Official title: Amend the Internal Revenue Code of 1986 to improve the rules related to partners and partnerships, and for other purposes.
Introduced June 17, 2025 by Ronald Lee Wyden · Last progress June 17, 2025
The bill trades broader, clearer statutory rules and administrative clarity for partnerships (reducing technical ambiguities) against higher taxes for many partners, more regulatory authority, and materially increased compliance and litigation costs for partnerships, investors, and tax administrators.
Millions of partnership owners, small-business owners, financial institutions, and individual taxpayers will face clearer, more standardized tax rules across many partnership issues (allocation of liabilities, built-in gains/losses, revaluation, reporting, termination rules), reducing ambiguity for filing and audits.
Small partnerships meeting statutory tests keep key reliefs—qualified small partnerships can still elect Section 754 basis adjustments and certain small/service businesses can avoid revaluation rules for a year—preserving tax flexibility for many small businesses.
Partners who recognize gain from certain liability re‑allocations may elect to pay that additional tax in six equal annual installments, easing immediate cash‑flow burdens for affected partners.
Many partners and small‑business owners may face higher tax bills or less favorable allocations because the bill broadens circumstances that produce ordinary income, built‑in gain recognition, reallocation of liabilities, and revaluation adjustments.
Partnerships, investors, financial institutions, and tax preparers will face substantially higher compliance, recordkeeping, and administrative costs (and likely higher professional fees) to apply new allocation rules, track historical contributions, file new reports, and implement Treasury guidance.
The bill expands Treasury/IRS rulemaking and recharacterization powers in key areas, increasing audit exposure and creating fact‑intensive standards that are likely to generate disputes and litigation over whether transactions reflect economic substance.
Based on analysis of 16 sections of legislative text.
Overhauls partnership tax rules: tightens basis adjustments and allocations, expands the NIIT base for high‑income taxpayers, treats many transfers into pooled funds as taxable, and adds Treasury anti‑abuse authority.
Makes broad, detailed changes to partnership and partnership-related tax rules to limit tax-driven basis adjustments and shelters, tighten allocation and reporting rules, expand the base of the 3.8% net investment income tax for high‑income taxpayers, and give Treasury clearer authority to recast abusive partnership transactions. The bill changes when losses on partnership interests are recognized, requires standardized allocation methods for certain controlled partnerships, restricts special basis elections to small partnerships, treats transfers into pooled-investment entities as taxable in many cases, removes time limits that previously constrained built‑in gain recapture, and adds new reporting, payment‑installment, and regulatory authorities to enforce the rules. The package is largely technical and highly detailed but substantively far‑reaching: it raises compliance and reporting burdens for partnerships (especially investment vehicles and partnerships controlled by related groups), expands tax liability for some high‑income individuals and investors, curtails certain tax-motivated partnership structures, and grants the Treasury Secretary new anti‑abuse powers and rulemaking mandates. Many provisions take effect for taxable years beginning after enactment or after Dec 31, 2025, with some transitional election and installment-payment rules provided for affected taxpayers.
