The bill strengthens rules, guidance, and penalties to curb related-party partnership tax avoidance and improve enforcement clarity, but does so at the cost of higher taxes, greater compliance complexity, and increased penalty risk for affected partnerships and their owners.
All taxpayers will benefit from increased Treasury authority and required guidance, which should reduce ambiguity, improve consistency in IRS enforcement, and make compliance expectations clearer.
Partners in related-party partnerships will face clearer limits on basis-shifting and mandatory gain recognition, reducing opportunities for intra-group tax avoidance.
Partners subject to understatement rules will face higher (40%) accuracy-related penalties tied to related-party partnership distributions, strengthening compliance incentives and deterring abusive transactions.
Owners and partners in related-party and small partnerships may face higher tax liabilities when distributions or transfers trigger mandatory gain recognition.
Partnerships (especially those with related partners), their owners, and financial-advisors will face increased compliance complexity and higher tax-preparation costs because of new basis and character rules.
Taxpayers may incur large, unexpected 40% accuracy-related penalties during transition or due to misapplication of the new rules, increasing financial risk for small businesses and partnerships.

Introduced June 17, 2025 by Ronald Lee Wyden · Last progress June 17, 2025
Imposes mandatory recognition and limits on basis increases for certain partnership distributions and transfers between related partners. The bill changes how partners and partnerships recognize gain when partnership property is distributed or transferred among related parties, narrows the ability to increase tax basis through related-party transactions, raises the penalty rate for understatements tied to these rules, and directs Treasury to issue implementing regulations. These rules apply to distributions and transfers after June 11, 2025, and include a carve-out for small businesses and anti-abuse/regulatory authority language. The amendments redefine which partnerships and transfers are covered (generally partnerships with related partners and transfers among related parties), require mandatory application of existing basis-adjustment rules in covered cases, cap transferee basis increases to recognized gain, and align the character of recognized gain with ordinary or sale/exchange treatment as specified. A new accuracy-related penalty category increases the penalty rate for understatement attributable to these related-party partnership rules from 20% to 40%.
