Teachers, police officers, firefighters, and other public employees often ask me whether their 457(b) can be converted to a Roth. The short answer is yes, if it’s a governmental 457(b), and no, if it’s a 457(b) from a tax-exempt employer like a hospital or a private university. Even when a conversion is allowed, it isn’t always the smart move, because a 457(b) has a withdrawal advantage you give up the moment the money lands in a Roth IRA. Here’s how a 457(b) Roth conversion works, what it costs, and how to decide.

Governmental vs. Non-Governmental 457(b): Why the Type Decides Everything

There are two very different plans that share the 457(b) name. Governmental 457(b) plans are offered by state and local governments, so they cover public school teachers, municipal workers, police, and firefighters. Non-governmental 457(b) plans are offered by tax-exempt organizations, usually only to executives and highly paid staff at places like hospitals, charities, and private universities.

The IRS comparison of the two plan types shows why only one of them can be converted:

The non-governmental version is a different animal. According to the IRS, those plans must remain unfunded, and the assets stay available to the employer’s general creditors if the organization runs into trouble. Since there’s nothing that can be rolled into an IRA, there’s no path to a Roth conversion. If you’re not sure which type you have, your plan’s summary plan description or HR department can tell you in a minute.

Two Ways to Do a 457(b) Roth Conversion

If you have a governmental 457(b), the IRS rollover chart allows the money to move into a Roth in two ways. In both cases, the chart notes you must include the converted amount in income.

In-Plan Roth Rollover

The IRS confirms that governmental 457(b) plans may offer designated Roth contributions and in-plan rollovers to a designated Roth account. With an in-plan rollover, you move some or all of your pre-tax balance into the plan’s Roth account without leaving the plan. The big advantage is that you may not need to leave your job, since many plans allow in-plan conversions while you’re still working. The catch is that it’s entirely up to your employer. If the plan document doesn’t include the feature, you can’t use it, and you’re still limited to the plan’s investment menu.

Rollover to a Roth IRA

The second route is a rollover from the 457(b) into a Roth IRA. This requires a distributable event, which usually means you’ve left the job. Some governmental plans also allow in-service distributions once you reach age 59½, so check your plan’s terms if you’re still working. Ask for a direct rollover, trustee to trustee. If the plan pays the money to you first, it generally has to withhold 20% for taxes, and you’d have to replace that 20% out of pocket within 60 days to convert the full amount.

What a 457(b) Roth Conversion Really Costs

The Tax Bill

Every pre-tax dollar you convert is added to your taxable income for that year. Convert $100,000 while you’re in the 22% federal bracket and you can expect roughly $22,000 in federal tax, plus state income tax in most states, and a large conversion can push part of the income into a higher bracket. The money you get in return is tax-free growth and, once you meet the Roth rules, tax-free withdrawals. Pay the tax from savings outside the plan if you can. Using part of the 457(b) to cover the bill means less money ends up growing in the Roth.

The 457(b) Advantage You Give Up

This point gets overlooked, and it matters a great deal for public employees who retire early. According to the IRS, distributions from a governmental 457(b) are not subject to the 10% additional tax on early distributions, except for amounts that were rolled in from another type of plan or IRA. A firefighter who retires at 52 can draw from a 457(b) the next day with no penalty.

A Roth IRA doesn’t work that way. If you’re under 59½, each conversion starts its own five-year clock, and withdrawing converted dollars before that clock runs out can trigger the 10% additional tax. Earnings in a Roth IRA withdrawn before 59½ generally face income tax and the 10% as well, as IRS Publication 590-B explains. So if you plan to live on this money before 59½, moving all of it into a Roth IRA can take away flexibility you already had.

When Converting Makes Sense, and When It Doesn’t

Converting tends to make sense when:

• You’re in an unusually low-income year, such as the gap between retiring from public service and starting Social Security or a second career.
• You won’t need the converted money for many years, ideally until after 59½.
• You can pay the tax from savings outside the plan.
• You expect your tax rate to be the same or higher later, or you want to leave tax-free money to your heirs.

It may not make sense when:

• You plan to retire before 59½ and live on this money, since the 457(b) gives you penalty-free access the Roth IRA won’t.
• The conversion would push you into a much higher bracket this year.
• You’d have to use the 457(b) itself to pay the tax.

You also don’t have to convert everything at once. A partial conversion each year, sized to fill up your current tax bracket, spreads the tax bill out and leaves some 457(b) money in place for early-retirement income. Worth noting for current employees: the 457(b) is also subject to the SECURE 2.0 rule that requires higher earners to make catch-up contributions as Roth starting in 2026, so some of your new money may be going in as Roth anyway.

Taking Control With a Self-Directed Roth IRA

If you do roll your 457(b) into a Roth IRA, the account doesn’t have to sit in the same mutual funds. I started IRA Financial in 2010 after discovering how much freedom the tax code gives retirement investors that most custodians never mention. A Self-Directed Roth IRA lets you invest converted dollars in real estate, private businesses, precious metals, or crypto, and all of that growth can come out tax-free once you meet the Roth rules. Our Self-Directed IRA costs a flat $495 a year with no fees tied to your account value. I explain how this works in more depth in Real Estate Investing with a Self-Directed IRA.

Final Thoughts

A governmental 457(b) can absolutely be converted to a Roth, and for the right person it’s one of the best long-term tax moves available. But the 457(b) already has a feature most retirement accounts don’t, penalty-free access at any age once you leave your job, and a conversion trades some of that away. Know which type of plan you have, run the numbers on the tax bill, and think hard about when you’ll actually need the money. If you’d like to understand what happens once the money is in a Roth, I cover the withdrawal rules in Roth IRA Distribution Rules and the mechanics of moving plan money in How to Complete a Self-Directed IRA Rollover. The decision is yours to make, and it’s worth making deliberately.
