Registering an Income Tax File in Malaysia: e-Daftar, Your TIN and MyTax

Who has to register

Registration is not triggered by being asked for a number. It is triggered by having income that is within the charge to Malaysian tax, and the duty to come forward sits on you, not on LHDN.

• Employees — LHDN's own guidance is to register once annual employment income exceeds about RM34,000 after EPF deduction. If PCB is already being deducted from your pay, you are past this point by definition.
• Anyone with business income — sole proprietor, partner, freelancer, commission agent, online seller. There is no profit threshold. A loss-making first year still needs a file, because the loss is only usable if it is reported.
• Anyone with rental income, Malaysian dividends above the 2% dividend tax threshold, or other non-employment income taking them over the taxable line.
• Anyone disposing of Malaysian property or shares in a real property company — the CKHT return cannot be filed without a tax file, and this is where sellers most often get stuck inside a 60-day deadline.
• Non-citizens working in Malaysia, whether or not they end up resident. The employer's CP22 notification does not substitute for your own registration.
• Companies and LLPs are different: a file is normally opened automatically off the SSM incorporation record, so the C-number usually exists before anyone applies for it. Confirm it rather than assume it.

The RM34,000 line is a registration trigger, not a tax trigger

This is the single most misread figure in Malaysian personal tax. Crossing it means you should have a tax file and should be filing a return. It does not mean you owe tax.

Take RM34,000 of income after EPF. The RM9,000 individual relief brings chargeable income to RM25,000, and tax on that is RM150 on the band to RM20,000 plus 3% on the next RM5,000 — RM300. Because chargeable income is under RM35,000, the RM400 individual rebate applies, and it is larger than the tax. The result is nil.

So the typical person registering for the first time files a return showing zero tax payable, and often gets a refund of the PCB their employer deducted. Not registering does not save you anything; it just forfeits the refund and leaves an unfiled year behind you.

What your TIN looks like

LHDN standardised the tax identification number in 2023. Individual files that used to carry an SG prefix (no business income) or an OG prefix (with business income) now all carry IG, with the same digits as before — only the letters changed. If a form, a portal or a customer rejects your old SG or OG number, replacing the prefix with IG is usually the entire fix.

• An employer's E-number is not the proprietor's IG number. A sole proprietor with staff holds both, and mixing them up is a routine cause of misapplied PCB payments.
• For e-invoicing the TIN is written as the prefix followed by the number with no spaces or dashes, for example IG56987000010.
• If you cannot find your number, the MyTax portal has a TIN search that returns it from your identification number — you do not need to call a branch for this.

Registering through e-Daftar

Registration is done online through e-Daftar on the MyTax portal at mytax.hasil.gov.my. There is no fee and no agent is required.

• Have ready: your MyKad or passport, a scanned copy of it, your mobile number and email, and — if you are registering a business source — the SSM registration certificate and business commencement date.
• Choose the correct file type at the start. Registering as an employee when you actually have business income means the system will expect a Form BE from you rather than a Form B, which is awkward to unwind later.
• A straightforward individual application is usually approved quickly and the TIN is issued on screen or by email; applications where documents need review take longer, so do not leave this to the week of the deadline.
• If you already have a dormant file from an old job, e-Daftar will tell you a file exists instead of creating a second one. That is the correct outcome — reactivate it, do not try to register again.

Getting into MyTax the first time

Having a TIN and being able to file are two separate things. Your first login to MyTax requires a one-time digital certificate registration, and that needs a PIN issued by LHDN. If you were not given one during e-Daftar, you can request it through LHDN's live chat or feedback channels, or at any branch, by producing your identification. Once the digital certificate is set up you log in with your identification number and password, and e-Filing, e-Daftar, e-Duti Setem, ByrHASiL and your tax ledger all sit behind that one login.

Keep the email address on the account current. Refund notifications, assessment notices and PIN resets all go there, and a dead company email from a previous employer is the most common reason people lose access to their own file.

Why so many people suddenly need a TIN

The e-invoicing rollout changed registration from a once-a-year chore into a day-to-day commercial requirement. A supplier issuing an e-invoice has to transmit the buyer's TIN, so business customers now ask for it before they will pay, and a missing or mismatched TIN is one of the most common validation failures in the MyInvois system.

As an ordinary consumer you are not obliged to hand over your TIN. Where a buyer does not provide details, the supplier issues the document against the general public TIN, EI00000000010, and a consolidated e-invoice is submitted instead. The practical rule: give your TIN when you want the invoice in your own name because you intend to claim the expense — a medical bill, a lifestyle purchase, a business cost — and do not bother when you do not.

What your employer does and does not do for you

• A new employer must notify LHDN of your employment on Form CP22 within 30 days of you starting, submitted online through MyTax. That notification is about their obligations, not yours.
• LHDN often opens a file off that notification, which is why some people find they already have a TIN they never applied for. It is not guaranteed, and it does not relieve you of the duty to register.
• PCB deducted from your salary is a payment on account, not a filed return. Being taxed monthly does not mean your year is settled.
• When you leave Malaysia for more than three months, the employer must file CP21 and withhold your final pay until tax clearance is issued — which cannot happen if your file is not in order.

If you should have registered years ago

The answer is almost always to register now and file the back years rather than wait to be found. Failing to notify chargeability and failing to furnish a return are both offences under the Income Tax Act, carrying a fine of RM200 to RM20,000, imprisonment of up to six months, or both. In practice LHDN raises assessments for the open years and adds a penalty on the tax rather than prosecuting — and a voluntary approach is treated very differently from one that follows an audit letter.

There is also no time limit protecting you where no return was filed. The ordinary five-year assessment window runs from the year of assessment, but it does not apply at all in cases of fraud, wilful default or negligence, so an unregistered decade stays open indefinitely.

If the back years genuinely produce no tax — which is common for someone who was below the threshold or had PCB covering everything — the cost of fixing it is paperwork rather than money.

Caveats

Portal names, screens, PIN issuance channels and the registration threshold are operational matters set by LHDN and do change — e-Daftar has moved twice and the TIN prefixes were standardised only recently. Confirm the current process on hasil.gov.my and mytax.hasil.gov.my before relying on any step here, and use official LHDN channels only; there is no legitimate paid service for obtaining a TIN.
