Ontario Energy Tax Credit Calculator

Reviewed by Calculator Editorial Team

This Ontario Energy Tax Credit Calculator helps you determine how much you can claim as a tax credit for energy-efficient home improvements. The credit is available for eligible homeowners who make qualifying energy-saving upgrades to their primary residence.

How the Ontario Energy Tax Credit Works

The Ontario Energy Tax Credit is a provincial program designed to encourage homeowners to make energy-efficient upgrades to their homes. The credit reduces the amount of provincial sales tax (PST) you pay on qualifying energy-saving improvements.

Key Points

  • The credit applies to the PST portion of the total price of eligible improvements
  • You must be the owner-occupant of your home
  • Improvements must be completed and installed by a licensed contractor
  • The credit is available for a limited time and may change

The credit is calculated based on the total cost of eligible improvements and the applicable PST rate. The amount of the credit depends on the type of improvement and the current PST rate in Ontario.

Eligibility Requirements

To qualify for the Ontario Energy Tax Credit, you must meet several criteria:

  1. Homeownership: You must be the owner-occupant of your primary residence
  2. Improvement Type: The upgrades must be energy-saving improvements to your home
  3. Installation: Improvements must be installed by a licensed contractor
  4. Completion Date: Work must be completed within the program's timeframe
  5. Documentation: You must have receipts and invoices for all improvements

Common Eligible Improvements

  • Energy-efficient windows and doors
  • Insulation upgrades
  • High-efficiency furnaces and boilers
  • Solar water heating systems
  • Heat pumps
  • Energy-efficient lighting

How to Calculate Your Credit

The Ontario Energy Tax Credit is calculated using the following formula:

Formula

Credit Amount = (Total Cost of Improvements × PST Rate) × Credit Percentage

Where:

  • Total Cost of Improvements - The total price of all eligible improvements
  • PST Rate - The current provincial sales tax rate (typically 8%)
  • Credit Percentage - The percentage of PST that can be credited (varies by improvement type)

The credit percentage varies depending on the type of improvement. For example, insulation upgrades typically have a higher credit percentage than window replacements.

You can use the calculator on this page to estimate your potential credit amount based on your specific improvements.

Worked Examples

Example 1: Insulation Upgrade

You install $5,000 worth of insulation in your home. The current PST rate is 8%, and insulation has a credit percentage of 50%.

Calculation

Credit Amount = ($5,000 × 0.08) × 0.50 = $200

You would receive a $200 credit against your PST liability.

Example 2: Window Replacement

You replace your windows with energy-efficient models costing $10,000. The current PST rate is 8%, and windows have a credit percentage of 30%.

Calculation

Credit Amount = ($10,000 × 0.08) × 0.30 = $240

You would receive a $240 credit against your PST liability.
