How much of your income are you actually keeping?
The CRA does not send a notice when you miss a legal deduction. There is no correction letter, no audit for underclaiming. You file, pay more than required, and move on. For most Canadian households, the gap between what they actually owe and what they legally could owe runs between $500 and $4,000 annually — not from any error, but from not using the accounts and deductions the tax code quietly rewards.
This breaks down the registered accounts, commonly missed deductions, and timing decisions that move the number on your Notice of Assessment. These apply to salaried employees, freelancers, and incorporated business owners alike.
RRSP, TFSA, and FHSA: How Each Account Changes Your Tax Bill
These three registered accounts cover the majority of what most Canadians need for tax-efficient saving. They are not interchangeable. Using the wrong one for your situation costs real money.
| Account | Annual Limit (2026) | Contribution Deductible? | Growth Taxed? | Withdrawal Taxed? | Best Use Case |
|---|---|---|---|---|---|
| RRSP | 18% of prior-year earned income, max ~$32,490 | Yes — reduces taxable income immediately | No (deferred) | Yes — taxed as income | Reducing taxes in high-income years; retirement savings |
| TFSA | $7,000 | No | No | No | Tax-free growth; accessible emergency or investment savings |
| FHSA | $8,000 (lifetime max $40,000) | Yes — reduces taxable income immediately | No | No (for qualifying first home purchase) | First-time homebuyers building a down payment |
Why the RRSP Deduction Is Worth Understanding at Your Marginal Rate
RRSP contributions reduce your taxable income dollar for dollar. If you earned $95,000 in Ontario in 2026 and contributed $15,000, your taxable income drops to $80,000. At Ontario’s combined federal-provincial marginal rate of approximately 43.41% on income in the $75,000–$100,000 range, that contribution generates roughly $6,500 in tax savings in the filing year.
One option most people skip: you do not have to claim the RRSP deduction in the year you contribute. If you expect a higher bracket next year — a promotion, the first full year of a new contract, proceeds from selling a property — contribute now to lock in the room, and claim the deduction when the reduction is largest.
FHSA: The Account That Delivers Both a Deduction and a Tax-Free Withdrawal
The First Home Savings Account is the most advantageous registered account for eligible Canadians right now. You get an RRSP-style upfront deduction on contributions, and if you use the money for a qualifying first home purchase, the withdrawal is completely tax-free — exactly like a TFSA. No other registered account gives you both benefits simultaneously.
The $8,000 annual limit carries forward one year when unused. Someone who opened an FHSA in 2026 and contributed nothing can put in $16,000 in 2026. If you never buy a home, the balance transfers to your RRSP with no tax impact and no reduction to your existing RRSP contribution room. Either way, the upfront deduction stands.
TFSA Cumulative Room in 2026
If you were 18 or older in 2009 and have never contributed to a TFSA, your total accumulated room in 2026 exceeds $100,000. Withdrawals add back to your available room the following January 1 — pulling $20,000 out this year means that $20,000 re-opens as new room next year. Wealthsimple and EQ Bank both offer no-fee TFSA accounts, which matters because management fees compound against your returns just as returns compound for you.
Deductions That Disappear When You Don’t Claim Them

These are not obscure loopholes. They are standard CRA-listed deductions that millions of Canadians qualify for and underuse every single year.
Home Office Expenses: The T2200 Method
If your employer required you to work from home and signed a T2200 (Declaration of Conditions of Employment), you can claim the detailed method for home office expenses. This covers the proportional share of:
- Rent or mortgage interest
- Utilities — hydro, heat, water
- Internet costs
- Home maintenance and minor repairs
- Property taxes (homeowners only)
The proportion is your workspace square footage divided by total home square footage. A 200 sq ft office in a 1,200 sq ft home equals 16.7%. On $24,000 annual rent, that’s $4,008 deductible from employment income. On an $85,000 Ontario salary, reducing taxable income by $4,000 saves approximately $1,600 in combined federal-provincial tax. The flat-rate method that existed during the COVID years was simpler but far less valuable for most remote workers. If you have a T2200 and a dedicated workspace, the detailed method almost always wins.
Medical Expenses: The Threshold Calculation Most People Get Wrong
You can only claim medical expenses that exceed 3% of your net income or $2,635 — whichever is lower. On $70,000 net income, 3% equals $2,100, so $2,100 is your floor. Every eligible dollar above that generates a 15% federal tax credit plus provincial.
Three things people miss regularly:
- Claim medical expenses on the lower-income spouse’s return to access the lower threshold. A household earning $70,000 and $40,000 should claim on the $40,000 return, where the threshold is $1,200 instead of $2,100 — making substantially more eligible.
- Dental work, prescription eyewear, physiotherapy, and travel to a medical facility over 40 km all qualify under CRA guidelines.
- You can choose any 12-month period ending in the tax year, not just the calendar year. If most expenses hit in late 2026, a May 2026–April 2026 window on your 2026 return can capture more eligible costs.
Moving Expenses: The 40-Kilometre Rule
If you moved at least 40 kilometres closer to a new job, new business location, or post-secondary institution, the CRA allows you to deduct eligible moving costs from income earned at the new location. Covered expenses include rental trucks, packing supplies, vehicle and lodging costs during the move, up to 15 days of temporary accommodation, lease cancellation penalties, and real estate commission and legal fees if you sold a home. The deduction is capped by income earned at the new location in the same year — unused amounts carry forward and can be claimed the following year against income there.
The RRSP Deadline Is Not What Most People Think
The RRSP contribution deadline for the 2026 tax year is March 2, 2026. Contributions made in the first 60 days of 2026 can be applied to 2026 or saved for 2026 — your choice at filing. What matters more than the deadline: unused RRSP room carries forward indefinitely. Log into your CRA My Account and check your most recent Notice of Assessment. If you have never maximized contributions, your available room might be $40,000, $60,000, or more. That is a substantial, legal tax reduction available in any single year you decide to use it.
Self-Employed? These Deductions Change Your Effective Tax Rate

