Use this calculator to estimate the capital gains taxes that would be due as a result of the sale of an asset (investment property or primary residence) held for more than one year. Federal (and Medicare) and CA State CAP GAINS tax rates are set forth at the bottom of this page. Although this overly simplified calculator will provide some insight, it is an approximation only. Note that this calculator assumes worse case / highest tax rates without application of any applicable §121 exemption; your results may differ. Do not rely on the results without the added / needed advice and guidance of a tax or legal professional. A complete analysis required substantially more details and nuance that contribute to a full financial, tax, estate planning, and legal analysis.
