Seller's Stamp Duty: when selling early costs you

What Seller's Stamp Duty is

Seller's Stamp Duty (SSD) is a tax paid by the seller when a residential property is sold within a defined holding period of when it was bought. Its purpose is to discourage rapid, speculative buying and selling. It is separate from Buyer's Stamp Duty and Additional Buyer's Stamp Duty, which the buyer pays - SSD is a cost to the person selling.

How the holding period works

SSD turns on how long you have held the property:

• The holding period is counted from the date you bought the property.
• If you sell within that period, SSD is payable.
• The rate generally tapers - higher if you sell very soon after buying, lower as you approach the end of the holding period.
• Once you have held the property beyond the holding period, SSD no longer applies.

The exact length of the holding period and the rates have been adjusted by the authorities over time. Confirm the current SSD holding period and rates with IRAS - this is the figure that decides whether selling early is affordable.

Who SSD catches

SSD most often affects:

• Sub-sellers. Someone selling a new launch before completion is, by definition, selling within the holding period - so SSD frequently applies. Our guide on sub-sales covers this.
• Owners whose plans change. A job move, a family change or a financial shift can force a sale sooner than planned, straight into the SSD window.
• Anyone treating property as a short-term trade. That is precisely the behaviour SSD is designed to discourage.

Why it matters when you plan a sale

SSD can be a substantial sum, because it is charged on the sale price. If you might need to sell within a few years of buying, SSD should be in your plan from the start - not discovered at the point of sale. Knowing where you are in the holding period tells you whether selling now carries an SSD cost, and how large it is.

Planning around it

You cannot make SSD disappear if you genuinely need to sell within the holding period - and you should not try to disguise a sale to avoid it. What you can do is plan: understand your holding period when you buy, avoid building a plan that depends on selling early, and if a sale within the window is unavoidable, get the SSD quantified by IRAS so the number is in your decision.

The honest summary

Seller's Stamp Duty is a tapering tax on selling a residential property within a holding period of buying it, paid by the seller. It most often catches sub-sellers and owners whose circumstances change. Confirm the current holding period and rates with IRAS, factor SSD into any plan that might involve selling within a few years, and never structure a sale to disguise it.
