How do I change the company's business activity (SSIC code)?

Choose the new SSIC code and file it via ACRA BizFile — usually effective immediately and without a shareholders' resolution. A company's principal business is registered at incorporation using the Singapore Standard Industrial Classification (SSIC) code, with up to two principal activities. When the actual business changes, update the SSIC so ACRA's records match reality. The process: select the code from ACRA's SSIC list that best fits the new business, file the change of business activity via BizFile — generally effective immediately and without a shareholders' resolution. Note that some industries are regulated activities (e.g. finance, education, food & beverage, travel), and changing or adding to those SSIC codes may trigger additional licensing or approval requirements. A business scope that does not match actual operations can affect banking, tax and licensing compliance, so update the SSIC whenever the business pivots.
