Air Quality Improvement Tax Credit


Take Advantage of the 25% Small Businesses Air Quality Improvement Tax Credit

Small Businesses Air Quality Improvement Tax Credit

To encourage small businesses to invest in better ventilation and air filtration to improve indoor air quality, the Government proposes to introduce a temporary Small Businesses Air Quality Improvement Tax Credit. Businesses would receive the credit on eligible expenses incurred between September 1, 2021, and December 31, 2022, related to the purchase or upgrade of mechanical heating, ventilation, and air conditioning (HVAC) systems and the purchase of standalone devices designed to filter air using high-efficiency particulate air (HEPA) filters, up to a maximum of $10,000 per location and $50,000 in total.

Tax Credit Rate and Limits

The tax credit would be refundable and have a credit rate of 25 percent that would apply to an eligible entity’s qualifying expenditures. An eligible entity would be limited to a maximum of $10,000 in qualifying expenditures per qualifying location and a maximum of $50,000 across all qualifying locations. The limits on qualifying expenditures would need to be shared among affiliated businesses. Consistent with the general treatment of business tax credits, credit amounts would be included in the taxable income of the business in the taxation year the credit is claimed.

Eligible Entities

Eligible entities for a taxation year would include unincorporated sole proprietors and Canadian-controlled private corporations with taxable capital employed in Canada of less than $15 million in the taxation year immediately preceding the taxation year in which the qualifying expenditure is incurred. For this purpose, the taxable capital of associated corporations is also counted.

Qualifying Expenditures

Qualifying expenditures would include expenses directly attributable to the purchase, installation, upgrade, or conversion of mechanical heating, ventilation and air conditioning (HVAC) systems, as well as the purchase of devices designed to filter air using high-efficiency particulate air (HEPA) filters, the primary purpose of which is to increase outdoor air intake or to improve air cleaning or air filtration.
