The last day for taxes Canada creeps up faster than you’d think. One minute you’re ringing in the new year, and the next you’re scrambling to gather receipts and T4s before the Canada Revenue Agency (CRA) deadline hits. If you’re reading this close to that date, don’t panic—we’ve got you covered with real, actionable strategies to file smart and avoid costly mistakes.
Here’s the truth: filing taxes at the last minute is stressful, but it doesn’t have to be chaotic. Whether you’re a salaried employee, self-employed, or juggling multiple income sources, understanding what happens on the last day for taxes Canada and how to prepare can save you money, headaches, and potentially an audit.
What Is the Last Day for Taxes Canada?
For most Canadian taxpayers, the last day for taxes Canada is June 15th of the year following the tax year. So if you’re filing for 2024 taxes, your deadline is June 15, 2025. This applies to individuals filing personal income tax returns.
Here’s the catch: while June 15th is the filing deadline, any taxes you owe are actually due by April 30th. Think of it like this—you get until June 15 to submit your paperwork, but if you owe money, the CRA expects payment two months earlier. That’s a critical distinction that trips up a lot of people.
For self-employed individuals, the deadline is June 15th for filing, but again, any balance owing is due April 30th. If you’re a partner in a partnership, your deadline might be different, so check with the CRA directly if that applies to you.
The CRA doesn’t budge on this date. No extensions, no “just one more day” negotiations. Miss it, and you’re looking at penalties, interest, and a potential audit. We’ll talk more about that later.
Pro Tip: Mark June 15th in your calendar right now—and set a reminder for April 30th for any balance owing. These dates aren’t suggestions; they’re firm deadlines with real financial consequences.
Why the Deadline Matters More Than You Think
You might be thinking, “It’s just a deadline. I’ll file whenever I can.” But here’s where it gets real: missing the last day for taxes Canada isn’t just an inconvenience—it triggers a cascade of financial penalties that compound over time.
First, there’s the late-filing penalty. If you file after June 15th and owe taxes, the CRA slaps you with a penalty of 5% of the unpaid balance plus 1% for each full month the return is late (up to 12 months). So if you owe $2,000 and file two months late, you’re looking at a penalty of $140 right off the bat. And that’s before interest.
Then comes interest. The CRA charges compound daily interest on any unpaid taxes. The rate changes quarterly, but it’s typically around 8-10% annually. Over time, that interest adds up fast. A $2,000 debt can easily become $2,500+ if left unpaid for a year.
Beyond the financial hit, there’s the psychological weight. Owing money to the CRA creates stress that lingers. Plus, if you’re consistently late, you risk triggering a full audit, which means the CRA will scrutinize every deduction, every receipt, every claim. That’s time-consuming and can result in reassessments that cost even more.
Here’s another angle: if you’re expecting a refund, filing on time means getting your money back faster. The CRA typically processes returns within two weeks if filed electronically. File late, and you’re just delaying money that’s rightfully yours.
Think of the last day for taxes Canada like a subscription renewal date. Miss it, and you’re not just paying late—you’re paying penalties and interest on top of what you already owe.
Critical Documents You Need Before Filing
The biggest reason people file late is scrambling for documents. Let’s fix that right now. Here’s what you absolutely need to gather before the last day for taxes Canada:
- T4 Slips: Your employer(s) should send these by the end of February. If you haven’t received one, contact your employer immediately. You can’t file without it.
- T4A Slips: If you received pension income, scholarships, bursaries, or other eligible payments, you’ll get a T4A.
- T5 Slips: Investment income (dividends, interest) comes on a T5. Your bank or investment firm sends these.
- T5007 Slips: If you received benefits like EI or CPP-D, you’ll get a T5007.
- Receipts for Deductions: Medical expenses, charitable donations, tuition, daycare, home office costs—keep everything. The CRA can ask for supporting documents up to six years after filing.
- Mortgage Interest Statement: If you’re claiming home office expenses, you might need this.
- Proof of Contributions: RRSP contributions, TFSA contributions, spousal RRSP contributions—have documentation ready.
- Business Records (if self-employed): Income statements, expense receipts, invoices, mileage logs, anything that supports your business income and deductions.
Pro move: create a folder (digital or physical) labeled with the tax year and start dumping documents in there throughout the year. By the time the last day for taxes Canada rolls around, you’re not hunting—you’re just organizing.
Missing documents? Contact the issuer immediately. The CRA has a resource page for tracking down missing T4 and T5 slips that can help.
