Oregon Enacts SB 951, Restricting PE-Backed MSOs in Physician Practice Transactions
On June 9, 2025, Oregon enacted Senate Bill 951 (SB 951), a sweeping new law significantly limiting how management services organizations (MSOs)—including those backed by private-equity firms—may engage with physician practices. The legislation targets traditional “friendly provider” models by restricting ownership and operational control of professional medical entities and voiding restrictive covenants. Investors must now reassess Oregon-based physician practice investments to ensure compliance by 2026 (for new MSOs) and 2029 (for existing ones). It’s noteworthy that this law will coexist with Oregon’s complicated health care transactions notice law, a law that requires a thorough review of certain health care transactions.

The U.S. income tax system is based on voluntary compliance, and it is the taxpayer’s responsibility to report all income and to pay all taxes due.

A tax authority is a government body or agency responsible for collecting taxes, administering tax laws, and enforcing tax compliance. In the United States, the Internal Revenue Service (IRS) is the federal tax authority. Most states, territories, and local jurisdictions also have tax authorities to ensure compliance with applicable state and local laws and regulations. These tax authorities are generally responsible for collecting taxes, administering tax laws, and enforcing tax compliance in their respective jurisdictions.

A tax controversy is a dispute between a taxpayer and a tax authority such as the United States Internal Revenue Service (IRS) concerning whether the taxpayer has properly reported and paid their tax liability, and otherwise complied with applicable tax law. A tax controversy may concern a disagreement regarding the correct amount of tax or the manner in which the IRS is attempting to collect tax, as well as whether penalties are appropriate. Tax controversies may be resolved administratively or in litigation.
