The Financial Crimes Enforcement Network (FinCEN) has removed the requirement that U.S. companies and U.S. persons must report beneficial ownership information (BOI) to FinCEN under the Corporate Transparency Act.

The Financial Crimes Enforcement Network (FinCEN) has removed the requirement that U.S. companies and U.S. persons must report beneficial ownership information (BOI) to FinCEN under the Corporate Transparency Act. This interim final rule is consistent with the Treasury Department's recent announcement that it was suspending enforcement of the CTA against U.S. citizens, domestic reporting companies, and their beneficial owners, and that it would be narrowing the scope of the BOI reporting rule so that it applies only to foreign reporting companies.

The interim final rule amends the BOI regulations by:

• changing the definition of "reporting company" to mean only those entities that are formed under the law of a foreign country and that have registered to do business in any U.S. State or Tribal jurisdiction by filing of a document with a secretary of state or similar office (these entities had formerly been called "foreign reporting companies"), and
• exempting entities previously known as "domestic reporting companies" from BOI reporting requirements.

Under the revised rules, all entities created in the United States (including those previously called "domestic reporting companies") and their beneficial owners are exempt from the BOI reporting requirement, including the requirement to update or correct BOI previously reported to FinCEN. Foreign entities that meet the new definition of "reporting company" and do not qualify for a reporting exemption must report their BOI to FinCEN, but are not required to report any U.S. persons as beneficial owners. U.S. persons are not required to report BOI with respect to any such foreign entity for which they are a beneficial owner.

Reducing Regulatory Burden

On January 31, 2025, President Trump issued Executive Order 14192, which announced an administration policy "to significantly reduce the private expenditures required to comply with Federal regulations to secure America’s economic prosperity and national security and the highest possible quality of life for each citizen" and "to alleviate unnecessary regulatory burdens" on the American people.

Consistent with the executive order and with exemptive authority provided in the CTA, the Treasury Secretary (in concurrence with the Attorney General and the Homeland Security Secretary) determined that BOI reporting by domestic reporting companies and their beneficial owners "would not serve the public interest" and "would not be highly useful in national security, intelligence, and law enforcement agency efforts to detect, prevent, or prosecute money laundering, the financing of terrorism, proliferation finance, serious tax fraud, or other crimes."The preamble to the interim final rule notes that the Treasury Secretary has considered existing alternative information sources to mitigate risks. For example, under the U.S. anti-money laundering/countering the financing of terrorism regime, covered financial institutions still have a continuing requirement to collect a legal entity customer's BOI at the time of account opening (see 31 CFR 1010.230). This will serve to mitigate certain illicit finance risks associated with exempting domestic reporting companies from BOI reporting.

BOI reporting by foreign reporting companies is still required, because such companies present heightened national security and illicit finance risks and different concerns about regulatory burdens. Further, the preamble points out that the policy direction to minimize regulatory burdens on the American people can still be achieved by exempting foreign reporting companies from having to report the BOI of any U.S. persons who are beneficial owners of such companies.

Deadlines Extended for Foreign Companies

When the interim final rule is published in the Federal Register, the following reporting deadlines apply:

• Foreign entities that are registered to do business in the United States before the publication date of the interim final rule must file BOI reports no later than 30 days from that date.
• Foreign entities that are registered to do business in the United States on or after the publication date of the interim final rule have 30 calendar days to file an initial BOI report after receiving notice that their registration is effective.

Effective Date; Comments Requested

The interim final rule is effective on the date of its publication in the Federal Register.

FinCEN has requested comments on the interim final rule. In light of those comments, FinCEN intends to issue a final rule later in 2025.

Written comments must be received on or before the date that is 60 days after publication of the interim final rule in the Federal Register.

Melanie Krause, the IRS’s Chief Operating Officer, has been named acting IRS Commissioner following the retirement of Doug O’Donnell. Treasury Secretary Scott Bessent acknowledged O’Donnell’s 38 years of service, commending his leadership and dedication to taxpayers. O’Donnell, who had been acting Commissioner since January, will retire on Friday, expressing confidence in Krause’s ability to guide the agency through tax season. Krause, who joined the IRS in 2021 as Chief Data & Analytics Officer, has since played a key role in modernizing operations and overseeing core agency functions. With experience in federal oversight and operational strategy, Krause previously worked at the Government Accountability Office and the Department of Veterans Affairs Office of Inspector General. She became Chief Operating Officer in 2024, managing finance, security, and procurement. Holding advanced degrees from the University of Wisconsin-Madison, Krause will lead the IRS until a permanent Commissioner is appointed.

