Roth is named after William Roth, the senator who created it

Roth stands for William Volcker Roth, a U.S. Senator from Delaware who sponsored the legislation that created the Roth IRA in 1997. The account type is named after him because he championed the bill through Congress. When you hear "Roth IRA" or "Roth 401(k)", you are using his name as shorthand for a specific tax structure he helped design.

The formal name of the law is the Taxpayer Relief Act of 1997. Roth was a Republican senator who served Delaware from 1971 to 2003. He did not invent the concept of tax-deferred retirement savings — that already existed — but he pushed for a new version that let people pay taxes upfront and then withdraw money tax-free later. That trade-off became the defining feature of accounts that now carry his name.

Key Takeaways

  • Roth is the last name of Senator William Volcker Roth from Delaware, who sponsored the 1997 law creating the Roth IRA.
  • The account is named after him because he championed the legislation through Congress, not because he invented retirement savings.
  • A Roth account lets you pay income tax on contributions now and withdraw earnings tax-free in retirement, the opposite of a traditional IRA.
  • The name has become a category: you can have a Roth IRA, Roth 401(k), Roth 403(b), or Roth TSP, all following the same tax-now-withdraw-free structure.

Why the distinction matters for your savings

The name "Roth" tells you exactly how the account is taxed, which is the most important thing to know about it. When you see "Roth" in front of any retirement account type, you know that contributions go in after tax and withdrawals come out tax-free. When you see "traditional" instead, it means the opposite: contributions may be tax-deductible now, but withdrawals are taxed as income later.

This distinction shapes your entire savings strategy. If you expect to be in a higher tax bracket in retirement, a Roth account saves you money because you lock in today's tax rate. If you expect to be in a lower bracket, a traditional account often makes more sense. The name itself does not tell you which choice is right for you, but it tells you which tax structure you are considering.

Other account types that use the Roth name

After the Roth IRA became popular, Congress created other account types using the same tax structure. A Roth 401(k) is offered by some employers and works like a Roth IRA but with higher contribution limits and different withdrawal rules. A Roth 403(b) is the nonprofit and public school version. A Roth TSP (Thrift Savings Plan) is available to federal employees and military members.

All of these accounts share the Roth name because they all use the same principle: you pay tax on the money going in, and you pay no tax on the money coming out. The name has become a category label, much like "401(k)" or "IRA" — it describes a tax treatment, not a specific institution or product.

How the Roth IRA changed retirement savings

Before 1997, most people saving for retirement used a traditional IRA or 401(k). These accounts let you deduct contributions from your taxable income, which lowered your tax bill that year. But when you withdrew the money in retirement, every dollar was taxed as ordinary income. For high earners or people who expected to earn more in retirement, this structure was not ideal.

The Roth IRA offered a different path. You could not deduct contributions, but you paid no tax on withdrawals. This appealed to younger workers, people in low tax brackets, and anyone who thought tax rates would rise. The law also included a feature that traditional IRAs did not: you could withdraw your contributions (not earnings) anytime without penalty, which made the account more flexible for emergencies.

Income limits and who can use a Roth account

Not everyone can open a Roth IRA. The law sets income limits that change each year based on inflation. If your income is above the limit for your filing status, you cannot open a new Roth IRA or add money to one you already have. The limits are higher for married couples filing jointly than for single filers.

Roth 401(k)s and Roth TSPs do not have income limits — you can open one regardless of how much you earn. This is one reason some high earners use a Roth 401(k) when they cannot use a Roth IRA. The income limits apply only to direct contributions; there are workarounds like the "backdoor Roth" strategy, but those involve more steps and tax rules.

Frequently Asked Questions

Is Roth a company or a bank?

No. Roth is a person — Senator William Volcker Roth — and the account type is named after him. You open a Roth IRA at a bank, brokerage, or investment company like Vanguard, Fidelity, or Schwab. The institution you choose is separate from the Roth structure itself.

Can I have both a Roth IRA and a traditional IRA?

Yes, you can own both at the same time. However, your total contributions to all IRAs combined cannot exceed the annual limit set by the IRS. If you contribute to both in the same year, the amounts add together toward that single limit.

What happens to a Roth account if I die?

Your beneficiaries inherit the account and can withdraw the money. They will owe income tax on any earnings they withdraw, but not on your original contributions. The rules for inherited Roth accounts changed in 2023, so check current rules if you are naming a beneficiary.

Can I convert a traditional IRA to a Roth?

Yes. This is called a Roth conversion. You move money from a traditional IRA to a Roth IRA and pay income tax on the amount converted that year. This strategy makes sense if you expect tax rates to rise or if you are in a low-income year, but it has tax consequences you should plan for.
