When Is a Tax Clearance Confirmation Required?

This confirmation serves as the basis for the company to complete the dissolution dossier with the Department of Planning and Investment or other relevant regulatory bodies.

In the case of a capital transfer or full acquisition of a company, the transferee typically requires a tax clearance confirmation to ensure there are no outstanding tax liabilities from prior periods.
