Roughly 1.2 million surviving spouses inherit a retirement account in the United States each year. The Government Accountability Office reports that documentation gaps in the first 18 months are the most common trigger for IRS correspondence on inherited IRA accounts.

The election the surviving spouse makes (spousal rollover, treat-as-own, or Inherited IRA) is governed by IRS Publication 590-B, Chapter 1 (What if You Inherit an IRA?) and IRC §408(d)(3)(C).

Once the election is in place, the audit trail is what matters. The IRS can question the rollover characterization, the basis carry-over, and the RMD treatment for as long as the relevant statute of limitations remains open.

A surviving spouse who keeps the wrong subset of documents can find a tax-free transfer reclassified as a taxable distribution years later, with interest. If you are still researching which dealer to trust with the rolled-over balance, our 2026 reality check on gold IRA dealers names the operators we rule out for cold-calling surviving spouses.

This guide lists every document a surviving spouse should retain. It covers the retention period set by IRS rules or the statute of limitations on assessment. It identifies the source of each retention rule and walks through the practical workflow for assembling the file in the first 18 months after the death event.

The rules apply equally to a Traditional IRA, a SEP-IRA, a SIMPLE IRA, and a rolled-over 401(k), 403(b), TSP, or 457(b) balance. The fact pattern assumed here is a sole-beneficiary surviving spouse; multi-beneficiary fact patterns add separate-account paperwork that is briefly noted at the end.

What the IRS expects you to keep, and for how long

The IRS does not publish a single “inherited IRA recordkeeping” checklist. The retention periods come from three statutory and regulatory sources, layered together. The general statute of limitations on assessment is three years from the date the return was filed, under IRC §6501(a).

If the IRS asserts a substantial understatement of gross income (more than 25%), the statute extends to six years under IRC §6501(e). If the IRS asserts fraud or non-filing, there is no statute of limitations.

The recordkeeping guidance in IRS Publication 17, Chapter 1 (Filing Status and Recordkeeping) reflects this layered framework and recommends seven years as a safe practice for most filers. Inherited IRA paperwork has two additional retention drivers on top of the statute of limitations: basis tracking under Form 8606 and the indefinite need to prove the original election decision.

The chart below summarizes the retention period for each document class an inherited-IRA surviving spouse should keep. The chart is built from the IRS publications cited above and the form instructions linked in the Sources cited section at the foot of this page.

Precious metals IRA early-withdrawal penalty estimator

Taking money out of a precious metals IRA before age 59 and a half triggers a 10% federal additional tax on top of ordinary income tax. State add-on taxes vary; check your state. The federal penalty is estimated below.

Amount withdrawn (USD) Your age Combined marginal income tax rate (optional %)

Estimate only, not tax advice. The 10% federal additional tax applies to early distributions before age 59 and a half; specific exceptions exist. Your state may add its own tax, and ordinary income tax applies separately. Source: IRS Publication 590-B. Consult a tax advisor.

Documents from the death event itself

The death event produces a set of vital records that the IRA custodian, the plan administrator, and the IRS may each request at different points over the lifetime of the inherited account. Order more copies than seem necessary; the marginal cost of an extra certified death certificate is modest, and reordering later is administratively painful.

Certified death certificate, four to six copies. The IRA custodian, the prior 401(k) plan administrator, the Social Security Administration, the surviving spouse’s estate attorney, and the title agent for any joint property each typically require a certified original (not a photocopy). The Social Security Administration needs one to process survivor benefits. Retain at least two unused certified originals indefinitely.
Marriage certificate, certified copy. The custodian requires this to verify spousal status for the IRC §408(d)(3)(C) rollover election or the Treas Reg §1.408-8 Q&A-5 treat-as-own election. Order a certified copy from the vital-records office of the state where the marriage took place, not a photocopy of the original certificate.
Original beneficiary designation form. The custodian’s copy of the form on file at the date of death is the controlling document. If a more recent designation exists but was never executed by the custodian, the older valid form controls. Request a copy of the form on file in writing and retain it indefinitely.
The deceased’s last federal tax return. Form 8606 from the deceased’s prior years is the source of any non-deductible basis that carries over to the surviving spouse. Without the basis history, the IRS treats all distributions as fully taxable.
Surviving spouse’s photo identification. Driver’s license or passport. Custodians require this to retitle the account.
Letters Testamentary or Small Estate Affidavit. Required only if the IRA passes through probate (which is rare for accounts with a named beneficiary). If the IRA was payable to the deceased’s estate by default, the executor needs court authority to direct the rollover.

