Stamp Duty Self-Assessment (STSDS) in Malaysia

Most stamp duty guidance still in circulation describes a system where you send the document to LHDN, the Collector works out the duty, and you pay what the notice says. For a large and growing share of instruments, that model ended on 1 January 2026 — and with it, the comfortable position that the amount on the notice was somebody else’s problem.

What actually changed

Under the old model, stamping ran through formal assessment: the duty payer submitted the instrument, LHDN processed it, and a notice of assessment came back with a figure. The Collector determined the duty.

Under STSDS, the duty payer completes the stamp duty return — the BNDS, Borang Nyata Duti Setem — assesses the duty themselves, and pays. LHDN’s operational guidelines put it plainly: the assessment is deemed to have been raised on the day the BNDS is submitted, and payment follows without waiting for a notice.

The verification does not disappear. It moves to the back end, as audit.

The three phases

Phase	Effective	Instruments covered
Phase 1	1 January 2026	Leases and tenancies, securities instruments, general stamping
Phase 2	1 January 2027	Transfers of real property not involving a JPPH valuation
Phase 3	1 January 2028	All instrument categories outside Phases 1 and 2

The critical operational point, stated expressly in the guidelines: instruments falling in Phases 2 and 3 retain formal assessment until STSDS is fully implemented for them. Between now and 2028 both systems run in parallel, and which one applies depends on the instrument in your hand.

Note also what Phase 2 excludes. Transfers of real property that do require a valuation by JPPH, the Valuation and Property Services Department, are not in Phase 2 — they fall through to Phase 3. The dividing line is whether an independent valuation is needed, not whether the instrument is a property transfer.

What is in Phase 1

Phase 1 sounds narrow and is not. LHDN’s guidelines list three BNDS categories, all submitted on form PDS 15, with worked examples:

Securities instruments — undertakings or agreements to pay, and assignments or transfers of rights. Examples given include service agreements, licence agreements, equipment rental agreements, annuity payment agreements, kiosk and vending machine space agreements, transfers of membership agreements, transfers of intellectual property and trademark agreements, and absolute assignments of insurance policies.

Leases and tenancies — documents, agreements or novations relating to the rental or lease of immovable property such as houses, offices, factories, shop lots and vacant land. Examples include house lease agreements, land agreements, tenancy agreements, novations of tenancy agreements and Form KTN 15A.

General stamping — all general instruments other than transfers, securities or leases, typically agreements or declarations without consideration. Examples include statutory declarations, house sale and purchase agreements, employment offer letters, company constitutions, insurance policies and immigration bonds. The sale and purchase agreement here is the contract — a general-stamping instrument in Phase 1. It is not the instrument of transfer (the memorandum or deed that actually conveys the property and carries the ad valorem duty); that conveyance is the “transfer of real property” that waits for Phase 2, or Phase 3 where a JPPH valuation is needed.

That third category is where most businesses are now exposed without realising it. Employment contracts and company constitutions are ordinary corporate paperwork, and both are squarely inside Phase 1 from 1 January 2026.

The two payment clocks

This is the detail that costs money, because the numbers are close enough to look interchangeable and are not.

	STSDS	Formal assessment
Payment due	30 days from the deemed assessment date, being the date the BNDS is submitted	14 days from the date the notice of assessment is issued, or the period set by the Collector
Statutory basis	s.36(2) Stamp Act 1949	s.40 Stamp Act 1949

A firm that has run a 14-day internal diary for years will now be early on Phase 1 instruments and — far worse — may apply the 30-day habit to a Phase 2 transfer that still runs on 14 days.

What has not changed

Three things stayed exactly where they were, and assuming otherwise is a common error.

The stamping deadline. Section 47 still requires presentation within 30 days of execution in Malaysia, or 30 days after the instrument is first received in Malaysia if executed abroad. Self-assessment does not buy time.

The late stamping penalty. Section 47A applies RM50 or 10% of the deficient duty, whichever is greater, where stamping happens within three months after the deadline, and RM100 or 20% thereafter. This two-tier structure took effect on 1 January 2025 and replaced the older three-tier scale that began at RM25 or 5% — most published guidance still prints the superseded version.

The duty itself. STSDS changes who computes the duty, not how much it is. The First Schedule rates are untouched.

