TFSA, RRSP or FHSA? Where Your 20% Should Go First

The 50/30/20 rule tells you how much to save: about a fifth of your take-home pay. It says nothing about where to put it. In Canada that's a real question, because you have three tax-advantaged accounts that each work differently. Here's a plain-language order of operations for your 20%, with the 2026 limits and the mistakes I see most often.

The Three Accounts in One Minute

Your personal TFSA and RRSP room can be higher than these figures because unused room carries forward. Your exact numbers are in CRA My Account. Check there rather than guessing, because over-contributing triggers a penalty.

An Order of Operations for Your 20%

There's no single right answer for everyone, but this sequence works for most households. Move to the next step only once the one before it is handled.

Step 1: A starter emergency fund

Before investing anywhere, build a cushion of at least one month of essential expenses. Then grow it toward three to six months. Keep it somewhere boring and accessible: a high-interest savings account, or a TFSA held in cash or a savings product rather than invested in the market. An emergency fund that has dropped 20% when you need it isn't doing its job.

Step 2: Capture any employer match

If your employer matches contributions to a group RRSP or pension, contribute enough to get the full match. It's an immediate return you won't find anywhere else, and it counts toward your 20%.

Step 3: Pay off high-interest debt

Paying off a credit card charging 20% or more is a guaranteed 20% return. No investment reliably beats that. Put the bulk of your 20% toward high-interest debt until it's gone, while keeping your emergency fund in place so you don't slide back into it.

Step 4: The FHSA, if you're a first-time buyer

If you might buy your first home in the next 15 years, the FHSA is the best deal in Canadian tax law: you get a deduction when you put money in and pay no tax when you take it out for a qualifying home. Open one as soon as you think you might use it, because your room only starts building once the account is open. If you never buy, the balance can generally be transferred to your RRSP without using any RRSP room, so there's little downside to starting.

Step 5: RRSP or TFSA, based on your tax bracket

For everything else, the choice between RRSP and TFSA mostly comes down to one question, covered next.

The RRSP is a bet that your tax rate is higher now than it will be when you withdraw. The TFSA is the bet that it isn't.

RRSP or TFSA? The One Question That Decides It

Ask yourself: is my tax rate higher today than it's likely to be in retirement?

• If yes, which is typical for people in their peak earning years, the RRSP usually wins. You get a deduction at a high rate now and pay tax at a lower rate later.
• If no, which is common early in your career, on a modest income, or if you expect a good workplace pension, the TFSA usually wins. A deduction at a low rate isn't worth much, and TFSA withdrawals don't count as income in retirement.
• If you're not sure, splitting your savings between both is a reasonable choice, not a cop-out.

One more consideration for lower-income retirees: RRSP and RRIF withdrawals count as income, which can reduce income-tested benefits like the Guaranteed Income Supplement. TFSA withdrawals don't. For someone who expects a low income in retirement, that can make the TFSA clearly better.

Three Examples

These are illustrations of the reasoning, not recommendations for your situation.

A 27-year-old renter in Abbotsford earning $55,000

Take-home pay is about $3,600 a month, so the 20% is about $720. With no emergency fund yet, the first few months go to building one. After that, the FHSA comes first because a home purchase is a realistic goal, and the deduction is a bonus on top of tax-free withdrawal. Any remaining savings go to a TFSA, since a deduction at this income is worth relatively little.

A couple in their mid-40s, homeowners, earning $160,000 combined

The emergency fund is in place and there's no credit card debt. Both capture their employer's group RRSP match. Beyond that, RRSPs make sense because their current tax rate is likely higher than it will be in retirement. They put their refunds into TFSAs, which gives them flexible savings for things like a new roof or a vehicle.

The first priority is a separate account holding back money for the CRA, because nobody withholds tax from gig income. The second is a buffer to smooth lean months, held in a TFSA in cash. Only then do longer-term savings start. A TFSA is often the better fit here because the money stays accessible if income drops. For the full method, see budgeting on an irregular income.

Mistakes That Cost Canadians Money

• Re-contributing a TFSA withdrawal in the same year. Withdrawn amounts come back as room on January 1 of the following year, not right away. Putting the money back early can create an over-contribution, which is penalized at 1% per month.
• Treating a TFSA like a savings account only. The name is misleading. A TFSA can hold investments, and for long-term money, leaving it all in low-interest cash wastes the tax-free growth.
• Waiting to open an FHSA. Room doesn't accumulate until the account exists, and you can only carry forward one year of unused room.
• Spending the RRSP refund. See above. It erases much of the benefit.
• Guessing your room. Check CRA My Account before contributing, especially if you have a workplace pension, which reduces your RRSP room.

My take

In my years across the desk, the most common mistake I saw wasn't choosing the "wrong" account. It was not choosing at all: money sitting in a chequing account for years because the decision felt complicated. Any of these three accounts beats that. If you're stuck, follow the order above, open the account that fits your next step, and set up an automatic contribution on payday. You can fine-tune the mix later. You can't get back the years you didn't save.

And when the decision does get genuinely complicated, such as large balances, a workplace pension, self-employment, or planning withdrawals in retirement, that's when an hour with a Certified Financial Planner is money well spent.
