his children.

The consequence of relying on this exception is litigation. Even in a UPC state, the custodian may pay the form beneficiary and force the disappointed heir to sue, which burns months and legal fees with no guaranteed win. Treating “my state might allow it” as a plan is a gamble, not a strategy.

A misconception here is that living in a UPC state makes the will automatically control the IRA. It does not — the UPC governs probate procedure, and federal contract and tax rules, plus the custodian’s own agreement, still shape the outcome.

What you should do about it: never rely on a will to redirect an IRA. Fix the form itself. If you have already inherited an IRA where the will and form conflict, hire a probate or estate attorney before you accept any distribution.

Divorce, Marriage, and the Automatic Revocation Trap

State law adds another layer that surprises families. Many UPC states have a revocation-on-divorce rule (UPC 2-804) that automatically cancels a gift to a former spouse when a marriage ends, even if the owner never updated the form. So an ex-spouse listed on an old IRA form may be wiped out by operation of law.

But this protection is not nationwide and is not airtight. In one Utah federal case, the court applied the state’s presumption that divorce revokes a former spouse’s beneficiary status unless the divorce decree said otherwise. In states without such a statute, the ex-spouse on the form simply inherits.

The consequence cuts both ways. If you want your ex to inherit and the state revokes it, your intent is defeated; if you forgot to remove an ex and the state does not revoke it, your ex takes the money over your current family. Federal ERISA plans like 401(k)s follow different rules, so do not assume your IRA result matches your workplace plan.

What you should do about it: after any divorce, remarriage, birth, or death in the family, re-sign every IRA beneficiary form. Do not assume state law will fix a stale designation for you.

What Happens When the IRA Defaults to Your Estate

If your form is blank, lost, or names only people who died before you, most custodial agreements send the IRA to your estate by default. The estate then distributes it under your will — which finally gives the will a role, but at a steep tax price.

The core problem is that an estate is a non-designated beneficiary. It is not a living person, so it cannot use the friendly 10-year stretch that individual heirs get. Instead, the IRA must empty under one of two faster schedules, depending on the owner’s age at death.

The 5-Year Rule

If the owner dies before their required beginning date (RBD) — generally April 1 of the year after they turn 73 under current law — and the estate is the beneficiary, the 5-year rule applies. The entire account must be emptied by December 31 of the fifth year after death. No distributions are required in years one through four, so heirs can wait and take it all at the end, but it must be gone by year five.

The consequence is a possible “tax bomb.” Bunching a large traditional IRA into one or two tax years can push the income into higher brackets. The fix is to spread withdrawals across the five available tax years rather than waiting for the final deadline.

The Ghost Life Expectancy Rule

If the owner dies on or after their RBD with the estate as beneficiary, the account uses the owner’s remaining single life expectancy — nicknamed the “ghost life expectancy.” Payments stretch over the years the owner would have had left under IRS tables, which can be longer or shorter than five years.

The consequence depends on the owner’s age. A younger decedent’s ghost schedule may run a decade or more, softening the tax hit; a very old decedent’s may be just a few years, hitting harder. The fix is to calculate the exact factor from the IRS Single Life Table before choosing how to draw the account down.

How This Compares to a Properly Named Beneficiary

The cost of the estate route is clearest when you set it next to a normal beneficiary. Most non-spouse individuals who inherit after 2019 use the SECURE Act 10-year rule, emptying the account by December 31 of the tenth year after death. Starting in 2025, if the owner had already begun RMDs, those heirs must also take annual RMDs in years one through nine.

Outcome When the Form Names a Person	Outcome When the IRA Defaults to the Estate
Individual heir uses the 10-year rule, full decade to draw down	Estate uses the 5-year rule (death before RBD) — emptied in 5 years
If owner had begun RMDs, annual RMDs in years 1–9, balance by year 10	Or ghost life expectancy (death on/after RBD), set by IRS table
Spouse can roll the IRA into their own and delay RMDs	No spousal rollover available through the estate
Income can be spread across 10 tax years to manage brackets	Income compressed into fewer years, risking higher brackets
Account stays out of probate, paid quickly and privately	Account passes through probate, slower and public

Worked Numeric Examples

Numbers make the cost real. Assume a $400,000 traditional IRA in all three cases below, and ignore investment growth to keep the math clean.

