How to Use a TFSA (Tax-Free Savings Account)

This article is for educational purposes only and is not financial or tax advice. For guidance specific to your situation, speak with a registered financial advisor or tax professional.

You just turned 18, you have been picking up shifts at work, and you have heard something about a TFSA. Maybe a parent mentioned it. Maybe you saw it on social media. Either way, nobody explained it in a way that actually made sense for your situation.

Most guides about TFSAs are written for adults with full-time jobs and thousands of dollars to invest. This one is written for you: a student or young Canadian who is just getting started and wants to know what a TFSA actually does, how to open one, and what to put in it when you do not have a lot to work with.

The short version is this: a TFSA is the best place to put your savings when you are young and your income is low. It lets your money grow without being taxed, and you can take it out whenever you want without any penalty. The sooner you open one, the more you benefit. This guide covers exactly how to use it at your stage of life.

What Is a TFSA and Why Does It Matter to You Right Now?

A Tax-Free Savings Account (TFSA) is a government-registered account that lets you save and invest money without paying tax on what it earns. Any interest, dividends, or investment gains inside the account belong entirely to you. When you take money out, you owe nothing in tax and no one asks what you are spending it on.

Here is why this matters when you are 17 to 20 years old. Right now, your income is probably low, which means the tax benefits of other accounts like the RRSP do not really apply to you yet. The TFSA is different. It does not require any earned income, it has no deadline, and it gives you full flexibility to use your money for anything at all. A car, school supplies, an emergency, or your first apartment deposit. It grows with you.

Think of it this way: every year you are 18 or older and a Canadian resident, you earn $7,000 in TFSA contribution room. That room stacks up whether you use it or not. The longer you wait to open one, the more of that head start you give up.

You can verify your eligibility and find more details at the Canada Revenue Agency TFSA page.

Who Can Open a TFSA? What If You Are Under 18?

To open a TFSA in Canada, you need three things: you must be a Canadian resident, you must have a Social Insurance Number (SIN), and you must be at least 18 years old. In most provinces (Ontario, Alberta, Quebec, Manitoba, Saskatchewan, and PEI), the age of majority is 18. In British Columbia, Nova Scotia, New Brunswick, Newfoundland and Labrador, and the territories, it is 19 — but your contribution room still accumulates from age 18 regardless.

If you are still 16 or 17, you cannot open a TFSA yet, but the room you are accumulating right now (starting the year you turn 18) will be waiting for you. In the meantime, a regular savings account at a bank is a good place to hold money until you are eligible.

If you are a parent reading this with a teen about to turn 18, one of the most useful financial gifts you can give them is helping them open a TFSA and make their first contribution. A small amount in a TFSA at 18 has decades to grow tax-free.

How Much Can You Put In? (And How Much Should You, Realistically?)

The 2026 TFSA annual contribution limit is $7,000. That is the maximum you can add this year. Your total available room depends on how long you have been eligible:

• Eligible since 2026 (just turned 18): $7,000
• Since 2025: $14,000
• Since 2024: $21,000
• Since 2023: $26,000
• Since 2022: $33,000
• Since 2020: $47,000
• Since 2009 (eligible from the start): $109,000

Now, the more useful question for most students is not “how much room do I have?” but “how much can I actually afford to put in?”

If you work a part-time job and bring home $600 to $1,000 a month, you are not going to max out your TFSA right away, and that is completely fine. Even $50 or $100 a month grows significantly over time in a tax-free account. The goal at this stage is to start the habit and let time do the work.

For example: $100 a month in a TFSA from age 18, growing at a 7% average annual return, grows to over $52,000 by age 35. The same amount in a taxable account grows to less because you pay tax on the gains every year. The difference compounds quietly over time, which is exactly why starting young matters.

How to Open Your First TFSA

Opening a TFSA takes about 15 minutes online. You need your Social Insurance Number (SIN) and a piece of government-issued ID. Most major banks (TD, RBC, Scotiabank, BMO, CIBC) let you open a TFSA account through their apps or websites.

Wealthsimple lets you open a TFSA with no account fees and no minimum balance. You can start with $5 and invest in simple portfolios built for beginners. A lot of students start here because the interface is clean and you do not need to know anything about investing to get going.

Questrade gives you more control if you want to pick your own ETFs or stocks. ETF purchases are free, which makes it cost-effective if you plan to invest regularly in index funds.

