Any such person may, on or before the deadline for an application for exemption under section 59, apply to the board of assessors for an exemption of such real property from taxation during such year; provided, however, that in the case of real estate owned by a person jointly or as a tenant in common with a person not such person's spouse, the exemption shall not exceed that proportion of total valuation which the amount of such person's interest in such property bears to the whole tax due. The board of assessors may grant such exemption provided that the owner or owners of such real property have entered into a tax deferral and recovery agreement with the board of assessors on behalf of the city or town. The agreement shall provide:—

(1) that no sale or transfer of such real property may be consummated unless the taxes which would otherwise have been assessed on such portion of the real property as is so exempt have been paid, with interest at the rate of 8 per cent per annum or such lesser rate as may be determined by the legislative body of the city or town, subject to its charter, not later than the beginning of the fiscal year to which the tax relates;

Any additional taxes deferred, plus interest, on said real property under a tax deferral and recovery agreement signed by a surviving spouse shall be added to the taxes and interest which would otherwise have been due, and the payment of which has been postponed during the life of such surviving spouse, in determining the 50 per cent requirement of clause (2);

(4) that if the taxes due, plus interest, are not paid by the heir-at-law, assignee or devisee or if payment is not postponed during the life of a surviving spouse, such taxes and interest shall be recovered from the estate of the owner; and

(5) that any joint owner or mortgagee holding a mortgage on such property has given written prior approval for such agreement, which written approval shall be made a part of such agreement; and

(6) that the tax deferral and recovery agreement shall not exceed 3 tax years, that the total amount of the taxes due, plus interest, shall be paid in 5 equal payments over a 5–year period, and that the first payment shall be due 2 years after the last day of the tax deferral.

In the case of each tax deferral and recovery agreement entered into between the board of assessors and the owner or owners of such real property, the board of assessors shall forthwith cause to be recorded in the registry of deeds of the county or district in which the city or town is situated a statement of their action which shall constitute a lien upon the land covered by such agreement for such taxes as have been assessed under this chapter, plus interest as provided hereinafter.

A lien filed pursuant to this section shall be subsequent to any liens securing a reverse mortgage, excepting shared appreciation instruments. The statement shall name the owner or owners and shall include a description of the land adequate for identification. Unless such a statement is recorded the lien shall not be effective with respect to a bona fide purchaser or other transferee without actual knowledge of such lien. The filing fee for such statement shall be paid by the city or town and shall be added to and become a part of the taxes due.

In addition to the remedies provided by this clause, the recorded statement of the assessors provided for in this clause shall have the same force and effect as a valid taking for nonpayment of taxes under the provisions of section 53 of chapter 60, except that: (1) interest shall accrue at the rate provided in this clause until the conveyance of the property or the death of the person whose taxes have been deferred, after which time interest shall accrue at the rate provided in section 62 of said chapter 60; (2) no assignment of the municipality's interest under this clause may be made pursuant to section 52 of said chapter 60; (3) no petition under section 65 of said chapter 60 to foreclose the lien may be filed before the expiration of 6 months from the conveyance of the property or the death of the person whose taxes have been deferred.

Nineteenth, Merchandise, machinery and animals owned by inhabitants of this commonwealth but situated in another state.

Where a portion of the real property occupied as a domicile of an applicant under this clause is located within a municipality other than the municipality in which the applicant is domiciled, and where the value of said property, or the taxes, assessed by the municipality in which such applicant is domiciled would result in his receiving less than the maximum exemption provided by this clause, that part of the property of such applicant within such other municipality shall be exempt to a value, or to an amount of tax, sufficient to grant the applicant the total maximum exemption provided by the clause. Any person who receives an exemption under the provisions of this clause shall not receive an exemption on the same property under any other provision of this section except clause Eighteen.

Any amount of money annually appropriated by the commonwealth for the purpose of reimbursing cities and towns for taxes abated under this clause, clause Forty-first B, clause Forty-first C, and clause Forty-first C1/2 shall be distributed as hereinafter provided.

