The OB3 Bill Explained: How It Could Affect Different Types of Taxpayers
Every few years, a piece of legislation comes along that changes the rules for nearly everyone who files a tax return. The One Big Beautiful Bill Act, commonly referred to as the OB3 or OBBBA, is one of those moments.
Signed into law on July 4, 2025, the One Big Beautiful Bill makes many of the temporary tax law changes first introduced under the Tax Cuts and Jobs Act of 2017 permanent, while also introducing new provisions that could affect your 2025 return and every return going forward.
But here is the part that matters most from a planning standpoint: this bill does not affect everyone the same way.
Whether you are a salaried employee, a self-employed contractor, a retiree, a parent, or a small business owner, the OB3 touches different parts of your tax picture. Some people will benefit significantly if they take action. Others may be caught off guard if they assume this year’s filing will look the same as last year’s.
The goal of this post is simple: help you identify which taxpayer category you fall into, understand what provisions are most relevant to you, and recognize when it is time to sit down with a CPA before making assumptions about your strategy.
Who Should Read This?
Everyone who files a federal tax return. That said, the sections most relevant to you depend on how you earn money, how your household is structured, and what credits and deductions you have historically relied on. Read through the section that matches your situation most closely, or read them all. Many taxpayers fall into more than one category.
W-2 Employees
If you receive a paycheck with taxes already withheld, the OB3 introduces several provisions worth knowing about.
Standard Deduction: Now Permanent and Higher
The standard deduction received a slight increase starting in 2025. The original 2025 levels rise from $15,000 to $15,750 for single filers, from $22,500 to $23,625 for heads of household, and from $30,000 to $31,500 for joint filers, adjusted for inflation and now made permanent going forward. If you take the standard deduction, this is a direct benefit.
No Tax on Tips
Effective 2025 through 2028, employees may deduct qualified tips received in occupations the IRS has identified as customarily and regularly receiving tips. The maximum annual deduction is $25,000, and it phases out for taxpayers with modified adjusted gross income over $150,000 ($300,000 for joint filers). If you work in a tip-based role in service, hospitality, or delivery, this deduction could meaningfully reduce your taxable income.
No Tax on Overtime
Effective 2025 through 2028, employees who receive qualified overtime compensation may deduct the pay that exceeds their regular rate, such as the “half” portion of time-and-a-half pay required under the FLSA. The maximum annual deduction is $12,500 ($25,000 for joint filers), phasing out for taxpayers with modified adjusted gross income over $150,000 ($300,000 for joint filers).
Auto Loan Interest Deduction
Effective 2025 through 2028, individuals may deduct interest paid on a loan used to purchase a new, personally used vehicle assembled in the United States. The maximum annual deduction is $10,000, and it phases out for taxpayers with modified adjusted gross income over $100,000 ($200,000 for joint filers). Lease payments do not qualify.
What W-2 employees should do: Update your withholding using the IRS Tax Withholding Estimator to account for new deductions. If you earn tips or overtime regularly, make sure you understand the documentation requirements before filing.
Parents and Families
Households with children or dependents have several areas worth reviewing closely. Some provisions are expanded. Others come with new conditions.
Child Tax Credit
The higher value of the Child Tax Credit set by the TCJA is now permanent and slightly increased to $2,200 per child. The amount of the CTC and the related refundable credit of $1,400 will be adjusted for inflation annually. Income phase-outs remain the same at $400,000 for married couples filing jointly and $200,000 for single filers.
529 Plans: Expanded Uses
Changes to 529 savings plans after July 4, 2025, allow families to use tax-free distributions for a much broader range of K-12 expenses, including not just tuition but also curriculum, books, online materials, tutoring, standardized test fees, dual enrollment, and educational therapies for students with disabilities. If you have unused 529 funds, the expanded rules give you more flexibility and reduce the risk of penalties.
Trump Accounts (New Child Investment Accounts)
Starting after July 4, 2025, taxpayers can open a new tax-deferred investment account for U.S. citizen children under age 18. Contributions are capped at $5,000 per year in after-tax dollars, and funds must be invested in a diversified U.S. equity index fund. For children born between January 1, 2025, and December 31, 2028, the federal government will automatically contribute $1,000 to each account.
Adoption Credit
The maximum adoption credit is $17,670 for 2026, and up to $5,120 of this credit may now be refundable, a meaningful change for families pursuing adoption who may not have had enough tax liability to fully utilize the credit in prior years.
Employer-Provided Childcare
For tax year 2026, the maximum employer-provided childcare tax credit increases from $150,000 to $500,000, or $600,000 for eligible small businesses. If your employer offers childcare benefits, or you are a business owner exploring this option, the expanded credit makes it more valuable than before.
What parents should do: Do not assume last year’s tax strategy still applies. The CTC increase, expanded 529 rules, and new savings accounts all represent real opportunities, but they require intentional planning to maximize.
