Tax compliance in Malaysia is becoming increasingly digital. One development businesses should pay attention to is the Malaysian Income Tax Reporting System, better known as MITRS.
MITRS is an online platform introduced by the Inland Revenue Board of Malaysia (HASiL) for taxpayers to submit specified tax information and supporting documents electronically.
For companies, this means that filing the income tax return may no longer be the final step in the annual tax compliance process.
What is MITRS?
MITRS stands for Malaysian Income Tax Reporting System.
Under Section 82B of the Income Tax Act 1967, taxpayers filing tax returns under the relevant provisions are required to submit information and specified documents electronically for the purpose of determining chargeable income and tax payable.
Implementation is being carried out in phases, beginning with companies and Limited Liability Partnerships (LLPs) from the Year of Assessment 2025.
What documents need to be submitted?
Depending on the taxpayer and circumstances, documents specified by HASiL include:
- audited or unaudited financial statements;
- income tax computations;
- complete capital allowance and Schedule 3 computations, where applicable; and
- complete computations for tax incentives claimed, where applicable.
The documents are submitted electronically through MITRS.
When is the MITRS submission due?
One important point businesses should be aware of is that MITRS has its own submission requirement.
Under Section 82B, the specified information and documents are generally required to be submitted electronically within 30 days after the due date for submission of the relevant tax return.
Businesses should therefore include MITRS as part of their annual tax compliance timetable rather than treating the filing of the tax return as the end of the process.
Why does this matter?
MITRS increases the importance of maintaining complete and consistent accounting and tax records.
The financial statements, tax computation, capital allowance schedules and information reported in the tax return should agree with one another.
Differences or unsupported figures may result in questions being raised during a tax review or audit.
Businesses should therefore avoid leaving their accounting and tax documentation until the last minute.
What should companies do now?
Companies should ensure that their accounting records are properly maintained and that supporting documents for significant transactions are readily available.
It is also advisable to review tax-sensitive areas such as fixed assets, capital allowances, related-party transactions, expenses with possible private elements, provisions and tax incentives before finalising the annual tax computation.
The move towards MITRS is another indication that tax compliance in Malaysia is becoming increasingly data-driven.
Good record keeping is no longer simply an accounting matter — it is an important part of managing tax risk.
