Frequently Asked Questions (FAQ)
1. What does an accounting service provider in Singapore do?
An accounting service provider in Singapore manages your company’s financial records, files taxes, prepares financial statements, and ensures you comply with ACRA and IRAS rules. Most providers also handle payroll, GST submissions, and corporate secretarial duties. This means you get a full finance team, without hiring one in-house. For Singapore SMEs, outsourcing to a professional accounting firm is one of the most cost-effective ways to stay compliant and keep your books accurate year-round.
2. Do I have to hire an accounting firm in Singapore?
No, hiring an external accounting firm is not legally required in Singapore. However, every Singapore-incorporated company is legally required to keep proper accounting records, prepare financial statements, and file them with ACRA each year under the Companies Act. You can do this in-house if you have the expertise.
That said, most business owners choose to outsource. Singapore’s accounting rules are complex, they include SFRS (Singapore Financial Reporting Standards), IRAS tax filing, GST submissions, and ACRA XBRL filing (a structured digital format for financial reports). Getting any of these wrong can result in fines or penalties. Hiring a professional accounting firm is strongly recommended, even if it is not compulsory.
3. What is the difference between an accounting firm and a corporate secretarial firm in Singapore?
An accounting firm handles your financial records, tax, and bookkeeping. A corporate secretarial firm handles statutory compliance, such as filing annual returns, maintaining company registers, and organising AGMs (Annual General Meetings).
Under Singapore law, every company must appoint a qualified corporate secretary within six months of incorporation. Some accounting providers, like OneStop Professional Services, offer both services together, which saves time and avoids gaps between your accounts and compliance records.
4. Can a foreign company use a Singapore accounting service provider?
Yes. Foreign companies and entrepreneurs often use a Singapore-based accounting service provider to comply with local regulations. ACRA requires all Singapore-incorporated companies to have a locally resident director and a qualified company secretary. Most accounting firms in Singapore also assist with company incorporation, Employment Pass applications, and nominee director services for foreign founders. Firms like OneStop Professional Services have experience helping overseas entrepreneurs set up and manage their Singapore operations.
5. What is InvoiceNow and how does it affect my accounting in 2026?
InvoiceNow is Singapore’s national e-invoicing framework, which requires businesses to send and receive invoices digitally through the Peppol network. It’s a secure, standardised system used internationally. From 2026, newly GST-registered businesses must use InvoiceNow-compliant accounting software to issue invoices to government agencies and other connected businesses.
This means your accounting system must be InvoiceNow-ready. If your current provider or software does not support this, you risk delays and compliance issues. Choose an accounting service provider who uses IRAS-approved, InvoiceNow-compatible tools, such as Xero to stay fully compliant.
