Tax season is here, and many people are asking the same thing: “How can I pay less tax?”

The answer often comes down to understanding two powerful tax tools—deductions and credits. Both reduce how much tax you owe, but they work in very different ways. Knowing the difference can lead to real savings.

 

Tax Deductions: Reducing Your Taxable Income

Every dollar you deduct lowers your taxable income. The value of a tax deduction depends entirely on your marginal tax rate—the rate applied to your next dollar of income.

 

Here’s How It Works:

Let’s say you earn $100,000 and make a $10,000 RRSP contribution. That contribution is a tax deduction, reducing your taxable income to $90,000. If you’re in a 43% marginal tax bracket in Ontario, that $10,000 deduction saves you approximately $4,300 in taxes.

 

Key takeaway: Deductions are more valuable when your income—and tax bracket—is higher.

 

Common Tax Deductions Include:

• RRSP deduction – reduce taxable income while boosting retirement savings
• FHSA deduction – reduce taxable income while saving for a first home
• Childcare expenses— claim costs for daycare, or afterschool care required so you can work.
• Support Payments – deductible if paid under a court order or written agreement.
• Pension Income Splitting – split eligible pension income with a spouse or common-law partner
• Union or professional dues— claim required fees related to your occupation.
• Moving expenses— deductible if you move at least 40 km closer to work or school.
• Investment carrying charges and interest— claim certain costs tied to earning investment income.
• Business or employment expenses— deductible if you’re self-employed or meet CRA criteria

 

Planning Tip: If you’re self-employed or have investment income, tracking deductible expenses throughout the year can make a significant difference. Keep organized records and consider working with a tax professional to ensure you’re claiming everything you’re entitled to.

 

Tax Credits: Direct Reductions to What You Owe

Instead of lowering your taxable income, tax credits lower your tax bill. Most credits are non‑refundable, meaning they can reduce your tax to zero but won’t create a refund beyond that.

 

Here’s how it works:

An Ontario resident earning $100,000 pays roughly $21,000 in income tax. If they incur $10,000 in eligible medical expenses, they’ll receive approximately $1,400 in medical expense tax credits, lowering total tax owing to $19,600.

 

Note: Most federal non-refundable tax credits are calculated at the lowest federal rate (14.5% for 2025 and 14% for subsequent years). Since the federal lowest personal tax rate was reduced in 2025, the new non-refundable top-up tax credit effectively maintains a 15% rate for non-refundable tax credits claimed if your taxable income is above $57,375. Budget 2025 outlines that the top-up tax credit will apply on a transitional basis for the 2025-2030 taxation years.

 

Common Tax Credits Include:

• Basic personal amount— lets you earn a minimum level of income taxfree.
• Age amount— available if you’re 65+ with income below set thresholds.
• Canada caregiver amount— for supporting dependents with impairments.
• Disability tax credit—for individuals with severe and prolonged impairments
• Medical expenses—claim eligible expenses above $2,759 or 3% of your net income, whichever is less
• Charitable donations—15% on the first $200, then 29% (or higher in some provinces) on amounts above that
• Tuition credits—claim eligible post-secondary tuition fees
• Interest paid on student loans – claim interest from government student loans (current year + previous 5 years).
• First-time home buyers’ credit—$10,000 credit for eligible first-time homeowners
• Canada training credit—up to $250/year for eligible course fees
• Eligible educator school supply tax credit – teachers and early childhood educators can claim up to $1,000 for eligible school supplies expenses
• Adoption expenses – claim eligible adoptionrelated costs

 

Some credits—like the GST/HST credit and Canada Child Benefit—are refundable, meaning you may receive them even if you owe no tax. These depend on income level.

 

Tax Planning Opportunities

There are several valuable opportunities to optimize your tax position by carrying certain deductions and credits forward to future years or back to prior ones. For example:

 

• RRSP and FHSA deductions can be deferred and used strategically in higherincome years.
• Capital losses can offset capital gains, with unused amounts carried back up to three years or carried forward indefinitely.
• Charitable donations may be claimed up to 75% of net income annually, and any unused portion can be carried forward for up to five years.

 

Beyond carryforward rules, many taxpayers miss another powerful planning tool: credit transfers within a family. If a family member has credits they can’t fully use—often because their income is too low or they owe little to no tax—the unused portion can often be transferred to someone who can benefit. Transfers are completed directly on the tax return; no separate filing is needed. The key is planning together to ensure that only one person claims each transferable credit.

 

Transferable Credits Include:

1. Spousal Transfers
   • Age amount
   • Pension income amount
   • Disability amount
    
2. Tuition Credits

Students can transfer up to $5,000 of their currentyear federal tuition amount—minus the portion they need to reduce their own tax owing—to one eligible person (parent, grandparent, spouse, or common‑law partner). Any remaining amount can be carried forward to reduce the student’s taxes in future years.

 
3. Disability Tax Credit (DTC)

If someone qualifies for the Disability Tax Credit (DTC) but doesn’t need all of the credit, the unused portion may be transferred to a supporting family member. This is especially valuable for parents of children with disabilities or adults caring for aging parents.
