Stamp Duty in Singapore
Stamp duty in Singapore is charged on documents that transfer shares and property, and it is due within 14 days of signing. Share transfers pay 0.2%, property buyers pay BSD and often ABSD, sellers may pay SSD, and deals in residential property-holding companies can trigger additional conveyance duties. This guide explains rates, valuation, reliefs and the traps.
Key pointDuty is charged on the higher of the price and the value, so a share deal for a company holding appreciated property can be stamped on a net asset value well above the agreed price.
At a glance
Fourteen-day deadline
Documents must be stamped within 14 days of signing in Singapore, or 30 days after receipt if signed abroad; late penalties reach four times the duty.
Share duty at 0.2%
Charged on the higher of price and value; private company shares use NAV from accounts within 24 months, with property at market value.
Four-year SSD period
Residential property bought on or after 4 July 2025 attracts SSD of 16%, 12%, 8% and 4% on sales within four years.
ACD on residential PHEs
Buying 50% or more of a residential property-holding entity attracts BSD plus 65% ABSD on the underlying property's market value.
Group reliefs exist
Section 15 relief may apply between entities linked by at least 75% voting capital, but not where ACD applies or between VCCs.

What stamp duty in Singapore covers
Stamp duty in Singapore is a tax on documents, not on transactions as such. It applies to instruments that transfer or deal with immovable property in Singapore and with stock or shares: share transfers, sale and purchase agreements, options to purchase, leases, mortgages, declarations of trust and certain gifts. If a dutiable document is executed, duty is payable whether the deal is a routine share sale or a large property acquisition.
That document-based design produces some counter-intuitive results. An email exchange that concludes a share sale can be a dutiable electronic document. A transfer of scripless shares that are held through the Central Depository, with no transfer document, can attract no duty at all. And because duty attaches at signing, it is often payable long before money changes hands.
For businesses the main exposures are share duty on acquisitions, buyer's and seller's stamp duties on property, additional conveyance duties when buying or selling companies that hold residential property, and lease duty on commercial premises. Each has its own base, rate and pitfalls, explained below.
The legal framework, deadlines and penalties
The Stamp Duties Act 1929 imposes the duties and sets out the reliefs, and the Inland Revenue Authority of Singapore (IRAS) administers them. Stamping is done electronically through the e-Stamping service on myTax Portal, which issues a stamp certificate as proof of payment.
The timing rule is strict. According to IRAS's guidance on when to pay stamp duty, a document must be stamped within 14 days after it is first signed in Singapore, or within 30 days after it is received in Singapore if signed overseas. Late payment draws a penalty of S$10 or the amount of duty, whichever is greater, for delays of up to three months, and S$25 or four times the duty, whichever is greater, beyond three months.
Where the duty is uncertain, a party can apply to the Commissioner for adjudication, which gives a formal opinion on the duty chargeable for a fee, and can object to an assessment it disagrees with. An unstamped document is not void, but it generally cannot be relied on in court proceedings until it is stamped, and ACRA expects share transfer instruments to be stamped before they are lodged.
| Duty | Applies to | Rate | Base |
|---|---|---|---|
| Share duty | Transfers of stock or shares | 0.2% | Higher of price and value of the shares |
| Buyer's Stamp Duty (BSD) | All purchases of property | Tiered 1% to 6% (residential); up to 5% (non-residential) | Higher of price and market value |
| Additional Buyer's Stamp Duty (ABSD) | Residential property only | 0% to 65% depending on buyer profile | Higher of price and market value |
| Seller's Stamp Duty (SSD), residential | Sales within the holding period | 16%, 12%, 8%, 4% over four years (bought on or after 4 July 2025) | Higher of price and market value |
| Seller's Stamp Duty (SSD), industrial | Sales within three years (bought on or after 12 January 2013) | 15%, 10%, 5% | Higher of price and market value |
| Additional Conveyance Duties (ACD) | Equity in residential property-holding entities | Buyers: BSD plus 65% ABSD; sellers: 12% or 16% | Market value of underlying residential property, pro-rated |
| Lease duty | Leases with average annual rent above S$1,000 | 0.4% | Total rent (four years or less) or four times average annual rent |
Stamp duty on share transfers
Share 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 minimum of S$1. IRAS's page on buying or acquiring shares explains how value is measured, and this is where most disputes arise.
- Listed shares are valued at the average price on the Singapore Exchange as at the date of the document.
