A tax refund might feel like a bonus, but it actually means you overpaid the government throughout the year. The Canada Revenue Agency (CRA) collected more tax from you than you owed, and now it is returning the difference. Understanding how refunds work — and how to make the most of them — can help you keep more of your money when it matters most. This guide covers how tax refunds work in Canada, how long they take, how to check your status, what to do if yours is delayed, and how to increase or decrease your refund going forward.
How tax refunds work in Canada
A tax refund is money the government returns to you after you have paid more income tax than you owed for the year. Employers collect tax on behalf of the government from your paycheque, before it reaches your bank account. Employed individuals file an income tax return detailing their income, deductions, and credits before April 30 of the following year to determine the actual tax they owed.
If they paid more than they owe, the government refunds the difference. If they underpaid — likely because they have investment or other sources of income on which they have not yet paid any tax — they must pay what they owe by April 30.
The bigger the refund, the more interest, investment, and spending opportunities you lost out on throughout the year.
How long it takes to get your tax refund
The CRA typically sends your tax refund within 2 weeks if you have filed online, or within 12 weeks if you have filed a paper return. If you live outside of Canada, returns may take up to 16 weeks. If your tax return is flagged for an in-depth review, it may take longer.
To get your return as fast as possible, the CRA recommends signing up for direct deposit with your bank.
If the CRA holds your refund past the interest start date (the latest of: 30 days after the balance-due date, 30 days after you file, or the day you overpaid), they will pay you compound daily interest, between 1% and 5%. No interest is given for the overpayment collected and held throughout the year.
How to check your tax refund status
You can check the status of your tax refund through several channels.
CRA My Account: sign in to your CRA My Account online to view the Progress Tracker, which shows a step-by-step status bar indicating where your return sits in the processing queue and an estimated completion date.
MyCRA mobile app: download the MyCRA app for quick access to your refund status on the go.
By phone: call the CRA's Tax Information Phone Service (TIPS) at 1-800-267-6999 and select Telerefund. Have your Social Insurance Number (SIN), month and year of birth, and total income from line 15000 of your return ready.
The CRA recommends waiting 12 weeks after filing before contacting them about your refund status if you reside in Canada, or 16 weeks if you live outside of Canada.
Why you might not have received your tax refund
You may not get all or part of your refund if:
The amount is $2 or less
You owe child support payments
You owe the government any money, such as outstanding student loans or a previous tax balance
If none of these scenarios apply to you and you still have not received your refund after 12 weeks, contact the CRA.
How to increase your tax refund
One straightforward way to increase your tax refund is to pay more tax throughout the year. You can fill out Form TD1 to get your employer to increase the amount of tax collected from each paycheque.
Otherwise, you can increase your refund by decreasing your taxable income through deductions, or by decreasing your tax payable through credits.
Maximize your deductions
Deductions are specific categories of spending that the government has chosen to incentivize. They encourage you to spend money on these categories by allowing you to deduct the expenses from your income.
Lowering your income effectively reduces both your average tax rate and your tax payable — and therefore usually increases your tax refund. Deductions cannot reduce your income below zero.
Common deductions include:
Registered Retirement Savings Plan (RRSP) contributions — one of the most effective ways to lower your taxable income
Child care expenses — costs for daycare, camps, and other eligible care
Support payments for a spouse — deductible under certain conditions
Interest for a loan used to invest — interest on money borrowed for investment purposes
Union dues — annual professional or union membership fees
Maximize your credits
Whereas deductions reduce your income, credits reduce your tax payable. There are hundreds of boutique credits, both federal and provincial/territorial.
Some common non-refundable tax credits include:
Basic personal exemption
Disability credits
Medical credits
Canada Pension Plan (CPP) contributions
Adoption expenses
Post-secondary school tuition
Add up all your non-refundable credits and multiply by 14% (the federal non-refundable tax credit rate in 2026) to figure out roughly how much to subtract from your tax payable.
You can use your non-refundable tax credits to reduce your tax payable to zero — the CRA will not owe you money beyond that. But if you are eligible for refundable tax credits and the amount you owe in taxes is less than the total amount of credits, the CRA will dip into its own coffers to pay you. For instance, if you owe $1,000 in taxes but your refundable credit amount is $1,200, the CRA will pay you a refund of $200.
Some common refundable tax credits include:
Canada training credit
Multigenerational home renovation tax credit
Eligible educators school supply tax credit
Medical expense supplement
How to decrease your tax refund
There are two reasons you might want a smaller refund:
You need more cash flow throughout the year to live on.
You want to invest your money throughout the year in a high-interest savings account.
Let's say you need more cash month to month — high rent, debts to pay, a kid in daycare. You're planning to contribute a large amount to your RRSP, which will lower your taxes payable and leave you with a big refund. The government doesn't know that in advance, though: it withholds tax based on your gross salary alone, without accounting for any deductions or credits. By reducing the amount taken off each paycheque, you could free up a few hundred dollars (or more) each month to help cover your living expenses.
The same move can pay off even when cash flow isn't the issue. Say you're a high earner who ends up with a large refund every year. Rather than letting the CRA hold that money interest-free until it refunds you, you could reduce your withholding and move the difference into a high-interest savings account each month, earning interest on it in the meantime. The catch is discipline — it only works if you actually set the money aside instead of spending it.
In both cases, the mechanism is the same. If you're employed, you can apply to the CRA for a letter of authority using Form T1213, Request to Reduce Tax Deductions at Source. Once it's approved, you give the CRA's letter to your employer, who can then reduce the tax withheld from each paycheque.
How to calculate your tax refund
The easiest way to calculate your tax refund is to use an online tax calculator or have an accountant do the sums for you.
You can also do a rough reckoning on paper, but depending on how complex your financial situation is, it may take you some time. To do it, you will need 5 final numbers:
Income tax already paid
Total taxable income
Total deductions
Average tax rate
Total credits multiplied by 0.14 (in 2026)
From that point, the equation is:
Total income - total deductions = taxable income
Taxable income x average tax rate = tax on taxable income
Tax on taxable income - (sum of all non-refundable credits x 0.14) = tax payable
Tax payable - tax already paid + other refundable credits = refund
How to adjust your tax return
To adjust your tax refund, you must adjust your income tax return. Once you receive your notice of assessment, you can adjust different lines in your return. You can do this for the past 10 years of returns.
If you filed your return online, you can adjust certain lines of your return either through My Account, or through ReFILE. If you filed your return by paper, you can mail in a completed Form T1-ADJ, T1 Adjustment Request along with all supporting documents.
Making the most of your tax refund
Whether your refund is $200 or $2,000, putting it to work can make a meaningful difference over time. Consider directing your refund toward high-interest debt, topping up your RRSP or Tax-Free Savings Account (TFSA), or building an emergency fund.
And if you find yourself receiving a large refund year after year, it may be worth adjusting your payroll deductions so you keep more of your money throughout the year — and put it to use sooner.