A grant disbursement to a corporation to be used for rent payments following the September 11, 2001 terrorist attacks on the World Trade Center was not excluded from the corporation's gross income. Grants were made to affected businesses with funding provided by the U.S. Department of Housing and Urban Development. The corporation's grant agreement required the corporation to employ a certain number of people in New York City, with a portion of those people employed in lower Manhattan for a period of time. Pursuant to this agreement, the corporation requested a disbursement as reimbursement for rent expenses.

A grant disbursement to a corporation to be used for rent payments following the September 11, 2001 terrorist attacks on the World Trade Center was not excluded from the corporation's gross income. Grants were made to affected businesses with funding provided by the U.S. Department of Housing and Urban Development. The corporation's grant agreement required the corporation to employ a certain number of people in New York City, with a portion of those people employed in lower Manhattan for a period of time. Pursuant to this agreement, the corporation requested a disbursement as reimbursement for rent expenses.

Exclusions from Gross Income

Under the expansive definition of gross income, the grant proceeds were income unless specifically excluded. Payments are only excluded under Code Sec. 118(a) when a transferor intends to make a contribution to the permanent working capital of a corporation. The grant amount was not connected to capital improvements nor restricted for use in the acquisition of capital assets. The transferor intended to reimburse the corporation for rent expenses and not to make a capital contribution. As a result, the grant was intended to supplement income and defray current operating costs, and not to build up the corporation's working capital.

The grant proceeds were also not a gift under Code Sec. 102(a). The motive for providing the grant was not detached and disinterested generosity, but rather a long-term commitment from the company to create and maintain jobs. In addition, a review of the funding legislation and associated legislative history did not show that Congress possessed the requisite donative intent to consider the grant a gift. The program was intended to support the redevelopment of the area after the terrorist attacks. Finally, the grant was not excluded as a qualified disaster relief payment under Code Sec. 139(a) because that provision is only applicable to individuals.

Accuracy-Related Penalty

Because the corporation relied on Supreme Court decisions, statutory language, and regulations, there was substantial authority for its position that the grant proceeds were excluded from income. As a result, the accuracy-related penalty was not imposed.

CF Headquarters Corporation, 164 TC No. 5, Dec. 62,627

The parent corporation of two tiers of controlled foreign corporations (CFCs) with a domestic partnership interposed between the two tiers was not entitled to deemed paid foreign tax credits under Code Sec. 902 or Code Sec. 960 for taxes paid or accrued by the lower-tier CFCs owned by the domestic partnership. Code Sec. 902 did not apply because there was no dividend distribution. Code Sec. 960 did not apply because the Code Sec. 951(a) inclusions with respect to the lower-tier CFCs were not taken into account by the domestic corporation.

The parent corporation of two tiers of controlled foreign corporations (CFCs) with a domestic partnership interposed between the two tiers was not entitled to deemed paid foreign tax credits under Code Sec. 902 or Code Sec. 960 for taxes paid or accrued by the lower-tier CFCs owned by the domestic partnership. Code Sec. 902 did not apply because there was no dividend distribution. Code Sec. 960 did not apply because the Code Sec. 951(a) inclusions with respect to the lower-tier CFCs were not taken into account by the domestic corporation.

Background

The parent corporation owned three CFCs, which were upper-tier CFC partners in a domestic partnership. The domestic partnership was the sole U.S. shareholder of several lower-tier CFCs.

The parent corporation claimed that it was entitled to deemed paid foreign tax credits on taxes paid by the lower-tier CFCs on earnings and profits, which generated Code Sec. 951 inclusions for subpart F income and Code Sec. 956 amounts. The amounts increased the earnings and profits of the upper-tier CFC partners.

Deemed Paid Foreign Tax Credits Did Not Apply

Before 2018, Code Sec. 902 allowed deemed paid foreign tax credit for domestic corporations that owned 10 percent or more of the voting stock of a foreign corporation from which it received dividends, and for taxes paid by another group member, provided certain requirements were met.

The IRS argued that no dividends were paid and so the foreign income taxes paid by the lower-tier CFCs could not be deemed paid by the entities in the higher tiers.

