- State-specific rules — State tax calculators use generalized state tax rates and may not reflect local taxes, credits, or special provisions.
- User input errors — Results depend entirely on the accuracy of information you provide. Incorrect inputs produce incorrect results.

Summary
TaxWiser is a helpful starting point for tax planning and education, but it is not a replacement for professional advice.

When in doubt, consult a professional. It's always better to be safe than sorry when it comes to taxes.