If you are not sure about investing yet and just want somewhere safe to put savings, a high-interest savings TFSA at a bank or credit union earns tax-free interest while your money stays accessible. It earns less over time than an invested TFSA, but it is a solid starting point while you learn.

What Should You Actually Put Inside Your TFSA?

This is where most teen guides stop being useful, because they say “consider ETFs or GICs” without explaining what that means for someone with $200 and no investing experience.

Here is the honest breakdown by where you are:

If you have under $500 and are just starting out: Put it in a high-interest savings account inside your TFSA. You are earning tax-free interest while you learn. Do not worry about investing yet. Focus on building the habit of putting money in.

If you have $500 to $2,000 and a timeline of 2+ years: Consider a simple balanced ETF — a single fund that holds a mix of Canadian stocks, global stocks, and bonds. On Wealthsimple, this is as simple as selecting a “balanced” or “growth” portfolio. On Questrade, you would buy a single-ticket ETF. These grow with the market over time, carry low annual fees (under 0.25%), and require no ongoing decisions on your part).

If you are saving for something specific in the next 6 to 12 months (a car, a trip, moving costs): Keep that money in a savings deposit or a short-term GIC inside your TFSA. You do not want money you need soon tied up in the stock market where it could drop right before you need it.

The most important thing is not picking the perfect investment — it is getting started. A simple approach beats a perfect-but-never-started approach every time. If you need help figuring out how much of your income you can actually save each month, our guide on how much money a teenager should save walks through realistic numbers.

How Withdrawals Work: The Freedom Part

One of the best things about the TFSA for students is that you can take the money out whenever you need it — no penalty, no tax, no explanation required.

This matters for real student situations. Say you put $800 in your TFSA over the summer, then you need $400 in September for textbooks. You can pull it out and use it. In the spring, once you have saved it back up, you can re-deposit it — but here is the important rule: the room only restores on January 1 of the following year.

So if you withdrew $400 in September and tried to put $400 back in November, and you had already used all your room for the year, you would be over-contributing and owe a penalty. Wait until January, and the room comes back.

This catches a lot of first-time TFSA users. Write it down: withdrawal room restores January 1, not immediately.

The Mistakes Teens Make With Their First TFSA

Not opening one. Room accumulates whether you use it or not, but tax-free growth does not. Every year you leave the account empty is a year of compounding you cannot get back.

Only using it as a savings account. A TFSA holding $3,000 in a 2% savings deposit while you have a 5-year timeline is still better than nothing, but it is not using the account to its potential. Once you are comfortable, move some of it into growth investments.

Re-contributing a withdrawal in the same year. The most common penalty trap. If you take money out in July and put it back in October, you may be over-contributing if your room was already used. Room restores in January, not when you re-deposit.

Treating it like a chequing account. Moving money in and out repeatedly throughout the year makes it easy to lose track of your contribution room. Make deposits intentionally, track them, and check your room at CRA My Account before making large deposits.

Once you are comfortable with the TFSA, the natural next question is how it compares to an RRSP or the newer First Home Savings Account. Our guide on TFSA vs RRSP for Canadian students covers that comparison in full, and explains why for most students the TFSA comes first. And if budgeting is still a work in progress, start with our teen budgeting guide to figure out how much you can realistically set aside each month.

Frequently Asked Questions

I am 16. Can I open a TFSA now?

No. You need to be at least 18 (or 19 in some provinces) to open a TFSA. But your contribution room starts accumulating in the year you turn 18 automatically. When you hit the right age, that room will be there waiting for you. Until then, a regular savings account is a good holding spot.

Can I open a TFSA if I have never filed taxes?

Yes. Unlike an RRSP, the TFSA does not require any earned income or a filed tax return to open or contribute. As long as you are 18+, a Canadian resident, and have a SIN, you are eligible. Filing your taxes is still a good idea (you may be entitled to credits and refunds), but it is not a requirement for the TFSA.

What if I only have $50 to start?

Open it anyway. Wealthsimple has no minimum balance, so $50 is enough to get started. The most important step is opening the account and getting the habit going. You can always add more later.

Does my TFSA affect OSAP (Ontario Student Assistance Program) or student loans?

TFSA withdrawals do not count as income, so they should not directly affect your OSAP eligibility in the way that employment income does. However, asset-testing rules for student aid can vary by province and change year to year. Check with your province’s student aid office for details specific to your situation before making financial decisions based on this.
