Hello friends. In July 2025, Congress passed the One Big Beautiful Bill Act, and it changed the tax rules for every person in America who has money in a 401k, a traditional IRA, or any other tax-deferred retirement account. Some of those changes save you money. Some of them cost you money, and most people over 60 do not know about either one.
The biggest news is what did not happen. The Tax Cuts and Jobs Act of 2017 was scheduled to expire at the end of 2025. That would have sent tax rates back to pre-2018 levels, increased your tax bracket on every dollar you withdraw from your retirement accounts, and raised the effective tax rate on your Social Security benefits. That sunset did not happen. The current seven tax rates, 10%, 12%, 22%, 24%, 32%, 35%, and 37%, have been made permanent.
But here is what most people missed. The bill also created a brand new deduction specifically for Americans age 65 and older. It changed the rules for 401k catch-up contributions for high earners. It increased contribution limits, and it shifted the standard deduction in ways that directly affect how much of your retirement income is taxed. If you are over 60 with money in a 401k, every one of these changes affects the tax bill on every withdrawal you make from this point forward.
Today, I am going to walk you through the four tax changes that matter most to retirees in 2026, show you exactly how they affect your withdrawals, and give you the strategies that can keep your retirement income in the lowest tax bracket possible. If you are over 60 and you have money in a 401k or an IRA, this is information you need before you make your next withdrawal.
Before we get into it, if you are not subscribed to this channel, please do that right now and turn on the bell. Tax laws change every year. The brackets move. The deduction amounts change. The rules for retirement accounts get updated. The people who are subscribed here find out about these changes in time to adjust their withdrawal strategy. The people who are not find out when they file their taxes and discover they owe more than they expected. Hit subscribe, turn on the bell, and let's get into it.
Change number one. The new senior deduction that most people over 65 do not know about. For tax years 2025 through 2028, the One Big Beautiful Bill Act created a separate deduction specifically for taxpayers age 65 and older. This is not the same as the additional standard deduction that has existed for years. This is a new additional deduction on top of the existing standard deduction and on top of the additional standard deduction for being over 65. The new senior deduction is worth up to $4,000 per qualifying individual. If you are married filing jointly and both spouses are 65 or older, the deduction is up to $8,000.
Let me show you what this means in real numbers for 2026. A married couple, both over 65, filing jointly, their standard deduction is approximately $32,300. Their additional standard deduction for being over 65 is $1,600 per person or $3,200 for the couple. And now their new senior deduction is up to $4,000 per person or $8,000 for the couple. Total deductions before a single dollar of tax: $32,300 plus $3,200 plus $8,000 equals $43,500. That means a married couple, both over 65, can receive up to $43,500 in income from their retirement accounts, Social Security, and pensions before they owe a single penny in federal income tax. That is a significant increase from recent years, and most people do not know about it.
For a single filer over 65, the numbers are approximately $16,150 standard deduction plus $1,600 additional standard deduction plus $4,000 new senior deduction for a total of $21,750 in deductions.
Now, there is an income phase-out on the new senior deduction. It begins to phase out at higher income levels, which means if your adjusted gross income is above a certain threshold, the deduction starts shrinking. If your income is above $150,000 as a single filer or $300,000 as a married couple filing jointly, the deduction may be reduced or eliminated. But, for the vast majority of retirees whose income is below those thresholds, the full deduction applies.
Here is why this matters for your 401k withdrawals. Every dollar you withdraw from a traditional 401k or traditional IRA is taxed as ordinary income. The more you withdraw, the higher your taxable income, and the higher your marginal tax rate. But, these increased deductions mean you can withdraw more money before you enter the taxable income range at all. The deductions create a larger tax-free zone at the bottom of your income. If you are over 65 and you have been holding off on taking 401k distributions because you were worried about the tax hit, the new senior deduction may give you room to take more out now at a lower effective rate. And if you are considering Roth conversions, these higher deductions give you more room to convert at the bottom brackets.
Change number two. The tax bracket stayed, but the thresholds moved. As I mentioned, the seven tax brackets are now permanent. But, the income thresholds, the amounts where one bracket ends and the next begins, are adjusted for inflation every year. In 2026, those thresholds increased by approximately 2.7%. Here are the 2026 brackets for married filing jointly. The 10% bracket applies to taxable income from $0 to $25,150. The 12% bracket applies from $25,151 to $100,800. The 22% bracket applies from $100,801 to $201,050. The 24% bracket applies from $201,051 to $383,900. For single filers, the 10% bracket applies from $0 to $12,575. The 12% bracket applies from $12,576 to $51,525. The 22% bracket applies from $51,526 to $103,350. The 24% bracket applies from $103,351 to $197,300.
