Ontario Health Premium 2025 Thresholds Calculation

The Ontario Health Premium is a tax on household income that funds the province's healthcare system. For 2025, the premium is calculated based on your household income and the number of people in your household. This calculator helps you determine your premium amount based on the official 2025 thresholds.

How to Calculate Ontario Health Premium 2025

The Ontario Health Premium is calculated using progressive brackets based on your household income. The formula for the 2025 premium is:

Ontario Health Premium = (Household Income - Threshold) × Premium Rate

Where:

Household Income - Your total annual income before taxes
Threshold - The income level where the premium starts (varies by household size)
Premium Rate - The percentage applied to income above the threshold (5% for 2025)

The premium is only applied to income above the threshold. For example, if your household income is $100,000 and your threshold is $50,000, only $50,000 is subject to the premium.

Note: The 2025 thresholds and rates are subject to change. Always verify with the latest official government information before making financial decisions.
