What is personal income tax in Malaysia?
Personal income tax is the tax you pay on the income you earn each year. In Malaysia it is administered by the Inland Revenue Board, known in Malay as Lembaga Hasil Dalam Negeri (LHDN) and in English as IRBM. The tax is calculated on your income for a calendar year, and you report and pay it the following year.
Malaysia uses a progressive tax system for resident individuals: the more you earn, the higher the rate applied to each additional slice of income. This means only the portion of your income that falls within a higher band is taxed at the higher rate, not your whole income.
Most of the process now happens online through MyTax, LHDN's official portal, where you log in and complete your return using e-Filing. You do not need to visit a tax office to file.
Who must register and file?
If you have income that is taxable in Malaysia, you generally need a tax file number and may need to file an annual return. Employees usually have tax deducted from their salary each month through the Monthly Tax Deduction (Potongan Cukai Bulanan, or PCB) scheme, but that does not automatically remove the obligation to file a return.
As a rough guide, you should register for a tax file and check your filing obligation if any of the following apply to you:
- Your annual employment income exceeds the threshold at which tax becomes payable (confirm the current figure on the LHDN website, as it changes by year of assessment).
- You run a business, freelance, or are self-employed in Malaysia.
- You earn rental income from Malaysian property.
- You receive other taxable income such as certain royalties, commissions, or director's fees.
What income is taxable?
Malaysia generally taxes income that arises in or is derived from Malaysia. The main categories of taxable income for individuals include employment income, business or professional income, rental income, and certain other gains such as royalties and interest.
Employment income is broader than just your basic salary. It typically includes bonuses, allowances, commissions, and the value of certain benefits and perquisites your employer provides. Your employer summarises this for you each year on the EA form, which is the starting point for most employees when they file.
- Employment income: salary, bonuses, allowances, commissions, and taxable benefits.
- Business income: profits from a sole proprietorship, partnership, freelance, or professional practice.
- Rental income: rent received from letting out Malaysian property.
- Other income: certain royalties, interest, and other gains specified under the law.
Resident vs non-resident — why it matters
Your tax residency status determines which tax rates and treatments apply to you. Residency for tax purposes is based mainly on how many days you are physically present in Malaysia during the year, not your nationality or immigration status.
Resident individuals are taxed using the progressive (tiered) rates and can claim personal reliefs and rebates that reduce their tax. Non-residents are generally taxed at a flat rate on Malaysian-source income and usually cannot claim the personal reliefs available to residents. If you are unsure of your status for a given year, confirm the day-count rules on the LHDN website before you file.
The year of assessment explained
Malaysia organises tax around the year of assessment (YA), which runs from 1 January to 31 December and matches the calendar year. The income you earn during a year is assessed in that same year of assessment and reported in the return you file the following year.
For example, income earned during 2025 falls under year of assessment 2025, and you would normally declare it in the filing period in 2026. Keeping your records, receipts, and EA form organised by year of assessment makes filing far easier and reduces the risk of missing a relief you are entitled to.
From gross income to tax payable
Working out your tax is a step-by-step process. You start with your total gross income, subtract anything that is exempt or deductible, apply your personal reliefs to reach your chargeable income, calculate the tax on that amount using the relevant rates, and finally subtract any rebates and tax already paid through PCB.
Reliefs and rebates are where many taxpayers either save money or accidentally leave it on the table. Reliefs reduce the amount of income that is taxed, while rebates reduce the final tax bill directly. Common reliefs cover things like approved retirement and medical contributions, lifestyle spending, education, and family-related expenses — but the exact categories and ringgit limits change by year of assessment, so always confirm the current figures on the LHDN website.
- Start with total gross income from all taxable sources.
- Remove exempt income and allowable deductions.
- Subtract eligible personal reliefs to arrive at your chargeable income.
- Apply the relevant tax rates to your chargeable income.
- Subtract rebates and the tax already deducted (PCB) to find the balance payable or refundable.
Where reliefs, rebates, and tools fit in
Because reliefs and rebates depend on receipts and limits that reset each year, good record-keeping throughout the year is the single biggest factor in paying the right amount of tax. Saving receipts as you go — rather than scrambling in March — means you can claim everything you are entitled to with confidence.
This is exactly the gap CukaiBro is built to close: it tracks the reliefs you qualify for, stores your receipts in one place, and computes your estimated tax payable in real time so there are no surprises at filing.
