The 401(k) gap allows high earners to bypass Roth IRA income limits

High earners can funnel up to $47,500 annually into tax-free Roth accounts, bypassing the income limits that prevent direct Roth IRA contributions. This access to tax-free growth and the absence of minimum distributions is available to those whose 401(k) plans permit both after-tax contributions beyond the standard deferral limit and either in-plan Roth conversions or in-service distributions.
The strategy relies on the gap between two IRS limits for 2026. The employee deferral limit is $24,500, while the total contribution ceiling under Section 415(c) is $72,000. The space between these two figures allows for after-tax contributions. A participant who maxes out their employee deferral and receives no employer match has $47,500 of remaining room under the 415(c) ceiling.
Employer matches reduce this available space. A participant receiving a $10,000 match has approximately $37,500 of remaining after-tax room, as the match counts against the 415(c) ceiling. Once these after-tax contributions are made, they must be converted to Roth status to avoid taxable earnings.
Eligible high earners can funnel up to $47,500 annually into tax-free Roth accounts.
