Why the Next 3 Years Could Be Critical for Roth Conversions — and Why the 2026 Window Is Closing

If you have a significant amount of money in a traditional IRA or 401(k), the next three years could be an important window for Roth conversion planning.

And if you are considering a Roth conversion in 2026, time is already running short.

Recent tax legislation extended and made permanent many of the individual tax provisions originally enacted under the Tax Cuts and Jobs Act. That gives retirees and pre-retirees something extremely valuable when planning Roth conversions: greater clarity about today’s federal income tax rates.

But “permanent” does not mean tax rates can never change.

Congress can change the tax code again. Your income can change. Required minimum distributions can increase your taxable income later in retirement. Social Security, investment income, Medicare premiums, and the death of a spouse can all change the tax picture.

That is why 2026, 2027, and 2028 could represent an important planning opportunity.

Why Could the Next Three Years Be Important for Roth Conversions?

A Roth conversion allows you to move money from a tax-deferred retirement account, such as a traditional IRA, into a Roth IRA.

You generally pay income taxes on the taxable amount converted today. In exchange, qualified Roth IRA withdrawals in the future can be tax-free.

The basic question is:

Would you rather pay taxes on some of your retirement money today, or potentially pay taxes on that money later?

The answer depends heavily on your tax rate.

If you believe you are paying a relatively favorable tax rate today compared with the rate you could face later in retirement, converting some traditional IRA assets to a Roth IRA may be worth analyzing.

The current tax environment gives us a clearer starting point for doing that analysis.

What we do not know is what Congress will do five, 10, or 20 years from now.

Instead of trying to predict future tax laws, you can use the next several years to systematically evaluate whether moving portions of your tax-deferred savings into Roth accounts makes sense.

Why Is 2026 Particularly Important?

Because you only get one 2026.

A common mistake with Roth conversions is assuming you can simply make up for a missed conversion next year.

You cannot go back and use unused space in a prior year's tax brackets.

Suppose your income leaves room to recognize additional taxable income in 2026 at a tax rate you find attractive. A carefully calculated Roth conversion could potentially use some of that available tax-bracket capacity.

If you wait until 2027, the 2026 opportunity is gone.

Your situation could also be different next year.

Your portfolio could increase in value. You could begin receiving Social Security. You might have additional investment income. You could sell a property or business. Required minimum distributions could begin. Or another financial event could push your taxable income higher.

Roth conversion opportunities are annual opportunities. Once December 31 passes, that year's window closes.

Why Waiting Until December Can Be a Mistake

Technically, a Roth conversion can be completed late in the year.

Strategically, waiting until the last minute may not be ideal.

A Roth conversion should not begin with the question, “How much should I convert?”

It should begin with a broader tax analysis.

You may need to estimate your 2026 taxable income, review your expected deductions, determine your current marginal tax bracket, analyze how a conversion could affect other parts of your tax situation, and decide where the money to pay the resulting taxes will come from.

That takes planning.

With 2026 approaching its final months, now is an appropriate time to begin that analysis rather than waiting until the final weeks of December.

Who Should Consider a Roth Conversion in 2026?

Roth conversions aren't appropriate for everyone. However, they may deserve particular attention if you:

• Have a large traditional IRA, 401(k), or other tax-deferred retirement account

• Are retired but have not yet started required minimum distributions

• Recently retired and have temporarily lower taxable income

• Expect your future income tax rate to be higher

• Want to reduce the size of future required minimum distributions

• Have substantial assets you expect to leave to your children

• Have enough non-retirement assets available to pay the conversion tax

• Want greater flexibility over where retirement income comes from

For some retirees, the years between retirement and required minimum distributions can be especially important.

Your wages may have stopped, but large mandatory retirement-account distributions may not have started yet.

That gap can create a valuable Roth conversion window.

Why Not Convert Your Entire IRA at Once?

Because a Roth conversion creates taxable income.

Converting too much in one year could push additional income into higher tax brackets and potentially create other unintended tax consequences.

That is why a multi-year Roth conversion strategy can be more useful than simply asking whether you should “do a Roth conversion.”

Instead, you might ask:

How much should I convert in 2026, 2027, and 2028 based on my overall retirement tax strategy?

For example, instead of converting a very large IRA balance all at once, you might evaluate a series of partial conversions over several tax years.

The appropriate amount could be completely different for two retirees with identical IRA balances because their income, deductions, age, Social Security benefits, investment income, estate plans, and other circumstances may differ.

Are Roth Conversions Still Worth Considering After the Trump Tax Cuts Were Extended?

Yes.

In fact, the extension of today's tax structure may make proactive Roth conversion planning more compelling because you have greater visibility into the current tax environment.

But the reason to consider a Roth conversion should not simply be, “Taxes might go up.”

Nobody knows exactly what future tax rates will be.

The better question is whether paying tax on a portion of your IRA today could improve your long-term financial plan.

That requires running the numbers.

What Happens If You Do Nothing?

Doing nothing is still a decision.

If you leave all of your money in tax-deferred retirement accounts, those accounts may continue growing. Eventually, required minimum distributions may force money out of those accounts and onto your tax return.

For someone with a large IRA, that could create considerably more taxable income later in retirement.

There is also the possibility of eventually filing taxes as a single taxpayer after the death of a spouse. A surviving spouse may have many of the same assets and similar retirement income but face a different tax situation.

A Roth conversion strategy can potentially help diversify your retirement savings among accounts with different tax characteristics.

Should I Do a Roth Conversion Before the End of 2026?

Maybe — but the decision should be based on an analysis rather than a rule of thumb.

The real question isn't simply whether Roth conversions are good or bad.

It is:

Does a Roth conversion make sense for you in 2026, and if so, how much should you convert?

That is exactly what a Roth conversion analysis is designed to determine.
