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When withdrawn, funds are taxed in the student’s name (typically low tax rate)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