The taxpayer agreed that Code Sec. 902 alone would not provide a credit, but argued that through Code Sec. 960, Code Sec. 951 inclusions carried deemed dividends up through a chain of ownership. Under Code Sec. 960(a), if a domestic corporation has a Code Sec. 951(a) inclusion with respect to the earnings and profits of a member of its qualified group, Code Sec. 902 applied as if the amount were included as a dividend paid by the foreign corporation.

In this case, the domestic corporation had no Code Sec. 951 inclusions with respect to the amounts generated by the lower-tier CFCs. Rather, the domestic partnerships had the inclusions. The upper- tier CFC partners, which were foreign corporations, included their share of the inclusions in gross income. Therefore, the hopscotch provision in which a domestic corporation with a Code Sec. 951 inclusion attributable to earnings and profits of an indirectly held CFC may claim deemed paid foreign tax credits based on a hypothetical dividend from the indirectly held CFC to the domestic corporation did not apply.

An appeals court affirmed that payments made by an individual taxpayer to his ex-wife did not meet the statutory criteria for deductible alimony. The taxpayer claimed said payments were deductible alimony on his federal tax returns.

The taxpayer’s payments were not deductible alimony because the governing divorce instruments contained multiple clear, explicit and express directions to that effect. The former couple’s settlement agreement stated an equitable division of marital property that was non-taxable to either party. The agreement had a separate clause obligating the taxpayer to pay a taxable sum as periodic alimony each month. The term “divorce or separation instrument” included both divorce and the written instruments incident to such decree.

For 2021, the Social Security tax wage cap will be $142,800, and Social Security and Supplemental Security Income (SSI) benefits will increase by 1.3 percent. These changes reflect cost-of-living adjustments to account for inflation.

For 2021, the Social Security tax wage cap will be $142,800, and Social Security and Supplemental Security Income (SSI) benefits will increase by 1.3 percent. These changes reflect cost-of-living adjustments to account for inflation.

2021 Wage Cap
The Federal Insurance Contributions Act (FICA) tax on wages is 7.65 percent each for the employee and the employer. FICA tax has two components:

• a 6.2 percent Social Security tax, also known as Old Age, Survivors, And Disability Insurance (OASDI); and
• a 1.45 percent Medicare tax, also known as hospital insurance (HI).

For self-employed workers, the Self-Employment tax is 15.3 percent, consisting of:

• a 12.4 percent OASDI tax; and
• a 2.9 percent HI tax.

OASDI tax applies only up to a wage base, which includes most wages and self-employment income up to the annual wage cap.

For 2021, the wage base is $142,800. Thus, OASDI tax applies only to the taxpayer’s first $142,800 in wages or net earnings from self-employment. Taxpayers do not pay any OASDI tax on earnings that exceed $142,800.

There is no wage cap for HI tax.

Maximum Social Security Tax for 2021
For workers who earn $142,800 or more in 2021:

• an employee will pay a total of $8,853.60 in social security tax ($142,800 x 6.2 percent);
• the employer will pay the same amount; and
• a self-employed worker will pay a total of $17,707.20 in social security tax ($142,800 x 12.4 percent).

Additional Medicare Tax
Higher-income workers may have to pay an Additional Medicare tax of 0.9 percent. This tax applies to wages and self-employment income that exceed:

• $250,000 for married taxpayers who file a joint return;
• $125,000 for married taxpayers who file separate returns; and
• $200,000 for other taxpayers.

The annual wage cap does not affect the Additional Medicare tax.

Benefits Increase for 2021
Finally, a cost-of-living adjustment (COLA) will increase social security and SSI benefits for 2019 by 1.3 percent. The COLA is intended to ensure that inflation does not erode the purchasing power of these benefits.

The IRS has adopted previously issued proposed regulations ( REG-106808-19) dealing with the 100 percent bonus depreciation deduction. In addition, some clarifying changes have been made to previously issued final regulations ( T.D. 9874). Changes to the proposed and earlier final regulations are largely in response to various comments submitted by practitioners, and generally relate to:

The IRS has adopted previously issued proposed regulations ( REG-106808-19) dealing with the 100 percent bonus depreciation deduction. In addition, some clarifying changes have been made to previously issued final regulations ( T.D. 9874). Changes to the proposed and earlier final regulations are largely in response to various comments submitted by practitioners, and generally relate to:

• the definition of qualified used property;
• the election to claim bonus depreciation on components acquired or self-constructed after September 27, 2017, for larger self-constructed property for which manufacture, construction, or production began before September 28, 2017;
• application of the mid-quarter convention;
• clarifications to the definition of qualified improvement property, predecessor, and class of property; and
• clarifications to the rules for consolidated groups
  The rules for consolidated groups have also been moved from Proposed Reg. §1.168(k)-2(b)(3)(v) to new Reg. §1.1502-68.

