Understanding your results
Toggle between Family and Non-family heirs to see different exemption thresholds and tax rates. Enable Gift Tax to include gifts made during the lifetime. The pie chart shows the distribution of estate value between tax and heirs.
Filing and exemptions
Inheritance tax returns must be filed within 150 days of the inheritance. Certain assets are exempt: assets inherited by a spouse, assets used for charitable/religious purposes, and life insurance proceeds. Planning with annual gifts under the exemption threshold can reduce the taxable estate.