Here is why these numbers matter for your 401k. The jump from 12% to 22% is the biggest percentage increase in the entire bracket structure. It is a 10 percentage point leap. If you are a married couple filing jointly with taxable income of $100,000, you are entirely in the 12% bracket. If you take a $5,000 distribution from your 401k that pushes your taxable income to $105,000, that extra $5,000 is taxed at 22%, not 12%. You just paid $1,100 in tax on that $5,000 instead of $600. That is an extra $500 in taxes because you crossed the bracket line by $5,000.
This is where bracket management becomes the most important tax strategy for retirees. The goal is to take distributions that fill up the current bracket without spilling into the next one. If you have room in the 12% bracket, fill it up with distributions, Roth conversions, or extra withdrawals. Once you are close to the 22% bracket, stop. Supplement the rest of your income needs with Roth withdrawals, which are tax-free, or brokerage account withdrawals, which may be taxed at the lower capital gains rate.
Let me give you a practical example of bracket management. Robert is 67 years old, married filing jointly. His wife is 66. Both are retired. Their income sources in 2026 are Social Security of $42,000, a pension of $18,000, and they need an additional $30,000 from their retirement accounts to cover living expenses. Their total income before deductions is $90,000. After deductions of $43,500, their taxable income is $46,500. They are in the 12% bracket, which goes up to $100,800. They have room in the 12% bracket for an additional $54,300. That is $100,800 - $46,500. They could take an extra $54,300 from their traditional IRA, and every dollar of it would be taxed at 12% or less. That is an effective tax rate of 12% on money that might otherwise be taxed at 22% if they wait until RMDs force larger distributions. But if they only need $30,000 for expenses, why take more? Because of the Roth conversion opportunity. They take $30,000 for living expenses. They convert $24,000 from their traditional IRA to a Roth IRA. Their total distributions are $54,000, bringing their taxable income to $100,500, just below the 22% bracket line. The $24,000 conversion moves money from a taxable account to a tax-free account, and they paid only 12% to do it. Over time, this strategy systematically empties their traditional IRA while filling their Roth, reducing future RMDs and future tax bills.
If Robert had not done the conversion and instead waited for his RMDs to start at 73, those forced distributions on top of his Social Security and pension would push him into the 22% bracket. Every dollar in the 22% bracket costs 10 cents more than a dollar in the 12% bracket. Over a 20-year retirement with $30,000 or more in annual RMDs, the difference between 12% and 22% is tens of thousands of dollars.
For a married couple, both over 65 in 2026, the math works like this. Start with the deductions. Standard deduction, $32,300 plus additional senior deductions of $3,200 plus new senior deduction of $8,000 equals $43,500 in deductions. Then the 12% bracket goes up to $100,800. That means you can have total income of up to $144,300 and stay entirely in the 12% bracket or below. After deducting Social Security income that is not taxable, pension income, and other sources, you may have significant room to take 401k distributions at the 12% rate.
I want to emphasize something about Social Security taxation because it interacts with your 401k withdrawals in ways most people do not expect. Depending on your total income, up to 85% of your Social Security benefits can be taxable. The calculation uses a formula based on your combined income, which is your adjusted gross income plus non-taxable interest plus half of your Social Security benefits. If your combined income exceeds $44,000 as a married couple or $34,000 as a single filer, up to 85% of your Social Security becomes taxable. This means your 401k withdrawal does not just add to your taxable income directly. It also increases the percentage of your Social Security that is taxable. A $10,000 401k withdrawal might add $10,000 to your taxable income, but it might also cause an additional $8,500 of Social Security to become taxable. The effective marginal tax rate on that $10,000 withdrawal could be as high as 46% when you factor in both the income tax on the withdrawal and the additional Social Security taxation. This is called the Social Security tax torpedo, and it catches retirees who are in the income range where Social Security taxation phases in. Compare that to the 22% bracket. Any income above $144,300 is taxed at 22% or higher. The difference between $144,300 and $144,301 costs you 10 extra cents on every additional dollar. Over a $20,000 distribution that crosses the line, that is $2,000 in additional taxes.
