The TCJA cliff was averted: what 2026 tax brackets actually look like

Most retirement-planning content on the internet is still written as if the 2017 Tax Cuts and Jobs Act (TCJA) expired at the end of 2025 and reverted to pre-TCJA brackets. That's wrong. Congress acted. Here's what actually happened, what the 2026 brackets look like in practice, and what it means for a typical $80,000-AGI retiree compared to the doomsday scenario most blogs still warn about.

What Congress actually did

On July 4, 2025, the One Big Beautiful Bill Act (OBBBA) was signed into law. It permanently extended most of the individual income-tax provisions from TCJA that were scheduled to sunset at the end of 2025. Specifically:

• The seven-bracket structure with rates of 10 / 12 / 22 / 24 / 32 / 35 / 37 percent was made permanent. Without OBBBA, brackets would have reverted to the pre-TCJA structure with rates of 10 / 15 / 25 / 28 / 33 / 35 / 39.6 percent.
• The roughly doubled standard deduction was made permanent. Without OBBBA, the standard deduction would have been cut by approximately half and the personal exemption (eliminated by TCJA) would have been restored.
• The $2,000 Child Tax Credit was preserved (rather than reverting to $1,000).
• The $10,000 SALT deduction cap was retained.
• The estate-tax exemption at roughly twice the pre-TCJA level was preserved.

For retirees specifically, the two biggest items are the bracket structure and the larger standard deduction — both of which directly affect the tax bill on Social Security, pension income, and Traditional IRA distributions.

The 2026 brackets, officially

Per the IRS inflation-adjustment release for tax year 2026, here are the brackets after OBBBA:

Single filers

Bracket	Taxable income
10%	Up to $12,400
12%	$12,400 – $50,400
22%	$50,400 – $105,700
24%	$105,700 – $201,775
32%	$201,775 – $256,225
35%	$256,225 – $640,600
37%	Over $640,600

Married filing jointly

Bracket	Taxable income
10%	Up to $24,800
12%	$24,800 – $100,800
22%	$100,800 – $211,400
24%	$211,400 – $403,550
32%	$403,550 – $512,450
35%	$512,450 – $768,700
37%	Over $768,700

Standard deduction (2026)

Filing status	Base	Over-65 add-on
Single	$16,100	+$2,050
Married filing jointly	$32,200	+$1,650 per qualifying spouse
Head of household	$24,150	+$2,050

So a single retiree over 65 gets a $18,150 standard deduction in 2026, and a couple both over 65 filing jointly gets $35,500.

What this looks like for a typical retiree

Consider a single retiree, age 67, with $80,000 of adjusted gross income (AGI) — a typical mix of Social Security, pension income, and a modest IRA distribution. Here's the math under OBBBA versus the counterfactual where TCJA had been allowed to expire.

Scenario A: Single retiree, $80,000 AGI, age 67 (current law, post-OBBBA)

Item	Amount
AGI	$80,000
Standard deduction (single, over 65)	$18,150
Taxable income	$61,850
Tax on first $12,400 at 10%	$1,240
Tax on next $38,000 at 12%	$4,560
Tax on remaining $11,450 at 22%	$2,519
Total federal income tax	$8,319

Effective federal rate: about 10.4%.

Scenario B: Same retiree, alternate-history where TCJA expired

If TCJA had been allowed to expire, three things would have happened simultaneously:

1. The standard deduction would have been cut roughly in half (to approximately $8,100 for single, plus a ~$1,750 over-65 add-on).
2. The personal exemption (worth approximately $4,800 in 2026 dollars) would have been restored.
3. Bracket rates would have reverted: 10 / 15 / 25 / 28 / 33 / 35 / 39.6 percent. Bracket thresholds also would have changed.

Item	Amount
AGI	$80,000
Standard deduction (single, over 65, pre-TCJA equivalent)	~$9,850
Personal exemption	~$4,800
Taxable income	~$65,350
Tax (10% on ~$10,800, 15% on ~$32,400, 25% on remainder)	~$11,500
Total federal income tax	~$11,500

Effective federal rate: about 14.4%.

The actual delta

For this retiree, OBBBA saves roughly $3,200 per year compared to the alt-history where TCJA expired. Over a 25-year retirement horizon, in nominal dollars, that's around $80,000 of cumulative tax savings — meaningful for a household at this income level.

What about a couple?

For a couple both over 65, filing jointly, with $80,000 of combined AGI:

Item	Amount
AGI	$80,000
Standard deduction (MFJ, both over 65)	$35,500
Taxable income	$44,500
Tax on first $24,800 at 10%	$2,480
Tax on remaining $19,700 at 12%	$2,364
Total federal income tax	$4,844

Effective federal rate: about 6.1%.

