How Long Should You Keep Form 5472 Supporting Records?

November 13, 2026 · 2 min read

For records subject to 26 CFR 1.6038A-3, retention continues while they may be relevant or material to the tax treatment of a related-party transaction. The regulation sets the applicable assessment and collection limitations periods as a minimum. The IRS general recordkeeping page gives different time periods for different circumstances, so a single blanket deletion date is a poor fit.

What to check

Use the tax year to organize your archive, then map each transaction to the ledger, payment record and agreement that supports it. The Form 5472 instructions point to the record-maintenance requirements and explain that failure to maintain records can carry penalties. A closed bank account or a change of accounting software can make later retrieval difficult. Keep an accessible copy of documents rather than relying on an old login or a total copied into a spreadsheet.

Example

A founder contributed equipment and later disposed of it. An older transfer agreement and valuation record may help explain a later year's figures. Keep the connection between the older record and the later event in the archive. Ask a qualified tax professional to review the retention period before disposing of material records.

Before you proceed

Keep the as-filed package and the documents that substantiate the related-party entries.
Link records that remain relevant across tax years.
Review open IRS notices and applicable limitations periods before setting a deletion date.

Is keeping the submitted Form 5472 PDF enough?

The form records the report. Keep the underlying records needed to explain the transactions and support the reported amounts.
