How a New IRS Ruling Could Affect 401(k) Matching Contributions

Employer-sponsored 401(k) plans provide employees with an extraordinary opportunity to build significant nest eggs for retirement through pretax payroll deferrals. To sweeten the pot, many employers choose to make matching contributions based on a percentage of employees' pay.

A new IRS private letter ruling may make matching contributions even more attractive to employees. In the letter (PLR 202434006), the IRS says 401(k) plan participants can allocate matching contribution funds to other tax-favored accounts offered by their employers. Private letter rulings technically apply only to the parties requesting them, but they also indicate how the IRS would rule under similar circumstances. So the IRS's position here could be considered a harbinger of things to come.

401(k) Matching Contributions

Generous Deferral Limits

Employees who choose to participate in an employer's 401(k) plan can defer part of their salaries to their plan accounts. Contribution limits are adjusted annually for inflation. For 2024, the deferral limit is $23,000, plus an additional $7,500 catch-up contribution for employees age 50 or older.

In addition, you may offer employees matching contributions up to a stated percentage of their salaries. It's common for employers to match 50% of the first 6% of salary deferred by employees, or 3% of employees' salaries. Matching contributions aren't subject to current tax.

All pretax contributions are invested in employees' accounts. Usually, employers offer a range of mutual fund and other investment options to enable participants to build diversified portfolios. Earnings within accounts are allowed to compound without current tax erosion until employees start making withdrawals (typically in retirement). At that point, distributions are taxed at ordinary income tax rates.

4 Options

The recent IRS private letter ruling gave the requesting employer's workers new options. They're now allowed to make annual elections for matching contributions for the forthcoming year to be deposited in one or more of the following:

  1. 401(k) or similar plan. Besides traditional 401(k) plans, defined contribution plans that allow matching contributions include Savings Incentive Match Plans for Employees (SIMPLEs). The deferral limit for SIMPLEs in 2024 is $16,000 or $19,500 for employees age 50 or older.
  2. Health savings account (HSA). Employees who choose a high deductible health plan can opt to participate in their employer's HSA. These accounts can help pay qualified health care expenses without any current tax. In 2024, contribution limits are $4,150 (increasing to $4,300 in 2025) for individual coverage and $8,300 ($8,550 in 2025) for family coverage.
  3. Retiree health reimbursement arrangement (HRA). Employees eligible to sign up for these accounts generally must be age 55 or older and have 10 years of service. Retiree HRA reimbursements for health care expenses are tax-exempt up to an annual limit. The 2024 limit is $6,150 for single coverage and $12,450 for family coverage. For 2025, the limits are $6,350 and $12,800, respectively.
  4. Student loan reimbursement through an educational assistance plan (EAP). If employees participate in an EAP, there's no tax on student loan reimbursements to them. Tax-free EAP benefits are limited to $5,250 annually for 2024 and 2025.

Upsides, Downsides and Need-to-Knows

The option to contribute funds to a variety of tax-advantaged plans is generally welcomed by employees and there are typically few downsides for employers. In fact, adopting a program for matching funds could be a cost-effective decision. Assuming your company already has a 401(k) plan in place, new administrative costs would be relatively small.

However, if you don't already offer an HSA, HRA or EAP, you might incur fees to implement them. And the program will likely add some complexity to administration — particularly if you need to work with different vendors. In addition, be careful to ensure nondiscrimination requirements are met for participation in your 401(k) and any newly adopted plans.

Also keep in mind that employees will require guidance, especially those who've been relatively hands-off in 401(k) plan participation. Carefully communicate your program to workers so they fully understand it as a valuable employee benefit and know when and how to allocate matching funds.

Not Final Yet

It's important for your company to watch for new developments related to matching fund programs. In a similar scenario, Congress codified a provision on student loan debt after it was initially approved in an IRS letter ruling. But it took several years for the student loan debt provision to become law. A new matching fund program could go through the same process, but hopefully it will find a shorter, straighter path to enactment. Contact us with any questions about employee benefits.
