New IRBM Requirement: Mandatory Submission of Tax Documents via MITRS

The Inland Revenue Board of Malaysia (IRBM) has introduced the Malaysian Income Tax Reporting System (MITRS) as part of its digitalisation initiative under Section 82B of the Income Tax Act 1967.

MITRS is an online platform that enables taxpayers to submit prescribed tax documents electronically, reducing paperwork, streamlining tax compliance, and improving the efficiency of tax administration.

Who Is Affected?

From Year of Assessment (YA) 2025, the mandatory submission requirement applies to:

• Companies

• Limited Liability Partnerships (LLPs)

IRBM may extend the requirement to other categories of taxpayers in future.

What Documents Must Be Submitted?

Eligible taxpayers are required to submit the following documents through MITRS:

• Audited Financial Statements or Unaudited Financial Statements (where applicable);

• Income Tax Computation;

• Complete Capital Allowance Schedule (including Schedule 3 claims); and

• Complete Tax Incentive Computation (where applicable).

All documents must be submitted in PDF format.

When Must the Documents Be Submitted?

The prescribed documents must be submitted within 30 days after the due date for filing the Income Tax Return Form.

The legal obligation to comply with Section 82B rests with the taxpayer, namely the company or LLP. Where a tax agent has been appointed and authorised, the tax agent may prepare and submit the prescribed documents through MITRS on the taxpayer's behalf. However, the taxpayer remains ultimately responsible for ensuring compliance.

Failure to comply with the submission requirement may constitute an offence under Section 120(1)(d) of the Income Tax Act 1967 and, upon conviction, may result in a fine of RM200 to RM20,000, imprisonment for a term not exceeding six (6) months, or both.

Tax Audit Document Submission

MITRS also serves as the online platform for taxpayers to submit additional documents requested by IRBM during a tax audit under Sections 80 and 81 of the Income Tax Act 1967.

Depending on IRBM's request, supporting documents may be uploaded in various formats, including PDF, Excel, Word, CSV, TXT, PRN, JPG and PNG.

How Should Businesses Prepare?

Businesses are encouraged to:

• Complete their financial statements and income tax computation on a timely basis.

• Maintain complete capital allowance schedules and tax incentive computations.

• Prepare supporting documents in the required electronic format.

• Review their internal tax compliance processes to ensure timely submission through MITRS.
