Stamp Duty on Share Transfers in Singapore: Rate, Valuation, Deadlines, Reliefs and ACD
Stamp duty on share transfer in Singapore is 0.2% of the price or the value of the shares, whichever is higher, usually paid by the buyer within 14 days of signing. Private company shares are valued by net asset value with property at market value. Group reliefs can apply, and buyers or sellers of property-rich companies may also face additional conveyance duties.
Key pointDuty is charged on the higher of price and net asset value, using property at market value, so neither a low price nor old book values reduce it; and if the company mainly owns residential property, ACD can far exceed the 0.2% share duty.

Duty is 0.2% of the purchase price or the value of the shares, whichever is higher, rounded down to the nearest dollar, with a S$1 minimum.
NAV for private companies
For companies incorporated over 18 months, IRAS uses net asset value from accounts dated within 24 months, with property at market value.
14 or 30 days
Stamp within 14 days of signing in Singapore, or 30 days after receiving a document signed overseas; late penalties can reach four times the duty.
Group reliefs available
Section 15 reliefs can apply to transfers between associated entities and to reconstructions or amalgamations, if strict conditions are met.
ACD for property companies
Significant owners buying or selling equity in residential property-holding entities may pay additional conveyance duties based on the property's market value.

The short answer: stamp duty on share transfer in Singapore
Stamp duty on share transfer in Singapore is charged at 0.2% of the purchase price or the value of the shares, whichever is higher. It is payable on the document that transfers the shares, usually by the buyer, and must be paid within 14 days of signing in Singapore, or within 30 days of receiving the document in Singapore if it was signed abroad. For private companies, IRAS generally values shares by reference to net asset value.
Two exceptions change the picture. Listed shares held in scripless form through the Central Depository usually pass without a dutiable transfer document. And if the company is a property-holding entity that mainly owns Singapore residential property, a significant buyer or seller may also face additional conveyance duties (ACD) at rates far higher than 0.2%.
This article covers the rate, the valuation basis, timing, reliefs and the ACD regime, with a worked example. For transaction support more broadly, see our stamp duty and M&A support pages.
The legal framework: the Stamp Duties Act and IRAS
Stamp duty is imposed under the Stamp Duties Act 1929 and administered by the Inland Revenue Authority of Singapore (IRAS). It is a tax on documents, not on transactions as such. For shares, the dutiable documents include the contract or agreement for sale and the share transfer instrument, in physical or electronic form, as well as gifts, declarations of trust and settlements of shares.
To avoid double duty, IRAS remits share duty on a sale agreement where the transfer is not subject to ACD; the duty is paid on the executed transfer instrument instead. IRAS also asks parties to make sure the transfer instrument is stamped before it is lodged with ACRA. Its basics for shares page explains which documents are dutiable.
Electronic documents are within scope. A document concluded by email or e-signature is treated as executed when and where the electronic signature is applied, which affects which stamping deadline applies.
How much: the 0.2% rate and the valuation basis
For stamp duty on share transfer in Singapore, the rate is 0.2% of the purchase price or the value of the shares, whichever is higher, rounded down to the nearest dollar with a minimum of S$1. IRAS's share acquisition guidance sets the valuation rules, which differ for listed and private companies.
| Situation | Value used for the 0.2% duty | Points to watch |
|---|---|---|
| Shares listed on SGX | The average price on SGX on the date of the document, or the latest average price if none is available | Scripless trades through CDP usually involve no dutiable transfer document |
| Private company incorporated more than 18 months | Net asset value (NAV) of the shares transferred, based on the latest accounts dated within 24 months before the transfer | Property must be at market value if book value does not reflect it |
| Private company incorporated 18 months or less, no property | Total allotment price of the shares transferred | Simple, but only where the company owns no property |
| Private company incorporated 18 months or less, owns property | NAV from management accounts reflecting market value of property | Accounts must be certified by a director or the company secretary |
| Different share classes | NAV per share allocated according to each class's rights to capital and surplus | Preference rights change the value of ordinary shares |
The higher-of rule is the most important feature of stamp duty on share transfer in Singapore: the parties cannot reduce duty by agreeing a low price. If the price is below NAV, duty is paid on NAV. If the price is above NAV, which is common where a business has goodwill or growth prospects, duty is paid on the price.
Who pays and when
The party liable to pay is usually set by the agreement. Where the document is silent, the Third Schedule to the Stamp Duties Act makes the buyer or transferee liable for a share purchase. In practice, sale and purchase agreements almost always deal with stamp duty expressly, often allocating it to the buyer.
According to IRAS, a document should be stamped before signing, or at the latest within 14 days after signing if signed in Singapore, or within 30 days after receipt in Singapore if signed overseas. Stamping is done online through e-Stamping on the myTax Portal.
