What the One Big Beautiful Bill Means for Your 2025 Taxes

The One Big Beautiful Bill introduces several major tax updates beginning in 2025, including new deductions, adjustments to retirement savings rules, credit enhancements, and revised income thresholds. The following highlights the most relevant changes for taxpayers and small businesses.

Beginning in 2025, taxpayers who receive voluntary tips may deduct up to $25,000 of qualified tip income each year, even if they take the standard deduction. This deduction applies to both employees and self-employed individuals who work in tipping-based occupations.

Tip: If you or your staff receive significant tip income, SK Financial CPA can help you plan and report efficiently.

Several additional deductions will also be available beginning in 2025. These deductions apply whether a taxpayer itemizes or not and will be reported on a new Schedule 1-A (Additional Deductions).

• Overtime Pay Deduction: Up to $12,500 (single) or $25,000 (joint)

• Senior Deduction: Additional $6,000 per taxpayer age 65+ (or $12,000 if both spouses are age 65+)

• New Automobile Loan Interest Deduction: Up to $10,000 of interest on qualifying new vehicles purchased between 2025 and 2028

These deductions phase out at higher income levels based on modified adjusted gross income.

The IRS has confirmed new contribution limits along with future Roth requirements.

• 401(k) limit: $23,500

• Age 50+ catch-up: + $7,500

• Enhanced Super Catch-Up (ages 60–63): Up to $34,750

• SIMPLE IRA limit: $16,500 with expanded catch-up allowances

• Beginning in 2026, individuals earning over $145,000 in the prior year will be required to make catch-up contributions to a Roth (after-tax) account

• Employers must update plan documents by December 31, 2026

These values will apply to the 2026 tax year (filed in 2027):

• Standard Deduction:

  • $32,200 Married Filing Jointly

  • $16,100 Single

  • $24,150 Head of Household

• Estate Tax Exclusion: $15 million

• Expanded Employer Childcare Credit up to $500,000+

• Higher limits for Earned Income Credit, transportation benefits, and employee health spending accounts

Taxpayers may deduct interest on qualifying new personal vehicle loans originated between January 1, 2025, and December 31, 2028. Lenders will receive penalty relief for simplified reporting in 2025, with full reporting enforcement beginning in 2026.

• Up to $5,000 of the adoption credit becomes refundable

• Tribal governments are now recognized in determining special-needs adoption status

• Families adopting eligible special-needs children may claim the full credit (projected $17,280 in 2025) even if they do not have documented adoption expenses

The IRS must update tax forms, processing systems, and guidance to support these changes. Due to workforce reductions and recent operational disruptions, taxpayers may see longer processing times, delayed response cycles, and potential impacts on future filing season timelines.

The IRS is encouraging more taxpayers to settle disputes without going to court through its Alternative Dispute Resolution (ADR) programs. A new pilot, Post Appeals Mediation (PAM), allows taxpayers who have completed the appeals process but still have unresolved issues to request a final one-day mediation session with a neutral IRS mediator.

The IRS confirms that certain Medicaid difficulty-of-care payments to in-home caregivers are generally not taxable when the caregiver and recipient live in the same household. FICA taxes may still apply if there is an employer-employee relationship, but are typically not required when the caregiver is the spouse or parent of the individual receiving care.

The Supreme Court is considering whether homeowners are entitled to receive surplus proceeds when a property is sold in a tax foreclosure. Some states currently allow governments to keep the full sale amount, even after the tax debt is covered. 

Clients owning real estate, including rental properties, primary homes, or inherited property should be aware of these developments, as they may impact equity rights in future tax enforcement situations. SK Financial CPA will continue monitoring the ruling and advise affected clients once guidance is issued.

• 2026 per diem rates are set at $319/day in high-cost areas and $225/day elsewhere; meals-only rates are $86 and $74.

• Self-employed individuals may use the meals rate but must keep lodging receipts.

• The IRS is refining the 15% minimum corporate tax and easing rules on tax-free spin-offs.

• Full expensing for U.S. R&D costs is restored, with small businesses (under $31M) allowed to apply it retroactively to 2022.

• 3M won a transfer pricing case involving international royalty payments.
