401(k) vs IRA vs Roth IRA: Which Retirement Account Is Right for You?

Understanding Each Account Type

401(k): Employer-Sponsored Retirement

A 401(k) is a retirement account offered by your employer. Contributions are made with pre-tax dollars, which means you get a tax deduction in the year you contribute. The money grows tax-deferred, and you pay ordinary income tax when you withdraw it in retirement. The big advantages are the high contribution limit ($23,000 in 2026, plus $7,500 catch-up if you are 50 or older) and the employer match — free money from your company, typically 50% to 100% of your contributions up to a certain percentage of your salary. The main disadvantage is limited investment options (you can only choose from your plan's menu of funds) and required minimum distributions starting at age 73. If you leave your job, you can roll your 401(k) into an IRA to gain more investment freedom.

Traditional IRA: Individual Retirement Account

A traditional IRA is an individual retirement account you open yourself through a brokerage like Vanguard, Fidelity, or Schwab. Like a 401(k), contributions are pre-tax and grow tax-deferred, with taxes due on withdrawal. The contribution limit is much lower — $7,000 in 2026 (plus $1,000 catch-up at age 50). The key limitation is income-based deductibility: if you or your spouse have access to a workplace retirement plan, your ability to deduct traditional IRA contributions phases out at certain income levels (starting at $77,000 for single filers in 2026). If you cannot deduct your contribution, a traditional IRA loses its main advantage over a taxable brokerage account. Unlike a 401(k), you have unlimited investment choices — any stock, ETF, mutual fund, or bond available through your broker. Learn how to open an IRA →

Roth IRA: Tax-Free Growth and Withdrawals

A Roth IRA is the most powerful retirement account for most young investors. Contributions are made with post-tax dollars (no deduction now), but all growth and withdrawals are completely tax-free in retirement. This means if you contribute $7,000 per year for 30 years and it grows to $800,000, you pay $0 in taxes on the entire amount. Roth IRAs have no required minimum distributions, so you can let the money grow as long as you want. You can also withdraw your contributions (but not earnings) at any time penalty-free, giving you flexibility in an emergency. The downsides: income limits prevent high earners from contributing directly (phaseout starts at $161,000 for single filers in 2026), and the contribution limit is the same $7,000 as a traditional IRA. There is also a backdoor Roth IRA strategy for high earners, but this requires careful tax planning.

Roth 401(k): The Hybrid Option

Many employers now offer a Roth 401(k) option alongside the traditional 401(k). With a Roth 401(k), you contribute after-tax dollars and withdraw tax-free in retirement — combining the high contribution limit of a 401(k) with the tax treatment of a Roth IRA. Unlike a Roth IRA, there are no income limits for a Roth 401(k), making it the best option for high earners who cannot contribute directly to a Roth IRA. The main catch: employer matching contributions are always pre-tax (traditional), so you will have a mix of tax-free and taxable money at withdrawal. Roth 401(k)s also have required minimum distributions, unlike Roth IRAs, but you can avoid this by rolling your Roth 401(k) into a Roth IRA at retirement.

Contribution Limits and Income Rules for 2026

Should I max out my 401(k) before opening an IRA?

No — the general recommendation is to contribute enough to your 401(k) to get the full employer match (free money), then max out a Roth IRA, then go back to your 401(k). The reason: IRAs offer more investment choices and typically lower fees than 401(k) plans. For example, if your employer matches 50% of contributions up to 6% of your salary, contribute at least 6% to get the full match. Then contribute to a Roth IRA up to the $7,000 limit. If you still have money to save for retirement, increase your 401(k) contribution. This is often called the "retirement savings priority order" and is recommended by most financial advisors.

Can I have both a 401(k) and an IRA?

Yes, absolutely. Having both accounts is common and often the optimal strategy. The contribution limits are separate, so you can contribute the maximum to each if your budget allows. Having both gives you tax diversification — when you retire, you can withdraw from your taxable 401(k) up to the top of your current tax bracket and use your Roth IRA for tax-free withdrawals beyond that, managing your tax bracket year by year. The one restriction: if you have a 401(k) at work, your ability to deduct traditional IRA contributions may be limited by your income. Roth IRA contributions are not affected by workplace plans, only by income limits. Having both accounts also gives you more investment flexibility, since IRAs offer unlimited investment choices while 401(k)s are limited to your plan's fund menu.

What happens if I earn too much for a Roth IRA?

If your modified adjusted gross income exceeds $161,000 (single) or $240,000 (married filing jointly) in 2026, you cannot contribute directly to a Roth IRA. However, there is a legal workaround called the backdoor Roth IRA. You contribute to a traditional IRA (which has no income limits), then convert that contribution to a Roth IRA. Since the contribution was non-deductible (because of your high income), the conversion is essentially tax-free. This strategy is perfectly legal but requires careful paperwork — if you have existing pre-tax IRA balances, the pro-rata rule can make the conversion partially taxable. Most high earners use this strategy annually. A simpler option is contributing to a Roth 401(k) at work, which has no income limits. Compare investment options within your retirement accounts →

When should I choose a Roth over traditional?

Choose a Roth when you expect to be in a higher tax bracket in retirement than you are today. This is usually the case for young professionals early in their careers — your income is relatively low now, so paying taxes now at a lower rate is better than paying later at a higher rate. Choose traditional when you are in a high tax bracket now and expect lower income in retirement. Many retirees fall into a lower bracket because they no longer have earned income. A good rule of thumb: if your marginal tax rate is 22% or lower, prioritize Roth. If you are in the 32% bracket or higher, prioritize traditional. The 24% bracket is a gray area where the right answer depends on your specific situation. Contributing to both accounts gives you tax flexibility in retirement regardless of future tax rates.
