Detailed Comparison
The Income Tax Estimator calculates federal income tax liability for W-2 employees based on filing status, deductions, and credits. The Self-Employment Tax Calculator focuses on the additional 15.3% SE tax that freelancers and sole proprietors owe on top of income tax. Most self-employed individuals need both tools.
When to use US Income Tax Estimator
Use the Income Tax Estimator when you earn a traditional salary or wages and want to estimate your federal tax bill. It accounts for standard or itemized deductions, tax credits, and marginal brackets without SE tax considerations.
When to use US Self-Employment Tax Calculator
Use the Self-Employment Tax Calculator when you have 1099 or freelance income. It computes both the Social Security and Medicare portions of SE tax and shows your combined liability including the deductible half of SE tax.
The Verdict
W-2 earners only need the Income Tax Estimator. Self-employed workers should run both tools to see their full tax picture.
