Main Street Tax Certainty Act

HR 4721, the Main Street Tax Certainty Act, makes a permanent the 20% tax deduction for eligible small business owners under Section 199A of the tax code. This provision directly affects pass-through business owners (like S-corps, partnerships, and sole proprietorships) who qualify for the deduction. The bill achieves this by removing the temporary expiration language (subsection (i)) from the existing tax code provision. The key change is ending the need for annual congressional extensions of this deduction, providing long-term tax certainty for small businesses.
