Scope and property classification
The eighth-edition guide dated 30 January 2026 covers developers owning the land on which property is built, sales and construction input-tax recovery. Completed property means TOP obtained; property without TOP remains under development for this guide. Non-residential sale/lease is taxable, residential sale/lease exempt, and mixed-use property is split according to approved use. Separate property-owner guidance addresses leasing in detail. An invoice includes a payment bill such as a debit note, not only a formal tax invoice.
What counts as residential property
Residential includes vacant land zoned Residential and approved for residential/condominium development; government/relevant-authority supplied vacant land or existing buildings required to be demolished when approved exclusively for residential/condominium development; and buildings used or intended principally for residential purposes, subject to the stated government-demolition exception. Other properties are non-residential. For land with a building/structure, use the building’s approved use during the supply period, not land zoning alone, supported by URA permissions or HDB/SLA/JTC letters.
Registration and associated taxable supplies
Include non-residential sale prices and rental proceeds with other taxable business supplies when assessing registration; exempt residential proceeds do not enter that taxable total. Furniture/fittings sold or leased with a residential property are separately taxable and enter the registration assessment. Estate management, maintenance fees, service charges and sinking funds are taxable even for residential buildings. Once registered, account for taxable output tax and report residential supplies as exempt. The fact that the underlying home is exempt does not exempt every associated service.
Completed sales: four triggers for the balance
Option fees and exercise deposits trigger GST at the earlier of payment receipt or invoice issue. For remaining completed-property proceeds, use the earliest of payment, invoice, legal-title transfer or making the property available to the buyer for occupation. Any payment-billing invoice can trigger supply, including debit notes. Sales orders, pro-forma invoices, account statements and claim letters/statements generally do not trigger it where normal practice does not treat them as bills for payment.
Progressive payments and occupation
For property under development, each progressive payment is taxed at the earlier of its receipt or invoice. TOP usually precedes availability for occupation; the building can only be occupied after TOP or CSC. When made available or transferred, the remaining sale balance is taxed under the earliest four-trigger rule even if unpaid. Maintain payment schedules, invoices and title/occupation events so final proceeds are not postponed until cash collection.
Reimbursements and counter-supplies to contractors
Recoveries from the main contractor for clerk-of-works overtime, borrowed workers or site utilities are the developer’s supplies and attract GST. Bulk-purchased cement/steel supplied to the contractor is a separate counter-supply: issue tax invoices and charge GST on its value. Do not simply deduct materials from progressive construction billings for GST purposes; contractor construction and developer materials are distinct supplies even if settled by net payment.
Defect rectification versus compensation
If a defaulting main contractor’s repair is instead commissioned by the developer and recovered/deducted from the contractor, the developer supplies rectification and charges GST. If the buyer commissions repairs and deducts from the developer, and the developer deducts from the contractor, each onward rectification supply is assessed separately; Example 1(b)’s registered buyer and developer both charge GST at their stages. Mere compensation to the buyer for defects without actual work by that buyer does not attract GST in Example 1(c). The contractual repair obligation and actual work distinguish a supply from compensation.
Maintenance funds and unsold units
Before management corporation formation, a registered developer accounts GST on maintenance charges paid by sold-unit purchasers and on charges it bears for its own unsold units. Transferring the remaining maintenance-fund cash to the corporation afterward does not attract GST again because tax was already accounted. Input tax on unsold non-residential units’ maintenance and agents’ marketing fees may be recovered where directly attributable to taxable supplies made/to be made and normal recovery conditions hold.
Reverse charge and imported low-value goods
From 2020, a registered developer or GST group without full input recovery applies reverse charge on imported services, such as overseas architectural work for residential/mixed projects. Account output tax as supplier and claim corresponding input tax only to the extent normal recovery allows. From 2023, reverse-charge LVG purchases include local/overseas suppliers, marketplaces and redeliverers regardless of their registration, excluding those directly attributable to taxable supplies. Fluctuating exempt supplies may justify electing service reverse charge at longer-period end. An unregistered business importing/expecting more than S$1 million of relevant services and LVG in 12 months without full recovery may face registration under the reverse-charge rules.
Land purchases and conversion relief
Non-residential land/development used for business, business leasing or sale/lease can support input recovery including purchase, conveyancing, construction and professional fees, subject to taxable-use and normal conditions. Residential development normally cannot recover input tax, but land acquisition has exceptional regulation 41(1) relief described in a separate guide. Converting a non-residential building to residential without demolition has regulation 41(2) relief only for land cost. These limited land rules do not make residential construction generally recoverable.
Repayment of previously claimed input tax
Where a non-residential building previously supported an input claim and is demolished for residential development following Residential rezoning, the guide says that previously allowed input tax need not be repaid. If the existing building is merely converted to residential use instead, previously claimed input tax must be repaid. Distinguish the old claim adjustment from the separate limited acquisition/land-cost relief; demolition and retention have different outcomes.
Direct attribution before residual allocation
Separate mixed-development purchases into non-residential construction, residential construction and common costs. The first category is fully recoverable under normal conditions, the second not recoverable, and the third is residual input tax requiring apportionment. If the quantity surveyor can identify every cost item and allocate it to the ultimate taxable/exempt supply, there is no residual pool and no residual formula. Typical shared costs include site clearance, site offices, mixed-building driveway/piling, architect/surveyor fees, show units and marketing overheads.
