How to File Your Income Tax in Malaysia: A Beginner’s Guide

Filing income tax for the first time can seem complicated, especially when you are faced with terms such as TIN, MyTax, e-BE, e-B, chargeable income and tax relief.

In practice, the process is more straightforward than it first appears.

For most individual taxpayers, filing now takes place online through the MyTax portal operated by the Inland Revenue Board of Malaysia, known as HASiL or LHDN. The basic process is to make sure you have a Tax Identification Number (TIN), activate your MyTax account, gather your income and supporting information, select the appropriate tax form, claim applicable reliefs, submit the return and pay any remaining tax due.

The important part is getting the details right.

This beginner’s guide explains how income tax filing works in Malaysia and what a first-time taxpayer needs to know for the 2026 filing season, which covers the Year of Assessment 2025.

Who Needs to File Income Tax in Malaysia?

Not everyone who earns money in Malaysia will necessarily end up paying income tax, but people with taxable income have reporting responsibilities.

HASiL states that taxpayers are responsible for registering or maintaining their Tax Identification Number, reporting their annual income and paying income tax where applicable. Its guidance also identifies people with taxable income, business income and certain employment situations among those who need to register for a TIN. (Hasil)

For Malaysian citizens and permanent residents aged 18 and above, TIN registration is generally created automatically using information obtained from the National Registration Department. Other individuals may need to register through the e-Daftar service in MyTax. (Hasil)

This is particularly relevant to people starting their first job, freelancers, sole proprietors, online sellers and other individuals who have income outside a conventional monthly salary.

Having a TIN does not automatically mean that you owe tax. The actual tax payable depends on your taxable or chargeable income after the applicable deductions, reliefs and rebates.

What Is a TIN?

TIN stands for Tax Identification Number.

It is the identification number used by HASiL for Malaysian tax administration.

If you are a Malaysian citizen or permanent resident aged 18 or above, you may already have a TIN even if you have never personally applied for one. HASiL says such registrations are made automatically using National Registration Department data.

People who fall outside that automatic-registration category can apply online through e-Daftar on the MyTax portal. (Hasil)

Before filing your first return, it is therefore worth checking whether a TIN already exists under your name rather than immediately submitting another registration.

Set Up Your MyTax Account

Once your tax registration is in place, the next step is accessing MyTax, HASiL’s online tax portal.

The portal is used for electronic income tax filing and other tax-related services.

HASiL’s current instructions say that a registered taxpayer making a first login without an existing digital certificate can authenticate through either e-CP55D or e-KYC, which uses identity verification through the mobile application. (Hasil)

The process may therefore look slightly different from simply creating an account on an ordinary website.

Make sure the identification details and contact information connected to your tax account are accurate. If you have changed your address, telephone number or other relevant details, update them where required.

Know Which Income Tax Form You Need

One of the most common sources of confusion for beginners is choosing the correct form.

For an individual with employment income who does not carry on a business, the relevant return is generally Form BE, submitted electronically as e-BE.

For a resident individual who carries on a business, the relevant return is generally Form B, submitted electronically as e-B.

HASiL’s 2026 filing programme confirms these categories for the Year of Assessment 2025. (Hasil)

This distinction matters for freelancers, sole proprietors and people operating businesses alongside other sources of income.

For example, someone working as a salaried employee throughout the year with no business activity would generally look at e-BE. Someone operating a sole proprietorship or carrying on a business would generally need the business return.

If your circumstances are more complicated, such as having employment, foreign income, partnership income or other specialised sources of income, check the relevant HASiL guidance before selecting a form.

Gather Your Income Information

Before opening the e-Filing form, gather the information you will need.

For an employee, this normally includes the information contained in the employer’s EA Form, which summarises remuneration and relevant deductions for the year.

You should also consider whether you received other forms of income during the year.

Depending on your circumstances, this could include:

• Salary and wages
• Bonuses
• Commissions
• Business income
• Freelance income
• Rental income
• Other taxable sources of income

Do not assume that only your monthly salary matters.

HASiL states that individuals who are subject to tax are responsible for reporting their income. (Hasil)

For someone with multiple income streams, keeping proper records throughout the year can make the filing process much easier.

Understand Chargeable Income

A common beginner’s mistake is assuming that your annual salary is automatically the amount on which you are taxed.

Malaysia’s individual income tax system works with chargeable income.

