Tax credits and benefits
Types of tax credits and benefits
There are two types of tax credits:
- non-refundable tax credits can reduce the amount of tax that you owe, for example you may receive a tax credit for donations and gifts
- refundable tax credits can reduce the amount of tax that you owe but are also available even if you don’t owe any tax, such as the Ontario Energy and Property Tax Credit
Benefits can help with various living expenses, such as raising children, housing, loss of income and medical expenses.
Read the Canada Revenue Agency’s (CRA’s) General Income Tax and Benefit Guide and Forms Book to learn more about which tax credits you can claim.
With the Ontario Child Care Tax Credit, you could get back up to 75% of your eligible child care expenses. It applies to eligible child care options, including care in centres, homes and camps.
The Low-Income Workers Tax Credit provides up to $850 each year in Ontario personal income tax relief to low-income workers, including those earning minimum wage.
How to apply for tax credits and benefits

Income tax basics
About income tax
You may pay tax on the income you make.
The amount you pay is based on how much income you earn in a year. You can reduce or eliminate the amount of income tax you need to pay by claiming tax credits and certain expenses. For example, the basic personal amount, a non-refundable tax credit, allows every Canadian resident to earn more than $10,000 each year before any income tax is payable.
How income tax works
Federal and Ontario income taxes are paid to the Canada Revenue Agency (CRA), which is part of the federal government.
Income tax is commonly taken off your pay by your employer, or off your pension, and sent directly to the CRA. You may also have to calculate the tax you owe and send a payment to the CRA.
Each year, you should file a tax return with the CRA to:
- report the income you’ve made
- ensure you’ve paid the correct amount of income tax
- access tax credits and benefits
Learn more about how much tax you should pay on each portion of your income.

You have to report any taxable income you earn inside and outside Canada when you file your tax return. This includes:

- self-generated income (for example, a home business, selling goods or services online, earning tips)
- rental income, including renting out a portion of your home
- investments (such as interest, dividends and capital gains)
- your pension
Types of non-taxable income
You do not have to report certain non-taxable amounts as income, including:
- most lottery winnings
- elementary, secondary and post-secondary school scholarships

After the CRA processes your tax return, you will receive a notice of assessment. The notice of assessment will tell you if you:
- paid too much income tax and are eligible for a tax refund
- paid too little income tax and have to pay the CRA, in either a lump sum or smaller amounts throughout the following year
- are eligible to get money back through tax credits and benefits
