Marsh projects 2027 retirement plan limits 

September 14, 2026

Every key Internal Revenue Code (IRC) limit for qualified retirement plans will rise from 2026 to 2027, according to projections by Marsh People and Investments. The 2027 limits will reflect increases in the Consumer Price Index for All Urban Consumers (CPI-U) from the third quarter of 2025 to the third quarter of 2026.

Marsh’s estimates are determined using the tax code’s cost-of-living adjustment and rounding methods, the CPI-U through August, and estimated CPI-U values for September. Figures can’t be finalized until after September CPI-U values are published in October. IRS usually announces official limits for the coming year in late October or early November.

The table below shows our projections of the 2027 limits along with the actual 2026 amounts for comparison: 

IRC retirement plan limit Projected
2027
2026
401(k), 403(b), and eligible 457 plan elective deferrals (and designated Roth contributions)  $25,500§ $24,500
414(v)(2)(B)(i) catch-up contributions for employees ages >=50*    
For employees ages 60‒63 11,750 11,250
For all other employees 8,500§ 8,000
414(v)(7)(A) FICA wage threshold for Roth catch-up mandate $155,000 $150,000
415(b) defined benefit plan annuity 300,000 290,000
415(c) defined contribution plan annual addition 75,000 72,000
401(a)(17) and 408(k)(3)(C) compensation 375,000 360,000
414(q)(1)(B) highly compensated employee (HCE) and 414(q)(1)(C) top-paid group 170,000 160,000
416(i)(1)(A)(i) officer compensation for top-heavy plan key employee 240,000/
245,000§§
235,000

* Different limits apply to SIMPLE plans.

Employees are subject to the Roth catch-up mandate in 2027 if their 2026 FICA wages exceed $155,000.

The HCE limit shown for a year is applied to compensation for that plan year to determine if an employee is an HCE for the following plan year, e.g., an employee with 2027 plan year compensation greater than $170,000 may be an HCE for the 2028 plan year.

§ If September inflation is very low (less than 0.034%), this limit will be $500 lower

.§§ The limit will be the higher amount if September inflation is at moderate levels (higher than 0.35%).
