For illustration onlyStamp Duty on a Grand Dunman Home in Short
Every purchase at Grand Dunman carries Buyer’s Stamp Duty (BSD), calculated on whichever is higher of the purchase price and the market value. Many purchases also carry Additional Buyer’s Stamp Duty (ABSD), which depends on who is buying and what they already own. Seller’s Stamp Duty (SSD) is a separate matter, a cost for the seller on a resale within four years.
The figures in this article are the IRAS rates as read on 22 October 2026, the same rates the site’s calculator uses.
How Buyer’s Stamp Duty Works at Grand Dunman
BSD is charged in six slices of the price, each at its own rate, and the slices are added together. The first slice is taxed at 1%, each later slice at a higher rate, up to 6% on whatever exceeds the top threshold. This residential scale has applied since 15 February 2023.
The stamp duty page lists the band amounts and works through an illustrative example, and the stamp duty calculator runs the same slices on any figure entered and then adds the ABSD for the profile chosen.
ABSD Rates for Grand Dunman Buyers
ABSD is one flat rate on the whole price. An individual’s rate is set by residency status together with the number of residential properties already held at the time of the purchase, while foreigners and entities pay a single rate regardless of what they hold. These rates apply to purchases made on or after 27 April 2023.
| Buyer profile | First property | Second property | Third and subsequent |
|---|---|---|---|
| Singapore Citizen | 0% | 20% | 30% |
| Singapore Permanent Resident | 5% | 30% | 35% |
| Foreigner | 60% | 60% | 60% |
| Entity | 65% | 65% | 65% |

Reading the table, a first home bought by a Singapore Citizen attracts no ABSD at all, which leaves BSD as the only duty, whereas a Permanent Resident’s first home attracts ABSD at 5% of the price.
Reliefs and Foreign Buyers at Grand Dunman
Some purchases qualify for relief. A married couple buying together, with at least one Singapore Citizen and no other residential property between them, may seek remission of ABSD. A couple who buy a new home before selling the old one can apply for a refund if the earlier home is disposed of within the period IRAS sets.
Free trade agreements extend Singapore Citizen treatment for ABSD to nationals of Iceland, Liechtenstein, Norway and Switzerland, and to both nationals and permanent residents of the United States. As a private condominium, the development is open to buyers of every residency status, whether Citizen, Permanent Resident or foreigner, and a foreigner does not need the separate approval that landed homes call for.
The Three Duties at Grand Dunman Side by Side
The three duties work quite differently, and only two of them fall on the buyer. The table sets them out together.
| Duty | Who pays | How it is worked out | When |
|---|---|---|---|
| Buyer’s Stamp Duty | Every buyer | Six slices of the price or market value, whichever is higher | Within 14 days of the sale and purchase agreement |
| Additional Buyer’s Stamp Duty | Depends on the buyer’s profile and existing properties | One flat rate on the whole price | Within 14 days of the sale and purchase agreement |
| Seller’s Stamp Duty | The seller, on a resale within four years | A rate that steps down with each year held | On the resale |
Summary of the IRAS rules on this site’s stamp duty page, read on 22 October 2026.
For an individual, the count of residential properties already owned is taken at the time of purchase, so a buyer who still owns a home when signing pays ABSD at the second-property rate unless a relief applies.
Timing, SSD and the Budget for Grand Dunman
Both BSD and any ABSD are payable within 14 days of the sale and purchase agreement, before the bank has lent anything, so the money for them has to be ready alongside the 5% booking fee. The progressive payment calculator builds the duty into the payment schedule.
SSD only arises on a sale within four years of buying. Where the purchase was made on or after 4 July 2025, the rate falls for each year the home has been held:
| Holding period at sale | SSD rate |
|---|---|
| Up to 1 year | 16% |
| More than 1 year, up to 2 years | 12% |
| More than 2 years, up to 3 years | 8% |
| More than 3 years, up to 4 years | 4% |
| More than 4 years | No SSD |

In the order of payments, the 5% booking fee comes first, then the 15% due with the sale and purchase agreement and the duty within 14 days of that agreement, and the bank’s loan only once the buyer’s own share is complete.
