Executive Rule No. 56 outlines the mandatory procedure for an Incorporated Body to secure a Tax Clearance Certificate from the Tax Department. This Rule stipulates that the entity must formally request the certificate via an official letter. The issuance of the certificate is conditional upon the Incorporated Body having fully settled all outstanding taxes, as detailed in the final assessment letter. Furthermore, all due penalties pertaining to the specific taxable period for which the certificate is requested must also be completely paid beforehand.
