401(k) vs IRA: Which Should You Prioritize in 2026?
Published June 12, 2026 · 6 min read
Most Americans have access to a 401(k) through work and can also open an IRA on their own. But which should come first? The answer isn't always obvious — it depends on your employer match, your tax bracket, and your retirement goals. This guide breaks it down.
2026 Contribution Limits at a Glance
| Account | Under 50 | 50+ Catch-Up |
|---|---|---|
| 401(k) | $23,500 | $31,000 |
| Traditional IRA | $7,000 | $8,000 |
| Roth IRA | $7,000 | $8,000 |
| HSA (Family) | $8,550 | $9,550 |
The Golden Rule: Never Leave Free Money on the Table
Step 1: Contribute enough to get your full 401(k) match.
An employer match is an instant 50-100% return. No investment in the world beats that. If your employer matches 50% up to 6% of your salary, contribute at least 6%.
The Optimal Investment Order (The "Waterfall")
After decades of research, the personal finance community largely agrees on this order:
- 401(k) up to the match — Instant 50-100% return
- HSA (if eligible) — Triple tax advantage: tax-deductible contributions, tax-free growth, tax-free withdrawals for medical expenses
- Roth IRA — Tax-free growth and withdrawals in retirement. Also more flexible (can withdraw contributions anytime penalty-free)
- Back to 401(k) up to the limit — Max out the remaining tax-advantaged space
- Taxable brokerage account — For anything beyond the annual limits
Roth vs Traditional: The Tax Decision That Matters Most
| Traditional (Pre-Tax) | Roth (Post-Tax) | |
|---|---|---|
| Tax break | Now (deduct contribution) | Later (tax-free withdrawal) |
| Best when | You're in a high tax bracket now | You're early career / low bracket now |
| Income limits | None for contributions | Roth IRA phases out above $161k (single) |
Rule of thumb: If you expect to be in a higher tax bracket in retirement, go Roth. If lower, go Traditional. Most early-career professionals benefit from Roth.
A Real Numbers Example
Sarah is 28, earns $80,000, and her employer matches 50% up to 6%. She can save $15,000/year. Here's the optimal allocation:
| 1. 401(k) to match (6%) | $4,800 + $2,400 match |
| 2. Roth IRA | $7,000 |
| 3. Remaining to 401(k) | $3,200 |
Total invested: $15,000 + $2,400 match = $17,400/year
Over 30 years at 7% return, that's approximately $1.7 million — without a single dollar more.
