At a Glance

• Think in terms of lifetime taxes, not this year’s refund.. A Roth IRA trades a small tax bill today for the chance to avoid bigger ones later. A traditional IRA defers the bill but doesn’t erase it, you’re just deciding when to pay.

• Control is the real benefit, not just tax savings. Having both Roth and traditional accounts gives you flexibility to manage your income in retirement. That control can help you stay in your chosen tax bracket, avoid Medicare surcharges, and keep more of your Social Security benefits.

• Use strategy, not luck, to pick your timing. You can shift money between account types through conversions, or use a backdoor Roth if you earn too much to contribute directly. Numerous people convert right away, but waiting for a low-income year or a move to a no-tax state can make it even smarter.

Deciding between a Roth and traditional IRA is a choice every investor makes at some point, from beginners investing their first dollar to those with millions already invested.

As an investor, your goal is to invest in a way that gives you the highest after-tax return on your money.

You can do that in one of two ways:

• Asset Allocation: The types of investments you choose , stocks, bonds, cash, mutual funds, and so on.
• Asset Location: The types of accounts you invest in , such as a traditional or Roth IRA, 401(k), Health Savings Account (HSA), or taxable brokerage account.

Choosing between a traditional and Roth IRA is a question of asset location.

Neither type of IRA is inherently better than the other. The best choice depends on your individual financial situation and tax outlook.

One common rule of thumb is that if your tax rate is higher now than it will be in retirement, a traditional IRA may make more sense. But to get the right answer, there’s more to consider.

And it’s worth taking the time to get it right , recent updates under the SECURE 2.0 Act and the IRS adjustments for 2025 and 2026 have changed contribution limits, catch-up rules, and required minimum distribution ages.

Choosing the right account today can have a sizable impact on your future retirement savings.
