Updated Checked by the Tax-Services.ca editorial team How we check
Easy taxes in Canada mostly come down to one habit: keep your paperwork in one place all year. If you’re an employee with a T4 and a few receipts, you can file yourself in under an hour. On a $40,000 taxable income in Ontario, the engine on this site puts your federal and Ontario tax at $5,110.78, about 12.8% of what you earned.
When is doing it yourself the easy option?
When your income arrives on slips and nothing else is going on, which is true for a lot of employees, students and retirees, and that’s the whole point of calling it easy. A T4 from one employer, a T5 from the bank, a few receipts for donations or medical costs. Tax software pulls most of that in for you, and the CRA says you can get help from free community tax clinics if your situation is modest and simple.
It stops being easy when a business shows up. Self-employment means keeping books, tracking expenses and possibly paying tax in instalments. That’s where an accountant or bookkeeper earns their fee. What firms charge couldn’t be confirmed, so ask for a quote in writing before you agree to anything.
What does an easy filing day look like?
Take Lena, a retail worker in Kingston with one T4 and a $200 charitable donation. She opens her software on a Sunday morning, types in the box numbers from her T4, adds the donation receipt and checks the refund figure. Forty minutes, one coffee, done. The trick wasn’t skill. It was that her slip, her receipt and last year’s notice of assessment were all in one folder.
If you can say the same about your own paperwork, you’re already most of the way there.
What do you need to keep, and for how long?
The CRA says to keep your records for at least six years. That means a copy of each return, every notice of assessment, receipts, bank statements and anything that backs up a deduction or credit you claimed. A folder on your computer works. So does a shoebox, though it’s slower to search.
| Item | Date for the 2025 return |
|---|---|
| File and pay, most individuals | April 30, 2026 |
| File, if you or your spouse are self-employed | June 15, 2026 |
| Pay, if you or your spouse are self-employed | April 30, 2026 |
| Keep your records | At least six years |
The 2026 return is filed in 2027, and the CRA hasn’t published those dates yet. The usual pattern is the same, but check the CRA page before you rely on it.
What does easy tax look like in numbers?
Take $40,000 of taxable income in Ontario, using only the basic personal amounts. The income tax calculator gives $3,296.72 of federal tax and $1,814.06 for Ontario, which includes a $450 health premium. Total: $5,110.78.
Now say your employer already took $6,000 off your pay during the year. You’d get about $889 back. (The $6,000 is made up for the example, so use your own T4.) The tax refund calculator lets you try your own figures before you file.
Flip it around. If only $4,500 had come off your paycheques, you’d owe about $611 when you file ($5,110.78 minus $4,500). A few hundred bucks owing isn’t a disaster, but it’s a reason to look at your withholding.
Where does bookkeeping fit in?
Bookkeeping is the record of money in and money out.
If you run a small business, you need it monthly, not in April. Write down each sale and expense as it happens, keep the receipt, and you’ll be able to work out your income in minutes instead of days.
Self-employed people also pay both halves of CPP. The self-employed tax calculator shows the bill, though it doesn’t include EI, and deductions there lower income tax but not CPP. If you expect a sizeable balance every year, look at tax instalments too, since the CRA may ask for payments during the year instead of one lump sum in April.
What mistakes cost people money?
Missing a slip is the classic one. Most slips are out by the end of February, so if one hasn’t shown up by the end of March, contact whoever issued it. Paying late is the other. Your filing date can be June 15 and the money is still due April 30, and the current interest rate wasn’t confirmed here, so check the CRA’s page.
Some claims trip people up too: credits you can’t support with a receipt, or a spouse’s income put on the wrong return. The tax credits calculator covers federal credits only, so it won’t show provincial ones.
Where these figures come from
Tax rates and brackets are the 2026 figures from the Canada Revenue Agency and the Ontario government. The filing dates are the CRA’s dates for the 2025 return, and the six-year rule is from its record-keeping guidance. No government body has reviewed or endorsed what you read here.
Frequently asked questions
Can I do my taxes myself in Canada?
Yes, if your income comes on slips like a T4. Certified tax software handles most of the steps, and the CRA lists free community clinics for simple returns.
How long should I keep my tax records?
At least six years. Keep the return, notices of assessment, receipts and bank statements that support your claims.
When was the deadline for the 2025 return?
April 30, 2026 for most people. Self-employed people had until June 15, 2026 to file, but any tax owing was still due April 30.
Do I need an accountant for a small business?
Not always. A bookkeeper or accountant helps once your books get complicated or you're unsure what you can deduct. We couldn't confirm typical fees, so get a written quote.
Are the 2026 tax dates out yet?
Not on the CRA pages we checked. The usual dates are April 30 and June 15, but wait for the CRA to confirm.
