Worked Examples

Example 1: Single Child, Below Income Limit

A family with one child has a net income of $30,000. Their income limit is $46,605.

Calculation: ($46,605 - $30,000) × $1,000 = $16,605

This family would receive a Trillium Tax Credit of $16,605.

Example 2: Two Children, Above Income Limit

A family with two children has a net income of $65,000. Their income limit is $59,250.

Calculation: ($59,250 - $65,000) × ($1,000 + $500) = -$5,750 × $1,500 = -$8,625

This family would not receive any credit because their income exceeds the limit.

Example 3: Three Children, Partial Credit

A family with three children has a net income of $75,000. Their income limit is $71,895.

Calculation: ($71,895 - $75,000) × ($1,000 + $500 + $500) = -$3,105 × $2,000 = -$6,210

This family would not receive any credit because their income exceeds the limit.
