Historical transition and decision factors
Version 21 May 2024 supplements the detailed 2024 rate-change guide. GST moved 7%→8% on 1 January 2023 and 8%→9% on 1 January 2024. Invoice/payment time and when goods were delivered/services performed determine transition treatment, not the rate on upstream purchases.2023 payment for an agreed specific supply requires 8%; a supplier cannot choose 9% merely because the later invoice date is 2024. Old-rate elections for 2023 performance are optional, for any/all qualifying transactions, with adequate evidence.
Trade-ins, card payments and warranty
Trade-in is two supplies: after change,9% on old equipment sale and full new-equipment price, not net cash difference. A course paid fully by bank/card in December 2023 is 8% despite 2024 delivery and customer instalments to bank. Concession treats full card charge in 2023 as pre-change receipt even if merchant settlement is 2024. Contractual one-for-one warranty replacement, even a new model and credit/reinvoice, retains 8% for the 2023 original sale.
Staged payment, property and banquets
Exhibition 30% invoiced with 20% paid in 2023:20% remains 8%, unpaid 10% needs 8% credit and 9% invoice by 15 January 2024; unbilled 70% is 9%, or one 80% replacement invoice by that date. Property option 1% paid December 2023 is 8%, later balance/property availability 9%. Brokerage completed 2023 with no further service can elect 8% even if purchase/completion/commission settlement later. Banquet fully prepaid 2023 is 8%; deposit 8% and 2024 balance 9%, communicated clearly.
Construction certification and retentions
A letter of claim is not a payment invoice.2023 completed work certified/invoiced/paid 2024 defaults 9%, with 8% election for pre-change performance. A 5% retention for 31 December 2023 completion paid November 2024 follows the same option. Straddling work requires reasonable proxy or architect valuation to split 2023/2024 retention; absent tracking,9%. Defect rectification under original contract does not change retention’s relation to 2023 work; separately charged services beyond contract follow their own performance date.
Hire purchase, gifts and security deposits
A 20% down payment billed/paid November 2023 remains 8%;2024 balance invoice/payment is 9%, with 8% election if goods delivered December 2023. Gift over S$200 bought 2023 and given 2024 attracts 9% deemed output; if purchase input not claimed, no deemed output. Genuine lease security deposit is not payment at collection; applying it to February 2024 rent when invoiced/offset 2024 triggers 9%, while returned unused deposit has no corresponding GST.
Imports, hotel nights and consignment
Imports from 1 January 2024 are 9% regardless of 2023 supplier invoice. A valid 8% December import permit may clear delayed goods in 2024 but requires a short-payment permit for 1% shortfall. Hotel 31 December 2023–2 January 2024 billed/paid checkout defaults 9%; daily/nightly convention allows 8% for 31 Decembernight,9% for 1 Januarynight. Consignment invoiced/paid 2024 defaults 9% but goods drawn for consumption December 2023 can elect 8%.
Extra fees and two-rate-change exception
Extra S$20 correcting a 2023 S$100 fee in January 2024 defaults 9%, but fully 2023 performed service permits 8%.15 Januaryadjustment limit addresses old 8% invoices that should become 9%, not ordinary fee corrections. Services completed September 2022 yet first billed/paid March 2024 cannot elect 7% under ordinary transition rules; Comptroller’s exception under guide 6.6.3–6.6.8 can allow it with conditions and evidence. No advance approval is needed for that eligible election; records must be available.
Advance tax invoices and rentals
Before 1 January 2024 a tax invoice cannot show 9%; use 8% then required credits/reinvoicing. For straddling advance services, adjust the lower of remaining payment and remaining post-change service value, or cancel/reissue. Rental 5 December 2023–4 January 2024 not paid before change is split 27/31 at 8% and 4/31 at 9%; correct January portion by 15 January. Inform customers of potential adjustment. Software services can use reflective man-hours/days; seek clarification if apportionment difficult.
Credit notes and mixed-rate invoices
Returns years later and 2023 volume rebates use original supply rate, including 7% original goods returned 2024. An 8% election on S$1,000 previously billed 9% can credit S$10 tax difference or cancel and reissue S$1,080. Post-change invoices can show both 8%/9% clearly; a qualifying 8% invoice can be issued even after 15 January 2024. These permissions do not allow 9% on pre-change tax invoices.
Price displays and GST absorption
Old 8% brochures can be stamped with a 9% price-adjustment statement; unrecallable distributed brochures require prominent signs.2023 orders/proformas should show 8% inclusive price plus potential-change notice, or both prices with 9% effective only 2024. Absorbing extra tax does not remove required 9% credit/reinvoice for a registered customer. The government-rebate example shows 100 value+9 GST−1 rebate=108 payable; input 9 can be claimed subject to normal conditions because agency accounts 9, with compliant invoice.
Evidence, reverse charge and concessions
Keep customer acceptance, time sheets, cost statements or engineer/quantity-surveyor work certificates as appropriate. Reverse-charge 8% election needs service-completion evidence plus internal election/accounting records. Recurring January 2024 GIRO can count as pre-change only if successfully deducted by month-end, relating to pre-change bills and normal billing cycle. Cheques must be banked by 4 January 2024 and clear successfully; failing concession requires cancellation/reinvoice 9%.
Excess advance credit and bad debts
Payments must concern a specific supply accepted by both parties. In quarterly maintenance, December 2023 payment for invoiced January–March 2024 is 8%; extra April–Decemberamount merely held as general customer credit is not yet specific consideration, and later quarter invoice or credit offset triggers 9%. Bad-debt relief follows the original tax invoice and normal qualifying conditions, not a substitute new rate.
GST returns and customer accounting
Different-rate purchases/sales and adjustments go into the same return, summed in proper boxes with listings/evidence.12 January 2024 credit/new invoice for November 2023 invoice goes in January–March 2024 F 5. Customer accounting changes who accounts output, not transition rates. Example 21,600 at 8% with 2024 delivery/payment must become 21,800 at 9% by 15 January and customer reports the adjustment in that period. Footnote scope: local prescribed phones, memory cards/off-the-shelf software to registered business customer over S$10,000 exclusive.
