The White House is looking to lower the Internal Revenue Service budget by $1.4 billion in fiscal year 2027.

The White House is looking to lower the Internal Revenue Service budget by $1.4 billion in fiscal year 2027.

The budget request, released April 6, 2026, says the overall budget request for the agency will “streamline IRS operations utilizing technology improvements to help focus the IRS on providing high-quality customer service while ensuring the tax laws are fairly administered.”

The request highlighted two areas where it is currently saving money – ending the Direct File program and reducing staffing by 27 percent total – since January 2025.

The decrease accounts for most of the White House’s overall decreased budget request for the Department of the Treasury. The Trump Administration is an $11.5 billion budget for fiscal year 2027, a 12-percent decrease ($1.5 billion) from the budget enacted for fiscal year 2026.

The Office of the Inspector General would see a $4 million decrease to $44 million from the $48 million level in 2026, while the Treasury Inspector General for Tax Administration would see a decrease from $220 million to $206 million.

The IRS has issued final regulations for the "no tax on tips" deduction under Code Sec. 224, which was enacted as part of the the One Big Beautiful Bill Act (OBBBA) (P.L. 119-21). The final regulations adopt proposed regulations that were issued in September 2025 ( NPRM REG-110032-25), with modifications and clarifications in response to comments received.

The IRS has issued final regulations for the "no tax on tips" deduction under Code Sec. 224, which was enacted as part of the the One Big Beautiful Bill Act (OBBBA) (P.L. 119-21). The final regulations adopt proposed regulations that were issued in September 2025 ( NPRM REG-110032-25), with modifications and clarifications in response to comments received.

Background

Under Code Sec. 224, an eligible individual can claim an income tax deduction for qualified tips received in tax years 2025 through 2028. The deduction is limited to $25,000 per tax year, and starts to phase out when modified adjusted gross income is above $150,000 ($300,000 for joint filers). An employer must report qualified tips on an employee‘s Form W-2, or the employee must report the tips on Form 4137. A service recipient must report qualified tips on an information return furnished to a nonemployee payee (Form 1099-NEC, Form 1099-MISC, Form 1099-K).

A "qualified tip" is a cash tip received in an occupation that customarily and regularly received tips on or before December 31, 2024. An amount is not a qualified tip unless (1) the amount received is paid voluntarily without any consequence for nonpayment, is not the subject of negotiation, and is determined by the payor; (2) the trade or business in which the individual receives the amount is not a specified service trade or business under Code Sec. 199A(d)(2); and (3) other requirements established in regulations or other guidance are satisfied.

The proposed regulations provided eight broad categories of occupations that customarily and regularly received tips on or before December 31, 2024. For each occupation, the list provided a numeric Treasury Tipped Occupation Code (TTOC), an occupation title, a description of the types of services performed in the occupation, illustrative examples of specific occupations, and the related Standard Occupation Classification (SOC) system code(s) published by the Office of Management and Budget (OMB).

List of Occupations that Receive Tips

The final regulations made several modifications to the list of the occupations set forth in the proposed regulations. Three new occupations were added:

• "Visual Artists" and "Floral Designers" were added to the Personal Services category; and
• "Gas Pump Attendants" was added to the Transportation and Delivery category.

The final regulations also made changes and clarifications under several of the occupation categories, including:

• Beverage & Food Service – For the "Wait Staff" occupation, "banquet staff" has been added as an illustrative example, and the occupation's description has been modified to include catered events. The "Food Servers, Non-restaurant" occupation has been changed to "Food and Beverage Servers, Non-restaurant," to clarify that winery tasting room servers are covered by this category.
• Entertainment and Events – The preamble to the final regulations states that "table game supervisors" are covered by the "Gambling Dealers" occupation. The IRS also clarified that individuals dressed up as Santa Claus, as well as other characters or celebrities, are covered by the "Entertainers and Performers" occupation.
• Hospitality and Guest Services – "Doorman" has been added to the list of illustrative examples for the "Baggage Porters and Bellhops" occupation.
• Personal Services – To clarify that resident care is included in the "Personal Care and Service Workers" occupation, the description in the list provides that "work is performed in various settings depending on the needs of the care recipient and may include locations such as their home, place of work, out in the community, at a daytime nonresidential facility or a residential facility." The "Pet Caretakers" occupation has been renamed as the "Pet and Show Animal Caretakers" occupation, and "horse groomer" has been added to the list of illustrative examples.
• Personal Appearance and Wellness – The "Eyebrow Threading and Waxing Technicians" occupation has been renamed as the "Eyebrow and Eyelash Technicians" occupation, and additions were made to the description in the list to include eyelash technicians.
• Recreation and Instruction – The "Travel Guides" occupation now includes a parenthetical noting that both indoor and outdoor locations are covered.
• Transportation and Delivery - "App/platform based delivery person" has been added to the illustrative list in both the "Goods Delivery People" occupation and the "Taxi and Rideshare Drivers and Chauffeurs" occupation. Also, the phrase "over established routes or within an established territory" has been removed from the description of the "Goods Delivery People" occupation.

