In the case of the estate of a nonresident transferor, when property is transferred by will or intestate laws, the net estate for the purpose of the tax imposed by the provisions of this chapter shall be ascertained by deducting from the gross taxable estate the following items: (a) Fees of the Connecticut Probate Court; (b) advertising expenses incidental to administration in this state; (c) the reasonable compensation of appraisers of real estate or tangible personal property situated within this state; (d) expenses incurred in connection with procuring the fiduciary‘s bond filed in the Connecticut Probate Court; (e) commissions paid in connection with the sale of real estate or tangible personal property situated within this state; (f) reasonable compensation of executors and administrators, qualifying as such in the Connecticut Probate Court, and reasonable fees for Connecticut attorneys; (g) the amount at the date of the transferor’s death of all unpaid mortgages upon real or tangible personal property situated within this state, which mortgages were not deducted in the appraisal of the property mortgaged; (h) unpaid taxes upon real or tangible personal property situated within this state which were a lien at the date of the transferor’s death; (i) any tax on untaxed property assessed by this state against the estate of the transferor; (j) special assessments which, at the date of death, were a lien on real property of the transferor situated within this state; (k) any amount exempted pursuant to subsection (b) of § 12-344. In case the domiciliary estate is insolvent, there shall be allowed as a deduction, in addition to the foregoing items, the amount by which the total of the lawful claims against and administration expenses of the estate, exclusive of Connecticut deductible items set forth above, exceeds the total value of property wherever situated subject to such claims and expenses, exclusive of the gross estate situated in this state. The foregoing deductions shall be allowed in the case of property transferred by will and by laws relating to intestate estates, provided they reduce the gross taxable estate. In the case of property transferred other than by will or by laws relating to intestate estates, such deductions shall be allowed (1) only to the extent that such property is includable in the decedent‘s gross taxable estate under the provisions of this chapter, and (2) only to the extent that the transferee has actually paid the deductible items and either the transferee was legally obligated to pay such items or the assets subject to probate are insufficient to pay such items.
