Canada’s personal income tax system is one of the most significant aspects of its economic framework, designed to ensure fairness and transparency in contributing to public services.

In Canada, the responsibility for taxation is jointly shared by the federal government and the provincial and territorial legislatures.

The authority for taxation in Canada is outlined in the Constitution Act, 1867, specifically under Section 91(3), which grants the federal government the power to raise money through taxation, and Section 92(2), which provides similar powers to provincial governments for direct taxation within their jurisdictions.

Additionally, the Income Tax Act serves as the primary legislative framework governing the administration and collection of income taxes in Canada. This act outlines the rules for determining taxable income, deductions, credits, and filing requirements.

Canada’s tax system operates on a self-assessment basis, meaning individuals are required to report their income, calculate taxes owed, and file returns annually. The Canada Revenue Agency (CRA) oversees the administration of income tax laws and ensures compliance.

Dual-Level Taxation

Canada’s taxation system is divided between the federal government and the provinces or territories. This dual-level system allows governments to address local and national needs.

1. Federal Taxes: These are levied across Canada and fund national initiatives such as healthcare, national defense, and infrastructure projects.
2. Provincial/Territorial Taxes: Provinces and territories impose additional taxes tailored to their residents’ needs. For instance:
   • Alberta has a flat tax system, charging 10%.
   • Ontario applies progressive rates ranging from 5.05% to 13.16%.

Quebec stands out with its independent tax collection agency, Revenu Québec, which administers provincial taxes separately.

Changes to Canadian tax brackets in 2025

The federal income tax system operates on a progressive scale, where tax rates increase with income.

For 2025, federal tax is 15% for earnings up to $57,375; 20.5% between $57,375.01 and $114,750; and 26% between $114,750.01 and $177,882. The tax rate is 29% for earnings between $177,882.01 and $253,414, while anything more than that is taxed at 33%. 

For 2025, income tax brackets have increased by 2.7% which comes after a 4.7% increase in 2024.

According to Quinlan “You’re not paying more tax simply because of inflation, so (the adjustment) is good news for us all, even if you have the exact same amount of income in 2024 versus 2023, you will pay less tax because less is taxed at a higher rate”.

Sources of Taxable Income

Taxable income encompasses various sources, ensuring fairness and comprehensiveness in the tax system. Below are the primary sources:

• Employment and self-employment
• Pension and savings plan
• Investments
• Benefits

Employment Income:

• Employment income: It consists of amounts that you receive as salary, wages, commissions, bonuses, tips, gratuities, and honoraria including income from another country.
• Emergency Services Volunteers: If you are a volunteer (ambulance technician, firefighter, search and rescue, etc.) and receive a payment from an eligible employer (e.g., government). You can claim a $1,000 exemption for each eligible employer. Additionally, you may be eligible for a $3,000 volunteer firefighters’ or search and rescue volunteer amount. You can either claim the exemption or the VFA/SRVA, but not both.
• Security Options Benefits: If you buy securities at a discounted price through your employer, you have to report this benefit on your tax return, depending on whether your employer is a Canadian-controlled private corporation (CCPC). If not a CCPC, you may need to report the taxable benefit in the year you exercise the option. A deferral option was available for certain securities exercised before March 4, 2010.
• Wage-Loss Replacement Plan (WLRP) Income: If you received WLRP income, you only need to report the amount received minus any contributions you made to the plan, provided they haven’t been claimed in previous years.
• Clergy Members: If you received a housing allowance or utility amounts, subtract the amount before reporting on your tax return.

Selfemployment Income:

Self-employment refers to individuals who are in business for themselves, typically as sole proprietors. It can also include those who are partners in a partnership but do not operate through a corporation. Here are key characteristics of self-employment income:

• Personal Services: You perform services directly, typically on a contract or freelance basis.
• Independence: You generally work independently without an employer and have control over how, when, and where the work is performed.
• Risk and Reward: You assume the financial risk and responsibility, but also have the potential for profit based on the effort you put into your work.
• Examples: Freelancers, independent contractors, and professionals like consultants, artists, or tradespeople (e.g., electricians, plumbers).

