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." The window that pitch stands on was repealed. In July 2025 the One Big Beautiful Bill Act made the 2017 tax brackets permanent, in the IRS's own words, so the sunset everyone is telling you to beat no longer exists. Nobody has to rush. There is a real deadline in your tax code, though, and almost nobody names it: a new $6,000 per person deduction for age 65 and over that runs only for tax years 2025 through 2028. The trap sits right there. A Roth conversion is income, and income is 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, three windows
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 much of the internet hasn't re-read the law. Nobody is lying to you. The advice went stale. Picture three windows instead. Window one is the one they're selling: rates about to jump, so convert before they do. Window two is the one actually open, a deduction that runs for four tax years and then vanishes. Window three is the one nobody mentions, the one your 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.
Was the Roth conversion deadline repealed?
Window one holds up the whole pitch, and it takes ninety seconds to knock down. The 2017 tax law lowered the brackets and carried an expiration date: everything reverted 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 puts it plainly: those 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 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.
So here's the 2026 map that permanence 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. None of those numbers moves on a schedule. Don't memorize them. Memorize the windows. Source: IRS, 2026 inflation adjustments.
Window two: the $6,000 window that's actually open
This one should have been the headline. That same July 2025 law created an extra deduction for people 65 and older: $6,000 per person, or $12,000 for a married couple where both spouses are 65 or over. What makes it a real deadline rather than a fake one is that the IRS spells out the years. 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. Dated, narrow, expiring, exactly the thing the Roth pitch pretends to warn you about. This one is real, and nobody is selling it.
Two things keep people from claiming it, and you can avoid both. First, you don't have to itemize. The IRS says it's available to itemizing and non-itemizing taxpayers alike, so it sits on top of your standard deduction either way. 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. You claim it on Schedule 1-A, Part V. That's your receipt. Pull it up. Sources: IRS, the enhanced deduction for seniors; Schedule 1-A.
Window three: the one your conversion shuts
This is where a kitchen-table conversion decision goes wrong. That $6,000 doesn't 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 it the deduction shrinks. "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 your AGI, the same figure already sitting on line 11 of your last 1040. The only add-backs are foreign or US territory income, and if that's you, you know it. For everyone else, MAGI is AGI.
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 takes your deduction away, dollar for dollar. That isn't a side effect. It's one number doing both jobs. Window three swings shut: the money you convert to beat the window closes the window that was worth something. Source: IRS, the enhanced deduction for seniors (income phase-out).
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. One dollar over $75,000 doesn't cost you $6,000. The deduction bleeds out gradually at a rate printed 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 over the line you are. That's the whole formula. Go $3,000 over and you lose $180 of deduction. Not $6,000. A hundred and eighty dollars. Anyone who tells you a single dollar wipes it out is selling fear and hasn't opened the form. Source: IRS, Schedule 1-A, Part V (the deduction phases out at 6 cents on the dollar, it does not cliff).
Couples lose 12 cents on the dollar
This part isn't in any pitch, and it matters if you're married. Look at how the form adds it up. Line 35 works out one person's reduced deduction. Then line 36a gives that amount to you and line 36b gives the same amount to your spouse. Read it twice: 6% of the same excess income reduces both of you, at the same time. So for a couple where you're both 65 or over, the real rate is 12%, not 6%. 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. Single, it's $60 per $1,000 above $75,000. That also tells you where each one ends. The deduction reaches zero at $175,000 MAGI for a single filer and $250,000 for a couple. Above those lines, windows two and three don't touch you. Source: IRS, the enhanced deduction for seniors (phase-out ends at $175,000 single / $250,000 joint).
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. It told him to convert $80,000 into a Roth this year, before rates go up. The transfer form is sitting on the kitchen table. One number 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, which is $70,000 over the $150,000 line. Twelve percent of $70,000 is $8,400. Their $12,000 deduction drops to $3,600. 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 he made specifically to save on taxes.
So does Ray skip the conversion? No. He stops treating it as a deadline and starts treating it as a dial. His income is $140,000 and his line is $150,000, so he has $10,000 of room this year. Convert $10,000 instead of $80,000 and his MAGI lands exactly on the line, with the deduction untouched. Then he does it again next year, and the year after. That's what a permanently open window one actually bought him: no cramming it into one December. And since the deduction expires after 2028, so does the penalty for converting. The honest plan runs nearly opposite to what he was told. Convert small through 2028, up to his room, then convert freely from 2029, when nothing is left to lose. Source: IRS, the enhanced deduction for seniors (the deduction runs for tax years 2025 through 2028).
Ellen has the room and is doing nothing
Ellen is 67, on her own, living on about $60,000 a year. She watched the same videos as Ray and drew the opposite conclusion. She heard that conversions can blow up your deduction, got scared, and decided to do nothing. That's a mistake too, pointed the other way. Her line is $75,000 and she's at $60,000, so she has $15,000 of room between where she sits 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. Her answer isn't "don't convert." It's "convert up to your line, then 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 knows her number. Source: IRS, 2026 inflation adjustments (bracket and standard-deduction figures behind the room calculation).
