I’m Quitting My Job — What Happens to My 401(k) Loan and Unvested Match?

You accepted a new job. Congrats!

Now you’re working through everything that comes with leaving the old one.

And then you remember:

I still have a 401(k) loan.

Or maybe you checked your account and saw that some of your employer match is “unvested.”

So, how much of your 401(k) actually comes with you?

Here’s what to check before your last day.

What happens to your 401(k) when you quit?

Start with the good news: the money you contributed to your 401(k) is yours.

You don’t lose it because you change jobs.

Employer contributions can be different. And a 401(k) loan still needs to be dealt with.

Here’s the quick version:

Before you give notice, find two numbers:

Your vested 401(k) balance and your outstanding 401(k) loan balance.

Those two numbers will tell you a lot about what happens next.

What happens to unvested 401(k) money when you quit?

Your own 401(k) contributions are always 100% vested.

In plain English: they’re yours.

The IRS confirms this in its 401(k) vesting guidance.

Employer contributions may work differently.

Some are yours immediately. Others become yours over time through a vesting schedule.

Vesting is just a fancy word for ownership.

Here’s a simple example:

Your employer has contributed $12,000 to your 401(k), and you’re 60% vested.

• $7,200 is yours — that’s the 60% you’ve earned
• $4,800 is still unvested — leaving now could mean giving up that money

Check your next vesting date before you leave

This is easy to overlook.

You might be only a few weeks away from your next vesting milestone. Staying until that date could mean keeping more of your employer’s contributions.

That doesn’t mean a vesting date should decide whether you take a great new job.

It means you should know how much money is at stake before you choose your last day.

Can’t find your vested balance? Ask HR or your 401(k) provider:

“What is my vested balance today, and when is my next vesting milestone?”

What happens to a 401(k) loan when you quit?

Your 401(k) loan doesn’t disappear when you leave.

You still owe the money.

What happens next depends on your plan.

Some plans may allow you to keep making payments after you leave. Others may require repayment.

The IRS notes that a plan may require you to repay a 401(k) loan in full when you leave your job. You can read more in the IRS guide, Considering a loan from your 401(k) plan?.

Before your last day, ask your 401(k) provider:

“What happens to my loan when my employment ends?”

Don’t assume. Get your plan’s actual rule.

What Happens When You Don’t Repay the Loan?

This is where a 401(k) loan can become a tax problem.

Your plan may eventually offset the unpaid loan against your 401(k) account. When that happens:

• The unpaid balance may become taxable income
• You may also owe a 10% additional tax if you’re under age 59½, unless an exception applies

Here’s a simple example:

You leave your job with $10,000 remaining on your 401(k) loan and the loan is eventually offset.

That could mean:

• $10,000 is added to your taxable income
• $1,000 in additional tax if the 10% early distribution tax applies
• Plus the regular income taxes you may owe on that $10,000

That’s why it’s worth understanding your loan options before you leave your job.

Before you quit, check these 5 things:

Give your 401(k) ten minutes before your last day.

•  Find your vested 401(k) balance
•  Check your next vesting milestone
•  Find your outstanding loan balance
•  Ask what happens to your loan after you leave
•  Save your plan and loan documents before you lose access to employee systems

And don’t feel pressured to make every decision about your old 401(k) immediately.

Leaving your job and deciding what to do with your old 401(k) are two separate decisions.

Know these three things before you leave

Your 401(k) balance on the screen may not tell the whole story…

Part of your employer contributions might not be vested yet. You might have a loan that needs attention.

Before your last day, know:

• What’s mine?
• What do I still owe?
• What deadline applies?

You don’t need to become a 401(k) expert. You just don’t want your first reminder about an old 401(k) loan to arrive at tax time.

Frequently Asked Questions

Do I lose my 401(k) when I quit?

No. Your own contributions are always 100% vested. You may give up employer contributions that haven’t vested yet.

Do I lose my employer 401(k) match when I quit?

You keep the portion that’s vested. Unvested employer contributions may be forfeited according to your plan’s rules.

Does my 401(k) loan become due when I quit?

Not always. Your plan determines what happens after you leave. Ask your plan provider whether you can continue payments or whether the remaining balance must be repaid.

Should I wait until I’m vested before quitting?

Check your next vesting date and how much money is at stake. Being a few days or weeks away from earning more of your employer contributions could be worth knowing before you choose your last day.
