The 401(k) Vesting Rule That Could Make You Lose Your Employer Match When You Leave

The 401(k) Vesting Rule That Could Make You Lose Your Employer Match When You Leave

Before you set a final date for leaving a job, make sure you know how much of your 401(k) is actually yours. The money you put in is always yours, but your employer’s match may be subject to a vesting schedule. Leaving a little too soon could mean walking away from thousands of dollars.

If you are thinking about a new job, find out how much of the match you would forfeit before you accept a start date. Your account total may not show the full picture. Understanding vesting can help you avoid an unwelcome setback to your retirement savings.

Your own contributions are yours right away

“Vesting” refers to ownership. The IRS says you are immediately vested in the money taken from your paycheck and placed into your 401(k), even if you later leave the company.

You do not lose those contributions because you resign after a short time or depart on bad terms. The risk applies to employer contributions that have not yet vested.

Employer matching money may come with a waiting period

A company can deposit matching contributions each payday without giving you immediate ownership. In a traditional 401(k), employer contributions may vest gradually or may become yours right away.

That is why simply seeing a match in your account is not enough. Check your vested balance and then review the breakdown by contribution source. For instance, if your $50,000 balance includes $8,000 in unvested matching funds, only $42,000 is currently yours to keep.

Cliff vesting can make timing crucial

Under cliff vesting, you do not own any of the match until you complete the required service period. After that, you own the full amount. A traditional 401(k) using this method generally must fully vest matching contributions after no more than three years, although a plan can require less time.

If your plan follows that three-year schedule, leaving just before you hit the requirement could cause you to lose the entire unvested match. Under a cliff schedule, being close does not earn partial ownership.

Graded vesting builds ownership over time

Graded vesting allows you to keep a larger share of the match as your service increases. Under the IRS’s six-year schedule, you are 20% vested after two years, 40% after three, and fully vested after six. The schedule works like this:

Completed years of serviceEmployer match you own
Less than 20%
220%
340%
460%
580%
6 or more100%

Some employers use a faster schedule, so do not assume these percentages apply to your plan without checking.

Leaving a few months early can be expensive

Imagine you have $9,000 in employer matching contributions under a three-year cliff schedule, and your plan administrator says you still need three months of service to keep it.

If you quit now, that $9,000 could be forfeited. If you stay long enough to complete the service requirement, you keep the match. This example does not include investment gains, losses or new contributions, but the point is simple: Is leaving early worth giving up $9,000?

Your work anniversary may not be the vesting date

Do not assume that three calendar years automatically means you have reached your vesting date. Plans can use different ways to count service.

The IRS says a year of service generally means 1,000 hours over a 12-month period, but your plan’s own rules control the calculation. Ask your plan administrator how much service has been credited to you and when you will reach the next vesting level. It may not match your work anniversary.

Waiting to move your 401(k) does not make unvested money yours

You usually do not gain extra vesting credit simply by leaving your 401(k) with a former employer. If you leave before meeting the service requirement, waiting longer to roll over the account does not count as extra employment.

The IRS says forfeiture can occur when your balance is paid out or after certain breaks in service. Unvested money may still appear in your account for a while, but that does not mean you have earned it. Ask about the plan’s forfeiture rules and what happens if you are rehired.

Some plans vest employer money immediately

Your plan may have no waiting period at all. In a traditional safe harbor 401(k), required matching contributions generally vest immediately.

Still, do not assume “safe harbor” means every employer contribution is yours right away. A qualified automatic contribution arrangement, or QACA, may require up to two years of service. Additional matching contributions may follow a separate schedule. Find out which rules apply to your account.

Check the numbers before you resign

Request your Summary Plan Description, which outlines the vesting rules for your plan. Then ask the administrator to confirm:

  • Your current vested balance.
  • The amount you would forfeit if you left on your planned date.
  • When you will reach the next vesting level.

Get the answer in writing and keep it with your statement. If the numbers do not match what your account shows, sort out the discrepancy before relying on either figure.

The bottom line

Before you quit, check how much of your employer match is vested and what you would lose by leaving. A few months can make a big difference, but staying may not be worth turning down a better opportunity. Knowing the dollar amount helps you make the right decision with the full picture in mind.

Even if you plan to stay, mark your next vesting milestone on your calendar. Include the amount at stake and a reminder to verify it with your plan administrator. That way, you will have one less thing to sort out if an unexpected offer comes along.
