Everyone Rushed to Convert Before the Tax Cliff. Congress Just Removed It.

For most of the last decade, one warning ran through every retirement column: today's tax rates are on sale, and the sale ends soon. The rate cuts passed in 2017 were written to expire at the end of 2025, which meant that in 2026 the brackets would snap back up — a 22% bracket becoming 25%, a 24% bracket becoming 28%. So the advice was to hurry. Convert your traditional IRA to a Roth now, pay tax at the low rate while you still can, and beat the deadline.

The deadline is gone. The 2025 tax law made the current brackets permanent, and the IRS has confirmed the 2026 schedule keeps the same seven rates, topping out at 37%. There is no cliff to beat anymore. For anyone who has been feeling the pressure to convert before some looming reset, that pressure has quietly evaporated — and it changes not whether a Roth conversion makes sense, but when.

Why everyone was in such a hurry

A Roth conversion moves money from a traditional (pre-tax) IRA or 401(k) into a Roth account. You pay ordinary income tax on the amount you move this year, and in exchange that money — and every dollar it earns from then on — comes out completely tax-free in retirement. The entire question is what rate you pay on the way in.

That is why the expiring 2017 cuts created such urgency. If your conversion was going to be taxed at 24% in 2025 but 28% in 2026, converting before the deadline was a straightforward win. Millions of dollars moved into Roth accounts in the final months of 2025 for exactly that reason. Now that the rates are permanent, the arbitrage of "convert before the rate resets" no longer exists. The rate you would pay next year is the same rate you would pay this year, and the year after that.

It is tempting to read that as bad news, as if an opportunity closed. It is the opposite. What closed was the false deadline, the one that pushed people into rushed, calendar-driven conversions whether or not the timing suited their own income. The conversion tool is still fully intact. You just get to use it on your schedule instead of the tax code's.

The new question: which bracket are you filling?

With no cliff to beat, a conversion becomes a pure bracket decision. Because the converted amount is added to your ordinary income for the year, the smart move is to convert only as much as fits inside your current bracket before it spills into the next one up. Tax brackets are marginal, so filling the one you are already in costs you that rate — and not a cent more — on the converted dollars.

Here is what that headroom looks like for a married couple filing jointly under the 2026 brackets. Find the row closest to your taxable income, and the last column is roughly how much you could convert this year without climbing into a higher rate.

This is where a cool head beats a calendar. The old deadline rewarded urgency; the new reality rewards the opposite — a plan. The right instinct now is to stick to a strategy and make the rational call rather than an emotional one: decide the rate you are willing to pay, convert exactly enough to fill it, and stop. A conversion driven by a bracket target is one you can repeat calmly year after year. A conversion driven by fear of a deadline is one you might regret when the tax bill lands.

Why paying the tax early is the whole point

Take the middle row. A couple earning $150,000 in taxable income sits in the 22% bracket with about $61,400 of room before the 24% bracket begins. Convert that $61,400 and the tax bill is roughly $13,508 — 22% of the amount moved. That is the entire cost, paid once.

That is the case for converting even when your rate today equals your rate in retirement. Taxing the seed is always cheaper than taxing the harvest, because the seed is smaller. See what any conversion amount becomes over your own time horizon in the Roth IRA calculator, and you will notice the tax-free balance pulling steadily away from the taxable one the longer you leave it alone.

One rule makes or breaks this: pay the conversion tax from money outside the retirement account — ordinary savings — not by having it withheld from the amount you convert. Withholding shrinks the seed you are trying to plant, and if you are under 59½, the withheld portion can count as an early withdrawal and get penalized. The couple above should send that $13,508 from a checking or brokerage account, so the full $61,400 lands in the Roth and starts compounding tax-free.

When the calm math says go — and when it says wait

Permanent rates do not mean every year is equally good to convert. The best years are the low-income ones, when your bracket temporarily drops and the same conversion costs less: an early-retirement gap before Social Security and required distributions begin, a sabbatical, a business down year, or a stretch of part-time work. Filling a 12% bracket in a quiet year is a far better deal than filling a 24% bracket at your peak earnings.

Two cautions belong on the checklist. First, the pro-rata rule: if you hold other pre-tax IRA money, the IRS treats all of it as one pool, so a conversion is taxed proportionally across pre-tax and after-tax dollars — you cannot cherry-pick only the untaxed portion. Second, each conversion starts its own five-year clock before the converted amount can be withdrawn penalty-free, which matters if you are close to needing the money. Neither is a reason to avoid converting; both are reasons to plan the size and timing rather than improvise. To watch how those tax-free dollars accumulate against a taxable alternative over the years, the Compound Interest calculator makes the gap concrete.

The deadline is gone. The strategy isn't.

Losing the tax cliff took away the one thing that never belonged in a good conversion decision: panic. What is left is the part that always mattered — your bracket, your time horizon, and the plain arithmetic of paying a known rate now to erase an unknown one later. That decision does not expire at year-end. It waits for the year that suits you.

So skip the scramble. Look at where your income lands this year, measure the room to the next bracket, and decide whether filling it at today's permanent rate is a trade you want. Run your own number before you move a dollar, convert deliberately, and pay the tax from the side. The rush is over. The opportunity, on your own terms, is not.
