Stamp Duty on Shares Singapore
When transferring shares costs 0.2%, and when it doesn’t
Last updated: September 2026
Stamp duty on shares is a tax charged on the instrument used to transfer shares in a Singapore company, calculated at 0.2% of the higher of the purchase price or the shares’ net asset value, and it does not apply to trades of SGX-listed shares settled electronically through the Central Depository (CDP).

Key Takeaways
- Stamp duty on a share transfer is 0.2% of the higher of the consideration paid or the target company’s net asset value per share.
- Shares of SGX-listed companies bought and sold through the Central Depository in scripless, book-entry form do not attract stamp duty, because there is no instrument of transfer to stamp.
- Stamp duty is typically borne by the buyer, though the parties can agree otherwise in the sale agreement.
- The duty must be paid within 14 days of signing the instrument in Singapore, or 30 days if signed overseas, and late payment triggers a penalty.
- Share stamp duty is separate from, and much smaller than, the Buyer’s and Additional Buyer’s Stamp Duty charged on property purchases.

What Is Share Stamp Duty?
Stamp duty on shares is administered by IRAS under the Stamp Duties Act and applies to the ‘instrument of transfer’ used when shares in a Singapore company change hands. This typically covers private, unlisted company shares, as well as any listed shares transferred outside the normal scripless CDP settlement system.
The rate is a flat 0.2%, with no tiers, unlike property stamp duty. It is calculated on whichever is higher: the price actually paid for the shares, or the company’s net asset value (NAV) attributable to those shares, based on its most recent set of accounts, or a more current valuation if IRAS considers the existing accounts outdated.
This form of stamp duty typically comes up in mergers and acquisitions, share buybacks, founders transferring shares to co-founders or investors, gifting shares to family members, and situations where employee share options are exercised and settled via a physical share certificate rather than through CDP.
How Does It Work in Singapore?
The process starts with an instrument of transfer being executed between the parties. This is then e-stamped through IRAS’s e-Stamping portal, where the duty is computed based on the declared consideration and company valuation, and paid. Once stamped, the company’s own share register is updated to reflect the new ownership.
Determining the NAV requires using the company’s latest available set of accounts, or a more recent balance sheet if the existing accounts are outdated. IRAS can query a transaction if the declared price or valuation looks understated relative to the company’s actual financial position.
A crucial exemption applies to on-exchange trades of SGX-listed shares settled in scripless form through the Central Depository. Because these trades never involve a physical or electronic ‘instrument of transfer’ being executed between buyer and seller in the traditional sense, they fall entirely outside the scope of stamp duty. This is the reason a retail investor trading SGX shares through a broker never sees a stamp duty line item on their contract note.
Stamp duty is also relevant beyond straightforward outright sales — it can apply to a declaration of trust over shares, a transfer made as part of a company reorganisation, or shares transferred as part of a divorce settlement, each with its own nuances on whether an exemption or relief applies. This is why founders and family businesses planning a share restructuring are generally advised to check the stamp duty treatment before signing any transfer instrument.
Share Stamp Duty Example
A startup founder sells 200,000 shares in her private company to a new investor for S$2.00 per share, a total consideration of S$400,000. The company’s latest accounts put its NAV at S$1.80 per share, or S$360,000 for that block. Since the consideration is higher than the NAV, stamp duty is calculated on S$400,000: 0.2% of that amount is S$800, payable by the buyer within 14 days of the signed transfer instrument being executed in Singapore. Contrast this with a retail investor buying S$400,000 of DBS shares on the SGX: because that trade settles in scripless form through CDP, no stamp duty applies at all, only the broker’s commission and clearing fees.
Advantages of Share Stamp Duty
- At a flat 0.2%, share stamp duty is far lower than the tiered rates that apply to residential or commercial property transfers in Singapore.
- The scripless CDP exemption means retail investors trading SGX-listed shares through a broker never have to think about stamp duty at all — it only ever surfaces in private or off-exchange transactions.
- The rules are simple and formula-based, a flat 0.2% of the higher of price or NAV, unlike property stamp duty, which involves multiple tiers and an additional buyer’s duty layer.
- e-Stamping through IRAS’s online portal is quick and can usually be completed the same day the instrument is signed.
Risks and Limitations
- Buyers in private company transactions sometimes overlook the stamp duty step entirely, only discovering the requirement once IRAS’s e-Stamping system flags the missing filing, along with a late-payment penalty.
- Using an outdated NAV figure instead of the company’s current financial position can understate the duty owed and trigger a reassessment plus penalty later.
- Family share transfers, such as gifting shares to a child or spouse, are not automatically exempt from stamp duty — most such transfers remain dutiable unless a specific exemption applies.
- Because the CDP exemption only covers scripless, on-exchange trades, a private sale of SGX-listed shares conducted off-exchange, or a transfer into a family holding company, can still be a dutiable instrument.
- Determining an accurate NAV for a private company without a recent independent valuation can itself be a source of disagreement, particularly for fast-growing companies whose latest audited accounts no longer reflect their current financial position.
Share Stamp Duty vs Property Stamp Duty (BSD/ABSD)
Singapore’s stamp duty regime treats shares very differently from property, both in rate structure and in how broadly it applies.
| Feature | Stamp Duty on Shares | Buyer’s Stamp Duty (Property) |
|---|---|---|
| Rate structure | Flat 0.2% of the higher of price or NAV | Tiered, from 1% up to 6% depending on the price band |
| Additional surcharge | None | Additional Buyer’s Stamp Duty (ABSD), up to 60% for certain buyer profiles |
| Common exemption | SGX-listed shares traded in scripless form via CDP | None — Buyer’s Stamp Duty applies to almost all residential and non-residential property purchases |
| Typical trigger | A private company share sale, transfer, or gift | The purchase of any residential, commercial, or industrial property |

The Bottom Line
Share stamp duty in Singapore is a low, flat 0.2% cost that almost every private company share transaction has to budget for, while the exemption for scripless CDP trades is precisely why the average SGX retail investor has never had to think about it. Knowing which side of that line a transaction falls on is the whole ballgame.
