IRS Updates U.S. Retirement Plan COLAs for 2018

October 19, 2017

On October 19, 2017, the IRS released its cost-of-living adjustments applicable to tax-qualified retirement plans for 2018.  In contrast to recent years where many limits had remained unchanged, a number of the key limitations for 2018 will increase as follows:


2018 Limit

402(g) Limit on Employee Elective Deferrals (Note:  This is relevant for 401(k), 403(b) and 457 plans, and for certain limited purposes under Code Section 409A.)

$18,500 ($18,000 for 2017)

414(v) Limit on “Catch-Up Contributions” for Employees Age 50 and Older (Note:  This is relevant for 401(k), 403(b) and 457 plans.)

$6,000 (unchanged)

401(a)(17) Limit on Includible Compensation (Note:  This applies to compensation taken into account in determining contributions or benefits under qualified plans.  It also impacts the “two times/two years” exclusion from Code Section 409A coverage of payments made solely in connection with involuntary terminations of employment.)

$275,000 ($270,000 for 2017)

415(c) Limit on Annual Additions Under a Defined Contribution Plan

$55,000 (or, if less, 100% of compensation) ($54,000 for 2017)

415(b) Limit on Annual Age 65 Annuity Benefits Payable Under a Defined Benefit Plan

$220,000 (or, if less, 100% of average “high 3” compensation) ($215,000 for 2017)

414(q) Dollar Amount for Determining Highly Compensated Employee Status

$120,000 (unchanged)

416(i) Officer Compensation Amount for “Top-Heavy” Determination (Note:  Because Code Section 409A defines “specified employees” of public companies by reference to this provision, this amount also affects the specified employee determination, and thus, the group subject to the six-month delay under Code Section 409A.)

$175,000 (unchanged)

Social Security “Wage Base” for Plans Integrated with Social Security

$128,700 ($127,200 for 2017)
