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 released the optional standard mileage rates for 2019. Most taxpayers may use these rates to compute deductible costs of operating vehicles for:

The IRS released the optional standard mileage rates for 2019. Most taxpayers may use these rates to compute deductible costs of operating vehicles for:

• business,
• medical, and
• charitable purposes.

Some members of the military may also use these rates to compute their moving expense deductions.

2019 Standard Mileage Rates
The standard mileage rates for 2019 are:

• 58 cents per mile for business uses;
• 20 cents per mile for medical uses; and
• 14 cents per mile for charitable uses.

Taxpayers may use these rates, instead of their actual expenses, to calculate their deductions for business, medical or charitable use of their own vehicles.

FAVR Allowance for 2019
For purposes of the fixed and variable rate (FAVR) allowance, the maximum standard automobile cost for vehicles places in service after 2018 is:

• $50,400 for passenger automobiles, and
• $50,400 for trucks and vans.

Employers can use a FAVR allowance to reimburse employees who use their own vehicles for the employer’s business.

2019 Mileage Rate for Moving Expenses
The standard mileage rate for the moving expense deduction is 20 cents per mile. To claim this deduction, the taxpayer must be:

• a member of the Armed Forces of the United States,
• on active military duty, and
• moving under an military order and incident to a permanent change of station.

The Tax Cuts and Jobs Act of 2017 suspended the moving expense deduction for all other taxpayers until 2026.

Unreimbursed Employee Travel Expenses
For most taxpayers, the Tax Cuts and Jobs Act suspended the miscellaneous itemized deduction for unreimbursed employee travel expenses. However, certain taxpayers may still claim an above-the-line deduction for these expenses. These taxpayers include:

• members of a reserve component of the U.S. Armed Forces,
• state or local government officials paid on a fee basis, and
• performing artists with relatively low incomes.

Notice 2018-3, I.R.B. 2018-2, 285, as modified by Notice 2018-42, I.R.B. 2018-24, 750, is superseded.

The IRS has released long-awaited guidance on new Code Sec. 199A, commonly known as the "pass-through deduction" or the "qualified business income deduction." Taxpayers can rely on the proposed regulations and a proposed revenue procedure until they are issued as final.

The IRS has released long-awaited guidance on new Code Sec. 199A, commonly known as the "pass-through deduction" or the "qualified business income deduction." Taxpayers can rely on the proposed regulations and a proposed revenue procedure until they are issued as final.

Code Sec. 199A allows business owners to deduct up to 20 percent of their qualified business income (QBI) from sole proprietorships, partnerships, trusts, and S corporations. The deduction is one of the most high-profile pieces of the Tax Cuts and Jobs Act ( P.L. 115-97).

In addition to providing general definitions and computational rules, the new guidance helps clarify several concepts that were of special interest to many taxpayers.

Trade or Business

The proposed regulations incorporate the Code Sec. 162 rules for determining what constitutes a trade or business. A taxpayer may have more than one trade or business, but a single trade or business generally cannot be conducted through more than one entity.

Taxpayers cannot use the grouping rules of the passive activity provisions of Code Sec. 469 to group multiple activities into a single business. However, a taxpayer may aggregate trades or businesses if:

• each trade or business is itself a trade or business;
• the same person or group owns a majority interest in each business to be aggregated;
• none of the aggregated trades or businesses can be a specified service trade or business; and
• the trades or businesses meet at least two of three factors which demonstrate that they are in fact part of a larger, integrated trade or business.

Specified Service Business

Income from a specified service business generally cannot be qualified business income, although this exclusion is phased in for lower-income taxpayers.

A new de minimis exception allows some business to escape being designated as a specified service trade or business (SSTB). A business qualifies for this de minimis exception if:

• gross receipts do not exceed $25 million, and less than 10 percent is attributable to services; or
• gross receipts exceed $25 million, and less than five percent is attributable to services.

The regulations largely adopt existing rules for what activities constitute a service. However, a business receives income because of an employee/owner’s reputation or skill only when the business is engaged in:

• endorsing products or services;
• licensing the use of an individual’s image, name, trademark, etc.; or
• receiving appearance fees.

In addition, the regulations try to limit attempts to spin-off parts of a service business into independent qualified businesses. Thus, a business that provides 80 percent or more of its property or services to a related service business is part of that service business. Similarly, the portion of property or services that a business provides to a related service business is treated as a service business. Businesses are related if they have at least 50-percent common ownership.

Wages/Capital Limit

A higher-income taxpayer’s qualified business income may be reduced by the wages/capital limit. This limit is based on the taxpayer’s share of the business’s:

• W-2 wages that are allocable to QBI; and
• unadjusted basis in qualified property immediately after acquisition.

The proposed regulations and Notice 2018-64, I.R.B. 2018-34, provide detailed rules for determining the business’s W-2 wages. These rules generally follow the rules that applied to the Code Sec. 199 domestic production activities deduction.

The proposed regulations also address unadjusted basis immediately after acquisition (UBIA). The regulations largely adopt the existing capitalization rules for determining unadjusted basis. However, "immediately after acquisition" is the date the business places the property in service. Thus, UBIA is generally the cost of the property as of the date the business places it in service.

Other Rules

The proposed regulations also address several other issues, including:

• definitions;
• basic computations;
• loss carryovers;
• Puerto Rico businesses;
• coordination with other Code Sections;
• penalties;
• special basis rules;
• previously suspended losses and net operating losses;
• other exclusions from qualified business income;
• allocations of items that are not attributable to a single trade or business;
• anti-abuse rules;
• application to trusts and estates; and
• special rules for the related deduction for agricultural cooperatives.

Effective Dates

Taxpayers may generally rely on the proposed regulations and Notice 2018-64 until they are issued as final. The regulations and proposed revenue procedure will be effective for tax years ending after they are published as final. However:
