New Tax Law Brings Big Wins for Business Owners

Written by Tyler von Lange | Jul 17, 2025 8:15:33 PM

The newly signed tax legislation — also known as the One Big Beautiful Bill Act — brings about significant changes for businesses.

From enhanced bonus depreciation and expanded Section 179 expensing, to updates on research and development costs, business credits and opportunity zones, the legislation is designed to spur investment and simplify planning.

Here’s a breakdown of the key tax updates and what they could mean for your business.

100% §168 Special Bonus Depreciation and §179 Expensing

Business owners will be very happy about these changes.

The legislation allows businesses to take 100% bonus depreciation on applicable assets put into service on or after January 19, 2025. This provision is permanent, and the allowable bonus percentage will not decrease in future years. This is a major increase from the previous law, which allowed only 40% bonus depreciation for assets placed into service in 2025.

Additionally, companies can expense $2.5 million in qualifying assets put into service in the current tax period, indexed for inflation for future tax years, under Section 179. The amount of expense allowed will be reduced if the amount of total qualifying assets put into service exceeds $4 million. This just about doubles the allowable amount that can be expensed under the previous law.

§199A Qualified Business Income Deduction

The current deduction of 20% of qualified business income remains and the deduction becomes permanent. The phase-out range of the deduction was also increased. The bill also provides a minimum $400 deduction for taxpayers with at least $1,000 qualified business income.

Research & Development Expenses

The bill allows companies to immediately expense domestic research and development costs for tax years beginning after December 31, 2024. Under the previous law, companies were required to amortize these costs over a five-year period. The law does not change the treatment of foreign research and development costs, which are required to be amortized over a 15-year period.

Small businesses (under the gross average gross receipts tests) will be allowed to retroactively make this change to prior periods beginning after December 31, 2021. All businesses will be allowed to accelerate the remaining amount of unamortized research and development costs from periods beginning after December 31, 2021 and before January 1, 2025 over a one- or two-year period.

Business Interest Limitation Under §163(j)

The calculation for limiting interest expense deductions no longer uses depreciation, amortization or depletion to reduce the limitation. This change allows businesses that take advantage of depreciation, amortization or depletion to potentially have a lower interest expense limitation, thereby decreasing their taxable income.

Qualified Small Business Stock Exemption Changes

The bill increases the exemption from the gain on the sale of Qualified Small Business Stock under §1202 to $15 million per issuing corporation, up from $10 million. The bill also increases the gross asset threshold for issuing qualifying small business stock to $75 million from $50 million. The full exemption is allowed if the stock is held for five years; the bill increases the amount of gain exempt if it is held for four years from 50% to 75%.

Note: Qualified Small Business Stock can only be issued by a C corporation.

For Manufacturers: 100% §168 Special Depreciation Allowance for Qualified Production Property

The legislation also expands the definition of assets defined as “qualified production property,” which are allowed the 100% special depreciation deduction under §168. Qualified production property is defined generally as nonresidential real property used in manufacturing. This will allow manufacturers to expense real property that was generally depreciated over 39 years previously.

This property must meet the following criteria under amended §168 to be considered “Qualified Production Property”:

  • Used by the taxpayer as an integral part of a qualified production activity
  • Placed in service in the United States or any possession of the United States
  • Original use commences with the taxpayer (not used)
  • Construction of property begins after January 19, 2025, and before January 1, 2029
  • Designated by the taxpayer in an election
  • Placed into service before January 1, 2031

For Manufacturers: Advanced Manufacturing Investment Credit

The bill increases the advanced manufacturing investment credit to 35%, up from 25% since it was first implemented by the CHIPS Act of 2022. This is effective for property that is placed into service after December 31, 2025.

Eligible property must meet the following criteria:

  • Tangible property used in the manufacturing of semiconductors or semiconductor manufacturing equipment
  • Includes buildings and structural components that are integral to the manufacturing process
  • Original use commences with the taxpayer
  • Located in the United States
  • Depreciable asset

Opportunity Zones

Opportunity zones have been permanently renewed. The legislation redefines the definition of opportunity zones, which may affect how future zones are designated. The new rules will go into effect on January 1, 2027.

Corporate Charitable Deduction Limitation

The bill adds a 1% floor on charitable deductions made by C corporations. This means that C corporations will reduce their allowable charitable deductions by 1% of their taxable income. This change is effective for tax years beginning after December 31, 2025. 

For example, if a C corporation has $100,000 in taxable income and $2,000 in charitable deductions, the floor that the corporation can deduct the charitable deductions is $1,000. This means the corporation can only deduct $1,000 instead of the full $2,000. Contributions limited by the 1% floor are not carried forward to future periods.

Form 1099-NEC Reporting Threshold

The bill updates the long-held threshold for reporting a Form 1099-NEC for independent contractors to $2,000, up from $600. The $2,000 threshold will be indexed for inflation.

New Markets Tax Credit

The bill permanently increases the new markets tax credit. The new markets credit is a federal credit that is designed to catalyze private investment in economically distressed communities in the U.S.

Paid Family and Medical Leave Credit

The bill permanently increases the paid family and medical leave credit. This credit is provided to employers who pay family or medical leave to employees that meet eligible criteria, up to two weeks per employee. The credit is between 12.5-25% of wages paid during the period of leave.

Employer-Provided Child Care Credit

The bill increases the employer-provided childcare credit from 25% to 40% (50% for qualifying small businesses) of qualified childcare expenses. The bill also increases the maximum amount of the credit allowed to $500,000 ($600,000 for qualifying small businesses), up from $150,000 under previous law.

Changes In Clean Energy Incentives

The bill repeals numerous clean energy credits and tax incentives after the following dates:

  • September 30, 2025 termination date
    • Previously owned clean energy credit
    • Clean vehicle credit
    • Qualified commercial clean vehicle credit
    • Sustainable aviation fuel credit
  • December 31, 2025 termination date
    • Energy-efficient home improvement credit
    • Residential clean energy credit
  • June 30, 2026 termination date
    • Alternative fuel vehicle refueling credit
    • New energy-efficient home credit
    • Energy-efficient commercial buildings deduction (as long as the construction of the property begins before the termination date)
  • September 30, 2026 termination date
    • Sustainable aviation fuel credit
  • Jan 1, 2028 termination date
    • Clean hydrogen production credit
