Tax Tips for Canadians With Debt: Deductions and Credits You’re Missing

Mar 20, 202622 min read

The Tax-Debt Connection Most Canadians Overlook

Every spring, millions of Canadians file their tax returns with a singular focus: “How much do I owe?” or “How much am I getting back?” What most fail to realize is that tax filing is one of the most powerful financial tools available to Canadians managing debt. The right deductions and credits can put hundreds or even thousands of dollars back in your pocket — money that can go directly toward debt repayment, emergency savings, or rebuilding your financial life.

Yet a staggering number of Canadians leave money on the table. The Canada Revenue Agency (CRA) estimates that approximately 12% of eligible Canadians do not file their tax returns at all, forfeiting benefits like the GST/HST credit, Canada Child Benefit, and the Canada Workers Benefit. Among those who do file, many miss legitimate deductions because they do not know they exist, do not keep adequate records, or cannot afford professional tax preparation.

This guide is specifically designed for Canadians who are dealing with debt — whether credit card balances, student loans, consumer proposals, or CRA tax debt itself. We will cover every deduction and credit that may apply to your situation, explain how to deal with the CRA when you owe money, and connect you with free tax preparation services that can help you claim every dollar you deserve.

Tax Credits vs. Tax Deductions: Understanding the Difference

Before diving into specific tax benefits, it is essential to understand the difference between a tax credit and a tax deduction — they work differently and have different impacts on your bottom line.

For Canadians with debt, refundable tax credits are particularly valuable because they pay out regardless of how much tax you owe. Even if your income is very low, you receive the full benefit.

Deductions That Reduce Your Taxable Income

1. Moving Expenses (Line 21900)

If you moved at least 40 kilometres closer to a new job, business, or full-time educational institution in Canada, you can deduct your moving expenses against income earned at the new location. Eligible expenses include:

Transportation and travel costs for you and your family (fuel, meals, accommodation en route). Temporary living expenses near your old or new home for up to 15 days ($51/meal simplified method, or actual receipts). Cost of cancelling a lease at your old home. Legal fees and transfer taxes if you sold your old home. Cost of connecting and disconnecting utilities. Storage costs during the move.

For a Canadian who moved from Halifax to Toronto for work, typical deductible moving expenses might total $3,000-$8,000. At a 30% marginal tax rate, this translates to $900-$2,400 in tax savings — money that can go directly toward debt repayment.

If your income at the new location is not enough to fully deduct your moving expenses in the year of the move, you can carry the unused portion forward to the next year. This is particularly valuable for students who move for post-secondary education — you can deduct moving expenses against scholarships, bursaries, and research grants in the year of the move, and carry forward any excess to future years when you have employment income.

2. Interest Deductibility (Line 22100)

This is one of the most misunderstood areas of Canadian tax law. Interest on money borrowed for personal purposes — credit cards, personal loans, car loans — is NOT tax-deductible. However, interest on money borrowed for the purpose of earning investment income IS deductible.

This means:

Deductible: Interest on a loan used to buy stocks, bonds, mutual funds, or rental property. Interest on a line of credit used for business purposes. Carrying charges and interest expenses on your investment account.

NOT Deductible: Credit card interest on personal purchases. Interest on your car loan (unless the car is used for business). Mortgage interest on your principal residence (unlike the United States, Canada does not allow mortgage interest deductions on primary homes).

For Canadians with investment loans, this deduction can be significant. If you have a $50,000 investment loan at 6% interest, your annual interest cost is $3,000 — all of which is deductible against your investment income (and potentially other income).

3. RRSP Contributions (Line 20800)

Registered Retirement Savings Plan contributions are one of the most powerful tax deductions available to Canadians. Every dollar you contribute reduces your taxable income by one dollar. The 2025 contribution limit is 18% of your previous year’s earned income, up to a maximum of $31,560, minus any pension adjustments.

For Canadians with debt, RRSP contributions create a strategic opportunity: contribute to your RRSP, receive a tax refund, and use that refund to pay down high-interest debt. For example, a Canadian in the 30% marginal tax bracket who contributes $5,000 to an RRSP receives approximately $1,500 in tax savings — enough to make a meaningful dent in credit card debt.

4. Childcare Expenses (Line 21400)

If you pay for childcare so that you or your spouse can work, run a business, or attend school, you can deduct childcare expenses. The maximum deduction depends on the child’s age:

Eligible childcare providers include licensed daycare centres, before-and-after school programs, day camps (but not overnight camps, which have a weekly limit), nannies, and babysitters. Keep all receipts, and note that the deduction is generally claimed by the lower-income spouse.

5. Union and Professional Dues (Line 21200)

If you pay union dues, professional membership fees required for your employment, or liability insurance premiums required by your profession, these are fully deductible. For Canadians in unionized jobs, this can mean deductions of $500-$1,500/year. Professional dues for accountants, engineers, nurses, teachers, and other regulated professions are also deductible.