Change number three. The 401k catch-up contribution rule for high earners. Starting in 2026, if you are 50 or older and you earn more than $145,000, your 401k catch-up contributions must be made on a Roth basis. You can no longer make pre-tax catch-up contributions. This is a significant change for high-earning workers who are still in their 50s and 60s and actively contributing to their employer plans. The standard 401k contribution limit for 2026 is $24,500 for employees under 50. If you are 50 or older, you can contribute an additional catch-up amount. For most people aged 50 and older, the catch-up contribution is $7,500, bringing the total possible contribution to $32,000. But, for people aged 60 through 63, the Secure 2.0 Act created a super catch-up contribution of $11,250, bringing the total possible contribution to $35,750 for 2026.
Here is the catch. If you earn more than $145,000, your catch-up contribution, whether it is $7,500 or $11,250, must go into a Roth 401k. You do not get the upfront tax deduction. Instead, you pay taxes on that money now, and it grows tax-free, and comes out tax-free in retirement. This feels like a loss in the short-term. You are losing a tax deduction that you used to have, but it is a significant gain in the long-term. Every dollar in your Roth 401k will never be taxed again. It grows tax-free. It comes out tax-free in retirement. And, starting in 2024, Roth 401k accounts are no longer subject to required minimum distributions during the original owner's lifetime. That means the money can stay in the Roth, growing tax-free, for as long as you live. You never have to take it out.
If you are between 60 and 63, and you earn more than $145,000, you should seriously consider maxing out the super catch-up at $11,250. Yes, you will pay taxes on that money this year, but over a 10 to 20-year retirement, the tax-free growth and tax-free withdrawals will far exceed the upfront tax cost. And because Roth withdrawals do not count as taxable income, they do not push you into a higher tax bracket, do not affect your Medicare IRMAA surcharge, and do not make more of your Social Security benefits taxable. Every dollar in the Roth is invisible to the tax system once it is in there.
Let me show you the math on why Roth catch-up contributions are actually a hidden advantage, even though they feel like a tax increase. Say you are 61 years old, earning $180,000, and you max out the super catch-up at $11,250 in your Roth 401k. Your marginal tax rate is 24%. You pay $2,700 in taxes on that $11,250 this year. That feels like a loss compared to the pre-tax deduction you used to get, but now that $11,250 grows tax-free. At a 7% average annual return, in 10 years, it becomes $22,131. In 15 years, it becomes $31,039. In 20 years, it becomes $43,530. And every dollar of that growth comes out tax-free. If you had put the same amount in a traditional pre-tax 401k and withdrawn it at a 22% rate in retirement, you would owe $9,577 in taxes on the $43,530. You saved $2,700 in taxes today, but would have owed $9,577 later. The Roth saved you $6,877 on just one year's catch-up contribution. Multiply that across four years of super catch-up contributions from age 60 to 63, and the lifetime tax savings from Roth catch-up contributions can exceed $25,000 to $30,000. That is money that stays in your pocket instead of going to the IRS.
If you earn less than $145,000, you can still make pre-tax catch-up contributions. The Roth requirement only applies to high earners. But even if you are below the threshold, you may want to consider voluntary Roth catch-up contributions for the long-term tax benefits. Your employer must offer a Roth 401k option for this to work. If they do not, ask your HR department whether they plan to add one. Under the Secure 2.0 Act, all 401k plans that allow catch-up contributions must offer a Roth option starting in 2026.
One more detail about the catch-up rule. If your employer does not yet offer a Roth 401k, the IRS has provided a transition period. Plans that do not currently offer Roth contributions have until the end of 2026 to add the option. During the transition period, all catch-up contributions can continue to be made on a pre-tax basis regardless of your income. But once your plan adds the Roth option, the $145,000 rule kicks in. Check with your plan administrator to find out where your employer stands.
Change number four. The Roth conversion window and why 2026 may be your best year. With tax rates now permanent and the new senior deduction in place, 2026 creates a unique opportunity for retirees who have not yet started required minimum distributions. If you are between 60 and 72 and you are retired or semi-retired, your income may be at its lowest point between now and when RMDs begin at 73 or 75. Lower income means a lower tax bracket. A lower tax bracket means cheaper Roth conversions. And cheaper Roth conversions mean more of your traditional retirement money can be moved to a tax-free account at the lowest possible rate.
Here is a strategy. A married couple, both 66, both retired. Their only income in 2026 is Social Security of $48,000 and a small pension of $12,000. Their total income is $60,000. After the standard deduction of $32,300, the additional senior deductions of $3,200, and the new senior deduction of $8,000, their taxable income is approximately $16,500. They are solidly in the 10% bracket. They have $600,000 in a traditional IRA. They have 7 years until RMDs begin at age 73. If they do nothing, their RMD at 73 will be approximately $22,600. Combined with their other income, that will push their taxable income into the 22% bracket.
