Key tax provisions in the One Big Beautiful Bill Act
Dear Client,
We are writing to inform you of significant developments in federal tax legislation. On July 4, 2025, President Trump signed into law the One Big Beautiful Bill Act (OBBBA), a reconciliation package that includes a broad array of tax provisions affecting individuals, businesses and international taxpayers.
We want to highlight the key provisions and offer preliminary insights into how they may affect your tax planning. We will continue to closely monitor any potential regulatory guidance as it’s developed from the IRS and update you accordingly.
Individual income tax provisions
· Permanent extension of lower tax rates and brackets: The OBBBA generally makes the tax rates enacted in 2017 in the Tax Cuts and Jobs Act (TCJA) permanent. An additional year of inflation adjustment is added for determining the dollar amounts at which the 12% rate bracket ends and the 22% rate bracket begins.
· Standard deduction: The nearly doubled standard deduction would be made permanent. Effective for 2025, the amounts are as follows:
Single & Married Filing Separately (MFS): $15,750 (indexed)
Head of Household (HoH): $23,625 (indexed)
Married Filing Jointly (MFJ): $31,500 (indexed)
· Child Tax Credit: The nonrefundable child tax credit increases to $2,200 per child beginning in 2025 and the credit amount is indexed for inflation.
· Estate and gift tax exemption: The increased exemption is made permanent and raised to
$15 million per individual ($30 million for married couples) in 2026, indexed for inflation
SALT deduction cap: The state and local tax (SALT) deduction cap is increased to $40,000 per household and would be phased out for taxpayers with modified adjusted gross income (MAGI) over
$500,000. In 2030, the deduction will revert to $10,000.
· Charitable deduction for non-itemizers: An above-the-line deduction is added for charitable contributions that starts in 2026 ($1,000 for single filers, $2,000 for joint filers).
· No tax on tips and overtime: For 2025–2028, above-the-line deductions are created for qualified tips (in certain occupations) and for overtime premium pay, subject to income and occupation limitations.
· Enhanced deduction for seniors: For 2025–2028, a $6,000 deduction is available for seniors (age 65+) with income below $75,000 ($150,000 for joint filers).
· Car loan interest deduction: For 2025–2028, up to $10,000 of interest on loans for U.S.- assembled passenger vehicles may be deducted, subject to income phaseouts.
· Moving expense deduction: The deduction is permanently terminated except for those in the Armed Forces.
· Home mortgage interest and insurance premiums: The $750,000 limit on the treatment of mortgage insurance premiums as qualified residence interest is made permanent. The exclusion of home-equity indebtedness from the definition of qualified residence interest is also now permanent.
· Casualty loss deduction for personal casualties: The limitation on personal casualty loss deductions is made permanent, however a provision is added to include state-declared disasters.
· Other deductions and credits: Several other deductions and credits, including the adoption credit, employer-provided childcare credit, paid family and medical leave credit, and education-related benefits are made permanent.
Business tax provisions
· QBI deduction: The qualified business income (QBI) deduction is made permanent and the deductible amount for each qualified business would remain at 20%.
· Bonus depreciation: 100% expensing (bonus depreciation) for qualified property is restored for property placed in service after Jan. 19, 2025.
· Sec. 179 expensing: The maximum amount a business may expense for qualifying expenses is increased to $2.5 million, with the phaseout threshold raised to $4 million, both indexed for inflation after 2025.
Very truly yours,
