This Week at the Internal Revenue Service — week of June 1, 2026

This week, the IRS and other federal agencies finalized updates to the surprise medical bill dispute process, proposed a fee increase for estate tax closing letters, and scheduled hearings on several pending regulations. Most actions are procedural, but the medical billing rules affect patients directly.

Surprise medical bills: dispute resolution rules finalized

• Several federal agencies issued final rules updating the process for settling payment disputes between health plans and out-of-network providers, under the No Surprises Act.
• The updates clarify how insurers and providers resolve payment disputes quickly and reinforce patient protections against balance billing in specific scenarios.
• This is largely an administrative update to keep the dispute resolution mechanism legally compliant and functional, rather than a new policy for patients.

Estate tax administration: proposed fee increase

• The IRS proposed raising the fee for an estate tax closing letter from $56 to $76.
• The fee applies to requests by authorized persons, such as executors or trustees, who need official confirmation that the IRS has finished reviewing a federal estate tax return.
• This is a minor administrative change that keeps the service self-sustaining; it adds $20 to most estates’ closing costs.

Rulemaking hearings and transition timelines

• The Treasury Department and IRS proposed a transition period for new foreign government tax rules originally proposed in December 2025. The rules address whether buying debt counts as commercial activity and what constitutes effective control of an entity by a foreign government. The transition period gives foreign sovereign wealth funds and investment vehicles time to adjust portfolios without immediate reclassification, preventing retroactive application.
• The IRS scheduled a public hearing on proposed tax-exempt refunding bond rules (REG-117298-21), following publication in the Federal Register on March 12, 2026. This affects mainly bond issuers, underwriters, and tax professionals.
• The IRS scheduled a public hearing on proposed rules for “Trump Accounts” (REG-117270-25), following the initial proposal published in March 2026. For most people, no immediate action is required beyond monitoring the Federal Register for final rules.
