401(k) vs IRA: Which Retirement Account Should You Use First?

The wrong order can cost you thousands in unnecessary taxes. Here's the exact priority: 401(k) match → IRA → back to 401(k) → taxable.

The Exact Priority Order

1. 401(k) up to the match

If your employer matches 50% of contributions up to 6%, putting in 6% gets you an instant 50% return — plus tax savings. Nothing beats free money.

2. IRA (Roth or Traditional)

IRAs give you full control — any fund, any broker, no employer restrictions. Typically lower fees than 401(k)s. Fund this after capturing the match.

3. Back to 401(k) until maxed

Once the IRA is full ($7,000), go back to the 401(k). The $23,500 limit gives you room to save 15-20% of most incomes.

4. Taxable brokerage

Only after all tax-advantaged space is used. Still valuable — just less tax-efficient.

$1,000,000Free money over 30 years: 6% match on $70K salary, invested at 8%

The Match: Your Employer Is Handing You a Raise

A 50% match on 6% means for every $100 you contribute, your employer adds $50 — up to 3% of your salary. On a $70,000 salary, that's $2,100/year in free money. Invested at 8% over 30 years: $257,000 from employer contributions alone. Not maxing the match is literally turning down part of your compensation.

Roth vs Traditional: Which IRA Is Right for You?

FactorChoose TraditionalChoose Roth
Current tax bracket22% or higher12% or lower
Expected retirement bracketLower than nowSame or higher
Age40+ (less time to compound tax-free)Under 35 (decades of tax-free growth)
Need the deduction now?Yes — lowers AGINo — can afford the tax bill

For most early-career earners (22% bracket or lower), Roth is the better long-term play. Paying tax on the seed is better than paying tax on the harvest. A 25-year-old putting $7,000/year into a Roth IRA at 8% for 40 years withdraws $1.68 million completely tax-free. The same amount in Traditional would owe income tax on every withdrawal.

Roth IRA Income Limits (2026)

If you earn too much, you can't contribute directly to a Roth IRA. But you can use the Backdoor Roth:

  1. Contribute to a Traditional IRA (non-deductible)
  2. Immediately convert it to Roth
  3. No income limits apply to conversions

One catch: if you have existing Traditional IRA balances, the pro-rata rule may trigger taxes. Consult a tax professional before attempting a backdoor Roth.

Key Takeaways

  • Priority order: 401(k) match → IRA → 401(k) max → taxable
  • Employer match is instant 50-100% return — never leave it on the table
  • Roth wins for early-career (22% bracket or lower), Traditional wins for peak-earning years
  • IRAs have better fund choices and lower fees than most 401(k)s — fund them second
  • $23,500 + $7,000 = $30,500/year in tax-advantaged space for most workers
