Payroll Changes for 2026: What Employers Need to Know About the New Catch-Up Contribution Rules

It’s 2026, and employers and employees alike are now adjusting to the latest payroll and retirement plan changes that took effect at the start of the year. Among the most significant updates are the new catch-up contribution rules for retirement plans, which especially impact high-earning employees aged 50 and over. Understanding these updates is crucial for maintaining compliance and helping your workforce make the most of their retirement planning.

Mandatory Roth Catch-Up Contributions for High Earners

Beginning this year, employees aged 50 or older who earned more than $145,000 (indexed for inflation) in FICA wages from their employer last year are now required to make their catch-up contributions as Roth (after-tax) contributions. Pre-tax catch-up contributions are no longer an option for these individuals.

What does this mean in practice?

• High earners must pay taxes on these contributions now, but can look forward to tax-free withdrawals in retirement.

• This change does not eliminate their ability to make catch-up contributions—it simply alters the tax treatment.

Employers have had to update their payroll and retirement plan systems to support this change. It’s now essential to track employee wages closely to determine eligibility and ensure proper handling of Roth catch-up contributions.

No Catch-Up Contributions for High Earners Without a Roth Option

If your company’s retirement plan does not offer a Roth contribution feature, your high-earning employees are now prohibited from making any catch-up contributions whatsoever. This has prompted many employers, if they hadn’t already, to add Roth options to their plans in the run-up to 2026. If your plan is still missing a Roth option, it’s important to address this immediately to avoid limiting your employees’ retirement savings opportunities.

Standard Catch-Up Limits and Choices for Other Employees

Employees under the $145,000 wage threshold continue to enjoy flexibility. They can make catch-up contributions with either pre-tax or Roth treatment, according to their preference and financial strategy. The annual catch-up contribution limit (currently adjusted for inflation; for 2026, check IRS announcements) still applies to all eligible participants.

Payroll and Reporting Complexity

These changes have introduced new layers of complexity for payroll and HR teams:

• Accurate tracking of employee compensation is essential to identify who must make Roth catch-up contributions.

• Payroll and benefit systems must be capable of distinguishing between regular and catch-up contributions, pre-tax and Roth, and now, between high earners and other employees.

• Regular communication with employees about these changes is a must—especially for those directly affected.

Employers who invested in staff training and system upgrades over the past year are seeing smoother transitions now.

Frequently Asked Questions: 2026 Catch-Up Changes

Who is affected?
Employees age 50+ who earned more than $145,000 in FICA wages from their current employer in the previous calendar year.

How to Support Your Employees

If you haven’t already, make sure your payroll and retirement plan systems are updated to accommodate these new rules. Proactively communicate with all employees, especially those turning 50 this year or earning above the $145,000 threshold, so they understand how their retirement savings options have changed. HR and payroll staff should be well-trained on eligibility requirements and reporting processes.
