XII. (5%) Remedios, a resident citizen, died on November 10, 2006. She died leaving three condominium units in Quezon City valued at P5 Million each. Rodolfo was her only heir. He reported her death on December 5, 2006 and filed the estate tax, he asked the Commissioner of Internal Revenue to give him one year to pay the estate tax due. The Commissioner approved the request for extension of time provided that the estate tax be computed on the basis of the value of the property at the time of payment of the tax. Does the Commissioner of Internal Revenue have the power to extend the payment of estate tax? If so, what are the requirements to allow such extension? Does the condition that the basis of the estate tax will be the value at the time of the payment have legal basis? Reason briefly.
