Where the taxable income is calculated as:

Taxable Income = Gross Income - Basic Personal Amount

Net income is calculated as:

Net Income = Gross Income - Ontario Tax

Worked Example

Let's calculate the Ontario tax for a single filer with $60,000 gross income:

Taxable income = $60,000 - $11,474 = $48,526
Tax on first $43,906 = $43,906 × 5.05% = $2,212.73
Tax on next $4,617 = $4,617 × 9.15% = $420.99
Total Ontario tax = $2,212.73 + $420.99 = $2,633.72
Net income = $60,000 - $2,633.72 = $57,366.28

Using the calculator with these numbers would show the same results.
