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.
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.

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.

Casualty losses are damages from a sudden, unexpected or unusual event, including natural disasters. These losses are deductible to the extent they fit under specific tax rules. Ironically, however, due to insurance reimbursements and other payments, you may actually have taxable "casualty gain" as the result of a disaster or accident. Casualty losses and gains are reported on Form 4684.
Casualty losses are damages from a sudden, unexpected or unusual event, including natural disasters. These losses are deductible to the extent they fit under specific tax rules. Ironically, however, due to insurance reimbursements and other payments, you may actually have taxable "casualty gain" as the result of a disaster or accident. Casualty losses and gains are reported on Form 4684.
Casualty loss
The amount of casualty loss is based on the fair market value of the property immediately before it was damaged compared to its value immediately after the event. Alternatively, the loss determination can be based on the property's adjusted basis just before the loss. However, if business property (or property that produces income) is totally destroyed, the casualty loss is the adjusted basis of the property regardless of its fair market value. Whatever value you place on the loss, however, you then must deduct any insurance reimbursement that you receive or are likely to receive for that loss. That final figure is your official casualty loss for tax purposes.
Deductions
You can deduct a personal casualty loss only as an itemized deduction, only to the extent that it is more than $100 for any one event and only to the extent that all such losses over the course of the tax year are than 10 percent of your adjusted gross income. If the property is covered by insurance, you must file a claim for reimbursement. Otherwise, the loss cannot be deducted as a casualty loss. If the loss is on business property, the deduction is not restricted by the $100 or 10 percent rule. These restrictions apply only to personal casualty loss.
Disaster loss
A disaster loss can receive special treatment if it occurs in an area declared by the President of the United States to be eligible for federal disaster assistance. Typically, these are areas damaged by fire, hurricane or other natural disasters. A special rule allows you to deduct the loss in either the year in which the loss occurred or the preceding year. Claiming it in the preceding year typically allows you to file a refund claim immediately and, therefore, have immediate cash-in-hand from the deduction.
Gain
If your insurance reimbursement is more than your personal property's cost or basis (which may be the case if your property has increased in value since you bought it), you have a "personal casualty gain." If personal casualty gains from any year exceed personal casualty losses, a net capital gain results. Net capital gain generally is taxed at a maximum rate of 15 percent.
You may, however, be able to pay no tax on your gain. You can postpone net casualty gain using the so-called involuntary conversion rules. To postpone gain, you must purchase replacement property for a price equal to or more than the reimbursement you received.
You should beware of fancy footwork when it comes to estimating, filing, and paying federal taxes. One misstep can lead to harsh penalties. Willful or fraudulent mistakes can generate criminal sanctions as well.
Failure to pay tax
If you don't pay your taxes when due, the IRS may impose a penalty in addition to the tax. The addition to tax is one-half of one percent of the amount not paid, for each month (or part of a month) it remains unpaid, up to a maximum of 25 percent.
Delinquent returns
Failure to file on time may result in an "addition to tax" (the formal name that the IRS gives to its late-payment fee). This penalty is five percent for each month that no return is filed, up to 25 percent. If the return is not filed within 60 days of the due date (including extensions), the penalty will be at least $100 or 100 percent of the tax due on the return, whichever is less.
The penalty doesn't apply if you can show a reasonable cause for not filing. However, a "reasonable cause" for failure to file does not include (1) reliance on the advice of an agent; (2) reliance on the accountant to do the filing; or (3) misjudging the extension date.
Understatement of tax
If you substantially understate taxes due, the IRS can impose a 20 percent accuracy-related penalty. A "substantial understatement" occurs if the amount is (1) 10 percent of the tax required to be shown on the return (including self-employment tax) or (2) $5,000, which ever is greater.
You may be able to avoid this penalty if:
-- You acted in good faith and there was reasonable cause for the understatement;
-- The understatement was based on substantial authority; or
-- There was a reasonable basis for the tax treatment and the relevant facts were adequately disclosed.
Negligence, fraud, and criminal acts
If underpayment is due to negligent, reckless or intentional disregard of the tax laws, the IRS may impose a 20 percent accuracy-related penalty. Negligence includes failure to reasonably comply with the tax laws, to exercise reasonable care in preparing a tax return, to keep adequate books and records, or to properly substantiate items.
Fraud is punished more harshly. A penalty may be imposed on 75 percent of the underpayment due to fraud. The fraud penalty will not apply, however, if no return is filed, other than a return prepared by the IRS when a person fails to file a return. Criminal sanctions also are likely.
Frivolous returns
If you file a frivolous return, you risk a $500 penalty. A return is "frivolous" if it omits necessary information, shows a substantially incorrect tax, is based on a frivolous position, or is filed in an attempt to avoid tax collection. Changing or crossing-out the "penalty of perjury" language above the signature line on a return is treated as filing a frivolous return.
