When the financial year ends, every business — whether a local SME or a growing cross-border company — must prepare accurate and complete year-end tax reports.
In both Australia and Singapore, failing to report the right information can result in:
❌ Missed tax deductions
❌ Penalties from ATO or IRAS
❌ Delays in tax return processing
❌ Unhappy auditors
Here’s a detailed checklist of what to include in your year-end tax reports — and common mistakes to avoid.
1. Income Statements
Your tax report must include:
✅ Sales and service income
✅ Interest and investment income
✅ Other income (grants, foreign exchange gains, etc.)
Australia: Report via BAS and Company Tax Return (Form C).
Singapore: Declare in Form C or Form C-S to IRAS.
Common Mistake: Not reconciling sales with bank deposits → triggering ATO or IRAS review.
2. GST / BAS / GST F5 Reporting
Australia:
✅ Final BAS lodgement for the financial year → ensure correct GST on sales and purchases.
Singapore:
✅ Final GST F5 return → report GST collected and input tax claims accurately.
Extra Tip: Many SMEs miss the Reverse Charge rule — both ATO and IRAS enforce this strongly now.

3. Payroll Reporting & Finalisation
Australia:
✅ Finalise STP reporting via accounting/payroll software.
✅ Income statements must be ready for employees in myGov.
Singapore:
✅ Prepare and submit IR8A and Appendix 8A (benefits), Appendix 8B (share options), IR8S (employer CPF contributions), if applicable.
Common Mistake: Reporting employee allowances incorrectly — can trigger audit queries.

4. Superannuation (Australia Only)
✅ Ensure all SG contributions are paid before the deadline (to claim deduction).
✅ Include SG payments in employee payroll summaries.
Common Mistake: Not paying SG for eligible contractors → ATO treats them as employees for super.
5. Expense Records and Documentation
✅ Record and justify all business expenses:
- Operating expenses (utilities, rent, marketing, software)
- Depreciation (capital assets)
- Loan interest
- Travel and motor vehicle costs
- Insurance premiums
- Professional services (legal, accounting)
Documentation Required: Invoices, bank statements, contracts, receipts.
Common Mistake: Claiming GST on non-creditable expenses → IRAS or ATO will adjust this.
6. Inventory Valuation
✅ Perform a stocktake as at year-end.
- Record quantity and value of stock on hand
- Adjust for obsolete, damaged, or slow-moving stock
- Use cost or net realisable value, whichever is lower
Common Mistake: Inflating inventory value → artificially boosts reported profit.
7. Profit & Loss (P&L) Statement
✅ Complete and accurate P&L is essential:
- Gross revenue
- Cost of goods sold (COGS)
- Operating expenses
- Net profit/loss
P&L summary must reconcile with GST and income tax reporting.

8. Balance Sheet (Statement of Financial Position)
✅ Required for tax and compliance purposes:
- Assets (cash, inventory, receivables, fixed assets)
- Liabilities (payables, loans, accrued expenses)
- Equity
Tip: Review debt ageing → old debts may need to be written off for tax deduction.
9. Company Tax Return Preparation
✅ Australia → Form C with ATO (due by standard lodgement dates)
✅ Singapore → Form C or C-S with IRAS (November or December, depending on e-filing)
Prepare:
- Tax computation schedules
- Detailed expense listings
- Related party transaction disclosures
- Foreign income disclosures (if applicable)
10. Common Mistakes in Year-End Tax Reporting
❌ Omitting income from foreign sales
❌ Incorrect GST claims
❌ Unsubstantiated expense claims
❌ Failing to finalise payroll reporting
❌ Not adjusting inventory correctly
❌ Using outdated asset depreciation schedules
👉 Professional review of your year-end package can save thousands in penalties or disallowed deductions.
