The U.S. Tax Court lacks jurisdiction over a taxpayer’s appeal of a levy in a collection due process hearing when the IRS abandoned its levy because it applied the taxpayer’s later year overpayments to her earlier tax liability, eliminating the underpayment on which the levy was based. The 8-1 ruling by the Court resolves a split between the Third Circuit and the Fourth and D.C. Circuit.

The U.S. Tax Court lacks jurisdiction over a taxpayer’s appeal of a levy in a collection due process hearing when the IRS abandoned its levy because it applied the taxpayer’s later year overpayments to her earlier tax liability, eliminating the underpayment on which the levy was based. The 8-1 ruling by the Court resolves a split between the Third Circuit and the Fourth and D.C. Circuit.

The IRS determined that taxpayer had a tax liability for 2010 and began a levy procedure. The taxpayer appealed the levy in a collection due process hearing, and then appealed that adverse result in the Tax Court. The taxpayer asserted that she did not have an underpayment in 2010 because her then-husband had made $50,000 of estimated tax payments for 2010 with instructions that the amounts be applied to the taxpayer’s separate 2010 return. The IRS instead applied the payments to the husband’s separate account. While the agency and Tax Court proceedings were pending, the taxpayer filed several tax returns reflecting overpayments, which she wanted refunded to her. The IRS instead applied the taxpayer’s 2013-2016 and 2019 tax overpayments to her 2010 tax debt.

When the IRS had applied enough of the taxpayer’s later overpayments to extinguish her 2010 liability, the IRS moved to dismiss the Tax Court proceeding as moot, asserting that the Tax Court lacked jurisdiction because the IRS no longer had a basis to levy. The Tax Court agreed. The taxpayer appealed to the Third Circuit, which held for the taxpayer that the IRS’s abandonment of the levy did not moot the Tax Court proceedings. The IRS appealed to the Supreme Court, which reversed the Third Circuit.

The Court, in an opinion written by Justice Barrett in which seven other justices joined, held that the Tax Court, as a court of limited jurisdiction, only has jurisdiction under Code Sec. 6330(d)(1) to review a determination of an appeals officer in a collection due process hearing when the IRS is pursuing a levy. Once the IRS applied later overpayments to zero out the taxpayer’s liability and abandoned the levy process, the Tax Court no longer had jurisdiction over the case. Justice Gorsuch dissented, pointing out that the Court’s decision leaves the taxpayer without any resolution of the merits of her 2010 tax liability, and “hands the IRS a powerful new tool to avoid accountability for its mistakes in future cases like this one.”

The Internal Revenue Service collected more than $5.1 trillion in gross receipts in fiscal year 2024. It is the first time the agency broke the $5 trillion mark, according to the 2024 Data Book, an annual publication that reviews IRS activities for the given fiscal year.

The Internal Revenue Service collected more than $5.1 trillion in gross receipts in fiscal year 2024.

It is the first time the agency broke the $5 trillion mark, according to the 2024 Data Book, an annual publication that reviews IRS activities for the given fiscal year. It was an increase over the $4.7 trillion collected in the previous fiscal year.

Individual tax, employment taxes, and real estate and trust income taxes accounted for $4.4 trillion of the fiscal 2024 gross collections, with the balance of $565 billion coming from businesses. The agency issued $120.1 billion in refunds, including $117.6 billion in individual income tax refunds and $428.4 billion in refunds to businesses.

The 2024 Data Book broke out statistics from the pilot year of the Direct File program, noting that 423,450 taxpayers logged into Direct File, with 140,803 using the program, which allows users to prepare and file their tax returns through the IRS website, to have their tax returns filed and accepted by the agency. Of the returns filed, 72 percent received a refund, with approximately $90 million in refunds issued to Direct File users. The IRS had gross collections of nearly $35.3 million (24 percent of filers using Direct File). The rest had a return with a $0 balance due.

Among the data highlighted in this year’s publication were service level improvements.

"The past two filing seasons saw continued improvement in IRS levels of service—one the phone, in person, and online—thanks to the efforts of our workforce and our use of long-term resources provided by Congress," IRS Acting Commissioner Michael Faulkender wrote. "In FY 2024, our customer service representatives answered approximately 20 million live phone calls. At our Taxpayer Assistance Centers around the country, we had more than 2 million contacts, increasing the in-person help we provided to taxpayers nearly 26 percent compared to FY 2023."

On the compliance side, the IRS reported in the 2024 Data Book that for all returns filed for Tax Years 2014 through 2022, the agency "has examined 0.40 percent of individual returns filed and 0.66 percent of corporation returns filed, as of the end of fiscal year 2024."

This includes examination of 7.9 percent of taxpayers filing individual returns reporting total positive incomes of $10 million or more. The IRS collected $29.0 billion from the 505,514 audits that were closed in FY 2024.

