The Best Retirement Accounts, and Which One to Fund First

The short answer: it is about the order, not the account#

The mistake almost everyone makes is treating this as a single choice — 401(k) *or* IRA, Roth *or* Traditional. The people who end up with the biggest nest egg do not pick one account; they fund several in the right sequence. Strip away the jargon and the consensus order among fee-only planners is boringly consistent.

Fund your 401(k) up to the full employer match first, because that match is a 50% to 100% instant return you cannot get anywhere else. Then max a health savings account (HSA) if you qualify, because it is the only account taxed favourably three separate ways. Then max a Roth IRA. Then circle back and max out the 401(k). Anything left goes into a regular taxable brokerage account.

That is the whole strategy in one paragraph. The rest of this guide explains what each account actually is, so the order makes sense rather than being a rule you follow on faith.

Here is why the sequence pays. Suppose your employer matches your first 4% dollar-for-dollar on a $70,000 salary. Putting in that roughly $2,800 instantly becomes $5,600 — a guaranteed 100% return before a single fund has moved. Nothing else in investing offers that, which is exactly why the match sits at the top of the list and a plain taxable account sits at the bottom.

• 1. 401(k) up to the match — free money, take all of it.
• 2. HSA (if you have a high-deductible health plan) — the only triple-tax-free account.
• 3. Roth IRA — tax-free growth for decades.
• 4. Max the 401(k) — then a taxable brokerage for the rest.

The 401(k): start here for the employer match#

A 401(k) is the retirement plan your employer runs. Money comes straight out of your paycheque, and for 2026 you can put in up to $24,500 of your own salary — plus an $8,000 catch-up if you are 50 or older, and a larger $11,250 catch-up for ages 60 to 63. Most employers match part of what you contribute, and that match is the single best deal in personal finance: a dollar-for-dollar or fifty-cents-on-the-dollar return before your money has invested a cent.

You choose between a Traditional 401(k), where contributions lower your taxable income today and you pay tax on withdrawals in retirement, and a Roth 401(k), where you pay tax now and take it all out tax-free later. The IRS contribution-limit pages are the authoritative place to check the current-year numbers, since they nudge up with inflation most years.

One rule with no exceptions: never leave the match on the table. Turning down a full employer match to pay down low-interest debt or pad savings is refusing a raise.

The IRA: your own account, with far more choice#

An IRA — an individual retirement account — is one you open yourself at a broker, and it is the reason so many people prefer it to a 401(k): instead of a short menu of employer-picked funds, you can hold almost any low-cost index fund you like. For 2026 the limit is $7,500, plus a $1,100 catch-up at 50 and over.

There are two flavours. A Traditional IRA may be deductible now, but the deduction phases out at higher incomes once you are also covered by a workplace plan. A Roth IRA gives no deduction, yet everything grows and comes out completely tax-free, and you can pull your *contributions* (not the earnings) back out at any time without penalty. Roth IRAs have income limits — around a $153,000 to $168,000 single-filer phase-out for 2026 — and higher earners get in through the legal 'backdoor Roth' manoeuvre.

Roth vs Traditional: the decision that trips everyone up#

This is the fork people agonise over, and the logic is simpler than it looks. You are betting on one thing: whether your tax rate will be higher now or in retirement.

Choose Roth (pay tax now) if you expect to be in a higher bracket later — which describes most people early in their careers. Choose Traditional (deduct now) if you are in a high bracket today and expect a lower one in retirement. If you genuinely cannot tell, split your contributions between the two; that 'tax diversification' hedges your bet and gives you flexible taxable and tax-free buckets to draw from later.

A quick gut check makes it concrete. A 26-year-old paying a 12% marginal rate almost always wins with Roth: you lock in today's low rate and never pay tax on decades of growth. A 52-year-old in the 32% bracket who plans to retire somewhere cheaper usually wins with Traditional, banking the deduction now. Most people sit between those poles, which is why splitting contributions is such a common, sensible hedge.