Example A — Named individual, 10-year rule. The heir spreads $400,000 evenly: roughly $40,000 per year for 10 years. At a 22% marginal rate, that is about $8,800 of federal tax each year, near $88,000 total, and the steady draw keeps the heir out of higher brackets.

Example B — Estate, 5-year rule. The estate must empty $400,000 by year five. If the heirs wait and take it all in one year, that $400,000 stacks on their other income and can push dollars into the 32% or 35% bracket. Spreading it as $80,000 per year over five years is far better, but it is still double the annual income of the 10-year plan, raising the effective rate.

Example C — Estate, ghost life expectancy. Suppose the owner died at 80 after starting RMDs, with a remaining single-life factor near 10.5 years. The first-year required amount is about $400,000 ÷ 10.5 = roughly $38,000, similar to the 10-year pace. Here the ghost rule is gentler than the 5-year rule — proof that the estate’s tax result swings entirely on the owner’s age at death.

The lesson across all three: naming a living person on the form usually preserves the longest, lowest-tax payout, and that flexibility vanishes the moment the IRA routes through the estate.

Which Situation Applies to You?

Your next move depends on which side of this you are on. Match yourself to one of these:

• You are the IRA owner planning ahead → go fix your beneficiary form today and skip the will entirely for this asset.
• You are an heir and the form names you → you ignore the will; claim the IRA directly from the custodian under the 10-year rule.
• You are an heir and the form is blank or names a deceased person → the IRA likely goes to the estate; expect the 5-year or ghost-life-expectancy rule.
• You are an executor holding a will that conflicts with the form → the form wins in most states; get an attorney before distributing.
• You divorced or remarried recently → check your state’s revocation-on-divorce rule and re-sign the form regardless.

Named Examples

Maria, the divorced saver. Maria divorced in 2018 but never updated her IRA form, which still listed her ex-husband, Tom. Her 2023 will left “everything to my children.” Maria lived in a state without a revocation-on-divorce statute, so at her death the custodian paid Tom the full IRA. Her children inherited nothing from that account, and the will could not save them.

James, the single owner with a blank form. James opened an IRA online and skipped the beneficiary field, assuming his will would handle it. He died at 68. With no living beneficiary, the IRA passed to his estate, triggering the 5-year rule. His sister, the will’s heir, had to empty $250,000 within five years and absorbed a large tax spike instead of the 10-year stretch she would have had if James had named her on the form.

Priya, the careful planner. Priya named her daughter directly on the IRA form and also mentioned the IRA in her will “for clarity.” When Priya died, the custodian paid the daughter under the form, and the will language was simply redundant. The daughter used the 10-year rule, spread withdrawals, and kept her tax bill low — the outcome the form, not the will, delivered.

Mistakes to Avoid

Each error below has a real cost.

• Leaving the beneficiary field blank — the IRA defaults to your estate and loses the 10-year stretch.
• Relying on your will to name IRA heirs — the form overrides it and your intended heir may get nothing.
• Forgetting to remove an ex-spouse — in many states the ex inherits the entire account.
• Never naming a contingent beneficiary — if your primary beneficiary dies first, the IRA falls to the estate.
• Naming “my estate” on purpose — you voluntarily trade the 10-year rule for the 5-year or ghost schedule.
• Assuming your 401(k) and IRA follow the same rules — ERISA spousal-consent rules differ from IRA rules.
• Missing the heir’s annual RMD starting in 2025 — a penalty of up to 25% of the missed amount applies.
• Taking the whole estate-bound IRA in one tax year — bunched income can jump you two brackets.
• Letting the probate estate close too early — closing before the 5-year payout ends removes the option to spread distributions.

Do’s and Don’ts

Do’s

• Do name both a primary and a contingent beneficiary, because the contingent catches the asset if the primary dies first.
• Do review every IRA form after a marriage, divorce, birth, or death, because life events break old designations.
• Do keep a signed copy of each form, because custodians lose paperwork and the copy proves your intent.
• Do consider a properly drafted trust as beneficiary for minor or special-needs heirs, because it controls how young heirs receive the money.
• Do confirm in writing that the custodian recorded your update, because an unprocessed form is the same as no form.

