Should limited partners have to be actively involved in business operations to qualify for tax exemptions?
K Alain LLLP, formerly known as Sirius Solutions LLLP, has filed a petition asking the US Court of Appeals for the Fifth Circuit for a rehearing. The company is challenging an August ruling regarding the requirements for self-employment tax exemptions within partnerships.
Why it matters