And one new obligation worth diarising: duty payers must retain the instrument and all related records for seven years from the date the duty was paid.

”Securities” does not mean shares

The single most costly misreading of Phase 1. Sekuriti in the STSDS scope means security and undertaking instruments — agreements to pay or repay, and assignments or transfers of property. LHDN’s operational guidelines define the securities return as covering transfers, assignments and novations of property other than real property, shares and businesses.

Share transfers are expressly listed among the instruments that remain on formal assessment, alongside transfers of real property and transfers of business. They fall into Phase 3 in 2028.

Three practical consequences for share transfers today: you still wait for a notice of assessment, payment runs on the 14-day s.40 clock rather than 30 days, and the 2026 penalty remission programme — which applies only to self-assessed Phase 1 instruments — does not reach them.

The statutory machinery behind it

STSDS is not an administrative rearrangement. Three 2024 statutes rebuilt the assessment provisions of the Stamp Act, and the key sections commenced on 1 January 2026:

• s.35A (Act 863) requires the person to furnish a return in the prescribed form together with the instrument, by electronic medium.
• s.36 (as amended) provides that where a return is furnished under s.35A, the Collector is deemed to have made an assessment and the return is deemed to be an assessment. This is the actual mechanism that replaced adjudication.
• s.35B requires the instrument and all relevant documents to be kept for seven years from the date the duty is paid.
• s.36CA (Act 862) sets the time bar: the Collector may raise an assessment or additional assessment within five years after the date the duty was paid or would have been paid — and at any time where it appears that fraud or wilful default has been committed, or that a person has been negligent.

The penalty provisions arrived with them. Under s.72C, failing to furnish a return is an offence with a fine up to RM10,000, or a Collector-imposed penalty of RM200 to RM2,000 where there is no prosecution. Under s.72D, an incorrect return carries a fine of RM1,000 to RM10,000 plus a special penalty equal to the duty undercharged — or, absent prosecution, a Collector penalty equal to the undercharged duty.

That s.36CA negligence limb deserves attention. It mirrors s.91(3) of the Income Tax Act, and it means a self-assessed instrument stamped carelessly has no limitation period at all.

Where the risk actually moved

The shift is easy to state and easy to underestimate. Under adjudication, a taxpayer who disclosed the instrument and paid the assessed figure had substantially discharged the risk. Under self-assessment, the taxpayer owns the characterisation of the instrument, the choice of First Schedule item, and the computation — and each of those is now auditable.

LHDN has been building the back end for this since before Phase 1 started. Its 6 June 2025 media release records that a Stamp Duty Audit Framework was issued on 1 January 2025, and that stamp duty audit activity had begun nationwide. The employment contract enforcement wave that followed was a direct product of that framework: audits found large volumes of unstamped employment contracts, which is precisely the kind of finding a self-assessment regime is designed to surface.

Expect the same pattern in other instrument categories as Phases 2 and 3 land.

Common mistakes

• Describing stamping as adjudication. For Phase 1 instruments there is no separate adjudication step; the return raises the assessment.
• Applying the 30-day payment rule to a Phase 2 or 3 instrument. Those still run on 14 days from the notice under s.40.
• Assuming Phase 1 is only about tenancies. General stamping sweeps in employment contracts, company constitutions and insurance policies.
• Reading “securities” as shares. Share transfers stay on formal assessment until Phase 3 in 2028.
• Assuming all property transfers move in Phase 2. Only those not requiring a JPPH valuation; the rest wait for Phase 3.
• Quoting the old RM25 or 5% first penalty band. It was replaced on 1 January 2025.
• Treating self-assessment as lower risk because no notice arrives. The absence of a notice is the transfer of risk, not the removal of it.

What’s next

Inventory the instruments your business executes routinely and sort them by phase. Anything in leases, securities or general stamping is live now and should already be running through the BNDS with a 30-day payment diary. Anything that is a property transfer needs a decision on whether a JPPH valuation is required, because that determines whether it moves in 2027 or 2028.

Then check the backlog. If stamp duty audits are already running against the framework issued in January 2025, unstamped historical documents are a known finding rather than an obscure one — and the penalty scale for late stamping starts at RM50 or 10% and doubles after three months.
