PocketProof"Should I do a 401(k) or an IRA?" is one of the most common investing questions, and it's built on a false choice — it's not either/or, it's a specific order. Some steps come before others not because of a rule of thumb, but because each one has a different guaranteed value, and the earlier steps in this list are simply better deals than the later ones, regardless of your specific numbers.
High-interest debt
Above ~7-8% APR
Starter emergency fund
~$1,000 in cash
401(k) match
The full employer match
Full emergency fund
3-6 months of expenses
HSA, if eligible
Triple tax advantage
IRA
Roth or Traditional, maxed
401(k) to the max
Beyond just the match
Taxable brokerage
No limit, no tax break
Find where your next dollar actually goes
Check off what you've already got covered — the tool below finds the first tier you haven't finished yet.
Where does your next dollar go?
Each tier, explained
1. High-interest debt
Paying off a credit card at 22% APR is a guaranteed 22% return, before you even consider what the market might do. No tier below this one reliably beats that. "High-interest" usually means anything above roughly 7-8% — most credit cards, many personal loans.
2. Starter emergency fund (~$1,000)
Just enough cash that a flat tire or a broken phone doesn't force you back into debt or out of your investments. See our starter emergency fund guide for how to build this fast.
3. Employer 401(k) match, in full
If your employer matches 50% up to 6% of pay, contributing that 6% gets you an instant 50% return on that money — before it's even invested in anything. Leaving any part of a match unclaimed is turning down guaranteed money.
4. Full emergency fund (3-6 months)
Once the match is captured, finish the safety net before locking more money into retirement accounts — see our emergency fund guide for sizing this to your situation.
5. HSA, if you have one
Only available if you're enrolled in a high-deductible health plan, but it's arguably the single best tax deal available: deductible going in, grows tax-free, and comes out tax-free for qualified medical expenses — a triple advantage no other account on this list offers. 2026 limit: $4,400 self-only / $8,750 family, plus a $1,000 catch-up at 55+.
6. IRA (Roth or Traditional)
More investment choice than most 401(k) plans typically offer, plus real tax advantages either way — Roth if you expect to be in a higher tax bracket later, Traditional if you expect to be lower. (Income limits can affect Roth eligibility — a backdoor Roth conversion or a Traditional IRA are the usual workarounds if you're phased out.) 2026 limit: $7,500, plus a $1,100 catch-up at 50+.
7. 401(k), up to the max
Once everything above is handled, go back and push 401(k) contributions past the match, up toward the full annual limit. 2026 limit: $24,500, plus an $8,000 catch-up at 50+ ($11,250 for ages 60-63 specifically).
This assumes you can actually leave it locked up
Tier 7 only makes sense if that money can realistically stay put until 59½ — 401(k) withdrawals before then generally come with a real penalty on top of the tax owed. If there's a real chance you'll need the cash sooner — a home purchase, a career change, anything in roughly the next decade — the lack of access starts to matter more than the extra tax advantage. In that case, skip ahead to tier 8 for that portion instead: a taxable brokerage account gives up the tax break but keeps the money reachable whenever you actually need it, penalty-free.
8. Taxable brokerage account
No contribution limit and no special tax treatment, but also no early-withdrawal penalty and no required distributions later — full flexibility once the tax-advantaged room above is used up.
Robinhood and Acorns are platforms, not tiers
"I invest through Robinhood" doesn't actually tell you which tier that money is in — Robinhood, Acorns, and similar apps are places to open an account, not account types themselves. The same app can host either this tier (a plain taxable account, no tax advantage) or an IRA (tier 6) — both Robinhood and Acorns offer IRA options alongside their standard investing accounts. What determines the tier is which specific account the money sits in, not which app it's sitting in.
| Account | 2026 limit | Catch-up |
|---|---|---|
| HSA (self-only) | $4,400 | +$1,000 (55+) |
| HSA (family) | $8,750 | +$1,000 (55+) |
| IRA | $7,500 | +$1,100 (50+) |
| 401(k) employee deferral | $24,500 | +$8,000 (50+), or +$11,250 (60-63) |
You probably won't max every tier, and that's fine
Verified: for someone under 50 with self-only HSA coverage, fully maxing the HSA + IRA + 401(k) tiers takes $36,400 of your own contributions in a single year ($40,750 with family HSA coverage, $46,500 with every catch-up contribution available at 50+/55+). That's a lot of money — most people, at most incomes, will never max every single tier, and the order matters far more than reaching the end of it. Getting through tier 3 (the employer match) reliably is a bigger win than most people give it credit for.
What's left after this list
Once every tier above is genuinely maxed, the remaining options get more personal and situational rather than following one universal order: paying extra toward a low-interest mortgage early, real estate, starting a business, or simply directing more toward the taxable brokerage account in tier 8. There's no single right answer here — it depends on your other goals, not a formula.
This order assumes you're already clear of the two things that come before investing at all — see our investing for complete beginners guide for the full on-ramp, including how to actually pick investments once the money reaches whichever tier you're funding. And if the whole point of following an order like this is reaching a real long-term number, our millionaire calculator shows what consistent tier-3-and-beyond contributions can actually turn into over time.