The final regulations clarify that apprentices and assistants qualify under the applicable TTOC occupation category if they perform the same services as those listed in the TTOC occupation description.

Chiropractors, accountants, tax preparers, concert merchandise sellers, and "low bono" legal service providers were not added to the occupations list, despite requests in the comments to add these to the list.

No occupations included on the occupations list in the proposed regulations were removed from the list in the final regulations.

Voluntary Tips

Regarding the requirement that qualified tips must be voluntary, it is clarified that the customer must have the option to reduce the tip amount to zero. Tip selection methods such as Point-of-Sale (POS) systems with a tip slider that goes to zero or an option for the customer to select "other" and input zero are voluntary. Examples in the final regulations have been modified to clarify that these methods are considered voluntary tipping practices.

Further, the final regulations state that situations where nonpayment of a tip is "without consequence" include situations where nonpayment of the tip does not have any impact on the scope or cost of the service. The final regulations also contain a new example where the tip is part of a contract that is entered into before the services are provided. The example concludes that the tip is a qualified tip because it is paid without consequence. If the customer had chosen to not pay the tip, then the scope or cost of the service would not have been affected.

The final regulations include two new examples to help clarify when payments to digital content creators are tips and when they are compensation. It is also clarified that tipping digital content creators through audience engagement mechanisms that result in superficial digital rewards, such as highlighted messages or other digital tokens of appreciation from the tip recipient that are negligible in value, do not disqualify an otherwise qualified tip.

Other Matters

The final regulations state that amounts received as a tip that are not separately reported to an individual on a statement furnished to the individual pursuant to Code Secs. 6041(d)(3), 6041A(e)(3), 6050W(f)(2), or 6051(a)(18), or reported by the taxpayer on Form 4137 (or successor) are not eligible for the tips deduction. (The preamble recognizes, however, that Notice 2025-69 provides transition rules for this for 2025.)

It is also clarified that "cash tips" include amounts paid in foreign currency. Rules are also provided for tips received by digital tipping systems.

Regarding abuse of the tips deduction, the final regulations replace the provision prohibiting ownership in or employment by a payor with a provision stating that an amount is not a qualified tip, and thus not eligible for the deduction if, based on all relevant facts and circumstances, the amount represents a recharacterization of wages or payments for goods or services for purposes of claiming the deduction.

Effective Date

The final regulations are effective on June 12, 2026, the date that is 60 days after publication in the Federal Register.

The IRS issued updated frequently asked questions (FAQs) addressing educational assistance programs under Code Sec. 127. The FAQs provide general guidance on eligibility, tax treatment of benefits, and recent legislative updates.

The IRS issued updated frequently asked questions (FAQs) addressing educational assistance programs under Code Sec. 127. The FAQs provide general guidance on eligibility, tax treatment of benefits, and recent legislative updates.

General Background

The FAQs explained that a Code Sec. 127 educational assistance program is a written employer plan that provides benefits exclusively to employees. The program must satisfy nondiscrimination requirements that prevent preferential treatment for highly compensated employees, shareholders or owners.

Exclusion Limits and Tax Treatment

The FAQs clarified that employees could exclude up to $5,250 per year in educational assistance benefits for the tax years at issue. The limit applied to combined benefits, including tuition and qualified education loan repayments. Amounts exceeding this limit were taxable and unused amounts could not be carried forward. Expenses covered under Code Sec. 127 could not be used for other credits or deductions.

