Every January, the tax rules shift. New numbers. New caps. New deductions. And if you're in or near retirement, it feels like the game keeps changing just as you're getting the hang of it.
Here's the good news: the core strategies for retirement tax planning don't change. What changes are the details, the limits, the phase-outs, the numbers you plug into your plan. Think of it like this: the engine of your car is the same. We're just adjusting the tuning.
This isn't about starting over. It's about making sure your plan reflects what's actually true in 2026.
Let's walk through what shifted, what it means for you, and what (if anything) you should adjust right now.
The 60-Second Takeaway
What changed in 2026: New deductions for seniors 65+, higher IRA contribution limits, a bigger SALT deduction cap, and some tricky AMT rule reversions that could surprise higher earners.
What didn't change: The principles of tax-efficient retirement planning, use the right buckets, minimize what you owe, protect what you've built, and plan for what happens next.
What to do: Run a quick audit (see below) to see if any of these changes give you a new opportunity or expose a blind spot.

The Layered Question: What Actually Changed?
Layer 1: What's different about taxes in 2026?
Several rules got updated. Some help. Some hurt. Here are the big ones:
1. A brand-new deduction for people 65 and older
If you're 65 or older, you now get an extra $6,000 deduction ($12,000 if you're married filing jointly). This is on top of the standard deduction.
That means:
- Single filer over 65: $24,150 total deduction (standard + senior)
- Married filing jointly over 65: $44,200 total deduction
But there's a catch: it phases out if your modified adjusted gross income (MAGI) is too high. For single filers, it starts shrinking at $75,000 and disappears at $175,000. For married couples, it phases out between $150,000 and $250,000.
2. Higher IRA contribution limits
You can now contribute $7,500 to your IRA (up from $7,000 in 2025). That's $500 more you can shelter from taxes this year.
3. A bigger SALT deduction cap
The cap on state and local tax (SALT) deductions jumped to $40,400 for 2026 (from $10,000). If you itemize and you live in a high-tax state, this is huge. But it phases out at higher incomes and expires in 2030.
4. AMT thresholds dropped
The Alternative Minimum Tax (AMT) exemption phase-out thresholds reverted to lower levels. If you're a higher earner, you might suddenly owe AMT when you didn't before. The phase-out now starts at $500,000 for singles and $1,000,000 for married couples (down from over $1.2 million).
5. Social Security bumps
A 2.8% cost-of-living adjustment (COLA) kicked in for Social Security beneficiaries. The maximum taxable earnings for Social Security also increased to $184,500.
This isn't a failure or something you missed. Tax rules change every year. If you haven't revisited your retirement tax planning strategies in the last 12 months, you're not behind, you're just due for a tune-up.
Layer 2: Why does this matter for my plan?
Here's where it gets practical.
If you're 65 or older with income under the phase-out limits, that new $6,000 deduction could mean serious savings, potentially $1,000+ in taxes you don't have to pay. But if you're taking large withdrawals from a traditional IRA or 401(k), those withdrawals count as income and could push you over the limit.
If you're still contributing to retirement accounts, the higher IRA limit gives you a little more room to shelter income this year. It's not life-changing, but over time, these incremental increases compound.
If you live in a high-tax state, the expanded SALT deduction might make itemizing worth it again. That changes the math on charitable giving, mortgage interest, and other deductions.
And if you're a higher earner, the AMT reversion means you need to check whether you're now subject to AMT rules you weren't last year. This affects things like timing of income, Roth conversions, and even capital gains harvesting.

Layer 3: What should I actually do about it?
You don't need to overhaul your plan. You need to check the alignment.
Here's the mechanic view: every year, the tax code gets a software update. If your plan was built on last year's numbers, it might be running on old settings. We're just making sure everything's calibrated.
For tax advantaged retirement savings:
- If you're 65+, check your projected MAGI. If you're under the phase-out limits, you just got a bigger deduction. If you're above them, consider whether Roth conversions or timing withdrawals differently could help.
- If you're still working and contributing, max out that $7,500 IRA limit if you can.
For legacy planning and probate:
- Nothing changed here in terms of rules, but higher account balances (thanks to market gains and contributions) mean it's a good time to review beneficiary designations. If you haven't updated them in a while, Use our Beneficiary Update Checklist to make sure your assets go to the right people.
- Probate isn't about 2026 rules, it's about how your assets are titled. Learn how to avoid probate and protect your family from delays and unnecessary costs so your plan matches your intentions.
For higher earners:
- Run an AMT projection. If you're suddenly subject to AMT, it changes the value of certain deductions and the timing of income recognition.
- The expanded SALT cap might make itemizing attractive again. Compare your total itemized deductions to the standard deduction and see which saves you more.

Answer Box: The Core Concept
What changed: Specific numbers, deductions, caps, limits, phase-outs.
What didn't change: The strategy. You still want to:
- Pay less tax over your lifetime (not just this year)
- Use the right account types for the right purposes
- Coordinate withdrawals to stay in favorable tax brackets
- Protect what you've built from probate and unnecessary costs
- Make sure beneficiaries are updated
The bottom line: Think of 2026 as a tune-up year, not a rebuild year.
One Quick Audit: What to Check This Week
You don't need to spend hours on this. Set a timer for 10 minutes and check these three things:
1. Your projected MAGI for 2026
Pull up last year's tax return. Look at your modified adjusted gross income (MAGI). Add in any expected changes, new withdrawals, different Social Security amounts, capital gains, etc.
Ask yourself:
- Am I over 65? If yes, does my MAGI fall under the phase-out limits for the new senior deduction?
- Could I adjust the timing of withdrawals or Roth conversions to stay under the limit?
2. Your itemized vs. standard deduction
With the higher SALT cap, itemizing might make sense again if you live in a high-tax area.
Add up:
- State and local taxes (up to $40,400)
- Mortgage interest
- Charitable contributions
- Medical expenses (if over 7.5% of AGI)
Compare that total to your standard deduction. Use whichever is higher.
3. Your beneficiary designations
This has nothing to do with 2026 rules, but if you're doing a financial tune-up, this is the time. Pull out your IRA, 401(k), and life insurance statements. Check who's listed as primary and contingent beneficiaries.
Out-of-date beneficiaries are one of the easiest ways to accidentally send assets through probate: even if you have a will or trust. (Learn how to avoid probate and protect your family from delays and unnecessary costs.)

What Hasn't Changed (And Why That Matters)
Tax rules change every year. The principles don't.
You still want to:
- Minimize lifetime taxes, not just this year's taxes
- Use the right buckets (taxable, tax-deferred, tax-free) in the right order
- Plan for required minimum distributions (RMDs) before they become a problem
- Coordinate Social Security timing with your tax situation
- Protect your legacy by keeping beneficiaries updated and using strategies that avoid probate
The 2026 changes don't rewrite the playbook. They just give you a few new tools and a couple of new numbers to plug in.
If you've been following solid retirement tax planning strategies, you're not starting over. You're just making small adjustments to keep things running smoothly.
The Real Question
The real question isn't "What changed in 2026?"
It's: "Is my plan still aligned with what's actually true right now?"
If you haven't looked at your retirement tax plan in the last year, the answer is probably "mostly, but not quite."
And that's okay. That's why we do tune-ups.
You don't need to be an expert. You just need to know what to check: and when to bring in a second set of eyes.

But for now? Just run that quick audit. Check your numbers. Make sure nothing's wildly out of alignment.
That's all a tune-up is.
