Your marital status can affect your taxes and any benefit and credit payments for which you’re eligible. Let the CRA know about your new marital status by the end of the following month after the status change. Some exceptions apply:
- If you’ve separated, let 90 consecutive days pass before notifying the CRA.
- If you’ve become widowed, provide the CRA with the deceased's date of death as soon as possible.
To avoid issues with NETFILE, wait until after you’ve notified the CRA before doing your taxes. Remember that the marital status on your tax return is based on your status at the end of that tax year.
