Your 401k when you quit: four options, only one right for most

Your 401k doesn't disappear when you quit. But you'll make a decision that costs thousands, or saves thousands. Here's which.

Know what's actually yours

Your own contributions are yours immediately, forever. The employer match? Only if you're vested. Most people aren't.

Two vesting types: cliff and graded

Cliff vesting: Nothing until year 3, then 100%. Quit in year 2, lose everything.

Graded vesting: 20% per year. After 1 year you own 20%. Year 2 you own 40%. Year 5 you own 100%. Quit in year 3, you keep 60%, lose 40%.

Average: 3-6 years. Tech: 4 years (25% per year). Check your documents. Don't guess.

Four options. Pick one.

Option 1: Leave it at your old job

ERISA law: employer can't force you out if balance is over $5,000. Most plans allow you to leave it.

Good: Nothing to do. No taxes. No penalties. Investments stay put.

Bad: Can't add to it. Can't control changes. Employer fees may apply. If they go bankrupt, you're insured up to $250k (but it's messy).

Verdict: Fine if fees are low. You lose control.

Option 2: Roll into new job's 401k

If your new employer takes rollovers (most do), you can move it there.

Good: No taxes. No penalties. Stays invested. Consolidates accounts.

Bad: You need a new job first. New plan might have higher fees. Lose the old plan's investment options.

Verdict: Best if you're moving to another job immediately.

Option 3: Roll into a Traditional IRA (the right move)

Direct rollover to an IRA. The money goes straight from old plan to IRA custodian. You don't touch it.

Good: No taxes. No penalties. No 10% early withdrawal penalty. Better fees than employer plans. Unlimited investment options.

Bad: IRAs have a $7,000/year contribution limit (2024, if under 50). Stuck until 59.5 without a 10% penalty (exceptions exist but are rare).

Verdict: Best for most people taking time off before next job.

Option 4: Cash it out (don't)

You can withdraw it all as a check. Simple. Expensive.

$50,000 balance example:

• Federal income tax (22% bracket): $11,000
• 10% early withdrawal penalty: $5,000
• State income tax (~6%): $2,500
• Total gone: ~$18,500
• You take home: ~$31,500

You're losing 37% of the money. On $100k, you lose $37,000+.

When it makes sense: You're in actual crisis. Eviction. Medical emergency. Not "I want a sabbatical."

Verdict: Don't do this.

Roth 401k exception

Roth 401k contributions come out tax-free before 59.5. Earnings don't.

Example: You put in $50k, it's now $65k (with $15k gains).

• Pull out $50k: $0 tax, $0 penalty
• Pull out the $15k earnings: 10% penalty plus income tax

Useful if you have one. Most people don't.

The 60-day trap

If they send you a check instead of rolling it directly, you have 60 days to deposit it in an IRA. Miss the deadline by one day, you pay taxes plus 10% penalty on everything.

Don't let this happen. Request "direct rollover" by name. Don't take the check.

Don't use 401k as runway

This is the most common mistake. You quit, you need cash, you think "just $10k from my 401k."

That $10k becomes $6,500 after taxes and penalties. You've destroyed retirement savings to cover short-term cash.

Use separate runway money. Use emergency funds. Use side income. Use unemployment. Don't touch the 401k.

Decision tree

Moving to another job immediately?

• Yes → Roll to new employer's 401k
• No → Next question

Have runway savings separate from this?

• Yes → Roll to IRA, leave it alone
• No → Next question

In genuine financial hardship?

• Yes → Talk to a tax pro before cashing out
• No → Roll to IRA, leave it alone

Summary

Your 401k is retirement money, not runway money. Roll it to an IRA. Don't touch it. Fund your break from actual savings.

Check your vesting date before you quit. If you're one month from full vesting on a 3-year cliff, staying 4 weeks might be worth it. Don't stretch a bad job for a bad vesting schedule.

This is not financial advice. Tax law is complex. If you're cashing out, talk to a CPA first. One hour costs less than a $20k penalty surprise.
