Both are excellent retirement accounts — but the right order of contributions can save you thousands.
Most Americans have access to both a 401(k) through their employer and a Roth IRA they open themselves. Both are excellent retirement vehicles — but they have different tax treatments, contribution limits, and investment options. Knowing the right order to fund them can make a significant difference in your long-term wealth.
A 401(k) is an employer-sponsored retirement plan. In 2026, you can contribute up to $23,500 per year ($31,000 if 50+). Many employers offer a match — contributing 50–100% of your contributions up to a certain percentage of your salary. Traditional 401(k) contributions reduce your taxable income today; Roth 401(k) contributions grow tax-free.
A Roth IRA is opened independently at a brokerage. In 2026, the limit is $7,000/year ($8,000 if 50+). Contributions are after-tax, but all growth and qualified withdrawals are completely tax-free. You have complete control over investments — unlike a 401(k) where you're limited to the plan's fund menu.
If your 401(k) only offers high-fee actively managed funds, still contribute enough to get the full employer match (the match outweighs the high fees). Then prioritize your Roth IRA with low-cost index funds. After maxing the Roth, reconsider more 401(k) contributions — the tax advantages often still outweigh the higher costs.
