Check Your Eligibility Now401(k) Eligibility Works for Part-Time Employees
| Rule | Requirement |
|---|---|
| Age | 21 or older |
| Hours | 500+ hours per year |
| Service | 2 consecutive years |
| Contributions | Must generally be allowed to make 401(k) contributions |
| Employer match | May have separate eligibility rules |
| Plan rules | Employer can offer earlier eligibility |
Plans may exclude employees who fail these requirements.
So, plans cannot exclude a part-time employee who meets the LTPT test.
These long-term part-timers must be offered the opportunity to make elective deferrals as of the entry date after satisfying the 3-year or 2-year rule.
But plans can still exclude them from employer matches or testing, and may ignore hours worked before the start of the SECURE Act.
When Can a Part-Time Employee Start Contributing?
Once a part-time employee meets the eligibility requirements, they may begin participating and making contributions on the plan’s next entry date.
So, if you are eligible, you can enter no later than the earlier of: the first day of the next plan year following eligibility, or six months after meeting eligibility.
Plans often have monthly or quarterly entry dates.
| When | What It Means |
|---|---|
|
Year 1
|
Work 500+ hours → You complete your first qualifying year. |
|
Year 2
|
Work 500+ hours again → You complete your second qualifying year. |
|
After Year 2
|
You may now qualify for the 401(k) if you meet the other requirements. |
|
Plan Entry Date
|
You can start making your own 401(k) contributions when the plan allows you to enter. |
For example, if an employee becomes eligible on 1 April, they might enter on 1 May or 1 July, depending on plan terms.
Will Part-Time Employees Get an Employer 401(k) Match?
Not necessarily, but it depends on the plan.
A part-time employee may receive an employer 401(k) match, but it depends on the plan’s rules.
The special long-term, part-time rules generally require the employee to be allowed to make 401(k) contributions, but they do not require the employer to provide matching or nonelective contributions to that employee.
- Employer match: Not automatically required for LTPT employees.
- Employer choice: Employers can choose to provide a match to LTPT employees.
- Match formula: If a match is offered, the plan’s matching formula determines how much the employee receives.
- Safe-harbor plans: Special rules may allow LTPT employees to be excluded from certain required safe-harbor contributions.
- Vesting: Employer contributions may be subject to the plan’s vesting rules.
- Plan documents: The Summary Plan Description should explain whether part-time employees qualify for an employer match.

See Your OptionsWho Can Still Be Excluded From a 401(k)?
Even with LTPT coverage expanding, certain exclusions remain allowable under the tax code.
Employers can still continue excluding:
| Permissible Exclusion | Explanation |
|---|---|
| Union employees | Employees covered by a qualifying collective bargaining agreement may be excluded. |
| Nonresident aliens | Certain nonresident aliens with no U.S.-source earned income may be excluded. |
| Other IRC §410(b)(3) employees | Certain employees specifically excluded under the tax code may remain excluded. |
| Student employees | Certain bona fide student employees may be excluded under applicable rules. |
| Under age 21 | Employees who have not reached the applicable minimum age may remain excluded. |
| Doesn’t meet LTPT requirements | Employees who don’t work 500+ hours in each of two consecutive years don’t qualify through the LTPT pathway. |
Yes, there is 401(k) access for many part-time workers, but they don’t cover everyone.
Federal law still allows certain exclusions, including qualifying union employees and nonresident aliens.
Part-Time vs. Full-Time 401(k) Eligibility
Traditional eligibility generally uses the 1-year/1,000-hour rule, while LTPT rules provide a separate path for employees who work at least 500 hours in the required consecutive 12-month periods.
| Criteria | Full-Time | LTPT |
|---|---|---|
|
Age
|
21 or older | 21 or older |
|
Service

Notes: Year of service definitions may vary by plan. If a plan uses the elapsed-time method, employees become eligible after the stated time period regardless of hours, making the 500‑hour rule moot.
Do 401(k)s Count Toward Net Worth and HNW Status?
Yes. A 401(k) is an asset and generally counts toward your total net worth. Net worth is your assets minus your liabilities.
Yes. Under the SEC’s current net-worth test, retirement accounts can be included when calculating net worth. The $1 million threshold excludes your primary residence, not your 401(k) or IRA.
It depends on how HNW is defined. A $1 million 401(k) can make you a millionaire by total net worth, but firms that use investable assets may exclude retirement accounts or treat them differently because they are less liquid.
No. A 401(k) loan does not increase your net worth. You receive cash but also take on a repayment obligation, so the loan itself does not create additional wealth.
Yes. Traditional IRAs, Roth IRAs, and 401(k)s generally count as assets when calculating total net worth. Their liquidity and tax treatment can differ, however.
Yes. Net-worth and HNW definitions can vary by country, institution, and purpose. The rules discussed here are based on U.S. standards, so check the applicable local rules if you live elsewhere.