A couple at this AGI level is comfortably in the 12% bracket and pays less than $5,000 in federal income tax. This is the bracket where Roth conversions during the retirement-to-RMD trough years can be highly tax-efficient — converting up to the top of the 12% bracket costs you less than 12 cents on the dollar in federal tax (and often nothing in state tax, depending on residency).

What didn't change

Several things that retirees rely on were not affected by OBBBA, which is worth flagging because their statutory amounts haven't been inflation-adjusted in decades:

• Social Security taxability thresholds remain at the 1983/1993 statutory amounts: $25,000 / $34,000 for single, $32,000 / $44,000 for joint. These determine whether 0%, 50%, or 85% of your Social Security benefit becomes taxable. They have never been indexed for inflation. As a result, far more retirees pay tax on their Social Security than was originally intended — and that's not changing.

• The "tax torpedo" — the effect where adding $1 of ordinary income raises your taxable income and makes more of your Social Security taxable — is still in full effect. A retiree in the 12% bracket can face an effective marginal rate of 22.2% (12% × 1.85, where 1.85 reflects the additional taxability of SS) on the next dollar of withdrawal or conversion. OBBBA did nothing about this.

• The Net Investment Income Tax (NIIT) of 3.8% on investment income above $200,000 single / $250,000 joint MAGI remains in place. These thresholds have also never been inflation-adjusted.

• IRMAA Medicare surcharges are inflation-adjusted by CMS each year and continue to apply at the same MAGI bracket cutoffs (with annual updates). The 2026 first-tier threshold is approximately $103,000 for single filers and $206,000 for joint filers — these are the points where Part B premiums begin to rise above the standard amount.

What this means for retirement planning in 2026

Three takeaways:

1. The "tax cliff" panic from 2024–2025 retirement-planning content is now outdated. If you're reading a blog or watching a video that warns about brackets reverting to 15% / 25% / 28% in 2026, the author hasn't updated since OBBBA passed. Discount accordingly.

2. The Roth conversion math from 2024–2025 is still mostly right. Conversions in the trough years between retirement and RMD age (73 under SECURE 2.0) are still highly tax-efficient because the 12% and 22% brackets are wide. If anything, OBBBA strengthens the case for ladders because the savings you'd accrue from converting at today's rates won't be eroded by reversion in 2026.

3. The Social Security and NIIT thresholds remain the bigger structural problem for moderate-income retirees. The tax torpedo is still real. If your projected retirement AGI is in the $30,000–$50,000 range, a careful look at how much of your SS becomes taxable as you draw down — and how to avoid pushing through the 50%-to-85% threshold — is worth more than worrying about bracket reversion.

Frequently asked questions

Did OBBBA change Social Security taxation?

No. The thresholds that determine whether 0%, 50%, or 85% of your Social Security benefit becomes taxable were set by statute in 1983 and amended in 1993. They have never been inflation-adjusted and OBBBA did not change them. This means the share of retirees paying tax on Social Security continues to grow each year as nominal incomes rise.

Are the 2026 brackets the final answer, or could they still change?

OBBBA made the individual bracket structure permanent. "Permanent" in tax-policy terms means "no scheduled sunset" — Congress can always change it again with new legislation. But absent further action, the bracket structure as shown above is the law going forward.

What about the SALT cap?

The $10,000 cap on the State and Local Tax (SALT) itemized deduction was retained by OBBBA. This continues to disadvantage residents of high-tax states (California, New York, New Jersey, Massachusetts, etc.) compared to residents of low-tax or no-income-tax states.

Did the Child Tax Credit change?

OBBBA permanently set the Child Tax Credit at $2,000 per qualifying child (rather than allowing it to revert to $1,000). For retirees this matters only if you have dependent children or grandchildren you claim — uncommon but not rare.

Are state tax brackets affected?

OBBBA is a federal law. State tax brackets and rules are determined by each state's legislature and are unaffected by federal bracket changes. Many states have their own retirement-income carve-outs (Pennsylvania, for example, doesn't tax pension or IRA distributions) — see our state retirement tax pages for the rules where you live.

See your specific situation

The brackets, the standard deduction, and the over-65 add-on are the easy part. What gets complicated is the interaction of bracket math with Social Security taxation, IRMAA surcharges, RMDs, and state rules. Yearfold runs all of that automatically — including the worked example math from this post — using your actual numbers and the actual 2026 federal rules.
