How to Manage Your Investments When Changing Jobs
Last updated: March 2026
Changing jobs is a critical moment for your investment portfolio. You need to decide what to do with your old 401(k), evaluate new employer benefits, and handle any stock options or RSUs. The wrong rollover decision can cost you thousands in fees and taxes. This guide covers every financial move you should make during a job transition.

What to Do With Your Old 401(k)
When you leave an employer, you have four options for your 401(k): leave it in the old plan, roll it into your new employer's plan, roll it into an IRA, or cash it out. Cashing out triggers income taxes plus a 10 percent penalty if you are under 59 and a half, so that option is almost never the right choice.
For most people, rolling into an IRA at a low-cost brokerage like Fidelity, Schwab, or Vanguard is the best option. An IRA gives you access to thousands of low-cost ETFs instead of the limited fund menu in most 401(k) plans. The rollover process is straightforward: open a traditional IRA, request a direct rollover from your old plan, and the money transfers without triggering any taxes.
Evaluating Your New Employer Benefits
Before your first day, review your new employer's 401(k) plan details. Key things to evaluate: the employer match percentage and vesting schedule, the available fund options and their expense ratios, and whether a Roth 401(k) option is available. Some employers offer excellent low-cost index fund options, while others have expensive actively managed funds.
If your new plan has high-cost funds, contribute only enough to capture the full employer match, then direct additional savings into your IRA where you control the investment choices. A 50-percent employer match is an instant 50-percent return on your money, which outweighs even high fund expenses in the short term.
Handling Stock Options and RSUs
If your previous employer granted stock options or restricted stock units, you typically have 90 days after your last day to exercise vested stock options. Unvested equity is usually forfeited. Review your equity agreement carefully because the deadlines are strict and missing them means losing potentially valuable compensation.
If you exercise stock options, consider the tax implications before deciding how many shares to hold versus sell. Concentrated single-stock positions are risky. Most financial advisors recommend selling company stock that represents more than 10 percent of your net worth and reinvesting the proceeds into diversified ETFs. This is especially important when leaving a company because you no longer have insider knowledge of its future prospects.
Bridging the Income Gap
If you have any gap between jobs, your emergency fund becomes critical. Even a two-week gap between paychecks can strain your finances if you have not planned ahead. Do not sell investments to cover short-term expenses during a job transition. This is exactly what your emergency fund is for.
Also consider health insurance during the transition. COBRA coverage from your previous employer is available but expensive, often $600 to $1,800 per month for family coverage. A short-term health insurance plan or marketplace plan might be more affordable. Factor these costs into your transition budget so your investment contributions can resume immediately at your new job.
Optimizing Your Fresh Start
A new job is an excellent time to optimize your entire financial strategy. You often get a salary increase, which means you can increase your savings rate without feeling a pinch. Apply the rule of investing at least half of any raise. If your new salary is $10,000 more per year, direct at least $5,000 of that increase into additional investments.
Set up your new 401(k) contributions immediately during onboarding. Many people procrastinate and miss months of contributions and employer matching. Enroll on day one at your target contribution rate. Also update your investment beneficiaries, adjust your tax withholding on your W-4, and review whether your new compensation package changes your eligibility for Roth IRA contributions.

Action Steps
Document your old benefits before leaving
Screenshot or save details of your 401(k) balance, vesting schedule, stock options, and any other equity compensation before you lose access.
Initiate a direct IRA rollover
Contact your old 401(k) provider and request a direct rollover to your IRA. A direct rollover avoids the 20% mandatory withholding that comes with an indirect rollover.
Exercise vested stock options within the deadline
Check your equity agreement for the post-termination exercise window, usually 90 days. Decide which options to exercise based on current price versus strike price.
Enroll in your new 401(k) on day one
Do not wait. Set your contribution rate to at least capture the full employer match immediately. You can always adjust later.
Invest at least half your raise
If your new job came with a salary increase, commit to investing at least 50% of the after-tax difference before lifestyle inflation absorbs it.
Update all beneficiaries
Review and update beneficiary designations on your old rolled-over IRA, new 401(k), and any life insurance policies.
Frequently Asked Questions
How long do I have to roll over my 401(k)?
There is no legal deadline for a direct rollover, but it is best to complete it within 60 days to avoid complications. If you receive a check made out to you (indirect rollover), you must deposit it into an IRA within 60 days to avoid taxes and penalties.
Should I roll my 401(k) into a Roth IRA?
Rolling a traditional 401(k) into a Roth IRA triggers a taxable event because you are converting pre-tax money to after-tax. This can make sense if you are in a low tax bracket this year, such as during a gap between jobs, but the tax bill can be substantial on large balances.
What if my old 401(k) has good low-cost funds?
If your old plan offers institutional-class funds with very low expense ratios, it can make sense to leave the money there. Compare the expense ratios and fund options of your old plan, new plan, and an IRA before deciding.
Can I contribute to both my old and new 401(k) in the same year?
Yes, but the total employee contribution limit applies across all 401(k) plans combined. In 2025, that limit is $23,500. Employer matches do not count toward this limit.
