If you are selling a condo early in Singapore in 2027, check Seller’s Stamp Duty (SSD) before agreeing on the sale date. For residential property acquired on or after 4 July 2025, IRAS publishes a four-year holding period with rates of 16%, 12%, 8% and 4% across the successive years. Earlier purchases can fall under a different schedule.
Find the acquisition and disposal dates that IRAS recognises, then apply the relevant rate to the higher of the selling price and market value at disposal. Ask your conveyancing lawyer to verify the dates and treatment if the property was acquired in stages, through a transfer or under unusual terms. Compare the likely duty with the cost and practical consequences of waiting.
- Check which schedule applies from the acquisition date.
- Use IRAS’s acquisition and disposal dates, especially near an anniversary.
- Apply the relevant rate to the correct value base.
- Keep duty, loan redemption and net cash proceeds separate.
- Compare a confirmed sale now with a realistic later sale and holding costs.

Start with the date on which the interest in the property was acquired. IRAS sets out different schedules for different periods. Its July 2025 change increased the holding period from three years to four and raised the applicable rates for purchases on or after 4 July 2025. A seller disposing of a property in 2027 should use the schedule that applies to the acquisition, rather than selecting a schedule simply because the property is being sold in 2027.
Compare two purchases a few days apart
Two owners might have bought similar condos near the July 2025 change. If one acquired the property on 3 July and another on 4 July, they can face different schedules even if both sell on the same later date. Check which document determines the acquisition and verify its execution details. If the case falls outside the two date ranges in the table, consult IRAS’s full schedule and check whether SSD is relevant.
The rate table expresses a rate for the entire applicable value base at the relevant holding period, subject to the rules. This differs from a progressive tax where portions of a value are taxed in separate bands. Identify the correct holding period and then apply the rate once to the applicable base. Check the special treatment where different portions of the interest were acquired on different dates.
Record which interest is being sold
Confirm whether the proposed transaction disposes of the whole property or part of an interest. Where ownership has changed since the original purchase, the earliest date in the household’s records may not tell the whole story. Ask the lawyer to check the documents for the person and interest being transferred. Keep the conclusion alongside the proposed sale so the household can revise it if the structure changes.
Give the working calculation a date and source. A screenshot of a rate table is useful only if you can identify what acquisition dates it applies to. Save the latest IRAS guidance and record any assumptions. This makes it easier to compare a sale at a different time without accidentally switching to the wrong schedule.
| Acquisition date | Up to 1 year | Over 1 to 2 years | Over 2 to 3 years | Over 3 to 4 years | After 4 years |
|---|---|---|---|---|---|
| 11 March 2017 to 3 July 2025 | 12% | 8% | 4% | No SSD under this schedule | No SSD under this schedule |
| On or after 4 July 2025 | 16% | 12% | 8% | 4% | No SSD under this schedule |
A condo transaction has several dates. These can include option grant, acceptance, agreement, completion, possession and the day you move in. IRAS provides definitions and specific rules for establishing the acquisition and disposal dates. Ask the conveyancing lawyer to identify the controlling documents for your case. The relevant date can be earlier than completion or key handover.
Identify the acquisition event
For an ordinary purchase, check the executed instrument through which you accepted or agreed to acquire the property. For an uncompleted condo, do not assume that the date of TOP, completion of the building or key collection starts the SSD holding period. Use the acquisition rule that actually applies. If different interests were acquired at different times, record those events separately.
Ask for a copy of any document missing from your file. A payment receipt or calendar entry can help you locate the transaction but may not establish the relevant legal date. If you relied on an option, confirm when it was accepted under the rules. Save the answer with the instrument instead of retaining only a date typed into a spreadsheet.
Identify the sale event before granting an option
Ask the lawyer how the contemplated sale will be treated and what action by the buyer establishes disposal. A buyer may pay for an option on one day and exercise it on another. If the sale is close to a holding-period boundary, get advice on the actual dates and terms before granting or agreeing to anything that depends on a different rate.
Make the timeline clear to the people handling the transaction. Separate your preferred marketing date from the first date on which the intended disposal would fall into a later period. An anniversary may look straightforward in a spreadsheet and still require careful reading of which day starts or ends a tier. Obtain a transaction-specific date rather than planning a close boundary from a rounded count of years.
Read the instrument and its conditions, not just the date at the top
IRAS’s general definitions refer to acceptance of the Option to Purchase, the Sale and Purchase Agreement or transfer where the earlier events do not apply. IRAS also distinguishes an option that is subject to execution of the Sale and Purchase Agreement. Have the lawyer identify how the actual instrument is treated. A document can show a signature date without answering whether that signature was the event that determined the holding period.
For example, an owner may have paid for an option in one month and signed the purchase agreement in the next. When the property is later sold, a calendar that starts from the first payment could put the anticipated disposal in a different tier. The owner can prevent this by making a dated note of the acquisition event verified by the lawyer and by asking the same question about the planned disposal. Recheck when a buyer proposes a different timetable.
When the intended date sits close to a tier boundary, ask the lawyer to confirm the treatment of a sale on either side. Keep the planned exercise window and any restrictions clearly documented. A few days can make a material difference, and the legal terms are more useful than adding years to an approximate month in the household’s notes.