Eligible and Non-Eligible Benefits

Eligible benefits included tuition, fees, books, supplies, equipment and payments of principal or interest on qualified education loans. These benefits could be provided for undergraduate or graduate courses and did not need to be job-related. However, meals, lodging, transportation and equipment that employees could retain were not eligible. Courses involving hobbies or sports were not eligible unless required for a degree or related to the employer’s business.

Eligibility and Other Provisions

The FAQs emphasized that benefits were limited to employees and included restrictions on owners and shareholders to ensure compliance with nondiscrimination rules. Other provisions, such as working condition fringe benefits, could allow additional exclusions depending on the facts.

The IRS has issued procedures for nominating population census tracts that would be designated as qualified opportunity zones (QOZs). The tracts would designated as QOZs effective on January 1, 2027. The guidance was directed at Chief Executive Officers (CEO) of States, territories of the United States and the District of Columbia. The procedures fell under Reg. §§1400Z-1 and Code Sec. 1400Z-2, as amended by the One, Big, Beautiful Bill Act (OBBBA) (P.L. 119-21).

The guidance was directed at Chief Executive Officers (CEO) of States, territories of the United States and the District of Columbia. The procedures fell under Reg. §§1400Z-1 and Code Sec. 1400Z-2, as amended by the One, Big, Beautiful Bill Act (OBBBA) (P.L. 119-21).

Background

A QOZ is an economically distressed area in which select new investments could be eligible for preferential tax treatment. The OBBBA makes the QOZ tax incentive permanent. The first round of QOZ designations following the enactment of the OBBBA will take effect on January 1, 2027. New rounds would follow every 10 years. Additionally, the OBBBA added tax benefits specific to investments made into QOZs that are comprised entirely of a rural area.

Identities of LICs

The Treasury and IRS identified 25,332 population census tracts that are low-income communities (LIC) eligible for nomination as a 2027 QOZ. Out of said tracts, 8,334 tracts are comprised entirely of a rural area. Beginning July 1, 2026, and lasting a period of 90 days, subject to a single 30-day extension, State CEOs would begin nominating eligible census tracts to be designated as QOZs.

The number of population census tracts in a State that may be designated as QOZs may not exceed 25 percent of the number of LICs in the State. This limitation is determined based on the 2020-2024 American Community Survey (ACS) 5-Year and the 2020 Decennial Census of Island Areas (DECIA) data sets. The tracts were identified using said data sets.

Further, boundaries established for the 2020 decennial census are controlling. They would not be subject to change during the 2027 QOZ designation period.

Nomination Tool

The Treasury has been developing a nomination tool. This would be accessible online and available for the benefit of State CEOs that nominate census tracts for designation as 2027 QOZs.

The QOZ designation period will begin on January 1, 2027, and end on December 31, 2036. Any request to modify such a nomination after October 28, 2026, would be denied. Finally, nominations of tracts not mentioned in this document would be considered, provided they satisfy Code Sec. 1400Z-1(c)(1).

Effective Date

This revenue procedure is effective on April 6, 2026.

IR 2026-45

The IRS has provided a waiver of the addition to tax under Code Sec. 6654 for the underpayment of estimated income tax by qualifying farmers and fishermen.

The IRS has provided a waiver of the addition to tax under Code Sec. 6654 for the underpayment of estimated income tax by qualifying farmers and fishermen. Under Code Sec. 6654(i)(1), a qualifying farmer or fisherman has only one required installment payment (instead of four quarterly payments) due on January 15 of the year following the taxable year if at least two-thirds of the taxpayer’s total gross income was from farming or fishing in either the tax year or the preceding tax year. For a qualifying farmer or fisherman who does not make the required estimated tax installment payment by January 15 of the year following the tax year, Code Sec. 6654(i)(1)(D) provides that the taxpayer is not subject to an addition to tax for failing to pay estimated income tax if the taxpayer files the return for the tax year and pays the full amount of tax reported on the return by March 1 of the year following the tax year.

Difficulty in Electronic Filing of Form 8995

The IRS has noted that some qualifying farmers and fishermen were unable to electronically file Form 8995, Qualified Business Income Deduction Simplified Computation, which was required to be included in their 2025 tax returns. Due to this inability, farmers and fishermen may have had difficulty filing their 2025 tax returns electronically by the March 2, 2026 due date. Accordingly, the IRS has determined to waive certain penalties for qualifying farmers and fishermen due to these unusual circumstances.

