IRS Forecasts Possible 401(k) Contribution Increase for 2027

Early 2026 forecasts suggest the Internal Revenue Service may raise the 401(k) contribution limit for 2027. Actuarial firms such as Milliman have updated their projections monthly, using the latest Consumer Price Index figures.

The potential increase would allow workers to set aside more pre‑tax dollars for retirement savings. Historically, the IRS announces official limits in the fall, but market participants are already adjusting their financial plans.

Financial advisers recommend reviewing contribution strategies to maximize the benefit of any forthcoming change. The anticipated adjustment reflects ongoing efforts to keep retirement savings in line with inflation.

Employers and employees alike will need to update payroll systems should the new limit be confirmed.
