Ontario's Energy Heating Tax (EHT) is a provincial tax designed to encourage energy efficiency improvements in residential and commercial buildings. This guide explains how to calculate the EHT, including the formula, assumptions, and practical application.
What is Ontario EHT?
The Energy Heating Tax (EHT) is a financial incentive program implemented by the Ontario government to promote energy efficiency improvements in buildings. It provides tax credits to property owners who make qualifying energy-saving upgrades to their homes or commercial properties.
The program aims to reduce energy consumption, lower greenhouse gas emissions, and help homeowners and businesses save on energy costs. The tax credit amount is based on the energy savings achieved through the improvements.
How to Calculate Ontario EHT
Calculating the Ontario EHT involves determining the energy savings from your improvements and applying the appropriate tax credit rate. The process includes several key steps:
- Identify the energy-saving improvements you plan to make
- Calculate the energy savings from these improvements
- Determine the applicable tax credit rate based on the type of improvement
- Apply the formula to calculate the EHT amount
Use our calculator below to perform these calculations quickly and accurately.
The Formula
The Ontario EHT is calculated using the following formula:
EHT = Energy Savings × Tax Credit Rate
Where:
- Energy Savings is the amount of energy saved through improvements (in kWh/year)
- Tax Credit Rate is the applicable rate for the type of improvement (varies by program)
The tax credit rate varies depending on the type of energy-saving improvement and the program under which it qualifies. Common rates include:
- Residential improvements: $0.15 per kWh saved
- Commercial improvements: $0.10 per kWh saved
- Renewable energy installations: $0.20 per kWh saved
Worked Example
Let's walk through a practical example to illustrate how the calculation works.
Scenario
A homeowner installs energy-efficient windows that save 1,500 kWh of electricity per year. The applicable tax credit rate for window installations is $0.15 per kWh saved.
Calculation
EHT = 1,500 kWh × $0.15/kWh = $225
In this case, the homeowner would receive a tax credit of $225 for their energy-saving window installation.