IRAS says SSD is calculated on the higher of the selling price and market value of the property as at disposal. A lower agreed price therefore does not necessarily reduce the duty base to the price on the agreement. Where the disposal involves part of an interest, check the rules for valuing that interest and identifying the portion subject to duty.
Worked calculation at one rate
Suppose a property is sold for $1.30 million and its applicable market value is $1.35 million. If the confirmed rate for the example is 8%, applying it to $1.35 million gives $108,000. Applying the same rate to the selling price would give $104,000 and understate the duty in this example. The numbers are invented. Use current IRAS guidance and confirm the valuation basis and rate for the actual case.
The duty is one of several items that affect what remains from a sale. Obtain a current mortgage redemption estimate, confirm any applicable CPF housing refund and allow for relevant legal and other expenses. Use the actual amounts and dates rather than assuming the price less the loan balance gives the money the household can spend.
Keep settlement and payment separate
Ask when SSD must be stamped and paid under the applicable rules and which party or professional will handle it. IRAS’s residential SSD guidance states that it must be paid within 14 days from the executed sale contract under the usual rule. Verify the relevant signing event and current instructions with your lawyer. Make sure the payment can be funded when due, especially if completion or the release of proceeds is later.
Build a short worksheet with the sale price, market value used, rate and duty. Add the loan, CPF and costs separately. Record the amount of money the household expects to be able to use and when. A verified net amount after completion is useful, and the schedule tells you whether another source is needed before completion.

A household selling early may be trying to buy another home, move for work or respond to a change in family needs. Start with the earliest date you must move, the amount you need for the next arrangement and the cash you can already access. If the sale is meant to fund a deposit or duty elsewhere, check when the sale proceeds are available. Keep the two transactions on the same calendar.
Compare the funding with and without a later tier
Assume the sale in a worked comparison would incur $108,000 of duty in one scenario and $54,000 in another because it falls under a later 4% tier at the same base. The difference is $54,000. The household should also calculate the mortgage interest, maintenance, property tax and any other costs of holding during the additional period. Compare the cost of continuing to live there or paying for another address, and use plausible sale prices for both dates.
Distinguish a cash-flow cost from an economic cost. A monthly mortgage payment can include both interest and principal, while the eventual redemption amount may decline. For cash planning, show the full payment on its due date. For a cost comparison, avoid counting both the same principal payments and the same amount of outstanding principal as new expenses. Ask your lender or adviser for the figures needed to compare accurately.
Identify what an earlier sale would solve
An earlier sale could release money for a move, avoid management burdens or fit a job or care deadline. Record those benefits alongside the duty. Waiting can save an amount of tax under the appropriate schedule, while requiring the household to keep paying for the property and accept uncertainty about when it will sell. Give each route a realistic scenario instead of comparing a definite offer now with an assumed offer later.
If the replacement home has its own acquisition duty or other conditions, keep them on separate lines. SSD on the home being sold and any duty on the purchase are different obligations. The fact that they arrive in one move makes it more important to verify both.
Build three separate snapshots of the same transaction
The first snapshot covers the day the sale contract is executed. Identify the duty and other payments that follow from it and the funds you will use. The second covers legal completion. Add the price balance, loan redemption and relevant adjustments, and check when the cash residue becomes accessible. The third covers the move. List the first payment for the next address, overlap and the minimum usable reserve.
These snapshots catch a common timing problem. A household can expect a positive result after completion and still have insufficient cash when the tax is due. It may also be able to pay the duty and complete the sale but have less available for the next address than hoped. Review the three stages in order and identify the smallest balance. Verify with the relevant professionals when amounts are due and which sums count toward the same obligation.
Keep a conservative alternative alongside the preferred budget. It can use a lower sale price, a later release or extra time in temporary accommodation. Change only one assumption at first. Then combine the realistic adverse cases if the decisions depend on them occurring together. This gives the household a clearer sense of which funding or timing change would make an earlier sale viable.

