The IRS does permit rollovers between these 401(k) and 403(b) plans, allowing you to consolidate retirement savings when appropriate. However, not all 403(b) plans accept rollovers from 401(k) accounts. This decision is up to the individual plan administrator. While both 401(k) and 403(b) accounts are tax-advantaged retirement plans, they serve different employer types. 401(k)s are typically offered by private companies, whereas 403(b)s are designed for employees of public schools, non-profit organizations and certain ministries.

How to Transfer Your 401(k) to a 403(b)

The simplest way to transfer your 401(k) to a 403(b) is through a direct rollover. This method moves your funds directly between plan administrators without you handling the money.

To make one, first need to contact your new employer’s HR department to confirm they accept direct rollovers. If they do, request the necessary forms from both your former and current plan administrators. This will help you avoid potential tax withholding and penalties.

Another option is an indirect rollover. This involves receiving a distribution check from your 401(k) administrator that you must deposit into your 403(b) within 60 days. There are significant drawbacks to this approach, though.

For one, your former plan administrator will typically withhold 20% for taxes. As such, you’ll need to make up this difference from personal funds when depositing into your 403(b) to avoid taxes and potential penalties on that portion.

Additionally, it’s important to complete your rollover within the IRS-mandated 60-day window to avoid taxes and early withdrawal penalties. Missing this deadline could result in your distribution being treated as taxable income, plus a 10% early withdrawal penalty if you’re under 59½. Plan administrators may take several weeks to process paperwork, so start the process as soon as possible.
