U Tax Calculator vs 1040-ES Usage & Stats
With this easy-to-use tool, you can quickly estimate your "federal tax refund or amount owed" for both the "current year, next year and the previous year". The app is designed for convenience and clarity, using "standard IRS deductions" to generate estimates based on your filing status.
Supported filing categories include:
- Married Filing Jointly
- Married Filing Separately
- Single Filing
- Head of Household Filing
For those filing, you can enter eligible dependents (excluding your spouse), including children. Children under the age of 17 are factored into the estimate through the "Child Tax Credit", where applicable.
Important Disclaimer:
This app provides a "rough estimate only", based on standard deductions and commonly applied credits. It does "not account for itemized deductions, special tax situations, or recent tax law changes", and there is "no guarantee" that your actual tax return will match the estimate shown.
Always consult a qualified tax professional or official IRS resources for precise tax calculations.
