When shares in a Singapore private company change hands, the transaction rarely stops at signing a share transfer form. There is a tax to settle first: stamp duty. It is small in percentage terms, but the deadline is tight, the valuation rules trip people up, and the penalties for missing the window are out of proportion to the duty itself. Directors, buyers and sellers who understand the mechanics before they sign avoid an expensive scramble later.
This guide explains how stamp duty on share transfers works in Singapore in 2026: the rate, how the shares are valued, who pays, how to stamp through the IRAS e-Stamping portal, and what happens if you are late. It is written for business owners rather than tax specialists, but the statutory references are included so you can check the source.
What Is Stamp Duty on a Share Transfer?
Stamp duty is a tax on documents, not on transactions. It is charged under the Stamp Duties Act 1929 and administered by the Inland Revenue Authority of Singapore (IRAS). When you execute an instrument of transfer to move shares from one holder to another, that document becomes chargeable with duty. Until it is stamped, it is not admissible as evidence in court and the company secretary should not register the transfer in the register of members.
The duty applies to transfers of shares in Singapore-incorporated companies and to shares registered in a branch register kept in Singapore. It applies whether the transfer is a sale, a gift, or a transfer to a nominee, because the charge attaches to the document.
The Rate: 0.2% of the Higher of Price or Net Asset Value
The rate for a share transfer is 0.2%. What it is charged on is the part people get wrong. Duty is calculated on the higher of:
- the actual consideration (the price the buyer pays); or
- the net asset value (NAV) of the shares being transferred.
This means you cannot reduce the duty simply by recording a low or nominal price. If the company owns valuable assets, IRAS will look to the NAV. IRAS confirmed in its early-2026 updates that the 0.2% rate and the higher-of basis remain unchanged.
A Worked Example
| Scenario | Consideration | NAV of shares | Duty base (higher) | Duty at 0.2% |
|---|---|---|---|---|
| Arm’s length sale | S$500,000 | S$450,000 | S$500,000 | S$1,000 |
| Transfer at S$1 nominal | S$1 | S$300,000 | S$300,000 | S$600 |
| Gift to family member | Nil | S$120,000 | S$120,000 | S$240 |
Note that duty is rounded up to the nearest dollar, and the minimum duty payable on a transfer is S$1.
How the Shares Are Valued
For an unlisted company, NAV is normally derived from the latest available management accounts or audited financial statements: total assets less total liabilities, apportioned to the shares being transferred. IRAS expects the accounts used to be reasonably up to date, so if your last year-end is stale and the balance sheet has moved materially, prepare a fresh management account as at a date close to the transfer.
Where the company holds real property, valuation becomes more involved and a different regime may apply. Companies that are “property-holding entities” can attract Additional Conveyance Duties (ACD) on top of, or instead of, ordinary share duty, and a company buying residential property faces Additional Buyer’s Stamp Duty. If your target owns residential property, take advice before you sign.
Who Pays the Stamp Duty?
The Stamp Duties Act does not dictate who bears the cost; it only says the document must be stamped. In practice, the buyer usually pays, and the share purchase agreement should say so expressly. If the agreement is silent, the parties can agree between themselves, but IRAS will pursue whoever presents the document if the duty goes unpaid. For a clean transaction, put the responsibility in writing.
The Deadline: 14 Days (or 30 If Signed Overseas)
Timing is where most penalties arise. The instrument must be stamped within:
- 14 days of execution if the document is signed in Singapore; or
- 30 days of its receipt in Singapore if it is signed overseas.
The clock runs from the date of signing, not from completion or from when the transfer is lodged with ACRA. Because the transfer cannot be properly registered until the duty is paid, leaving stamping to the last minute can delay the whole transaction, including updating the electronic register of members and any subsequent filing with ACRA.
How to Stamp: The IRAS e-Stamping Portal
Stamping is done online through the IRAS e-Stamping portal. The process is straightforward:
- Log in to the e-Stamping portal using Singpass or Corppass.
- Select the document type (transfer of shares) and enter the transfer details, consideration and the NAV computation.
- The system calculates the duty; pay online by card, PayNow or GIRO.
- Download the stamp certificate and keep it with the share transfer form and the company’s statutory records.
Service Bureaus and e-Terminals at selected locations remain available if you cannot stamp online. Retain the stamp certificate: it is your proof that the document is enforceable and that the transfer can be entered in the register of members.

Penalties for Late or Non-Stamping
If you miss the deadline, IRAS can impose a penalty on top of the duty. The published penalty framework is:
| Delay | Penalty |
|---|---|
| Not more than 3 months late | S$10 or the amount of duty, whichever is greater |
| More than 3 months late | S$25 or 4 times the duty, whichever is greater |
An unstamped or insufficiently stamped document also cannot be used as evidence in court, which can be fatal in a shareholder dispute. Given the duty is often only a few hundred dollars, the sensible course is always to stamp on time.
Transfers That Are Exempt or Reduced
Certain transfers may qualify for relief, including some intra-group reconstructions and transfers under approved schemes. These reliefs are conditional and must be applied for, so do not assume an exemption applies. Note also that a bonus issue or a rights issue is an issue of new shares by the company rather than a transfer between holders, and so is not chargeable with share transfer duty in the same way. Understanding whether your transaction is an issue or a transfer is the first question to settle.
Practical Checklist Before You Sign
- Confirm whether the transaction is a transfer (chargeable) or a fresh issue of shares.
- Prepare an NAV computation from up-to-date accounts.
- Check whether the company holds residential property (ACD/ABSD may apply).
- State in the agreement who pays the duty.
- Diarise the 14-day (or 30-day) stamping deadline from the signing date.
- Stamp via the e-Stamping portal and file the stamp certificate with your statutory records.
Stamp duty on a share transfer is rarely large, but the discipline around it matters. Get the valuation right, stamp within the window, and keep the certificate, and the rest of the transfer, updating the register and any ACRA lodgement, follows cleanly.
Frequently Asked Questions
Is stamp duty payable if I transfer shares for S$1?
Yes. Duty is charged on the higher of the price or the net asset value of the shares, so a nominal S$1 price does not avoid duty if the shares have real value. IRAS will assess duty on the NAV.
Does the buyer or the seller pay?
The law only requires the document to be stamped; it does not fix who pays. By convention the buyer pays, and the share purchase agreement should state this expressly to avoid disputes.
What happens if I forget to stamp the transfer?
A penalty applies (up to four times the duty for delays over three months), and the unstamped document cannot be used as evidence in court or relied on to register the transfer. Stamp within 14 days of signing to avoid this.
