Canadian Tax Planning 2026: 12 Moves Before the 2027 Filing Season

Tax planning works better before filing season than during it. If you are earning income in Canada in 2026, the return for that income will be filed in 2027. That gives you time now to organize records, check contribution room, understand which deductions or credits may apply, and avoid discovering missing documentation after the year is over.

For 2026, the CRA lists the first federal tax bracket at 14% on taxable income up to $58,523, with higher marginal rates applying above that level. Provincial or territorial tax is added separately.

This guide focuses on legitimate planning and record-keeping rather than aggressive tax strategies. Confirm personal eligibility and current amounts with the CRA or a qualified tax professional before acting.

How Many Canadians Are Leaving Money on the Table?

The Canadian tax code has built-in mechanics for the automatic withholding of taxes from paycheques, as well as optional tax deductions and refundable tax credits. When you file your taxes, some of these credits will be available without having to do anything other than filing your taxes. However, in the case of many of them, you will not be able to benefit from them without taking action to apply for them.

The problem is that your Canadian tax return does not ask you for everything you are eligible for. Instead, your tax return will only ask you for the items you have reported to your employer (or other sources) on your paycheque for withholding purposes. It does not ask questions relating to work-related moves, disability claims for your children, or first-time home buyer purchases unless you already know where to find the section of the return that contains these credits. The result is that billions of dollars in refundable credits go unclaimed each year across Canada, mostly by middle and lower-income households who need those funds the most.

Move 1: Review your RRSP contribution room before year-end

Do not guess your RRSP room. Check your latest Notice of Assessment or CRA My Account before contributing.

RRSP deductions can reduce taxable income, but the value of a deduction depends on your marginal tax rate and personal situation. If you have unused room from earlier years, it generally carries forward.

Contributions made in the first 60 days of the following year can generally be reported on the prior year’s return, but filing deadlines and deduction choices are year-specific. Confirm the CRA’s published 2026-return guidance before making a deadline-driven contribution.

Move 2: Claim the Basic Personal Amount

Every Canadian resident can claim the Basic Personal Amount, a non-refundable tax credit on a basic level of income. For the 2025 tax year, this amount is adjusted for inflation. Most tax software applies it automatically, but you should check that it appears on your return.

This credit lowers your federal tax owed. It doesn’t eliminate it, and it isn’t a cash refund on its own, but it’s important.

Move 3: Don’t Overlook Medical Expenses

Medical expenses are one of the most frequently unclaimed deductions on Canadian tax returns. The list of eligible expenses is longer than most people realize.

Eligible expenses can include prescription medications, dental work, eye exams, glasses, contacts, hearing aids, physiotherapy, ambulance services, travel for medical care over 40 kilometers away, and certain home modifications for a person with a disability.

There is a threshold: you can only claim medical expenses that exceed 3% of your net income or a set dollar amount, whichever is lower. If you had significant out-of-pocket health costs this year, it’s worth adding them up. Keep receipts for any medical spending throughout the year.

You can also select the 12-month period that gives you the best claim; it doesn’t have to follow the calendar year.

Move 4: Claim the Canada Workers Benefit If You Qualify

The Canada Workers Benefit (CWB) is a refundable tax credit aimed at lower-income working Canadians. Refundable means you can receive it as a cash payment, even if you owe no tax.

Eligibility depends on your income and province. If your working income is below certain levels, check if you qualify. Many eligible Canadians don’t claim it simply because they are unaware of its existence. Tax software usually identifies it, but only if you enter your income accurately.

Move 5: Split Pension Income With Your Spouse

If you or your spouse receives eligible pension income, you can transfer up to half of it to the lower-income spouse on your returns. This can significantly lower the family’s combined tax bill since the receiving spouse’s marginal rate may be lower.

Eligible pension income mostly includes payments from an employer-sponsored pension plan and, after age 65, RRSP annuity payments and RRIF withdrawals. CPP and OAS do not qualify for pension splitting.

Both spouses need to agree and file jointly. Tax software manages the details, but you must actively choose to use it.

Move 6: Claim Home Office Expenses If You Work From Home

If your employer requires you to work from home and you use a specific space for that work, you may be able to claim home office expenses. For 2026, the detailed method may require your employer to complete Form T2200, confirming your work-from-home need.

Claimable costs under the detailed method include a proportional share of rent, heat, electricity, and internet, based on the percentage of your home’s square footage used for work. Employees who own their homes cannot claim mortgage interest or capital cost allowance, but the other costs apply.

If you’re self-employed, home office deductions operate a bit differently and can cover more expenses. Keep your receipts and accurately calculate your workspace percentage.

