Inherited Roth IRA Rules for Surviving Spouses: Your Tax-Free Advantage

This guide covers Roth IRA and Roth 401(k) inheritance rules for surviving spouses under 2026 law. Not tax or legal advice — your specific situation matters.

Your three options at a glance

Option 1: Spousal rollover — make it your own Roth IRA

You contact the custodian (Fidelity, Vanguard, Schwab, etc.), provide a death certificate, and move the inherited Roth IRA into a Roth IRA in your own name. From that point it is your Roth IRA — not a beneficiary account. This unlocks the most powerful feature of a Roth IRA: you will never be required to take a distribution.¹

What changes when you do the spousal rollover:

• No RMDs — ever. Roth IRA owners have no lifetime required minimum distribution obligation. The account can grow tax-free indefinitely.
• You can contribute to the account again if you have earned income (within the 2026 income limits of $153,000–$168,000 MAGI for single filers).²
• The 5-year clock: qualified distributions of earnings require the Roth to be at least 5 years old — but you inherit your spouse's original 5-year period. If your spouse opened their Roth IRA in 2018, the clock started then. You don't restart from zero. (See the 5-year rule section below.)
• You are subject to the 10% early withdrawal penalty on earnings if you're under 59½ — which is why keeping it as an inherited Roth (Option 2) is often smarter for younger surviving spouses.

Option 2: Keep it as an inherited Roth IRA

If you need penalty-free access to the funds before age 59½, keeping the Roth as an inherited account is often better. Inherited Roth IRA distributions are never subject to the 10% early withdrawal penalty, regardless of your age.¹

The RMD rules for inherited Roth IRAs held by surviving spouses are favorable:

• You are not required to take distributions immediately. You can elect to treat the RMD rules as if your spouse were still alive — meaning RMDs are effectively delayed until the year your spouse would have turned 73 (or 75 if born in 1960 or later under SECURE 2.0).
• When RMDs do begin, they are calculated using your own life expectancy under the Single Life Table — the same stretch schedule available before SECURE Act. (The 10-year rule that applies to most non-spouse beneficiaries does NOT apply to surviving spouses.)
• All distributions are tax-free if the original 5-year requirement is met.

The inherited-Roth path makes the most sense when you are under 59½ and need income, or when you are within a few years of 59½ and want the flexibility to access funds without penalty before rolling over.

The 5-year rule: does your inherited Roth qualify for tax-free distributions?

For Roth IRA distributions to be "qualified" — meaning earnings come out completely tax-free — two conditions must be met:¹

1. You are age 59½ or older (or the distribution is for a qualifying reason).
2. The Roth IRA has been open for at least 5 tax years since the first contribution was made.

When you inherit your spouse's Roth IRA, you inherit their 5-year clock. You do not start over. The clock started the year your spouse made their first Roth IRA contribution (or conversion).

The interaction with your own existing Roth IRA: If you have had your own Roth IRA since before 2022, your 5-year clock is already satisfied. When you roll the inherited Roth into your existing account, the older clock governs. You only face a 5-year issue if neither you nor your spouse had a Roth IRA until recently.

Roth IRA contributions (not earnings) can always be withdrawn tax-free and penalty-free regardless of the 5-year rule or your age. Only the growth is subject to the seasoning requirement.

Inheriting a Roth 401(k) or Roth 403(b) from your spouse

Starting in 2024, SECURE Act 2.0 §325 eliminated required minimum distributions from Roth 401(k) accounts during the account owner's lifetime.³ If your spouse was still working and had a Roth 401(k) or Roth 403(b), you have two primary choices:

1. Roll to your own Roth IRA — the most common and usually best path. The money leaves the employer plan entirely, becomes your Roth IRA, and inherits the strongest protection: no RMDs, continued tax-free growth, flexible access to contributions. The 5-year rule for earnings applies based on the oldest Roth clock you own (either the plan's or your own IRA's, whichever is earlier).
2. Leave in the employer plan temporarily — allowed at most plans for a period; useful if the plan has exceptional investment options or low fees. You will need to roll out eventually, and leaving the account in a deceased person's name creates administrative complexity.

