This is a rough estimate. The calculator uses 2025
federal brackets, the OBBB-adjusted standard deduction, and a
simplified QBI deduction (assumes you're below the income threshold).
It does not account for the additional Medicare tax, AMT, capital
gains rates, child or dependent credits, itemized deductions, state
tax, or the dozens of other factors that affect a real return.
Numbers can be off by hundreds or thousands depending on your
situation. Use this as a planning starting point, then
work with a tax professional
for an accurate calculation.