In simple terms, you start with the relevant income, then apply allowable deductions, exemptions, reliefs and other provisions that apply to your circumstances.

The resulting chargeable income is then used to determine the tax payable under the applicable tax rates.

This is why two people earning the same gross income can potentially have different tax outcomes.

The details of individual reliefs and deductions can change from one Year of Assessment to another, so taxpayers should use the current HASiL guidance rather than relying on an old tax checklist found online.

What Are Tax Reliefs?

Tax reliefs reduce the amount of income subject to tax when you meet the relevant conditions.

For a beginner, this is one of the most important parts of filing because failing to claim a relief you are entitled to can result in a higher tax bill than necessary.

Depending on the relevant Year of Assessment and your circumstances, individual tax reliefs can cover areas such as personal expenses, education, medical expenses, lifestyle-related expenditure, insurance, contributions and dependants.

The exact conditions and limits matter.

For that reason, do not simply copy a list of tax reliefs from an old article or social media post. Check the current HASiL guidance for the particular Year of Assessment you are filing.

You should also keep the relevant receipts, statements and supporting documents even where you are not required to upload them during the initial e-Filing process.

Do You Need to Upload Your Receipts?

Filing your return does not necessarily mean attaching every receipt to the online form.

However, that does not mean you should throw the receipts away.

Taxpayers should maintain supporting records for claims made in their return in case HASiL later requires evidence.

A sensible system is to keep a digital folder containing documents such as:

• EA Form
• Insurance statements
• Education receipts
• Medical receipts
• Donation receipts where applicable
• Relevant EPF or contribution records
• Receipts supporting eligible lifestyle claims
• Business records if you are self-employed
• Other documents supporting deductions or reliefs

For business owners and freelancers, record-keeping becomes particularly important because business income and allowable expenses can require more detailed documentation.

Calculate Your Tax Payable

After entering your income and applicable reliefs, the MyTax system calculates the tax position based on the information submitted.

Malaysia uses progressive tax rates for resident individuals.

For the Year of Assessment 2025, HASiL’s published rate schedule starts at 0% for the first RM5,000 of chargeable income and increases through successive bands. The schedule reaches 30% for chargeable income exceeding RM2 million. (Hasil)

This does not mean that someone earning more than RM2 million pays 30% on every ringgit of their income. Progressive rates apply to the relevant portions of chargeable income.

For non-resident individuals, the rules are different.

HASiL’s current guidance states that non-resident individuals are generally taxed at a flat 30% on chargeable income and are not entitled to the same personal tax relief treatment available to resident individuals.

Tax residence is therefore an important issue for foreigners working in Malaysia and Malaysians who spend substantial periods outside the country.

Are Foreigners Taxed in Malaysia?

Yes, but the rules depend partly on tax residence and the nature of the income.

Being a Malaysian citizen is not the only factor used to determine individual tax residence.

HASiL’s 2026 guidance explains that individual residence status is determined by physical presence in Malaysia under the relevant provisions of the Income Tax Act 1967. One of the general tests is physical presence in Malaysia for at least 182 days in a basis year, although the legislation contains other circumstances and tests that can affect residence status. (Hasil)

This means an expatriate or foreign national working in Malaysia should not automatically assume that citizenship determines their Malaysian tax status.

Likewise, a Malaysian citizen living overseas should not assume that citizenship alone determines the tax treatment of all their income.

Cross-border situations can become complicated, particularly when income is earned in more than one country. Professional tax advice may be appropriate in such cases.

When Is the Malaysia Income Tax Deadline?

The filing deadline depends on the type of return.

For the 2026 filing programme covering Year of Assessment 2025, HASiL lists:

Resident individual without business income:

• e-BE: statutory due date of 30 April 2026
• Electronic filing receives a 15-day grace period, making the practical e-Filing deadline 15 May 2026 under the 2026 programme.

Resident individual carrying on business:

• e-B: statutory due date of 30 June 2026
• Electronic filing receives a 15-day grace period, making the practical e-Filing deadline 15 July 2026 under the 2026 programme. (Hasil)

HASiL’s general online filing guidance similarly lists 15 May for e-BE and 15 July for e-B, while noting that filing dates can be subject to the current filing programme. (Hasil)

This is an important distinction because older articles may still mention only the statutory dates.