Instead, they convert $84,000 from the traditional IRA to a Roth IRA in 2026. After deductions, this brings their taxable income to approximately $100,500, just below the top of the 12% bracket. They pay 12% or less on the entire conversion. Over 6 years, they convert $504,000 at the 12% rate, leaving only $96,000 in the traditional IRA. Their RMD at 73 drops to approximately $3,600, barely a rounding error on their tax return. And they now have $504,000 in a Roth that will grow tax-free, come out tax-free, and never generate a required minimum distribution. The total federal tax on the conversions over 6 years is approximately $60,000. If they had left the money in the traditional IRA and withdrawn it at a 22% effective rate over 20 years of retirement, the total federal tax would have been approximately $132,000. The Roth conversion strategy saved them $72,000 in lifetime federal taxes, and it saved them from IRMAA surcharges, Social Security taxation spikes, and the stress of managing ever-growing RMDs.
There is another benefit of the Roth conversion strategy that most people overlook. The money in the Roth passes to your heirs tax-free. Under the Secure Act's 10-year rule, most non-spouse beneficiaries must empty an inherited IRA within 10 years. If they inherit a traditional IRA, every dollar they withdraw is taxable income to them, often at their peak earning years when they are in the 22% or 24% bracket. If they inherit a Roth IRA, every dollar they withdraw is tax-free. Converting to Roth before you die is essentially prepaying the taxes on your children's inheritance at your lower retirement rate instead of making them pay at their higher working years rate.
This strategy only works when your income is low enough to convert at the bottom brackets. That window exists between retirement and RMD start. For most people, that window is 5 to 10 years wide. Once RMDs begin, your income goes up, your bracket goes up, and Roth conversions become more expensive. The time to act is now while the window is open.
I want to mention one more planning consideration for 2026 specifically. The new senior deduction of $4,000 per person is only available for tax years 2025 through 2028. It may or may not be extended beyond 2028. If Congress does not extend it, the extra deduction space disappears. That means the unusually large tax-free zone that exists right now may shrink in 2029. If you are planning multi-year Roth conversions, the next 3 years, 2026 through 2028, offer the most deduction. Front-loading your conversions into these years, while the senior deduction is available, could save you additional thousands of dollars compared to spreading conversions into 2029 and beyond.
Here is the summary. The One Big Beautiful Bill Act made the current tax rates permanent. The feared tax cliff did not happen, but four changes in 2026 directly affect everyone over 60 with a 401k.
First, the new senior deduction gives everyone over 65 up to $4,000 in additional deductions, or $8,000 for a married couple. This means you can withdraw more from your 401k before owing taxes.
Second, the tax bracket threshold shifted upward by 2.7%. Know your bracket. The jump from 12% to 22% is the most expensive line in the tax code. Plan your withdrawals to stay below it.
Third, high earners over 50 must make catch-up contributions to their 401k on a Roth basis starting in 2026. This costs more in taxes today, but creates tax-free income in retirement. Workers aged 60 to 63 have a super catch-up limit of $11,250.
Fourth, 2026 may be the best year for Roth conversions. With the new deductions and permanent brackets, the window to convert at the lowest rates is open right now. If you are between retirement and RMD age, every dollar you convert at 12% is a dollar you will not withdraw at 22% or higher later.
Talk to a tax professional, run the bracket math, and do not let these changes pass you by without taking action.
Here is a simple action checklist.
If you are over 65, confirm that your tax preparer is applying the new senior deduction on your 2025 and 2026 returns. If they are not, you are overpaying.
If you are between 60 and 72 with a traditional IRA or 401k, run the Roth conversion math. Calculate how much room you have in the 12% bracket after your deductions and other income. Convert up to that amount. Do this every year until RMDs start.
If you are between 60 and 63 and still working, check whether your employer offers a Roth 401k and consider the super catch-up contribution of $11,250 for 2026.
If you are already taking RMDs, coordinate your withdrawals with your Social Security income to avoid the tax torpedo zone where an extra dollar of 401k income causes an additional 85 cents of Social Security to become taxable.
And if you have a financial advisor, make sure they are planning around the IRMAA brackets as well as the income tax brackets because the Medicare surcharge acts as a hidden tax that most withdrawal calculators ignore.