- Agree the duty allocation in the SPA. State who pays stamp duty on the transfer instrument and on any related documents, and who bears any penalty for late stamping.
- Gather valuation evidence. Obtain the target's latest accounts within the 24-month window, or management accounts where required, and market valuations for any property.
- Compute duty on the higher of price and value. Work out NAV per share by class and compare it with the consideration, including deferred or contingent consideration where relevant.
- Stamp through e-Stamping. Submit the share transfer instrument on myTax Portal within the deadline and pay the duty.
- Lodge the transfer. Lodge the stamped transfer and update the register of members, following our guide to share transfers.
- Check ACD separately. If the target owns Singapore residential property, test whether it is a property-holding entity before signing.
Late stamping is expensive, and the penalties for stamp duty on share transfer in Singapore escalate quickly. IRAS imposes a penalty of the greater of S$10 or the duty payable for delays up to three months, and the greater of S$25 or four times the duty for longer delays. Its late payment page also explains the reduced penalty available under the Voluntary Disclosure Programme.
Reliefs, remissions and exemptions
IRAS lists several reliefs on its remissions and reliefs page. The two that matter most in corporate work are both under section 15 of the Stamp Duties Act and its subsidiary rules.
Transfers between associated entities
Relief can apply to transfers of shares between associated companies and other permitted entities. Broadly, entities are associated where one holds, directly or indirectly, at least 75% of the voting capital and more than 50% of the voting power of the other, or a common parent holds those interests in both. The association must usually have existed in the same manner for at least 12 continuous months, and the transfer must be for a bona fide commercial reason. Consideration may be at book value only where the entities are wholly associated.
Reconstructions and amalgamations
Relief can also apply where a company acquires an undertaking, or at least 90% of the voting shares of a target, under a scheme of reconstruction or amalgamation in which ownership remains substantially the same. A planned material divestment after the restructuring can defeat the relief.
Neither relief applies to transfers between variable capital companies, and neither is available for residential property-holding entities where ACD applies. Separately, a transfer of shares in a foreign company is exempt where the transfer is registered in a share register kept outside Singapore. Our article on corporate restructuring tax explains how these reliefs fit into group reorganisations.
Relief from stamp duty on share transfer in Singapore is not automatic. It must be applied for, and the conditions, especially the 12-month association period and the post-transfer ownership test, need to be met on the facts. Check eligibility before the group chart is redrawn, not after the documents are signed.
Additional conveyance duties for property-rich companies
ACD applies on top of ordinary stamp duty on share transfer in Singapore where the target is a property-holding entity (PHE). According to IRAS, a PHE is an entity at least 50% of whose total tangible assets consists of prescribed immovable property in Singapore, which is broadly residential or residential-zoned property. A Type 2 PHE is a holding entity whose indirect interests in such property reach the same 50% threshold.
ACD only applies to significant owners: a buyer who, with associates, holds or comes to hold at least 50% of the PHE, or a seller who, with associates, is a significant owner. It does not apply to equity interests acquired before 11 March 2017.
- ACD for buyers (ACDB). For instruments executed on or after 27 April 2023, ACDB is the sum of progressive buyer's stamp duty rates and a flat 65%, applied to the market value of the underlying residential property in proportion to the interest acquired. IRAS sets out the formula on its ACDB page.
- ACD for sellers (ACDS). ACDS applies where a significant owner sells within a holding period: 12% for interests acquired between 11 March 2017 and 3 July 2025 and sold within three years, and 16% for interests acquired on or after 4 July 2025 and sold within four years, applied on a first-in, first-out basis.
Because ACD is charged on the market value of the underlying property rather than the share price, it can dwarf the 0.2% share duty. Any acquisition of a company with Singapore residential property needs a PHE test as part of due diligence. Our pages on property acquisition and real estate tax structuring cover the wider property duties.
Illustrative scenario: buying 60% of a private trading company
This scenario is illustrative only. It uses generic parties and IRAS's published valuation rules.
A buyer agrees to acquire 60% of the ordinary shares in a Singapore trading company incorporated six years ago, for S$3.6 million. The company has only ordinary shares. Its latest audited accounts, dated 10 months before signing, show net assets of S$5 million, including an industrial unit at book value. A recent valuation puts the unit S$500,000 above book.
Because the company was incorporated more than 18 months ago, duty is based on NAV from the latest accounts, adjusted to market value for the property: S$5.5 million in total, or S$3.3 million for 60%. The price of S$3.6 million is higher, so duty is 0.2% of S$3.6 million, which is S$7,200. The industrial unit is not residential, so the company is not a PHE and ACD does not arise.
The SPA allocates duty to the buyer and requires the seller to deliver a signed transfer at completion. The buyer stamps the transfer through e-Stamping within 14 days, then lodges it. Had the company owned residential property making up most of its assets, the analysis would have been completely different: the buyer, as a significant owner, would have had to compute ACDB on the market value of that property as well as the share duty. The seller might also have faced ACDS if it had acquired its shares recently. That is why the PHE test belongs in the first round of due diligence questions, not the completion checklist.