The rollover from a Roth 401(k) to a Roth IRA is a direct trustee-to-trustee transfer. There is no income tax on the transfer, no 20% withholding trap (unlike traditional 401(k) to traditional IRA rollovers made with a check), and no limit on the amount.

The tax-free income planning advantage for widows

For surviving spouses who face the widow's tax penalty — permanently higher single-filer brackets — a well-managed Roth IRA is one of the most powerful tools available. Here's why:

• Roth distributions don't count toward provisional income. Social Security benefit taxation is calculated on provisional income (AGI + tax-exempt interest + half of SS). Roth withdrawals are not included in this formula. A widow with $80,000 in traditional IRA RMDs and $30,000 in Social Security could be taxing 85% of SS. Replacing $20,000 of the RMD with Roth withdrawals reduces the taxable SS with no other change.
• Roth distributions don't count toward IRMAA. Medicare Part B and Part D surcharges (IRMAA) use MAGI from 2 years prior. Roth withdrawals are not included in MAGI. A widow drawing $20,000 from a Roth instead of a traditional IRA could avoid the first IRMAA surcharge tier — saving $972/year on Part B premiums alone at the 2026 single-filer $109,000 threshold.⁴
• Zero tax on qualified withdrawals. No federal income tax, no net investment income tax (NIIT), no state income tax in most states.

Should you convert more to Roth now?

Inheriting a Roth IRA often prompts a broader question: should you convert some of your own traditional IRA or inherited traditional IRA assets to Roth while you're in a lower bracket? For many widows, the answer is yes — especially during the joint-return year (the last year you can file MFJ) and the two years of Qualifying Surviving Spouse status.

Those years offer MFJ bracket thresholds roughly double the single-filer equivalent. Filling up the 22% MFJ bracket ($211,400 in 2026) can convert tens of thousands of traditional IRA dollars at a rate lower than the 22–24% you'll pay as a single filer later. See the Roth conversion strategy guide for widows for a full walkthrough.

Step-by-step: how to roll an inherited Roth IRA into your own account

1. Contact the custodian immediately. Fidelity, Vanguard, Schwab, and most major custodians have a survivor services team. Tell them you are the surviving spouse and want to do a spousal rollover to your own Roth IRA. They will send a death-claim packet.
2. Provide documentation: certified death certificate, your own ID, the account number, and (at most custodians) a completed beneficiary claim form.
3. Choose the receiving account. You can roll to an existing Roth IRA at the same custodian or open a new one. A direct trustee-to-trustee transfer is safest — no 60-day window, no withholding risk.
4. Verify the 5-year tracking. Ask the custodian to note the original Roth IRA's establishment date in the account records. Custodians track this, but it can get lost in rollovers. You want documentation if you ever need to prove qualified-distribution status to the IRS.
5. Update your own beneficiary designations. Now that this is your account, make sure it has named beneficiaries. Don't let it pass through probate. See the beneficiary update guide for a full checklist.

Common mistakes surviving spouses make with inherited Roth IRAs

• Cashing it out. A lump-sum distribution of an inherited Roth IRA is not taxable if the 5-year rule is met — but you permanently lose the tax-free growth and the estate-planning advantage. Most people regret this decision within a few years.
• Not rolling over because "Roth doesn't have RMDs anyway." True for you as owner — not true if you keep it as an inherited account. Inherited Roth IRAs eventually require distributions (life expectancy stretch). Roll to your own account to eliminate RMDs permanently.
• Assuming you can contribute to the inherited Roth IRA. You cannot contribute to an inherited IRA. If you want to contribute to a Roth, you must do so to your own Roth IRA (with earned income and within income limits).
• Missing the 5-year documentation. If your spouse opened their first Roth IRA via conversion (not contribution), the 5-year clock for conversions is separate from the 5-year clock for contributions. Get records.