Tax Credits That Reduce Your Tax Bill

1. Medical Expenses (Line 33099 / 33199)

The medical expense tax credit is one of the most valuable — and most frequently under-claimed — credits available to Canadians. You can claim eligible medical expenses that exceed 3% of your net income or $2,759 (whichever is less) for the 2024 tax year.

Eligible medical expenses include far more than most Canadians realize:

Commonly claimed: Prescription medications, dental work (crowns, root canals, braces, dentures), eyeglasses and contact lenses, hearing aids, crutches, wheelchairs, and medical travel costs.

Frequently missed: Premiums for private health insurance (Blue Cross, Manulife, Sun Life), therapy and counselling (psychologist, social worker, occupational therapist), fertility treatments (IVF can cost $10,000-$15,000 per cycle), service animal costs, air conditioning (if prescribed for a chronic condition), home modifications for medical accessibility, and travel expenses to access medical care more than 40 km from home.

1. Gather All Medical Receipts

   Collect receipts for every medical expense paid during a 12-month period ending in the tax year. You can choose any 12-month period that ends in 2024 — it does not have to be January to December. This flexibility allows you to group larger expenses into a single claim period. Include prescriptions, dental bills, vision care, therapy, insurance premiums, and medical travel.



2. Calculate Your Threshold

   Determine 3% of your net income. If your net income is $45,000, your threshold is $1,350 (3% x $45,000). Since $1,350 is less than the $2,759 cap, you use $1,350 as your threshold. Only expenses above this threshold generate a tax credit.



3. Claim on the Lower-Income Spouse's Return

   Medical expenses should generally be claimed by the lower-income spouse. Because the threshold is based on 3% of net income, a lower income means a lower threshold, which means more expenses qualify for the credit. If one spouse earns $40,000 and the other earns $80,000, claiming on the $40,000 income return results in a lower threshold ($1,200 vs. $2,400).



4. Calculate Your Credit

   Subtract your threshold from your total eligible expenses and multiply by 15% (the federal credit rate). Provincial credits provide additional savings. For example: $5,000 in medical expenses minus $1,350 threshold = $3,650 eligible amount x 15% = $547.50 federal credit, plus provincial credit.

2. Disability Tax Credit (Line 31600 / 31800)

The Disability Tax Credit (DTC) is worth approximately $1,400-$2,400 per year in federal tax savings alone (more with provincial credits), yet it is significantly under-claimed. The CRA estimates that hundreds of thousands of eligible Canadians do not receive the DTC because they never apply.

The DTC is not limited to visible disabilities. Eligibility extends to Canadians with diabetes (Type 1 requiring insulin and monitoring), mental health conditions that markedly restrict daily functioning, chronic pain conditions, learning disabilities, speech impairments, and many other conditions that substantially limit basic activities of daily living.

To apply, you need Form T2201 — Disability Tax Credit Certificate — completed by a qualified medical practitioner. The form requires the practitioner to certify that your impairment is severe and prolonged (lasting at least 12 months). If approved, you can claim the credit retroactively for up to 10 years, potentially resulting in a lump-sum refund of $14,000-$24,000.

Qualifying for the Disability Tax Credit unlocks access to several other programs: the Registered Disability Savings Plan (RDSP) with up to $3,500/year in government matching grants, the Canada Workers Benefit disability supplement (additional $737), the child disability benefit (up to $3,173/year per child), and the ability to claim attendant care expenses. If you or a family member has a disability, the DTC application should be your top tax priority — its cascading benefits can total $5,000-$10,000+ per year.

3. Canada Workers Benefit (Schedule 6)

The Canada Workers Benefit (CWB) is a refundable tax credit — meaning it pays out even if you owe no tax. It is designed for low-income working Canadians and is one of the most impactful credits available.

For the 2024 tax year, the maximum CWB is $1,518 for single individuals and $2,616 for families. The credit begins to phase in when earned income exceeds $3,000 and phases out at higher income levels (approximately $23,000 for singles and $26,500 for families). An additional disability supplement of up to $737 is available if you qualify for the DTC.

Critically, the CWB now includes advance payments — eligible Canadians can receive 50% of their estimated CWB in quarterly installments throughout the year, rather than waiting until tax filing. This provides immediate cash flow for debt payments or emergency savings.

4. Tuition Tax Credit (Line 32300)

If you or your children attend a qualifying post-secondary institution in Canada, tuition fees generate a non-refundable tax credit at 15% of the amount. There is no maximum. A student paying $8,000/year in tuition receives a federal credit of $1,200. Unused tuition credits can be carried forward indefinitely or transferred (up to $5,000) to a spouse, parent, or grandparent.

For Canadians repaying student loans while also attending school, this credit can significantly reduce your tax burden — freeing up cash flow for loan payments.

