Massachusetts Alimony / Spousal Support Estimator

Massachusetts uses a statutory formula under Chapter 208, Section 53(b) of the Alimony Reform Act. Alimony generally cannot exceed the recipient's need or 30–35% of the difference between the spouses' gross incomes, whichever amount is less. Courts also weigh factors including marriage length, each spouse's income and employability, health, and contributions to the marriage. Income already allocated to child support is excluded from the alimony calculation.

Massachusetts recognizes four types of alimony under the Alimony Reform Act. General term alimony provides ongoing support with durational limits tied to marriage length. Rehabilitative alimony supports a spouse becoming self-sufficient, capped at 5 years. Reimbursement alimony compensates a spouse who funded the other's education or training during marriages of 5 years or fewer. Transitional alimony helps with lifestyle adjustment, limited to 3 years and non-modifiable.

Massachusetts imposes durational limits on general term alimony based on marriage length under Chapter 208, Section 53. Marriages of 5 years or fewer: alimony lasts up to 50% of the marriage. Marriages of 5–10 years: up to 60%. Marriages of 10–15 years: up to 70%. Marriages of 15–20 years: up to 80%. Only marriages exceeding 20 years may qualify for indefinite alimony. All general term alimony terminates when the payor reaches full Social Security retirement age.

Under Section 53(a) of the Alimony Reform Act, Massachusetts courts consider: the length of the marriage, age and health of both parties, income and employability of each spouse, economic and non-economic contributions to the marriage, the marital lifestyle, each party's ability to maintain that lifestyle, and lost economic opportunity resulting from the marriage. Courts may also impute income to an unemployed or underemployed spouse under Section 53(f).

General term and rehabilitative alimony can be modified upon showing a material change of circumstances under the Alimony Reform Act. Reimbursement and transitional alimony are non-modifiable. Cohabitation by the recipient with another person for 3 or more continuous months is grounds to suspend, reduce, or terminate general term alimony. If the cohabitation ends, alimony may be reinstated but cannot extend beyond the original termination date.

The Massachusetts Alimony Reform Act focuses primarily on financial factors rather than marital fault. While adultery remains a ground for divorce under Chapter 208, Section 1, it does not automatically bar or guarantee an alimony award. Courts prioritize economic need, income disparity, and marriage length when determining spousal support. However, if adultery caused financial harm — such as dissipation of marital assets — a judge may consider it as a relevant factor.

For divorce agreements executed after December 31, 2018, alimony is no longer tax-deductible for the payor or taxable income for the recipient under the federal Tax Cuts and Jobs Act of 2017. Massachusetts state tax treatment follows the same rule. This federal change effectively increased the real cost of alimony for payors and reduced the tax burden on recipients, which courts may factor into the 30–35% calculation under Section 53(b).

Massachusetts allows spouses to waive alimony rights in a valid prenuptial agreement under the Massachusetts Uniform Premarital Agreement Act, Chapter 209, Section 25. The agreement must be in writing, signed voluntarily by both parties, and each party should have independent legal counsel. Courts may still scrutinize the waiver if enforcing it would leave one spouse unable to support themselves, but properly drafted waivers are generally upheld.
