About these tools
Are the tools really free?
Yes. There's no sign-up and no email required. Use them as often as you like.
Do you save the numbers I enter?
No. The calculators run entirely in your browser, and nothing is sent to us unless you choose to fill out a form.
Is this tax advice?
No. The tools give estimates for general information. Your actual tax depends on your full situation, which is what a consultation is for.
How current are the numbers?
The calculators use 2026 federal tax brackets, standard deductions and the Social Security wage base. We update them every January.
