Stamp Duty Self-Assessment (STSDS): What Changed on 1 January 2026

What actually changed

Stamp duty itself did not go up. What changed is who does the assessing. Previously LHDN adjudicated the instrument and issued the amount payable, which meant the taxpayer's exposure was limited — if the officer computed it low, that was the officer's figure. Under self-assessment the duty is whatever the law says it is, you are the one who has to work that out, and an under-declaration discovered later is your liability plus penalty.

The mechanics moved online to the e-Duti Setem (e-DS) platform inside the MyTax portal at mytax.hasil.gov.my. You submit a stamp duty return declaring the instrument and the duty you have computed, then pay. Record-keeping matters more than it used to, because LHDN's role has shifted from front-end assessment to back-end audit.

The three-phase rollout (2026–2028)

Not every instrument moved at once. LHDN staged it so that the highest-volume, easiest-to-value documents went first, leaving valuation-dependent property transfers for later:

• If you are stamping a tenancy or a service or employment agreement today, you are already in self-assessment.
• A sub-sale MOT signed in 2026 is still assessed the old way — property transfers only move across in Phase 2.

The 30-day deadline is the part people miss

The stamping window has not changed and it is short. An instrument executed in Malaysia must be stamped within 30 days of execution. An instrument executed outside Malaysia must be stamped within 30 days of it first being received in Malaysia. Under STSDS the return and the payment both have to land inside that window — declaring on day 29 and paying on day 40 is still late.

Thirty days from signing, not thirty days from when the deal completes or when the tenant moves in. Tenancies signed in advance of the commencement date are routinely stamped late for exactly this reason.

Late stamping penalties under section 47A

Miss the window and the penalty is formulaic — it is charged on top of the duty, and it is the higher of a flat amount or a percentage of the deficient duty:

PKPS 2026: a full penalty waiver that closes 31 December

This is the actionable part. Under the Special Voluntary Disclosure Programme for stamp duty (PKPS Duti Setem 2026), an instrument executed between 1 January 2023 and 31 December 2025 that was never stamped — or was under-stamped — can be regularised with a 100% remission of the late stamping penalty. You pay only the duty itself.

The programme originally ran to 30 June 2026. On 26 June 2026 LHDN extended it to 31 December 2026, so the window is open as this is written but will not be open indefinitely.

• No separate application is needed — the remission is granted automatically when the duty is paid within the programme period.
• Instruments regularised under PKPS will not be subjected to a stamp duty audit.
• It does not cover cases involving fraud or wilful evasion.
• It only reaches instruments executed 1 January 2023 – 31 December 2025. Something signed in 2026 and stamped late attracts the ordinary section 47A penalty.

The separate 2026 grace period for honest mistakes

Distinct from PKPS, LHDN announced on 21 December 2025 that no penalty will be imposed on Phase 1 instruments stamped during 1 January to 31 December 2026 where the problem is a good-faith error — an incorrect stamp duty return, inaccurate instrument details that affected the assessment, or a section 72D(2) exposure picked up on audit.

Read the boundary carefully, because it is where most people assume too much. This grace period forgives getting the numbers wrong. It does not forgive being late. Instruments stamped outside 2026, instruments never stamped at all, and anything outside the STSDS framework fall back on the normal penalties.

New offences that come with self-assessment

Shifting the assessment burden required new enforcement provisions in the Stamp Act 1949. Two matter to ordinary taxpayers:

• Section 72C — failing to submit the stamp duty return. On conviction, a fine of up to RM10,000; or, in lieu of prosecution, a penalty in the range of RM200 to RM2,000.
• Section 72D — under-declaring the duty. On conviction, a fine of RM1,000 to RM10,000 plus a special penalty of 100% of the duty undercharged; or, in lieu of prosecution, a penalty of 100% of the undercharged amount.

Employment contracts: the RM3,000 threshold

Employment contracts are Phase 1 instruments, which caught a lot of employers by surprise. Budget 2026 raised the exemption threshold from monthly remuneration of RM300 — a figure unchanged for generations and effectively meaningless — to RM3,000, with effect from 1 January 2026.

HASiL clarified on 7 August 2026 that where an employee's monthly remuneration does not exceed RM3,000, the employment contract is exempt and does not need to be stamped or endorsed at all. Where it exceeds RM3,000, the main employment contract should be submitted for stamping and endorsement. The duty on a general agreement is nominal — the cost of getting this wrong is the penalty, not the duty.

What to do now

• Audit your drawer. Any tenancy, service agreement, employment contract or loan document signed since 1 January 2023 that was never stamped should go through PKPS before 31 December 2026 — the penalty saving is 10% to 20% of the duty, for no more effort than stamping it normally.
• Register for MyTax and get familiar with e-Duti Setem before you have a 30-day clock running.
• Diarise 30 days from the execution date on every instrument you sign, not from the commencement date.
• Keep the workings for how you computed the duty, along with the instrument. Under self-assessment those workings are your defence in an audit.
• For property purchases, remember the calculator below still applies in the ordinary way — the MOT duty is unchanged, and transfers do not enter self-assessment until 1 January 2027.

Important caveats

This guide explains the administrative shift to self-assessment and the penalty regime around it. It does not tell you how much duty any particular instrument attracts — that depends on the First Schedule to the Stamp Act 1949 and, for property, on the higher of consideration or market value.

Phases, thresholds, penalty rates and the PKPS window are set by LHDN and by amendments to the Stamp Act, and have already moved once in 2026.
