The statutory instalment schedule for a GATE+ unit, the eight-week option period, and where GST lands.
GATE+ is a development under construction, with an estimated Temporary Occupation Permit of 30 January 2029. Payment follows the schedule set by the Sale of Commercial Properties Act: 20% falls due across an eight-week option period, then the balance is drawn in instalments as each construction milestone is certified. The schedule governs what the buyer owes the developer at each point; how much of it the buyer funds and how much a bank disburses is a separate question, covered on the GATE+ industrial loan page.
Two features of this schedule matter more than the percentages. The first is that 20% is due before construction money starts moving at all, which makes the option period the heaviest cash moment in the whole purchase. The second is that GST at 9% accrues on each instalment as it falls due and is payable in cash throughout. The GATE+ purchase calculator models both against a specific quantum.

Timelines are indicative and set by certified construction progress, not by calendar dates. The confirmed GATE+ schedule is the one set out in the Sale & Purchase Agreement.
| When | Milestone | Amount |
|---|---|---|
| On receiving the Option to Purchase | Option fee, by cheque or cashier’s order | 5% + GST |
| +2 weeks | Sale & Purchase Agreement issued to the solicitor — the bank’s letter of offer should be signed by this point | — |
| +3 weeks | Exercise the Sale & Purchase Agreement — it must be exercised within three weeks of receipt. Buyer’s Stamp Duty is payable to IRAS within 14 days, plus the legal fee | Duty + legal |
| +3 weeks | Completion of sale — balance of the 20% | 15% + GST |
Where an option is not exercised, the customary split is 2.5% forfeited as a cancellation penalty and 2.5% refundable — confirm the exact terms in the Option to Purchase itself. Duty bands are set out on the GATE+ stamp duty and GST page.
GST at 9% is charged on each instalment as it falls due to the developer. It is not deferred to completion and it is not part of the loan — banks fund the instalment, not the tax on it. Across the whole purchase it comes to 9% of the price, and it lands in instalments spread over the build.
That matters for cash planning at two moments in particular: the option period, where GST on the full 20% is payable within eight weeks, and the Temporary Occupation Permit stage, where a single 25% instalment carries the largest GST charge of the programme. Whether any of it can be recovered as input tax turns on the purchasing entity — the guidelines are set out on the stamp duty and GST page, and the position should be put to IRAS or a tax adviser.
The 5% booking fee falls due on the grant of the Option to Purchase, with GST payable on it at the same time, by cheque or cashier's order. The balance of the 20% follows at completion of the sale, about eight weeks later.
Seven, after the 20% due during the option period: 10% at foundation, 10% at reinforced concrete framework, then five stages of 5% each, followed by 25% at Temporary Occupation Permit and a final 10% on completion.
On every instalment, as it falls due. GST at 9% accrues stage by stage across the whole programme and is payable in cash, because banks do not finance it. Over the purchase it totals 9% of the price.
Rates and thresholds are those published by IRAS and the Monetary Authority of Singapore and were verified on 15 September 2026. They are provided as general information and should be confirmed with IRAS, MAS or a bank before commitment.
