The Roth conversion deadline they're selling you was repealed

It is the most repeated retirement pitch on the internet right now: "Convert your IRA to a Roth — now, aggressively, before rates go up and the window closes." Here is the honest check. The window that pitch is built on was repealed. In July 2025 the One Big Beautiful Bill Act made the 2017 tax brackets permanent — the IRS says so in its own words — so the sunset everyone is telling you to beat is gone. Nobody has to rush. But there is a real deadline in your tax code, and almost nobody is naming it: a brand-new $6,000-per-person deduction for age 65+ that exists only for tax years 2025 through 2028. The trap is that a Roth conversion is income — and income is exactly what switches that deduction off. Don't ask when the window closes. Ask which window you're standing in. Every figure below traces to the IRS sources at the end.

One deadline vs. three windows — why careful people fall for this

The pitch fools smart people because most of it used to be true. "Convert while rates are low, before the sunset" was correct advice — for about seven years. It stopped being correct in July 2025, and a lot of the internet hasn't re-read the law. So this isn't a story about anybody lying to you. It's a story about advice going stale. The fix is a simple model: picture three windows. Window one is the one they're selling you — rates about to jump, so convert before they do. Window two is the one that's actually open — a deduction that exists for four tax years and then vanishes. Window three is the one nobody mentions — the one a conversion shuts behind you, because the money you convert counts as income, and income is what takes window two away. The pitch only ever looks at window one. Hold onto the whole line for the next ten minutes: don't ask when the window closes — ask which window you're standing in.

Window one — the sunset that was repealed

Window one is the entire foundation of the pitch, and it takes ninety seconds to knock down. The 2017 tax law lowered the brackets but was written with an expiration date — everything was set to revert after 2025. That expiration is the engine behind every "convert now" countdown. Then in July 2025 the One Big Beautiful Bill Act passed and made those brackets permanent. Not extended — permanent. The IRS says it plainly: those current income-tax brackets "were due to expire at the end of 2025, but the One Big Beautiful Bill Act kept those brackets now going forward permanent." So the 22% bracket you're in today is the 22% bracket next year and the year after, unless Congress passes a brand-new law. Could a future Congress raise rates? Of course — Congress can do anything. But "Congress might someday" is a possibility, not a deadline. The urgency was the fictional part.

Here is the 2026 map that "permanent" bought you. For a married couple filing jointly, the 12% bracket runs to $100,800 of taxable income and 22% runs from there to $211,400. For a single filer, 12% runs to $50,400 and 22% to $105,700. The 2026 standard deduction is $16,100 single and $32,200 for a couple. Those numbers aren't moving on a schedule. Don't memorize them — memorize the windows.

Window two — the $6,000 window that's actually open

This is the one that should have been the headline. That same July 2025 law created something brand new: an extra deduction just for people 65 and older — $6,000 per person, or $12,000 for a married couple where both spouses are 65+. And here's what makes it a real deadline instead of a fake one: the IRS spells out the years. It's for tax years beginning after December 31, 2024 and before January 1, 2029 — in plain English, 2025, 2026, 2027, and 2028. Four tax years, then gone unless Congress renews it. That is a dated, narrow, expiring window — the exact thing the Roth pitch pretends to warn you about, except this one is actually real and nobody's selling it.

Two facts keep people from claiming it, and both are avoidable. First, you do not have to itemize — the IRS says the deduction is available for both itemizing and non-itemizing taxpayers, so it sits on top of your standard deduction whichever way you file. Second, if you're married you must file jointly — file separately and you get nothing, not a reduced amount, nothing. You also need a valid Social Security Number, and the age test on the 2025 form is being born before January 2, 1961. It's claimed on a form called Schedule 1-A, Part V. That's your receipt — pull it up.

Window three — the one your conversion shuts

Here's where a kitchen-table conversion decision goes wrong. That $6,000 doesn't just sit there safely — it phases out as your income rises. The IRS puts the line at $75,000 of modified adjusted gross income if you're single, $150,000 if you're married filing jointly. Above that line, the deduction starts shrinking. And "modified adjusted gross income" sounds like something you need a professional to decode — you don't. Read the form: for almost everyone, that number is just your AGI, the same figure already on line 11 of your last 1040. The only add-backs are foreign or U.S.-territory income; if that's you, you already know it. For everyone else, MAGI = AGI, full stop.

Now watch what that means. A Roth conversion is taxable ordinary income. It lands in your AGI. So every dollar you convert raises the exact number that's taking your deduction away — dollar for dollar. It's not a side effect; it's the same number doing both jobs. That's window three swinging shut: the money you convert to "beat the window" is what closes the window that was actually worth something.

It's a slope, not a cliff

Before any math, kill one thing you'll hear in fear-driven retirement content: this is not a cliff. Going one dollar over $75,000 does not cost you $6,000. The deduction bleeds out gradually, at a rate printed right on the form. Schedule 1-A, Part V, line 34, in black and white: "Multiply line 33 by 6% (0.06)." Six percent of however far you are over the line — that's the whole formula. So if you're $3,000 over, you lose $180 of deduction. Not $6,000. A hundred and eighty dollars. Anybody who tells you one dollar wipes it out is selling fear and hasn't opened the form.

