When your income or family changes

Updated July 31, 2026 · figures for the July 2026 – June 2027 benefit year

The CCB is recalculated automatically every July, but several changes have to be reported as they happen. Reporting late is what creates overpayments — and the CRA recovers overpayments by withholding future benefit payments, which is a much worse outcome than a smaller cheque.

A useful way to hold the rule in your head: money changes once a year, family changes the moment they happen. Income flows through the July recalculation and nothing you do will make it arrive sooner. Everything about who lives in the household — children, partners, custody — takes effect the month after you report it.

Changes you must report right away

• A new child — by birth, adoption, or a child starting to live with you.
• A child leaving your care, including a change in custody arrangements.
• Marital status. Marriage or a new common-law relationship (12 continuous months, or immediately if you have a child together) raises your AFNI because your partner's income is added. Separation is only recognised after 90 consecutive days apart, but once recognised it is backdated to the date you separated.
• Address or banking details.
• A death in the family affecting the beneficiary or a child.

All of these can be updated in your CRA account, which is faster than mail and gives you a record with a date on it.

A raise does not change your benefit immediately

Income changes flow through the annual recalculation, not in real time. A raise in 2026 affects the payments starting in July 2027. This works both ways: if your income drops sharply this year, your benefit will not increase until the following July, which is why a job loss mid-year is financially harder than the headline numbers suggest.

You can see the effect in advance with the calculator — enter next year's expected income to know what your July payment will look like.

Separation: the 90-day rule

You cannot update your status to separated until you have been living apart for 90 consecutive days because of a breakdown in the relationship. Once you do, the change is applied from the original separation date, and your AFNI drops to your income alone — which usually raises your benefit substantially. Waiting to report it does not lose you money, but it does mean several months at the old, lower amount.

The reverse case is where people get caught: entering a new common-law relationship raises AFNI from the month it starts. Reporting it late produces an overpayment that will be clawed back.

A child turning 6 or 18

Both happen automatically, and both reduce your payment the month after the birthday. At 6, the maximum for that child drops from $8,157 to $6,883 per year. At 18, the benefit for that child ends entirely. Neither requires any action from you — but neither comes with a warning letter, so it is worth marking in advance.

File your taxes — both of you

The CCB depends on assessed tax returns. If you or your spouse has not filed, the CRA cannot calculate the entitlement and payments stop. This applies even with zero income. If you are behind by several years, file the missing returns — the CRA can reinstate the benefit retroactively for up to 10 years, which is often a large sum.

How overpayments are recovered

If you were paid more than you were entitled to, the CRA recovers it by withholding some or all of your future CCB, GST/HST credit and any tax refund until the balance is clear. There is no interest on CCB overpayments, but the withholding can be complete, which is why an unreported change can turn into several months with no payment at all.

If repayment would cause real hardship, taxpayer relief provisions exist and payment arrangements can be negotiated — but only if you contact the CRA rather than wait.

Death of a spouse or a child

Both must be reported, and both change the calculation immediately rather than at the next July recalculation. If your spouse or common-law partner dies, your AFNI becomes your income alone from the following month, which usually increases the benefit. If a child dies, the benefit for that child ends the following month; the CRA asks to be told within the month so that no overpayment builds up during a period when nobody wants a letter about money.

Leaving Canada

The CCB requires residency for tax purposes. A holiday does not affect it; emigrating does, from the month after you cease to be a resident. Long absences are judged on residential ties — a home, a spouse or dependants left in Canada, bank accounts, a driver's licence — rather than on a fixed number of days. If you are leaving for an extended period and are unsure whether you remain a resident, Form NR73 asks the CRA to make a determination, and having that answer in advance is far cheaper than an overpayment assessed two years later.

Moving to another province

The federal CCB is identical across Canada, so the federal part of your payment does not change. What does change is the provincial or territorial top-up, and some of those are significant. If you have moved, check what your new province adds and update your address promptly — the top-ups follow your address on file, not where you actually live.
