How to authorize your accountant with the CRA (and why it matters)

Giving The Tax Mates representative access lets us see your slips, answer CRA letters and fix problems fast. Here's how authorization works.

The single most useful thing you can do after hiring an accountant takes about five minutes: authorize them as your representative with the Canada Revenue Agency.

Why it matters

  • We see your slips — T4s, T5s, RRSP receipts — directly from the CRA, so nothing gets missed.
  • We see your RRSP room and carry-forwards, so your planning uses real numbers.
  • We can answer CRA letters and speak to the CRA for you, instead of you waiting on hold.
  • Problems get fixed faster — reassessments, missing slips, benefit questions.

How to authorize us (individuals)

  1. Sign in to CRA My Account.
  2. Go to your profile and find the section for authorized representatives.
  3. Choose to add a representative and enter the identifier we give you (our business number or RepID).
  4. Pick the level of access — we'll tell you which one we need — and the tax years.
  5. Submit. Then let us know, and we'll confirm on our side.
We'll send you our identifier and the exact access level when you sign on. Never share your own CRA password — authorization is the secure way to give access.

For businesses

Business owners authorize representatives through My Business Account or Represent a Client, for the specific program accounts — payroll, GST/HST or corporate income tax — you want us to manage.

Can I remove access later?

Yes. You can cancel or change a representative's access at any time from your CRA account.
