Missing a tax deadline feels worse than it usually is. Whether you forgot, couldn’t pull your documents together in time, or genuinely didn’t know you were supposed to file, the situation is almost always fixable. But the longer you leave it, the more it costs you, so if you’ve already missed it, the best time to act is now.

When The Deadline Actually Falls

For the YA2025 season, the deadlines are:

e-Filing via MyTax is now the standard method for most taxpayers, with paper filing rarely used. Most salaried employees fall under Form e-BE, so the deadline to keep in mind is 30 April 2026, with a grace period running to 15 May 2026. 

The grace period is an unofficial buffer that LHDN typically allows after the official deadline. Filing within this window is still considered on time for most practical purposes.

Not sure which form applies to you? Our Malaysia Personal Income Tax Guide (YA 2025) has a full breakdown.

What Happens After If You Miss The Deadline

LHDN doesn’t send an automatic alert the moment the deadline passes. There’s no instant fine, no letter arriving the next morning. What LHDN does is periodically reconcile their records, cross-referencing who’s registered for a tax file against who has actually submitted a return. Eventually, they catch up.

From there, it depends on whether you act first or they do.

If you go to MyTax and submit your return voluntarily, before LHDN formally contacts you, you’re in a better position. Your tax will be calculated normally, and any surcharge (an extra fee added on top of your tax bill) for late filing is typically lower.

If LHDN reaches out first by issuing a Form J (a notice of estimated tax), a surcharge of up to 45% may be applied on whatever tax you owe. You’d then have 30 days from the date on that letter to pay or appeal.

The Penalties, Explained Clearly

There are two different types of penalties, and it’s easy to get confused, so we’ll explain:.

The surcharge for filing late

Under Section 112(1) of the Income Tax Act 1967, failing to submit a tax return at all can theoretically result in a fine of RM200 to RM20,000, up to six months’ imprisonment, or both. That sounds alarming, but this outcome is reserved for persistent non-filers or cases involving suspected tax evasion, not someone who filed two months late.

LHDN may impose a surcharge ranging from 15% to 45% of the tax you owe, depending on how late the filing is and whether enforcement action has already started. The tiers below reflect what typically happens, though LHDN retains discretion in each case:

Do note that if no tax is payable (because your PCB deductions already covered your full liability, or your income falls below the taxable threshold), a surcharge is typically not imposed. That said, late filing still technically breaches your filing requirements under Section 112, so it’s not a free pass.

The penalty for paying late

Separate from the late filing surcharge is a 10% penalty on any tax balance you don’t pay by the due date. This is added on top.

Say you owe RM1,500 in tax and you file voluntarily after eight months. The surcharge would be RM225 (15% of RM1,500). If you then delay paying that balance, a 10% late payment penalty gets added on top. The costs compound, which is why sorting it out sooner is always better.

Two Things About Filing People Get Wrong

“My PCB has already been deducted from my salary every month. That means I’m done, right?”

Not quite. PCB (Potongan Cukai Berjadual, also known as Monthly Tax Deduction or MTD) is your employer deducting an estimate of your tax throughout the year. It’s a prepayment, but it doesn’t replace the annual return.

Filing your return is how you reconcile that estimate with your actual tax liability, and how you claim tax reliefs (deductions that reduce the amount of tax you owe, covering things like medical expenses, lifestyle purchases, life insurance, and education). If you skip filing, you don’t just lose those reliefs. You also technically fail to meet your legal obligation to submit a return, which can still attract a penalty even if you owe nothing.

“My income is too low to pay tax, so I don’t need to file.”

Not everyone needs to file. If you’ve registered a tax file with LHDN and your income meets the threshold for that year, you’re required to submit a return. If you’ve registered and meet the filing criteria for that year, you’re generally required to submit a return, even if your chargeable income (your total income after deducting reliefs and exemptions, which is what LHDN actually taxes you on) turns out to be zero. Not filing when you’re a registered taxpayer is what can get you into trouble, regardless of whether you actually owe anything.

If you’ve never registered and your income is below the threshold, you likely don’t have a legal obligation to file. But if you’re unsure whether you should have been filing all along, it’s worth checking sooner rather than later. LHDN is generally more lenient with people who come forward on their own than with those they have to chase.

What To Do If You Miss The Tax Filing Deadline

If you’ve missed the deadline, the process is exactly the same as filing on time. There’s no special “late submission” form.

1. Go to mytax.hasil.gov.my and log in. If you haven’t registered before, you can create an account using your MyKad number.
2. Select e-Filing and choose the correct form (e-BE for employment income, e-B if you have business income).
3. Complete your return as normal — declare your income, enter your PCB deductions from your EA form (the annual tax summary your employer is required to give you by the end of February each year), and claim your tax reliefs.
4. Once you submit, MyTax will calculate your balance. If you’re due a refund, it’ll be credited to your bank account. If you owe a balance, a 16-digit bill number will be generated.
5. Pay whatever you owe as soon as you can via ByrHASiL (LHDN’s official payment portal) or FPX (the online banking transfer service available through most Malaysian banks). The bill number is required for payment.

If you’ve already received a Form J from LHDN before getting around to this, you’ll still go through e-Filing to submit your actual return. The Form J is LHDN’s estimate and your actual return overrides it once submitted.

Can You Appeal Or Reduce A Late Filing Penalty?

Yes. If LHDN has issued a Form J and applied a surcharge, you have 30 days from the date of the letter to pay or appeal. You can submit an appeal using Form Q (LHDN’s official form for disputing a tax assessment) or a written appeal to your nearest LHDN branch, both are accepted, and your branch can advise which is more appropriate for your situation.

You’ll generally need to have filed and paid the base tax first before the appeal is considered. A clear, factual explanation of why the delay happened helps, especially if there was a genuine reason such as illness or a bereavement.

You won’t win every appeal, but it’s worth attempting if the penalty amount is significant.

Missing Your Tax Deadline Is Fixable

Missing the tax deadline doesn’t make you a criminal. LHDN’s first response is always administrative, a letter, not a visit. The main consequence is a surcharge on whatever tax you owe, which grows the longer you delay.

The fix is to file as soon as possible, pay what you owe, and if a penalty has already been applied, put in an appeal. Most people who deal with this honestly and promptly resolve it without lasting consequences.

For next year, try to set a reminder for 1 April. That gives you weeks to sort everything before the 30 April deadline, which is more than enough time.