Don’ts

• Don’t use the will to direct IRA assets, because the form controls and the will is ignored.
• Don’t assume state law will revoke an ex-spouse, because many states have no such rule.
• Don’t name your estate unless an attorney advises it, because it forfeits the longest payout.
• Don’t wait until the final year to empty an estate-bound IRA, because the tax compression is brutal.
• Don’t guess your RBD or RMD factor, because a wrong number triggers IRS penalties.

Pros and Cons of Letting an IRA Pass Through the Estate

Pros

• It still reaches your heirs, because the will then governs distribution — useful when no form exists.
• It consolidates assets under one document, because everything flows through the estate the will controls.
• It can fund estate debts and expenses, because estate cash can cover what is owed before heirs are paid.

Cons

• It loses the 10-year stretch, because an estate is a non-designated beneficiary.
• It forces faster, higher taxes, because the 5-year or ghost schedule compresses income.
• It exposes the IRA to creditors and probate, because probate assets are reachable and public.
• It delays the heirs’ access, because probate can take many months to a year or more.
• It removes the spousal rollover option, because a spouse cannot roll an IRA inherited through the estate.

What to Do Next

Take these steps in order:

1. Request your current IRA beneficiary form from each custodian and read exactly who is listed today.
2. Update any form that no longer matches your wishes, naming both primary and contingent beneficiaries, and get written confirmation it was recorded.
3. If you divorced or remarried, re-sign every form now rather than relying on state revocation rules.
4. If you are an heir, ask the custodian whether a valid form names a person or whether the IRA goes to the estate.
5. If the IRA is estate-bound, gather the date of death, the owner’s age, and the RBD to determine whether the 5-year or ghost-life-expectancy rule applies.
6. Calculate any required heir RMD for 2025 and later, and take it by December 31 to avoid the penalty, filing Form 5329 to request relief if you missed one.
7. Call a CPA or estate attorney when a trust, a special-needs heir, a sizable account, or a will-versus-form conflict is involved — this is exactly the complex situation that warrants paid help.

FAQs

Does a will override an IRA beneficiary form? No. In nearly every state the signed beneficiary form controls the IRA and overrides the will. The will only directs the IRA when no valid form names a living person.

Can I name my estate as my IRA beneficiary on purpose? Yes, but it usually backfires. The estate is a non-designated beneficiary, so heirs lose the 10-year rule and must use the faster 5-year or ghost-life-expectancy schedule, raising taxes.

What happens to an IRA with no beneficiary named? It usually passes to your estate. Most custodial agreements default to the estate, which then distributes the IRA under your will using the 5-year or ghost-life-expectancy payout, not the 10-year stretch.

How long does an estate have to empty an inherited IRA? Five years if the owner died before their required beginning date. If the owner died on or after it, the estate uses the owner’s remaining single-life “ghost” expectancy instead.

What is the required beginning date for RMDs in 2025? Generally age 73 under current law, with the first RMD due by April 1 of the year after the owner turns 73. The owner’s age at death sets the estate’s payout rule.

Does divorce automatically remove my ex from my IRA form? Only in some states. Many Uniform Probate Code states revoke a former spouse’s designation automatically, but states without that statute leave the ex on the form and let them inherit.

Can an heir spread the tax on an estate-bound IRA? Yes, within the deadline. Under the 5-year rule, heirs can take distributions across all five tax years instead of one, which lowers the marginal tax rate on the money.

Do beneficiaries pay a penalty for missing an inherited IRA RMD? Yes — up to 25% of the amount they should have withdrawn. The penalty can drop to 10% if corrected within two years by filing Form 5329, and the IRS may waive it.

Is a Roth IRA treated the same as a traditional IRA here? Mostly yes for who inherits and the payout deadlines. The 10-year and estate rules still apply, but qualified Roth withdrawals are tax-free, so the tax bomb risk is far smaller.

Should I use a trust instead of naming a person on the form? Sometimes. A properly drafted see-through trust helps with minor, spendthrift, or special-needs heirs, but a poorly drafted one can trigger the 5-year rule, so use an estate attorney.

Can the executor change who inherits the IRA after death? No. Once the owner dies, the beneficiary designation is locked. The executor must pay whoever the valid form names and cannot redirect the account to a different person.

Does my workplace 401(k) follow the same will-versus-form rule? Yes for the form winning, but 401(k)s add ERISA spousal-consent rules that often require your spouse to be the beneficiary unless they sign a waiver, which IRAs do not require.
