Not Financial or Tax Advice

The mathematical models, algorithms, and take-home estimations rendered by NumBoxHub are generated purely for directional reference and educational utility. None of the processed outputs constitute formal financial planning, certified public accountancy (CPA) consultations, or statutory legal tax counseling.

Accuracy & Official Sources

Our calculators use formulas based on published tax brackets and rates from official government sources:

  • US Federal Tax: IRS Revenue Procedure 2025-41 (Tax Year 2026)
  • US State Tax: Individual state revenue department publications
  • German Tax: BMF ยง32a EStG (Einkommensteuergesetz) 2026
  • Social Security: SSA and Deutsche Rentenversicherung rates

However, actual tax liability may differ due to individual circumstances such as itemized deductions, tax credits, local taxes, pre-tax contributions (401k, HSA), and other factors not captured by our simplified models.

No Guarantee of Accuracy

While we strive to keep our calculations current and accurate, tax laws change frequently. We make no warranties or representations regarding the completeness, accuracy, or reliability of any results generated by our tools. Results should be verified against official IRS, state, or BMF publications before filing.

Professional Consultation Recommended

For tax filing, financial planning, or legal decisions, we strongly recommend consulting a licensed tax professional, CPA, or Steuerberater. NumBoxHub assumes no liability for any financial losses, penalties, or damages arising from reliance on our calculator outputs.
