Child Tax Credit Ontario Calculator

The Ontario Child Tax Credit (CTC) is a refundable tax credit that helps families with the cost of raising children. This calculator helps you estimate how much you might qualify for based on your family's income and the number of eligible children.

How the Ontario Child Tax Credit Works

The Ontario Child Tax Credit provides a refundable tax credit that reduces the amount of income tax you owe. The credit is calculated based on your family's net income and the number of eligible children in your household.

Formula Used

The basic formula for calculating the Ontario Child Tax Credit is:

CTC = (Basic Credit × Number of Eligible Children) + (Additional Credit × Number of Eligible Children)

Where:

Basic Credit is $6,500 per child for the first child and $5,500 per child for each additional child
Additional Credit is $500 per child if your net income is below $45,000

The credit is phased out for families with higher incomes. The maximum credit is available to families with a net income of $45,000 or less. For each $1,000 of income above $45,000, the credit is reduced by $150 per child.

Important Notes

The Ontario Child Tax Credit is separate from the federal Child Tax Benefit (CTB). You may qualify for both credits.

Eligible children include your biological, adopted, and stepchildren, as well as children you are legally responsible for.

The credit is available for children up to age 18, or up to age 24 if they are full-time students.

Worked Examples

Let's look at two examples to illustrate how the Ontario Child Tax Credit works.

Example 1: Low-Income Family

A single parent with one child has a net income of $30,000. They qualify for:

Basic Credit: $6,500 × 1 = $6,500
Additional Credit: $500 × 1 = $500
Total Credit: $6,500 + $500 = $7,000

Example 2: Higher-Income Family

A family with two children has a net income of $55,000. They qualify for:

Basic Credit: ($6,500 × 1) + ($5,500 × 1) = $12,000
Additional Credit: $500 × 2 = $1,000
Phase-Out Reduction: ($55,000 - $45,000) × $150 = $15,000
Total Credit: $12,000 + $1,000 - $15,000 = $1,000

Income Level	Number of Children	Credit Amount
$30,000	1	$7,000
$45,000	2	$13,000
$55,000	2	$1,000
