While working from home in 2025, you’ve probably noticed a couple of things right away. One, your daily commute is now the eight steps from the bedroom to your desk (or kitchen table). Two, your utility bills, internet costs, and maybe even your coffee consumption have quietly crept higher. Here’s the bright side: the CRA recognizes that working from home comes with real expenses, and you may be eligible for work from home tax deductions in Canada for 2025. That means you could lower your taxable income while claiming a portion of the costs for your home office, internet, utilities, and even some office supplies. The catch? The rules can be tricky, and claiming something you’re not entitled to could mean headaches down the line, audits, reassessments, or extra paperwork.
Here’s what you’ll learn:
- Who qualifies for work-from-home tax deductions in Canada for 2025
- Which expenses can you claim (and which you can’t)
- How to choose between the detailed method and the flat rate method
- Common mistakes to avoid and tips to maximize your refund
Let’s make sure you keep more of your hard-earned money, without raising any red flags with the CRA.
Who Qualifies for Work-from-Home Tax Deductions Canada 2025
The CRA doesn’t just hand these deductions out to anyone with a laptop. To qualify for work-from-home tax deductions in Canada in 2025, you generally need to meet at least one of these conditions:
- You worked from home for more than 50% of your work hours for at least four consecutive weeks in the year.
- You’re required to use your home as your principal place of work because your employer doesn’t provide you with an office.
- You’re self-employed and your home office is your main business location.
If you’re an employee, you’ll usually need a signed T2200 form (Declaration of Conditions of Employment) from your employer to claim certain expenses.
One big change since the pandemic years: the temporary flat rate method that let you claim $2 a day without receipts has been phased out for most taxpayers. For 2025, you’ll likely need to use the detailed method unless new CRA announcements bring it back.
What Expenses You Can Claim Under Work-from-Home Tax Deductions
This is where it gets interesting, and where people often get it wrong.
Direct Expenses
These are costs that are 100% related to your home office. If you bought an ergonomic chair, a desk, a desk lamp, or a webcam specifically for work, you can generally claim the full amount (or depreciate it if it’s capital equipment).
Pro-Rated Expenses
This is where you take shared household costs and claim only the portion used for work. Examples include:
- Electricity and heating
- Internet service
- Water
- Rent (if you’re a tenant)
If your home office is 10% of your home’s square footage, you can usually claim 10% of these costs.
Employee-Specific Items
If you’re not self-employed, your eligible list is shorter. Think consumables: printer ink, pens, paper, and postage.
Self-Employed Extras
If you run your own business, you can also claim a portion of property taxes, mortgage interest, and home insurance.
Remember: The CRA expects you to be reasonable. Claiming half your home’s square footage as an office when you actually work from the dining table is a red flag
CRA Methods for Claiming Work-from-Home Deductions in 2025
So, how do you actually calculate these deductions? The CRA offers two main methods.
1. Detailed Method
This is the one most people use in 2025. You keep receipts, calculate the exact proportion of your home used for work, and claim the eligible portion of each expense.
- Pros: Can result in a larger deduction if you have significant home-related expenses.
- Cons: More record-keeping, and you’ll need to prorate everything.
Example:
If your apartment is 1,000 sq. ft. and your home office is 100 sq. ft., that’s 10%. If you paid $2,400 in electricity for the year, you could claim $240.
2. Flat Rate Method
Previously, during the pandemic, you could claim a set daily amount without receipts. For 2025, check the CRA’s updates, but as of now, it’s not widely available except in special cases.
Common Mistakes to Avoid When Claiming Work-from-Home Deductions
Even well-meaning taxpayers can stumble here.
- Over-claiming expenses: Claiming your entire internet bill or hydro bill without prorating.
- Including non-eligible costs: Furniture that doubles as personal use, home renovations, or your daily cappuccino machine.
- Not keeping receipts: The CRA can audit you and request proof for up to 6 years after you file.
- Forgetting to adjust for shared spaces: If your office doubles as a guest room, you need to factor in that it’s not 100% work use.
Think of it this way: If you wouldn’t explain the expense with a straight face to a CRA agent, it probably doesn’t belong on your return.

- Measure your workspace accurately: Square footage is key for prorating.
- Use CRA’s online calculator: It takes the guesswork out of the math.
