CRA Marital Status Change After Divorce: Deadlines, CCB, and GST Credits
CRA Marital Status Change After Divorce: Deadlines, CCB, and GST Credits
You must report your change in marital status to the Canada Revenue Agency by the 20th day of the month following your separation or divorce. Miss this deadline and you risk CCB overpayments you'll have to repay, incorrect GST/HST credits, and years of tax returns filed under the wrong status.
The Reporting Deadline
CRA requires notification of a marital status change by the 20th day of the month after the month your status changed. For separation, your status changes after you've been living apart for 90 consecutive days.
Example: If you separated on March 15, the 90-day clock means your official "separated" status begins on June 13. You must notify CRA by July 20.
For a divorce that was already preceded by separation (the usual case in Alberta, where 12 months of separation is required), your status changed at the 90-day separation mark — not the divorce date. If you already reported the separation, you don't need to report the divorce separately (your status remains "separated" or "divorced" — both are treated identically for tax purposes).
How to Report
Option 1: CRA My Account (fastest)
Log in to your CRA My Account online. Navigate to "Personal information" → "Marital status" → update to "Separated" or "Divorced." Takes effect immediately.
Option 2: Form RC65
Complete and mail Form RC65 (Marital Status Change) to your tax centre. Include:
- Your SIN
- Your new marital status and the effective date
- Your ex-spouse's name and SIN (if known)
- Your current address
Option 3: Phone
Call the CRA individual tax enquiries line (1-800-959-8281). Have your SIN and personal information ready for identity verification.
The 90-Day Separation Rule
CRA doesn't consider you "separated" until you've lived apart for 90 consecutive days. This is separate from the Divorce Act requirement of 12 months of separation before you can file for divorce.
The 90-day rule matters because:
- Benefits are recalculated from the date your status officially changes
- You cannot claim single-parent CCB amounts until 90 days have passed
- Your previous year's tax return may need to be filed as "married" even if you separated that year
Exception: If you reconcile for less than 90 days and separate again, the clock resets. If you reconcile for more than 90 days, you're back to "married" status.

Canada Child Benefit Recalculation
Once CRA processes your marital status change, it recalculates the Canada Child Benefit based on your individual adjusted family net income rather than your combined household income.
For the lower-earning spouse, this usually means a significant increase in monthly CCB payments. For the higher-earning spouse, CCB may decrease or be eliminated entirely.
Key points:
- CCB is paid to the parent who is primarily responsible for the child's care
- If you have shared custody (roughly equal time), you can split the CCB — each parent receives 50% of the amount calculated on their individual income
- You must notify CRA of custody arrangements in addition to the marital status change
- Retroactive adjustments may apply — CRA recalculates from the effective date of your status change and issues catch-up payments (or requests repayment of overpayments)
Warning: If you delay reporting, CRA continues calculating CCB based on your combined marital income. Once you report, the retroactive adjustment can result in a large lump sum owed back to CRA if you were the higher-income household. Report promptly to minimize this.
GST/HST Credit Recalculation
Your GST/HST credit is also recalculated based on individual income once your status changes. The quarterly credit amount typically increases for the lower-income ex-spouse. CRA adjusts this automatically once you report — no separate application needed.
Filing Your Tax Return After Divorce
For the tax year of your separation:
- If you were separated for 90+ days by December 31, file as "separated" for the entire year
- If you reconciled or hadn't hit 90 days by December 31, file as "married"
- You can still claim the spouse or common-law partner amount for a spouse you supported if you separated during the year (but not if separated for the full year)
- Child care expenses are claimed by the lower-income parent (which may now be you)
- Moving expenses for a new residence after separation are deductible if you moved to be closer to work
The Complete Financial Checklist
Reporting to CRA is one step in the broader post-divorce financial transition. You also need to:
- Split CPP credits (Form ISP1901 to Service Canada — separate from CRA)
- Update your address with CRA if you've moved
- Cancel direct deposit to a joint bank account
- Update your RRSP deduction room (T2220 transfers affect this)
- File a T1-ADJ if you need to amend a prior year's return
