Available soonWhy SmallBizCalcs?
Running a small business means juggling dozens of compliance requirements across federal and state regulations. Payroll taxes alone involve calculating FICA contributions, federal unemployment tax, and state-specific unemployment rates that vary wildly — from 0.54% in South Carolina to over 4% in New York.
Most online calculators are either lead-generation forms disguised as tools (enter your email to see results!) or oversimplified widgets that ignore state-level differences. SmallBizCalcs is different. Every calculator on this site gives you real results immediately, uses current tax rates and wage bases, and breaks down the math so you understand what you're paying and why.
Our tools are designed for business owners with 1 to 50 employees who need quick, reliable estimates for budgeting, hiring decisions, and compliance planning. They are not a substitute for a qualified accountant or tax professional, but they are a solid starting point for understanding your obligations.
