Why did my CCB payment go down?

The Canada Child Benefit (CCB) is recalculated every July based on your prior-year Adjusted Family Net Income (AFNI) from your T1 return. The most common causes of a lower CCB: (1) Your income (or your spouse's income) increased from the prior year — the CCB reduces as AFNI increases; a $10,000 raise can meaningfully reduce monthly CCB. (2) A child turned 6 — the benefit rate for children under 6 is higher than for children 6–17; each birthday that crosses the under-6 threshold reduces the payment. (3) A child turned 18 — CCB stops for children who turn 18. (4) You or your spouse did not file your tax return — CRA uses filed income to calculate CCB; a missing return can reduce or halt payments. (5) Your marital status changed — separation or divorce requires updating your status with CRA, which changes the AFNI calculation.

How does family income affect CCB?

The CCB uses your Adjusted Family Net Income (AFNI) — meaning the combined net income of you and your spouse or common-law partner. CCB is highest for lower-income families and phases out as AFNI increases. Maximum CCB (2025–26): $7,787/year ($648.92/month) per child under 6; $6,570/year ($547.50/month) per child aged 6–17. Phase-out: begins at AFNI of approximately $36,502; a second, steeper reduction begins at approximately $79,087. Phase-out rates: for families with 1 child, CCB reduces by 7% of income above the first threshold and 3.2% above the second threshold. For families with more children, the phase-out rates are higher. Once AFNI reaches approximately $170,000–$200,000+ (depending on number of children), CCB can reach $0.

Why did my CCB change in July?

CCB amounts are recalculated each year starting in July, using your prior-year tax return income. The July reassessment is normal and expected — it is not a penalty or error. If your prior-year income was higher: your CCB for July forward will be lower. If your prior-year income was lower: your CCB will be higher starting July. For example: if your 2025 income is higher than your 2024 income, your CCB from July 2026 will be lower than the July 2025 rate. This is working as designed. Important: to receive any CCB at all from July onward, both you and your spouse (if applicable) must have filed your prior-year returns by June 1. Late filing delays CCB recalculation and can result in lower payments until returns are processed.

What happens to CCB if I separate from my spouse?

Separation affects CCB in several ways: (1) You must update your marital status at CRA My Account within 11 months of separation (though it is best done immediately). (2) The parent who primarily resides with the child is the eligible recipient — if the child lives primarily with you, you make the CCB claim. (3) CCB is recalculated using only your individual net income (not your ex-spouse's), which often increases the CCB for the primary caregiver. (4) If custody is shared equally (50/50), CRA splits the CCB between the two parents — each parent receives 50% of the benefit calculated based on each parent's own income. Not updating CRA promptly can result in overpayments (if the higher-income parent continues to receive full CCB) that must be repaid later.

Can CRA claw back previous CCB overpayments from my current payments?

Yes. If CRA determines you received more CCB than you were entitled to (commonly because a prior-year return was reassessed to show higher income, or because a life event was not reported), CRA issues a Notice of Debt for the excess amount. CRA may: offset future CCB payments against the overpayment until the balance is recovered; issue a separate Notice of Debt requiring a lump-sum repayment. If the overpayment results in financial hardship, you can contact CRA (1-800-387-1193) to request a repayment arrangement or taxpayer relief if the overpayment was due to CRA error or extraordinary circumstances.

Does going back to work after mat leave affect CCB?

Yes, if your return-to-work income significantly changes your annual income. CCB is based on the prior year's income, so: if you were on mat leave in 2024 and had low income, your CCB from July 2025 (based on 2024 income) will be relatively high; when you file your 2025 return (higher income from returning to work), your CCB from July 2026 will be lower. This creates a one-year lag effect. The transition is not a clawback — it is the normal recalculation cycle. There is no penalty; your CCB simply adjusts to reflect your actual current-year income level one year later.

Why hasn't my CCB increased after having a new baby?

CCB does not start automatically at birth — you must register your new child with CRA. How to register: (1) Apply for CCB when registering the birth with your province's vital statistics agency (the "Automated Benefits Application" in most provinces). (2) If you missed this, apply online through CRA My Account, or mail Form RC66 (Canada Child Benefits Application). CCB is paid retroactively up to 11 months after birth once registered. So if it has been 8 months and you have not registered, you will receive approximately 8 months of back payments when approved. If you have already registered and your CCB did not increase, contact CRA at 1-800-387-1193 — there may be processing delays or missing documentation.

Why Is My Canada Child Benefit (CCB) Lower Than Expected? 8 Common Reasons

CCB changes are most often income-driven and entirely expected — but some changes are CRA errors that require action.

Why CCB changes: quick reference

Cause	CCB direction	Action needed?
Prior year income increased	Down (recalculated July)	None — working as designed
Child turned 6	Down (rate drops at age 6)	None
Child turned 18	Down to $0 for that child	None
Spouse’s income increased	Down	None
Did not file prior-year return	Lower or suspended	File immediately
Spouse did not file	Lower or suspended	Spouse files immediately
Had new baby (not registered)	No increase	Register via CRA My Account
Separated from spouse	Up (if you are primary caregiver)	Update marital status at CRA
Reconciled with spouse	Down (combined income)	Update marital status at CRA
Prior year reassessment (higher income)	Down + possible repayment	Review NORA; dispute if incorrect

CCB maximum amounts 2025–26

Child age	Max annual benefit	Max monthly
Under 6	$7,787	$648.92
Age 6–17	$6,570	$547.50

These amounts are indexed annually to CPI. Phase-out begins at ~$36,502 AFNI.

The July recalculation explained

Every year CRA recalculates CCB in July:

CCB period July 2026 – June 2027 = based on 2025 tax return income
CCB period July 2025 – June 2026 = based on 2024 tax return income

Both you and your spouse must file by June 1 to avoid interruption. Late filers may see CCB reduced to $0 temporarily until the return is processed.
