How to lower your tax bill using tax deductions and tax credits

With tax season looming in Canada, the question on everyone’s mind is how to lower taxes owed. Fortunately, there are many opportunities to offset your taxes owed. In this guide, you can find a list of commonly used tax deductions and tax credits that can reduce the amount you owe on your taxes.

How to lower your taxes owed

You can reduce your total tax bill using tax deductions and tax credits. A tax deduction is a reduction of taxable income. The lower your taxable income, the less tax you pay. A tax credit is a reduction of your tax payable. Tax credits are applied to your tax bill after your total taxes have been calculated. You can learn more about how to lower your taxes through the tax deductions and tax credits listed below.

Note there are other ways of keeping your tax bill low through various tax benefits. For example, controlling the tax bracket you’re in, using TFSAs and RRSPs and so on. However, these strategies are outside the scope of this article.

Tax deductions in Canada

Below is a list of tax deductions with information on how to maximize each tax deduction:

1. RRSP contributions

A registered retirement savings plan (RRSP) allows Canadians to save for retirement and lower the amount of tax they owe. The amount you contribute to your RRSP will be deducted from your taxable income, which means you will pay less tax.

RRSP contributions can serve as intentional tax planning or as immediate tax relief. Most Canadians who regularly earn an income open an RRSP and begin to contribute funds for retirement. You’re allowed to contribute to your RRSP for the first 60 days of the calendar year and apply those contributions to the previous tax year.

2. Childcare expenses

If you are a parent, you’re allowed to deduct childcare expenses against your income. In households with more than one parent, childcare expenses must normally be deducted from the parent who earns the lowest income.

The basic annual limit for childcare expenses is as follows:

• Children under 7: $8,000 per child
• Children aged 7 to 15: $5,000 per child
• Children eligible for the Disability Tax Credit: $11,000 per child, regardless of age.

• More on eligibility

  An eligible child must be under 16 years of age at some point in the year. The age limit does not apply if the child has an impairment or physical/mental function and is a dependant. An eligible child is defined as follows:

  • Your or your spouse’s or common-law partner’s child
  • A child who was dependent on you or your spouse or common-law partner, and whose net income in 2025 was $16,129 or less

  Eligible childcare expenses are any costs paid to another person to look after an eligible child that allows the parent to do the following:

  • Earn income from employment
  • Carry on a business
  • Attend school
  • Carry on research or similar work that a grant was received for

3. Moving expenses

If you relocated for a new job or to attend school, you can deduct certain moving expenses. To be eligible, you must be at least 40 kilometres closer to your new place of employment or education.

Eligible moving expenses include the following:

• Vehicle expenses, accommodations and meals for you and your family
• Fees incurred to change addresses on documents, such as a driver’s licence
• Cost of utility hookups and disconnections
• Title transfer costs for your new property

4. Home office expenses

Employees may be able to deduct certain expenses for working from home if they meet the CRA’s eligibility requirements. The temporary flat rate method introduced during the COVID-19 pandemic is no longer available. For 2023 and later tax years, eligible employees must use the detaileed method to calculate their home office expenses.

Detailed method

The detailed method lets eligible employees deduct the employment portion of certain actual home office expenses they paid. For current tax years, you generally must have been required to work from home and worked more than 50% of the time from home for at least four consecutive weeks. You may also qualify if you use your workspace only to earn employment income and regularly and continually meet clients, customers or others there.

You must keep supporting documents and have your employer complete and sign Form T2200, Declaration of Conditions of Employment. You cannot claim expenses that your employer reimburses or will reimburse.

Tax credits in Canada

Tax credits reduce your tax liability after your owed amount is calculated. In Canada, tax credits are either refundable or non-refundable. A refundable tax credit means you will receive the credit even if your tax owing is $0. A non-refundable tax credit is applied against your tax balance but if you don’t owe tax, a non-refundable tax credit won’t benefit you.

Below is a list of commonly used, non-refundable tax credits in Canada:

• Basic personal. The basic personal amount allows you to earn a certain amount of income before paying federal income tax. The maximum federal basic personal amount is $16,129 for 2025 and $16,452 for 2026.
• Spouse or common-law partner amount. If you support your spouse or common-law partner and their income was less than the basic personal amount, you can claim this tax credit.
• Age amount. If you’re over the age of 65 in the current tax year, you can claim this tax credit.
• Eligible dependants and caregivers. If you support an eligible dependant and/or are a caregiver, there are various tax credits you may be eligible to claim.
• Canada employment amount. If you reported employment income, you’re eligible for this tax credit. For 2025, the maximum claim is $1,471.
• Home buyers’ amount. If you purchased a home, you’re eligible for this tax credit and can claim up to $10,000 for the purchase of a qualifying home in 2025. A qualifying home is a property located in Canada that is registered in your name or your spouse/common-law partner’s name.
• Education tax credits. Your tuition, education and textbook amounts are eligible.
• Interest on student loans. If you paid interest on your student loans, you’re eligible for this tax credit.
• Disability amount. If you live with a disability and are eligible, you can claim this tax credit. There is an additional amount if you’re under the age of 18.
• Medical expenses. Certain medical expenses are eligible for this tax credit.
• Donations and gifts. If you made a gift of money or other property to registered charities and institutions, you’re eligible for this tax credit.

Helpful strategies for tax season

• Keep receipts. In general, you should keep records of everything you earn and spend. When tax season rolls around, it’ll be easier to make calculations and have documentation for credits and deductions. As you better understand the Canadian tax system, you’ll know what to save and what to toss.
• Read the annual tax guide. Every year, the CRA slightly adjusts how Canadians are taxed. But overall, the Canadian tax system doesn’t change much. If you read the annual tax guide each year, you’ll get better at understanding the system, filing your own taxes and tax planning.
• Tax planning. If you’re going to school soon or selling a large asset in the near future, you should plan your taxes accordingly. This can help you estimate how much you owe and identify opportunities to reduce your liability sooner.
• Hire a professional. Complex tax issues can arise that may be too difficult for you to navigate on your own. If you need help, consider hiring a professional. There are many who do tax returns for an affordable fee.

Bottom line

Tax benefits like tax credits and tax deductions can help lower your taxable income and taxes payable, as long as you know what’s eligible. Each time you complete a tax return, the better you’ll be at reducing your tax liability. If you’re ever stuck in the process, consider hiring a tax professional to assist you.
