If I submit an adjustment request form, what do I include with it?

If I submit an adjustment request form, what do I include with it?

To request an adjustment by mail, send one of the following plus any supporting documents (T-slips, receipts, schedules, etc.) to your tax centre:
  • a completed Form T1-ADJ, T1 Adjustment Request, or
  • a letter providing all the details, including your social insurance number, address, a telephone number where CRA can reach you during the day, and the taxation years you want them to adjust.

It will take longer for the CRA to process your request if you send a letter instead of Form T1-ADJ.

For more information, visit the CRA website.
