Accepting Your Tax Agent Appointment via MyTax: What Changed and Why It Matters

01At a glance

Your tax agent can no longer act for you on a signed letter alone. Under LHDN's new arrangement, the appointment is made online, and you must log in to MyTax and click Accept before it takes effect.

Picture this. Your agent tells you everything is in order. Filing season comes, and they cannot see your tax account. The reason is not missing paperwork. It is an offer still sitting unaccepted in your MyTax profile.

That is the gap this guide closes. It takes six steps and about five minutes.

Key points for taxpayers and businesses:

• Tax agent appointments are moving from the paper Form CP55 to an electronic appointment in MyTax, linked to LHDN's TAeF 3.0 rollout.
• The tax agent sends the appointment offer. You, the taxpayer, accept or reject it in MyTax.
• For existing appointments, the reported transition window is 2 November to 31 December 2026. An offer with no response is expected to be treated as rejected.
• Electronic appointment is expected to become mandatory from 1 January 2027, with the old e-Form route closing fully on 1 May 2027.

Dates above are as reported in professional alerts and should be confirmed against the latest LHDN announcement before you rely on them.

02Why LHDN made the change

The short answer: LHDN wants you, not your agent, to confirm who speaks for you. The stated policy aim is to automate tax administration and keep agent access to taxpayer information updated in real time. In practice, that breaks down into five reasons.

1. Consent comes directly from you. Under the old process, a signed letter was handed to the HASiL branch. LHDN saw the paper, not the person. Clicking Accept in your own authenticated MyTax account is clear proof that you agreed.

2. Protection against unauthorised access. An agent appointment opens your tax records, returns and correspondence. A forged or outdated letter could give access to the wrong person. Tying acceptance to your MyTax login closes that door.

3. Real-time records. Paper appointments had to be keyed in manually by the branch handling your file. Delays meant agents could not act when it mattered. An electronic acceptance updates your record immediately.

4. A clearer scope for each agent. Under TAeF 3.0, you are reported to be able to appoint up to two tax agents for different tax matters. Each offer names the specific tax return and year of assessment, so everyone knows who handles what.

5. Verified, approved agents only. You are responsible for ensuring your agent is approved by the Ministry of Finance and still within the approval period. The offer shows the firm's name, TIN and agent's name so you can check this before you accept. Under Section 153 of the Income Tax Act 1967, only an approved tax agent may act for reward in preparing returns or handling tax matters for another person.

03Step-by-step: accepting your tax agent appointment in MyTax

Your agent sends the offer first. Once they confirm it is out, follow these six steps.

1. Log in to MyTax. Go to the MyTax portal and sign in with your identification details. For a company, the person holding the director or authorised role logs in.
2. Open Tax Agent Appointment. Click Profile (Profil), then select the Tax Agent Appointment (Lantikan Ejen Cukai) tab.
3. Select the offer. Scroll to the list of tax agent appointments and click Action (Tindakan) on the relevant offer.
4. Verify the details. Check each of these against what your agent gave you:
   • Tax agent firm's name
   • Firm's TIN
   • Tax agent's name
   • Relevant tax return and year of assessment
5. Review the terms and conditions. Read the appointment terms and the authorisation you are granting before you proceed.
6. Accept. Click Accept (Terima). The appointment is confirmed and your agent can act on the matters stated in the offer.

04Common pitfalls to avoid

Most problems are not technical. They come from offers left untouched or details not checked.

• Leaving the offer unanswered. An offer with no response within the prescribed period is expected to be treated as rejected. Your agent then cannot act, and you may face filing deadlines alone.
• Accepting without checking. If the firm name, TIN or year of assessment does not match, do not accept. Ask your agent to resend a corrected offer.
• Accepting an offer you did not expect. If you did not engage that firm, reject it and contact LHDN. An unknown offer is a red flag.
• Assuming one acceptance covers everything. Each offer is tied to a stated tax return and year of assessment. Check whether separate offers are needed for each entity and each tax type.
• Missing access to MyTax. If you have not logged in for years, reset your password or apply for a role well before the deadline. For companies, make sure the right director holds the MyTax role.

You also remain responsible for confirming that your agent is approved by the Ministry of Finance. You can check this on the public tax agent list at mycukai.treasury.gov.my.
