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.
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 FAQs also provided clarification on the energy efficient home improvement credit, the residential clean energy credit, among others.
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.
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.
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.
Stock options have become a common part of many compensation and benefits packages. Even small businesses have jumped on the bandwagon and now provide a perk previously confined to the executive suites of large publicly held companies. If you are an employee who has received stock options, you need to be aware of the complicated tax rules that govern certain stock options -- several potential "gotchas" exist and failing to spot them can cause major tax headaches.
Stock options have become a common part of many compensation and benefits packages. Even small businesses have jumped on the bandwagon and now provide a perk previously confined to the executive suites of large publicly held companies. If you are an employee who has received stock options, you need to be aware of the complicated tax rules that govern certain stock options -- several potential "gotchas" exist and failing to spot them can cause major tax headaches.
Over the past few years, the rules governing stock options have become increasingly complicated. More than ever, it is important that employees who receive stock options have a good understanding about how they are taxed -- on receipt of the option, at its exercise, or pursuant to the sale of the underlying stock -- as well as the potential consequences of their decisions regarding the timing of the taxation of those options.
NSOs vs ISOs
The most common type of stock option that employees receive is called a nonstatutory stock option (NSO). The other, less common type of stock option is generically referred to as an incentive stock option (ISO). ISOs are governed by very specific rules and are subjected to strict statutory requirements; NSOs, on the other hand, are subject to more general rules and guidelines.
Incentive stock options (ISOs) give the employee the right to purchase stock from the employer at a specified price. The employee is not taxed on the ISO at the time of its grant or at the time of the exercise of the option. Instead, he or she is taxed only at the time of the disposition of the stock acquired through exercise of the option. Note, however, the exercise of an ISO does give rise to an alternative minimum tax item in the amount of the difference between the option price and the market price of the stock.
Note. The IRS temporarily suspended the collection of ISO alternative minimum tax (AMT) liabilities through September 30, 2008.
NSOs also give the employee the right to purchase stock from the employer at a specified price. When and how an NSO is taxed depends on several factors including whether the underlying stock is substantially vested, and whether or not the fair market value of the stock is readily ascertainable.
Vesting. If an employee receives options from his employer, the tax consequences depend on whether the stock is vested. Stock you receive from your employer is "substantially vested" if it is either "transferable" by the employee or it is no longer subject to a "substantial risk of forfeiture". Property is "transferable" if you can sell, assign or pledge your interest in the option without the risk of losing it. A "substantial risk of forfeiture" exists if the rights in the property transferred depend on the future performance (or refraining from performance) of substantial services by any person, or the occurrence of a certain condition related to the transfer.
Readily ascertainable fair market value. An NSO always has a readily ascertainable fair market value when the option is publicly traded. When an option is not publicly traded, it can have a readily ascertainable fair market value if its value can be measured with reasonable accuracy. IRS rules spell out when fair market value can be measured with reasonable accuracy.
Generally, an employee who receives an NSO that has a readily ascertainable fair market value is subject to special tax rules under the Internal Revenue Code that apply to property received by a taxpayer in exchange for services when the option is granted. Under these rules, the option must be included in the employee's income as ordinary income in the amount of the fair market value in the year the option becomes substantially vested. If the employee paid for the option, he recognizes the value of the option minus its cost. The employee is not taxed again when he exercises the option and buys the corporate stock; he is taxed when the stock is sold. The gain or loss recognized when the employee sells the stock is capital in nature.
No readily ascertainable fair market value. Employees who receive NSOs from privately held companies are most likely to receive an NSO without a readily ascertainable fair market value. In general, when an NSO does not have a readily ascertainable fair market value, taxation occurs at the time when the option is exercised or transferred. The employee will recognize ordinary income in the amount of the value of the stock when it becomes substantially vested minus any amounts paid for the option or stock. The gain or loss recognized when the employee sells the stock is capital in nature. However, employees who have NSOs without a readily ascertainable fair market value also have the ability to elect to have the transaction taxed differently,
Section 83(b) election: Elector beware
Employees who exercise options that did not have a readily ascertainable fair market value when they were granted may elect to report income from the stock underlying the option at the time of the exercise rather than waiting until the stock is substantially vested. This election is referred to as a "Section 83(b) election" and is non-revocable. Once the election is made, any later subsequent appreciation when the stock becomes substantially vested would not be includible in income.
