What Is the One Big Beautiful Bill?
The One Big Beautiful Bill Act (OBBBA) is the most significant federal tax legislation since the Tax Cuts and Jobs Act of 2017. Signed into law in July 2025, it is a comprehensive tax and spending package that made the TCJA's individual tax cuts permanent, introduced five brand-new above-the-line deductions, raised the Child Tax Credit, increased the SALT deduction cap, and restructured several provisions that were set to expire after 2025.
Without the OBBBA, the seven income tax brackets would have reverted to the higher pre-2018 rates of 10%, 15%, 25%, 28%, 33%, 35%, and 39.6% starting in 2026. The standard deduction would have been cut roughly in half. The Child Tax Credit would have dropped from $2,000 back to $1,000. For most American taxpayers, the OBBBA prevented a substantial tax increase that was already scheduled under existing law.
The new law goes beyond simply extending the status quo. The five new deductions target specific groups — tipped workers, overtime earners, car buyers, seniors, and homeowners in high-tax states — with above-the-line deductions that reduce adjusted gross income directly. These deductions are claimed on the new Schedule 1-A form and are available regardless of whether you take the standard deduction or itemize.
The Five New Above-the-Line Deductions
The OBBBA created five new deductions that are claimed above the line on Schedule 1-A, meaning they reduce your adjusted gross income (AGI) before you decide whether to take the standard deduction or itemize. This makes them available to virtually all eligible taxpayers.
1. No Tax on Tips (up to $25,000).Workers who receive tips as part of their compensation can deduct up to $25,000 in tip income from their AGI. This applies to cash tips, credit card tips, and allocated tips reported on Form W-2. The deduction is available to employees in traditionally tipped occupations — servers, bartenders, hairstylists, delivery drivers, and similar roles. The income must be reported as tips on your W-2 or Schedule C. This provision alone can save a full-time server earning $30,000 in tips between $1,800 and $5,500 in federal taxes depending on their bracket.
2. No Tax on Overtime (up to $12,500).Overtime premium pay — the additional amount above your regular hourly rate for hours worked beyond 40 per week — is deductible up to $12,500. If your regular rate is $25/hour and you earn $37.50/hour for overtime, the $12.50 premium per overtime hour qualifies. This does not cover your full overtime pay, only the premium portion. Workers who regularly log 10 or more overtime hours per week can save $1,500 to $2,750 annually.
3. Car Loan Interest Deduction (up to $10,000). Interest paid on auto loans for new vehicles purchased after July 2025 is deductible up to $10,000 per year. The vehicle must be new (not used), purchased for personal use, and the loan must be in the taxpayer's name. At a 7% interest rate on a $40,000 loan, first-year interest is approximately $2,600, saving roughly $570 to $960 in federal taxes depending on your bracket.

4. Senior Standard Deduction Bonus ($6,000). Taxpayers aged 65 or older with income below $75,000 (single) or $150,000 (married filing jointly) receive an additional $6,000 standard deduction bonus. This is on top of the existing additional standard deduction for seniors ($2,000 for single filers, $1,600 for married). A qualifying single senior now receives $15,000 + $2,000 + $6,000 = $23,000 in total standard deduction, effectively making the first $23,000 of income tax-free.
5. SALT Cap Increase ($10,000 to $40,000). The state and local tax (SALT) deduction cap, which was set at $10,000 by the TCJA, has been raised to $40,000. This benefits homeowners in high-tax states like New York, New Jersey, California, Connecticut, and Illinois who pay significant state income taxes and property taxes. A homeowner paying $15,000 in property taxes and $12,000 in state income tax can now deduct the full $27,000 instead of being capped at $10,000.
Permanent TCJA Provisions: Brackets, Standard Deduction, CTC
The OBBBA made the TCJA's lower tax rates and wider brackets permanent. The seven rates — 10%, 12%, 22%, 24%, 32%, 35%, and 37% — will remain in effect indefinitely, with income thresholds adjusted for inflation each year. Without the OBBBA, these rates would have reverted to the pre-2018 structure after 2025, resulting in higher taxes for nearly every income level.
The standard deduction amounts established by the TCJA are also now permanent. For 2025, the standard deduction is $15,000 for single filers, $30,000 for married filing jointly, and $22,500 for head of household. These amounts will continue to be adjusted for inflation annually. The near-doubling of the standard deduction was one of the TCJA's most impactful provisions, and its permanence means approximately 90% of taxpayers will continue to take the standard deduction rather than itemizing.
The Child Tax Credit (CTC) was increased from $2,000 to $2,200 per qualifying child under age 17. The refundable portion — the Additional Child Tax Credit (ACTC) — was raised to $1,700, meaning families with little or no tax liability can receive up to $1,700 per child as a direct refund. Without the OBBBA, the CTC would have dropped to $1,000 with a maximum refundable amount of $1,000 after 2025.