- Private company shares are valued at net asset value (NAV), based on the latest accounts dated within 24 months before the transfer. If the company owns property, the property must be taken at market value where book value does not reflect it.
- Companies incorporated for 18 months or less use the allotment price of the shares if the company owns no property; otherwise management accounts reflecting the property's market value are needed, certified by a director or the secretary.
The base therefore depends on the target's balance sheet as much as the price. A buyer paying a discount for a business with valuable land can find the duty calculated on a higher NAV than the price. Where there are preference shares or other classes, NAV is allocated by reference to the rights of each class.
Duty is not limited to sales. Gifts of shares, distributions in specie by a company or on liquidation, and distributions from a deceased estate that do not follow the will or intestacy rules are all dutiable. A declaration of trust that does not change beneficial ownership attracts a fixed duty of S$10, but one that does is charged in full. Contracts for the sale of shares that are not subject to ACD are remitted, so in a typical deal the duty is paid on the executed transfer instrument. Our post on corporate share transfers covers the corporate mechanics.
Stamp duty in Singapore on property: BSD, ABSD and SSD
Property purchases carry the heaviest stamp duty in Singapore, and the duties stack. Every buyer pays BSD; residential buyers may also pay ABSD; and a seller who disposes of residential or industrial property within the holding period pays SSD.
Buyer's Stamp Duty
For purchases on or after 15 February 2023, BSD is charged at 1% on the first S$180,000, 2% on the next S$180,000, 3% on the next S$640,000, 4% on the next S$500,000 and 5% on the next S$1.5 million. Residential property is charged 6% on the remainder above S$3 million, while non-residential property tops out at 5%. BSD is computed on the higher of the price and market value.
Additional Buyer's Stamp Duty
ABSD applies only to residential property. For purchases on or after 27 April 2023, Singapore citizens pay nothing on a first home, 20% on a second and 30% on subsequent homes; permanent residents pay 5%, 30% and 35%; foreigners pay 60% on any purchase; and entities and trustees pay 65%. Housing developers pay 35%, remittable on conditions, plus a non-remittable 5%. Nationals of some countries with free trade agreements with Singapore, such as the United States, are treated like Singapore citizens for ABSD. Since 13 October 2023, ABSD also applies when residential property is distributed in specie to a shareholder on a company's liquidation.
Seller's Stamp Duty and the 4 July 2025 change
The holding period for residential SSD was lengthened for property bought on or after 4 July 2025. For those purchases, IRAS's page on SSD for residential property applies rates of 16% on a sale within the first year, 12% in the second, 8% in the third and 4% in the fourth. Property bought between 11 March 2017 and 3 July 2025 keeps the earlier three-year period at 12%, 8% and 4%. Industrial property bought on or after 12 January 2013 attracts SSD of 15%, 10% and 5% on sales within one, two and three years.
The full buyer-side picture, including Residential Property Act approvals, is on our page on property acquisition in Singapore.
Additional conveyance duties on property-holding entities
ACD closes the gap that would otherwise let residential property change hands through a share sale at 0.2%. IRAS's ACD overview sets out the tests.
- Property-holding entity (PHE). An entity is a PHE if at least 50% of its total tangible assets consist of prescribed immovable property in Singapore, broadly residential property and land zoned residential, mixed residential or White. Holding companies are caught if they hold 50% or more of such entities and the look-through test is met.
- Significant owner. ACD applies where the buyer, with its associates, already holds or will hold 50% or more of the PHE, or where a seller who is a significant owner disposes of interests within the holding period.
- Rates. Buyers pay ACDB of BSD at 1% to 6% plus ABSD at a flat 65%. Sellers pay ACDS at 12% if the interest was acquired between 11 March 2017 and 3 July 2025 and sold within three years, or 16% if acquired on or after 4 July 2025 and sold within four years.
- Base. ACD is levied on the market value of the underlying residential property, pro-rated by the percentage of beneficial interest transferred, not on the share price.
ACD applies in addition to ordinary share duty, and the usual group reliefs are not available where ACD is chargeable. Mixed-use and White-zoned sites are a frequent trap: IRAS deems 100% of the gross floor area of White-zoned land to be residential for ACD purposes. Our post on real estate tax structuring discusses holding structures.
Stamp duty in Singapore is charged on the document, not the deal, so the cheapest structure on paper can be the most expensive once the instruments are drafted.
