Singapore Registrar of Companies & ACRA Guide

Written by Ascentium Content Team | 17 August 2026

Every company registered in Singapore relies on the Singapore Registrar of Companies at different stages of its business journey. In Singapore, these responsibilities are carried out by the Accounting and Corporate Regulatory Authority (ACRA), which oversees business registration, corporate compliance and the maintenance of the official register of business entities.

Beyond incorporating new businesses, ACRA helps companies meet their ongoing statutory obligations, maintain accurate corporate records and keep business information up to date throughout their lifecycle. Understanding its role can help business owners navigate Singapore's regulatory framework more effectively while ensuring their companies remain compliant.

In this guide, we will explain the role of the Singapore Registrar of Companies, the business registration process, key compliance requirements and how ACRA supports businesses at every stage of their journey.

 

What is the Singapore Registrar of Companies?

The Singapore Registrar of Companies is the official authority responsible for administering company registration and maintaining the country's register of business entities. In Singapore, this role is performed by the Accounting and Corporate Regulatory Authority (ACRA), a statutory board under the Ministry of Finance that oversees business registration, corporate regulation and the maintenance of official company records.

As the national business registrar, ACRA plays a central role throughout a company's lifecycle, from incorporation and maintaining corporate records to processing statutory filings and business information updates. Most of these services are provided through BizFile+, ACRA's online filing portal, making it easier for businesses to fulfil their regulatory obligations and access essential corporate services.

As Singapore's Registrar of Companies, ACRA plays a central role in maintaining a transparent, well-regulated and business-friendly corporate environment. Beyond registering companies, it oversees key regulatory functions that help businesses operate in compliance with Singapore's corporate laws.