Waiver of Underpayment of Estimated Income Tax

The IRS has waived the addition to tax under Code Sec. 6654 for failure to make an estimated tax payment for the 2025 tax year for any qualifying farmer or fisherman who files a 2025 tax return and pays in full any tax due on the return by April 15, 2026. The waiver will apply to any taxpayer who is a qualifying farmer or fisherman for the 2025 tax year and fulfills the conditions stated in the previous sentence. Further, the waiver will apply automatically to any taxpayer who qualifies for the waiver and does not report an addition to tax under Code Sec. 6654 on the 2025 tax return.

In addition, taxpayers who otherwise satisfy the criteria for relief under the IRS’ notice, but have already filed a return and reported an addition to tax, may request an abatement of the addition to tax by filing Form 843, Claim for Refund and Request for Abatement, in accordance with the prescribed instructions.

State and local housing credit agencies that allocate low-income housing tax credits and states and other issuers of tax-exempt private activity bonds have been provided with a listing of the proper population figures.

State and local housing credit agencies that allocate low-income housing tax credits and states and other issuers of tax-exempt private activity bonds have been provided with a listing of the proper population figures to be used when calculating the 2026:

• calendar-year population-based component of the state housing credit ceiling under Code Sec. 42(h)(3)(C)(ii);
• calendar-year private activity bond volume cap under Code Sec. 146; and
• exempt facility bond volume limit under Code Sec. 142(k)(5).

These figures are derived from the estimates of the resident populations of the 50 states, the District of Columbia and Puerto Rico, which were released by the Bureau of the Census on January 27, 2026. The figures for the insular areas of American Samoa, Guam, the Northern Mariana Islands and the U.S. Virgin Islands are the 2025 midyear population figures in the U.S. Census Bureau’s International Database.

Notice 2026-22

Internal Revenue Service CEO Frank Bisignano promoted some of the highlights of the 2026 tax filing season before a congressional committee while deflecting questions about data leaks and other issues.

Internal Revenue Service CEO Frank Bisignano promoted some of the highlights of the 2026 tax filing season before a congressional committee while deflecting questions about data leaks and other issues.

Testifying April 15, 2026, during a Senate Finance Committee hearing, Bisignano used his opening statement to promote the highlights of the tax filing season, including:

• 134 million individual returns filed, with 98 percent filed electronically;
• 80 million refunds issued with 98 percent of funds sent electronically; and
• An average refund of more than $3,400 (up 11 percent from last year), with more than 90 percent received by taxpayers in less than 21 days.

He also stated that 53 million American have taken advantage of new tax breaks found in the One Big Beautiful Bill Act, including the No Tax On Tips (6 million filers), No Tax On Overtime (25 million filers), and No Tax On Car Loan Interest provision (1 million filers), as well as the deduction for seniors (30 million filers).

“When you look at all this, it’s the reason we talk about the historic refunds,” Bisignano testified.

These, along with the increase to the standard deduction and the child tax credit, along with the full expensing for capital investments being made permanent “prevented a tax increase of over $5 trillion on American families and small businesses,” Bisignano testified.

Bisignano defended the decision to end the Direct File program, noting that 2 million Americans have used a free file option, adding that “Direct File was a costly, unnecessary, and less popular duplicate of programs that already are in place.”

He continued: “Despite heavy promotion by the Biden Administration, Direct File was the by far the least used free filing option.”

When faced with questions regarding data breeches, including information given to ICE by Treasury and other data breeches, Bisignano refused to answer, stating that ongoing litigation was preventing him from commenting in the case of the information given to ICE, and that ongoing investigations in other data breeches precluded him from discussing them.

He also refused to express even a general opinion on the lawsuit filed by President Trump on the leaking of his tax information.

When challenged on the tax gap, Bisignano challenged assertions that it more than $1 trillion. Bisignano said the last published number was $650 billion and added that it was “big enough so we don’t have to debate the trillion.” He said the agency was working on a plan to address it but did not offer any specifics as to what the IRS had planned to close the tax gap. He did say the agency has increased the dollar amount of money recovered from compliance activities.

“Collections and enforcement is up 12 percent, and this is year to date,” he testified, adding that more than $2 billion has been collected in the top five audits.

