Small Business Tax Fairness and Compliance Simplification Act

This bill extends a tax credit for employer social security taxes paid on employee tips at beauty service businesses (including barbering, nail care, esthetics, and spa treatments), but only for tips customary in these services. It creates a "tip reporting safe harbor" requiring beauty businesses to implement quarterly employee training on tip reporting, monthly tip tracking, and proper tax filings to avoid IRS audits on tips. Additionally, it mandates businesses renting space to beauty service providers to report annual rental income over $600 to the IRS. These provisions directly affect beauty service establishments and landlords in this sector, applying to tax years beginning after 2022 or 2023.
