The Summary Tab displays the taxable portion of a GRIT. To calculate this value, the calculation determines the value of the interest retained by the grantor (income interest plus reversion). It then subtracts the value of the grantor’s retained interest from the principal placed into the trust. The result is the taxable portion of the GRIT. The Taxable Gift, the Value of Property after three years, and the Potential Death Tax Savings (Combined Bracket times [value of Property minus Taxable Gift]) are also shown in the results.