The number nobody says out loud: couples lose 12 cents on the dollar

Here's the finding that isn't in any pitch, and it's for married couples. Go look at how the form actually adds it up. Line 35 works out one person's reduced deduction. Then line 36a gives that amount to you, and line 36b gives that same amount to your spouse. Read it again: both of you are reduced by 6% of the same excess income, at the same time. So for a married couple where you're both 65+, the real rate isn't 6% — it's 12%. Twelve cents of deduction gone for every dollar of income above $150,000. In practical terms, every extra $1,000 of Roth conversion above $150,000 MAGI costs a couple $120 of deduction — before you pay a cent of tax on the conversion itself. If you're single, it's $60 per $1,000 above $75,000. And that tells you where each ends: the deduction hits zero at $175,000 MAGI for a single filer and $250,000 for a couple. Above those lines, windows two and three don't apply to you at all.

Ray & Diane convert $80,000 "for the taxes"

Ray and Diane are both 66, both retired, running about $140,000 a year between a pension, Social Security, and withdrawals. Ray watched a video last month — nice office, real credentials, most of it correct — and was told to convert $80,000 into a Roth this year, before rates go up. The transfer form is on the kitchen table. Here's the number that wasn't in that video. At $140,000 they're under the line, so today they get the full $12,000 deduction. Convert $80,000 and it lands in AGI, pushing their MAGI to $220,000 — $70,000 over the $150,000 line. Twelve percent of $70,000 is $8,400. Their $12,000 deduction drops to $3,600. So Ray would pay ordinary income tax on all $80,000 and hand back $8,400 of a deduction he was getting for free — 70% of it — from a decision made specifically to save on taxes.

So does Ray just not convert? No — he stops treating this like a deadline and starts treating it like a dial. His income is $140,000; his line is $150,000. That's $10,000 of room this year. Convert $10,000 instead of $80,000 and his MAGI lands exactly on the line — the deduction doesn't move a dollar. Then he does it again next year, and the year after. That's what window one being permanently open actually bought him: he no longer has to cram it into one December. In fact, since the deduction expires after 2028, so does the penalty for converting — so the honest plan is nearly the opposite of what he was told: convert small through 2028, up to his room, then convert freely from 2029, when there's nothing left to lose.

Ellen — has the room, wrongly doing nothing

Ellen is 67, on her own, living on about $60,000 a year. She watched the same videos as Ray and came to the opposite conclusion: she heard "conversions can blow up your deduction," got scared, and decided to do nothing. That's a mistake too, just pointed the other way. Ellen's line is $75,000 and she's at $60,000 — she has $15,000 of room between where she is and where the deduction even starts to shrink. That's $15,000 of Roth conversion she can do this year, at rates that are now permanent, without touching a penny of her $6,000. For Ellen, the honest answer isn't "don't convert." It's "convert up to your line, and stop." The convert-everything crowd is answering a question she didn't ask; the never-convert crowd would have her sit on free room. Neither one knows her number.

Gary — past the phase-out, none of it applies

Gary is 68, still consulting, running about $300,000 a year between the business and his portfolio. He heard "the deduction phases out" and started doing anxious arithmetic. Gary — stop. The deduction is fully gone at $175,000 single, $250,000 for a couple. He's at $300,000. It's already zero. You can't lose something you don't have, so nothing in windows two or three applies to him. His conversion question is the ordinary one — what bracket now, what bracket later, can he fill a cheaper bracket before required withdrawals start. That's a real question. It's just not this one, and the point of naming Gary is that the math has to be yours: same advice, same year, same law, three completely different right answers.

Your conversion also taxes your Social Security

There's one more reason it's windows, plural. A conversion doesn't only hit the deduction — it also changes how much of your Social Security gets taxed, because that formula runs on your income too, and a conversion raises it. One transaction, two hits. And here's the precise part worth checking: you might assume the big senior deduction helps with the Social Security side. It does not. Look at where each lands on the return. Your AGI is line 11; the Social Security math is already decided there. The senior deduction goes on line 13b — below AGI. It lowers your taxable income but does nothing to protect your Social Security from being taxed. That's not opinion; it's the order of the form.

What to check this week

Skip the "should I do a Roth conversion" debate — it's the wrong question, because the answer depends entirely on how much room sits between your income and your line. Pull your last 1040, find line 11, and set it against $75,000 or $150,000. If there's room, a conversion up to that line is essentially free of the phase-out — that's Ellen. If a big conversion would blow past the line, price the lost deduction first — that's Ray, who's better off slicing it across years now that the brackets are permanent. And if you're already above $175,000 (single) or $250,000 (couple), the deduction is moot and it's a plain bracket decision — that's Gary. Same rule, three answers, and the only way to know yours is to run the number.

The honest verdict

So what's the verdict on "convert now before the window closes"? It depends — and the window they named is the wrong one. The window they're selling was repealed in July 2025; the IRS says the brackets are permanent. The window that's actually open is four tax years long, worth $6,000 a person, and ends in 2028. And the cruel joke is that the loudest advice in this space — convert aggressively, convert now — is the fastest way to spend the window it never told you about. Not because conversions are a scam; they're a good tool, and Ellen should do one this year. But a conversion has a price that went up for people over 65 in July 2025, and the people selling you urgency are still quoting the old price. Don't ask when the window closes. Ask which window you're standing in. Check the rule. Not the slogan.
