The CRA doesn't automatically know what they are missing; generally, the Notice of Assessment is pushed out based on what you sent in and then from October 2023 - April 2024 the CRA will match what you submitted vs. the T-slips they received. That's how the CRA knew I missed a T5 slip from 2021.I tried to see if I could add a t5008 to my 2001 return as a test, but it only allows for adding t3 and t5. There's also no place to amend the schedule 3 information where I would normally enter the t5008 information.
Does the CRA automatically know that they are missing? Do they reference what it provided to them to my return? Luckily, I had no capital gains.
I see I can amend line 13200, the total capital gain/loss. But it doesn't even show line 13199, the proceeds of disposition. If I changed only 13200, and not 13199, it wouldn't make sense.
T1 Adjustment Request (canada.ca)
This is the paper version of the Adjustment Request, which you would mail to your Tax Centre along with any supporting documentation.
You reference the Line you need to change; and the original amount of the line; the amount you are adding or subtracting; and the new amount.
So, the Lines you need to change (potentially) would be the following:
- Line 12000 (Amount of Dividends Eligible and Other than Eligible)
- Line 12100 (Interest and Other Investment Income)
- Line 13000 (Other Income)
- Line 19900 (Taxable Capital Gains or Net Capital Loss in 2022)
