The IRS has announced that, under the phased implementation of the One Big Beautiful Bill Act (OBBBA), there will be no changes to individual information returns or federal income tax withholding tables for the tax year at issue. Specifically, Form W-2, existing Forms 1099, Form 941 and other payroll return forms will remain unchanged for 2025. Employers and payroll providers are instructed to continue using current reporting and withholding procedures. This decision is intended to avoid disruptions during the upcoming filing season and to give the IRS, businesses and tax professionals sufficient time to implement OBBBA-related changes effectively.

In addition to this, IRS is developing new guidance and updated forms, including changes to the reporting of tips and overtime pay for TY 2026. The IRS will coordinate closely with stakeholders to ensure a smooth transition. Additional information will be issued to help individual taxpayers and reporting entities claim benefits under OBBBA when filing returns.

The IRS issued frequently asked questions (FAQs) relating to several energy credits and deductions that are expiring under the One, Big, Beautiful Bill Act (OBBB) and their termination dates. The FAQs also provided clarification on the energy efficient home improvement credit, the residential clean energy credit, among others.

Energy Efficient Home Improvement Credit

The credit will not be allowed for any property placed in service after December 31, 2025.

Residential Clean Energy Credit

The credit will not be allowed for any expenditures made after December 31, 2025. Due to the accelerated termination of the Code Sec. 25C credit, periodic written reports, including reporting for property placed in service before January 1, 2026, are no longer required.

A manufacturer is still required to register with the IRS to become a qualified manufacturer for its specified property to be eligible for the credit.

Clean Vehicle Program

New user registration for the Clean Vehicle Credit program through the Energy Credits Online portal will close on September 30, 2025. The portal will remain open beyond September 30, 2025, for limited usage by previously registered users to submit time-of-sale reports and updates to such reports.

Acquiring Date

A vehicle is “acquired” as of the date a written binding contract is entered into and a payment has been made. Acquisition alone does not immediately entitle a taxpayer to a credit. If a taxpayer acquires a vehicle and makes a payment on or before September 30, 2025, the taxpayer will be entitled to claim the credit when they place the vehicle in service, even if the vehicle is placed in service after September 30, 2025.

IR-2025-86

The IRS has provided guidance regarding what is considered “beginning of constructions” for purposes of the termination of the Code Sec. 45Y clean electricity production credit and the Code Sec. 48E clean electricity investment credit. The One Big Beautiful Bill (OBBB) Act (P.L. 119-21) terminated the Code Secs. 45Y and 48E credits for applicable wind and solar facilities placed in service after December 31, 2027.

The IRS has provided guidance regarding what is considered “beginning of constructions” for purposes of the termination of the Code Sec. 45Y clean electricity production credit and the Code Sec. 48E clean electricity investment credit. The One Big Beautiful Bill (OBBB) Act (P.L. 119-21) terminated the Code Secs. 45Y and 48E credits for applicable wind and solar facilities placed in service after December 31, 2027. The termination applies to facilities the construction of which begins after July 4, 2026. On July 7, 2025, the president issue Executive Order 14315, Ending Market Distorting Subsidies for Unreliable, Foreign-Controlled Energy Sources, 90 F.R. 30821, which directed the Treasury Department to take actions necessary to enforce these termination provisions within 45 days of enactment of the OBBB Act.

Physical Work Test

In order to begin construction, taxpayers must satisfy a “Physical Work Test,” which requires the performance of physical work of a significant nature. This is a fact based test that focuses on the nature of the work, not the cost. The notice addresses both on-site and off-site activities. It also provides specific lists of activities that are to be considered work of a physical nature for both solar and wind facilities. Preliminary activities or work that is either in existing inventory or is normally held in inventory are not considered physical work of a significant nature.

Continuity Requirement

The Physical Work Test also requires that a taxpayer maintain a continuous program of construction on the applicable wind or solar facility, the Continuity Requirement. To satisfy the Continuity Requirement, the taxpayer must maintain a continuous program of construction, meaning continuous physical work of a significant nature. However, the notice provides a list of allowable “excusable disruptions,” including delays related to permitting, weather, and acquiring equipment, among others.

