EA tax-practice recordkeeping: which retention clock applies?

Due-diligence retention uses the latest applicable date

The IRS rule considers the return due date, the date an electronically filed return was filed, the date a paper return was presented for signature, and the date a nonsigning preparer submitted their portion to the signing preparer, as applicable. Keep the required checklist, computations, information source and inquiry records; do not substitute a three-year rule measured from an arbitrary date.

Return of records is a separate duty

Section 10.28 generally requires prompt return of client records needed for federal tax compliance. It defines what counts as client records and contains qualifications involving state law and certain unpaid practitioner work. Analyze those facts instead of treating all workpapers, originals and completed deliverables as identical.

Classify the document before assigning a retention date

A tax practice holds several kinds of records: client-provided documents, completed returns, e-file signature authorizations, conflict consents, due-diligence evidence and internal work supporting advice. These categories do not all share the same retention rule. A phrase such as "keep tax records for three years" is too imprecise to answer a practitioner-recordkeeping question without knowing which document and starting event are involved.

Build a register with the document category, governing requirement, trigger date and earliest permitted disposal date under that rule. Then consider any other applicable requirement or reason the records must remain available. The minimum period for a particular federal practice rule is not permission to destroy material needed for an unresolved matter. Keep the analysis tied to the stated facts rather than inventing one universal retention policy.

Calculate from the event that the rule actually names

Conflict consents use the end of the affected representation as their minimum 36-month retention trigger. E-file Forms 8878 and 8879 use three years from the return due date or IRS received date, whichever is later. Due-diligence records use three years from the latest applicable date specified in the regulation. The periods may look similar, but a different trigger produces a different result.

For example, assume a covered e-file authorization relates to a return due April 15, 2026, received by the IRS on May 20, 2026. Using those stipulated dates, the later trigger is May 20 and the three-year period reaches May 20, 2029. That calculation says nothing about whether the return itself was timely. A retention question and a filing-deadline question can use the same dates but ask entirely different things.

Distinguish returning records from keeping copies

Section 10.28 generally requires prompt return of client records necessary for compliance with federal tax obligations. The practitioner may retain copies. The regulation defines client records and qualifies the duty for certain fee disputes, state-law situations and practitioner-created documents. Do not treat an original client bank statement, a copy already supplied to the client and an unpaid newly prepared deliverable as necessarily identical.

If a question expressly states that no applicable exception permits withholding needed records, the fee dispute is not a reason to refuse their return. If an exception is potentially relevant, analyze its conditions and any remaining access obligation. Returning what the client needs and retaining the practice’s required evidence can both be possible. A blanket refusal or destruction of the file skips those distinctions.

Keep a usable record, not just a collection of scans

A retained file should allow the relevant work to be reconstructed. Link authorizations to the return version, consents to the engagement and due-diligence notes to the eligibility question they resolved. A folder of unlabelled attachments may contain the documents but make it difficult to establish when a client consented or why a preparer accepted an inconsistent fact. Use clear dates and descriptions while protecting confidential information.

When closing an engagement, record its actual end date and outstanding obligations. If the representation remains open for another issue, do not assume the conflict-consent clock started when the original return was filed. For an exam answer, state the document, rule, trigger and resulting period in that order. That method exposes an incorrect starting date before a correct-looking arithmetic calculation hides it.
