RS Announces 2018 Retirement Plan Dollar Limits and Thresholds

IRS Notice 2017-74 (Oct. 19, 2017); SSA Fact Sheet: 2018 Social Security Changes (Oct. 13, 2017)

The IRS has announced the 2018 dollar limits and thresholds for retirement plans, which reflect the latest cost-of-living adjustments.  Here are those most relevant to 401(k) plans:

  • Annual Additions. The limit on annual additions (i.e., contributions) to 401(k) and other defined contribution plans will increase to $55,000 (up from $54,000). Code § 415(c)(1)(A).
  • Compensation. The annual limit on compensation that can be taken into account for contributions and deductions will increase to $275,000 (up from $270,000). Code §§ 401(a)(17) (for 401(k) and other qualified plans), 404(l) (for deductions), 408(k)(3)(C) (for simplified employee pension plans (SEPs)), and 408(k)(6)(D)(ii) (for salary reduction simplified employee pension plans (SARSEPs)).
  • Elective Deferrals. The annual limit on elective deferrals will increase to $18,500 (up from $18,000) for 401(k), 403(b), and 457 plans, as well as SARSEPs, and will remain at $12,500 for SIMPLE plans and SIMPLE IRAs. Code §§ 402(g)(1), 457(e)(15), and 408(p)(2)(E).
  • Catch-Up Contributions. The annual limit on catch-up contributions for individuals age 50 and over remains at $6,000 for 401(k) plans, 403(b) contracts, 457 plans, and SARSEPs, and at $3,000 for SIMPLE plans and SIMPLE IRAs. Code § 414(v)(2)(B).
  • HCE. The threshold for determining who is a “highly compensated employee” (HCE) remains at $120,000. Code § 414(q)(1)(B).
  • Key Employee. The threshold for determining whether an officer is a “key employee” under the top-heavy rules (as well as the cafeteria plan nondiscrimination rules) remains at $175,000. Code § 416(i)(1)(A)(i).
  • SEP Participation. The threshold for determining participation in a SEP or SARSEP remains at $600. Code § 408(k)(2)(C).
  • Saver’s Tax Credit. The upper income limit for determining whether certain individuals are eligible for the saver’s tax credit (also known as the retirement savings contributions credit) will increase to $63,000 (up from $62,000) for married filing jointly; will increase to $47,250 (up from $46,500) for head of household; and will increase to $31,500 (up from $31,000) for all other taxpayers. For individuals whose adjusted gross income is below those thresholds, there are also some adjustments to the income levels that trigger a change in the percentage used to calculate the credit. Code § 25B.

The IRS has also announced that the amounts for determining who is a “control employee,” a classification relevant to the valuation of company car benefits, will increase to $110,000 for officers and $220,000 for other employees. Separately, the Social Security Administration (SSA) has announced that the Social Security taxable wage base for 2018 (i.e., the taxable maximum) will increase to $128,700 (up from $127,200).

Comment: Plan sponsors, administrators, and advisors will want to carefully note when the new limits and thresholds apply. Employee communications, plan procedures, and administrative forms should be reviewed and updated as necessary to reflect these changes.
