Change Your Marital Status with the CRA: Dates and Steps

You should change your marital status with the CRA when your circumstances meet its rules, rather than waiting until your next tax return. The CRA uses family details to calculate benefits and credits. Therefore, the right start date matters as much as choosing the right status. A wedding date, a common-law start date and a separation date are not interchangeable.

When do you need to tell the CRA?

The CRA says to report a change by the end of the month following the month it occurs. For example, a marriage in March should be reported by the end of April. Keep a note of the actual event date before opening the update service. Do not use the day you complete the online form as the date your status changed.

Separation has an important qualification. The CRA's guidance refers to a separation lasting more than 90 days because of a relationship breakdown. A temporary absence for work or study is a different situation. If your case is unclear, check the CRA's explanation before entering a date that could change family benefits.

Prepare the details before signing in

• Your current and previous marital status.
• The date the change took effect under CRA rules.
• Your partner's identifying details if you are reporting marriage or a common-law relationship.
• Your address and the partner's address if these are different.
• Any supporting records that explain the change if the CRA later asks for them.

Keep this details for your own records. You do not need to send an unsolicited bundle of private documents through ordinary email. Instead, use the official update method and follow any later evidence request through the channel the CRA gives you.

Update the status through My Account

Start at the CRA status update page. Its online instructions take you to your own tax account, then the profile area and status details. Read the current value before selecting the change option. Next, enter the new status and start date, review the details and submit.

Afterward, retain the confirmation and check that the profile reflects what you entered. If the displayed date is wrong, do not submit a second change with a made-up date to compensate. Contact the CRA about correcting the record. A clear timeline is more useful than several conflicting entries.

If you cannot make the change online

The CRA also provides phone and written options. For a call, have your identity details and assessed tax details ready. For a written request, use the CRA's instructions for Form RC65 or a signed letter. These routes have their own requirements, so do not assume a brief message to a general contact address will update your account.

If you want another person to act for you, check the authorization rules first. A partner cannot automatically change your records merely because you share a home. Likewise, marriage does not mean you should share account passwords or authentication codes.

Check benefit notices after the change

A status change can lead to a recalculation because family net income affects benefits and credits. The result may be a different payment or a notice about amounts already paid. Read the period covered by any notice. Also compare the start date with your own timeline before assuming that the calculation uses the wrong year.

For example, a parent who separates may also need to report a change in the child's living arrangements. That is a separate factual question from status. Finally, update other government organizations that need the change. The CRA does not generally pass your new status to every agency that holds a record about you.

If you keep a paper record, write down the event date and the day you told the CRA. Keep those two dates apart. That note can help explain a later question about when the change took place.
