The commercial rate scale at Smart Food @ Mandai
Five bands apply: 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 everything above $1,500,000. The scale is marginal, not a cliff edge — crossing into a band does not re-rate the amount below it, which is why the effective rate always sits below the headline 5%. At the indicative entry price of $2,502,000 the duty works out at $94,700, an effective rate of about 3.8%.
Buyer’s Stamp Duty is payable within 14 days of the document being executed, and is assessed on the purchase price or the market value of the unit, whichever is higher.
The Seller’s Stamp Duty position at Smart Food @ Mandai
Industrial property carries Seller’s Stamp Duty on a disposal within three years of purchase: 15% in the first year, 10% in the second, 5% in the third, and nothing after that. It is charged on the higher of the selling price or the market value at the date of sale, and it is the seller’s liability, not the buyer’s. It is worth factoring into the holding plan at the point of purchase, because on a freehold asset the three-year window is short relative to the intended hold.
GST on a Smart Food @ Mandai purchase
GST at 9% applies to the purchase price. On a building under construction it falls due instalment by instalment as each stage is billed, rather than in one payment at the start. A GST-registered operating company using the unit in its business can generally claim the GST as input tax, making it a timing cost; a non-operating holding entity or an unregistered buyer will usually carry it as a real one. Recovery depends on registration status, the use of the unit and the conditions for claiming input tax — subject to the rules set by IRAS.
What this Smart Food @ Mandai calculator does not cover
Legal and conveyancing fees, valuation fees, bank charges and mortgage duty, and lease duty arising on a subsequent letting of the unit. Nor does it settle the assessed amount: where IRAS considers the market value to exceed the stated price, duty is charged on the higher of the two.
