About Tax47
Tax47 is a tax calculator app for US taxpayers who want to see their federal refund, or what they owe, before they file. This site has the free tax calculators and guides that go with it. You don't need the app to use them.
Who makes Tax47
Tax47 and this site are made by EHM Tech LLC, which builds mobile apps for iPhone and Android. Since 2019, over 500,000 people have used our apps. The "Tax47 Editorial Team" named on our guides is EHM Tech.
Where our numbers come from
Our calculators and guides follow the IRS. The main sources are the IRS's yearly inflation adjustments, its forms and publications, and the text of the One Big Beautiful Bill Act on Congress.gov. Most guides link to the exact IRS pages they use.
Every update goes through an automated check before it goes live. It compares our tax figures with the IRS figures for that year. If one is out of date, the update waits until it's fixed.
Results are estimates, not tax or legal advice. For your own return, ask a tax professional.
Your tax numbers stay on your phone
Tax47 does all of its tax math on your phone and saves your returns there. We never see your income, deductions or results. The app does send anonymous usage stats and crash reports so we can fix bugs, and the privacy policy lists everything it collects.