A family has an offer for an illustrative $1.2 million sale. Its lawyer estimates that the sale at the intended date falls into an 8% tier, assuming the duty base is also $1.2 million. The example produces $96,000 of SSD. If the family waits until a confirmed later date and the same price and value still apply, a 4% rate in the example would produce $48,000. That is a $48,000 gross duty difference.
Add the holding costs and a different sale price
Assume it would cost another $15,000 to hold the property until the later date after accounting for relevant expenses. The simplified advantage of waiting falls to $33,000 before a change in sale price or other terms. If the market value and sale price later differ, the duty calculation may need to be updated as well. The point is to isolate the assumptions that produce the advantage, rather than to predict what the market will do.
Try a scenario where the later price is lower, a buyer takes longer to proceed, or the family needs another place to stay during the waiting period. Ask which scenario would change the decision. A household with a firm work move may decide that an earlier sale is worth the cost. Another may have enough flexibility to wait for the next tier and reassess.
Put the new decision date before the actual deadline
If waiting is preferred, mark when the family will begin marketing, when it will review the evidence and which dates the lawyer must check before a sale is agreed. Record the minimum acceptable sale proceeds and the maximum period the family can continue carrying the home. Keep both figures current as the circumstances change.
If the family takes the current offer, it can still use the same sheet to plan payment and the move. Check who will handle stamping, when the duty is due, and what documents support the later completion proceeds. The best decision record makes clear what the household received in return for selling earlier and what it would have had to fund to wait.
Estimate how much of a later price change the saving could absorb
In the example, after allowing for $15,000 of holding costs, the simplified saving from waiting is $33,000 at an unchanged price. Suppose the later selling price and market value both fall by $25,000, and the later duty is still 4%. The lower sale price reduces proceeds by $25,000, but applying the lower rate to the smaller base also saves $1,000. The simplified advantage would fall to about $9,000 before other changes. These figures illustrate sensitivity and do not forecast a later sale.
If the market value used for duty does not fall by the same amount, the result will differ. Make that explicit in the worksheet. A confirmed earlier offer and a possible later offer do not carry the same certainty, even when the arithmetic suggests a narrow difference. A family can choose the earlier offer for timing and certainty, or wait if it can fund the holding period and tolerate the market risk.
Give the waiting decision a review date before the later tier begins. Update the available offers, comparable sales and holding costs then. Keep the legal date confirmed separately. If the decision has already been made to wait, a review can still improve how the home is marketed and how the next move is funded.

IRAS describes rules and exemptions for particular kinds of transfer or disposal. A gift, a partial interest, a property acquired in stages or a transaction linked to legal orders may raise a different question from a straightforward condo sale. Use the actual documents and obtain advice on the statutory treatment before assuming a particular exemption or date applies.
Check sale restrictions separately from stamp duty
Some homes or ownership arrangements may have restrictions that affect whether and when a sale is permitted. SSD asks whether a duty is payable under the relevant tax rules. It does not establish permission to sell under every other rule. Verify both where they are relevant. The same applies to an agreement with a lender or another party that could affect settlement or the timing of a move.
Give a professional enough information to answer
Prepare the purchase documents, details of later changes in ownership, the proposed sale terms and the dates you think matter. Ask whether the interest being sold falls under one or more acquisition dates, which date establishes the sale and whether any special provision applies. Ask separately about the estimated duty, payment deadline and how it will be handled.
If the household is comparing several possible dates, request the treatment for each one. An answer about a single date can be accurate and still leave the next period unclear. Keep the conclusion and its assumptions with the worksheet. This makes it easier to act if a buyer proposes a different exercise or completion date.
Update the figures after a change
If the price, valuation or sale date changes, update the relevant line rather than carrying forward the original estimate. Then check the cash schedule again. An updated estimate can show whether the original plan still works, what funds must be ready sooner and whether the move timetable should change. Where timing is close to a boundary, verify the new position before acting.
Check the consequences of a partial sale
When an owner plans to dispose of only part of a residential interest, ask the lawyer to identify the exact portion and its acquisition date. IRAS describes applying the relevant base to the interest being disposed of. If portions were acquired at different times, ask how each is treated. Keep the calculation distinct from an estimate for selling the entire home, since those two transactions may have different values and dates.

Does every condo sale in 2027 have a four-year holding period?
Check the acquisition date. IRAS’s four-year schedule applies to residential acquisitions on or after 4 July 2025. Earlier acquisitions can fall under a different schedule.
Does my holding period begin when I receive the condo keys?
Use the acquisition date under IRAS’s rules for the actual transaction. Key collection and acquisition can occur on different dates. Check with the conveyancing lawyer if the property was uncompleted when purchased or the ownership changed later.
Is duty based on my profit?
IRAS applies the relevant rate to the higher of selling price and market value at disposal, subject to the applicable rules. The difference between your purchase price and sale price is a separate calculation.
Can I compare selling now with waiting solely on duty?
Add realistic holding expenses, the uncertainty of a later sale, and the effect on your move and funds. Verify the actual date and amount of any later rate change.
What should I confirm before agreeing on the sale?
- The exact interest and IRAS acquisition and disposal dates.
- The applicable holding-period schedule and value base.
- Duty amount, deadline and verified payment arrangements.
- Net sale proceeds and the dates they become available.
- The cost and practical effect of a later sale.
Review the calculation with current IRAS guidance and the transaction documents. Give the household time to make the sale decision before a legal or payment deadline takes away choices.
