How we help you comply with GST
You can engage us for the different services:
▸Periodic internal reviews on your GST accounting, based on the IRAS ASK review kit
We review your GST processes against IRAS's Assisted Self-help Kit (ASK) — a structured self-assessment of your GST controls, practices and past F5 returns. We surface errors early so you can correct them (often under IRAS's Voluntary Disclosure Programme for reduced penalties), and it keeps you eligible for GST schemes that require an ASK review.
▸Close your GST accounting period
At each period-end we reconcile your output and input tax, tie your GST balances back to the general ledger, resolve any mismatches, and lock the period — so your GST F5 is accurate and your books are clean before filing.
▸GST accounting services
End-to-end GST bookkeeping, handled for you:
- Record sales & purchases with the correct tax codes (SR, ZR, ES, OP, TX…)
- Track output tax on sales and claimable input tax on purchases
- Maintain valid tax invoices and records to IRAS standards
- Reconcile your GST control accounts to the ledger every period
- Prepare your quarterly GST F5 return, ready for review & submission
▸Implement Artificial Intelligence and technology to check your sales and purchase records
We deploy AI tools that scan your sales and purchase records for red flags — wrong or missing tax codes, GST mismatches, duplicate entries and arithmetic errors — before they reach your GST return. Faster and more consistent than manual review, with a clear audit trail.
▸Provide a GST-compliant accounting app
We set you up on a GST-compliant accounting app that captures the right tax codes, keeps IRAS-standard records, and generates your GST F5 figures automatically — so compliance is built into your daily workflow, not bolted on at quarter-end.
▸Prepare your GST figures and submit to IRAS, based on your in-house records
Prefer to keep bookkeeping in-house? Send us your records and we'll prepare your GST F5 figures, review them for errors, and submit your return to IRAS via the myTax Portal on your behalf — on time, every period.
▸GST de-registration
Winding down, restructuring, or below the S$1M threshold? We handle GST de-registration end-to-end — eligibility check, the cancellation application to IRAS, your final GST F5, and accounting for assets held at the point of de-registration.
▸Apply for GST exemption schemes
We assess which GST schemes your business qualifies for — such as the Major Exporter Scheme (MES) or Import GST Deferment Scheme (IGDS) that ease import-GST cash flow — and manage the application and the ASK review these schemes require.
Do I need to register?
▸Mandatory — your taxable turnover exceeded S$1 million in the past 12 months, or is expected to exceed S$1 million in the next 12 months.
▸You must register within 30 days of becoming liable.
▸Voluntary — you can register below S$1M to claim input GST. We'll advise if it's worthwhile for you.
