401ks offer employer match and high limits; IRAs offer flexibility and tax options.
A 401k is employer-sponsored with higher contribution limits and potential matching. An IRA is independently opened with lower limits but more flexibility. Ideally, use both: capture the employer match, then max out a Roth IRA.
401k strategy
Contribute to 401k up to employer match (free 3–6% return). Remaining savings go to Roth IRA (flexibility). If still saving, max 401k (2026 limit: $24,500/year).
30-year outcome ($500/month into 401k + $583/month Roth IRA)
| Factor | 401k Only | 401k + Roth IRA |
|---|---|---|
| Annual contributions | $6,000 | $6,000 + $7,000 = $13,000 |
| Employer match (3%) | +$180/year | +$180/year |
| 30-year balance (7% avg return) | ~$750K | ~$1.5M |
| Taxes owed (Traditional 401k) | ~$200K (25% withdrawal) | $0 (Roth is tax-free) |
| Net after taxes | $550K | $1.5M |
When to use 401k
- Your employer offers matching (free money)
- You want to save $15K+ annually (IRA limit too low)
- You're in a high tax bracket now (pre-tax savings valuable)
When to use IRA
- Self-employed or no 401k offered
- You want flexibility (Roth contributions withdrawable anytime)
- You want more investment control
Frequently asked questions
What is a 401k?
An employer-sponsored retirement plan. You contribute pre-tax salary; employer may match (free money). 2026 limit: $24,500/year. Money grows tax-deferred. Employer handles administration. Required withdrawals at age 73 (RMDs).
What is an IRA?
Individual Retirement Account you open independently (Traditional or Roth). 2026 limit: $7,500/year (much lower). Traditional: pre-tax contributions, taxed on withdrawal. Roth: post-tax contributions, tax-free withdrawals. No RMDs for Roth (ever).
Which has the highest contribution limit?
401k: $24,500/year. IRA: $7,500/year (2026 limits). A 401k allows more than 3× the IRA limit. If your employer offers 401k, maximize it first (especially if there's a match).
Should I get the employer match?
Always. If your employer matches 3–6% of salary, that's 3–6% free money. Contribute enough to capture the full match, then consider maxing out a Roth IRA for flexibility.
Which is more flexible?
IRAs are more flexible. Withdraw Roth contributions anytime penalty-free. Traditional IRA withdrawals before 59.5 incur 10% penalty + taxes. 401k: very restrictive (age 59.5, separation, hardship). IRAs win on flexibility.
Which should I prioritize?
1) Contribute to 401k up to employer match (free money). 2) Max out Roth IRA ($7,500 in 2026). 3) Return to 401k if still saving. This balances employer match, flexibility, and tax efficiency.
