e-Filing Malaysia 2026: Deadlines, Steps & Penalties

e-Filing Malaysia 2026 takes about twenty minutes and costs nothing — right up until the moment it does not. The form is free. The penalty for being late is a percentage of everything you owe.

The tax you see added to a restaurant or clinic bill is a different tax, run by a different agency — that one is covered in our SST guide.

The part that catches people is not the form. It is the login: certificate expired, password forgotten, the email on file belonging to a job you left years ago, five wrong tries and the account locks. Alamak.

Quick Answer: you file through MyTax at mytax.hasil.gov.my. Form BE — employment income, no business — is due 30 April, with additional time to 15 May for e-Filing. Form B, for business income, is due 30 June, with additional time to 15 July.

• Who needs a tax number: employment income above RM 34,001 a year after EPF if you are single, RM 46,001 if married with a non-working spouse. Business owners register even at a loss. This is the registration threshold, not the full filing duty — see below.
• Cost: nothing. e-Filing has been mandatory for individual forms since Year of Assessment 2023.
• Refund: 30 working days after e-Filing, 90 working days after a paper form.
• Late: 15% of tax payable up to 12 months, then 30%, then 45%.

Below: whether you have to file at all, how to get in, which form is yours, what the dates really mean, and what to do if one has already gone past.

Do You Even Have to File?

Two questions get muddled here, with different answers: whether you need a tax number, and whether you need to file a return.

On the number, LHDN is specific: employment income above RM 34,001 a year after EPF deduction if you are single, above RM 46,001 if married with a non-working spouse. Also anyone running a business, even at a loss, any new employee subject to Monthly Tax Deduction, and anyone buying or selling real estate.

⚠️ Editor’s Note: everyone quotes the threshold as RM 34,000. LHDN’s own FAQ writes RM 34,001. One ringgit — and a fair warning about how much Malaysian tax advice online is a copy of a copy.

The duty to file comes from section 77 of the Income Tax Act 1967: you file if you have taxable income for the year, or had taxable income, filed, or were required to file in an earlier year of assessment. Income is not only salary — LHDN counts business profits, dividends and interest, rent and royalties, pensions and annuities. Whether that income can be taxed is one question; whether you are allowed to move money across the border at all is a separate one with a separate regulator — see this site’s guide to sending money overseas from Malaysia.

One real exemption exists. MTD as Final Tax, available since Year of Assessment 2014, lets a salaried employee skip the return if all five conditions hold: one source of employment income under section 13; MTD deducted under the Income Tax (Deduction from Remuneration) Rules 1994, or nil because you earn below the deductible level; the same employer throughout; tax not borne by the employer; no joint assessment. Changed jobs mid-year? You file.

Step 1: Your Tax Number, and Your First MyTax Login

Most Malaysians already have a Tax Identification Number without applying for one: LHDN registers it automatically for citizens and permanent residents aged 18 and above from JPN data. Check it on MyTax, at any HASiL office, or on 03-8911 1000.

Outside that group — a foreign national, a temporary resident on MyKAS — you apply through e-Daftar on MyTax, the only route for an individual since 1 January 2024. Bring a valid passport copy or the relevant pass, or a MyKAS copy; business owners add the SSM certificate.

MyTax accepts MyKad, MyPR or MyKAS, or a passport, and offers MyDigital ID — our MyDigital ID guide covers that. First time in, the system replies Digital Certificate does not exist and offers two ways to create one: e-CP55D through the web form, or e-KYC through face identification.

Two things about that certificate. It is valid for 3 years, renewed by clicking Agree on the message MyTax shows you. And you get five login attempts before it locks temporarily, after which the reset link goes to the email registered with HASiL. If that address is dead, fix it first — not at 11pm on the deadline.

Step 2: Pick the Right Form

There are five. Business or not and resident or not choose most of them; a further status — knowledge or expert worker — narrows BT and MT beyond that.

• Form BE — resident individual who does not carry on business. The salaried default.
• Form B — resident individual with business, employment and other income.
• Form M — non-resident individual with business, employment and other income.
• Form BT — resident knowledge or expert worker.
• Form MT — non-resident knowledge worker.

Online they carry an e- prefix, and since Year of Assessment 2023 that is a requirement: the Filing Programme lists e-BE, e-B, e-BT, e-M, e-MT, e-P, e-TF and e-TP as mandatory. Residence is decided under section 7 of the Income Tax Act 1967 on day counts, case by case — if your year in Malaysia was fragmented, settle that with LHDN or a licensed tax agent first.

