When You Must Deregister
You must deregister for corporate tax when your business ceases trading, is dissolved, or is liquidated. Deregistration is a legal obligation under Article 52 of the corporate-tax law, not a choice, and the application must be filed within 3 months of the cessation or liquidation date. It applies to companies and to natural persons who stop a taxable business activity.