Used Property
The 2019 final regulations provide that in determining whether the taxpayer or a predecessor had a depreciation interest in property prior to its acquisition, only the five calendar years immediately prior to the current placed-in-service year are considered. The latest IRS regulations clarify that the five calendar years immediately prior to the current calendar year in which the property is placed in service by the taxpayer, and the portion of such current calendar year before the placed-in-service date of the property without taking into account the applicable convention, are taken into account. In addition, the five-year look-back period applies separately to the taxpayer and a predecessor.

Furthermore, if the taxpayer or a predecessor, or both, have not been in existence during the entire look-back period, then only the portion of the look-back period during which the taxpayer or a predecessor, or both, have been in existence is taken into account.

Expanded Component Election
The prior regulations allow taxpayers to election to claim 100 percent bonus depreciation on components of certain larger constructed property that qualifies for bonus depreciation if the construction of the larger property began before September 28, 2017. The components must be acquired or constructed after September 27, 2017, and the larger property must be placed in service before 2020 (2021 in the case of property with a longer construction period). The final regulations remove the 2020/2021 cutoff date. In addition, the final regulations provide that eligible larger self-constructed property also includes property that is constructed for a taxpayer under a written contract that is not binding and that is entered into prior to construction for use in the taxpayer’s trade or business. The definition of a larger constructed property is also clarified.

Qualified Improvement Property
The 15-year recovery period for qualified improvement property applies only to improvements "made by the taxpayer." The final regulations clarify that an improvement is considered made by a taxpayer if the property is constructed for the taxpayer. However, qualified improvement property received by a transferee taxpayer in a nonrecognition transaction described in Code Sec. 168(i)(7) is not eligible for bonus depreciation.

Mid-Quarter Convention
The final regulations clarify that depreciable basis is not reduced by the amount of bonus deduction in determining whether the mid-quarter convention applies.

Binding Contracts
Generally, property acquired pursuant to a binding contract entered into after September 27, 2017, does not qualify for bonus depreciation at the 100 percent rate. The final regulations clarify that a contract for a sale of stock of a corporation that is treated as an asset sale as the result of a Code Sec. 336(e) election made for a disposition described in Reg. §1.336-2(b)(1) is a binding contract if enforceable under state law.

Floor Plan Financing
The IRS intends to issue guidance relating to transition relief for taxpayers with a trade or business with floor plan financing indebtedness that want to revoke elections not to claim bonus depreciation for property placed in service during 2018.

The IRS will not allow a taxpayer to limit the amount of its otherwise deductible floor plan interest in order to qualify for bonus depreciation. However, guidance will address transition relief for the 2018 tax year for taxpayers that treated Code Sec. 168(j)(1) as providing an option for a business with floor plan financing indebtedness to include or exclude its floor plan financing interest expense in determining the amount allowed as a deduction for business interest expense for the tax year.

Effective Date
In general, the regulations apply to property acquired after September 27, 2017, and placed in service during or after a tax years that begins on or after January 1, 2021. However, they may be relied on for earlier tax years.

Final regulations reflect the significant changes that the Tax Cuts and Jobs Act (TCJA) ( P.L. 115-97) made to the Code Sec. 274 deduction for travel and entertainment expenses. These regulations finalize, with some changes, previously released proposed regulations, NPRM REG-100814-19.

Final regulations reflect the significant changes that the Tax Cuts and Jobs Act (TCJA) ( P.L. 115-97) made to the Code Sec. 274 deduction for travel and entertainment expenses. These regulations finalize, with some changes, previously released proposed regulations, NPRM REG-100814-19.

Changes to Code Sec. 274 under the TCJA
For most expenses paid or incurred after 2017, TCJA:

• repealed the "directly related to a trade or business" and the business-discussion exceptions to the general disallowance of entertainment expense deductions;
• eliminated the general business expense deduction for 50 percent of entertainment (but not meal) expenses; and
• repealed the special substantiation rules for deductible entertainment (but not travel) expenses. Taxpayers may rely on the proposed regulations until they are finalized.

