How do I access what charitable donation receipts I used in previous tax returns and which ones I haven't used and can be carried over to future returns?

If you need to know if you have claimed donations in previous years, you can find out using the CRA My Account online service. Once you log into your account, click on the tax returns tab at the top of the page. From there, you can view your tax returns from previous years. Look at line 349 on your previous T1 General tax return prior to 2019 or line 34900 of your Income Tax and Benefit returns of 2019 and onward to determine whether you have claimed donations for each of the past five years.
