“Adjusted taxable estate”, the sum of the taxable estate, as defined in section 2051 of the Code, and any taxable gifts, as defined in section 2503 of the Code, with a Massachusetts situs made by the decedent within 3 years of the date of death, less the exemption as determined under this subsection.

For calendar years beginning on or after January 1, 2022, the exemption shall be $1,000,000 increased by an amount equal to $1,000,000 multiplied by the percentage, if any, by which the CPI for the preceding calendar year exceeds the CPI for calendar year 2021. If the amount as adjusted under the preceding sentence is not a multiple of $10,000, such amount shall be rounded to the nearest multiple of $10,000.

(b) A tax is hereby imposed upon the transfer of the estate of each person dying on or after January 1, 2021 who, at the time of death, was a resident of the commonwealth shall be determined as follows:

(i) If the value of the decedent’s taxable estate is over $1,000,000 but not over 1,500,000, the tax owed to the commonwealth shall be 16 per cent of the excess over $1,000,000;
