1099 Write Off Calculator

If you’re self-employed, a freelancer, gig worker, or contractor receiving 1099 income, understanding your tax liabilities is critical. One of the biggest advantages of being self-employed is the ability to deduct business expenses—commonly referred to as write-offs. These write-offs can significantly reduce your taxable income, and therefore, your total tax bill.

Our 1099 Write-Off Calculator is a simple yet powerful tool designed to help you quickly estimate your net taxable income and tax savings from your business expenses. Whether you’re new to freelancing or a seasoned entrepreneur, this tool provides clarity and helps you plan ahead for tax season.