What Didn't Change: FICA, AMT Basics, State Taxes
Despite the sweeping nature of the OBBBA, several important parts of the tax code were not affected. FICA tax rates remain unchanged at 7.65% for employees (6.2% Social Security + 1.45% Medicare), with employers paying a matching 7.65%. Self-employment tax is still 15.3% on net self-employment earnings. The Social Security wage base continues to be adjusted for inflation ($176,100 for 2025).
The Alternative Minimum Tax (AMT) exemption amounts continue to be adjusted for inflation under the TCJA framework that the OBBBA made permanent. For 2025, the AMT exemption is $88,100 for single filers and $137,000 for married filing jointly. The TCJA's higher AMT exemptions mean far fewer taxpayers are subject to AMT than before 2018, and the OBBBA ensures this remains the case.
State income taxes are not directly affected by the OBBBA. Each state must decide independently whether to conform to the new federal provisions. Some states automatically adopt federal AGI as their starting point and may inherit some OBBBA changes without additional legislation. Others decouple from federal law and would need to pass their own bills to offer equivalent deductions. One notable change: the IRS Direct File program was eliminated under the OBBBA, meaning taxpayers who used that free filing tool will need to find an alternative for 2025 returns.
Who Benefits Most from the New Law?
The OBBBA's new deductions are targeted, and some groups benefit far more than others. Tipped workers stand to gain the most on a percentage basis — a server earning $35,000 in tips can save $1,800 to $5,500 in federal income taxes, which represents a 5% to 16% effective raise. Hourly workers who regularly earn overtime can save $1,500 to $2,750 per year with the overtime premium deduction. Use our No Tax on Tips Calculator to estimate your personal savings.
New car buyers financing their purchase benefit from the car loan interest deduction, though the savings are modest compared to the other provisions — typically $500 to $1,000 in the first year of the loan. Seniors aged 65 and older with income below $75,000 (single) or $150,000 (joint) see substantial benefit from the $6,000 bonus standard deduction, potentially saving $660 to $1,320 depending on their bracket.
Homeowners in high-tax states benefit enormously from the SALT cap increase. A family in New Jersey paying $18,000 in property taxes and $10,000 in state income taxes was previously limited to a $10,000 SALT deduction. Under the OBBBA, they can deduct the full $28,000, saving an additional $3,960 to $6,660 depending on their marginal bracket. Families with children under 17 benefit from the CTC increase, gaining an additional $200 per child per year.
How to Claim the New Deductions: Schedule 1-A
All five new deductions are reported on the new Schedule 1-A (Additional Above-the-Line Deductions), which was added to the Form 1040 package for the 2025 tax year. The form has separate line items for each deduction: tip income (Line 1), overtime premium pay (Line 2), auto loan interest (Line 3), senior standard deduction bonus (Line 4), and the SALT cap increase is handled through the existing Schedule A but with the updated $40,000 limit.
Because these are above-the-line deductions, they reduce your adjusted gross income regardless of whether you take the standard deduction or itemize. This is a significant advantage — most deductions require itemizing, which only about 10% of taxpayers do. The tip, overtime, car loan interest, and senior bonus deductions flow from Schedule 1-A to Line 10 of Form 1040, reducing your AGI before the standard deduction or itemized deduction is applied.
If you use tax preparation software, the process is straightforward. TurboTax, H&R Block, FreeTaxUSA, and other major providers have all updated their 2025 products to include Schedule 1-A. The software will ask you questions about tip income, overtime pay, auto loans, and your age to determine which deductions you qualify for and will complete Schedule 1-A automatically. If you file by hand, you can download Schedule 1-A and its instructions from IRS.gov.
Frequently Asked Questions
When did the OBBBA take effect?
The One Big Beautiful Bill Act was signed into law in July 2025. Most tax provisions, including the five new above-the-line deductions and the permanent extension of TCJA rates, apply to the 2025 tax year and forward. You can claim the new deductions when you file your 2025 return in early 2026.
Do I need to do anything different when filing my 2025 return?
If you qualify for any of the five new deductions, you will need to complete the new Schedule 1-A form. Most tax software includes it automatically when it detects eligible income or expenses. If you file by hand, download Schedule 1-A from IRS.gov. Beyond that, the filing process is the same as prior years — the changes are built into the existing Form 1040 structure.
Are the new deductions from the OBBBA permanent?
Not all of them. The tip and overtime deductions have a sunset date and are scheduled to expire after 2028 unless Congress extends them. The car loan interest deduction expires after 2030. The senior standard deduction bonus and the increased SALT cap ($40,000) are permanent with no scheduled expiration. The TCJA bracket rates are also now permanently extended.
Does the OBBBA affect state income taxes?
The OBBBA is a federal law and does not directly change state tax rules. However, states that conform to the federal definition of adjusted gross income may automatically adopt some provisions. Other states decouple from federal law and would need separate legislation. Check with your state's department of revenue for specific conformity details.
Where can I find the new Schedule 1-A form?
Schedule 1-A (Additional Above-the-Line Deductions) is available on IRS.gov under Forms and Publications. It was released in final form in December 2025 for the 2025 tax year. All major tax software providers include it in their 2025 filing products. The form has separate line items for tips, overtime premium, car loan interest, and the senior bonus deduction.