Entertainment Expenses
Among other things, Reg. §1.274-11:

• restates the statutory rules of Code Sec. 274(a), including the entertainment deduction disallowance rule for dues or fees to any social, athletic, or sporting club or organization;
• substantially incorporates the existing definition of "entertainment" from Reg. §1.274-2(b)(1); and
• confirms that the nine exceptions in Code Sec. 274(e) continue to apply to deductible entertainment expenditures.

The regulations also confirm that "entertainment" does not include food or beverages unless they are provided at or during an entertainment activity, and their costs are included in the entertainment costs.

Food and Beverage Expenses
As under the proposed regulations, Reg. §1.274-12 allows taxpayers to deduct 50 percent of business meal expenses if:

• the expense is an ordinary and necessary business expense;
• the expense is not lavish or extravagant; the taxpayer or an employee is present when the food or beverage is furnished;
• the food or beverage is provided to a current or potential business customer, client, consultant, or similar business contact; and
• food and beverages that are provided during or at an entertainment activity are purchased separately from the entertainment, or their cost is separately stated.

With respect to the fourth requirement listed above, the final regulations adopt the definition of "business associate" in Reg. §1.274-2(b)(2)(iii), but expands it to include employees. Thus, these requirements would apply to employer-provided meals to employees as well as non-employees. The final regulations also flesh out the fifth requirement listed above, and clarify that the separate charges for entertainment-related food and beverages must reflect their actual cost, including delivery fees, tips, and sales tax. Indirect expenses such as transportation to the food are not included in the actual cost.

Exceptions and Special Rules
Food or beverage expenses for employer-provided meals at an eating facility do not include expenses for the operation of the facility, such as salaries of employees preparing and serving meals, and other overhead costs. The final regulations apply the TCJA changes to the exceptions and special rules for deductible food and beverages in Code Sec. 274(e), Code Sec. 274(k) and Code Sec. 274(n), including:

• reimbursed food or beverage expenses;
• recreational expenses for employees;
• items available to the public; and
• goods or services sold to customers.

The final regulations also provide examples on several specific scenarios to illustrate the rules.

The IRS has issued a final regulation addressing tax withholding on certain periodic retirement and annuity payments under Code Sec. 3405(a), to implement amendments made by the Tax Cuts and Jobs Act ( P.L. 115-97) (TCJA). The regulation affects payors of certain periodic payments, plan administrators that are required to withhold on such payments, and payees who receive such payments. The final regulation adopts, without modification, a proposed regulation that updated and replaced the provisions of three questions and answers with a new regulation regarding the default withholding rate on periodic payments made after December 31, 2020.

The final regulation adopts, without modification, a proposed regulation that updated and replaced the provisions of three questions and answers with a new regulation regarding the default withholding rate on periodic payments made after December 31, 2020.

Withholding on Periodic Payments
Before the TCJA, if a withholding certificate (Form W-4P) was not in effect for a periodic payment, the default withholding rate on the payment was determined by treating the payee as a married individual claiming three withholding exemptions. The TCJA amended Code Sec. 3405(a)(4) so that the default withholding rate on such a periodic payment is instead determined under rules prescribed by the Treasury Secretary.

After the TCJA was enacted, the IRS issued three notices providing that, for calendar years 2018, 2019, and 2020, the default withholding rate on periodic payments under Code Sec. 3405(a)(4) is based on treating the payee as a married individual claiming three withholding allowances ( Notice 2020-3, I.R.B. 2020-3, 330; Notice 2018-92, I.R.B. 2018-51, 1038; Notice 2018-14, I.R.B. 2018-7, 353).

Under new Reg. §31.3405(a)-1, the default rate of withholding on periodic payments made after December 31, 2020, is determined in the manner described in the applicable forms, instructions, publications, and other guidance prescribed by the IRS.

Applicability Date
The final regulation applies to periodic payments made after December 31, 2020.

The IRS has issued final regulations that provide guidance for employers on federal income tax withholding from employees’ wages.

The IRS has issued final regulations that provide guidance for employers on federal income tax withholding from employees’ wages. The final regulations:

• address the amount of federal income tax that employers withhold from employees’ wages;
• implement changes made by the Tax Cuts and Jobs Act (TCJA) ( P.L. 115-97); and
• reflect the redesigned Form W-4, Employee’s Withholding Certificate, and related IRS publications.

