New T2050 and T4063
December 2008 marks the release of the new Form T2050, Application to Register a Charity Under the Income Tax Act, and its companion Guide T4063, Registering a Charity for Income Tax Purposes. Form T2050 was revised in accordance with legislative amendments and to improve the form’s general ease of use. Guide T4063 was revised to put need-to-know information about the advantages, requirements, and obligations of registered charities front and centre, in order to facilitate the process of applying for charitable registration under the Income Tax Act.
