What Happens to Your 403(b) When You Retire: A Complete Guide

Retiring from a job where you have a 403(b) plan means making important decisions about that retirement account. Understanding what happens to your 403(b) when you retire is crucial for maximizing your long-term financial security. The good news is that you have meaningful control over how you handle this money, and several clear paths forward exist.

Understanding the Three Main Options for Your 403(b)

When you leave your job and enter retirement, you generally face three distinct choices for your 403(b):

1. Leave your money invested in the current plan if it allows
2. Transfer your funds into an IRA or Roth IRA for more control and flexibility
3. Move your assets to a standard brokerage account and manage them as taxable investments

Each path has different tax implications, ongoing management requirements, and long-term benefits. The right choice depends on your specific situation, the quality of your current plan’s investments, and your retirement income needs.

Getting to Know Your 403(b) Plan

A 403(b) is a tax-advantaged retirement account designed specifically for employees of public schools, 501©(3) charitable organizations, and certain faith-based institutions. Like a 401(k), it lets you contribute pre-tax earnings directly from your paycheck into a retirement portfolio, and you’ll receive a tax deduction for these contributions.

In 2026, you can contribute up to $23,500 annually to your 403(b), the same limit that applies to 401(k) plans. Your employer can also add matching contributions if they choose to do so. The funds in your account grow tax-deferred, meaning you don’t owe taxes on the growth until you withdraw the money.

How 403(b) Plans Differ from 401(k)s

While 403(b)s and 401(k)s share many similarities, two key differences matter when you’re planning your retirement. First, employers typically contribute less to 403(b) plans compared to 401(k) plans, partly because nonprofits and schools usually have tighter budgets. Second, 403(b) plans can only offer annuities and mutual funds as investment options, whereas 401(k) plans provide a much broader range of choices. In practice, this means many 403(b) portfolios are heavily weighted toward annuity contracts, which are often managed by insurance companies.

Special Considerations: Annuities and Required Minimum Distributions

Because 403(b) plans frequently feature annuity contracts, they interact with required minimum distributions (RMDs) in ways that differ from typical 401(k) plans. Once you turn 73, federal rules require you to begin taking minimum annual distributions from your pre-tax retirement accounts.

The math becomes more complex with annuities. If your annuity contract is already paying out income to you, it typically doesn’t count toward your portfolio’s total value for RMD calculation purposes. However, if you’re holding annuity contracts that haven’t yet begun making payments, they do count toward your RMD calculation, potentially requiring you to sell other assets to meet your distribution obligation. There’s also a special category called a qualified longevity annuity contract (QLAC) that, if you begin taking distributions before age 85, won’t be included in your RMD calculations at all.

Your Options Once You Retire

Option 1: Keep Your Money in Your Current 403(b)

The simplest approach might be to leave your account with your former employer’s plan. This can work particularly well with 403(b) plans because the annuity structure often provides predictable lifetime or long-term income streams with minimal ongoing management needs on your part.

Staying with your current plan makes sense if your 403(b) offers strong investment options, favorable administrative fees, or special terms for plan participants. However, you need to check whether your specific plan even allows former employees to maintain accounts after leaving. Some plans require you to move the money out.

There are also reasons to consider moving on. Keeping money with a former employer can feel complicated, and you may worry about future changes to the plan, fee structures, or how the plan is administered. By moving your assets, you gain independence and eliminate these ongoing uncertainties.

Option 2: Roll Your Money into an IRA

Transferring your 403(b) into an Individual Retirement Account (IRA) is one of the most popular choices for retiring workers with employer plans. The primary advantage is that you take control of your investments and your future.

Moving to a Traditional IRA: You can roll your pre-tax 403(b) funds directly into a traditional IRA with no immediate tax consequences. Your money simply moves from one tax-deferred account to another. However, you need to verify that all your 403(b) investments—especially any annuity contracts—can be transferred without penalties or restrictions that would force an unwanted sale.

Once in the traditional IRA, your money remains tax-deferred, and you’ll owe income taxes on withdrawals in retirement. You’ll also be subject to the same RMD rules as your original 403(b), beginning at age 73.

Converting to a Roth IRA: Another option is converting your 403(b) balance into a Roth IRA. This is a more aggressive but potentially rewarding strategy. You’ll owe income taxes on the full amount you convert in the year you make the conversion, but once the money is in the Roth, qualified withdrawals later are completely tax-free. Additionally, Roth IRAs aren’t subject to RMD requirements, giving you more flexibility in retirement.

One important rule: if you’re under 59½ years old, you must wait five years after a conversion before you can withdraw those converted funds without penalty. However, if you’re already at retirement age, this restriction becomes less relevant. The upfront tax bill can be substantial, but many retirees find the long-term tax savings make it worthwhile.

Option 3: Withdraw Everything to a Taxable Account

You can also take a “full distribution” by cashing out your entire 403(b) and moving the proceeds into a regular brokerage account with no special tax status. Most financial advisors view this as the least attractive option for most retirees.

Like converting to a Roth, you’ll owe income taxes on the full amount distributed in the year you take it out. After that, the tax treatment of any gains depends on what you invest in. For example, if you buy stocks, you’ll only owe capital gains taxes on future profits, losing the tax-deferred growth advantage you had in the 403(b). You lose the IRS’s RMD protections as well, meaning you manage the account entirely on your own.

This approach might make sense in rare situations—for instance, if your 403(b) contains particularly poor-quality investments or excessive fees, and you’re confident you can do better in a taxable account. Before choosing this path, speak with a financial advisor about your specific circumstances.

Planning Your 403(b) Transition

Taking time to evaluate your choices before you retire pays dividends. Consider where your 403(b) funds are currently invested, what options your plan allows, and what your broader retirement income picture looks like. A qualified financial advisor can help you model the tax implications of each choice and recommend the approach that aligns with your overall retirement strategy.

The decision about what happens to your 403(b) at retirement isn’t one-size-fits-all, but by understanding each option’s mechanics, costs, and benefits, you’ll be in a strong position to choose the path that works best for your retirement years.