Documents from the rollover or election decision

The election the surviving spouse makes (spousal rollover, treat-as-own, or Inherited IRA) is the single highest-value document in the inherited file. The IRS can question the characterization for as long as the related tax year remains open under IRC §6501. If the supporting paperwork has been discarded, the surviving spouse loses the ability to prove a non-taxable rollover and the IRS default treatment is taxable distribution.

Custodian’s election form, signed and dated. The form should state the election explicitly (spousal rollover, treat-as-own, or beneficiary IRA), the source account, the destination account, and the dollar amount. Retain the executed original indefinitely. A scanned copy in cloud storage is not a substitute; the IRS occasionally requests an ink-signed copy on audit.
Written confirmation from the custodian that the election was processed. This is typically a one-page acknowledgment letter with the new account title (e.g. “Jane Doe IRA” for a spousal rollover or “John Doe IRA, deceased, FBO Jane Doe, beneficiary” for an Inherited IRA). Retain indefinitely.
Trustee-to-trustee transfer authorization, if applicable. For a rollover from a 401(k) or other employer plan to an IRA, the direct transfer form should specify code G coding for the 1099-R. Retain indefinitely; this is the paperwork that proves the rollover qualified for non-taxable treatment.
Summary Plan Description (SPD) from the deceased’s prior employer. Required only when the source account is a 401(k), 403(b), or 457(b). The SPD documents the survivor benefit rules under ERISA §205 and the plan’s specific election procedures. The plan administrator is required to furnish a copy on written request.
Account statement from the source plan as of the date of death. This is the valuation document for the rollover. It establishes the rolled-over balance for basis tracking and for any later step-up question. Retain indefinitely.
RMD calculation worksheet for the year of death. If the deceased was past the required beginning date (currently age 73, rising to 75 in 2033 under SECURE Act 2.0), the surviving spouse must take the deceased’s unfinished RMD for the year of death before the rollover. The worksheet proves that the RMD was satisfied.

Form 1099-R and Form 5498: the annual reporting trail

Once the election is in place, the inherited account generates two IRS forms each tax year. Both should be retained for at least seven years from the date the related Form 1040 was filed, per the layered statute of limitations under IRC §6501.

Form 1099-R reports distributions from a retirement account. For the rollover year itself, the surviving spouse should receive a 1099-R from the source custodian. The code in Box 7 will be G (direct rollover) if a trustee-to-trustee transfer was used, or code 4 (death) for an Inherited IRA distribution.

Code G means the gross amount in Box 1 is reported but the taxable amount in Box 2a is zero. If the form arrives with the wrong code, the surviving spouse has until the end of the calendar quarter to request a corrected 1099-R from the custodian. Form 1099-R instructions describe the full code list.

Retain every 1099-R received over the life of the inherited account for seven years from the related filing date.

Form 5498 reports contributions, rollovers, conversions, and the year-end fair market value of the IRA. The custodian issues Form 5498 every year the account is open, even if there was no contribution.

Box 2 reports rollover contributions, Box 5 reports the year-end fair market value, and Box 11 indicates whether an RMD is required for the following year. Form 5498 instructions note that the form is issued by May 31 of the year following the tax year. Surviving spouses should not file the prior year’s Form 1040 expecting to use a current Form 5498 number.

Retain every 5498 indefinitely while the account is open; this is the audit trail for the full rollover history.

Form 5329 and Form 8606: basis tracking and penalty exceptions

Two forms govern the long-tail tax treatment of an inherited IRA: Form 8606 (non-deductible contribution basis tracking) and Form 5329 (additional taxes on qualified plans, including the missed-RMD excise tax and early-withdrawal exceptions).

Form 8606 tracks the cost basis from non-deductible Traditional IRA contributions. If the deceased made non-deductible contributions during their lifetime, the basis carries over to the surviving spouse on a spousal rollover and reduces the taxable portion of every future distribution.