5. Interest Paid on Student Loans (Line 31900)

Interest paid on qualifying student loans (Canada Student Loans, provincial student loans, and apprenticeship loans) is eligible for a non-refundable tax credit. Note that interest on federal Canada Student Loans has been permanently eliminated as of 2023, but provincial loan interest may still apply. You can claim interest paid in the current year or carry it forward for up to five years.

6. Donations and Charitable Gifts (Line 34900)

Charitable donations generate a non-refundable tax credit. The first $200 of donations earns a 15% federal credit ($30), and amounts above $200 earn a 29% federal credit (or 33% for donors in the top tax bracket). With provincial credits added, the combined credit on donations above $200 can reach 40-50% depending on your province.

For Canadians with debt, this may seem irrelevant — but if you are already donating to a place of worship, charity, or community organization, make sure you are claiming the credit. Even $500/year in donations generates approximately $130 in tax credits.

Dealing With CRA Tax Debt

If you owe money to the CRA — whether from an unexpected tax bill, unfiled returns, or a reassessment — ignoring it is the worst possible strategy. CRA charges compound daily interest on unpaid balances at a prescribed rate (currently around 10% annually), and has powerful collection tools including garnishing wages, freezing bank accounts, and placing liens on property.

However, CRA also offers several programs to help Canadians manage tax debt:

CRA Payment Arrangements

You can call the CRA at 1-888-863-8662 to negotiate a payment arrangement. The CRA will work with you to set up a monthly payment plan based on your ability to pay. While interest continues to accrue, the CRA will generally not take enforcement action (wage garnishment, bank freezes) while you are making agreed-upon payments.

Taxpayer Relief Provisions

Under the Taxpayer Relief Provisions (formerly the Fairness Program), the CRA can cancel or waive penalties and interest in certain circumstances:

Extraordinary circumstances: Natural disasters, serious illness, emotional or mental distress, civil disturbances. If you could not file on time or make payments due to circumstances beyond your control, the CRA may forgive penalties and interest.

CRA errors: If incorrect information from the CRA caused you to miss a deadline or make an incorrect filing, penalties may be waived.

Financial hardship: If paying the full amount would cause undue financial hardship, the CRA may agree to reduced payments or interest relief.

To apply, complete Form RC4288 — Request for Taxpayer Relief. Include a detailed explanation and supporting documentation. The CRA considers requests for up to 10 prior calendar years.

CRA and Insolvency

If your tax debt is overwhelming, know that CRA debt can be included in a consumer proposal or bankruptcy filing. A Licensed Insolvency Trustee can negotiate with the CRA on your behalf. In a consumer proposal, CRA must accept the same terms as other unsecured creditors — typically settling for 20-30 cents on the dollar. This can be the most effective way to resolve large tax debts that you cannot realistically repay in full.

If you receive a letter from the CRA, open it immediately and respond by the deadline. Ignoring CRA notices can escalate your situation rapidly. The CRA has the legal authority to garnish your wages without a court order, freeze your bank accounts, seize assets, and register liens against your property. None of this happens if you communicate with them and set up a payment arrangement. The CRA is surprisingly reasonable when you are proactive — and extremely aggressive when you are not.

Special Tax Situations for Canadians With Debt

Northern Residents Deductions (Line 25500)

If you live in a prescribed northern or intermediate zone for at least six consecutive months, you may be eligible for the Northern Residents Deductions. The residency deduction provides up to $22 per day ($11 per day for intermediate zones). For a full year in a prescribed northern zone, this translates to a deduction of up to $8,030 — which at a 30% marginal tax rate saves approximately $2,409 in taxes. A travel deduction is also available for up to two trips per year to the nearest city with a population of at least 200,000.

Home Office Expenses

If you work from home — whether as an employee or self-employed — you may deduct a portion of your home expenses. Eligible expenses include a proportionate share of rent, utilities, internet, home insurance, and maintenance costs. The simplified method (available for employees) allows a deduction of $2/day up to $500/year without receipts. The detailed method requires Form T2200 from your employer and can result in larger deductions based on the percentage of your home used for work.

Self-Employment Tax Deductions

Self-employed Canadians have access to a broader range of deductions, including business-use-of-home expenses, vehicle expenses (proportionate to business use), office supplies, professional development, business insurance, advertising costs, and meals and entertainment (50% deductible). If you have a side hustle generating income, ensure you are claiming all legitimate business expenses to reduce your net self-employment income — and thus your tax burden and CPP contributions.

Free Tax Preparation: The CVITP Program

The Community Volunteer Income Tax Program (CVITP) is one of Canada’s best-kept secrets. Funded by the CRA, CVITP provides free tax return preparation for Canadians with modest incomes and simple tax situations. Over 3,000 tax clinics operate across Canada during tax season, staffed by trained volunteers.

