Income tax

Scope of taxation

Income tax in Malaysia is imposed on income accruing in or derived from Malaysia. For residents, tax is also imposed on income derived from outside Malaysia and received in Malaysia. However, resident companies carrying on the business of banking, insurance, sea or air transport (BISA) are assessable on income from wherever derived (world income scope).

Subject to conditions, the following foreign-sourced income received in Malaysia by residents (other than resident companies carrying on the business of BISA) qualify for tax exemption:

Dividend income received by resident companies, limited liability partnerships (LLP), and individuals (in respect of dividend income received through a partnership business in Malaysia) from 1 January 2022 to 31 December 2026 (Budget 2026 proposed extension to 31 December 2030)
Foreign-sourced income received by unit trusts from 1 January 2024 to 31 December 2026 (Budget 2026 proposed extension to 31 December 2030)
All classes of income received by resident individuals (excluding income from a partnership business in Malaysia, which is received in Malaysia from outside Malaysia) from 1 January 2022 to 31 December 2036

Income attributable to a Labuan business activity of a Labuan entity, including the branch or subsidiary of a Malaysian bank in Labuan, is subject to tax under the Labuan Business Activity Tax Act 1990. A preferential tax rate of 3% will apply to the Labuan entity on its net profits from Labuan business activities if it meets the substantial activity requirements, otherwise it will be subject to a tax rate of 24% on its net profits. A Labuan entity can make an irrevocable election to be taxed under the Income Tax Act 1967 (ITA 1967) in respect of its Labuan business activity.

Classes of income

Income tax is chargeable on the following classes of income:

a) Gains or profits from a business

b) Gains or profits from the disposal of capital asset (refer to Taxes on Capital Gains)

c) Gains or profits from an employment

d) Dividends, interest or discounts

e) Rents, royalties or premium

f) Pensions, annuities or other periodical payments not falling under any of the foregoing classes

g) Gains or profits not falling under any of the foregoing classes

Basis of assessment

Income is assessed on a current year basis. The year of assessment (YA) is the year coinciding with the calendar year, for example, the YA 2026 is the year ending 31 December 2026. The basis period for a company, co-operative or trust body is normally the financial year (FY) ending in that particular YA. For example, the basis period for the YA 2026 for a company which closes its accounts on 30 June 2026 is the FY ending 30 June 2026. All income of a person other than a company, LLP, co-operative society or trust body, are assessed on a calendar year basis.

Malaysia adopts a self-assessment system which means that the responsibility to determine the correct tax liability lies with the taxpayer.

Returns & assessments

Taxpayers are required to submit their income tax returns to the Inland Revenue Board (IRB) within the prescribed time frame. Refer to the “Important filing dates” section for further information.

Companies, LLPs, trust bodies and co-operative societies are required to furnish the income tax returns based on the financial statements prepared in accordance with any written law.

A tax return submitted by the prescribed due date is a deemed assessment made on the taxpayer on the date of submission.

The IRB is allowed to issue an additional assessment, if it thinks that the original assessment is not sufficient, within five years (or seven years for transfer pricing issues) from the end of that particular YA. This time frame is not applicable in situations of fraud, wilful default or negligence.

Appeals

Where a taxpayer is aggrieved by an assessment made by the IRB, he may submit an appeal. Appeals against assessments raised by the IRB can be made within 30 days after the date the notice of assessment has been served. If the taxpayer and the IRB cannot come to an agreement, the appeal may be escalated to the Special Commissioners of Income Tax within a certain period.

Taxpayers can also appeal against its own deemed assessment. However, the scope of appeal is restricted only to disagreement (but conceded in its return) with the IRB’s known stand and rules prevailing at the time when the return was submitted. Examples of such known stand and rules include:

Public rulings
Private rulings or advance rulings
Guidelines issued by the IRB
