How Ontario Tax Calculation Works

The Ontario provincial tax calculation is based on progressive tax brackets. Here's how it works:

The first $44,763 of taxable income is taxed at 5.05%
The next $44,762 ($44,763 - $89,525) is taxed at 9.15%
The next $60,475 ($89,525 - $150,000) is taxed at 11.16%
The next $70,000 ($150,000 - $220,000) is taxed at 12.16%
Any income above $220,000 is taxed at 13.16%

Formula Used

The Ontario provincial tax is calculated as follows:

if (income <= 44763) {
    tax = income * 0.0505;
} else if (income <= 89525) {
    tax = 44763 * 0.0505 + (income - 44763) * 0.0915;
} else if (income <= 150000) {
    tax = 44763 * 0.0505 + 44762 * 0.0915 + (income - 89525) * 0.1116;
} else if (income <= 220000) {
    tax = 44763 * 0.0505 + 44762 * 0.0915 + 60475 * 0.1116 + (income - 150000) * 0.1216;
} else {
    tax = 44763 * 0.0505 + 44762 * 0.0915 + 60475 * 0.1116 + 70000 * 0.1216 + (income - 220000) * 0.1316;
}

This progressive tax system means that higher-income individuals pay a higher effective tax rate than lower-income individuals.

Worked Example

Let's calculate the Ontario provincial taxes for someone with $100,000 in taxable income:

First $44,763: $44,763 × 5.05% = $2,264.55
Next $44,762: $44,762 × 9.15% = $4,076.38
Remaining $10,475: $10,475 × 11.16% = $1,165.28
Total tax: $2,264.55 + $4,076.38 + $1,165.28 = $7,506.21

Using the calculator with these inputs would show an estimated provincial tax of $7,506.21 for this example.
