What to Do With Your Finances When You Change Jobs

Changing jobs is one of the most financially consequential events that happens regularly in your 20s and 30s. You're making decisions quickly, often while dealing with the stress of a transition, and some of the mistakes people make in this window are hard to undo.

Here's the checklist, in the order it tends to matter.

Before You Leave: Things to Handle at Your Current Job

Understand Your Vesting Schedule

Many employers vest their 401(k) match over a period of years, typically three to six years on a graded schedule. If you're 80% vested and leave before hitting 100%, you forfeit that unvested 20% of employer contributions. It's worth knowing exactly where you stand before you give notice. Sometimes waiting a few extra weeks or months is worth real money.

Request your vesting schedule from HR if you don't have it. This is a normal question to ask.

Collect Your Documents

Before your last day, make sure you have your most recent 401(k) statements, your plan administrator contact information, your Summary Plan Description (which outlines your plan's rules), and any information about deferred compensation or stock awards. Once you're gone, it becomes harder to get these quickly.

The Health Insurance Gap: Handle This First

Coverage at your old job typically ends on your last day or the last day of the month you leave, depending on your employer. Coverage at your new job might not start for 30 or 60 days. That gap is real and can be expensive if something happens during it.

Your options are:

COBRA: Extends your current coverage, but you pay the full premium including what your employer was covering. It's often expensive, $500 to $700 per month or more, but it's continuous and familiar. You have 60 days from coverage loss to elect COBRA, and it can be retroactive if you elect it after an unexpected medical event.
Marketplace plan: A job loss is a qualifying life event that triggers a special enrollment period. You can buy a plan through healthcare.gov. Depending on your income during the gap months, you may qualify for subsidies.
Spouse or partner's plan: A job loss also triggers a special enrollment period for your spouse's employer plan. This is often the cleanest option if it's available.

The key: don't wait and assume the new job's coverage will start immediately. Confirm the start date in writing. If there's a gap, you need a plan before your last day at the old job.

What to Do With Your Old 401(k)

This is where most people either do nothing (leaving money in an old account they forget about) or do the one thing they shouldn't: cash it out.

Do not cash out your 401(k). If you're under 59 and a half, you'll pay ordinary income tax on the full amount plus a 10% early withdrawal penalty. On a $30,000 balance, that could cost you $8,000 to $12,000 or more depending on your bracket. The money is gone and the compounding it would have done is gone with it.

Your options for the old 401(k):

Roll it into your new employer's 401(k): Clean consolidation. Keeps everything in one place. Only works if the new plan accepts incoming rollovers (most do) and offers decent investment options.
Roll it into an IRA: More investment flexibility, usually lower fees, and you control it directly. A direct rollover from 401(k) to IRA is not a taxable event if done correctly. Use a direct rollover (check made out to the new account, not to you personally).
Leave it in the old plan: Fine as a temporary option, especially if the plan has strong investment options. But forgotten accounts are a real problem, and consolidating is usually better in the long run.

At the New Job: Get the Match, Read the Benefits

Maximize the Employer Match on Day One

Most employers require you to enroll in the 401(k) within a set period, often 30 to 90 days. Some have a waiting period before you're eligible. Find out both. If there's no waiting period and the match starts immediately, enroll during the first week.

Contribution rate matters: if your new employer matches 100% up to 4% of your salary, you need to contribute at least 4% to capture the full match. Contributing 2% means you're leaving half the match on the table. Make sure your contribution rate is set correctly from the start.

The 2026 401(k) employee contribution limit is $24,500. If you were contributing to your old plan earlier in the year, keep track of your year-to-date contributions so you don't over-contribute between the two plans.

Compare Benefits Carefully, Not Just Salary

Before you accepted the offer, you probably compared base salary. But the full picture includes health insurance premiums and plan quality, 401(k) match structure, HSA eligibility, paid time off, any equity compensation, and vesting schedules on the new match. These can add or subtract thousands of dollars per year in real compensation.

If you're comparing two offers or negotiating, the 401(k) match and health insurance costs are often more negotiable than people realize, or at least worth factoring into how you evaluate the offer.

A Note on Going Self-Employed or Contract

If you're moving from W-2 to self-employed or contract work, the financial checklist changes significantly. You're now responsible for both halves of FICA taxes (15.3% on self-employment income), quarterly estimated tax payments, and your own retirement account setup. A SEP-IRA or Solo 401(k) can allow significant tax-deferred contributions, sometimes well above the standard 401(k) limits depending on your income.

The health insurance situation also changes. You'll be buying your own plan, either through healthcare.gov or directly from an insurer. Self-employed individuals can often deduct 100% of health insurance premiums from their income, which partially offsets the cost.

Frequently Asked Questions

What happens to my 401(k) when I quit my job?

The money is yours and stays yours. You can leave it in the old plan temporarily, roll it to an IRA, or roll it to your new employer's 401(k). What you should not do is cash it out. Doing so triggers income taxes plus a 10% early withdrawal penalty if you're under 59 and a half, wiping out a significant portion of the balance.

How long do I have to roll over my 401(k) after leaving a job?

If your old employer sends you a check directly (an indirect rollover), you have 60 days to deposit it into a qualified account before it becomes taxable and subject to penalties. Your employer is also required to withhold 20% for taxes in that case. A direct rollover, where the money goes straight from the old plan to the new account without passing through your hands, avoids all of this. Always use a direct rollover.

Will I lose my 401(k) match if I leave before the vesting period ends?

Potentially, yes. Unvested employer contributions are forfeited when you leave. Your own contributions are always 100% yours. Check your vesting schedule before setting your last day, since being close to a vesting milestone might be worth waiting for.

What should I do about health insurance between jobs?

Your three main options are COBRA (extends current coverage at full cost), a marketplace plan through healthcare.gov (job loss is a qualifying event), or joining a spouse or partner's employer plan if available. Confirm your coverage end date at the old job and your start date at the new one before deciding. COBRA can be elected retroactively within 60 days, so if the gap is short and you're healthy, some people wait to see if they need to elect it.

Can I contribute to two 401(k) plans in the same year if I change jobs?

Yes, but the contribution limit applies to you as an individual, not to each plan separately. In 2026, the limit is $24,500 total across all 401(k) plans. If you contributed $10,000 to your old employer's plan, you can contribute up to $14,500 to your new one. Track your year-to-date contributions so you don't accidentally exceed the limit, which creates a tax problem.
