Main Street Tax Certainty Act

HR 703, the Main Street Tax Certainty Act, makes a key tax deduction permanent for small business owners. It removes the temporary sunset provision (subsection (i)) from Section 199A of the tax code, ensuring the qualified business income deduction remains available for eligible small businesses. This change directly affects pass-through business owners (like S-corps, partnerships, and sole proprietorships) who currently qualify for this deduction. The permanent change takes effect for tax years starting after December 31, 2025.