Step 3: Fill It In, Sign It, Keep the Acknowledgement

LHDN’s own training deck reduces e-Filing to four steps: get the PIN number and digital certificate, log in to the e-Form, review the prefilled data and complete it, then sign digitally and submit.

The word doing the work is review. Your employer uploads your remuneration through e-Data Praisi / e-CP8D and LHDN prefills it into your e-Form; you may amend it before signing, and the figure you sign is the figure you answer for. Cross it against the EA or EC form your employer must give you on or before 28 February 2026 for the year ended 2025, under subsection 83(1A). Employers upload between 1 January 2026 and 25 February 2026, so an e-Form opened very early may be empty.

You attach nothing — LHDN does not want documents with the return. You keep them for 7 years from the year you filed: EA or EC form, dividend vouchers, insurance premiums, donation and zakat receipts, birth and marriage certificates. Not keeping proper records is its own offence under section 119A: RM 300.00 to RM 10,000.00, imprisonment not exceeding 1 year, or both. Whether a particular receipt has to be an e-Invoice is a separate LHDN rule, covered on its own page.

Reliefs are claimed inside this same form but run on a different clock, so we keep that list separate — see our Malaysian income tax relief guide.

The Dates That Decide Everything

Worth reading twice, because LHDN publishes the deadline in two places that look like they disagree — and do not.

The Income Declaration page presents 15 May and 15 July as the online deadlines. The Filing Programme calls those same dates tambahan masa — additional time after a statutory deadline of 30 April and 30 June. LHDN’s own worked example shows why that matters:

A Form e-BE for Year of Assessment 2025 submitted on 16 May 2026 is treated as received late from 1 May 2026 — not from 16 May — and may be penalised under subsection 112(3). Form e-B is the same: file on 16 July 2026, and you are late from 1 July 2026.

So the grace is real and worth using, but it is not a new deadline. The same additional time covers payment of the balance of tax under subsection 103(1) for e-Filing returns. LHDN prints its own caveat too: the online dates may be subject to change, and each year gets its own Filing Programme.

Paying the Balance, and Getting the Refund

Filing and paying are separate acts sharing one deadline. If your Monthly Tax Deduction came up short — or your CP500 instalments did — the difference is due by 30 April or 15 May, and 30 June or 15 July for business cases.

Payment goes through ByrHASiL on FPX internet banking, or through HASiL collection agents by counter, ATM, telebanking or cash deposit machine. Have your income tax number, identification number, year of assessment and payment code ready — for individuals that is 084 or 095 — and keep the receipt.

Miss the payment and a 10% increase lands on the unpaid balance; leave it and that penalty 60 days from the date imposed and a further 5% follows. LHDN does take instalment appeals, by letter to the collection unit before 30 April or 30 June — while stating plainly that the late payment penalty still applies even when approved.

If you overpaid

Nothing to apply for. LHDN’s Client Charter puts the refund at 30 working days after e-Filing and 90 working days after a manual submission; a cheque is processed within 14 working days of approval. File late and the refund only moves after the late-filing penalty is imposed — the quiet reason a late return costs you twice.

If You Missed It, or Got It Wrong

Missing a deadline does not end the process. It changes which rules apply to you.

That last row is not decoration: LHDN states that a travel restriction — a stoppage order — can be imposed where tax arrears are outstanding, which is how some people find out — at the airport.

Fixing a mistake after you filed

Before the deadline: write to the HASiL office handling your file, describe the error, attach the documents. After it, the door narrows. A taxpayer who filed on time may submit an Amended Return Form up to 6 months after the due date, once per year of assessment, for income under-declared or claims and reliefs over-claimed. From Year of Assessment 2019 it carries an increase in tax of 10% under subsection 77B(4).

For anything outside those categories LHDN says not to use that form — send a detailed notification letter with supporting documents instead. And if you filed late, self-amendment is not open to you; that conversation happens with the office handling your file.

Walaoeh Verdict

The form is not the hard part. The account is. Almost every e-Filing horror story in Malaysia is really a story about an expired digital certificate, a forgotten password and an email nobody updated — discovered in the last week of April, when the Contact Centre is busiest. Log in once in March, while nothing is at stake.

And treat 15 May and 15 July as a cushion, not a deadline. LHDN gives the extra days, then backdates lateness to 1 May or 1 July if you burn them and still miss. One day past the grace period is a fortnight late in LHDN’s ledger, with a percentage attached.