Last-Minute Deductions You Might Be Missing
Here’s where people leave money on the table. As you’re scrambling to file before the last day for taxes Canada, don’t overlook these commonly missed deductions:
- Home Office Expenses: If you worked from home in 2024 (even part-time), you can deduct a portion of rent/mortgage interest, utilities, internet, and supplies. The CRA allows either a simplified method ($2 per square foot, up to 300 sq ft) or actual expenses. Most people don’t claim this because they think it’s complicated—it’s not.
- Professional Fees: Accountant, lawyer, tax advisor fees are deductible. This includes fees paid to file your taxes.
- Union Dues: If you’re a union member, these are fully deductible. Check our guide on whether union dues are tax deductible for specifics.
- Medical Expenses: Prescriptions, dental work, glasses, hearing aids, therapy—if you paid for it and it’s medical, it likely qualifies. You need to exceed 15% of your net income to claim, but if you do, the deduction is substantial.
- Charitable Donations: Don’t just donate; get a receipt. Donations give you a tax credit (not a deduction), which is often more valuable.
- Tuition and Education: If you or your spouse/children paid for eligible education, claim it. Unused credits can be transferred.
- Childcare and Daycare: If you paid for childcare to allow you to work, study, or conduct business, it’s deductible. Keep receipts.
- Investment Losses: If you had investment losses in 2024, you can use them to offset capital gains. If you have no gains, you can carry losses back three years or forward indefinitely.
The key here: don’t guess. If you think something might be deductible, check the CRA’s official deductions and credits page or ask a tax professional. The penalty for claiming something you shouldn’t is far worse than missing a deduction.

Self-Employed? Here’s Your Last-Minute Checklist
If you’re self-employed, the last day for taxes Canada is even more critical because your filing is more complex. Here’s what you need to do:
- Calculate Your Net Business Income: Add up all income from your business. Subtract all legitimate business expenses (supplies, equipment, rent, utilities, professional fees, advertising). The result is your net income—this is what gets taxed.
- Track Quarterly Estimated Tax Payments: If you owe more than $3,000 in taxes and $3,000 in provincial tax (combined), you need to make quarterly installments. Missing these triggers penalties. Check if you’re required to make estimated tax payments (while this link references California, the principle applies across Canada—contact CRA for your province’s rules).
- Gather All Receipts: Every business expense needs documentation. Mileage logs for vehicle use, credit card statements, invoices, bank statements—everything. The CRA loves auditing self-employed people, so be thorough.
- Separate Personal and Business: If you’ve mixed personal and business expenses, untangle them now. You can only deduct business expenses, not personal ones.
- Consider Installments for Next Year: If you’re going to owe $3,000+ again next year, the CRA might require installments. Plan ahead.
- Claim Home Office Properly: If you have a dedicated workspace, calculate the square footage and claim a proportional share of rent/mortgage interest, utilities, and property tax.
- Review Deductible Vehicle Expenses: If you use a vehicle for business, track mileage and expenses. Keep a log. The CRA is strict about this.
Self-employed filers often benefit from working with a tax professional, especially as the last day for taxes Canada approaches. The cost of an accountant ($500-$1,500) is often far less than the penalties and interest from mistakes.
Filing Options When Time Is Running Out
You’ve got options for filing as the last day for taxes Canada approaches. Choose based on your situation:
- File Online (NETFILE): This is the fastest option. You can file electronically through CRA-certified software or a tax professional. Returns are processed in 2-3 weeks. Most people should do this.
- Hire a Tax Professional: An accountant or tax preparer can file on your behalf. They handle everything, including finding deductions you missed. Cost is $200-$1,000+ depending on complexity, but it’s often worth it for peace of mind.
- Use Tax Software: Programs like UFile, StudioTax, or TurboTax guide you through the process. They cost $20-$150 depending on complexity. Good option if your taxes are straightforward.
- Paper Return: You can still file on paper, but it takes longer to process (8+ weeks) and you’re more likely to make errors. Avoid this unless you have no other option.
Here’s the reality: if you’re close to the last day for taxes Canada and your taxes are complex, hire a professional. It costs money upfront, but it prevents costly mistakes and ensures you claim everything you’re entitled to.
What Happens If You Miss the Deadline
Let’s be clear about the consequences of missing the last day for taxes Canada:
- Late-Filing Penalty: 5% of unpaid taxes plus 1% for each full month late (maximum 12 months = 17% penalty). If you owe $5,000, that’s a $250-$850 penalty depending on how late you are.
- Compound Interest: The CRA charges daily compound interest on unpaid amounts. At 10% annually, $5,000 becomes $5,500 after one year.
- Loss of Refund: If you’re owed a refund and file late, you lose interest the CRA would have paid you. It’s not a penalty, but it’s lost money.
- Increased Audit Risk: Filing consistently late raises red flags. The CRA is more likely to audit you, which means scrutinizing every deduction and expense.
