Most directors of Singapore companies handle share transfers as a routine corporate secretarial step — sign the instrument, update the register, file the relevant ACRA notice. What they often miss, or postpone, is the stamp duty obligation. Singapore stamp duty on share transfers is administered by IRAS, runs to a real number on most transactions, and attracts compounding penalties when not paid within the 14-day window.
This guide covers when stamp duty applies on Singapore share transfers in 2026, how to calculate it (including the net asset value rule), how and where to e-stamp, exemptions, and the most common mistakes that cause penalties.
1. Legal foundation
Stamp duty in Singapore is governed by the Stamp Duties Act 1929 and administered by IRAS. The First Schedule of the Act lists the instruments that attract duty. A share transfer of a Singapore-incorporated company is the most commonly stamped instrument outside property transactions.
Important: the duty arises on the instrument (the transfer document), not on the underlying transaction. Where the parties skip a formal instrument and effect the transfer by some other mechanism, IRAS still applies the equivalent duty under the deeming provisions of the Act.
2. When stamp duty applies
Stamp duty applies whenever the legal or beneficial ownership of shares in a Singapore company changes through a written instrument. Typical triggers:
- Sale of existing shares between two parties (with or without consideration);
- Gift of shares;
- Transfer of shares pursuant to a court order;
- Distribution of shares from one Singapore holding entity to another;
- Transfer of shares to a trustee.
Stamp duty does not apply to a fresh allotment of new shares — only to the transfer of existing shares. See our guide on allotting and transferring shares for the underlying corporate steps.
3. How much stamp duty applies — the rate
The headline rate in 2026 is 0.2% of the higher of the consideration paid or the net asset value (NAV) of the shares transferred. Rounded up to the nearest dollar.
| Basis | Use when |
|---|---|
| Consideration | Arm’s length sale at market value |
| Net Asset Value | Sale at undervalue, gift, related-party transfer, or where NAV exceeds consideration |
NAV is computed on the most recent management accounts of the company, adjusted to reflect fair value of the assets and liabilities. For listed shares, the basis is the average price on the SGX on the date of execution.
4. Worked example
Suppose A transfers 5,000 shares in ABC Pte Ltd to B for S$200,000. ABC’s NAV per share, based on management accounts, is S$50 (i.e. S$250,000 for 5,000 shares).
- Consideration: S$200,000
- NAV: S$250,000
- Stamp duty base: higher of the two = S$250,000
- Stamp duty payable: 0.2% × S$250,000 = S$500
5. The 14-day deadline and penalties
The instrument must be stamped within 14 days of execution if executed in Singapore, or within 30 days of receipt in Singapore if executed overseas.
Penalties for late stamping (Section 46 of the Stamp Duties Act):
| Period of delay | Penalty |
|---|---|
| Not more than 3 months late | S$10 or the duty payable, whichever is greater |
| More than 3 months late | S$25 or 4× the duty payable, whichever is greater |
Unstamped or insufficiently stamped instruments cannot be used in court as evidence — a major risk if there is a future shareholder dispute, exit transaction or audit.
6. How to e-stamp
Stamp duty on share transfers is paid electronically through the IRAS e-Stamping portal at mytax.iras.gov.sg. Steps:
- Log in with the buyer’s or transferee’s Singpass or Corppass.
- Select Stamping > Share Transfer.
- Enter the company UEN, the number of shares transferred, the consideration and NAV per share.
- Upload the executed Working Sheet D (NAV calculation) and the Instrument of Transfer.
- Pay via PayNow, GIRO or credit card.
- Download the Certificate of Stamp Duty and attach it to the executed instrument.
The certificate is the proof of stamping that ACRA and the courts rely on.
7. Exemptions and reliefs
Limited reliefs are available:
- Section 15 relief for reconstructions and amalgamations — applies to transfers within a wholly-owned corporate group, subject to a 2-year holding period and an undertaking that the relief will not be clawed back;
- Transfers to / from a bare trustee — no change in beneficial ownership, no duty;
- Acquisition of shares as security only — not a beneficial transfer.
The Section 15 application must be made through the IRAS e-Stamping portal with full supporting documents (group structure, board resolutions, shareholder agreements).
8. Stamp duty under the Additional Conveyance Duty (ACD) regime
Where the Singapore company holds Singapore residential property and the transfer involves a “significant owner” (50% or more), Additional Conveyance Duty (ACD) applies — typically on top of the 0.2% basic share transfer duty, at the prevailing residential conveyance duty rates. ACD is a major exposure for property holding companies and family investment vehicles and should be considered before structuring share transfers in such entities.
9. Common mistakes
- Forgetting NAV. Many family transfers happen at S$1 token consideration. NAV will almost always be higher and is the correct base.
- Filing ACRA notice before stamping. ACRA will accept the share transfer, but unstamped transfers create future audit issues.
- Backdating instruments. The 14-day clock starts from actual execution, regardless of the date typed on the document.
- Forgetting ACD. Property-holding companies need separate ACD assessment.
- Group relief without filing. Section 15 relief is not automatic; it must be applied for.
10. How Raffles Corporate Services helps
We prepare the instrument of transfer, compute NAV with reference to your latest accounts, e-stamp the document on IRAS within the 14-day window, update the share registers and electronic share certificates, and lodge the ACRA notification of transfer. For group reorganisations we coordinate the Section 15 application from start to finish. This avoids the most common cause of stamp duty penalties: clients who execute first and ask questions later.
For Singapore directors, stamp duty on share transfers is one of those low-noise compliance items that quietly compounds into a significant problem when ignored. Stamp on time, on the right base — and you can put it out of mind.
