Formula Used

The calculator uses the following simplified formula to estimate your Ontario tax refund:

Estimated Refund = Taxable Income × Tax Rate - Deductions

Where:

Taxable Income - Your total income after deductions
Tax Rate - Progressive tax rates based on filing status
Deductions - Standard deductions for your filing status

The Ontario tax system uses progressive tax rates that increase as income rises. The standard deductions for 2018 were:

Single filers: $11,474
Married couples: $22,948

Worked Example

Let's calculate the estimated refund for a single filer with $50,000 in taxable income:

Taxable Income: $50,000
Filing Status: Single
Tax Rate: 20.05% (for income between $42,961 and $85,923)
Deductions: $11,474

Estimated Refund = ($50,000 × 0.2005) - $11,474

Estimated Refund = $10,025 - $11,474 = -$1,449

This example shows an estimated negative refund, meaning the filer would owe additional taxes rather than receive a refund. The actual result may vary based on specific deductions and credits.
