Correct a personal income-tax return
How do I correct a personal income-tax return after filing?
Wait for your notice of assessment before requesting a correction to a personal income-tax return. CRA’s Change my return, ReFILE and mailed routes have different conditions; use the route that supports your situation.
Where to begin
- Wait for the assessment and identify the tax year and correction.
- Check whether Change my return or ReFILE through certified software supports your circumstances.
- Use the mailed instructions where needed and retain supporting records.
- Keep the confirmation and await CRA’s response before sending another change to a request already underway.
Before you open the official service
- Notice of assessment, tax year and records supporting the correction.
Keep your actual documents and account details off this website. Use the official service’s current checklist before applying.
What to check for your situation
This does not update bank details or correct every kind of business return. The official page uses conditional instructions; not all routes apply to every return.
Fees, processing times and document rules can change. This page helps you navigate; it does not confirm eligibility or replace the government’s instructions.