Gary is past the phase-out and none of it applies
Gary is 68, still consulting, running about $300,000 a year between the business and his portfolio. He heard that the deduction phases out and started doing anxious arithmetic. Gary can stop. The deduction is fully gone at $175,000 single and $250,000 for a couple, and he's at $300,000. It's already zero. You can't lose what you don't have, so nothing in windows two or three reaches him. His conversion question is the ordinary one: what bracket now, what bracket later, and can he fill a cheaper bracket before required withdrawals start. That's a real question. It just isn't this one. Gary is here to show that the math has to be yours. Same advice, same year, same law, three completely different right answers. Source: IRS, the enhanced deduction for seniors.
Your conversion also taxes your Social Security
There's one more reason these are windows, plural. A conversion doesn't only hit the deduction. It 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 check this part carefully, because the instinct is wrong. You might assume the big senior deduction helps on the Social Security side. It doesn't. Look at where each one lands on the return. Your AGI is line 11, and the Social Security math is already settled there. The senior deduction goes on line 13b, below AGI. It lowers your taxable income and does nothing to protect your Social Security from being taxed. That's not an opinion. It's the order of the form.
The calm move: convert to your line, not to a deadline
Fifteen minutes at the kitchen table. One: find your AGI on Form 1040, line 11. For this deduction that is your MAGI, unless you have foreign or territory income. Two: compare it to your line, $75,000 single or $150,000 married filing jointly. Three: subtract. The difference is your conversion room this year. Four: going over? Price it first, at $60 per $1,000 single or $120 per $1,000 for a couple in lost deduction, on top of the tax. Five: read Schedule 1-A, Part V yourself. Line 34 is the 6%. Line 36b is the couples number. Decide with a number in hand rather than a slogan. Sources: IRS, Schedule 1-A, Part V; Pub. 915 (a conversion also raises the combined income that taxes your benefit). And don't let taxes alone drive the call. The conversion is still a good tool when the number works.
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, set it against $75,000 or $150,000. Room to spare? A conversion up to that line is essentially free of the phase-out. That's Ellen. Would a big conversion 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. Already above $175,000 single or $250,000 as a couple? The deduction is moot and this becomes a plain bracket decision. That's Gary. Same rule, three answers, and the only way to know yours is to run the number.

Get the free guide→Should you convert now, before the window closes?
So what's the verdict on converting now before the window closes? It depends, and the window they named is the wrong one. The one they're selling was repealed in July 2025, and the IRS says the brackets are permanent. The one actually open runs four tax years, is worth $6,000 a person, and ends in 2028. The cruel joke is that the loudest advice in this space, convert aggressively and convert now, is the fastest way to spend the window it never told you about. Conversions aren't a scam. They're a good tool, and Ellen should do one this year. But a conversion got more expensive 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.

Common questions
Was the Roth conversion deadline really repealed?
The deadline behind the pitch was. The whole "convert now before rates go up" argument rested on the 2017 tax brackets expiring at the end of 2025. In July 2025 the One Big Beautiful Bill Act made those brackets permanent. The IRS says it in its own words: the brackets were due to expire at the end of 2025, but the One Big Beautiful Bill Act kept them going forward permanent. A future Congress could still raise rates, but that is a possibility, not a scheduled deadline, so nobody has to rush a conversion to beat a sunset that no longer exists.
What is the $6,000 senior deduction?
It is a new deduction the July 2025 law created for people 65 and older: $6,000 per eligible person, or $12,000 for a married couple where both spouses are 65+. It exists only for tax years beginning after December 31, 2024 and before January 1, 2029, which in plain terms means 2025, 2026, 2027, and 2028. It is claimed on Schedule 1-A (Form 1040), Part V, is available whether you itemize or take the standard deduction, and requires a valid Social Security Number. Married couples must file jointly to claim it.
Does a Roth conversion reduce the senior deduction?
It can. The deduction phases out once your modified adjusted gross income passes $75,000 single or $150,000 married filing jointly, and for almost everyone that MAGI is simply your AGI from Form 1040 line 11. A Roth conversion is taxable ordinary income, so every dollar you convert lands in that same AGI and raises the number that shrinks the deduction, dollar for dollar. Converting a large amount in one year can therefore hand back much of the deduction the window is worth, on top of the tax on the conversion itself.
Is the senior-deduction phase-out a cliff or a slope?
A slope, not a cliff. Going one dollar over your threshold does not cost you $6,000. Schedule 1-A, Part V, line 34 says to multiply the amount over your limit by 6% (0.06). So $3,000 over the line costs $180 of deduction, not the whole thing. Anyone telling you a single dollar wipes out the deduction has not read line 34.
Why do married couples lose the deduction twice as fast?
Because the form reduces both spouses at once. On Schedule 1-A, Part V, line 36a gives the reduced deduction to you and line 36b gives the same reduced amount to your spouse, each already cut by 6% of the income over $150,000. Both halves shrink simultaneously, so the effective rate for a couple is 12 cents per dollar, not 6. Every extra $1,000 of income above $150,000 MAGI costs a couple $120 of deduction; the couple's deduction reaches zero at $250,000 MAGI. A single filer loses $60 per $1,000 above $75,000 and hits zero at $175,000.
Should I still do a Roth conversion?
Often yes. A conversion is a genuinely good tool, and the sunset being repealed just removes the urgency, not the reason. The point is to count first. Find your AGI on Form 1040 line 11, compare it to your line ($75,000 single / $150,000 joint), and the gap is how much you can convert this year before the deduction starts to bleed. Convert up to your room, spread it across years now that the brackets are permanent, and if you are already above the phase-out entirely it becomes an ordinary bracket decision.