LBC formula during development
Recoverable residual tax equals residual tax multiplied by non-residential GFA × its LBC rate divided by the sum of that amount and residential GFA × its rate. Include every distinct use group where more than two components have different rates, and allocate common areas between uses. LBC replaced DC, Differential Premium and Temporary Development Levy from 1 August 2022. For periods ending before that date use operative DC rates; periods ending on/after it use LBC rates operative at the accounting period-end. Rates update on 1 March and 1 September; the July–September 2022 example uses 1 September LBC rates. Round the recovery percentage to the nearest whole number.
After TOP: construction and overheads diverge
Remaining contractor/professional construction billings continue using LBC after TOP; joint developments may use the entire project GFA. Common administrative/marketing overheads switch to taxable supplies divided by total supplies starting in the TOP accounting period; where multiple TOPs are issued, the source permits applying that ratio after all TOPs are obtained. Total supplies include standard-rated, zero-rated and exempt supplies. Exclude received supplies under customer accounting and imported services/LVG subject to reverse charge from numerator and denominator. Regulation 33 exempt additions and incidental-exempt exclusions require the relevant regulation 34/35 conditions; ordinary residential sales usually exceed regulation 35 limits.
Approved floor area and multiple projects
Use the latest URA-approved GFA. A new written permission during the accounting period determines that period’s GFA; later changes do not require retrospective reworking of already claimed amounts under the concession. Aggregate buildings within one development. For multiple developments, use each project’s own GFA for residual costs attributable to it; only business-wide residual costs not attributable to a particular project may use aggregated GFA. Keep project attribution rather than applying one convenient percentage indiscriminately.
Carparks and the S$1.6 million example
Where approved GFA omits parking, allocate construction by lots. Office/shop-reserved lots support taxable recovery; resident-reserved lots do not; unreserved lots form common costs subject to LBC. Example 2 has 200 lots: 40 office-reserved, 60 unreserved and 100 resident-reserved. On S$1.6 million construction at 9%, directly recoverable office GST is S$28,800 (1.6m × 40/200 × 9%). Residual GST is S$43,200 (1.6m × 60/200 × 9%) for LBC apportionment; residential-reserved costs are not recovered. Although the example describes Basement 1 as common, it separately computes the 40 reserved-lot direct portion.
No deferral when the post-TOP ratio is zero
After TOP, a period with no taxable supplies can recover only inputs directly related to non-residential property under the usual conditions. The common administrative/marketing ratio is zero, so no residual claim arises for that period. Those residual claims cannot simply be deferred to the next accounting period. The longer-period adjustment is the prescribed later reconciliation; it is different from choosing to postpone a quarterly claim until a better sales mix appears.
Longer-period adjustments and tax-year cycles
Before TOP, changes in LBC rates/GFA do not require longer-period reworking under the concession. After TOP, reconcile common administrative/marketing residual tax using the whole longer-period supply ratio and adjust over/underclaims in the first return afterward. The first longer period starts at the beginning of the TOP accounting period and ends at tax-year end; later periods follow tax years. Jan–Mar quarterly filers use April–March, Feb–Apr filers May–April, and Mar–May filers June–May. Construction remains under LBC rather than the overhead adjustment formula.
Annex A: all use groups and rate changes
The 10-storey example has sector 113, hotel GFA 4,500m² (group C), shops/offices 5,500m² (A), residential 8,500m² (B2), total 18,500m². March 2022 DC rates are hotel 5,320, shops/offices 9,450, residential 6,650; September illustrative LBC rates are 5,250, 9,850 and 6,720. Weighted non-residential value over total value gives 57% for the first-half illustration and 58% for the second. March-quarter input directly taxable S$600,000 plus 57% of residual S$50,000 gives S$628,500 recovery; exempt-direct S$400,000 is excluded. September-quarter taxable input S$800,000 plus 58% of S$15,000 gives S$808,700; exempt-direct S$500,000 is excluded. The September rates are explicitly illustrative, not a current sector-rate table.
Annex B: quarterly amounts after TOP
TOP is 15 August 2022; the first longer period is July 2022–March 2023. June before TOP has taxable supplies S$250,000, construction residual S$20,000 recovered at 57% = S$11,400 and overhead residual S$5,000 at 57% = S$2,850. After TOP, September has taxable zero/exempt S$650,000, construction residual S$15,000 at 58% = S$8,700 and overhead S$3,500 at 0% = zero. December has taxable S$400,000/exempt S$800,000, overhead S$7,000 at rounded 33% = S$2,310. March has taxable S$550,000/exempt S$750,000, construction S$25,000 at 60% = S$15,000 and overhead S$4,500 at rounded 42% = S$1,890.
Annex B: the S$300 adjustment
The longer period totals taxable supplies S$950,000 and exempt S$2.2 million, total S$3.15 million. The rounded ratio is 30%. On overhead residual S$3,500+S$7,000+S$4,500=S$15,000, allowable recovery is S$4,500. Actual provisional quarterly overhead claims are S$0+S$2,310+S$1,890=S$4,200, so add S$300 in the June 2023 return. Construction recovery S$23,700 stays separate, and the printed overall provisional total S$27,900 matches S$23,700+S$4,200. The source table places S$4,500 in the overhead total column although it labels the row provisional; that figure is the longer-period allowance, not the sum already claimed.
Deregistration, history and enquiries
Where input tax was allowed/claimed on purchased non-residential property retained at deregistration, deem a supply at open-market value using the prevailing GST rate and account for it in final GST F8. The edition history covers supply-time/definition and registration refinements in 2018, reverse charge in 2019, LBC and LVG changes in 2022, and 2023/2024 GST-rate changes to the carpark example. The January 2026 cover date has no separate substantive entry in the amendment table. Questions go to the GST Division via IRAS Contact Us.
