What It Does
This module turns your posted invoices and bills into a complete, ready-to-file IRAS GST F5 return. It aggregates standard-rated supplies (the 9% rate effective 1 January 2024), zero-rated and exempt supplies, taxable purchases and imports, computes the output tax due and the input tax and refunds claimed, applies reverse charge on imported services and bad-debt / pre-registration reliefs, and arrives at the net GST payable to or refundable from IRAS — then reconciles the result against the general ledger and exports it in the IRAS GST F5 box layout.
Complete F5 Box Structure
Boxes 1–8 for supplies, purchases and the net GST, plus supplementary boxes 9, 11, 12 and 13 for scheme imports, total revenue, reverse-charge services and OVR supplies.
Reverse Charge & OVR
GST on imported services subject to customer accounting is added to both output (box 6) and input (box 7), netting to zero for a fully-taxable person, exactly as IRAS requires.
UEN / GST No. Validation
Real Singapore GST registration number validation on the company and partners — ROB, ROC, other UEN and legacy M-series formats, with a check-letter self-consistency guard.
Monthly / Quarterly / Half-yearly
Automatic prescribed accounting periods with the statutory due date — one month after the end of the accounting period.
GL Reconciliation
Compares the computed return to the GST booked on the tax accounts, with a rate sanity check on standard supplies, flagging discrepancies before filing.
IRAS-ready Export
A deterministic GST F5 submission file (one line per box, in IRAS field order) for archiving or keying into myTax Portal, plus a formatted Excel workbook in SGD.
Draft to Paid Workflow
Every accounting period is tracked through Draft → Computed → Filed → Paid, with full chatter logging. Bad-debt relief and pre-registration input tax entered on the return flow into box 7, and any net credit is shown as refundable from IRAS.
Requirements
- Odoo 18.0 or 19.0 (Community or Enterprise).
- The Python library
xlsxwriterfor the Excel export (standard with most Odoo deployments). The IRAS submission file needs no external library. - Works on top of the standard Odoo Accounting application.
Disclosure
This module reads only your own Odoo accounting data and contacts no external service. The 9% standard rate reflects the IRAS rate effective 1 January 2024 and is configurable per company.
