Should You Rollover Your 401(k) or Leave It? Pros and Cons to Know

by | Jul 23, 2025 | Estate Planning

One of the Most Overlooked Financial Decisions

When you leave a job, one big question often gets ignored: what should you do with your 401(k)? It’s easy to let it sit untouched, but that might not be the best move. Rolling it over—or not—can have long-term effects on your retirement plan, investment performance, and tax efficiency.

There’s no one-size-fits-all answer, but understanding the pros and cons of each option can help you make a confident, informed decision.

Option 1: Leave It Where It Is

If your old plan allows it and your balance is high enough (typically $5,000 or more), you may be able to leave your 401(k) with your former employer.

Pros:

  • No immediate action needed

  • Institutional investment options may have low fees

  • Your money stays invested and continues growing tax-deferred

Cons:

  • Limited investment control

  • Harder to track and manage as you change jobs

  • Former employer can make changes or close the plan

  • Inactivity may lead to missed performance adjustments

Leaving your 401(k) behind is easy in the short term—but it could lead to neglect in the long run.

Option 2: Rollover Into an IRA

This option gives you more control and can integrate better with your overall financial strategy.

Pros:

  • Wider selection of investment options

  • Potentially lower fees

  • Easier to consolidate with other retirement accounts

  • No taxes or penalties if done properly

Cons:

  • Slightly more complex to set up

  • Requires active investment decisions or guidance

Rolling into an IRA is often the preferred strategy for people who want greater flexibility, especially when working with a financial advisor.

Option 3: Rollover Into Your New Employer’s Plan

If your new employer offers a solid 401(k) plan and accepts rollovers, you can move your funds directly into it.

Pros:

  • Keeps all retirement assets in one place

  • Maintains tax-deferred growth

  • May offer automatic contributions and employer matching

Cons:

  • Investment options may be limited

  • New plan might have higher fees

  • Some employers don’t allow rollovers

This option works best if you want simplicity and your new plan offers strong features.

Option 4: Cash It Out (But Be Warned)

Technically, you can take the money and run—but it comes at a steep price.

Cons:

  • You’ll owe income taxes on the full amount

  • If you’re under age 59½, expect a 10% early withdrawal penalty

  • You lose the opportunity for continued tax-deferred growth

  • It could impact your long-term retirement goals

Unless you’re in an emergency with no other options, cashing out should be avoided.

Key Questions to Ask Before Deciding

  • How do the fees and investment options compare?

  • Do you want more control or simplicity?

  • Are you working with an advisor who can manage an IRA?

  • Do you want to consolidate accounts to make future planning easier?

Your rollover decision shouldn’t be made in isolation—it should fit into your broader financial picture.
