TFSA vs RRSP vs FHSA: Which Account Should You Open First?

A clear decision guide for first-time Canadian investors — including where your first $500/month should actually go in 2026.

Three registered accounts. Three different rules. And everyone on Reddit has a different opinion. Here's the actual answer — it depends on two things: your income and whether you might buy a home.

This guide gives you a decision framework, not a one-size-fits-all answer. By the end, you'll know exactly which account to open first and why.

Quick Decision Matrix — 3 Scenarios

Find your situation below. These aren't oversimplifications — they're the rules most financial planners actually use.

Scenario A

You might buy a home in the next 15 years

Whether you earn $45K or $200K, the FHSA is the best-of-both-worlds account for prospective first-time buyers. You get a tax deduction on contributions (like an RRSP) and tax-free withdrawals for a home purchase (like a TFSA).

→ FHSA first, then TFSA
Scenario B

You earn under ~$55K and won't buy a home

At lower income levels, the RRSP tax deduction isn't worth much — your marginal rate is too low. A TFSA gives you flexibility: withdrawals are tax-free and room is restored the next year.

→ TFSA first, RRSP later
Scenario C

You earn over $80K and won't buy a home

At higher incomes, RRSP contributions slash your tax bill meaningfully. A $10,000 RRSP contribution saves ~$3,300 in taxes at a 33% marginal rate. Hold RRSP deductions for your highest-earning years.

→ RRSP first, then TFSA

The FHSA override: If there's any chance you'll buy a home in the next 15 years, open an FHSA first — regardless of income. The tax math nearly always favours it over TFSA or RRSP alone for prospective buyers.

The FHSA: The "Third Door" Most Canadians Miss

The FHSA opened in April 2023 and is still underutilized. Many Canadians don't realize you can contribute to an FHSA even if you're not sure you'll buy — unused funds simply roll to your RRSP. There's essentially no downside to opening one early.

Unused annual room carries forward by one year (so if you contribute $4,000 in year one, you can contribute $12,000 in year two). Open the account as soon as you're eligible — the clock on room carryforward doesn't start until you open it.

Key restriction: To open an FHSA, you must be a Canadian resident, at least 18, and must not have lived in a qualifying home you owned at any point in the current year or the preceding four calendar years. Once you meet the conditions, open it immediately — room begins accumulating the year you open it.

TFSA: Tax-Free Forever (Contributions Aren't Deductible)

RRSP: Defer Taxes to Retirement (Most Powerful at High Incomes)

HBP vs FHSA for first-time buyers: The FHSA is almost always better than the HBP for first-time buyers. FHSA withdrawals don't need to be repaid. HBP withdrawals must be repaid over 15 years (or added back to income). Consider the FHSA your primary vehicle and the HBP as a backup top-up if needed.

The Income-Based Tipping Points

The right account depends heavily on your marginal tax rate. Here's the framework most financial planners use:

Income Range Marginal Rate (approx.) Strategy Why
Under $55,000 20–29% TFSA first Marginal rate too low to make RRSP deduction meaningfully valuable. TFSA gives flexibility without locking funds into retirement.
$55,000 – $80,000 29–33% FHSA if buyer, else split RRSP deductions start becoming worthwhile. If you might buy a home, FHSA wins. Otherwise, split contributions between RRSP and TFSA.
$80,000 – $100,000 33–43% RRSP first (+ FHSA if buyer) Meaningful tax refunds on RRSP contributions. FHSA adds deduction power for home buyers. TFSA with remaining room.
Over $100,000 43–53% RRSP + FHSA max first Every RRSP dollar shelters 43–53 cents from tax. Maximize RRSP and FHSA before TFSA. Consider delaying RRSP deductions to even higher income years.

These are Canadian federal + average provincial combined marginal rates. Your exact province matters — Alberta, Ontario, and BC all have different brackets. Use the CRA's online tax calculator or a tax professional for precise numbers.

Note for New Canadians

Two important differences apply if you recently became a Canadian resident:

Practical tip: If you're a new Canadian with several years of employment income but limited TFSA room, consider directing extra savings to your RRSP while your TFSA room catches up. Once your TFSA room builds, you can rebalance your strategy.

The "$500/Month Contribution Waterfall" — Worked Examples

Where should each dollar go? Here are three real-world scenarios showing how to prioritize $500–$667/month.

🏠 Scenario: First-time buyer earning $70,000/year

1

$667/month → FHSA (maxes annual $8,000 limit). Get the deduction now, grow tax-free, withdraw tax-free for the home. This is the top priority — open the account today and start the clock on room.

2

Remaining savings → TFSA. After maxing the FHSA, put extra into a TFSA for flexibility. At $70K income, the RRSP deduction is useful but not as urgent — prioritize TFSA for optionality while income is moderate.

🏢 Scenario: Renter earning $45,000/year

1

$500/month → TFSA. At $45K income, the RRSP deduction saves you roughly 20–29 cents per dollar — not terrible, but not transformative. TFSA first gives maximum flexibility with no lock-in. Revisit RRSP when income rises above $55K.

2

Once income exceeds ~$55K → add RRSP contributions. Your accumulated RRSP room carries forward — no need to rush while marginal rates are low. Bank the deductions for higher-earning years.

💼 Scenario: High earner at $120,000/year

1

$500+/month → RRSP. At $120K, your marginal rate is roughly 43–53% depending on province. Every $1,000 RRSP contribution could save $430–$530 in taxes. Maximize before the year end.

2

$667/month → FHSA (if home buyer). Stack both deductions — RRSP + FHSA is extremely powerful at $120K. A full FHSA year ($8,000) combined with RRSP contributions can produce a significant tax refund.

3

Remaining → TFSA. After maxing RRSP and FHSA, TFSA handles the overflow and acts as a flexible short-to-medium term reserve.

Which Account to Open First — The One-Sentence Summary

The good news: these aren't irreversible decisions. You can rebalance as your income changes, your life plans evolve, or the rules change. The important thing is to start.

Once you know which account to open, the next question is which platform to use — especially if you want FHSA access and low fees.