The guidance also provides a safe harbor for the Continuity Requirement. Under the safe harbor, the Continuity Requirement will be met if a taxpayer places an applicable wind or solar facility in service by the end of a calendar year that is no more than four calendar years after the calendar year during which construction of the applicable wind or solar facility began. Thus, if construction begins on an applicable wind or solar facility on October 1, 2025, the applicable wind or solar facility must be placed in service before January 1, 2030, for the safe harbor to apply.

Five Percent Safe Harbor for Low Output Solar Facilities

A safe harbor is available for a low output solar facility, which is defined as an applicable solar facility that has maximum net output of not greater than 1.5 megawatt. A low output solar facility may also establish that construction has begun before July 5, 2026, by satisfying the Five Percent Safe Harbor (as described in section 2.02(2)(ii) of Notice 2022-61).

Additional Guidance

The notice provides additional guidance regarding: construction produced for the taxpayer by another party under a binding written contract; the definition of a qualified facility; the definition of property integral to the applicable wind or solar facility; the application of the 80/20 rule to retrofitted applicable wind or solar facilities under Reg. §§ 1.45Y-4(d) and 1.48E-4(c); and the transfer of an applicable wind or solar facility.

Effective Date

Notice 2025-42 is effective for applicable wind and solar facilities for which the construction begins after September 1, 2025.

Notice 2025-42

The Treasury Inspector General for Tax Administration suggested the way the Internal Revenue Service reports level of service (ability to reach an operator when requested) and wait times does not necessarily reflect the actual times taxpayers are waiting to reach a representative at the agency.

The Treasury Inspector General for Tax Administration suggested the way the Internal Revenue Service reports level of service (ability to reach an operator when requested) and wait times does not necessarily reflect the actual times taxpayers are waiting to reach a representative at the agency.

"For the 2024 Filing Season, the IRS reported an LOS of 88 percent and wait times averaging 3 minutes," TIGTA stated in an August 14, 2025, report. "However, the reported LOS and average wait times only included calls made to 33 Accounts Management (AM) telephone lines during the filing season."

TIGTA stated that the agency separately tracks Enterprise LOS, a broader measure of of the taxpayer experience which includes 27 telephone lines from other IRS business units in addition to the 33 AM telephone lines.

"The IRS does not widely report an Enterprise-wide wait time- as the reported average wait time computation includes only the 33 AM telephone lines," the report states. "According to IRS data, the average wait times for the other telephone lines were much longer than 3 minutes, averaging 17 to 19 minutes during the 2024 Filing Season."

TIGTA recommended that the IRS adjust its reporting to include Enterprise LOS in addition to AM LOS and provide averages across all telephone lines.

"The IRS disagreed with both recommendations stating that the LOS metric does not provide information to determine taxpayer experience when calling, and including wait times for telephone lines outside the main helpline would be confusing to the public," the Treasury watchdog reported. "We maintain that whether a taxpayer can reach an assistor is part of the taxpayer experience and providing average wait times across all telephone lines for the entire fiscal year demonstrates transparency."

The Treasury watchdog also noted that the National Taxpayer Advocate has stated the AM LOS is "materially misleading" and should be replaced as a benchmark.

TIGTA also warned that the reduction in workforce at the IRS could hurt recent improvements to LOS and wait times, noting that the agency will lose about 23 percent of its customer service representative employees by the end of September 2025.

"The staffing impact on the remainder of Calendar Year 2025 and the 2026 Filing Season are unknown, but we will be monitoring these issues."

It also noted that the IRS is working on a new metric – First Call/Contact Resolution – to measure the percentage of calls that resolve the customer’s issue without a need to transfer, escalate, pause, or return the customer’s initial phone call. TIGTA reported that analysis of FY 2024 data revealed that 33 percent of taxpayer calls were transferred unresolved at least once.

