The $70,000 Question: Which Retirement Account to Fill First (and the Order Almost Everyone Gets Wrong)

There's a correct sequence for funding your accounts that can add six figures to your retirement — yet most people fund them in the exact opposite order.

Most People Fund Their Accounts in the Worst Possible Order

Here's what typically happens: someone opens a brokerage account because it's easy, throws money at it, and only later gets around to their 401(k) — often without even capturing the full company match. That's backwards. Every dollar has a hierarchy of homes, ranked by how much of it the government lets you keep. Putting money in a taxable account while leaving free match dollars on the table is like turning down a raise to pay extra taxes. The accounts aren't interchangeable buckets — they're a ladder, and you climb it in a specific order.

The Order of Operations That Actually Works

The sequence is not complicated, but almost nobody follows it cleanly. First: contribute to your 401(k) up to the full employer match — this is an instant 50% to 100% return you cannot get anywhere else. Second: max your HSA if you're on a high-deductible plan, because it's the only account with triple tax advantages. Third: max an IRA, where your investment choices are cheaper and broader than most workplace plans. Fourth: go back and fill the rest of your 401(k) up to the annual limit. Fifth: anything left over goes into a taxable brokerage. Follow this and every dollar lands in the most tax-efficient home available before spilling into the next.

The Math: What the Right Order Is Worth

Say you can save $15,000 a year and your employer matches 50% on the first 6% of a $80,000 salary — that's $2,400 in free money. Skip the match for 10 years and you've walked away from $24,000 in contributions plus growth: at 7%, that's roughly $35,000 gone. Now the tax drag: $15,000/year in a taxable account, taxed on dividends and gains, might net you an effective 5.5% after taxes instead of 7%. Over 30 years, $15,000/year at 7% grows to about $1.42 million; at 5.5% it's about $1.09 million. That's a $330,000 difference from tax location alone — before counting the match. The order isn't a rounding error. It's a house.

The Mistake: Choosing Roth vs. Traditional on Vibes

The single most common error after the match question is picking Roth versus traditional emotionally instead of mathematically. People hear 'tax-free growth' and dump everything into Roth, even when they're in their peak earning years at a 24% or 32% marginal rate. The rule of thumb: use traditional (pre-tax) when your current bracket is high and you expect it to drop in retirement; use Roth when your bracket is low now and likely higher later. A 22-year-old in the 12% bracket should almost always choose Roth. A 45-year-old dual-income household in the 32% bracket usually shouldn't max Roth first — the pre-tax deduction is worth more today than the tax-free withdrawal decades out.

Why the HSA Punches Above Its Weight

If you have a high-deductible health plan, the HSA quietly beats every other account on a pure tax basis. Contributions go in pre-tax, growth is tax-free, and withdrawals for medical expenses are tax-free — no other account does all three. After age 65, you can withdraw for any reason and just pay ordinary income tax, making it function like a traditional IRA with a medical bonus. The trick: don't spend it. Pay current medical bills out of pocket, let the HSA compound for decades, and keep your receipts. A $4,400 annual contribution invested for 25 years at 7% becomes roughly $278,000 — completely untaxed if used for healthcare, which you will absolutely have in retirement.

What to Do This Week

Pull up your 401(k) portal and confirm you're contributing at least enough to capture the full match — if you're not, fix your contribution percentage today. Next, check whether your health plan qualifies you for an HSA; if it does and you're not maxing it, that's your next dollar. Then open or fund an IRA and decide Roth versus traditional based on your marginal bracket, not on what a random influencer said. Finally, automate all of it so the money moves before you can spend it. This whole sequence takes about an hour to set up and compounds for the rest of your working life.

The WC Take

Stop scattering money randomly across accounts. Follow the order of operations: capture your full 401(k) match, max your HSA if you're eligible, then decide between Roth and traditional based on your bracket. Run your actual numbers through our Retirement Calculator at /tools/calculators/retirement before you set a single contribution percentage — guessing costs more than most people realize.

Key Takeaways

  • Fund accounts in this order: 401(k) match, HSA, IRA, rest of 401(k), then taxable brokerage.
  • Most people put money in a taxable account first — that's the least tax-efficient home for your dollars, not the easiest win it feels like.
  • Tax location alone can swing a 30-year outcome by $330,000 on $15,000/year in savings.
  • This week: confirm you're capturing your full employer match, then pick Roth vs. traditional based on your actual marginal tax bracket — not on vibes.

Frequently Asked Questions

What order should I fund my retirement accounts in?

Start with your 401(k) up to the full employer match, then max your HSA if you have a high-deductible health plan, then max an IRA (Roth or traditional based on your bracket), then return to max the rest of your 401(k). Any money left after that goes into a taxable brokerage account. This sequence prioritizes free money and the biggest tax advantages first.

What are the 2026 contribution limits for a 401(k) and IRA?

For 2026, the 401(k) employee contribution limit is $24,500 with a $8,000 catch-up if you're 50 or older. The IRA limit is $7,500 with a $1,100 catch-up. HSA limits are $4,400 for individuals and $8,750 for families. Always confirm the current year's figures, as the IRS adjusts them for inflation.

Should I max my 401(k) before contributing to an IRA?

Only up to the employer match. After you capture the full match, an IRA usually offers better, cheaper investment options than most 401(k) plans, so it's smart to max the IRA next before returning to fill the rest of your 401(k). The exception is if your 401(k) has excellent low-cost funds and you value the higher contribution ceiling.
