The 401(k) allows significantly higher contributions than an IRA. In 2026, you can defer up to $23,500 into a 401(k) compared to just $7,000 in an IRA. For those aged 50 and older, the 401(k) catch-up brings the total to $31,000 versus $8,000 for the IRA. This higher ceiling makes the 401(k) essential for aggressive retirement savers who want to shelter more income from taxes.
Perhaps the single greatest advantage of a 401(k) is employer matching contributions. A typical match might be 50% of your contributions up to 6% of salary, which is essentially free money added to your retirement. No IRA offers any form of matching. Financial advisors universally recommend contributing at least enough to capture the full employer match before funding other accounts.
While a 401(k) restricts you to a menu of funds chosen by your employer and plan administrator, an IRA lets you invest in virtually any stock, bond, ETF, or mutual fund available on the market. This freedom allows you to build a more tailored portfolio, choose lower-cost index funds, and avoid the high-fee options that plague many 401(k) plans.
Many 401(k) plans carry administrative fees, fund expense ratios above 0.5%, and revenue-sharing charges that eat into returns. IRAs at discount brokerages routinely offer index funds with expense ratios below 0.05% and no account fees. Over a 30-year career, the fee difference alone can amount to tens of thousands of dollars in lost growth.
The 401(k) and IRA are not an either-or choice for most people. The optimal strategy in 2026 is to contribute enough to your 401(k) to capture the full employer match, then fund an IRA for its lower fees and broader investment selection, and finally return to the 401(k) to maximize your total tax-advantaged savings. Together, you could shelter over $30,000 per year from taxes. The key is to start early, contribute consistently, and keep investment costs low across both accounts.