The Financial Crimes Enforcement Network (FinCEN) has granted exemptive relief to covered investment advisers from the requirements the final regulations in FinCEN Final Rule RIN 1506-AB58 (also called the "IA AML Rule"), which were set to become effective January 1, 2026. This order exempts covered investment advisers from all requirements of these regulations until January 1, 2028.

The Financial Crimes Enforcement Network (FinCEN) has granted exemptive relief to covered investment advisers from the requirements the final regulations in FinCEN Final Rule RIN 1506-AB58 (also called the "IA AML Rule"), which were set to become effective January 1, 2026. This order exempts covered investment advisers from all requirements of these regulations until January 1, 2028.

The regulations require investment advisers (defined in 31 CFR §1010.100(nnn)) to establish minimum standards for anti-money laundering/countering the financing of terrorism (AML/CFT) programs, report suspicious activity to FinCEN, and keep relevant records, among other requirements.

FinCEN has determined that the regulations should be reviewed to ensure that they strike an appropriate balance between cost and benefit. The review will allow FinCEN to ensure the regulations are consistent with the Trump administration's deregulatory agenda and are effectively tailored to the investment adviser sector's diverse business models and risk profiles, while still adequately protecting the U.S. financial system and guarding against money laundering, terrorist financing, and other illicit finance risks. Covered investment advisers are exempt from the obligations of the regulations while the review takes place.

FinCEN intends to issue a notice of proposed rulemaking (NPRM) to propose a new effective date for these regulations no earlier than January 1, 2028.

This exemptive relief is effective from August 5, 2025, until January 1, 2028.

FinCEN Exemptive Relief Order

Move over hybrids - buyers of Volkswagen and Mercedes diesel vehicles now qualify for the valuable alternative motor vehicle tax credit. Previously, the credit had gone only to hybrid vehicles. Now, the IRS has qualified certain VW and Mercedes diesels as "clean" as a hybrid.

Qualifying vehicles

The IRS has designated the following diesel-powered vehicles as advanced lean-burning technology motor vehicles that qualify for the alternative motor vehicle tax credit:

• The 2009 VW Jetta TDI sedan and TDI sportwagen models; and
• The 2009 Mercedes-Benz GL320, R320 and ML320 Bluetec models.

 The credit amounts vary depending on the vehicle's fuel economy. The credit amounts for each vehicle are as follows:

• 2009 VW Jetta TDI sedan and TDI sportwagen: $1,300 credit;
• 2009 Mercedes ML320 Bluetec: $900;
• 2009 Mercedes R320 Bluetec: $1,550; and
• 2009 GL320 Bluetec: $1,800.

VW's diesels went on sale in August, while the Mercedes Bluetec models are expected to go on sale beginning this October.

The alternative motor vehicle tax credit, generally

The alternative motor vehicle tax credit is a lucrative tax credit for purchasers of qualifying automobiles. But, just as the situation is with hybrids, the full amount of the credit for each vehicle is available only during a limited period. The dollar value of the tax credit will begin to be reduced once the manufacturer sells 60,000 vehicles that qualify for the tax credit. Additionally, the credit is available only to the original purchaser of a new, qualifying vehicle. As such individuals who lease the vehicle are not eligible for the credit - the credit is allowed only to the vehicle's owner, such as the leasing company.

Taxpayers may claim the full amount of the allowable credit up to the end of the first calendar quarter after the quarter in which the manufacturer records its sale of the 60,000th advance lean burn technology motor vehicle or hybrid passenger automobile or light truck. For the second and third calendar quarters after the quarter in which the 60,000th vehicle is sold, taxpayers may claim 50 percent of the credit. For the fourth and fifth calendar quarters, taxpayers may claim 25 percent of the credit. No credit is allowed after the fifth quarter.

The credit - as Congress has allotted so far - may only be taken for qualified vehicles purchased before the end of 2010.
