As the 2025 tax season approaches, taxpayers across the U.S. are preparing to tackle a host of transformative changes brought about by the One Big Beautiful Bill Act (OBBBA). This comprehensive legislation introduces sweeping reforms that will significantly affect tax returns for individuals, families, and small business owners alike. Whether it's adjustments to child tax credits or new deductions, the OBBBA is designed to make tax preparation more advantageous for typical Americans. In this article, we'll delve into the critical provisions of the OBBBA and other crucial updates, providing the guidance needed to navigate these changes effectively and ensure taxpayers are ready for the upcoming tax season. Our aim is to help you maximize deductions, file accurately, and on time by staying informed—a key asset when collaborating with tax preparers or accountants.
Before diving into the many alterations impacting 2025, it's essential to understand Adjusted Gross Income (AGI) as it plays a pivotal role in numerous new tax provisions. AGI is a fundamental figure in the U.S. tax system, indicating a taxpayer's total income for the year after accounting for specific deductions, such as retirement contributions or student loan interest. It serves as a baseline for defining taxable income and eligibility for various tax credits and deductions. Modified Adjusted Gross Income (MAGI) extends the AGI by adding back certain deductions and exclusions, like foreign income or tax-exempt interest, depending on the specific tax provision. MAGI often determines eligibility for income-limited benefits or credits, making it a broader metric than AGI. When a tax provision phases out, the benefits lessen as income exceeds a certain threshold, ultimately disappearing beyond a higher income level, a strategy that ensures tax benefits are directed towards lower-income individuals.
The following are significant changes effective in 2025, some permanent and others temporary.
Senior Deduction: From 2025 through 2028, seniors 65 or older can each claim a $6,000 deduction. It phases out for singles with a MAGI over $75,000 and for married couples filing jointly over $150,000, reducing by $100 for each $1,000 exceeding these thresholds. Both itemizers and standard deduction filers are eligible.

No Tax on Tips: From 2025 through 2028, a deduction up to $25,000 per year is allowed for qualified cash tips in customary tip-receiving occupations, excluding specific service trades. For occupation details, refer to IR-2025-92. The deduction phases out when AGI surpasses $150,000 for singles and $300,000 for joint filers, reducing by $100 per $1,000 over. This deduction applies per return and is available to both itemizers and standard deduction filers. Employers will reflect qualifying tips on W-2s, but during 2025’s transition, employers may issue a separate statement to report tips.
No Tax on Qualified Overtime: Similar to the tips exemption, this allows a deduction up to $12,500 ($25,000 for MFJ) for overtime pay above the regular rate. It phases out for MAGI over $150,000 (singles) and $300,000 (joint), reducing by $100 for every $1,000 over.
Vehicle Loan Interest Deduction: From 2025 through 2028, individuals can deduct up to $10,000 annually on interest for loans secured by new passenger vehicles assembled in the U.S. Phases out between $100,000-$150,000 for singles and $200,000-$250,000 for joint filers, available to both itemizers and standard deduction filers.

Adoption Credit: The OBBBA introduces a $17,280 credit, with $5,000 refundable, for 2025. It's phased out between $259,190 and $299,190, applicable across all filing types, with a five-year excess carry-forward.
Child Tax Credit: OBBBA elevates the credit to $2,200 ($1,700 refundable) for dependents under 17 from 2025 to 2028. Phases out at $400,000 MAGI for joint filers, $200,000 for others, reducing by $50 per $1,000 above these limits.
Environmental Tax Credits: Early terminations include electric vehicle credits ending after September 30, 2025, and clean energy credits ceasing on December 31, 2025.
SALT Deduction Limit: OBBBA increases the SALT deduction to $40,000, phasing down from $500,000 MAGI to $600,000.
Retirement Plan Catch-Up Contributions: From 2025, individuals 60-63 can contribute $10,000 or 50% more than standard catch-up limits to qualified plans. The 2025 enhanced catch-up is $11,250, except SIMPLE plans at $5,250, inflation-adjusted starting from 2026.
Third Party Network Reporting: OBBBA reverses ARPA's lower reporting thresholds for Form 1099-K, restoring them to $20,000 in gross payments and 200 transactions for 2022 onward.
Section 529 Plans: Effective July 4, 2025, OBBBA expands 529 funds to cover educational expenses across all levels, providing families versatile planning options.
Qualified Small Business Stock (QSBS): For QSBS acquired after July 4, 2025, gain exclusions incrementally increase from 50% to 100% over five years, with increased caps, adjusting post-2026.
Business Expenditure Changes: From 2025, immediate domestic deductions for experimental expenses; foreign expenses continue to be amortized over 15 years.

Business Interest Deduction: Post-2024, interest deductions shift from EBIT to EBITDA calculations; further disadvantageous changes apply post-2025.
Minimum QBI Deduction: Available from 2025, a minimum $400 deduction for at least $1,000 of QBI from actively managed businesses.
Qualified Production Property: Temporary provision allows expensing new nonresidential property for domestic production, effective until 2031.
Section 179 Expensing: With limits increased to $2.5 million for 2025 and inflation adjusted later, these provisions provide upfront tax savings but include potential recapture circumstances.
Bonus Depreciation: 100% bonus depreciation after January 19, 2025, on qualifying assets, incentivizing business investments by accelerating deductions.