Risks and common mistakes
Using stale or book-value accounts
For a company incorporated more than 18 months, IRAS expects NAV from accounts dated within 24 months before the transfer, with property at market value where book value is not reflective. Using older accounts, or ignoring a property revaluation, can lead to underpaid duty and penalties.
Collect the right accounts and any property valuation before computing duty. Where valuation is uncertain, consider asking the Commissioner of Stamp Duties for an adjudication, which IRAS offers as a formal opinion on duty chargeable.
Missing the 14-day deadline after an electronic signing
Deals signed by e-signature can be executed in Singapore at the moment the last party signs, even if some parties are abroad. That starts the 14-day clock. Treating the deal as signed overseas when it was not can turn a simple stamping into a late-payment penalty.
Record where and when each signature was applied, and stamp as soon as practicable after completion.
Assuming group reorganisations are duty-free
Group relief requires 75% voting capital, more than 50% voting power, a 12-month association period and a bona fide commercial reason. A newly bought shelf company does not count as one incorporated specially for the acquisition, and relief is not available for VCC transfers or residential PHEs where ACD applies.
Map the association chain and dates before any intra-group transfer. Our article on M&A tax diligence lists the documents to request.
Overlooking ACD in a share deal
Buyers sometimes assume that buying shares rather than property avoids property duties. ACD was introduced precisely to address that. A target can be a PHE indirectly, through subsidiaries, and associates' holdings are aggregated for the 50% significant owner test.
Run the PHE asset test on the whole group and the significant owner test including associates, and price ACD into the deal before signing.
Cross-border deals and next steps
Foreign buyers acquiring Singapore companies face the same stamp duty on share transfer in Singapore as local buyers, and the deadlines run from receipt of the document in Singapore if it is signed abroad. Conversely, transfers of shares in foreign companies are generally exempt if registered outside Singapore, although foreign transfer taxes may apply instead.

- Confirm whether the shares are listed, scripless or in a private company.
- Collect accounts within the 24-month window and property valuations.
- Compute duty on the higher of price and NAV, class by class.
- Run the PHE and significant owner tests before signing.
- Allocate duty and penalties expressly in the SPA.
- Stamp within 14 or 30 days, then lodge the transfer.
- Apply for group or reconstruction relief where the conditions are met.

Frequently asked questions
01What is the stamp duty rate on a share transfer in Singapore?
The rate is 0.2% of the purchase price or the value of the shares, whichever is higher. The duty is rounded down to the nearest dollar, with a minimum of S$1. For private company shares, IRAS generally uses net asset value, with property at market value. If the company is a residential property-holding entity and the buyer or seller is a significant owner, additional conveyance duties may also apply at much higher rates.
02Who pays stamp duty on a share transfer?
The agreement usually decides who pays. Where it is silent, the Stamp Duties Act makes the buyer or transferee liable for a share purchase. Most sale and purchase agreements allocate duty expressly, commonly to the buyer, and also say who bears penalties if stamping is late. Because IRAS can pursue the liable party for unpaid duty, sellers should make sure the transfer is stamped before it is lodged.
03When must stamp duty on shares be paid?
IRAS asks for documents to be stamped before signing, or at the latest within 14 days after signing if signed in Singapore, or within 30 days after the document is received in Singapore if signed overseas. Electronic documents are treated as executed where and when the electronic signature is applied. Late payment attracts a penalty of the greater of S$10 or the duty for delays up to three months, rising to the greater of S$25 or four times the duty after that.
04Is stamp duty payable on listed shares bought on SGX?
Trades in scripless shares through the Central Depository usually involve no dutiable transfer document, so stamp duty is generally not payable. Where a dutiable document is signed for a transfer of listed shares, such as an off-market transfer, IRAS values the shares by the average SGX price on the date of the document. Contracts for the sale of scripless shares can qualify for remission of share duty and ACD.
05Can a group reorganisation avoid stamp duty?
Relief may be available under section 15 of the Stamp Duties Act for transfers between associated entities or under a reconstruction or amalgamation scheme. The conditions include ownership thresholds, generally a 12-month association period, a bona fide commercial reason and, for reconstructions, ownership remaining substantially the same. Relief must be applied for and is not available for VCC transfers or residential property-holding entities subject to ACD.
06Does TRW & Co stamp the documents for us?
TRW & Co advises on deal structure, drafting and relief eligibility, and coordinates with your corporate secretary or tax adviser, who usually handles e-Stamping on the myTax Portal. We do not act as a tax agent. Bringing us in at the term sheet stage helps make sure duty is allocated, valued and timed correctly before documents are signed, and that any relief or ACD analysis is done while the structure can still change.
