2026 Federal Tax Brackets: Why the TCJA Didn't Sunset After All
2026 Federal Tax Brackets: Why the TCJA Didn't Sunset After All
For years, tax professionals circled January 1, 2026 on their calendars. That was the date the individual provisions of the Tax Cuts and Jobs Act (TCJA) were set to expire, reverting federal income tax rates to the higher pre-2018 structure. Financial advisors built entire planning strategies around the assumption that the top rate would jump from 37% back to 39.6%, the standard deduction would shrink, and personal exemptions would return.
Then the One Big Beautiful Bill Act (OBBB), signed July 4, 2025, made most of those TCJA provisions permanent. The cliff never came.
Here's what the 2026 federal tax landscape actually looks like — and how it compares to the world that almost was.
The 2026 Brackets: What You'll Actually Pay
The OBBB extended and made permanent the TCJA's seven-bracket structure. Here are the 2026 rates for single filers, adjusted for inflation:
| Tax Rate | Taxable Income (Single) |
|---|---|
| 10% | Up to $11,925 |
| 12% | $11,926 – $48,475 |
| 22% | $48,476 – $103,350 |
| 24% | $103,351 – $197,300 |
| 32% | $197,301 – $250,525 |
| 35% | $250,526 – $626,350 |
| 37% | Over $626,350 |
For married filing jointly, each threshold is roughly doubled (e.g., the 37% rate kicks in above $751,600).
What Would Have Happened Without the OBBB
If Congress had done nothing and let the TCJA expire, 2026 would have looked dramatically different. The old pre-TCJA structure had seven brackets too, but at higher rates with different breakpoints:
| Tax Rate | Taxable Income (Single, Pre-TCJA) |
|---|---|
| 10% | Up to ~$9,525 |
| 15% | $9,526 – ~$38,700 |
| 25% | $38,701 – ~$93,700 |
| 28% | $93,701 – ~$195,450 |
| 33% | $195,451 – ~$424,950 |
| 35% | $424,951 – ~$426,700 |
| 39.6% | Over ~$426,700 |
(Pre-TCJA thresholds shown at approximate 2026 inflation-adjusted levels.)
Side-by-Side Comparison for a Single Filer Earning $100,000
| Scenario | Approximate Federal Income Tax |
|---|---|
| 2026 Actual (TCJA preserved) | ~$15,100 |
| 2026 Sunset (pre-TCJA rates) | ~$17,800 |
| Difference | ~$2,700 more under sunset |
For a $200,000 single filer, the difference would be roughly $5,400. The savings come from the lower rates in the middle brackets (12% vs 15%, 22% vs 25%, 24% vs 28%) where most of your income actually falls.
The Standard Deduction Stayed High
The other major TCJA provision people worried about losing was the enlarged standard deduction. Under pre-TCJA law, the standard deduction for a single filer in 2026 would have been approximately $8,300, supplemented by a personal exemption of around $5,300 — for a combined $13,600 in non-taxable income.
Under the OBBB-extended rules, the 2026 standard deduction is:
- $16,100 for single filers
- $32,200 for married filing jointly
- $23,500 for head of household
No personal exemptions (they remain eliminated), but the higher standard deduction more than compensates for most filers. The crossover point where the old system would have been better is roughly $150,000+ in income with significant itemizable deductions — and even that math changed with the new $40,400 SALT cap.
What Else the OBBB Preserved (and Changed)
Child Tax Credit: $2,000 (Unchanged)
The Child Tax Credit stays at $2,000 per qualifying child, with up to $1,700 refundable. There was significant lobbying to increase it — early proposals ranged from $2,500 to $3,600 — but the final bill kept it at the TCJA level. The phase-out begins at $200,000 MAGI ($400,000 joint), which is the same threshold since 2018 and is not indexed to inflation.
Qualified Business Income (QBI) Deduction: Extended
The Section 199A deduction — the 20% deduction for pass-through business income — was set to expire. The OBBB made it permanent. If you're a sole proprietor, partner, or S-corp shareholder, you can continue deducting up to 20% of qualified business income, subject to the existing wage and capital limitations at higher incomes.
Estate Tax Exemption: $15 Million (Permanent)
The TCJA doubled the estate tax exemption, but it was scheduled to revert to approximately $7 million in 2026. Instead, the OBBB raised it to $15 million per person and made it permanent, indexed to inflation. This is the single largest change for high-net-worth families. We cover this in detail in our estate tax article.
Alternative Minimum Tax (AMT)
The TCJA's higher AMT exemption amounts were also made permanent. The 2026 AMT exemption is $88,100 for single filers and $137,000 for married filing jointly. The phase-out threshold starts at $626,350 (single). This means the AMT continues to affect far fewer taxpayers than it did pre-2018.
What This Means in Practice
For the vast majority of taxpayers, the 2026 tax year looks a lot like 2024 and 2025 — same rate structure, same general approach, adjusted for inflation. The "TCJA cliff" that dominated tax planning conversations for years turned out to be a non-event.
That said, the OBBB added new complexity on top of the preserved brackets. The six new deductions (tips, overtime, car loan interest, senior bonus, SALT increase, and Trump Accounts) interact with these brackets in ways that can shift your effective rate. A server earning $50,000 with $15,000 in tips, for example, now has an effective taxable income of $35,000 — dropping from the 22% bracket solidly into the 12% bracket.
The brackets are the foundation, but the real 2026 story is in the deductions layered on top of them.