Taxpayers should always check the current HASiL filing programme for the specific assessment year.

What Happens If You Have Tax to Pay?

After completing your return, the system will show whether there is a balance of tax payable or another outcome based on your tax calculation.

If you have tax to pay, you should arrange payment according to the instructions provided through HASiL’s available payment channels.

Do not ignore a tax balance simply because your employer already deducted Monthly Tax Deduction (PCB) from your salary.

PCB is a withholding mechanism during the year. Your annual tax return reconciles your overall tax position based on your actual income and applicable reliefs and deductions.

Depending on the final calculation, you may have additional tax to pay or may be entitled to a refund.

What If Your Employer Already Deducted PCB?

This is another area that can confuse first-time taxpayers.

If you are an employee, your employer may have deducted PCB from your salary throughout the year and remitted it to HASiL.

That does not normally remove the need to submit your annual return if you are required to file.

Instead, the amount already deducted is taken into account when your final tax position is determined.

Think of PCB as payments made during the year, while the income tax return is the annual calculation that brings the numbers together.

What If You Made a Mistake?

Do not panic if you discover an error after submitting your return.

HASiL provides procedures for certain amendments and tax-related applications. Its e-services information includes e-Application for Amended BE, which can be used in specified circumstances involving overstated income or understated allowable exemptions or reliefs after submission. (Hasil)

The appropriate correction method depends on what went wrong and when the error was discovered.

If the mistake involves significant amounts or complicated tax matters, it is safer to check HASiL’s current guidance or speak with a qualified tax professional rather than simply submitting another return.

A Simple First-Time Filing Checklist

If this is your first Malaysian income tax return, having a checklist can make the process less stressful.

Before filing, make sure you have:

1. Your TIN

Check whether you already have a Tax Identification Number.

2. Access to MyTax

Make sure your MyTax account is activated and you can log in.

3. Your EA Form

Employees should have the relevant remuneration information from their employer.

4. Details of other income

Include relevant business, freelance, rental or other taxable income according to the applicable rules.

5. Tax relief information

Gather documents supporting the reliefs you are eligible to claim.

6. Bank information

Keep your bank details updated where relevant, particularly if a refund may be due.

7. Supporting documents

Keep receipts and other evidence supporting your declarations and claims.

8. The correct form

Check whether you should use e-BE, e-B or another return form.

9. The deadline

Check the current HASiL filing programme rather than relying on an old deadline.

10. A copy of your submission

Keep a record of your submitted return and relevant confirmation for your files.

Common Mistakes First-Time Taxpayers Should Avoid

The most common problems are often surprisingly simple.

One is forgetting additional income. Someone may remember their salary but overlook freelance work, commissions or another source of taxable income.

Another is claiming a relief without checking whether the expense actually qualifies.

A third is using an outdated tax-relief list. Tax rules can change from one assessment year to another, so information published several years ago may no longer apply.

There is also the temptation to leave filing until the last day.

Even when the process is entirely online, technical problems, forgotten passwords, missing documents or uncertainty about a tax claim can make last-minute filing unnecessarily difficult.

Starting early gives you time to resolve questions before the deadline.

Income Tax in Malaysia Does Not Have to Be Complicated

For a first-time taxpayer, Malaysian income tax can look like a maze of forms and abbreviations.

Once the process is broken down, however, the basic steps are fairly clear.

Check your TIN. Set up MyTax. Gather your income information. Identify the correct return form. Review your eligible reliefs. Submit the return through e-Filing. Check the resulting tax position and settle any balance due.

The most important habit is to use current information.

Malaysia’s tax rules, reliefs and administrative procedures can change, and filing deadlines can be updated. HASiL’s official portal remains the appropriate place to check the requirements for the particular Year of Assessment you are filing.

For people earning a straightforward salary, the annual return may take relatively little time once the necessary documents are ready. For business owners, freelancers, landlords, expatriates and people with international income, the tax position can require considerably more attention.

If your situation is complicated, getting professional tax advice can be worthwhile.

Final Thoughts

Filing income tax is one of those responsibilities that becomes easier once you have done it once.

The first year is usually the hardest because the terminology is unfamiliar and you may not know which documents matter. After that, much of the process becomes a yearly routine.

Keep your records throughout the year, check your eligibility for reliefs carefully, file through the official MyTax system and pay attention to the applicable deadline.