(1) has so owned and occupied as his domicile such real property or other real property in the commonwealth for five years; or

(2) is a surviving spouse who inherits such real property and has occupied such real property or other real property in the commonwealth as his or her domicile for five years and who otherwise qualifies under this clause; and provided further that such person, and such person and his spouse, if married, had, during the preceding year, gross receipts from all sources not in excess of twenty thousand dollars. Any city or town may also, by vote of its legislative body, adopt a higher maximum qualifying gross receipts amount for the purposes of this section; provided, however, that such maximum qualifying gross receipts amount shall not exceed the amount of income determined by the commissioner of revenue for the purposes of subsection (k) of section 6 of chapter 62, for a single person who is not a head of household.

In determining the total period ownership of an applicant for exemption under this clause, the time during which the same property was owned by a husband or wife individually shall be added to the period during which such property was owned by said husband and wife jointly. In computing the gross receipts of such an applicant or of such an applicant and his spouse, if married, ordinary business expenses and losses may be deducted but not personal and family expenses.

[Introductory paragraph of third paragraph of clause Forty-first A effective for taxes assessed for fiscal years beginning on or after July 1, 2016. See 2016, 218, Sec. 247.]

Any such person may, on or before the deadline for an application for exemption under section 59, apply to the board of assessors for an exemption of such real property from taxation during such year; provided, however, that in the case of real estate owned by a person jointly or as a tenant in common with a person not such person's spouse, the exemption shall not exceed that proportion of total valuation which the amount of such person's interest in such property bears to the whole tax due. The board of assessors shall grant such exemption provided that the owner or owners of such real property have entered into a tax deferral and recovery agreement with said board of assessors on behalf of the city or town. The said agreement shall provide:

(1) that no sale or transfer of such real property may be consummated unless the taxes which would otherwise have been assessed on such portion of the real property as is so exempt have been paid, with interest at the rate of eight per cent per annum or such lesser rate as may be determined by the legislative body of the city or town, subject to its charter, no later than the beginning of the fiscal year to which the tax relates;

(2) that the total amount of such taxes due, plus interest, for the current and prior years does not exceed fifty per cent of the owner's proportional share of the full and fair cash value of such real property;

(3) that upon the demise of the owner of such real property, the heirs-at-law, assignees or devisees shall have first priority to said real property by paying in full the total taxes which would otherwise have been due, plus interest; provided, however, if such heir-at-law, assignee or devisee is a surviving spouse who enters into a tax deferral and recovery agreement under this clause, payment of the taxes and interest due shall not be required during the life of such surviving spouse. Any additional taxes deferred, plus interest, on said real property under a tax deferral and recovery agreement signed by a surviving spouse shall be added to the taxes and interest which would otherwise have been due, and the payment of which has been postponed during the life of such surviving spouse, in determining the fifty per cent requirement of subparagraph (2);

(5) that any joint owner or mortgagee holding a mortgage on such property has given written prior approval for such agreement, which written approval shall be made a part of such agreement.

In the case of each tax deferral and recovery agreement entered into between the board of assessors and the owner or owners of such real property, said board of assessors shall forthwith cause to be recorded in the registry of deeds of the county or district in which the city or town is situated a statement of their action which shall constitute a lien upon the land covered by such agreement for such taxes as have been assessed under the provisions of this chapter, plus interest as hereinafter provided. A lien filed pursuant to this section shall be subsequent to any liens securing a reverse mortgage, excepting shared appreciation instruments. The statement shall name the owner or owners and shall include a description of the land adequate for identification. Unless such a statement is recorded the lien shall not be effective with respect to a bona fide purchaser or other transferee without actual knowledge of such lien.

This clause shall take effect in any city or town upon its acceptance by such city or town for fiscal years commencing on or after July first, nineteen hundred and eighty-six, or for fiscal years commencing on or after such later July first as the city or town may elect.
