What Should You Do With an Old 401(k)? A Complete Rollover Guide

Americans change jobs an average of twelve times during their careers, which means most people accumulate retirement accounts at multiple employers. Left unattended, these scattered accounts can lead to higher fees, limited investment options, and a fragmented financial picture. Understanding your rollover options is essential to staying on track.

Your Four Options

• Roll over to a Traditional IRA — often the most flexible option with a wider range of investments and potentially lower fees
• Roll over to a new employer 401(k) — consolidates accounts and may offer access to institutional-class funds
• Leave it in the old plan — an option if the plan has strong investment choices and low fees, but you lose the ability to contribute
• Cash it out — generally the worst option due to income taxes plus a 10% early withdrawal penalty if under age 59 and a half

The Rollover Process

A direct rollover, where funds transfer from one custodian to another without you touching the money, is the cleanest approach. This avoids mandatory 20% withholding and the 60-day deadline that applies to indirect rollovers. Contact both the old plan administrator and the receiving institution to initiate the transfer. Most rollovers complete within one to three weeks.

When a Roth Conversion Makes Sense

Rolling a traditional 401(k) into a Roth IRA triggers a taxable event; you will owe income tax on the full converted amount. However, this can be a smart move in years when your income is lower than usual, such as between jobs or in early retirement. The converted funds then grow tax-free and can be withdrawn tax-free in retirement. The decision should be evaluated within the context of your current and projected future tax rates.

Special Considerations

If your old 401(k) holds company stock with significant unrealized appreciation, Net Unrealized Appreciation (NUA) rules may allow you to pay long-term capital gains rates instead of ordinary income rates on the growth. If you are between 55 and 59 and a half and separated from service, your employer 401(k) allows penalty-free withdrawals that an IRA does not. These details matter and are worth discussing with a financial advisor before making a move.
