Child Tax Benefit Calculator Ontario Canada

Ontario's Child Tax Benefit (CTB) provides financial support to families with children under 18. This calculator helps you estimate your eligibility and monthly payments based on your family's income and number of children.

How Child Tax Benefit Works in Ontario

The Ontario government provides the Child Tax Benefit to help families with the costs of raising children. The amount you receive depends on your family's income and the number of eligible children in your household.

Payments are made monthly and are based on a sliding scale. The benefit is means-tested, meaning higher-income families receive smaller payments than lower-income families.

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

Eligibility Requirements

To qualify for the Child Tax Benefit in Ontario, you must meet the following criteria:

Be a resident of Ontario
Have at least one child under the age of 18 living in your household
Meet the income requirements (varies by family size)
Be a Canadian citizen, permanent resident, or protected person

The income thresholds change each year. For the most current information, check the Canada Revenue Agency website.

Formula Used

The Child Tax Benefit in Ontario is calculated using the following formula:

Monthly Payment = Base Amount × (1 - (Family Income / Income Threshold))

Where:

Base Amount = $250 per child (2023 rate)
Income Threshold = Varies by family size (see table below)
Family Income = Total household income before taxes

The payment is reduced by 1% for every $100 of family income above the threshold. If your income exceeds the threshold, you may not qualify for the full benefit.

Income Thresholds for Ontario Child Tax Benefit (2023)
Number of Children	Income Threshold
1	$45,000
2	$55,000
3	$65,000
4 or more	$75,000

Worked Example

Let's calculate the Child Tax Benefit for a family with two children and a household income of $48,000.

1. Determine the base amount: $250 per child × 2 children = $500

2. Find the income threshold: $55,000 (for 2 children)

3. Calculate the reduction factor: (48,000 / 55,000) = 0.8727

4. Calculate the monthly payment: $500 × (1 - 0.8727) = $500 × 0.1273 = $63.65

This family would receive approximately $63.65 per month in Child Tax Benefit payments.
