How to prepare for a payroll audit

Treat every month as if someone will sample it — not only year-end. Auditors (internal, statutory, customer, or tax) look for completeness, accuracy, and whether statutory remittances match registers.

Audit pack essentials

• Employee master and contracts for the sample period
• Payslips, payroll registers, and bank payment proofs
• Statutory contribution calculations and remittance receipts
• OT/approval logs and variable pay evidence
• Journal entries tying payroll to the GL
• Change logs for bank details and salary adjustments

Month-end habits that make audits easy

1. Lock the cycle after sign-off; no silent spreadsheet edits.
2. Store remittance confirmations in the same folder as that month’s register.
3. Reconcile headcount and gross pay to HRIS and GL.
4. Document exceptions (off-cycles, backpay) with approvals.
5. Review access rights for payroll systems quarterly.

Privacy and security matter in audits too — see data privacy and security best practices.

Multi-country Asia tip

Create a standard pack template per country (Singapore CPF, Malaysia EPF/SOCSO/PCB, Indonesia BPJS, etc.) so regional finance can request samples without reinventing the list each time.

Two-week audit sprint plan

1. Days 1–2: pull sample employee list and request contracts
2. Days 3–5: match payslips → registers → bank proofs → remittances
3. Days 6–8: investigate exceptions and missing approvals
4. Days 9–10: fix access rights and archive gaps
5. Days 11–14: write remediation owners and due dates

FAQ

How far back should we keep payroll records?

Follow the longest of company policy, local law, and customer contract — often several years. Confirm with counsel.

What do auditors sample first?

Often high earners, joiners/leavers, OT-heavy roles, and months with corrections.

Can a payroll partner help?

Yes — outsourcing providers should supply registers, remittance proofs, and audit support as part of delivery. See payroll outsourcing.
