Yes, you can make changes to a filed tax return by filing an adjustment. The Canada Revenue Service (CRA), requires that you wait until you’ve received your Notice of Assessment (NOA) before filing an adjustment. In many cases, the CRA will catch the mismatch and automatically adjust your return for you.
How you file your adjustment depends on how your original tax return was filed, and whether it was a federal or Québec return. Instructions on filing adjustments for both scenarios are provided below:
If you filed your original tax return using CRA’s NETFILE service:
- Sign in to your online TurboTax account or launch your edition of TurboTax CD/download for the tax year you want to prepare an adjustment for.
- In Return Manager, select the ReFILE button beside the filed tax return you want to adjust.
If you printed and mailed your original tax return or are in a situation excluded from ReFILE:
- See the CRA’s How to change your return page for how to make an adjustment online in your CRA My Account or by mail.
Note: Online editions of TurboTax don’t currently support ReFILE of federal tax returns for residents of Québec.
TurboTax doesn’t currently support Revenu Québec’s electronic Déclaration amendée service.
To make an adjustment to a Québec return, see Revenu Quebec’s Changing an income tax return that you have already filed page for instructions on how to make an adjustment online in your Revenu Québec My Account, or by mail.