The Taxpayer Advocacy Panel (TAP) has released its 2025 Annual Report. The report highlighted accomplishments and ongoing efforts to (1) strengthen IRS delivery; (2) improve communications with taxpayers; (3) reduce taxpayer burden; and (4) support continued modernization of tax administration. The TAP project committees submitted 20 project referrals to the IRS, including 188 recommendations for improving IRS operations and enhancing taxpayer experience.

The IRS expects to receive more than 150 million individual income tax returns this year and issue billions of dollars in refunds. That huge pool of refunds drives scam artists and criminals to steal taxpayer identities and claim fraudulent refunds. The IRS has many protections in place to discover false returns and refund claims, but taxpayers still need to be proactive.

The IRS expects to receive more than 150 million individual income tax returns this year and issue billions of dollars in refunds. That huge pool of refunds drives scam artists and criminals to steal taxpayer identities and claim fraudulent refunds. The IRS has many protections in place to discover false returns and refund claims, but taxpayers still need to be proactive.

Tax-related identity theft

Tax-related identity theft most often occurs when a criminal uses a stolen Social Security number to file a tax return claiming a fraudulent refund. Often, criminals will claim bogus tax credits or deductions to generate large refunds. Fraud is particularly prevalent for the earned income tax credit, residential energy credits and others. In many cases, the victims of tax-related identity theft only discover the crime when they file their genuine return with the IRS. By this time, all the taxpayer can do is to take steps to prevent a recurrence.

Being proactive

However, there are steps taxpayers can take to reduce the likelihood of being a victim of tax-related identity theft. Personal information must be kept confidential. This includes not only an individual's Social Security number (SSN) but other identification materials, such as bank and other financial account numbers, credit and debit card numbers, and medical and insurance information. Paper documents, including old tax returns if they were filed on paper returns, should be kept in a secure location. Documents that are no longer needed should be shredded.

Online information is especially vulnerable and should be protected by using firewalls, anti-spam/virus software, updating security patches and changing passwords frequently. Identity thieves are very skilled at leveraging whatever information they can find online to create a false tax return.

Impersonators

Criminals do not only steal a taxpayer's identity from documents. Telephone tax scams soared during the 2015 filing season. Indeed, a government watchdog reported that this year was a record high for telephone tax scams. These criminals impersonate IRS officials and threaten legal action unless a taxpayer immediately pays a purported tax debt. These criminals sound convincing when they call and use fake names and bogus IRS identification badge numbers. One sure sign of a telephone tax scam is a demand for payment by prepaid debit card. The IRS never demands payment using a prepaid debit card, nor does the IRS ask for credit or debit card numbers over the phone.

The IRS, the Treasury Inspector General for Tax Administration (TIGTA) and the Federal Tax Commission (FTC) are investigating telephone tax fraud. Individuals who have received these types of calls should alert the IRS, TIGTA or the FTC, even if they have not been victimized.

Tax-related identity theft is a time consuming process for victims so the best defense is a good offense. Please contact our office if you have any questions about tax-related identity theft.

An employer must withhold income taxes from compensation paid to common-law employees (but not from compensation paid to independent contractors). The amount withheld from an employee's wages is determined in part by the number of withholding exemptions and allowances the employee claims. Note that although the Tax Code and regulations distinguish between withholding exemptions and withholding allowances, the terms are interchangeable. The amount of reduction attributable to one withholding allowance is the same as that attributable to one withholding exemption. Form W-4 and most informal IRS publications refer to both as withholding allowances, probably to avoid confusion with the complete exemption from withholding for employees with no tax liability.

An employer must withhold income taxes from compensation paid to common-law employees (but not from compensation paid to independent contractors). The amount withheld from an employee's wages is determined in part by the number of withholding exemptions and allowances the employee claims. Note that although the Tax Code and regulations distinguish between "withholding exemptions" and "withholding allowances," the terms are interchangeable. The amount of reduction attributable to one withholding allowance is the same as that attributable to one withholding exemption. Form W-4 and most informal IRS publications refer to both as withholding allowances, probably to avoid confusion with the complete exemption from withholding for employees with no tax liability.

An employee may change the number of withholding exemptions and/or allowances she claims on Form W-4, Employee's Withholding Allowance Certificate. It is generally advisable for an employee to change his or her withholding so that it matches his or her projected federal tax liability as closely as possible. If an employer overwithholds through Form W-4 instructions, then the employee has essentially provided the IRS with an interest-free loan. If, on the other hand, the employer underwithholds, the employee could be liable for a large income tax bill at the end of the year, as well as interest and potential penalties.

