Complete Guide to Singapore Corporate Accounting Services: Pricing, IRAS/ACRA Compliance, and Seamless Migration
What are corporate accounting services in Singapore?
Corporate accounting services in Singapore encompass full-scope financial management tailored to local statutory requirements. This includes routine bookkeeping, preparing financial statements under Singapore Financial Reporting Standards (SFRS), submitting Estimated Chargeable Income (ECI) and Form C-S/C to the Inland Revenue Authority of Singapore (IRAS), managing Goods and Services Tax (GST) returns, and filing Annual Returns with the Accounting and Corporate Regulatory Authority (ACRA). Professional providers leverage cloud platforms like Xero to maintain real-time compliance starting from S$60/month.
1. Quick Overview: Pricing & Plans
All packages include access to smart receipt submission via WhatsApp/digital upload, secure document storage, and dedicated support from ISCA-certified accounting specialists.
Plan | Effective Transaction Rate | Core Scope & Deliverables | Suited For |
Annual Filing & Bookkeeping, Accounting | S$4/transaction | • Annual / Monthly / Weekly bookkeeping & management reports, & quarterly review meetings • 24-hour Support SLA | Early-stage startups, holding companies, and low-volume businesses Active SMEs needing ongoing visibility on margins and cash flow Fast-growing companies with active ops, invoicing, and staff |
2. Who Needs Outsourced Accounting in Singapore?
Startups & Newly Incorporated Entities
Singapore entities must establish compliant ledger structures immediately upon incorporation. Engaging a professional service ensures proper tracking from day one, avoiding deadline panics for early filings like ECI.
Foreign Founders & Remote Directors
Offshore business owners managing a Singapore Private Limited company must submit local tax filings and comply with Singapore Financial Reporting Standards (SFRS). Outsourced accounting allows non-resident directors to maintain 100% remote compliance without maintaining physical finance operations in Singapore.
Growing SMEs Replacing Manual Spreadsheets
As monthly transaction volumes expand, manual tracking introduces reconciliation errors. Outsource partners introduce automated bank feeds, structured Profit & Loss statements, Balance Sheets, and Cash Flow statements for clear operational decisions.
Founders Seeking Time Recovery
Managing receipts, GST calculations, and tax schedules in-house drains core operational focus. Outsourcing delivers an assigned accounting team at a fraction of the cost of an in-house finance department.
