The sixteen-page guide covers GST-registered developers, main contractors and specialist subcontractors. Local construction, alteration, repairs, maintenance and demolition are taxable for both residential and non-residential properties. Residential-sale exemptions do not automatically exempt contractors’ works.
Local and overseas construction examples
Progress-billed factory work and site/foundation subcontractors charge GST when registered. A Singapore developer’s Beijing hotel project is different: directly overseas-land services can zero-rate under 21(3)(e); goods already abroad/not brought here can be out-of-scope, or goods exported from Singapore zero-rated where conditions apply. Customer incorporation alone does not determine location.
Progress and retention payment timing
GST is due at the earlier of payment or invoice, including a payment-demand debit note; if paid first, invoice within thirty days. Retention separately follows earlier receipt/invoice for that sum. A provisional letter of claim before architect certification is not a tax invoice because final amount is not settled. Keep the work certificate and agreed invoice; reductions use credit notes and increases additional invoices.
Gross supplies cannot be replaced with net settlement
Where contract includes materials and work, a main contractor selling materials to the subcontractor and subcontractor supplying finished work are two supplies, each invoiced gross. Example 4A bricks S$8,000 and complete walls S$15,000 require both full invoices, not GST only on S$7,000 difference. In 4B the subcontract is work-only S$7,000, so only that service is supplied.
Three types of deposits
Payment for tender plans/specifications/quantities is a document sale and taxable. An advance offsetting future work payments is taxable. A genuine security for performing the contract is not consideration for a supply. Example 5 taxes S$25 tender documents and the contractor’s working advance, but not the five-percent bank-guarantee security returned after completion.
Suspension compensation and damages
Payment solely compensating lost income/costs from suspended work is not taxable; payment for completed work before suspension is. Breach/delay damages can be compensatory: S$3,000 per calendar day late-completion damages is not GST. Settlement for an actual supply is taxable despite being court-ordered or out-of-court.
Defect example 7: rectification versus compensation
For a S$1.2 million contract with S$150,000 retention, developer’s S$100,000 third-party rectification charged back is a separate taxable supply to contractor. Original full S$1.2 million remains taxable whether rectification is netted against retention or recovered through proceedings/settlement. If developer does no rectification but obtains compensation for poor work, that compensation has no supply/GST; the original full contract supply remains.
Reimbursement and agent disbursement
Buying in your own name/invoiced to you is principal procurement: recovery is taxable even without markup and even if original seller unregistered. Example 8 buys S$1,000 materials from an unregistered seller but charges GST on onward recovery; its S$70 tax is a retained historical seven-percent illustration, not the later rate. Example 9 BCA permit registered to developer and paid merely as agent is disbursement without GST on recovery.
Dormitory rent, services and input recovery
Bare workers’ dormitory premises rent is exempt; furniture/fittings, meals, laundry, cleaning, security/common maintenance and principal reimbursements are taxable. Split a bundled rent reasonably, for example furnishings cost plus reasonable markup. Direct exempt input is not recoverable; common input is residual and apportioned under partial exemption, as shown by shared factory/dormitory fire insurance. The dormitory section was added July 2024.
