Creates a new tax credit rule that establishes a special "Credit for microemployers" by adding subsection (g) to Internal Revenue Code section 45E. The change adjusts two application rules of the existing credit framework (the rules in subsections (a) and (b)(1)) and includes a statutory definition of "qualified microemployer." The amendment applies to taxable years beginning after December 31, 2024.

The provision mainly affects very small employers who meet the new "qualified microemployer" definition by making the existing credit more specifically available to them and changing how the credit is applied. The IRS will need to issue guidance and update forms to implement the new subsection; employers will need to track eligibility and claim the credit on tax returns for affected years.