The HSA: the most tax-advantaged account almost nobody maxes#

If you have a high-deductible health plan, the health savings account is quietly the best deal in the tax code. It is the only account with a *triple* tax advantage: contributions are deductible going in, the money grows tax-free, and withdrawals for medical costs come out tax-free too. For 2026 you can contribute $4,400 on your own or $8,750 for a family, with an extra $1,000 once you turn 55.

The trick most people miss: do not spend it. Pay small medical bills out of pocket, invest the HSA like a retirement account, and let it compound for decades. After age 65 you can withdraw it for anything at all — non-medical spending is simply taxed like a Traditional IRA, with no penalty — which makes a maxed, invested HSA one of the most powerful retirement tools you have.

The maths is startling. Max a family HSA at $8,750 a year, invest it instead of spending it, and at a 7% return it can grow past $400,000 over three decades — a tax-free pool aimed squarely at the medical bills that land hardest late in life. Almost nobody uses it this way, which is precisely why it is such a quiet edge.

What you actually hold inside these accounts#

Here is the point that clears up most of the confusion: the account is only the wrapper. A 401(k), an IRA and an HSA are not investments — they are tax-advantaged containers, and you still have to choose what goes inside. For the overwhelming majority of people, that is a handful of low-cost, broadly diversified index funds. The account decides how your gains are taxed; the fund decides how much they grow.

And the single biggest lever is not which account you pick — it is how early you start. A dollar invested at 25 does dramatically more work than a dollar invested at 40, because of compound interest. Opening the account today with a small contribution beats waiting until you can 'do it properly'.

This is also why 'which broker' or 'which exact fund' matters far less than people fear. A plain total-market index fund inside a Roth IRA, funded automatically every month, quietly beats an elaborate strategy you keep tinkering with. Set the contribution, pick one broad fund, and let time carry the load.

Do not lock away money you will need next year#

Retirement accounts trade access for tax breaks. Pull money out of a 401(k) or Traditional IRA before age 59½ and you generally owe income tax plus a 10% penalty, so this is not where your near-term cash belongs. Two things come first: a liquid emergency fund you can reach without penalty, and a clear sense of your retirement number so you know whether you are contributing enough in the first place.

Get those two right and the retirement accounts do their job in the background for thirty years. Skip them and you risk raiding a long-term account at the worst possible moment.

For Canadians: the RRSP and the TFSA#

North of the border the names change but the logic rhymes. The RRSP (Registered Retirement Savings Plan) works like a Traditional account: contributions are deductible now and taxed on withdrawal, with a 2026 limit of 18% of your prior-year income up to $33,810. The TFSA (Tax-Free Savings Account) works like a Roth with training wheels off: you contribute after-tax money, everything grows and comes out tax-free, and — unlike a Roth IRA — you can withdraw any time and the contribution room comes back the next year. The 2026 TFSA room is $7,000.

The order mirrors the US one: grab any employer pension match first, then favour the TFSA in lower-income years and lean on the RRSP deduction in higher-income ones. Canada's official savings and pension plan overview lays out the current limits.

One practical Canadian wrinkle worth knowing: because TFSA room comes back the year after you withdraw, it doubles as a flexible long-term account you can dip into for a house deposit or a real emergency without losing the space for good — something a US Roth IRA does not allow with its earnings.

The mistakes that quietly cost the most#

None of these are exotic. They are the ordinary slips that shave six figures off a lifetime balance, and every one of them is avoidable.

• Leaving the employer match unclaimed — the most expensive mistake on this list, and the easiest to fix.
• Contributing but never investing — money sitting as cash inside a 401(k) or IRA is not working; you have to actually buy the funds.
• Cashing out when you change jobs — roll the old 401(k) into an IRA or your new plan instead of taking the taxed, penalised payout.
• Picking Roth or Traditional on autopilot — a two-minute bracket check can be worth tens of thousands.
• Ignoring fees — a 1% fund fee can quietly eat a fifth of your final balance over a career.
