1. Why You Should Understand Canadian Tax Terms

Canada’s tax system is complex and ever-changing. For newcomers, international students, freelancers, and employees, understanding key tax terms like T4, T5, RRSP, TFSA, CRA is crucial to:

  • Avoid mistakes in tax filing

  • Maximize deductions and tax credits

  • Protect your legal financial rights

  • Gain confidence when dealing with tax professionals or receiving letters from CRA

Let’s explore these important tax terms with TikiTax.ca.

2. CRA – What Is the Canada Revenue Agency?

CRA is the federal agency responsible for tax administration in Canada. It handles:

  • Collecting personal and business taxes

  • Distributing tax credits (e.g., GST/HST Credit, Canada Child Benefit)

  • Managing your online tax account

  • Sending notices, reviewing files, and handling tax violations

📌 Note: CRA never asks for payment via gift cards, Bitcoin, or threatens arrest. Be cautious of scams!

3. T4 – Statement of Employment Income

A T4 is a summary of your employment income issued by your employer each year (usually before Feb 28). It shows:

  • Your total earnings

  • Deductions for CPP, EI, income tax

  • Your employer’s business number and your employee details

You’ll need this slip to file your personal income tax return (T1). If you had multiple employers, you’ll get a T4 from each one.

4. T5 – Investment and Dividend Income

You’ll receive a T5 slip if you have:

  • Interest-earning savings accounts

  • Dividend income from stocks

  • Returns from GICs or investment funds

T5 reports passive income and must be included in your personal tax return.

5. RRSP – Registered Retirement Savings Plan

RRSP is a tax-deferred retirement savings account:

  • Contributions are deductible from taxable income

  • Investment growth within RRSP is tax-free until withdrawal (usually after age 60)

  • Can be used for the Home Buyers' Plan or Lifelong Learning Plan

RRSP is ideal for higher-income individuals aiming to reduce annual taxes.

6. TFSA – Tax-Free Savings Account

TFSA is a tax-free savings/investment account:

  • All earnings (interest, dividends, capital gains) are tax-free

  • Contributions are not tax-deductible like RRSP

  • Withdrawals are not considered taxable income

TFSA suits everyone—from low-income earners and retirees to long-term investors.

7. RESP – Registered Education Savings Plan

RESP helps parents save for their child’s future education:

  • The government contributes up to $7,200 through the Canada Education Savings Grant

  • Growth inside the plan is tax-deferred

  • When withdrawn, funds are taxed in the student’s name (typically low tax rate)

RESP is a smart financial strategy if your child plans to attend college or university in Canada.

8. T1 – Personal Tax Return

Every year, Canadian residents must file a T1 tax return with CRA. This includes:

  • All sources of income: employment, investments, self-employment

  • Deductions you claim

  • Tax credits you're eligible for (age, dependents, tuition, transit, etc.)

Deadlines:

  • April 30 for most individuals

  • June 15 if self-employed (but any tax owed is still due by April 30)

9. GST/HST Credit – Quarterly Tax-Free Payment

CRA provides this tax-free quarterly benefit to low-to-moderate income individuals and families:

  • For singles, couples, and those with children

  • No need to apply—just file your tax return on time each year

  • You may also qualify for related provincial credits like the Ontario Trillium Benefit or BC Climate Action Credit

10. Other Terms to Know

  • Notice of Assessment (NOA): CRA’s confirmation that your return was processed. It shows any refund or balance owing.

  • NETFILE: CRA’s online filing system for fast, secure tax return submission.

  • SIN (Social Insurance Number): Required for working and filing taxes in Canada.

  • Contribution Room: The annual limit you can contribute to your TFSA or RRSP.