Without an unbroken chain of Form 8606 filings, the IRS treats every dollar distributed as fully taxable. Form 8606 instructions require the form to be filed for every year a non-deductible contribution was made or a distribution was taken from an account holding basis.

Retain Form 8606 indefinitely, alongside the originating contribution receipts; the basis figure is the cumulative running total since the first non-deductible contribution, possibly going back decades.

Form 5329 reports additional taxes on qualified plans. For an inherited IRA, two uses matter. The first is the 25% excise tax under IRC §4974 for any RMD shortfall (reduced from 50% by SECURE Act 2.0, with further reduction to 10% if corrected within the correction window). The second is documenting an early-withdrawal penalty exception under IRC §72(t).

For a surviving spouse who keeps the account as an Inherited IRA, distributions are never subject to the IRC §72(t) 10% early-withdrawal additional tax regardless of age, and Form 5329 documents that.

For a surviving spouse who elected the spousal rollover and later takes a pre-59½ distribution, Form 5329 documents any applicable exception (substantially equal periodic payments, medical expenses, first-home purchase, etc.). Form 5329 instructions include the full exception code list.

The first 18 months: a workflow for assembling the file

The retention list above is dense. In practice, surviving spouses assemble the inherited-IRA file in three stages, paced over the 18 months following the death event. Stage 1 (weeks 0 to 8) is documentation of the death event itself. Stage 2 (months 2 to 6) is the election decision and the rollover paperwork.

Stage 3 covers months 6 to 18: the first tax filing and the first full set of 1099-R and 5498 forms. Surviving spouses who delay Stage 2 past the year-end of the year following the death may find the IRS treats their inaction as a deemed treat-as-own election under Treas Reg §1.408-8 Q&A-5.

Six-step procedural flowchart of the 18-month workflow a surviving spouse follows to assemble the inherited IRA paperwork file: weeks 0 to 8 order certified death certificates and request the original beneficiary designation form, months 2 to 4 choose the IRS election (spousal rollover, treat-as-own, or Inherited IRA), months 2 to 6 execute the custodian election paperwork and retain ink-signed originals, May 31 of year 1 file the first Form 5498 from the custodian, January of year 2 receive the first Form 1099-R for any distributions, April 15 of year 2 file the first Form 1040 with Form 8606 for basis carry-over. — Figure 2. Canonical 18-month workflow for assembling the inherited IRA documentation file. Each step produces a paper deliverable retained in the surviving spouse's binder. Sources: IRS Publication 590-B Chapter 1, Treas Reg §1.408-8 Q&A-5, Form 5498 instructions.

Inside that workflow, the practical filing convention used by most estate attorneys is a single labeled binder (or its digital equivalent) divided into seven tabs: 1. Vital records, 2. Election decision, 3. Source-plan documentation, 4. Annual 1099-R, 5. Annual 5498, 6. Form 8606 basis history, 7. RMD worksheets. The binder lives with the surviving spouse’s tax records, not with the will or trust documents. Two copies are common practice: one with the surviving spouse, one with the executor or CPA.

Common mistakes surviving spouses make in the first 18 months

The IRS does not publish an audit-trigger list specific to inherited IRAs, but the consistent patterns from estate-attorney post-mortems and from Government Accountability Office reporting (GAO-19-179) point to five recurring documentation failures. Each one converts an avoidable administrative task into a costly tax exposure.