Who Qualifies for CVITP

To find a CVITP clinic near you, visit canada.ca/taxes-help or call 1-800-959-8281. Many clinics offer both in-person and virtual appointments. Some operate year-round, not just during tax season. If you have unfiled returns from previous years, CVITP volunteers can often prepare those as well — helping you catch up and start receiving benefits you have been missing.

Filing Past-Due Tax Returns

If you have not filed tax returns for one or more years, you are not alone — and it is never too late to file. Filing late returns is critical because:

You may be owed money: Many Canadians with low income are owed refunds they have never claimed, plus years of GST/HST credits, Canada Child Benefits, and provincial benefits.

Penalties grow: Late filing penalties start at 5% of the balance owing plus 1% per month (up to 12 months). Repeat late filers face even steeper penalties — 10% plus 2% per month.

Benefits stop: The CRA suspends GST/HST credit and CCB payments if you do not file. Filing your return immediately reactivates these benefits.

1. Gather Available Documentation

   Collect any T4 slips, T5 slips, RRSP contribution receipts, and other tax documents you have. If you are missing documents, you can access them through your CRA My Account online portal (if you have access) or request copies from the CRA by calling 1-800-959-8281. Employers and financial institutions are required to keep records for at least six years.



2. Use Free Tax Software

   Even for past years, free tax software like Wealthsimple Tax (formerly SimpleTax), TurboTax Free, or StudioTax can prepare prior-year returns. CVITP clinics can also prepare past-due returns. The CRA’s NETFILE service accepts electronic filing for the current year and up to four prior years.



3. File and Apply for Relief

   Submit your returns. If you owe money and penalties, file the Taxpayer Relief form (RC4288) simultaneously, explaining your circumstances and requesting penalty and interest relief. The CRA considers relief requests for up to 10 prior years. Even if relief is not granted, you have now stopped the clock on further penalties and can negotiate a payment plan.

Tax Strategies for Different Debt Situations

Credit Card Debt

Credit card interest is not tax-deductible, but you can use tax strategies to generate cash for repayment. Maximize RRSP contributions to generate a tax refund, then apply the entire refund to your highest-interest credit card. Claim every eligible deduction and credit to increase your refund. Consider whether contributing to a TFSA (no tax deduction but tax-free growth) or RRSP (tax deduction now, taxed later) makes more sense given your current tax bracket and debt situation.

Student Loan Debt

Interest on federal and provincial student loans is eligible for a non-refundable tax credit. Unused interest can be carried forward for up to five years. While federal student loan interest has been eliminated, provincial loan interest still applies in most provinces. Tuition credits from your study years can be carried forward indefinitely and applied to reduce your tax bill now — freeing up cash for loan payments.

Consumer Proposal or Bankruptcy

If you have filed a consumer proposal or gone through bankruptcy, your tax situation has specific considerations. In the year of bankruptcy, you will have two tax returns — a pre-bankruptcy return and a post-bankruptcy return. Your Licensed Insolvency Trustee will prepare the pre-bankruptcy return. Any tax refund from the pre-bankruptcy period belongs to the estate (creditors), but post-bankruptcy refunds are yours. RRSP contributions made more than 12 months before bankruptcy are protected from creditors — another reason to contribute regularly.

CRA Tax Debt Combined With Other Debt

If you owe money to both the CRA and private creditors, prioritize the CRA. Unlike other creditors, the CRA can garnish your wages and freeze your accounts without going to court. Set up a payment arrangement immediately and redirect your tax refund to the CRA balance. If total debts are unmanageable, consult a Licensed Insolvency Trustee — CRA debt can be included in a consumer proposal alongside other unsecured debts.

Provincial Tax Credits and Benefits

Beyond federal credits, each province offers additional tax credits that Canadians with debt should claim:

Frequently Asked Questions

Your Tax Action Plan

Tax season is not something to dread — it is an opportunity to put money back in your pocket. Here is your action plan:

Immediately: If you have unfiled tax returns, file them now. Every day without filing is a day without GST/HST credits, CCB payments, and other benefits you are entitled to. Use Wealthsimple Tax (free) or visit a CVITP clinic.

Before Filing: Review the deductions and credits in this guide. Gather all medical receipts, childcare receipts, moving expense documentation, and charitable donation receipts. Check your CRA My Account for T4 slips and contribution room.

After Filing: Direct your tax refund to your highest-priority financial goal — whether that is paying off high-interest credit card debt, building an emergency fund, or settling a CRA balance. Do not treat your refund as a windfall to spend.

Year-Round: Keep a folder (physical or digital) for tax-related receipts throughout the year. Track medical expenses, charitable donations, and any work-from-home days. When tax season arrives, you will be prepared — and you will not miss a single dollar you are entitled to.

Every dollar you save on taxes is a dollar that can go toward eliminating debt and building financial freedom. Claim what is yours.
