The National Federation of Independent Business (NFIB), the nation’s leading small business advocacy organization, has released two new digital tools to help small business owners, policymakers, and the public in South Carolina understand the significant economic impact of the 20% Small Business Tax Deduction and what’s at stake if Congress fails to make it permanent.

The new tools include an interactive map that allows users to explore how extending the Small Business Deduction would power job creation and GDP growth in every congressional district across South Carolina. NFIB also launched a tax calculator to provide small business owners in South Carolina with personalized estimates of how much more they could owe in federal income taxes in 2026 if the deduction expires.

“South Carolina’s economy is built on its small businesses,” said NFIB State Director Ben Homeyer. “Allowing this essential deduction to expire would be a major blow to small businesses and their communities.”

According to NFIB’s interactive map, if the deduction is extended, South Carolina could see an increase of almost 35,000 jobs and $1.7 billion in GDP over the next decade. The district-level data allow lawmakers and local leaders to understand exactly how small businesses in their communities stand to gain when the tax deduction is made permanent, or lose if it is not.

The tax calculator helps individual small business owners project their potential tax increase if the deduction is not extended. For example, a South Carolina small business owner with a personal income of $75,000 and qualified business income of $150,000 could see a tax increase of more than $13,000, depending on their full financial profile.

We also applaud the U.S. House of Representatives for passing the One Big Beautiful Act this morning. The One Big Beautiful Bill Act is one of the most pro-small business pieces of legislation in recent history, and Congress has a historic opportunity to provide over 33 million small business owners with permanent tax relief.
