Can You Contribute to Both a Traditional IRA and a 401(k)?

Yes, You Can Do Both

Yes, you can contribute to both a traditional IRA and a 401(k) in the same year. There is no rule that prevents you from funding both accounts, and doing so can be a smart way to stack tax-deferred savings. The key constraints are the annual contribution limits, any income thresholds that affect deductibility, and whether your employer plan offers a match.

2024 Contribution Limits

The IRS sets separate caps for each account type. For 2024, the 401(k) limit is $23,000, or $30,500 if you are age 50 or older. The traditional IRA limit is $7,000, or $8,000 with catch-up contributions. These limits apply independently, so you can max out both if you wish, as long as your earned income covers the total.

Deductibility and Income Limits

Your ability to deduct traditional IRA contributions depends on your income and whether you or a spouse are covered by a workplace retirement plan. For 2024, the full deduction phases out for single filers with a modified adjusted gross income between $77,000 and $87,000, and for joint filers between $123,000 and $143,000. If you are covered by a 401(k) at work, the IRA deduction may be reduced or eliminated entirely, depending on your filing status and income.

Roth vs. Traditional Considerations

If your income exceeds the deductible IRA limits, you can still contribute to a Roth IRA (subject to separate income limits) or a non-deductible traditional IRA. A non-deductible traditional IRA does not provide a tax deduction today, but it can be a useful vehicle for a backdoor Roth conversion. The 401(k) does not have the same income-based deduction rules, which makes it a valuable complement to an IRA.

Who Should Do Both

Contributing to both accounts makes sense when you want to maximize tax-deferred growth and have enough cash flow to fund multiple accounts. It is especially useful if your employer 401(k) match is limited or if you want more investment options than your plan provides. Tracking your contributions and earned income helps you stay within the IRS limits and avoid excess contribution penalties.
