Most share transfers in a Singapore private company involve more paperwork than the parties expect. The transfer instrument has to be drawn up, signed, stamped at the Inland Revenue Authority of Singapore (IRAS), and then lodged with the company so that the share register can be updated and the directors’ resolution recorded. Stamp duty is the part of that process most often overlooked — and where the late-payment penalty is most punishing.
The rate looks deceptively simple: 0.2% of the higher of the purchase price or the value of the shares. The complications are in the valuation method, the 14-day clock, and the documentation that IRAS expects to see. This guide walks through how to stamp a Singapore share transfer correctly in 2026, the worked examples that catch most people out, and how to fix things if the deadline has already passed.
For an end-to-end mechanic of share transfers (transfer forms, board resolutions, share register updates), see our companion piece: How to Allot & Transfer Shares in a Singapore Company.
What Triggers Stamp Duty on Shares
Stamp duty under the Stamp Duties Act 1929 is payable on every “instrument” relating to the transfer of shares in a Singapore-incorporated company. The principal triggers are:
- a sale and purchase of shares (whether between unrelated parties or within a group);
- a gift or transfer of shares by way of love and affection;
- a transfer of beneficial interest under a declaration of trust or contract for sale;
- certain mortgages or charges over shares.
Stamp duty is a tax on the document, not on the transaction. Even a transfer at zero consideration can attract duty if the underlying shares have value, because IRAS will look through the stated price to the market value or net asset value of the shares.
The Rate and the Valuation Rule
The headline rate is 0.2% of the higher of:
- the actual purchase price (or other consideration) shown on the transfer instrument; or
- the value of the shares as at the date of the document.
For a private limited company, “value of the shares” is generally the net asset value (NAV) per share derived from the company’s most recent management or audited accounts. For a newly incorporated company that does not yet have a year-end (typically less than 18 months old), the allotment price of the shares is generally accepted by IRAS as the value.
Worked Example 1: Transfer at NAV
Company A has 100,000 ordinary shares in issue. Audited accounts show net assets of S$1,500,000. NAV per share is therefore S$15. A founder transfers 10,000 shares to a new investor for S$150,000.
Stamp duty = 0.2% x S$150,000 = S$300. Both consideration and NAV produce the same number; either base produces the same duty.
Worked Example 2: Below-Value Transfer
Same company. The founder transfers 10,000 shares to a family member for S$10,000 (well below NAV). IRAS will value at 10,000 x S$15 = S$150,000.
Stamp duty = 0.2% x S$150,000 = S$300, even though the cash consideration is only S$10,000.
Worked Example 3: Newly Incorporated Company
Company B was incorporated four months ago. Founder shares were issued at S$1 each (allotment price). The founder transfers 5,000 of his shares to a co-founder at S$1 each.
Stamp duty = 0.2% x S$5,000 = S$10.
The 14-Day Clock
The transfer instrument must be stamped within:
- 14 days of execution if the document is signed in Singapore;
- 30 days of receipt in Singapore if the document was signed overseas.
The clock runs from the date the document is signed, not from the date of any related sale and purchase agreement. A common error is to defer signing the share transfer form until the day the cash is received, which is often after the SPA was signed. That can be fine — but only if the transfer form itself is stamped within 14 days of its signing.
How to e-Stamp via IRAS
- Log in to the IRAS e-Stamping portal using SingPass or CorpPass.
- Select “Share Transfer” as the document type.
- Enter the company UEN, transferor and transferee particulars, number of shares and consideration, and (if applicable) the NAV per share.
- Upload the executed transfer instrument and any supporting valuation documents.
- Pay the duty by GIRO, eNETS or credit card. The system will issue a stamp certificate which is then attached to the transfer instrument.
The stamp certificate is what the company secretary needs in order to update the share register and record the transfer. Without a valid stamp certificate, the directors should not register the transfer — an unstamped transfer instrument is not admissible in evidence in Singapore (subject to limited exceptions).
Late-Payment Penalties
If you miss the 14-day window, IRAS imposes a penalty in addition to the duty:
- Up to 3 months late: penalty is the higher of S$10 or the duty amount;
- More than 3 months late: penalty is the higher of S$25 or 4x the duty amount;
- Wilful evasion attracts higher penalties under the Stamp Duties Act.
The “4x the duty” multiplier is what turns a S$300 mistake into a S$1,200 problem on a routine transfer. For a high-value strategic share sale, the penalty alone can run into five figures.
Reliefs and Exemptions
Several reliefs reduce or eliminate stamp duty on share transfers:
- Section 15 relief for transfers within a 75%-owned corporate group (subject to claw-back if the group test is later breached);
- Reconstruction relief on certain qualifying group reorganisations;
- certain transfers to and from public unit trusts and approved Section 13O/13U funds in family-office structures;
- specific exemptions for transfers to the bare trustee of a discretionary trust where there is no change of beneficial ownership (subject to documentation).
Reliefs are not automatic. The transferor must apply for the relief at the time of e-stamping, supplying the supporting documentation (group structure chart, copies of trust deeds, board resolutions). Family-office deal teams should also see our Section 13O vs 13U comparison before structuring contributions or distributions.
Common Mistakes That Cost Real Money
- Stamping the SPA but not the transfer form. Both can attract duty; the transfer form (Form 24) is the decisive instrument for the share register.
- Using stale accounts. NAV must reflect the most recent set of accounts. Where significant time has passed, IRAS may require management accounts brought up to date.
- Treating intra-group transfers as duty-free. Section 15 relief requires a positive application. Without it, the duty is payable.
- Forgetting CPF/contingent assets and liabilities in the NAV computation. NAV is not the figure on the face of the balance sheet — items such as deferred tax, employee bonuses or earn-out liabilities should be considered.
- Late filing because the cash didn’t arrive. The transfer instrument’s signing date triggers the clock, regardless of completion mechanics.
Documentation You Should Keep
For each share transfer, retain (and link to the entry in the statutory share register):
- the executed transfer instrument bearing the IRAS stamp certificate;
- the directors’ resolution approving the transfer;
- the cancelled and re-issued share certificates;
- any valuation report or NAV computation supporting the duty calculation;
- copies of any group-relief applications and supporting documents;
- updated RORC entries if the transfer changes the controller landscape.
