What to consider for your next decision
Changes to tax administration can affect how you prepare records, access an account or authorize a representative. The official release determines the scope and effective date; your circumstances still need individual review.
- Read the official source and check the date the change takes effect.
- Confirm which accounts, returns or authorizations apply to you.
- Use your secure workspace for documents; never share CRA credentials.
