When it comes to retirement accounts, most people know they should be using them — but far fewer know which account to prioritise or why. The 401(k) vs Roth IRA debate is one of the most common questions in personal finance, and the answer depends on a few key factors specific to your situation.

The short answer: Get the full employer 401(k) match first (it's free money you should never leave on the table), then max out a Roth IRA, then go back to the 401(k). But your specific tax situation may change this order.

How each account works

A 401(k) is an employer-sponsored retirement account. Contributions are made pre-tax, reducing your taxable income today. Your investments grow tax-deferred. When you withdraw in retirement, you pay income tax on withdrawals. In 2026, you can contribute up to $23,500/year ($31,000 if 50+).

A Roth IRA is an individual retirement account funded with after-tax money. You get no tax break today, but your money grows tax-free and withdrawals in retirement are completely tax-free. In 2026, the limit is $7,000/year ($8,000 if 50+), subject to income limits.

The employer match: the most important factor

If your employer matches 401(k) contributions — even partially — contribute enough to capture the full match before doing anything else. A 100% match on up to 3% of salary is an instant 100% return on your money. Nothing else in investing compares. Skipping this is one of the most expensive financial mistakes people make.

When to prioritise the Roth IRA

  • You're early in your career and expect to earn significantly more in the future
  • You're currently in a low tax bracket (under $47,150 for single filers in 2026)
  • You want tax-free income in retirement (especially valuable if you expect tax rates to rise)
  • You want flexibility — Roth contributions (not earnings) can be withdrawn anytime without penalty

When to prioritise the 401(k)

  • You're in a high tax bracket now and want to reduce your taxable income today
  • You expect to be in a lower tax bracket in retirement
  • Your employer offers a Roth 401(k) option (best of both worlds)
  • You want to contribute more than the Roth IRA limit allows

The recommended order of operations

  1. Contribute enough to your 401(k) to capture the full employer match
  2. Max out your Roth IRA ($7,000/year)
  3. Return to your 401(k) and increase contributions toward the $23,500 limit
  4. After maxing both, consider a taxable brokerage account

Both or either? You can contribute to both a 401(k) and a Roth IRA in the same year, as long as you're within the Roth income limits. Most financial planners recommend doing exactly this for maximum tax diversification in retirement.

Key takeaways

  • Always capture the full employer 401(k) match — it's free money
  • Roth IRA is better if you're young or in a low tax bracket now
  • 401(k) is better if you're in a high tax bracket and want today's deduction
  • You can (and often should) use both in the same year
  • Recommended order: 401(k) match → Roth IRA → 401(k) max