Sole proprietors and incorporated owners operate under a different deduction framework than employees. The list of allowable expenses is longer, but the CRA requires documentation — receipts, logs, and records that support every claim you make.
Business Use of Home on Form T2125
Self-employed individuals working from home can deduct a proportional share of housing costs without a T2200 or employer sign-off. Eligible expenses mirror the employment method: rent or mortgage interest, property taxes, utilities, home insurance, and repairs and maintenance. The calculation is workspace square footage divided by total home square footage, applied to each expense category.
The restriction worth knowing: you cannot use business-use-of-home deductions to create or increase a business loss. If net business income before the home deduction is $12,000 and the calculated home expenses total $6,000, you claim the full $6,000. If net income is only $4,000, you claim $4,000 and carry the remaining $2,000 forward to future years when the income is there to absorb it.
Vehicle Expenses: The Logbook Is Not Optional
Business-use vehicle costs — gas, insurance, repairs, parking, lease payments, or Capital Cost Allowance on a purchased vehicle — are deductible at the percentage of total kilometers driven for business. That percentage comes exclusively from a contemporaneous mileage logbook.
If you drove 22,000 km total and 13,200 of those were for client visits, supplier trips, or job sites, your business-use percentage is 60%. On a vehicle costing $13,000/year to own and operate, that’s $7,800 deducted from business income. The CRA disallows vehicle claims on audit when a logbook doesn’t exist. Apps like MileIQ or TripLog make real-time tracking practical enough that there’s no excuse to skip it.
CPP Contributions: The Half You Actually Get Back
Self-employed individuals pay both the employee and employer share of Canada Pension Plan contributions — approximately 11.9% of net business income between the basic exemption and the Year’s Maximum Pensionable Earnings (roughly $71,300 in 2026). The employer half of that contribution is deductible directly from income on line 22200 of your T1 return. On net business income of $60,000, your total self-employed CPP contribution runs approximately $6,750, and roughly $3,375 of that is an income deduction — not just a credit, but a full reduction of taxable income.
Private Health Services Plans for Incorporated Owners
If you operate through a corporation, a Private Health Services Plan (PHSP) allows the corporation to pay your medical, dental, and vision expenses as a fully deductible business expense. You receive those benefits tax-free personally. Providers like Olympia Benefits and Healtheo360 administer these plans specifically for small incorporated businesses. A sole shareholder paying $4,500/year in family dental and prescription costs would save approximately $1,900 in personal tax by routing those expenses through a PHSP, compared to claiming the personal medical expense credit that only applies above the 3% threshold.
Free vs. Paid Tax Software: A Direct Comparison

Is Wealthsimple Tax Actually Free?
Yes. Wealthsimple Tax (formerly SimpleTax) is free for all Canadian filers regardless of complexity — T4 employment income, self-employment reported on T2125, rental income, investment slips including T3, T5, and T5008. It supports NETFILE and handles RRSP, TFSA, FHSA, and all standard federal and provincial credits. There is an optional donation prompt at the end, not a paywall. For the majority of personal returns, Wealthsimple Tax covers everything at no cost.
When Does TurboTax Canada Justify the Price?
TurboTax Canada charges $19.99 for Standard (employment income) and $49.99 for Self-Employed, which covers T2125 returns with guided prompts for home office, vehicle, and meal deductions. The interview format makes it harder to accidentally skip eligible expenses on complex returns. H&R Block Canada’s software runs $19.99 to $34.99 and includes an optional expert review on the Premium tier — a human check before you hit submit. That’s a reasonable option for first-time self-employed filers who want confirmation without paying full CPA rates.
When Does a CPA Actually Earn the Fee?
A chartered professional accountant charges $150 to $400+ for a personal T1. That cost justifies itself when you have a corporation (T2) plus personal return to file together, when you sold a rental property or investment asset with capital gains complexity, when you have foreign income or US tax obligations, or when multiple years of returns are unfiled and you need CRA voluntary disclosure guidance. For a salaried employee with RRSP contributions, a TFSA, and a handful of T5 slips, a CPA adds minimal value over Wealthsimple Tax. The $300 you’d spend belongs in your RRSP — that’s a guaranteed after-tax return at your marginal rate.
The clearest path through the Canadian tax code starts with the FHSA if you are a first-time buyer: it is the only account that delivers both an upfront deduction and a tax-free withdrawal, and most eligible Canadians still have not opened one. After that, fill RRSP room in your highest-earning years, document every self-employment expense from the first invoice, and claim home office and medical deductions methodically each spring. The accounts exist. The deductions are legal. The only variable is whether you use them.