TCJA Changes
The TCJA made many amendments affecting income tax withholding on employees’ wages. The TCJA made many amendments affecting income tax withholding on employees’ wages.After the TCJA was enacted, the IRS issued guidance to implement the changes (for example, Notice 2018-14, I.R.B. 2018-7, 353; Notice 2018-92, I.R.B. 2018-51, 1038; Notice 2020-3, I.R.B. 2020-3, I.R.B. 2020-3, 330). The IRS updated Form W-4 and its instructions with significant changes intended to improve the accuracy of income tax withholding and make the withholding system more transparent for employees. It also released IRS Publication 15-T, Federal Income Tax Withholding Methods, which provides percentage method tables, wage bracket withholding tables, and other computational procedures for employers to use to compute withholding for the 2020 calendar year.

On February 13, 2020, the IRS published a notice of proposed rulemaking ( REG-132741-17) to update the regulations under Code Sec. 3401 and Code Sec. 3402 to reflect the legislative changes, and expand the rules to accommodate changes necessary to fully implement the redesigned Form W-4 and its related computational procedures, along with most existing computational procedures that apply to 2019 or earlier Forms W-4.

The final regulations adopt the proposed regulations with a few revisions.

Form W-4
The final regulations do not require all employees with a 2019 or earlier Form W-4 in effect to furnish a redesigned Form W-4. Comments expressed concerns that the proposed regulations and the related forms, instructions, publications, and other IRS guidance would require employers to maintain two different systems for computing income tax withholding on wages: one for 2019 or earlier Forms W-4, and another for the redesigned Forms W-4.

In response, the IRS is acknowledging concerns with (1) instructions to the redesigned Form W-4 for employees with multiple jobs and (2) optional computational “bridge” entries permitted under the regulations and described in Publication 15-T that will allow employers to continue in effect 2019 or earlier Forms W-4 as if the employees had furnished redesigned Forms W-4.

The final regulations revise Reg. §31.3402(f)(4)-1(a) to provide that an employer’s use of the computational bridge entries to adapt a 2019 or earlier Form W-4 to the redesigned computational procedures as if using entries on a redesigned Form W-4 will continue in effect such a Form W-4 that was properly in effect on or before December 31, 2019.

Lock-in Letters
The IRS issues a "lock-in" letter to notify an employer that an employee is not entitled to claim exemption from withholding, or is not entitled to the withholding allowance claimed on the employee’s Form W-4. The lock-in letter prescribes the withholding allowance the employer must use to figure withholding. After the lock-in letter becomes effective, the IRS may issue a subsequent modification notice, but only after the employee contacts the IRS to request an adjustment to the withholding prescribed in the lock-in letter.

Under the final regulations, employers are not required to notify the IRS that they no longer employ an employee for whom a lock-in letter was issued. Further, the final regulations do not require the IRS to reissue lock-in letters or modification notices solely because of the redesigned Form W-4.

The final regulations revise Reg. §31.3402(f)(2)-1(g)(2)(iv) relating to lock-in letters. and Reg. §31.3402(f)(2)-1(g)(2)(vii) relating to modification notices, to provide that an employer may comply with a lock-in letter or modification notice that is based on a 2019 or earlier Form W-4, as required by the regulations, if the employer implements the maximum withholding allowance and filing status permitted in a lock-in letter or modification notice by using the computational bridge entries as set forth in forms, instructions, publications, and other IRS guidance to calculate withholding for such a Form W-4.

Estimated Tax Payments
The final regulations revise Reg. §31.3402(m)-1(d) to allow employees to take estimated tax payments into account, as long as the employee (1) follows the instructions to the IRS’s Tax Withholding Estimator (available at https://www.irs.gov/individuals/tax-withholding-estimator) or IRS Publication 505, (2) is not subject to a lock-in letter or modification notice, and (3) does not request withholding from wages that falls below the pro rata share of income taxes attributable to wages determined under forms, instructions, publications, and other IRS guidance. The IRS intends to update its Tax Withholding Estimator and Publication 505 to reflect this rule.

Applicable Date
The final regulations generally apply on the date they are published in the Federal Register. Reg. §31.3402(f)(2)-1(g), regarding withholding compliance, applies as of February 13, 2020. Reg. §31.3402(f)(5)-1(a)(3), regarding the requirement to use the current version of Form W-4, applies as of March 16, 2020. The removal of Reg. §31.3402(h)(4)-1(b), regarding the combined income tax withholding and employee FICA tax withholding tables, applies on and after January 1, 2020.

Except for the removal of Reg. §31.3402(h)(4)-1(b), taxpayers may choose to apply the final regulations on and after January 1, 2020, and before their applicability date set forth in the regulations.
