You must keep the personal tax information on your profile.
If you want to be paid as a business / entity / personal real estate corporation (PREC), you must enter your personal information (SIN, CRA Tax ID) and Business Entity Tax IDs (BN and CRA BN Tax ID).
If the business entity tax information is filled out correctly, reZEN will pay you through your business entity (not personal). You do not need to delete / edit the personal information.
