Scope, checklist and when a purchase is pre-registration
The ninth edition dated 30 January 2026 applies to businesses registered on/after 1 July 2015. A purchase is pre-registration if the supplier issues its invoice or receives payment,whichever first,before your registration; delivery/performance alone does not settle the classification. Complete and retain the Pre-registration GST eligibility self-review checklist,including its calculator if useful; it is not routinely submitted to IRAS. Use the guide’s apportionment methods or obtain prior Comptroller approval explaining an alternative and its basis.
All six general conditions remain necessary
Goods/services must be supplied to you or imported by you,used for your business,supported by valid tax/simplified invoices or permits naming you as importer,and used for taxable supplies or out-of-scope supplies that would be taxable in Singapore. Regulations 26/27 must not block the input. Take reasonable steps to establish no Missing Trader Fraud arrangement and reach a conclusion a reasonable person would reach. Exempt/non-business use does not become claimable through a pre-registration concession. A source cross-reference says 4.2(c)for exempt supplies,although the substantive taxable-use test is 4.2(d); the substantive requirement is retained.
Goods: the six-month distinction and raw materials
Goods acquired within six months before registration can be claimed in full if still held—not sold,transferred or disposed—even if already used or leased. Apportion units no longer held. Goods acquired earlier can be fully claimed only if not consumed or supplied before registration; partial consumption/supply requires attribution. Raw materials used to manufacture finished goods qualify to the extent those finished goods remain unsold,regardless of when materials were acquired; track both production and onward movement. Partial-exempt businesses still restrict inputs to taxable activity.
Services, rental and utilities
Services must be acquired within six months and not directly attributable to pre-registration supplies for a full claim. Own-business office rental,utilities and phone costs are treated as not directly attributable if not onward supplied before registration. Services older than six months are disallowed. AnnexC separately says rental/utilities older than six months are unclaimable unless consumed or onward supplied after registration: do not omit this qualification or turn the services limit into a blanket prohibition for all rental/utilities. Directly attributable costs straddling registration require allocation.
Unit allocations: Examples 1–3
Example 1: three raw-material cartons with S$300 GST; one unused and two producing 20 finished units,10 sold before registration. Claim 1/3×300+2/3×10/20×300=S$200. Example 2: four photocopiers acquired within six months,eachS$350 GST; one sold,one gifted and two leased but still held. Claim 2/4×S$1,400=S$700. Example 3: three lubricant cartons acquired earlier withS$300 GST,two consumed; claim 1/3×300=S$100. The raw-material treatment follows surviving finished goods,while a within-six-month asset is tested for continued holding.
Older movable assets: Example 4
Use the shorter income-tax or accounting useful life. It starts at invoice/payment acquisition unless evidence proves later first use/lease; no adjustment solely because actual life later differs. Example 4: packaging machine acquired/used 1 November 2022,GST S$9,500,registration 1 August 2023. Accounting life 7 years versus tax 6 years selects 6;9 months already used leaves 5.25 years. Claim 5.25/6×9,500=S$8,312.50. Goods used beyond their whole life have no remaining-life amount under this method.
Older immovable property: Example 5
For land,buildings and integrated fixtures used before registration,claim purchase GST less AV/365×pre-registration-use days×GST rate;366 may be used in a leap year. Availability normally marks use,including a TOP,unless evidence proves later use. Example 5:2024 propertyS$4.375 million plusS$393,750 GST; available 1 January but renovation proven and leased only 15 April;registration 1 August. AV S$60,000,108 days at 9%,366-day basis: disallowedS$1,593.44,claimS$392,156.56. AV is an allocation proxy,not the purchase price.
Separately acquired fixtures: Example 6
Mounted cabinets,air-conditioners and partitions separately purchased can use a three-year life from first use; presume acquisition unless proven otherwise. Example 6: cabinets acquired 1 December 2022,GST S$350,registration 1 July 2023. Seven months used leaves the source’s rounded 2.42 years;2.42/3×350=S$282.33. Keep that published rounding when reproducing its amount rather than presenting the result as an unrounded exact-month computation.
Own occupied premises with no supplies: Examples 7–8
A concession allows full property GST if still held and used as the business’s premises but no supplies commenced before registration,subject to normal taxable-use rules. Example 7: propertyavailable 1 July 2022,staffoccupy 1 August,GST S$50,000,registration 1 July 2023 without supplies—fullS$50,000. It does not cover free third-party use. Example 8: related J uses H’s property free 15 January 2024 until H registers/occupies 1 August. AV S$60,000,GST S$393,750,199 days/366 at 9%disallowsS$2,936.07;claimS$390,813.93.
Onward rental and utilities: Example 9
Allocate the bill period directly attributable to pre-registration onward supplies. Example 9: Y registers 15 August 2023;15 JuneinvoiceGST S$700 covers 1 July–30 September 92 days;subletting starts 15 Julywith invoices on each 15 th. The 15 Julyinvoicecovers 15 July–14 August,31 days pre-registration. Claim(92−31)/92×700=S$464.13. Do not disallow every day before registration: the own-use portion not onward supplied benefits from the stated own-use treatment.