How allowances affect withholding

For each exemption or allowance claimed, an amount equal to one personal exemption, prorated to the payroll period, is subtracted from the total amount of wages paid. This reduced amount, rather than the total wage amount, is subject to withholding. In other words, the personal exemption amount is $4,000 for 2015, meaning the prorated exemption amount for an employee receiving a biweekly paycheck is $153.85 ($4,000 divided by 26 paychecks per year) for 2015.

In addition, if an employee's expected income when offset by deductions and credits is low enough so that the employee will not have any income tax liability for the year, the employee may be able to claim a complete exemption from withholding.

Changing the amount withheld

Taxpayers may change the number of withholding allowances they claim based on their estimated and anticipated deductions, credits, and losses for the year.  For example, an employee who anticipates claiming a large number of itemized deductions and tax credits may wish to claim additional withholding allowances if the current number of withholding exemptions he is currently claiming for the year is too low and would result in overwithholding.

Withholding allowances are claimed on Form W-4, Employee's Withholding Allowance Certificate, with the withholding exemptions. An employer should have a Form W-4 on file for each employee. New employees generally must complete Form W-4 for their employer. Existing employees may update that Form W-4 at any time during the year, and should be encouraged to do so as early as possible in 2015 if they either owed significant taxes or received a large refund when filing their 2014 tax return.

The IRS provides an IRS Withholding Calculator at www.irs.gov/individuals that can help individuals to determine how many withholding allowances to claim on their Forms-W-4. In the alternative, employees can use the worksheets and tables that accompany the Form W-4 to compute the appropriate number of allowances.

Employers should note that a Form W-4 remains in effect until an employee provides a new one. If an employee does update her Form W-4, the employer should not adjust withholding for pay periods before the effective date of the new form. If an employee provides the employer with a Form W-4 that replaces an existing Form W-4, the employer should begin to withhold in accordance with the new Form W-4 no later than the start of the first payroll period ending on or after the 30th day from the date on which the employer received the replacement Form W-4.

Q: After what period is my federal tax return safe from audit? A: Generally, the time-frame within which the IRS can examine a federal tax return you have filed is three years. To be more specific, Code Sec. 6501 states that the IRS has three years from the later of the deadline for filing the return (usually April 15th for individuals) or, if later, the date you actually filed the return on a requested filing extension or otherwise. This means that if you file your 2014 return on July 10, 2015, the IRS will have until July 10, 2018 to look at it and "assess a deficiency;" not April 15, 2018.

Q: After what period is my federal tax return safe from audit?

A: Generally, the time-frame within which the IRS can examine a federal tax return you have filed is three years. To be more specific, Code Sec. 6501 states that the IRS has three years from the later of the deadline for filing the return (usually April 15th for individuals) or, if later, the date you actually filed the return on a requested filing extension or otherwise. This means that if you file your 2014 return on July 10, 2015, the IRS will have until July 10, 2018 to look at it and "assess a deficiency;" not April 15, 2018.

There are exceptions and caveats to this general principle, however. If you file prior to April 15, the IRS still has until April 15 of the third year that follows to audit your return. This means that if you filed an income tax return on February 10, 2017, you still won't be out-of-the-woods until April 15, 2020. For taxpayers who file fraudulent returns, incorrect returns with the intent to evade tax, and those who do not file at all, the IRS may open an audit at any time.

(Don't confuse the deadline for IRS tax assessments with your right to file a refund claim for an amount that you overpaid, either on a filed return or through withholding or estimated tax payments. That deadline is the later of three years from the filing deadline or two years from your last tax payment.)

You may also find some comfort in the practical IRS audit-cycle rhythm. While you are never truly beyond an audit until the statute of limitations has properly run, there are some general standards to keep in mind. Office audits are usually done within 1 1/2 years of the time the return was filed, and field office audits are complete by 2 1/2 years. The rule of thumb is that if you haven't been contacted within this time frame, you're probably not going to be. Especially for small businesses, the IRS has promised to shorten its normal audit cycle so that those taxpayers are not "left hanging" on potential tax liabilities (with interest and penalties) until the three-year limitations period has expired. Whether this shortened period happens, however, is still open to speculation. Most businesses should continue to make it a practice to keep "tax reserves" to cover such audit liabilities.
