Main Street Tax Certainty Act

S 213, the Main Street Tax Certainty Act, makes the qualified business income deduction permanent for small business owners. It directly affects pass-through business owners (like sole proprietors and small partnerships) who currently benefit from this tax break. The bill removes the temporary expiration of Section 199A of the tax code, providing long-term certainty for these taxpayers by ensuring they can continue deducting up to 20% of their qualified business income.
