You can generally contribute to both a 401(k) and an IRA in the same year, provided you meet each account's requirements. Participating in a workplace plan does not use up your regular IRA contribution allowance.
The part that often changes is the deduction. A worker may be allowed to put money into a traditional IRA without being allowed to deduct all of it. Keeping those questions separate makes the decision much easier to understand.
The accounts have separate limits, with shared limits inside each category
For 2026, the ordinary employee deferral limit for a 401(k) is $24,500. The regular IRA limit is $7,500, or eligible compensation if lower. Age-based additions may apply; our catch-up contribution guide explains the different rules.
Pre-tax and Roth 401(k) deferrals share the workplace employee limit; traditional and Roth IRA contributions share the IRA limit. You do not get another allowance by opening more accounts of the same kind.
For an illustration, a 45-year-old with sufficient eligible compensation could contribute $18,000 to a 401(k) and $5,000 across IRAs without exceeding either basic 2026 limit. Whether the IRA contribution is deductible or permitted as a direct Roth contribution still depends on the relevant income rules.
An employer match does not reduce the employee salary-deferral allowance, although employer and employee contributions face a separate overall plan limit. Also, changing employers generally does not restart your personal 401(k) deferral allowance for the year.
Workplace coverage can reduce a traditional IRA deduction
Being covered by a workplace retirement plan can limit the IRA deduction, rather than prohibit the contribution. Filing status, modified adjusted gross income and a spouse's workplace coverage determine which rules apply.
For example, in 2026 a single taxpayer covered by a workplace plan has a traditional IRA deduction phase-out between $81,000 and $91,000 of modified adjusted gross income. That is a deduction range, not the income range for direct Roth IRA contributions. Married taxpayers have different rules.
Before funding the IRA on the assumption of a tax saving, check your IRA deduction eligibility on the IRS website. If the contribution is nondeductible, keep the required tax records. If considering a Roth instead, our Roth versus traditional IRA comparison explains the separate eligibility question.
Choose the next contribution by what it accomplishes
A worker whose employer offers a match may first want to understand the contribution needed to receive it. Beyond that point, account fees, available investments, tax treatment and access restrictions can all affect where another dollar is most useful.
Having room to contribute does not mean every household should fill every account. Money needed for an imminent bill or emergency reserve belongs in the same planning conversation. The combined legal ceiling is not a personal savings target.
Keep a simple running total for workplace deferrals and another for regular IRA contributions. Record the tax year attached to IRA deposits, particularly when contributing early in the following year. Two clear totals are more helpful than adding every retirement-account deposit together and comparing it with the wrong limit.