- Collection Action: If you owe a large amount and don’t file or pay, the CRA can garnish your wages, freeze your bank accounts, or place a lien on your property.
- Loss of Benefits: If you claim Canada Child Benefit, GST/HST credit, or other benefits, late filing can delay or suspend payments.
The bottom line: missing the last day for taxes Canada costs real money and creates real problems. It’s not worth it.
Common Last-Minute Filing Mistakes to Avoid
When you’re rushing to file before the last day for taxes Canada, mistakes happen. Here are the ones that cost people the most:
- Wrong Social Insurance Number (SIN): Double-check your SIN and your spouse’s SIN. A typo here delays processing and can cause serious issues.
- Forgetting Spousal Income: If you’re married or in a common-law relationship, you both need to file. Forgetting one person’s return is a red flag for the CRA.
- Claiming Deductions Without Documentation: The CRA asks for proof. If you claim $5,000 in home office expenses but have no receipts, you’ll lose the deduction and face penalties if audited.
- Misreporting Investment Income: The CRA receives copies of T5 slips directly from financial institutions. If your return doesn’t match, you’re getting audited. Report everything, even small amounts.
- Forgetting to Report All Income: Cash income, side gigs, freelance work—it all needs to be reported. The CRA has ways of finding out.
- Claiming Business Losses Without a Real Business: If you claim your hobby as a business and report losses year after year, the CRA will challenge it. A real business is operated with the intention of making a profit.
- Not Keeping Receipts: The CRA can ask for supporting documents up to six years after filing. If you can’t produce them, you lose the deduction.
- Filing Jointly When You Shouldn’t: Some deductions and credits can’t be split between spouses. Make sure you’re claiming things correctly.
- Forgetting to Sign Your Return: A return without a signature isn’t valid. Seems simple, but it happens.
- Missing the Deadline by One Day: June 15th at 11:59 PM is the cutoff. One day late, and you’re subject to penalties. File early to avoid this.
Warning: The CRA’s audit selection process includes computer matching against T4s, T5s, and other slips. If your return doesn’t match what employers and institutions report, you’re getting audited. Be accurate and complete.
If you’re unsure about something on your return, it’s better to ask a tax professional than guess. The cost of a quick consultation ($50-$100) is far less than the cost of an audit or reassessment.

Frequently Asked Questions
What is the exact last day for taxes Canada in 2025?
– The last day for taxes Canada in 2025 is June 15, 2025, for filing your 2024 tax return. However, any taxes you owe are due by April 30, 2025. The CRA doesn’t grant extensions, so mark both dates in your calendar.
Can I file my taxes after June 15th without penalties?
– No. If you file after June 15th and owe taxes, you’ll face a late-filing penalty of 5% of the unpaid balance plus 1% for each full month late (up to 12 months). You’ll also owe compound interest on any unpaid amount. If you’re expecting a refund, filing late just delays your money.
What happens if I can’t pay my taxes by April 30th?
– Contact the CRA immediately. They offer payment arrangements and installment plans if you can’t pay in full. It’s far better to work with them proactively than to ignore the debt. Ignoring it triggers collection action, including wage garnishment and bank account freezes.
Do I need to file if I didn’t earn much income?
– Even if you earned little or no income, you should file if you received any government benefits, paid into CPP/EI, or had taxes withheld. Filing ensures you get any refunds or benefits you’re entitled to. Plus, filing maintains your eligibility for future benefits.
Is hiring a tax professional worth the cost?
– Yes, especially if your taxes are complex (self-employed, multiple income sources, rental properties, investments). A professional often finds deductions you missed, which pays for their fee many times over. Plus, they reduce audit risk by ensuring accuracy.
What if I lost my T4 or other tax documents?
– Contact your employer or the institution that issued the slip immediately. They can provide a duplicate. The CRA also maintains records, so you can request a copy directly from them. Don’t file without these documents—your return will be incomplete.
Can I file my taxes before the deadline?
– Absolutely. In fact, you should. Filing early means getting your refund faster and avoiding the stress of last-minute filing. There’s no downside to filing early.
What deductions can I claim if I worked from home?
– You can claim a portion of rent/mortgage interest, utilities, internet, property tax, and supplies. Use either the simplified method ($2 per square foot, up to 300 sq ft) or calculate actual expenses. Keep receipts for everything.
Will the CRA audit me if I file late?
– Filing late increases your audit risk. The CRA flags consistently late filers, and late filing is a red flag for potential issues. Even if you’re not audited, the penalties and interest make late filing expensive.
How long does the CRA take to process my return?
– If you file electronically (NETFILE), processing takes 2-3 weeks. Paper returns take 8+ weeks. The CRA processes returns in the order they’re received, so filing early gets you processed faster.
