The CRA ReFile service allows you to send online adjustments for income tax and benefits returns using certified Netfile software and Efile software. You or your tax service provider can send adjustments for 2018, 2017, 2016, and 2015.
Advantages of ReFile:
You must use ReFile with the same certified Netfile software that you used to file your income tax and benefit return. If you filed a paper copy of your return then you will need to mail a paper form T1-ADJ - T1Adjustment Request to the CRA.
You Cannot Use ReFile when:
You cannot use ReFile to make changes to personal information you need to use MyAccount to make the following changes:
The ReFile system only allows you to make nine adjustments per year. If you go over that then you will get an automated response saying the limit has been reached and you will then have to file a paper request.