As you can see, the rules and tax laws related to stock options are indeed complicated and require some advance planning in order to avoid a big tax "gotcha". If you are contemplating entering into any transactions that involve stock options, please contact the office for additional guidance.
Keeping the family business in the family upon the death or retirement of the business owner is not as easy as one would think. In fact, almost 30% of all family businesses never successfully pass to the next generation. What many business owners do not know is that many problems can be avoided by developing a sound business succession plan in advance.
Keeping the family business in the family upon the death or retirement of the business owner is not as easy as one would think. In fact, almost 30% of all family businesses never successfully pass to the next generation. What many business owners do not know is that many problems can be avoided by developing a sound business succession plan in advance.
In the event of a business owner's demise or retirement, the absence of a good business succession plan can endanger the financial stability of his business as well as the financial security of his family. With no plan to follow, many families are forced to scramble to outsiders to provide capital and acquire management expertise.
Here are some ideas to consider when you decided to begin the process of developing your business' succession plan:
Start today. Succession planning for the family-owned business is particularly difficult because not only does the founder have to address his own mortality, but he must also address issues that are specific to the family-owned business such as sibling rivalry, marital situations, and other family interactions. For these and other reasons, succession planning is easy to put off. But do you and your family a favor by starting the process as soon as possible to ensure a smooth, stress-free transition from one generation to the next.
Look at succession as a process. In the ideal situation, management succession would not take place at any one time in response to an event such as the death, disability or retirement of the founder, but would be a gradual process implemented over several years. Successful succession planning should include the planning, selection and preparation of the next generation of managers; a transition in management responsibility; gradual decrease in the role of the previous managers; and finally discontinuation of any input by the previous managers.
Choose needs over desires. Your foremost consideration should be the needs of the business rather than the desires of family members. Determine what the goals of the business are and what individual has the leadership skills and drive to reach them. Consider bringing in competent outside advisors and/or mediators to resolve any conflicts that may arise as a result of the business decisions you must make.
Be honest. Be honest in your appraisal of each family member's strengths and weaknesses. Whomever you choose as your successor (or part of the next management team), it is critical that a plan is developed early enough so these individuals can benefit from your (and the existing management team's) experience and knowledge.
Other considerations
A business succession plan should not only address management succession, but transfer of ownership and estate planning issues as well. Buy-sell agreements, stock gifting, trusts, and wills all have their place in the succession process and should be discussed with your professional advisors for integration into the plan.
Developing a sound business succession plan is a big step towards ensuring that your successful family-owned business doesn't become just another statistic. Please contact the office for more information and a consultation regarding how you should proceed with your business' succession plan.
As you open the doors of your new business, the last thing on your mind may be the potential for loss of profits through employee oversight or theft - especially if you are the only employee. However, setting up some basic internal controls to guard against future loss before you hire others can save you headaches in the future.
As you open the doors of your new business, the last thing on your mind may be the potential for loss of profits through employee oversight or theft - especially if you are the only employee. However, setting up some basic internal controls to guard against future loss before you hire others can save you headaches in the future.
Soon after you start making money and the world realizes that they cannot live without your goods or service, you will probably need to hire employees. Although necessary for your growing company, hiring employees increases your risk of loss through errors, oversights and theft.
Implementing internal controls to help you monitor your business can decrease the need for constant supervision of your employees. Internal controls are checks and balances to prevent fraud, limit financial losses and reduce errors or oversights by employees. For example, the most basic internal control concept requires that certain tasks be handled by different people. This process, called "separation of duties", can greatly decrease the probability of loss.
