For the 2026 tax year, OBBBA made TCJA provisions permanent and introduced several new deductions that directly affect how much you'll get back — or owe — at tax time.

1. What Is OBBBA and Why It Matters
The TCJA's individual tax provisions were scheduled to sunset on December 31, 2025. Without congressional action, 62% of taxpayers would have faced higher taxes starting in 2026 — the largest federal tax increase in a generation.
OBBBA didn't just extend those provisions. It made them permanent and added several new deductions that create both planning opportunities and compliance complexity for the 2026 tax year and beyond.
For your refund calculation, this matters in three ways:
- Your 2026 brackets are permanent — no scheduled reversion to higher rates
- New deductions are available — tips, overtime, seniors, auto loan interest
- Some deductions increased — SALT cap raised, Child Tax Credit doubled
2. The Five OBBBA Changes That Affect Your Refund
| OBBBA Provision | What Changed | Impact on 2026 Refund |
|---|---|---|
| TCJA brackets permanent | Prevents reversion to higher rates | Larger refunds for 62% of taxpayers |
| SALT cap raised | $10,000 → $40,400 | Larger refunds for itemizers in high-tax states |
| Child Tax Credit doubled | $1,000 → $2,200 per child | Larger refunds for families |
| Tip income deduction | New (temporary) | Larger refunds for tipped workers |
| Overtime pay deduction | New (temporary) | Larger refunds for hourly workers |
| Senior deduction | New $2,000 | Larger refunds for taxpayers 65+ |
3. SALT Cap Increased to $40,400
The single most impactful change for upper-middle-income clients in high-tax states. The state and local tax deduction cap, which had been $10,000 since 2018, jumps to $40,400 for most taxpayers in 2026.
How it works:
- If you itemize, you can deduct up to $40,400 in combined state income + property + sales taxes
- Single filers with MAGI above $500,000 and married filers above $1,000,000 face a phaseout
- The phaseout reduces the cap back to $10,000 for the highest earners
Example: A California family with $200,000 income paying $15,000 in state income tax and $8,000 in property tax can now deduct the full $23,000 (vs only $10,000 under the old cap). This saves them approximately $2,860 in federal tax (22% bracket × $13,000 additional deduction).
4. Child Tax Credit Doubled to $2,200
OBBBA brings the Child Tax Credit to $2,200 per qualifying child for 2026, doubled from pre-TCJA levels and indexed to inflation going forward. The refundable portion (Additional Child Tax Credit) increases to $1,700.
Key details:
- Maximum credit: $2,200 per qualifying child under 17
- Refundable portion: up to $1,700
- Phaseout: $200,000 (single) / $400,000 (married) MAGI
- Phaseout rate: $50 reduction per $1,000 over threshold
Example: A family with 3 children saves $3,600 compared to pre-TCJA law (3 × $1,200 increase = $3,600). See our OBBBA tax calculator for your specific numbers.
5. New Tip Income Deduction
Qualifying tipped income earned in traditionally tipped occupations becomes partially deductible. This is a temporary provision scheduled to sunset in future years.
Who benefits:
- Restaurant servers
- Bartenders
- Hospitality staff
- Hair stylists
- Other traditionally tipped occupations
How it works:
- Qualifying tip income is partially deductible from federal taxable income
- Documentation required (Form 4137 or Form 4070)
- The IRS will likely scrutinize this new deduction closely
Impact: Particularly valuable in states like Florida, Nevada, and Tennessee where service economies are large.
6. New Overtime Pay Deduction
Qualifying overtime pay — paid at time-and-a-half for hours beyond 40 per week — becomes partially deductible. Like the tip deduction, this is temporary.
Who benefits:
- Manufacturing workers
- Healthcare workers
- Logistics workers
- Hourly employees who regularly earn overtime
How it works:
- Qualifying overtime pay is partially deductible
- Effectively increases take-home pay without changing gross wages
- Important for cash flow planning
7. New Senior Additional Deduction
Taxpayers 65 and older can claim an additional $2,000 deduction on top of the standard deduction.
Combined benefit for seniors:
- Standard deduction (single): $16,100
- Additional standard deduction (65+): ~$1,950
- New OBBBA senior deduction: $2,000
- Total deduction: ~$20,050 (vs $16,100 for under 65)
This is particularly valuable for retirees with pension or IRA distribution income.
8. OBBBA vs Prior Law: Worked Comparison
Let's compare a 2026 refund under OBBBA versus what it would have been under pre-TCJA law (the law that would have applied if OBBBA hadn't passed).