Service allocation proxies: Examples 10–12
Three publicised proxies are units/value of goods/services supplied; pre-registration service period over the total specific period; and pre-registration ongoing sales period over one year. Example 10 repairGST S$70 for two generators,one sold before registration,claimsS$35. Example 11 tenant-securing commissionGST S$700 for two-year 730-day rental beginning 15 June 2023,registration 1 July,16 days pre-registration:claim 700−16/730×700=S$684.66. Example 12 ongoing face-mask advertisingGST S$200 invoiced 15 February 2023,firstsales 1 March,registration 1 July,122 days:claim 243/365×200=S$133.15. The source retains 730 days for its two-year illustration and a 365-day advertising proxy; use these as published examples,not universal calendar-day mandates.
Progress/partial billings across six months: Example 13
For goods payments spanning the six-month boundary,IRAS allows full pre-registration tax if the goods are held at registration and have not been used/supplied more than six months beforehand. Presume use at availability/delivery/TOP unless proven otherwise. Example 13 completed property option/depositApril 2023,remainingpayment/transferJuly,registration 1 November 2023. Despite Aprilbeingoutside sixmonths,the property becomes available within sixmonths,so all option,deposit and balanceGST qualify subject to normal conditions.
Renovation/construction concessions: Examples 14–15
Renovation and construction normally include goods and services requiring different rules. A concession permits full tax if the completed or renovated property remains held and was not used or supplied more than six months before registration. Otherwise, renovation costs use a three-year life from use, presumed to start at completion unless proved otherwise; construction uses the immovable-property AV method. Example 14: renovation completed 1 April 2023, property leased 1 May, registration 1 August, GST S$1,400—full claim. Example 15: retail outlet completed and used 1 January 2023, registration 1 August, GST S$700; the source’s rounded remaining life of 2.42 years gives 2.42/3 × 700 = S$564.67. A different eventual lifespan does not require recalculation.
Post-registration billing for earlier delivery: Example 16
Goods/services billed or paid after registration are post-registration acquisitions even if delivered/performed earlier. A parallel administrative concession allows full claims for goods still held and rental/utilities/services not directly tied to earlier supplies. Goods no longer held and costs wholly attributable to pre-registration supplies are disallowed;straddling directly attributable costs are apportioned. Example 16 July 2023 own-business rentGST S$700 billed 5 August after 1 Augustregistration—fullclaim under the own-use concession,not an automatic right for every July expense.
All six FAQs and proving when property was used
An office bought four months before registration and leased three months before qualifies in full if still held. Own-operations rental and utilities are not directly attributable if not onward supplied. Disallowed direct-cost examples include valuation of an antique watch already sold, advertising a prior concert or expired product promotion, and cleaning a previously let exhibition hall. Non-direct examples include regulatory audit, HR training and own-building maintenance, subject to six-month and general conditions. Older vacant or renovating premises and non-car vehicles under repair can be unused if proved; warehouse storage, worker transport by pickup and third-party occupation, even free, constitute use. Raw-material and finished-stock tracking remains required. Starting supplies only after registration permits a full service claim if six-month and general conditions are met.
Documentation, return boxes and flowcharts
Keep the eligibility checklist, a service description/purchase/use-date list, and a stock account recording purchased quantities, production inputs, purchase dates and later disposal of original and produced quantities. Preserve tax invoices, import permits and payment evidence. Claim eligible pre-registration purchases in the first return: Box 5 for taxable purchase value and Box 7 for GST. Annex B’s goods path and Annex C’s rental/service path are explained above; Annex D consolidates unit, life, AV and service-period methods plus concessions. None removes the general conditions or turns nonclaimable GST into deductible input.
AnnexA: all six blocked-expense groups and medical exceptions
The six blocked groups are recreational/sporting club fees including transfer fees; staff medical costs; staff medical/accident insurance; benefits for staff family members; motor-car purchase/running costs unless outside the Regulation 25(1) definition; and betting, lotteries, sweepstakes, fruit machines and games of chance. Medical costs can qualify if obligatory under the Work Injury Compensation Act or a collective agreement. For treatment costs on or after 1 October 2021, work-nature or work-environment health-risk treatment can qualify under Singapore written law, or COVID-related treatment under a government/public-authority written advisory. The insurance exception remains WICA/collective agreement; it does not automatically receive the broader 2021 medical-treatment exception.
Source dates, rounding and amendments
Older examples retain their stipulated tax instead of recalculating at 9%. The 2024 property examples use 9% and 366 days, with published rounding retained. The amendment log includes the 2017 checklist, 2018 own-use/raw-material clarification, 2021 conditions/medical changes, 2022 motor-car updates and 2023/2024 rate changes. It ends January 2024 despite the 2026 ninth-edition cover. GST enquiries go through IRAS Contact Us.
