Investment accounts explained: TFSA, RRSP and FHSA vs Roth IRA, 401(k) and HSA (2026)

Investment accounts are wrappers. The account decides how your money is taxed; what's inside it (funds, stocks, cash) is a separate choice. Canada's main accounts are the TFSA, RRSP, FHSA and RESP. The US equivalents are the Roth and Traditional IRA, the 401(k), the HSA and the 529. Each has its own 2026 limit and rules, summarized below in plain language.

If you only read one thing: pick the account for the goal and the tax treatment, then pick the investments. The same fund can be taxed very differently depending on which account it sits in.

The three ways an account can be taxed

Almost every account fits one of three patterns:

Two accounts get the best of both, deductible going in and tax-free coming out, as long as you use them for their purpose: the FHSA (a first home in Canada) and the HSA (medical costs in the US).

Canada

TFSA (Tax-Free Savings Account)

• What it is: an account where growth and withdrawals are tax-free.
• How room works: you get the annual limit each year from the year you turn 18, unused room carries forward, and anything you withdraw is added back on January 1 of the next year.
• Watch out for: re-contributing a withdrawal in the same calendar year without enough room. Over-contributions cost 1% a month on the excess. US dividends inside a TFSA also lose 15% to US withholding tax, which you can't get back.

RRSP (Registered Retirement Savings Plan)

• What it is: contributions reduce your taxable income now; you pay tax when you withdraw, ideally in retirement at a lower rate.
• Deadline: contributions in the first 60 days of a year can count for the previous year. For the 2026 tax year, that's March 1, 2027.
• Extras: the Home Buyers' Plan lets you withdraw up to $60,000 for a first home and repay it over 15 years. The Lifelong Learning Plan allows up to $20,000 for school.
• Watch out for: withdrawals outside those programs are taxed, and the room is gone for good. The RRSP must be converted to a RRIF or annuity by the end of the year you turn 71.

FHSA (First Home Savings Account)

• What it is: deductible going in, tax-free coming out for a first home.
• Watch out for: room only starts building once the account is open, so opening early helps even if you can't contribute much yet. Full details in FHSA explained.

RESP (Registered Education Savings Plan)

• What it is: education savings for a child, with the Canada Education Savings Grant adding 20% on the first $2,500 a year, up to $7,200 per child in total.
• Watch out for: grants have to be returned if the money isn't used for school.

Non-registered accounts

• What it is: no limits and no tax shelter. Half of a capital gain is taxable (the 50% inclusion rate; a proposed increase was cancelled in March 2025). Canadian dividends get a tax credit.

United States

Roth IRA

• What it is: after-tax contributions, tax-free growth, tax-free qualified withdrawals.
• Who can contribute: you need earned income. In 2026, the ability to contribute phases out between $153,000 and $168,000 of income for single filers, and $242,000 to $252,000 for married couples filing jointly.
• Withdrawals: your contributions can come out any time, tax- and penalty-free. Earnings are tax-free once the account is five years old and you're 59½ (with some exceptions).
• Watch out for: the $7,500 limit is shared with any Traditional IRA you have.

Traditional IRA

• What it is: contributions may be tax-deductible, and withdrawals are taxed. If you or your spouse have a workplace plan, the deduction phases out at higher incomes.
• Watch out for: a 10% penalty on most withdrawals before 59½, and required minimum distributions later in life.

401(k) and 403(b)

• What it is: a workplace plan, often with an employer match on top of your own $24,500. Many plans offer a Roth 401(k) option.
• New for 2026: if your prior-year wages were over $150,000, catch-up contributions (age 50+) must go in as Roth.
• Watch out for: vesting schedules on the employer's money, and plan fees.

HSA (Health Savings Account)

• What it is: deductible going in, tax-free growth, and tax-free withdrawals for medical costs. You need a high-deductible health plan to contribute.
• Watch out for: non-medical withdrawals before 65 are taxed and hit with a 20% penalty.

Taxable brokerage account

• What it is: no limits, no shelter. Investments held more than a year get long-term capital gains rates (0%, 15% or 20%); a year or less is taxed as ordinary income.

TFSA vs Roth IRA, side by side

They're the two accounts people compare most across the border:

A note for cross-border investors

• Canadians holding US stocks: US dividends are generally exempt from US withholding inside an RRSP, but lose 15% inside a TFSA or FHSA. That's one reason some Canadians hold US dividend payers in their RRSP.
• Americans in Canada: the IRS doesn't recognize the TFSA as tax-free, and many Canadian funds count as PFICs with heavy US reporting. Get cross-border tax advice before opening one.

How to know which account fits you

Start from the goal:

• A first home soon? FHSA (Canada), or a high-interest savings account if it's only a year or two away.
• Retirement? RRSP or TFSA (Canada); 401(k) match, then a Roth IRA (US).
• Flexible, unknown goal? TFSA (Canada); Roth IRA contributions or a taxable account (US).
• A child's education? RESP (Canada); 529 (US).

Then check your available room. In Canada, CRA My Account shows your TFSA, RRSP and FHSA room. Bywell groups your holdings by account type so you can see what sits in each wrapper. For the TFSA and RRSP decision in more depth, see TFSA vs RRSP for beginners.
