The Internal Revenue Service (IRS) has announced 2018 dollar limitations on benefits, contributions, and compensation. The Internal Revenue Code (Code) affords tax benefits for employers that sponsor qualified plans and for employees that participate in such plans. In exchange for these tax benefits, the Code places limitations on the contribution and benefit amounts. The IRS makes annual cost-of-living adjustments (COLAs) to these limits.
The key limits for 2018 (and the limits that applied in 2017) are listed in the table below:
| Code Section | Limit | 2018 | 2017 |
| §402(g)(1)(B) | 401(k)/403(b) Elective Deferrals | $18,500 | $18,000 |
| §457(e)(15)(A) | 457(b) Contributions | $18,500 | $18,000 |
| §414(v)(2)(B)(i) | Age 50+ "Catch-Up" Contributions to 401(k), 403(b), and governmental 457(b) plans | $6,000 | $6,000 |
| §415(c)(1)(A) | DC Annual Additions | $55,000 | $54,000 |
| §415(b)(1)(A) | DB Annual Benefits | $220,000 | $215,000 |
| §414(q)(1)(B)(i) | Highly Compensated Employees | $120,000 | $120,000 |
| §401(a)(17)(A) | Annual Compensation Taken Into Account | $275,000 | $270,000 |
| §416(i)(1)(A)(i) | Key Employee/Officer | $175,000 | $175,000 |
| §223(b)(2) | HSA Annual Contribution Levels | ||
| Individual | $3,450 | $3,400 | |
| Family | $6,900 | $6,750 | |
| Social Security Wage Base | $128,400 | $127,200 |
The most important changes in these limits are as follows:
- For most employees, the most significant change is the increase in the maximum limits for pre-tax and Roth contributions to 401(k), 403(b), and 457(b) plans. These raise the amount that individuals can contribute from $18,000 to $18,500 for employees under 50. The catch-up permits employees 50 and above to contribute up to an extra $6,000, or a total of $24,500 in 2018, to 401(k), 403(b), and governmental 457(b) plans, but not to 457(b) plans of nongovernmental employers. Further catch-ups may be available to participants in certain 403(b) plans.
- The total annual limit on employer and employee contributions ("annual additions") will rise from $54,000 to $55,000. ("Catch-up contributions" described in the preceding paragraph do not apply in calculating this limit, so the annual limit for those age 50 and above can be as high as $61,000.) This will benefit employees in defined contribution plans that provide for after-tax employee contributions, or that include generous employer-provided benefits.
- The limit on annual benefits from defined benefit plans, when taken as a straight life annuity beginning between ages 62 and 65, will increase from $215,000 to $220,000.
- The annual limit on compensation that can be taken into account in calculating contributions and benefits and in performing certain nondiscrimination testing will increase from $270,000 to $275,000 (and will be even higher for certain governmental plans).
- The threshold for determining who is a highly compensated employee will remain at $120,000.
- The threshold for determining whether an officer is a key employee for purposes of the top-heavy rules will remain at $175,000.
- The annual amount that individuals can contribute to health savings accounts, if they are covered by high deductible health plans, will increase from $3,400 to $3,450 in the case of individual coverage, and from $6,750 to $6,900 in the case of family coverage.
- And independently, the Social Security Administration announced that the maximum amount of wages subject to Social Security taxes for 2018 will increase from $127,200 to $128,700.