Leases and mortgages
Lease duty is the most common form of stamp duty in Singapore: modest, but universal. Under IRAS's rules for renting a property, a lease with average annual rent of S$1,000 or less is exempt. Above that, duty is 0.4% of the total rent for a lease of four years or less, and 0.4% of four times the average annual rent for a longer or indefinite lease. Rent includes service, maintenance and furniture charges, excluding GST.
Commercial leases raise specific questions. Where rent includes a percentage of gross turnover, the tenant must estimate the turnover rent and include it, or use the maximum or minimum secured sum where one applies. A premium is charged at BSD rates, and a payment by the landlord for the surrender of a lease is also charged at BSD rates. A genuine licence may not be dutiable, but a licence granted in connection with a lease is. See our page on commercial leasing in Singapore for drafting points.
Mortgages of shares are charged on the loan amount secured, subject to a maximum duty of S$500, and an equitable mortgage of shares signed under hand is exempt. Further mortgages securing additional loans are treated as fresh security. Lenders and borrowers should check the stamping position as a condition precedent in every financing.
Reliefs and remissions
The main reliefs from stamp duty in Singapore for corporate groups are in section 15 of the Stamp Duties Act. Relief from stamp duty may be granted on instruments transferring property or shares:
- Between associated permitted entities, 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. Permitted entities include companies, certain LLPs, statutory bodies and registered business trusts.
- On a reconstruction or amalgamation, where ownership remains substantially the same; for a reconstruction, the owner must retain at least 90% of the assets directly or indirectly after the transfer.
Conditions include a bona fide commercial purpose and holding requirements after the transfer, and a planned material divestment after the restructuring can affect eligibility. The reliefs do not apply to transfers involving residential PHEs where ACD applies, and section 15 does not apply to transfers between variable capital companies, which must instead request remission under section 74 on a case-by-case basis. Other remissions cover matrimonial proceedings, donations to institutions of a public character and aborted sales. Our page on corporate restructuring in Singapore sets reliefs in the wider context.
Apply for section 15 relief before the 14-day stamping deadline, not after the restructuring is complete. If relief is refused or later withdrawn, the full duty is payable, so the transaction timetable should allow time for IRAS questions and the group should be ready to pay the duty if needed.
Stamping a transaction: step by step
- Identify every dutiable document. List options, agreements, transfers, declarations of trust, leases and mortgages, including any concluded by email or e-signature.
- Classify the asset. Determine whether the property is residential, industrial or other, and whether any target entity is a PHE, using current zoning and permitted use.
- Value the base. Obtain NAV from accounts dated within 24 months, with property at market value, or a valuation of the underlying residential property for ACD.
- Confirm the buyer's profile. For residential property, establish ABSD status for every buyer, counting existing properties and any FTA treatment.
- Consider reliefs. Check section 15 conditions or remission options and prepare the application with supporting documents.
- Stamp on time. E-stamp within 14 days of signing in Singapore, or 30 days after receipt if signed abroad, and keep the stamp certificate with the deal records.
- Lodge and register. File the stamped share transfer with ACRA or register the property transfer, and diarise any SSD or ACDS holding period.
Risks and common mistakes
Missing the 14-day deadline because completion is later
Duty runs from signing, not completion. A share purchase agreement or option to purchase signed today is dutiable within 14 days even if the deal completes months later or is conditional on regulatory approval. Parties who wait for completion to stamp can face penalties of up to four times the duty. Build stamping into the signing checklist, budget the cash for it, and check whether a remission for agreements for sale or for aborted deals applies so that duty is not paid twice.
Using the price instead of NAV
Share duty is charged on the higher of price and value. Buyers who negotiate a low price for a company with appreciated property, or who pay a nominal amount for a distressed business with positive book NAV, often under-declare. IRAS can audit stamp duty and impose penalties. Prepare a NAV computation from accounts dated within 24 months, revalue any property to market, and keep the working papers with the transaction file.
Overlooking ACD in a group with residential assets
Groups that hold residential land, serviced apartments or White-zoned sites deep in the structure can be PHEs without realising it. A share sale or internal reorganisation can then trigger ACDB at BSD plus 65% ABSD on the underlying property value, and section 15 relief is not available. Run the asset ratio test at every level of the group before any transfer of equity and consider whether a direct property transfer or a different structure would cost less.