The Treasury Department and IRS have issued Notice 2025-33, extending and modifying transition relief for brokers required to report digital asset transactions using Form 1099-DA, Digital Asset Proceeds From Broker Transactions. The notice builds upon the temporary relief previously provided in Notice 2024-56 and allows additional time for brokers to comply with reporting requirements.

The Treasury Department and IRS have issued Notice 2025-33, extending and modifying transition relief for brokers required to report digital asset transactions using Form 1099-DA, Digital Asset Proceeds From Broker Transactions. The notice builds upon the temporary relief previously provided in Notice 2024-56 and allows additional time for brokers to comply with reporting requirements.

Reporting Requirements and Transitional Relief

In 2024, final regulations were issued requiring brokers to report digital asset sale and exchange transactions on Form 1099-DA, furnish payee statements, and backup withhold on certain transactions beginning January 1, 2025. Notice 2024-56 provided general transitional relief, including limited relief from backup withholding for certain sales of digital assets during 2026 for brokers using the IRS’s TIN-matching system in place of certified TINs.

Additional Transition Relief from Backup Withholding, Customers Not Previously Classified as U.S. Persons

Under Notice 2025-33, transition relief from backup withholding tax liability and associated penalties is extended for any broker that fails to withhold and pay the backup withholding tax for any digital asset sale or exchange transaction effected during calendar year 2026.

Brokers will not be required to backup withhold for any digital asset sale or exchange transactions effected in 2027 when they verify customer information through the IRS Tax Information Number (TIN) Matching Program. To qualify, brokers must submit a customer's name and tax identification number to the matching service and receive confirmation that the information corresponds with IRS records.

Additionally, penalties that apply to brokers that fail to withhold and pay the full backup withholding due are limited with respect to any decrease in the value of received digital assets between the time of the transaction giving rise to the backup withholding obligation and the time the broker liquidates 24 percent of a customer’s received digital assets.

Finally, the notice also provides additional transition relief for brokers for sales of digital assets effected during calendar year 2027 for certain preexisting customers. This relief applies when brokers have not previously classified these customers as U.S. persons and the customer files contain only non-U.S. residence addresses.

Notice 2025-33

IR-2025-67

The IRS failed to establish that it issued a valid notice of deficiency to an individual under Code Sec. 6212(b). Thus, the Tax Court dismissed the case due to lack of jurisdiction.

The IRS failed to establish that it issued a valid notice of deficiency to an individual under Code Sec. 6212(b). Thus, the Tax Court dismissed the case due to lack of jurisdiction.

The taxpayer filed a petition to seek re-determination of a deficiency for the tax year at issue. The IRS moved to dismiss the petition under Code Sec. 6213(a), contending that it was untimely and that Code Sec. 7502’s "timely mailed, timely filed" rule did not apply. However, the Court determined that the notice of deficiency had not been properly addressed to the individual’s last known address.

Although the individual attached a copy of the notice to the petition, the Court found that the significant 400-day delay in filing did not demonstrate timely, actual receipt sufficient to cure the defect. Because the IRS could not establish that a valid notice was issued, the Court concluded that the 90-day deadline under Code Sec. 6213(a) was never triggered, and Code Sec. 7502 was inapplicable.

L.C.I. Cano, TC Memo. 2025-65, Dec. 62,679(M)

A limited partnership classified as a TEFRA partnership was not entitled to exclude its limited partners’ distributive shares from net earnings from self-employment under Code Sec. 1402(a)(13). The Tax Court found that the individuals materially participated in the partnership’s investment management business and were not acting as limited partners “as such.”

A limited partnership classified as a TEFRA partnership was not entitled to exclude its limited partners’ distributive shares from net earnings from self-employment under Code Sec. 1402(a)(13). The Tax Court found that the individuals materially participated in the partnership’s investment management business and were not acting as limited partners “as such.”

Furthermore, the Court concluded that the limited partners’ roles were indistinguishable from those of active general partners. Accordingly, their distributive shares were includible in net earnings from self-employment under Code Sec. 1402(a) and subject to tax under Code Sec. 1401. The taxpayer’s argument that the partners’ actions were authorized solely through the general partner was found unpersuasive. The Court emphasized substance over form and found that the partners’ conduct and economic relationship with the firm were determinative.

Additionally, the Court held that the taxpayer failed to meet the requirements under Code Sec. 7491(a) to shift the burden of proof because it did not establish compliance with substantiation and net worth requirements. Lastly, the Tax Court also upheld the IRS’s designation of the general partner LLC as the proper tax matters partner under Code Sec. 6231(a)(7)(B), finding that the attempted designation of a limited partner was invalid because an eligible general partner existed and had the legal authority to serve.

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.

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.
