Why use a Freelance Tax Calculator?
As a freelancer, gig worker, or independent contractor, taxes aren't withheld from your paycheck automatically. You are responsible for paying both income tax and social contributions (like Social Security, National Insurance, or CPP).
Failing to estimate these taxes correctly can lead to a surprise bill and potential penalties. Our SoloTax Tax Estimator helps you:
- Calculate your Effective Tax Rate across different tax jurisdictions.
- Determine how much to set aside from every invoice (typically 25-30%).
- See the impact of business expenses and specific tax credits on your net income.