Move 7: Deduct Union or Professional Dues

Union dues and fees paid to a professional association that your job requires are fully deductible. This includes law society dues, engineering association fees, and union memberships.

These are deducted on your T1, which lowers your taxable income. They’re listed on your T4 slip in box 44, making it easy to transfer correctly. Still, confirm that you’ve claimed the full amount.

Move 8: Claim the Disability Tax Credit If Eligible

The Disability Tax Credit (DTC) is a non-refundable credit available for Canadians with a severe and long-lasting physical or mental impairment. A medical professional needs to certify the impairment on CRA form T2201.

If you qualify, the DTC can greatly reduce your federal tax owed. It can also provide access to other benefits, like the Registered Disability Savings Plan (RDSP), which has important government matching contributions.

Many Canadians who qualify for the DTC have never applied. If you or a family member has a condition that significantly limits daily activities consistently, pursuing the application is worthwhile. Approval is not guaranteed, but the process is free.

Move 9: Claim Moving Expenses for Eligible Moves

If you moved at least 40 kilometers closer to a new job or school during 2026, you might be able to deduct eligible moving expenses. These expenses can include transportation costs, temporary housing, storage, and certain real estate fees.

The deduction can only be claimed against income earned at your new location, which limits how much you may use in one year. Any unused portion can carry forward to the next year.

Keep all your receipts and carefully document the distance.

Move 10: Claim Child Care Expenses in Full

Child care expenses, including daycare, licensed home daycare, day camps, and overnight camps, are deductible up to specific limits. Typically, the lower-income spouse must claim them, though some exceptions exist.

The limits depend on the child’s age and situation, with annual caps. This deduction can be significant for families with young children in paid care and is one of the larger deductions available to working parents.

Move 11: Check for the First-Time Home Buyers’ Tax Credit

If you or your spouse bought a qualifying home in 2026 and neither of you owned a home in the past four years, you could be eligible for the First-Time Home Buyers’ Tax Credit. This federal non-refundable credit is worth up to $1,500 in tax relief.

The rules have specific requirements regarding qualifying homes and your ownership history. It’s worth checking eligibility if you made a first purchase last year.

Move 12: Prepare to file on time, even if you expect to owe

For income earned in 2026, most individual returns are normally filed in 2027. The standard individual deadline is generally April 30, while self-employed filing rules differ. Confirm the CRA’s official 2027 filing calendar once it is published.

If you expect to owe tax, filing on time still matters. CRA penalties for late filing can be more expensive than simply having a balance outstanding, and payment arrangements may be available.

What this means in August 2026

The 2025 filing season is over. The useful action now is to prepare for the 2026 tax return that will be filed in 2027.

Use the remaining months of 2026 to:

• download or save receipts and supporting documents;
• review RRSP room and other registered-account records;
• track eligible employment, medical, moving, donation, and child-care expenses;
• document major life changes such as a home purchase, marriage, separation, or relocation;
• review capital gains and losses before year-end if they are relevant to your situation.

A few hours of organized record-keeping now is more useful than trying to reconstruct twelve months of activity next spring.

Common Mistake to Avoid

The most common mistake is filing too quickly without reviewing all possible credits and deductions. Many people see tax filing as just a task to finish, not as a chance to reclaim money they deserve.

A close second is not carrying forward unused deduction room. RRSP room, capital losses, and some other items carry over year after year. If you’re unsure about what you have available, check your latest CRA Notice of Assessment or log into your My Account portal on the CRA website.

Conclusion

The Canadian tax system offers legitimate deductions and credits, but the details depend on the tax year and your circumstances. Good planning means keeping records, checking official CRA information, using registered-account room carefully, and filing on time.

Use tax software, keep your receipts, and take your return seriously. It can truly make a difference in your finances.

Income earned during 2026 is reported on the 2026 tax return, which is filed in 2027. Most individual returns are normally due April 30, but confirm the official CRA filing calendar because special situations and self-employed rules can differ.

How do I find my RRSP contribution room?

Use your latest CRA Notice of Assessment or CRA My Account. Do not rely on a generic percentage or estimate because unused room carries forward and pension adjustments can affect the amount available.

What are the 2026 federal tax brackets?

CRA lists the 2026 federal brackets beginning at 14% up to $58,523 of taxable income, then 20.5%, 26%, 29%, and 33% at higher thresholds. Provincial or territorial rates apply in addition.

Should I use tax software now?

You do not need filing software in August, but you should organize the records the software will need later. When the 2027 filing season opens, use CRA-certified software appropriate for your return.

If you want to model long-term savings or opportunity-cost scenarios separately from tax filing, use the investment calculator and compound-interest calculator.
