Main Street Tax Certainty Act

The Main Street Tax Certainty Act permanently extends the 20% tax deduction for qualified business income (QBI), which currently applies to owners of pass-through businesses like sole proprietorships, partnerships, and S corporations. The bill achieves this by amending the tax code to remove an expiration date (via striking subsection (i) of Section 199A of the Internal Revenue Code). This change directly affects small business owners who rely on the QBI deduction to reduce their taxable income. The key provision eliminates uncertainty about the deduction’s future, ensuring continued eligibility without requiring future legislative action.
