Quick answer: A Malaysian corporate tax audit usually starts with the filed tax return, tax computation, audited financial statements and detailed ledgers. LHDN may then request invoices, contracts, bank records, capital-allowance schedules, incentive support, payroll records and related-party documentation for the issues or years under review.
Core corporate records
| Document group | Examples |
|---|---|
| Tax filings | Form C, estimates and revisions, tax computation, payment records and correspondence |
| Financial statements | Audited accounts, directors’ report, notes and consolidation schedules where relevant |
| Accounting records | Trial balance, general ledger, journal listings and detailed income-statement accounts |
| Source documents | Invoices, receipts, contracts, purchase orders, credit notes and bank statements |
| Fixed assets | Asset register, invoices, disposal documents and capital-allowance calculations |
| Tax incentives | Approval letters, applications, conditions, qualifying-expenditure and income computations |
| Related parties | Agreements, transaction schedules, balances and transfer pricing documentation |
| Employer records | Payroll, PCB, benefits, Forms E/EA/EC and employee movement notifications |
Documents submitted through MITRS
Section 82B requires specified documents to be submitted through the Malaysian Income Tax Reporting System (MITRS) within 30 days after the return due date. For year of assessment 2026, the specified set includes financial statements, the tax computation with detailed income statement and adjustments, capital-allowance schedules and incentive computations where applicable.
This routine MITRS filing is not necessarily the complete audit file. Under sections 80 and 81, LHDN may request additional information during a review. Since 1 April 2025, supporting audit documents can also be uploaded through MITRS in permitted formats.
Prepare supporting schedules, not just raw documents
A well-organised audit file explains how each figure reaches the tax return. Useful schedules include:
- Revenue reconciliation from ledger to financial statements and return;
- Expense analysis separating deductible, non-deductible and capital items;
- Bad-debt, provision and impairment movements;
- Entertainment, motor vehicle, donation and professional-fee details;
- Withholding-tax and service-tax reviews;
- Capital-allowance additions, disposals and reconciliations;
- Losses, allowances and incentive balances brought forward; and
- Related-party transaction totals by entity and category.
How long should records be retained?
Tax and employer records should generally be retained for seven years. Electronic records should remain readable and linked to the transaction. Do not rely on a former employee’s mailbox or an accounting system that can no longer export detailed data.
Document quality checks before submission
- Match the entity name and year to the notice.
- Reconcile every schedule to the filed return and accounts.
- Use clear file names and an index.
- Explain missing, cancelled or replaced documents.
- Remove genuine duplicates without omitting relevant evidence.
- Keep a complete copy of the final submission.
For response management, read what to do after an LHDN audit notice. HTL’s tax-audit support can help assess gaps before documents are submitted.
This article provides general information. The exact documents required depend on the notice, years, transactions and issues under review.