Discarding the original Form 8606 chain. A surviving spouse who consolidates the inherited balance with their own existing IRA without retaining the deceased’s prior-year Form 8606 filings loses the non-deductible basis. Every dollar later distributed is then treated as fully taxable, even though some portion already had tax paid on it. The fix is to request all prior-year Form 8606 filings from the IRS using Form 4506-T (transcript request) before discarding any of the deceased’s tax records.
Accepting a 1099-R with the wrong code in Box 7. A direct trustee-to-trustee transfer must be coded G. If the form arrives coded 1 (early distribution, no known exception) or 7 (normal distribution), the surviving spouse has a narrow window to request a corrected form before the IRS uses the wrong code to assert tax. Corrected 1099-R forms (1099-R with “CORRECTED” checked) must be retained alongside the original.
Failing to take the year-of-death RMD. If the deceased was past their required beginning date and had not taken the full RMD for the year of death, the surviving spouse must complete the deceased’s RMD before any rollover. Skipping it produces an excess-contribution problem in the destination IRA and a 25% missed-RMD excise tax under IRC §4974.
Letting the election decision drift past December 31 of the year after death. Under Treas Reg §1.408-8 Q&A-5, inaction past that deadline is treated as a deemed treat-as-own election. A surviving spouse who intended to keep the account as an Inherited IRA loses that status and the IRC §72(t) penalty exemption reactivates. The fix is to put the intended election in writing to the custodian before the deadline.
Not retaining the source-plan SPD. If the rollover is from a 401(k), 403(b), or 457(b) and the plan later corrects an administrative error, the SPD is the document that proves the surviving spouse’s right to the survivor benefit under ERISA §205. Plan administrators are required to furnish a copy on written request; the request itself should be retained alongside the SPD.

How does the IRS audit an inherited-IRA election?

The IRS does not run a dedicated inherited-IRA audit program. The election characterization is examined in the same correspondence-audit channel that handles other Form 1099-R reconciliation issues. The trigger is usually a mismatch between the 1099-R Box 1 gross amount and the Form 1040 line for taxable IRA distributions.

A correctly coded G rollover produces a Box 1 amount with a Box 2a taxable amount of zero, which the IRS reconciles against the Form 5498 rollover-contribution Box 2 entry on the destination IRA. If both forms match, the file closes.

If they do not match, the IRS sends a CP2000 notice requesting the supporting paperwork (the custodian’s election form, the rollover authorization, the SPD if applicable, and the prior-year 1099-R or 5498). Retaining the documents listed in the sections above is what allows a quick CP2000 response and avoids escalation to a field audit.

What happens if you lose Form 5498 from a prior year?

The custodian is required to keep copies of every Form 5498 it issued for at least four years under IRS recordkeeping rules. A request to the custodian’s records department for a duplicate Form 5498 is the first step. The custodian typically furnishes a duplicate within ten business days at no charge.

If the custodian has been acquired or has discarded older records, the IRS will furnish a transcript of the 5498 information reported by the custodian. File Form 4506-T (Request for Transcript of Tax Return) and select the wage and income transcript option for the relevant tax year. The wage and income transcript covers the prior ten years.

Can the custodian provide replacement statements after the account is closed?

Custodians are required to keep account records for at least seven years after the account is closed under SEC Rule 17a-4. A written request to the closed-account records department, citing the original account number and the surviving spouse’s identification, produces a duplicate statement set within 30 days at most custodians. A modest reproduction fee may apply for paper copies.

The seven-year window starts from the date the account was formally closed, not the date of the last transaction. A surviving spouse who closes the account after a final distribution has seven years from that closure date to request records.

Where does this leave a surviving spouse choosing a custodian?

The retention rules above apply to every IRA custodian. They do not change based on whether the surviving spouse rolls the balance to a conventional brokerage IRA, a precious-metals self-directed IRA, or stays with the deceased’s existing custodian.

What does change with a precious-metals self-directed IRA is the depository statement set: the surviving spouse receives additional documentation from the IRS-approved depository confirming the physical metal holdings, alongside the custodian’s account statements.

Some operators handle the documentation cleanly; others rush the paperwork on a grieving surviving spouse and create the kind of errors the previous section described. Our 2026 reality check on gold IRA dealers names the operators we currently warn against on inherited-account fact patterns and the small set whose paperwork practices have held up across multiple OPRS reviews.

Augusta Precious Metals is one of the operators that surviving spouses sometimes evaluate at this stage.

As context: BBB A+ accredited since 2014 with no complaints on file. Named Money Magazine’s Best Overall Gold IRA Company every year from 2022 through 2026, and Investopedia’s Most Transparent Gold IRA Company 2022 through 2026. Augusta holds 4,000+ 5-star ratings across Trustpilot, Google, and Consumer Affairs. Augusta’s published process is Education-First: Learn, Talk, Decide, with salaried, non-commissioned educators.

The industry-reported minimum sits around $50,000 for gold IRA accounts. Whether Augusta is a fit depends on the surviving spouse’s specific situation and the alternatives covered in the dealer shortlist.
