Calculate Child Tax Benefit Ontario

The Ontario Child Tax Benefit (CTB) is a monthly payment provided by the Government of Ontario to help families with the cost of raising children. This calculator helps you determine how much you may be eligible to receive based on your family's income and the number of eligible children.

How the Ontario Child Tax Benefit Works

The Ontario Child Tax Benefit is a monthly payment that helps families with the cost of raising children. The amount you receive depends on your family's income and the number of eligible children in your household.

Key Features

Provides financial support to families with children under 18
Amount varies based on family income and number of eligible children
Paid monthly, typically in two installments
Part of Ontario's broader child benefit system

Payment Structure

The CTB is paid in two installments each month. The first payment is usually made in early February and the second in early April. The total annual amount you receive may be higher than the monthly amount multiplied by 12 due to this payment structure.

Note: The Ontario Child Tax Benefit is separate from the federal Canada Child Benefit (CCB). Families may be eligible for both benefits.

Eligibility Requirements

To qualify for the Ontario Child Tax Benefit, you must meet certain criteria regarding your income and the number of eligible children in your household.

Income Limits

The maximum income for eligibility varies based on the number of children in your household. For the 2023 tax year, the income limits are:

Number of Eligible Children	Maximum Annual Income
1	$52,900
2	$60,500
3	$68,100
4 or more	$75,700

Eligible Children

Children must be:

Under 18 years old
Canadian citizens or permanent residents
Living with you for at least six months of the year
Not living with a parent who has custody of the child

Formula: Eligible = (Number of children under 18) - (Number of children living with a parent who has custody)

How to Calculate Your CTB

The amount of the Ontario Child Tax Benefit is calculated based on your family's income and the number of eligible children. The formula used is:

CTB Amount = Base Amount × (1 - (Family Income / Maximum Income))

Where:

Base Amount = $2,300 per child (2023 rate)
Maximum Income = Based on number of eligible children (see table above)
Family Income = Your family's annual income

Calculation Steps

Determine the number of eligible children in your household
Calculate your family's annual income
Find the maximum income for your number of eligible children
Apply the formula to calculate your monthly CTB amount

Example Calculation

For a family with 2 eligible children and an annual income of $45,000:

Maximum Income = $60,500 (for 2 children)

CTB Amount = $2,300 × (1 - ($45,000 / $60,500))

CTB Amount = $2,300 × 0.25 = $575 per child

Total Monthly CTB = $575 × 2 = $1,150

Worked Examples

Example 1: Single Parent with One Child

Family income: $30,000

Number of eligible children: 1

Maximum income: $52,900

CTB Amount = $2,300 × (1 - ($30,000 / $52,900))

CTB Amount = $2,300 × 0.43 = $989

Total Monthly CTB = $989

Example 2: Two Parents with Two Children

Family income: $70,000

Number of eligible children: 2

Maximum income: $60,500

CTB Amount = $2,300 × (1 - ($70,000 / $60,500))

CTB Amount = $2,300 × (-0.16) = -$368

Total Monthly CTB = $0 (income exceeds maximum)