The following basic internal control checklist includes suggestions that, once implemented, can help you and your employees avoid concerns about fraud or theft in the workplace:
Have one person open the mail and list all the checks on the deposit slip while another enters cash receipts in your financial records. Make sure someone who does not handle the checkbook or purchasing is in charge of payments to suppliers and vendors. Have your bank reconciliation done by someone who does not have access to daily checkbook transactions. Make sure that you approve all vendors and that you count all goods received. Check all orders to make sure they are correct and of the quality you intended. Sign each check and review the invoice, delivery receipt and purchase order.As your company grows, you may want to become less and less involved with the day-to-day operations of the business. The internal controls you put into place now will help keep the profits up, the losses down, and help you sleep better at night. If you need any assistance with setting up internal controls for you business, please feel free to contact our office.
The United States is currently experiencing the largest influx of inpatriates (foreign nationals working in the U.S.) in history. As the laws regarding United States taxation of foreign nationals can be quite complex, this article will answer the most commonly asked questions that an inpatriate may have concerning his/her U.S. tax liability and filing requirements.
The United States is currently experiencing the largest influx of inpatriates (foreign nationals working in the U.S.) in history. As the laws regarding United States taxation of foreign nationals can be quite complex, this article will answer the most commonly asked questions that an inpatriate may have concerning his/her U.S. tax liability and filing requirements.
I am a foreign national working in the United States and am paid by my foreign employer. Do I need to file a tax return and pay income taxes?
The general rule is that all wages earned while working in the United States, regardless of who pays for it or the locations of the employer, is taxable in the United States. This is true whether you are treated as a U.S. resident or not.
What is the difference in taxation of a resident alien versus a nonresident alien?
The difference in being taxed as a resident versus a nonresident is as follows: a resident alien is taxable in the U.S. on all worldwide income, regardless of what country it is earned or located in. A nonresident alien is generally taxable only on what is referred to as "effectively connected income". This is normally wages earned while in the U.S., along with earnings on property located in the United States. Certain deductions, exemptions, and filing statuses are not available to nonresidents.
I am not a resident for immigration purposes as I am here on a temporary visa. Can I still be a resident for U.S. tax purposes?
The determination of residency for tax purposes does not bear any relationship to your legal or immigration status. It is quite common for a foreign national to be a nonresident for legal or immigration purposes and yet be a resident for tax purposes. In addition, being a resident for income tax purposes can be different than being a resident for estate tax or even social security tax purposes. In some cases, it is actually more beneficial to be treated as a resident than as a nonresident. As a result, it is important to have all of the information we request in order to make the best decision for you.
How do you determine whether you are a resident or nonresident for U.S. income tax purposes?
As a foreign national working in the U.S., you must first determine if you are a "resident" for U.S. income tax purposes. There are two tests to determine whether you are a U.S. tax resident. These two tests are:
The lawful permanent residence test
The substantial presence test.
If you meet the requirements of either of these two tests, you will be treated as a U.S. tax resident (unless a treaty overrides this).
What is the difference between a lawful permanent resident and meeting the substantial presence test?
Lawful Permanent Resident Test - In its simplest form, this is when you have been issued a green card or alien registration card allowing for permanent residency.
Substantial Presence Test - This is a more complicated test that looks at the number of days of physical presence in the U.S. over a three-year period of time. If the number of days of U.S. presence exceeds 183 days in the current year, or 183 equivalent days during a three-year period, you are a resident for U.S. tax purposes. An "equivalent day" is defined as:
In the current year, each partial day counts as one full equivalent day
In the first preceding year, each day counts as 1/3 of an equivalent day
In the second preceding year, each day counts as 1/6 of an equivalent day.
There are exceptions to the counting of days, but in general, any part of a day counts as a full day.
What if I meet the substantial presence test? Are there exceptions to allow me to be a nonresident anyway?
31 Day Exception - If you are present in the States for less than 31 days in the current year, the substantial presence test is not applied.
