Welcome to the Tax Form Calculator, the free online calculator for Federal Tax and State Tax Calculations. We have supported millions of free tax calculations during our 12 years of providing this tool (around 104400000 by our estimation!). You can calculate and estimate your 2025/26 tax return simply by entering your annual salary in the quick tax calculator below. If you wish to calculate your tax return for a previous tax year, simply select an earlier tax year. The quick tax calculator uses 2025 State tax tables as default and will allow you to calculate tax deductions back to the 2020 tax year. You can calculate your annual tax return back as far as 2013 using the individual State Tax Calculators.
The Federal Tax Calculator is updated for the 2025/26 tax year and is designed for quick online tax calculations by entering your gross (total) income from tax form 1040 and your gross expenses from tax form 1040 for 2025/26. For more detailed tax calculations, please use the US State Tax calculators. This tax calculator is free to use, our only request is that you provide feedback if you spot an error and share on your favourite social media platform to help other make use of this tool.
This tax calculator is as good as the feedback, your support, requests and bug catches help to improve the accuracy of the tax calculator for all.
This tax calculator aims to balance ease of use with transparency of tax calculation but is provided for illustration only. Remember that you should always seek professional advice and audit your tax return
