Income tax in Malaysia is administered by the Inland Revenue Board, known locally as LHDN, and applies to most individuals who earn income in the country. Whether you must file, the rate you pay, and your deadline all depend on your residency status and the type of income you earn. Here is how the system works.
Who needs to file income tax in Malaysia?
In general, you are required to register and file an income tax return if your annual income reaches the threshold set by LHDN. Employees, the self-employed, and business owners can all fall within the net, though the exact form and filing path differ.
Before you can file, you need an income tax number. New taxpayers register through LHDN's online channel (commonly referred to as e-Daftar) to obtain that number and set up access to the MyTax portal. Because thresholds and registration rules are updated from time to time, confirm the current requirement directly with LHDN before assuming you are exempt.
How is residency determined, and why does it matter?
Your residency status drives how you are taxed, and it is decided by physical presence, not nationality. The widely applied benchmark is whether you are present in Malaysia for 182 days or more during a calendar year; meeting that test generally makes you a tax resident for that year. There are additional qualifying rules for borderline cases, so check the current criteria with LHDN if your days are close to the line.
The distinction matters because residents and non-residents are treated differently:
- Residents are taxed on a progressive scale and may claim personal reliefs and rebates.
- Non-residents are generally taxed at a flat rate on employment income and typically cannot claim the same reliefs.
What income is taxed, and at what rates?
Malaysia uses a progressive rate structure for resident individuals: lower income is taxed at lower rates, rising in bands as income increases. Non-residents face a flat rate instead. LHDN publishes the current bands and percentages each year of assessment, and because they can change, you should read the rate for your income directly from LHDN rather than relying on a figure quoted elsewhere.
Taxable income broadly includes employment earnings, business or professional income, and certain other categories defined by law. Residents may reduce the amount assessed through personal reliefs and rebates that LHDN sets — for items such as approved contributions, dependants, and specified expenses. Keep documentation for anything you claim, since you may be asked to support it.
How to file and pay through MyTax
Filing is done electronically. LHDN has moved individual return submission onto the MyTax portal, where you complete the form that matches your income type and submit it online. The key dates each year of assessment are:
| Filing situation | Typical form | Usual deadline |
|---|---|---|
| Employment income, no business | Form BE | 30 April |
| Business or self-employed income | Form B | 30 June |
These dates recur annually but can be adjusted, so confirm the exact deadline for the current year of assessment on MyTax. Late submission or late payment can trigger a penalty on the amount owed, which is why filing on time matters even if you expect a refund. After you submit, pay any balance due through the payment channels LHDN supports, and keep your records — returns, receipts, and supporting documents — for the retention period the authority specifies.
If your situation is more involved — multiple income sources, business accounts, or cross-border earnings — a licensed tax agent in Malaysia can prepare and file on your behalf and help you stay compliant.
