How to Use Our Income Tax Calculator

Figuring out how much of your income goes to taxes can be confusing. Our Income Tax Calculator makes it easy to get a quick estimate of your take-home pay after federal and state taxes. Here’s how it works and what to expect when using it.


🧾 Simple Input, Clear Output

The calculator is designed with a clean two-column layout:

  • Left column: where you enter your information
  • Right column: where the results appear instantly after clicking "Calculate"

Let’s walk through how to use it.


💡 Step-by-Step Guide

1. Choose Your State

Start by selecting your state from the dropdown menu. Since each state has its own income tax rules—or in some cases, no income tax at all—this step is essential for an accurate estimate.

2. Enter Your Total Income

Input your total annual income before any deductions or taxes. This is your gross income—the full amount you earn before anything is taken out.

3. Click "Calculate"

Once you've entered your income and selected your state, hit the "Calculate" button. The calculator will take it from there.


📊 Understanding the Results

Once calculated, your results will show up in the right-hand column, which is wider to allow for a full breakdown. The results are organized into clear sections:

💼 Pre-Tax Income

Your total income as entered is displayed first, so you can compare it directly with your after-tax figures.

🏛️ Federal and State Tax Breakdown

This section provides a detailed explanation of how your taxes are calculated.

Standard Deductions

We automatically apply the standard deduction based on current IRS guidelines (and your state, if applicable). This reduces your taxable income before any rates are applied.

Marginal Tax Rates

Your income is taxed in brackets. We'll show:

  • The tax rate that applies to each portion of your income
  • How much you're taxed in each bracket
  • Both for federal and state taxes

Total Tax

We add up the taxes owed to:

  • Federal government
  • Your state government

This gives you a total tax owed amount.

Effective Tax Rate

This is the percentage of your total income that goes to taxes, offering a clearer sense of your real tax burden:

  • Federal effective tax rate
  • State effective tax rate
  • Total effective tax rate

✅ What You Get

By the end, you’ll have a full picture of:

  • Your total tax liability
  • Your effective tax rates
  • A comparison of pre-tax vs. after-tax income

All without needing to dig through tax code or fill out a full tax return.


🔒 No Account Required

We don’t collect any personal info. Just enter your income, select your state, and see your estimate—fast and private.