Scenario: Single filer, $75,000 salary, $8,500 federal withholding, 1 child under 17.
Under OBBBA (2026)
Step 1: Taxable income
- Gross: $75,000
- Standard deduction: −$16,100
- Taxable income: $58,900
Step 2: Tax brackets (TCJA permanent)
- 10% on $11,925 = $1,192.50
- 12% on $11,925–$47,750 = $4,318.50
- 22% on $47,750–$58,900 = $2,453.00
- Tax: $7,964.00
Step 3: Credits
- Child Tax Credit (OBBBA): −$2,200
- Total tax: $5,764.00
Step 4: Refund
- Withholding: $8,500
- Tax owed: $5,764
- Refund: $2,736
Under Pre-TCJA Law (Without OBBBA)
Step 1: Taxable income
- Gross: $75,000
- Standard deduction (lower): −$8,000
- Personal exemptions (taxpayer + child): −$10,600
- Taxable income: $56,400
Step 2: Tax brackets (pre-TCJA, higher rates)
- 10% on $11,000 = $1,100
- 15% on $11,000–$44,700 = $5,055
- 25% on $44,700–$56,400 = $2,925
- Tax: $9,080.00
Step 3: Credits
- Child Tax Credit (pre-TCJA): −$1,000
- Total tax: $8,080.00
Step 4: Refund
- Withholding: $8,500
- Tax owed: $8,080
- Refund: $420
Comparison
| Scenario | Tax Owed | Refund |
|---|---|---|
| Under OBBBA (2026) | $5,764 | $2,736 |
| Under Pre-TCJA Law | $8,080 | $420 |
| OBBBA Advantage | $2,316 less tax | $2,316 larger refund |
This taxpayer saves $2,316 in taxes thanks to OBBBA — a 29% reduction in tax liability.
9. Average Impact by Income Group
According to Tax Foundation analysis, OBBBA increases after-tax income by an average of 5.4% in 2026 compared to letting the TCJA expire. The distribution varies meaningfully by income quintile:
| Income Quintile | After-Tax Income Increase | Estimated Refund Impact |
|---|---|---|
| Bottom 20% | +2.6% | Small refund increase |
| 20th-40th percentile | +4.1% | Moderate refund increase |
| 40th-60th percentile | +5.2% | Significant refund increase |
| 60th-80th percentile | +6.3% | Largest refund increase |
| Top 20% | +5.8% | Significant refund increase |
The middle and upper-middle quintiles see the largest benefits — primarily because they have enough income to benefit from the bracket structure but not so much that phaseouts eliminate the gains.
10. Who Benefits Most from OBBBA
Families with children: The doubled Child Tax Credit ($2,200 per child) provides substantial savings. A family with 3 children saves $3,600+ compared to pre-TCJA law.
Upper-middle-income itemizers in high-tax states: The SALT cap increase from $10,000 to $40,400 provides major relief for taxpayers in California, New York, New Jersey, Connecticut, and Illinois.
Tipped workers: The new tip income deduction provides meaningful after-tax income increases for service industry workers.
Hourly workers with overtime: The new overtime deduction increases take-home pay for regular overtime earners.
Seniors 65+: The new $2,000 senior deduction, combined with the existing additional standard deduction, provides extra tax relief.
11. Who Doesn't Benefit from OBBBA
Very high earners (MAGI > $500K single / $1M married): The SALT cap phaseout eliminates the benefit of the increased cap.
Non-itemizers in low-tax states: If you take the standard deduction and live in a no-income-tax state (Texas, Florida, etc.), the SALT cap increase doesn't help you.
Households without children: The Child Tax Credit doesn't apply, though other OBBBA benefits (brackets, standard deduction) still help.
Taxpayers in the 0% bracket: If your income is below the standard deduction, OBBBA's bracket changes don't affect your federal tax (already $0).
12. Frequently Asked Questions
What is OBBBA? The One Big Beautiful Bill Act, a 2025 federal tax law that made TCJA individual tax cuts permanent and added new deductions for tips, overtime, seniors, and auto loan interest.
How does OBBBA affect my 2026 tax refund? OBBBA prevents bracket reversion to higher rates, doubles the Child Tax Credit to $2,200, raises the SALT cap to $40,400, and adds new deductions. Most taxpayers will see larger refunds in 2026.
When do OBBBA changes take effect? Most provisions take effect starting January 1, 2026 (for the 2026 tax year, filed in early 2027).
