You can swap your business to a dormant company. Just let IRAS and ACRA know. A dormant company is a business that’s not receiving any form of income or is actively trading. The filing requirements for a dorman company is less stringent.
If you maintain a dormant company, you can recommence at any point. Just let IRAS know within 1 month of resuming your business.
Otherwise, if you have no intention of keeping the company or restarting it in future, you can wind up your business. Sell your assets and settle your debts, and then you can move on.
