Roth IRA vs. 401(k): Which one should you fund first?
Pre-tax today vs. tax-free tomorrow. The right order is usually simpler than the debate makes it sound.
Most personal finance advice tells you to max out your retirement accounts. What it skips is the order, and the order matters more than most people realize.
The short answer most people should follow: contribute to your 401(k) up to the employer match, then fund a Roth IRA to the annual limit if you are eligible, then go back and contribute more to your 401(k). Your income, tax bracket, and timeline can change the answer, but this order is a strong default.
The core difference: when you pay taxes
401(k)
Roth IRA
A traditional 401(k) lowers taxable income today and taxes withdrawals later. A Roth IRA uses money you already paid taxes on, but qualified retirement withdrawals, including growth, can be tax-free. Roth tends to look better when your tax rate is low today and likely higher later. Traditional 401(k) contributions tend to look better when your tax rate is high today and likely lower in retirement.
The numbers you need to know
- 401(k) contribution limit for 2026: $24,500. If you are 50 or older, the standard catch-up contribution is $8,000, for a total of $32,500. Ages 60 through 63 may qualify for a higher catch-up limit.
- IRA contribution limit for 2026: $7,500. If you are 50 or older, the IRA catch-up contribution is $1,100, for a total of $8,600.
- Roth IRA income phase-out for 2026: $153,000 to $168,000 for single filers and heads of household; $242,000 to $252,000 for married filing jointly.
If your income is above the Roth IRA limit, you cannot contribute directly to a Roth IRA, but some people use a backdoor Roth conversion. That is legal, but the tax details matter, especially if you already have pre-tax IRA money.
The employer match is free money
The match may vest over time, which means you may need to stay at the employer for a period before you fully own employer contributions. Know the vesting schedule, but do not ignore the match.
The recommended order for most people
Get the match
Contribute to your 401(k) up to the full employer match.
Fund Roth IRA
Use the Roth IRA if your income allows and it fits your tax picture.
Return to 401(k)
Add more to the 401(k), up to the employee limit.
Taxable brokerage
Use a brokerage account if you still have money to invest.
This sequence captures free money, adds tax-free Roth growth, and still lets you defer taxes on additional income through the 401(k).
When you might flip the order
A traditional 401(k) can beat Roth contributions if you are in a high tax bracket today and expect a lower bracket in retirement. If you are in the 32% or 37% federal bracket, the current deduction has real value. It can also make sense if your 401(k) has excellent low-cost funds, or if you are not eligible for direct Roth IRA contributions.
What about a Roth 401(k)?
Many employers offer a Roth 401(k), which combines 401(k)-level contribution limits with after-tax Roth treatment. There are no Roth 401(k) income limits. If your employer offers it and you want more tax-free retirement income, it is worth comparing against traditional contributions.
The one thing that matters more
How much you save, and how consistently you save it, will usually matter more than perfect account selection. Someone saving 15% of income in a traditional 401(k) is likely to beat someone saving 6% in a Roth IRA while congratulating themselves for making the smarter choice.
Pick a sensible account order, automate contributions, invest in low-cost diversified funds, and leave the money alone.
FAQ
Can I have both a Roth IRA and a 401(k)?
Yes. Many people use both. The key constraints are contribution limits, plan availability, and Roth IRA income eligibility.
What if I am self-employed?
You may have options like a solo 401(k), SEP IRA, SIMPLE IRA, or traditional/Roth IRA. The best fit depends on income, employees, and contribution goals.
Can I withdraw Roth contributions early?
Roth IRA contributions can generally be withdrawn tax- and penalty-free, but earnings have stricter rules. Treat retirement money as retirement money unless you have a real reason.
Should high earners ignore Roth accounts?
Not necessarily. High earners may still use Roth 401(k) contributions or backdoor Roth strategies, but the tax math deserves care.
