Mistakes are a common part of the tax filing process, given the complexity of tax forms. If you’ve already filed your tax return but later discover errors, you can rectify these by submitting a T1 Adjustment Request. The Canada Revenue Agency (CRA) permits adjustments to tax returns for up to 10 years after the initial filing. 

The Process of Filing a T1 Adjustment Request 

Filing a T1 Adjustment Request is generally straightforward. The T1 ADJ form is available on the CRA website and is divided into four sections, A to D. In Section A, you’ll need to provide personal identification details like your name, Social Insurance Number (SIN), address, and the tax year you’re adjusting. Section C is where you detail the adjustments, including the line number, the original amount, the proposed change, and the adjusted amount. You must also give a comprehensive explanation for each change. Section D is for certifying the accuracy and completeness of the information provided. 

After submitting your request, the CRA will review it, which can take anywhere from 2 to 8 weeks or more. Following their review, you’ll receive a notice of reassessment and a letter explaining the CRA’s decision. If you disagree with their assessment, you have the option to file a Notice of Objection.
