CCB and Shared Custody: What Separated Parents Should Know

When parents separate, there are a lot of practical details to sort out: parenting schedules, address changes, support payments, school forms, daycare arrangements, and tax filings.

One item that is easy to overlook is the Canada child benefit, often called the CCB.

The CCB is separate from the child care expense deduction. It’s a monthly benefit administered by the Canada Revenue Agency, and when parents separate or begin sharing custody, the amount paid – and who receives it – can change.

What is the Canada child benefit?

The CCB is tax-free and is not reported as income on the recipient’s personal tax return.

Note: The CRA also administers child and family benefit programs for certain provinces and territories who offer additional assistance to help with the cost of raising a family. Some of these benefits are combined with the CCB payment, into a single monthly payment, while others are paid separately. For example:

In British Columbia, the BC Family Benefit (BCFB) is a tax-free monthly payment to families with children under the age of 18 and works similarly as the CCB. It’s determined using the same period (July to June), based on adjusted family income, and is paid out combined with the CCB monthly payment.

Who is eligible for the Canada child benefit?

To be eligible for the CCB for a child, you must meet all the following conditions:

You live with a child who is under 18 years old,
You are primarily responsible for the child’s care and upbringing,
You are a Canadian resident for tax purposes,
You (or your spouse or common law partner) are a Canadian citizen, permanent resident, protected person, qualifying temporary resident, or an individual registered or entitled to be registered under the Indian Act, and
You are not applying for a foster child who is already receiving the Children’s Special Allowance.

Being ‘primarily responsible’ generally means being responsible for the child’s day-to-day care, such as supervising daily needs, arranging child care, and making sure medical needs are met. For shared custody parents, the Income Tax Act requires each parent to primarily fulfil the responsibility for care and upbringing when residing with the child, as “primarily responsible” is assessed while the child resides with the parent in shared custody.

How is the Canada child benefit calculated?

The CCB amount depends on several factors, including:

The number of eligible children in the household,
The age of each child,
The family’s adjusted net income,
Whether the child is eligible for the child disability benefit,
Whether the child is in a shared custody arrangement, and
The province or territory of residence (where the related benefits apply).

CCB payments are recalculated every July and are based on the previous year’s adjusted family net income.

For example, the July 2026 to June 2027 payment period is based on the family’s 2025 adjusted net income.

As CCB amounts and income thresholds can change from one benefit period to the next, families should check CRA’s current calculation tool to estimate payment amounts.

For the July 2026 to June 2027 benefit period, maximum annual amounts are $8,157 per child under age 6 and $6,883 per child aged 6 to 17, where adjusted family net income is below $38,237. Amounts phase out gradually above that threshold. As CCB amounts are indexed annually, families should check CRA’s current calculation tool each July when the benefit year begins.

What changes after separation?

For CCB purposes, a person is generally considered separated after they have lived separate and apart from their spouse or common-law partner because of a relationship breakdown for at least 90 days. Once the 90 days have passed, the effective date of separation is the date the parents started living apart. The CRA generally requires notification by the end of the following month following marital status changes, however in separation situations, asks individuals to wait until 90 days have passed before notifying the CRA.

This matters as benefits are calculated using adjusted family net income. If a parent’s marital status changes from married or common-law to separated, CRA will recalculate the benefit using the updated family situation.

After the parents have been separated for 90 consecutive days because of a relationship breakdown, they should update CRA rather than wait until tax filing season.

It is also worth noting that if a separated parent later remarries or enters a new common-law relationship, the new partner’s income will be included in the adjusted family net income and used to calculate the CCB. This can reduce the benefit amount, even if the children are from a previous relationship. CRA recalculates the benefit after a marital status change is reported.

To apply for the CCB or update an application after a new child arrives, parents can apply through CRA My Account, through birth registration, or by completing Form RC66, Canada Child Benefits Application. To report a marital status change to CRA (including separation, divorce, or a new common-law relationship), Form RC65, Marital Status Change, can be submitted through CRA My Account or by mail.