Seniors and Retirees
Retirees have a dedicated provision in this legislation that provides meaningful tax relief, but it comes with income-based limits that make planning important.
New Senior Deduction
Effective 2025 through 2028, individuals age 65 and older may claim an additional deduction of $6,000, separate from and in addition to the existing standard deduction for seniors. For married couples where both spouses qualify, the deduction is $12,000. It phases out for taxpayers with modified adjusted gross income over $75,000 ($150,000 for joint filers), and is available to both itemizing and non-itemizing taxpayers.
For retirees drawing from multiple income sources, including Social Security, required minimum distributions, pension income, and investment distributions, this deduction requires careful income management. Exceeding the MAGI threshold reduces the benefit.
IRA and Retirement Account Planning
For active participants in employer retirement plans, the phaseout for making deductible IRA contributions occurs at AGIs between $79,000 and $89,000 for single and head of household filers, and $126,000 to $146,000 for joint returns. Managing taxable income in retirement is not just about reducing today’s tax bill. It also determines eligibility for provisions like the senior deduction.
What retirees should do: Work with a CPA to model your taxable income across all sources. The $6,000 senior deduction is worth capturing, but it requires keeping MAGI below the phase-out threshold. This is particularly important for retirees who are taking required minimum distributions or managing investment withdrawals.
Freelancers, Self-Employed, and Gig Workers
Independent workers face a more complex filing picture than W-2 employees, and the OB3 has specific implications for this group.
Tips and Overtime Deductions Apply Here Too
Self-employed individuals who receive qualified tips may also deduct them, though the deduction cannot exceed net income from the trade or business where the tips were earned. If you operate in a service industry as a sole proprietor, this is worth reviewing.
1099-K Reporting Threshold Changes
Starting in 2025 and beyond, third-party payment platforms are only required to send you a Form 1099-K if your total payments exceed $20,000 and you received over 200 transactions on any one platform in a given year. However, you are still required to report the income even if you do not receive a form. This is a compliance issue, not a tax break. Not receiving a 1099-K does not mean the income is not taxable.
Estimated Tax Planning
For freelancers and gig workers, the combination of new deductions and changing reporting rules creates both opportunity and risk. New deductions for overtime and tips can reduce your taxable income, but only if you are tracking and documenting them properly throughout the year. Missing quarterly estimated payments based on incorrect income projections can result in penalties.
What freelancers should do: Review your estimated tax payments in light of any new deductions that may apply to you. If your income fluctuates, work with a CPA to model different income scenarios and avoid underpayment penalties, especially now that ACA premium tax credit repayment rules have been tightened under OB3.
Small Business Owners and Founders
The OB3 is arguably most significant for business owners, with several provisions that reward proactive planning.
QBI Deduction: Now Permanent
The 20% Qualified Business Income (QBI) deduction, originally set to expire in 2025, is now made permanent. The new law also increases income limits for taxpayers claiming the QBI deduction, meaning more business owners will qualify. Starting in 2026, a minimum deduction of $400, indexed for inflation, is allowed for any business activity with QBI of $1,000 or more.
This is one of the most impactful changes for pass-through entities including LLCs, S-corps, sole proprietors, and partnerships. With the deduction now permanent, structuring your business to optimize for QBI eligibility is no longer a short-term consideration. It is a long-term planning foundation.
Bonus Depreciation: Restored to 100%
Bonus depreciation is now restored to allow full expensing of qualifying equipment placed in service after January 19, 2025. Businesses can potentially deduct the full cost of equipment in the year it is placed in service, resulting in major upfront tax savings.
Section 179 expensing limits are also increased to $2,500,000, with a phase-down threshold of $4,000,000, both subject to inflation adjustments, for property placed in service after 2024.
R&D Expensing
The OB3 allows immediate expensing of domestic R&D expenditures starting in 2025, with certain small businesses permitted to retroactively apply this provision for tax years beginning after December 31, 2021. If you deferred R&D deductions in prior years, this could represent a meaningful retroactive opportunity worth discussing with your CPA.
1099 Reporting Thresholds
For payments made after 2025, the reporting thresholds for Forms 1099-NEC and 1099-MISC increase from $600 to $2,000, adjusted for inflation after 2026. This reduces administrative burden for businesses making smaller payments to contractors, but does not eliminate reporting obligations entirely.
What business owners should do: This is not the year to file and move on. The QBI deduction, bonus depreciation, and R&D expensing changes all require intentional planning around entity structure, payroll ratios, and asset timing. Proactive strategy here will outperform reactive filing, often significantly.
HSA Users and Healthcare-Focused Taxpayers
If you use a Health Savings Account or rely on healthcare-related tax planning, several OB3 provisions are directly relevant.
