⚖️ The 40% to 60% Custody Rule:
The CRA defines shared custody when a child lives with each parent on a relatively equal basis (between **40% and 60% of the time**). In this scenario, **both** parents are recognized as co-primary caregivers and each will receive exactly **50% of the CCB payment** they would have been entitled to under sole custody.

CRA Reporting & Application Mandates
Co-parents must carefully report changes in marital status and custody arrangements to avoid tax debts:
- Notification Window: You must notify the CRA of a shared custody arrangement by the **end of the month following the month** the change occurred.
- Application Process: If you were already receiving CCB, submit the change via CRA My Account (*"RC66 - Canada Child Benefits Application"*). Both parents must file independent applications to set up the split payments.
- Avoid Overpayments: If one parent continues to claim 100% of the CCB after transitioning to shared custody, the CRA will retroactively audit the account and issue an overpayment debt notice requiring the excess funds to be repaid.
