Estimate stamp duty, GST, loan and the cash you need to complete a purchase at ARC 380.
A strata office at ARC 380 is bought with cash and a bank loan. There is no Additional Buyer’s Stamp Duty and no Seller’s Stamp Duty, Buyer’s Stamp Duty runs on the non-residential scale, and GST at 9% applies where the seller is GST-registered. GST is never financed, so it has to be budgeted as cash alongside the deposit and the duty. The calculator below puts those pieces together across the ten weeks from option to completion.
ARC 380 obtained TOP in 2018 and holds its CSC, so a purchase here is of a finished, titled unit. The balance of the price falls due on completion of the sale rather than in construction instalments.
Figures update as you type.
90% is generally offered to an operating company taking the unit for its own use. Investment purchases are usually capped nearer 80%.

GST is charged on each instalment as it falls due, not once at the end.
Your own funds only. Anything the bank draws down is excluded.
This is upfront cost only. The construction instalments below are drawn down by your bank as each stage completes, with the GST on each one payable in cash.

Once the loan is fully drawn.
During construction you pay interest only on what has been drawn so far, so the amount climbs stage by stage — see the two right-hand columns above.
Payable from TOP onwards. Nothing is levied during construction.
Non-residential property is taxed at a flat 10% of Annual Value. IRAS sets the Annual Value from market rents for comparable units — the rent figures here are your own estimate, not an assessment.
Same price, tenure and rate; only the loan differs.
Buyer’s Stamp Duty is assessed on the price before GST, on the non-residential scale: 1% on the first $180,000, 2% on the next $180,000, 3% on the next $640,000, 4% on the next $500,000, and 5% on the balance above $1.5 million. It is a marginal scale, so each rate applies only to the slice of the price falling inside its band. On the $2,100,000 default that comes to $74,600 — an effective rate of about 3.6%, well under the 5% headline. The ARC 380 stamp duty calculator sets the same figure out band by band.
GST at 9% is charged by a GST-registered seller on the purchase price, and is shown against each payment as it falls due because the time of supply follows the seller’s tax invoices. Across the whole purchase it comes to 9% of the price — $189,000 at the default — and none of it is covered by the loan.
Loan-to-value on commercial property is set by bank credit policy rather than by a statutory ceiling, and it turns on use. Where the purchasing business will occupy the unit itself, 90% is generally offered to an operating company. Where the unit is bought to let, the ceiling is usually nearer 80%. Tenure is commonly available to 25 or 30 years, and ARC 380’s freehold title means there is no remaining-lease constraint shortening either the tenure or the quantum, at purchase or at refinancing.
TDSR applies where the borrower is an individual, including a sole proprietor or someone incorporating a company purely to hold the unit. An operating company is assessed on its own financials instead. CPF cannot be used for commercial property, so the deposit, the stamp duty and the GST are all cash. Every figure here is indicative — confirm with your bank before committing.
Whether the GST is recoverable as input tax cannot be determined from the outside — it turns on the buying entity, not simply on whether it is GST-registered. The general guideline is that an operating company, one that is GST-registered and already carrying on taxable business activities, may claim the GST as input tax as it is incurred. A non-operating company — newly incorporated, or an investment-holding vehicle not yet carrying on taxable activities — would not usually be able to claim at that point, and claims may instead begin once taxable activities commence, such as letting the unit or operating the business from the premises. These are guidelines only, and every case is subject to the rules set by IRAS.
IRAS taxes non-residential property at a flat 10% of Annual Value, and assesses that Annual Value from market rents for comparable space rather than from what you actually receive. The estimate in the calculator is driven by the rent and unit size you enter, so put your own figures in rather than relying on the defaults. The rate is the same whether the unit is let or occupied by your own business.
The output is an indicative estimate for budgeting, not a quotation. Confirm stamp duty with IRAS, loan terms with your bank, and the deposit structure and completion date against the actual Option to Purchase. To match a figure to a specific unit, review the current pricing and recent transactions, cross-reference the floor plans, and speak with our sales team.
No. ARC 380 is zoned commercial, so no Additional Buyer’s Stamp Duty applies at purchase and no Seller’s Stamp Duty applies when you sell, whatever the holding period. Buyer’s Stamp Duty still applies, on the non-residential scale that tops out at 5%.
GST at 9% is charged where the seller is GST-registered, which is normal for a sale by a company. It sits on top of the purchase price and is not financed — a bank lends against the price, not against the GST — so it has to be budgeted as cash. On the $2,100,000 default that is $189,000 across the purchase.
Loan-to-value is set by the bank rather than by a statutory ceiling, and it turns on use: 90% is generally offered to an operating company taking the unit for its own occupation, and around 80% where it is bought as an investment. CPF cannot be used for commercial property, so the deposit, stamp duty and GST all have to come from cash.
