Every nonresident whose Massachusetts gross income, determined in accordance with section 5A of chapter 62, exceeds $8,000 or the personal exemption to which such nonresident may be entitled under section 3 of said chapter 62, whichever is the lesser, and every partnership, association or trust whose federal gross income, as defined in section 1 of said chapter 62, exceeds $100, shall make a return of such income.
Every individual, not otherwise required to file a return under this subsection, who is a resident for a portion of a 12-month period beginning on the first day of a taxable year and a nonresident for a portion of the same 12-month period and whose Massachusetts gross income, as defined in section 2 of chapter 62, exceeds $8,000 shall make separate returns as a resident and a nonresident of his income subject to taxation under said chapter 62.
A husband and wife may make a single return jointly of income taxes under chapter 62, even though one of the spouses has neither income nor deductions, provided that their taxable years begin on the same day and either end on the same day or on different days solely because of the death of either or both. Such return shall be known as a joint return and shall include the income, exemptions and deductions of both spouses. Each spouse shall be jointly and severally liable for the entire tax.
