Marin Mountain Bikes sues IRS in tax court
July 21, 2026
Marin Mountain Bikes is suing the IRS in Tax Court after receiving a notice of deficiency that says it owes about $4.5 million in taxes and penalties for 2021 and 2022. The company says the IRS misvalued its business and disputes the agency’s treatment of Marin’s net operating loss deductions, calling the filing a procedural step toward IRS Appeals.
The dispute traces back to a 2018 loan conversion and later loss carryovers, and Marin says it remains optimistic about a favorable resolution. BRAIN
