Why a Tax Checklist Matters for Singapore Businesses

Tax season in Singapore involves multiple obligations, from Corporate Income Tax filings with IRAS to annual returns with ACRA. Missing deadlines or overlooking requirements can result in penalties and unnecessary disruptions.

A tax checklist acts as a roadmap—ensuring that important tasks are not just completed, but done correctly and on time.

Singapore Tax Checklist for the Busy Season

Here’s a practical checklist to keep your business tax-ready:

1. Review Financial Records

Ensure that all income, expenses, and supporting documents are recorded accurately. Good bookkeeping now avoids last-minute stress later.

2. Confirm GST Compliance

If your business is GST-registered, prepare for your quarterly GST e-Filing and ensure all transactions are correctly classified.

3. Prepare Estimated Chargeable Income (ECI)

Submit your ECI within 3 months from the financial year end, unless you qualify for an exemption.

4. Get Ready for Form C-S/C Filing

For most companies, Form C-S or Form C must be filed by 30 November each year. Ensure that your tax computations and supporting schedules are complete.

5. Check for Tax Incentives or Rebates

Leverage available tax exemptions, rebates, or incentives for SMEs to optimise your tax position.