Assuming electronic signing avoids stamp duty
Electronic documents relating to Singapore property and shares are dutiable. IRAS treats an electronic document as executed where and when the electronic signature is applied, which can include an email, a WhatsApp message or a click on a platform. Signing abroad by electronic means does not necessarily defer the deadline. Map where each signatory applies their signature and assume the 14-day period applies unless the analysis clearly supports the 30-day rule.
Holding residential property in the wrong vehicle
Entities pay 65% ABSD on residential purchases, transfers into trusts attract 65% ABSD (Trust) upfront, and selling shares in a residential PHE triggers ACD. For residential investment, the vehicle often costs more in duty than any tax it saves. Compare individual, corporate and trust ownership on entry duty, SSD or ACDS on exit, and the buyer pool that each structure allows.
The cross-border angle
Many Singapore deals are signed outside Singapore. A document signed abroad must be stamped within 30 days after it is received in Singapore, but parties should be able to evidence the date of receipt, and electronic execution can change where a document is treated as signed. Overseas buyers should also check whether their nationality brings FTA treatment for ABSD.
For groups based in Bangladesh, the UK, the UAE or China, Singapore stamp duty interacts with home-country transfer taxes and capital gains rules on the same transaction. A share sale by a foreign parent may be dutiable in Singapore and taxable at home, while an internal reorganisation may need relief in both places. TRW & Co's offices in Dhaka, Chattogram, Sylhet, London, Dubai and China, and its sites in Italy and Switzerland, coordinate those workstreams, working with local counsel where foreign law advice is needed. See our post on M&A tax diligence for the deal-side checks.

Checklist for decision-makers
- Have we listed every dutiable document, including electronic ones?
- Is any target or group entity a residential property-holding entity?
- Is the duty base the price, NAV or market value, and is the valuation evidenced?
- What is each buyer's ABSD profile, and does FTA treatment apply?

Frequently asked questions
01How much stamp duty is payable on a share transfer in Singapore?
Share duty is 0.2% of the purchase price or the value of the shares, whichever is higher. Listed shares are valued at the average SGX price on the document date. Private company shares are valued at net asset value using accounts dated within 24 months, with any property taken at market value. If the company is a residential property-holding entity and the buyer becomes a significant owner, additional conveyance duties also apply.
02When must stamp duty be paid?
A document must be stamped within 14 days after it is first signed in Singapore, or within 30 days after it is received in Singapore if signed overseas. Late payment of up to three months attracts a penalty of S$10 or the duty, whichever is greater; beyond three months the penalty is S$25 or four times the duty, whichever is greater. Duty runs from signing, not completion.
03What changed for Seller's Stamp Duty on 4 July 2025?
For residential property bought on or after 4 July 2025, the SSD holding period increased from three to four years, with rates of 16% for a sale within the first year, 12% in the second, 8% in the third and 4% in the fourth. Property bought between 11 March 2017 and 3 July 2025 stays on the three-year schedule of 12%, 8% and 4%. Additional conveyance duties for sellers rose correspondingly to 16% over four years.
04What are additional conveyance duties?
ACD applies to transfers of equity in entities whose tangible assets are at least 50% Singapore residential property. A buyer who becomes or is a significant owner, holding 50% or more with associates, pays BSD plus 65% ABSD on the market value of the underlying residential property, pro-rated. A significant owner who sells within the holding period pays 12% or 16%, depending on when the interest was acquired.
05Is stamp duty payable on a commercial lease?
Yes, where the average annual rent exceeds S$1,000. Duty is 0.4% of the total rent for a lease of four years or less, or 0.4% of four times the average annual rent for a longer lease. Turnover rent must be estimated and included, and a premium is charged at BSD rates. Duty is due within 14 days of signing, and the lease should state who bears it.
06Can a group restructuring avoid stamp duty?
Section 15 of the Stamp Duties Act offers relief for transfers between associated entities, linked by at least 75% voting capital and more than 50% voting power, and for reconstructions and amalgamations where ownership stays substantially the same. Conditions include a bona fide commercial purpose and post-transfer holding requirements. Relief is unavailable where ACD applies and for transfers between VCCs.
07Are electronically signed agreements subject to stamp duty?
Yes. Electronic documents that effect transactions in Singapore property or shares are dutiable. IRAS treats an electronic document as executed at the time and place the electronic signature is applied, which can include emails, messaging apps and clicks on online platforms. That rule decides whether the 14-day or 30-day deadline applies, so deal teams should record where and when each party signs and stamp on the assumption that the shorter deadline applies.
