Are You Vested in Your 401(k)? What It Means and How to Tell

If you've looked at your 401(k) statement and seen both a "total balance" and a "vested balance," you've run into vesting, and wondered how much of the money is actually yours. This guide answers that in plain English: what being vested means, how to read your vested balance, and exactly when your employer's contributions become yours to keep.

What Does "Vested" Mean in a 401(k)?

In a 401(k), being "vested" means you own the money in your account. It's yours to keep even if you leave your job. You are always 100% vested in the money you contribute yourself; vesting rules only apply to certain contributions your employer makes for you.

Think of vesting as ownership that you earn over time. Your own contributions are yours from the moment they leave your paycheck. Some employer contributions, on the other hand, may only become fully yours after you've worked a certain number of years, and until then, you could forfeit the part you haven't earned if you leave.

What is a Vested Balance?

Your vested balance is the portion of your 401(k) account that you own right now. It's the amount you would keep if you left your job today. It can be lower than your total balance, because some employer contributions may not be fully vested yet.

On most 401(k) statements you'll see two numbers. Your total (or account) balance is everything in the account, including employer money you haven't fully earned. Your vested balance is what's truly yours: your own contributions plus the vested share of your employer's contributions. If the two numbers match, you're fully vested; if your vested balance is lower, the difference is employer money you'll earn by staying longer (or forfeit if you leave first). When you take a loan, rollover, or withdrawal, it's the vested balance that counts.

What Does "Fully Vested" Mean?

Being "fully vested" means you own 100% of your 401(k) account. Every dollar, including all employer contributions, is yours to keep no matter when you leave. Once you're fully vested, your employer can never take back any part of your balance.

You can become fully vested in two ways: by completing enough years of service to reach 100% on your plan's vesting schedule, or automatically through certain events, like reaching your plan's normal retirement age or your employer ending the plan. We cover both below.

What is a Vesting Schedule?

A vesting schedule is the timetable in your plan that determines how much of your employer's contributions you own based on your years of service. The longer you stay, the greater your vested percentage, until you reach 100%.

The tax code sets two maximum schedules, the slowest an employer is allowed to make you vest in a 401(k) or profit sharing plan:

• • Three-year cliff. You're 0% vested until you complete three years of service, then jump straight to 100%.

• • Two- to six-year graded. Your vested percentage climbs 20% a year, starting after two years and reaching 100% after six.

Your employer can always choose a more generous (faster) schedule than these, and many vest employer money immediately, but never a slower one. To find your plan's schedule, check your Summary Plan Description (SPD) or ask your HR or plan administrator.

Does Vesting Apply to Each Year's Contribution?

No. Your vested percentage is based on your total years of service, and it applies to all of your employer contributions at once, not to each year's contribution separately.

So once you reach 100% on your plan's schedule, every employer contribution is yours, no matter which year it was made. And if you're only partway there, say 60% vested, you're 60% vested in your entire employer-contribution balance.

Which 401(k) Contributions are Always 100% Vested?

The money you put into your 401(k) yourself is always 100% vested immediately. That includes your pre-tax and Roth salary deferrals, any after-tax contributions, and money you roll in from another plan. Classic safe harbor employer contributions must also be fully vested right away.

So a vesting schedule can only ever apply to certain employer contributions: usually a discretionary match or profit sharing contribution, or the safe harbor contributions in a QACA plan (a safe harbor plan with automatic enrollment), which can carry a short schedule of up to a two-year cliff. Everything below, by contrast, is always fully yours from day one:

• • Your salary deferrals. The pre-tax or Roth money you choose to contribute from your paycheck.
  • Your after-tax and rollover contributions. Money you add yourself or bring in from a previous employer's plan or an IRA.
  • Classic safe harbor contributions. A special type of employer contribution that must be immediately vested by law.

What Events Make You Fully Vested?

Certain events make you 100% vested no matter where you are on your vesting schedule, most commonly reaching your plan's normal retirement age or your employer terminating the plan. When one of these happens, all of your employer contributions immediately become yours to keep.

The events that trigger full vesting are:

• • Reaching Normal Retirement Age. The retirement age defined in your plan document. It can't be later than the later of age 65 or your fifth anniversary in the plan.
  • Plan termination. If your employer ends the plan (or permanently stops contributing), everyone becomes fully vested in the contributions already made.
  • Reaching an Early Retirement Age. If your plan offers one and you meet it.

Many plans also fully vest you if you leave because of death or disability, though this one is optional. Your plan document will tell you whether it applies.

How is 401(k) Vesting Calculated?

Vesting is measured in years of vesting service. Depending on your plan, you earn a year either by working at least 1,000 hours in a year (the hours-of-service method) or simply by staying employed for the year (the elapsed-time method), regardless of hours.

A couple of details matter. Vesting service counts your time with the employer, not just the time you've been contributing to the plan, and your plan can (within IRS limits) disregard some service, such as years you worked before age 18.

What Happens to Your Unvested 401(k) Money when You Leave?

If you leave your job before you're fully vested, you keep 100% of your own contributions and your vested share of the employer contributions, and you forfeit the rest. The unvested portion goes back to the plan; it doesn't follow you.

For example: suppose you have $1,000 of employer contributions in your account and you're 60% vested when you leave. You keep $600, and the remaining $400 is forfeited back to the plan. (Your own contributions and rollovers are always 100% yours on top of that.)

Forfeited money is typically used to pay plan expenses, reduce the employer's future contributions, or be shared among the remaining participants. The practical takeaway: before you leave a job, it's worth knowing your vested percentage, because staying a little longer can sometimes mean keeping significantly more.

Do Vesting Schedules Apply to the Money You Contribute Yourself?

No. The money you contribute from your paycheck, whether pre-tax, Roth, or after-tax, plus anything you roll in from another account, is always 100% yours immediately. Vesting schedules only ever apply to certain employer contributions.

How to Find Out if You're Vested

To check your own vesting status, look at your 401(k) statement for a "vested balance," read the vesting section of your Summary Plan Description (SPD), or simply ask your HR department or plan administrator what your current vested percentage is. It's a quick answer, and it's worth knowing, especially if you're thinking about changing jobs.