When reporting self-employment income, you must declare all earnings from providing services or goods to clients and can deduct eligible expenses related to your work.

Pension and Saving Plans

• Old Age Security (OAS) Pension
  OAS Pension is a government-provided pension to seniors 65 and older who meet specific residency requirements. The amount of the pension depends on factors such as your income, the number of years you’ve lived in Canada, and whether you’re living in Canada or abroad.
  Taxable Income: The OAS pension is considered taxable income. The full OAS amount is subject to clawback if your income exceeds a certain threshold.
  
• CPP or QPP Benefits
  Canada Pension Plan (CPP) or Quebec Pension Plan (QPP) benefits are government-provided income for those who have worked in Canada or Quebec and contributed to these pension plans.
  Types of Benefits:
  Survivor Benefit (Box 15): Paid to the surviving spouse or common-law partner and children of a deceased person who contributed to CPP or QPP.
  Disability Benefit (Box 16): Paid to individuals who are disabled and unable to work, who have contributed to CPP/QPP.

  Annuities, PRPPs, RRIFs, and Life Income Funds: If you receive income from registered plans like an annuity, a pooled registered pension plan (PRPP), a registered retirement income fund (RRIF), or a life income fund (LIF), report this income here.
  Foreign Pensions: Pensions from foreign countries are also included in this category. You must report the income you receive from foreign sources.
  Taxable Income: Most pensions and annuities are taxable. Some plans, such as certain foreign pensions, may be eligible for tax treaty exemptions.
  
• Elected Split-Pension Amount
  This option allows married or common-law couples to split pension income for tax purposes. The primary purpose is to take advantage of lower tax rates by shifting income from a higher-income spouse to one with a lower income.
  Eligible Income for Splitting: Pension income eligible for splitting includes income from a pension plan, RRIF, or annuity.
  How It Works: You must make the election with your spouse and report the split amount. Both spouses will report a portion of the pension income on their returns.
  Taxable Income: The amount of pension income transferred is included in the calculation of both spouses’ taxable income.

  The RDSP is a government-sponsored savings plan designed to help people with disabilities save for their future. Contributions to the RDSP are not deductible, but the investment income grows tax-free.

  What’s Included: The amount withdrawn from an RDSP (including earnings) is reported as income.
  Taxable Income: Withdrawals from the RDSP are included in your taxable income. Only the portion representing the earnings and grants is taxable to the beneficiary.

  RRSP Income is the income you receive from your RRSP when you withdraw funds after retirement or when converting your RRSP to a RRIF.
  Types of RRSP Withdrawals:
  Lump-Sum Withdrawals: If you withdraw a lump sum from your RRSP, this is included in your income.
  Conversion to RRIF: When you convert your RRSP to a RRIF, the income generated by the RRIF withdrawals is taxable.
  Taxable Income: RRSP income is fully taxable when withdrawn. The tax is withheld at the time of withdrawal, but it must still be reported on your tax return.
  
• Other Income
  This category encompasses a wide variety of income types that don’t fall into the specific categories listed above. Common types include:
  Lump-Sum Payments: Any large, one-time payments you receive, not classified under specific categories like pension or employment income. Examples include payments related to an insurance settlement or severance.
  Retiring Allowance: This is a payment you receive from an employer upon retirement or termination. It could include severance, unused vacation pay, or a pension adjustment.

  Taxable Income: Most of the income reported on this line is taxable.
  
• Net Federal Supplements Paid
  The Net Federal Supplements include any federal assistance payments that you may have received under various government programs.

  • Gifts of Shares, Stock Options, and Other Capital Property: If you give away capital property such as stocks or options as a gift, it’s treated as though you sold it at fair market value. Any capital gain is taxable, but you may be eligible for certain exemptions or credits depending on the type of gift.
