Keep Supporting Records

Explain why tax supporting documents must be kept for several years after filing — because audits and queries can arise long after the return is submitted and accepted.

In this lesson

Keep Supporting Records is part of Preparing a Simple Tax Return. This preview shows how tax-filing connects to everyday family decisions such as earning, saving, spending choices, goals, approvals, or parent-guided money conversations inside Progress Penguin.

Think about this money choice

Femi filed his tax return two years ago but threw away all his supporting documents. His tax authority has now queried one of his deductions.

How it works

Supporting documents — receipts, invoices, bank statements, payslips — must be kept for several years after filing a tax return because tax authorities can audit or query returns years after submission. If a deduction is questioned, the taxpayer must prove it was legitimate with documentary evidence. Without the evidence, the deduction may be disallowed and additional tax plus penalties may be assessed.

Apply it to a real decision

Real-life money moment: Femi filed his tax return two years ago and claimed a 45000 in local currency equipment deduction. He threw away all receipts after filing. the tax authority has now queried the deduction and asked for evidence. Without the receipts, Femi cannot prove the equipment was purchased or that it was wholly for business use. the tax authority disallows the deduction, assesses 6750 in local currency in additional tax, and adds a penalty for unsupported claims.

Quiz preview

Keeping supporting records for a tax return means:

Keeping records until the end of the tax year they relate to

Only keeping records until the tax authority confirms your return was accepted

Only keeping the final submitted return document itself as evidence

Retaining all income evidence and expense receipts for several years after filing

the tax authority audits your return from two years ago. Most useful documents to have:

Original payslips, expense receipts, and the submitted return with confirmation number

A letter from your accountant confirming the return was filed correctly

Only the submitted return since original payslips are the employer's responsibility

Nothing — the tax authority has all data they need and does not require you to retain any records
