If you have spare cash and a TFSA, an RRSP, and now an FHSA all sitting open, the hard part is no longer whether to save but which account to fill first. Get the order right and the same dollars can buy a deduction today, grow tax-free, and come out tax-free for a first home. Get it wrong and you either leave free money on the table or lock savings into the account with the worst rules for your situation.
This is the 2026 decision order, the single exception that beats it, and the short reasoning behind each step. If you want the rules of any one account in depth, the FHSA contribution rules post covers that account on its own; this post is about choosing between the three.
The one-line answer
For a Canadian who is saving for a first home and earns a normal salary, the fill order in 2026 is:
- Employer RRSP match: up to the full match.
- FHSA: up to $8,000 this year.
- TFSA: up to your available room.
- Remaining RRSP room: whatever is left after the match.
If you are not buying a home, the FHSA drops out and the order becomes: match, then a straight TFSA-or-RRSP choice based on your tax rate now versus in retirement.
The rest of this article is why that order holds, and when to break it.
What each account is actually best at
The three accounts look similar (all shelter investment growth from tax), but each is built for a different job.
- TFSA: flexibility. Contributions are not deductible, but growth and withdrawals are completely tax-free, and withdrawing this year restores that room next year. It is the only one of the three you can dip into for an emergency without tax or a permanent loss of room. Room accrues from age 18 whether or not you ever opened one. Not sure what yours is? The free TFSA contribution room calculator adds up every year's limit for you.
- RRSP: tax deferral. Contributions are deductible now and taxed on the way out in retirement, when your rate is usually lower. Its superpower is the employer match: many workplace plans add 50 cents or a dollar for every dollar you put in, up to a cap. That match is the highest-return move in personal finance. Not sure how much new room you have this year? The free RRSP contribution room calculator estimates it from your earned income and pension adjustment.
- FHSA: the best of both, for one purpose. Deductible going in like the RRSP, tax-free coming out like the TFSA, with no repayment, but only if the money funds a qualifying first home. It gives $8,000 of room a year from the year you open it, capped at $40,000 for life. The FHSA contribution room calculator works out your 2026 room from your open year.
Step 1: take the employer match, always
If your employer matches RRSP or group-plan contributions, that comes before everything: before the FHSA, before the TFSA, before paying down anything but the highest-rate debt.
A 50% match is an instant, guaranteed 50% return on the matched portion. No investment inside any registered account reliably returns that. Skipping it to "optimize" between the TFSA and FHSA is optimizing the small decision while losing the big one. Contribute exactly enough to capture the full match, then move on to step two.
The only thing that legitimately jumps ahead of the match is high-interest debt: a credit-card balance at 20% costs you more than a 50% match on a small contribution earns. Clear that first.
Step 2: fill the FHSA (if a first home is on the table)
For a first-time buyer, the FHSA is the strongest registered account Canada has. It is the only one that gives you a deduction on the way in and a tax-free withdrawal on the way out. The RRSP gives you the deduction but taxes the withdrawal in retirement; the TFSA gives you the tax-free withdrawal but no deduction. The FHSA gives you both.
It also stacks with the RRSP Home Buyers' Plan: you can pull up to $40,000 from the FHSA plus up to $60,000 from your RRSP under the HBP for the same purchase. The difference is repayment: FHSA money is never repaid, while HBP money has to go back into your RRSP over 15 years or be added to your taxable income. So the FHSA is the cleaner instrument, and the HBP is what you reach for only after the FHSA is full.
One catch worth repeating: FHSA room only starts the year you open the account, and it does not accrue retroactively. If buying a home is even a maybe within the next decade, opening an FHSA now (even with a $0 deposit) starts the clock at no cost. The mechanics, deadlines, and the four numbers worth tracking are in the FHSA contribution rules guide.
Step 3: fill the TFSA
Once the match is captured and the FHSA is funded for the year, the TFSA comes next for most people.
Its edge is flexibility. Life between now and retirement is uncertain (a job change, a move, a medical bill), and the TFSA is the only account you can draw on without tax and without permanently destroying the room. That optionality is worth more than the modest tax-timing advantage an RRSP might offer at a middle income. The TFSA is also the better long-term home if you expect your retirement tax rate to be similar to or higher than today's, which is increasingly common for high savers.
If you have lost track of your TFSA room across a decade of contributions and withdrawals, the TFSA contribution room calculator reconstructs it from your birth year and residency.
Step 4: top up the RRSP
Whatever is left goes to remaining RRSP room beyond the match. The RRSP earns its keep when your current marginal tax rate is meaningfully higher than the rate you expect in retirement, because you deduct at the high rate now and withdraw at the low rate later. That is the textbook case for a high earner in their peak earning years.
A useful trick: you do not have to claim an RRSP deduction the year you contribute. If you are in a lower-income year, contribute now to start the tax-free compounding but carry the deduction forward to a higher-income year. The same carry-forward flexibility applies to the FHSA deduction.
When to break the order
The four-step order is a default, not a law. Break it when:
- You earn a high income and won't buy a home. Skip the FHSA (you cannot withdraw tax-free without a qualifying purchase) and weight the RRSP more heavily. The deduction at a high marginal rate is the main event.
- You earn a modest income. The RRSP deduction is worth little at a low tax rate, and you may claw back income-tested benefits in retirement. Favour the TFSA, and the FHSA if a home is a goal.
- You're self-employed or income is lumpy. Lean on the TFSA and the carry-forward on RRSP and FHSA deductions, claiming them in your best years.
- You live in Quebec. Provincial tax rates change the RRSP-versus-TFSA math at the margins; if you want the local picture, see our note on tracking finances in Quebec.
Seeing all three in one place
What makes the fill order hard to execute is that the three accounts usually live at three different institutions. Your TFSA might be at one brokerage, your RRSP in a group plan at work, and your FHSA at a bank. No single statement shows you all three, your combined room, or how close you are to the FHSA's $40,000 cap.
That is the gap Mozaic is built for. It connects to the major Canadian brokerages through SnapTrade and to the major banks through Plaid, all read-only, and adds your TFSA, RRSP, and FHSA into one net-worth picture in CAD, with each account's tax treatment flagged correctly. The connection cannot move money, place trades, or change positions. Data lives in Google Cloud's Montréal region under PIPEDA and Quebec Law 25; the full posture is at /security, and pricing is a flat $99 CAD/year at /pricing.
The bottom line
Capture the employer match, fund the FHSA if a first home is realistic, fill the TFSA, then top up the RRSP. Bend that order toward the RRSP at high incomes and toward the TFSA at modest ones. The only real mistake is leaving the match or the FHSA's deduction-in-tax-free-out combination unused.
Start by knowing your numbers: the free TFSA, RRSP, and FHSA calculators take under a minute each, no login required. Then, if you hold accounts at more than one institution, Mozaic tracks all three together with each account's tax treatment flagged: the TFSA tracker, the RRSP tracker, and the FHSA tracker. The pricing page walks through the trial.