What counts as shared custody for the Canada child benefit purposes?

CRA generally looks at where the child lives, to determine which parent has custody.

The CRA states that shared custody applies if the child lives with each parent between 40% and 60%, and the Income Tax Act also states the parent must reside with the child at least 40% of the time in the month, or on an approximately equal basis, in the relevant month.

Examples include, if the child lives with you:

Every other week, or
Three days a week out of seven.

In shared custody, both individuals should apply for the CCB, and CRA determines entitlement. Where, parents cannot privately agree that one parent will receive 100% if the statutory shared custody criteria are met. CRA says both individuals should apply where the child lives with each parent at least 40% of the time or on approximately equal basis. A private agreement between parents does not override the Income Tax Act rules for CCB entitlement.

A parent is considered to have full custody when the child lives with one parent more than 60% of the time. Note that CRA will accept nuances to this such as due to illness or summer vacation schedules without necessarily defeating shared custody arrangements however this should be the basis and alteration should be done carefully.

For example, one parent has weekend custody rights only. The other parent would have full custody for CCB purposes.

Having full custody allows the parent to apply for the CCB, while the parent without cannot receive the CCB for that child for that period – unless they otherwise meet the temporary-period rules.

Note: Once you’ve applied for the CCB, even if you have no income, both spouses and common-law partners must file tax returns every year to continue receiving the benefit (and related provincial and territorial payments, if applicable).

Parenting time is not always the same as ‘residing with’ the child

A recent Tax Court of Canada case, Ginevro v. The King, 2026 TCC 23, illustrates that CCB shared custody turns on whether the child resided with the parent for the required time, not simply whether the parent had meaningful parenting time. The facts of each arrangement matter.

For CCB purposes, the shared custody test is not simply about counting every hour a parent spends with a child. CRA looks at whether the child lives with each parent for the required amount of time.

This means the focus is on where the child actually resides, including where their ordinary routines take place, where they sleep, where their belongings are kept, and which home they regularly return to.

The distinction matters because family law parenting time and the tax concept of residing with a child are not always the same thing. A parent can have meaningful involvement in a child’s life without meeting CRA’s shared custody threshold for CCB purposes.

This is why documentation matters, especially where parenting schedules are informal, change during the year, or do not clearly show where the child was actually living.

How are Canada child benefit payments split in shared custody?

Where CRA considers the parents to be in a shared custody agreement, each eligible parent generally receives 50% of the amount they would have received if the child lived with them full-time.

The important part is that each parent’s amount is based on their own adjusted family net income, meaning, two parents might not receive the same monthly amount.

What if the custody change is temporary?

In some cases, the parent who has the child for a temporary period (of at least one month) may be able to apply for the CCB payments for that period when the child is living with them. When the child returns to live with the other individual, that other individual needs to reapply to start getting payments again.

For example, a child may usually live with one parent full-time but spends the summer months with another parent.

Temporary changes should be handled carefully so that CRA’s records match where the child is actually living.

What records should separated parents keep?

CRA may ask for documents to confirm eligibility, marital status, residence, or who has primary responsibility for the child.

Helpful records may include:

Signed separation agreement or court order showing the parenting arrangement,
A parenting schedule or calendar showing where the child lived,
School or daycare records showing the child’s address and emergency contacts, and
Letters from a school, daycare, doctor, or other person with knowledge of the arrangement.

Accurate records can be especially important where the actual schedule is different from the written agreement, or where parents disagree about whether the 40% threshold is met.

Final thoughts: Update the CRA and keep a paper trail

The Canada child benefit can be a significant payment, and shared custody can make the calculation more complicated.

For separated parents, the key questions are:

Where does the child actually live?
Does each parent meet the 40% to 60% shared custody range?
Has the eligible parent(s) applied?
Has CRA been notified of the marital status or custody change?
Do the parents have records to support the arrangement if CRA asks?

If your family situation changes during the year, it is worth reviewing your CCB details before assuming the payments are correct.
