Tax Calculator US - Tax47
Refund, OBBB & EITC Estimator
Free · In‑App Purchases · Designed for iPad
Estimate your tax refund in seconds. See how the Big Beautiful Bill affects your 2025 taxes. Check EITC eligibility and self-employment taxes. 100% private.
Perfect app for:
- Estimating your tax refund before filing
- Checking if you withheld enough from paychecks
- Comparing 2024 vs 2025 taxes under the new Big Beautiful Bill
- Calculating Earned Income Tax Credit eligibility
- Self-employment tax and quarterly estimates
- Understanding how credits reduce what you owe
We created Tax47 because we kept asking ourselves:
Will I get a refund this year or owe money to the IRS?
- How much should I expect back?
- Did I withhold enough from my paychecks?
- How do my credits reduce what I owe?
- What is my actual tax rate after deductions?
And we wanted something simple that could quickly answer these questions right on the phone, with no data leaving the device.
The app solves the problem of knowing where you stand before filing. Enter your annual income and the federal taxes already withheld from your paychecks. Tax47 calculates your total tax liability, applies all eligible credits, and compares it against what you have already paid throughout the year.
If your withholding exceeds your tax bill, you will see your estimated refund amount. If you owe more than you paid, the app shows exactly how much you need to set aside before the deadline. No surprises when you file.
The refund calculator breaks down exactly how credits reduce what you owe. See how the Child Tax Credit, Childcare Credit, and Earned Income Tax Credit work in your favor. The app shows your effective tax rate too, so you understand what percentage of your income actually goes to federal taxes after all deductions and credits are applied.
Planning ahead? Save multiple calculations to compare different scenarios. See how a raise, a new job, or changes to your withholding would affect your refund.
Beyond the refund estimator, Tax47 includes three additional calculators:
OBBB (One Big Beautiful Bill) - Compare your taxes under the 2024 law against the 2025 law side-by-side. The new P.L. 119-21 introduces deductions for tips and overtime income, plus a car loan interest deduction for US-assembled vehicles. See exactly how the new law affects your bottom line.
Earned Income Tax Credit (EITC) - Check your eligibility and calculate your credit amount. The app shows your phase position and how far you are from maximizing your credit.
Self-Employment Tax - Calculate your SE tax obligations including Social Security, Medicare, and the additional Medicare tax. See quarterly payment estimates and the deductible portion.
All calculations follow IRS formulas exactly. The app handles tax brackets, standard and itemized deductions, child tax credits, childcare credits, SALT deductions, qualified business income, and Social Security taxation.
Customize the look with 16 themes. No account required, no data collected, everything stays on your device.