Closer Connections Exception - If you are present in the U.S. for fewer than 183 days in the current year AND you maintain a "tax home" in another country during the entire year AND you maintain a closer connection to the foreign country in which you have a tax home, then this test will not apply.
J-1 Visa - Subject to some limitations, you do not count days in the U.S., for calculating the substantial presence test, while you are here on a J-1 visa (generally for up to two years). This does not exempt the earnings, but just allows you to be treated as a nonresident alien, not a resident alien.
Treaty - Some countries have treaties with the U.S. which, in some cases, will override either the U.S. Internal Revenue Code or the income tax law of the foreign country.
If I become a U.S. taxable resident during the year, when does my residency begin?
In general, residency begins on the first physically present day in the U.S. during the year you meet the substantial presence test. There are exceptions for "nominal" days along with the closer connection exception, which can apply here. Remember that residency determines from what point you are taxable on your worldwide income, not when you are taxable.
Likewise, your residency is deemed to end on the last day that you are present in the U.S. within the year that you move from the United States. Problems can arise if you return back to the U.S. within a short period of time.
Can I elect to be treated as a taxable resident even if I do not meet any of the tests (in order to take advantage of special tax rates and laws not available to nonresidents)?
First Year Election - Sometimes it can be better to be treated as a resident than as a nonresident. There is an election available that allows a foreign national to be taxed as a resident in the initial year of a U.S. assignment even if one of the residency tests is not met for the year. To qualify, you would have to satisfy the following:
Must have been a U.S. nonresident in the year immediately preceding the initial year.
You must satisfy the substantial presence test in the year following the initial year.
You must be present in the U.S. for at least 31 consecutive days in the initial year.
During the initial year, you must be present in the U.S. for at least 75% of the days from the start of your 31 consecutive day period through the end of that year.
What if my home country considers me as a taxable resident at the same time the U.S. treats me as a taxable resident? Am I double taxed?
The general rules discussed above are based on the IRS Code. The United States has entered into numerous tax treaties with other countries. The purpose of these treaties is to prevent double taxation issues that may arise due to differences in the tax laws of the two countries. It is possible to be considered a resident, subject to tax in both countries. The treaties usually provide for 'tiebreaker' rules to override the IRS Code or the foreign home country tax laws. Most treaty provisions require the filing of certain documents, though, in order to take benefit of them.
I am on a short-term assignment from my home country and my employer pays for my rent and meals while I am working here in the U.S. Is any of this taxable?
The first thing you need to do is determine whether your assignment is considered "short-term" within the definition of U.S. law. An individual is treated as being on a short-term assignment in the U.S. if their tax home has not changed from their foreign location. If the intent of the assignment is to return to the original work location within one year, the assignment is considered a temporary assignment. This does not determine whether you are a resident or not. It just determines which types of payments are taxable.
The advantage of a temporary assignment is that the employer-provided benefits such as lodging, meals travel and certain other expenses are not considered taxable wages in the U.S. In this case, a resident or nonresident would not be taxed on these payments. On a long-term assignment (more than 12 months), these are typically taxed in addition to the wages.
What happens if I am a nonresident for part of the year and a resident for another part of the year?
It is possible to be taxed in one year as both a resident and a nonresident. If this is the case, a special filing is made on a single tax return, with certain forms required. During the residency period, you would be taxed on worldwide income. During the nonresidency period, you would be taxed only on effectively connected income (usually wages earned in the U.S., as noted earlier).
Can I be exempt or excluded from tax from the U.S. federal government but still be taxed by one of the States?
Yes. Please note quite a few of the 50 states of the U.S. do not follow some, or all, of the U.S. federal tax codes or recognize the Treaties between the U.S. and other countries. So, it is possible, and highly probable, you could be taxable for State purposes but may be exempt for federal. In addition, other tax filing requirements, including estate and gift taxes, social security taxes, along with other filing forms, may be required regardless of your income tax residency determination.
