Here are the latest broad developments in U.S. taxation as of May 2026.
-
Federal tax legislation and administration updates
- There are ongoing discussions in Congress about a broader tax administration package that could affect IRS operations, enforcement, and tax code conformity across various years. This is part of a larger set of bills that have progressed through committees and may face Senate deliberation before any enactment. [Source: Current Federal Tax Developments coverage of H.R. 6495, H.R. 227, H.R. 6431, H.R. 6956, H.R. 7971, H.R. 7959; and mentions of S. 3931 for broader package][1]
- The Treasury and IRS issued a Notice of Proposed Rulemaking to update regulations in response to recent statutory changes under a 2025 law, reflecting adjustments to the tax framework (e.g., OBBA). Final rules will depend on the regulatory process and potential public comments.[1]
-
State and multi-state tax developments
- Several states are adjusting conformity to federal rules and adopting new tax measures. Examples include Virginia implementing a fantasy sports tax, Arkansas treating certain franchise sales as nonbusiness income for state tax purposes, and other states issuing multistate updates on conformity and tax policy changes. These moves can affect how residents and businesses compute state taxable income.[3]
-
Tax administration and compliance context
- Public discussion and media coverage highlight ongoing tax filing dynamics, including how changes to the law, or proposed changes, could influence refunds, credits (like working families credits), and the timing of tax relief measures, though most items remain subject to legislative action or regulatory finalization.[2][4]