HSA Eligibility Expanded
Starting January 1, 2026, bronze and catastrophic health insurance plans are treated as HSA-compatible, whether purchased through an insurance exchange or not. This change makes more people eligible to contribute to an HSA, including individuals who previously could not because their plan did not meet the strict high-deductible health plan definition.
Telehealth and other remote care services can now be received before meeting a high-deductible health plan deductible without affecting HSA eligibility, and this rule is permanent for plan years starting on or after January 1, 2025.
Premium Tax Credit: Repayment Rules Tightened
The OBBBA did not extend enhanced premium tax credits for ACA marketplace plans. The bill also requires marketplace enrollees who receive premium tax credits to repay the full amount if they receive more financial help than they ultimately qualify for, posing a significant burden for people with unpredictable incomes.
For self-employed individuals and gig workers who rely on ACA marketplace plans, this repayment provision is a serious planning issue. Income fluctuations that push you over the eligibility threshold mid-year can result in a large repayment at filing.
What HSA users should do: If you were previously ineligible for an HSA due to your plan type, revisit your eligibility for 2026. If you receive ACA premium tax credits, work closely with a CPA to project your income accurately throughout the year to avoid repayment exposure.
Homeowners and Energy Credit Users
Homeowners who were planning to use energy-related tax credits to offset the cost of upgrades need to act, and act quickly.
Clean Energy Credits Are Being Phased Out
The Energy Efficient Home Improvement Credit (Section 25C) is not allowed for any property placed in service after December 31, 2025. The Residential Clean Energy Credit (Section 25D) is not allowed for any expenditures made after December 31, 2025. The New Clean Vehicle Credit and Used Clean Vehicle Credit are not allowed for any vehicle acquired after September 30, 2025.
If you were planning to install solar panels, purchase an EV, or make energy-efficient home improvements, the window has largely closed.
SALT Deduction: Significantly Expanded
The SALT deduction cap has been raised to $40,000 for incomes under $500,000, with the cap gradually reduced for single taxpayers earning over $250,000 and married taxpayers earning over $500,000. The increased cap and income threshold will increase by 1% annually through 2029.
For homeowners in higher-tax states or municipalities, this change may make itemizing more attractive than taking the standard deduction. It is worth recalculating which approach saves more under your specific situation.
Charitable Contributions for Standard Deduction Filers
Under the OB3, standard deduction filers can now deduct up to $2,000 in cash charitable gifts if married and filing jointly, or up to $1,000 for single or married filing separately taxpayers. This provision begins in the 2026 tax year.
What homeowners should do: If you were holding off on energy-related upgrades hoping to capture credits next year, that strategy no longer applies. On the SALT side, work with your CPA to determine whether itemizing makes sense under the new $40,000 cap.
Higher-Income and Complex Taxpayers
For taxpayers with multiple income streams, investment portfolios, significant deductions, or estate planning needs, the OB3 introduces both opportunities and new constraints.
SALT Phase-Out for Higher Earners
The SALT deduction cap increase phases out above $500,000 in income, reverting toward the $10,000 limit. High earners in states with significant income or property taxes may see less benefit from this change than middle-income homeowners.
Estate and Gift Tax Exemption
The basic exclusion amount for federal estate and gift tax increases to $15 million, indexed for inflation, for estates of decedents dying and gifts made after December 31, 2025, up from approximately $14 million in 2025. For families with significant assets, the expanded exemption creates a planning window, but it requires coordinated action across estate planning, gifting strategy, and entity structure.
Itemized Deduction Limitations
The changes to itemized deductions under the OBBBA are broad in scope, covering nearly all deduction categories on Schedule A. The SALT deduction cap change is the only one taking effect in 2025; the remainder begin in 2026. Taxpayers who itemize should review all relevant categories before assuming their deduction picture stays the same.
Charitable Giving: New Floor for Itemizers
Charitable contributions are now subject to a new 0.5%-of-AGI floor for itemizing taxpayers. If charitable giving is part of your tax strategy, this is a change to discuss with your CPA before year-end.
What complex taxpayers should do: Year-round planning is no longer optional at this income level. It is essential. The interaction between SALT changes, QBI deductions, charitable giving floors, itemized deduction limitations, and estate planning opportunities is too nuanced to address at the point of filing. The earlier you engage a CPA, the more options you have.
The Bottom Line
The OB3 is the most significant overhaul of the federal tax code since 2017. Some provisions are already in effect for your 2025 tax year. Others take effect in 2026. Several come with sunset dates that add a timing element to your planning.
The consistent thread across every taxpayer category is this: what worked last year may not be optimal this year. New deductions need to be claimed correctly. Expiring credits have hard cutoff dates. Phase-outs mean income management matters more than ever.
The smartest move you can make right now is not to wait until April.
Not sure which OB3 changes apply to your situation? Reach out to Robert before making assumptions about your deductions, credits, or filing strategy. A proactive review now is far less costly than an unpleasant surprise at filing time.
