SECURE Act 2.0: Retirement Plan Eligibility Changes Now in Effect for Part-Time Workers

Starting in 2025, key provisions of the SECURE Act 2.0 officially take effect, reshaping how many Americans gain access to an employer-sponsored retirement plan. One of the most impactful updates shortens the eligibility timeline for long-term, part-time workers – allowing more employees to participate in a workplace retirement plan sooner than ever before.

Under the updated retirement plan SECURE Act rules, further opportunity to save for retirement through a tax-advantaged savings plan, such as a 401(k), is less the domain of only full-time workers. Instead, the SECURE Act reflects how today’s workforce actually operates, offering broader inclusion and earlier participation.

Part of this reflection to include the current workforce reflects the fact that more age 55+ women are working than before. Many of whom may have taken up part-time work due to high cost of living, desire to remain busy and active, or simply to supplement current retirement investments.

Before continuing, be sure to review our earlier articles covering other major SECURE Act retirement plan changes that also took effect in 2025, including automatic enrollment requirements and expanded catch-up contributions.

This article focuses specifically on the SECURE Act retirement plan eligibility rule for long-term, part-time workers – how it works, who benefits most, and why it matters over time.

What Changed Under the SECURE Act Retirement Plan Rules

Before the SECURE Act, many part-time employees faced limited access to an employer-sponsored retirement plan, even when they worked consistent hours year after year. SECURE Act 1.0 improved access somewhat by allowing long-term, part-time workers to defer into a retirement plan after completing 500 hours of service in three consecutive years.

The SECURE Act 2.0 retirement plan update slightly accelerates that timeline. Beginning in 2025, employees who work at least 500 hours in two consecutive years must be allowed to participate in their employer’s 401(k) or 403(b) retirement plan. This one-year reduction significantly expands retirement plan access and increases the amount of time workers can benefit from tax-deferred growth.

In retirement planning, that additional year can make a measurable difference.

How the SECURE Act Retirement Plan Change Benefits Long-Term Workers

This retirement plan SECURE Act provision is especially impactful for employees who have consistently worked part-time but were previously excluded from employer plans.

A Broader Definition of Retirement Plan Eligibility

Under prior retirement plan rules, even employees working 20–30 hours per week could remain locked out of their company’s retirement plan for years. For workers balancing school, caregiving responsibilities, or multiple jobs, full-time status wasn’t always feasible.

The SECURE Act retirement plan update reduces the eligibility requirement to two consecutive years of 500 hours – less than 10 hours per week on average. This change aligns retirement plan access with modern work patterns.

As a result, eligible workers gain:

• Earlier entry into a workplace retirement plan.
• More years of potential tax-deferred retirement plan growth.
• Greater incentive to remain with an employer offering competitive benefits.

Why Earlier Retirement Plan Access Matters

Earlier access to a retirement plan means more time for contributions to compound. Even modest retirement plan contributions, when started earlier, often outperform larger contributions made later.

This is why the SECURE Act’s retirement plan changes are so impactful – they prioritize timing, not just contribution limits.

What Employers Must Do Under the SECURE Act Retirement Plan Rules

While the SECURE Act retirement plan provisions offer meaningful benefits to employees, they also introduce important responsibilities for employers and plan sponsors.

Mandatory Retirement Plan Amendments

For plan years beginning in 2025, employers sponsoring a retirement plan must allow long-term, part-time employees to make elective deferrals once they complete:

• At least 500 hours of service, and
• Two consecutive years meeting that requirement

This retirement plan eligibility rule is mandatory. Employers may no longer rely on older plan language requiring three years of service for long-term, part-time workers.

Retirement plan documents must be updated accordingly, and eligibility determinations must be applied consistently. Failure to comply can expose employers to correction requirements, penalties, and potential retirement plan qualification issues.

Why the SECURE Act Retirement Plan Update Matters in the Real World

Today’s workforce increasingly relies on flexible schedules, seasonal roles, and part-time positions. Historically, those workers often lacked access to an employer-sponsored retirement plan.

The SECURE Act retirement plan change helps correct that imbalance by:

• Expanding retirement plan access for workers with nontraditional schedules.
• Allowing earned income to support retirement planning earlier.
• Encouraging more inclusive retirement plan designs.

Whether you’re a student, caregiver, or someone who prefers part-time work, the retirement plan SECURE Act provision creates a clearer path toward long-term retirement security.

The Long-Term Retirement Plan Impact of Starting Earlier

Over time, even one additional year of retirement plan participation can provide:

• Increased employer matching opportunities, when offered.
• Increased tax-deferred contribution opportunities.
• Greater time for compounding growth potential over decades.

In retirement planning, consistency and time often matter more than contribution amount.

Why the SECURE Act Retirement Plan Change Deserves Attention

Reducing a retirement plan eligibility requirement from three years to two may seem modest. But, to repeat this important point once more – in retirement planning, when you start saving often matters more than how much you save.

The SECURE Act retirement plan provisions remove a long-standing barrier for workers who were excluded based on schedule – not commitment. For many Americans, that earlier access can materially change retirement outcomes.

If you believe you may qualify under the SECURE Act retirement plan rules, your first step is to confirm your service hours with your HR department or plan administrator. From there, building a budget that supports retirement plan contributions can help you take full advantage of the opportunity.

Not only is saving for retirement largely about timing, but so is how to make the money you’ve worked hard for your life to save last longer in retirement. A retirement income plan ensuring you’re taking the right amount of money from the right income source can minimize taxes, maximize lifetime Social Security income, and preserve your assets so you have more to leave behind.
