Why Write-Offs Are Your Greatest Wealth Builder
As a W-2 employee, standard deductions are capped. But as a 1099 independent contractor or sole proprietor, you are taxed exclusively on net profit, not gross revenue:
$$\text{Taxable Business Profit} = \text{Gross Revenue} - \text{Allowable Schedule C Deductions}$$
Every $1,000 of legitimate business expenses you claim on IRS Schedule C saves you approximately $250 to $420 in cold hard cash by slashing your 15.3% SECA tax and progressive income tax brackets simultaneously! You can simulate these deductions on our Paycheck Splitter or check state-specific deductions in our 50 US State Guides.
