Accounting and finance in Singapore operates within a structured regulatory framework — ACRA (Accounting and Corporate Regulatory Authority) governs Singapore-incorporated companies, IRAS (Inland Revenue Authority of Singapore) administers tax, and ISCA (Institute of Singapore Chartered Accountants) is the national accounting body issuing the CA Singapore designation. Understanding the Singapore-specific credentials, tax framework (notably GST at 9%), and the ACRA filing environment is essential for accounting professionals targeting Singapore roles.

Singapore tax framework — what accountants need to know
- GST (Goods and Services Tax): 9% from 1 January 2024. Mandatory registration for businesses with taxable turnover exceeding S$1 million per year. GST compliance, filing, and advisory is a significant accounting sub-specialisation.
- Corporate income tax: Singapore's flat rate is 17% — with partial tax exemption for first S$300,000 of chargeable income and startup exemptions.
- IRAS (Inland Revenue Authority of Singapore): Tax authority — myTax Portal for all Singapore tax filing.
- ACRA and iXBRL: Singapore-incorporated companies must file financial statements in iXBRL format for most regulated companies. iXBRL tagging is now a practical skill for corporate accountants.
