What are tax receipts for?
Your tax receipt acts as proof of your gift when you file your income taxes. Gifts you make to registered charities act as a tax credit and reduce the amount of tax you pay. Giving's a good thing for many different reasons!
Note that if you file your taxes electronically, Canada Revenue Agency suggests you keep your tax receipts for five years. That's easy to do with CHIMP because your tax receipts are always available in your account.
