The Massachusetts Alimony Reform Act for High Earners: Why a Divorce Financial Planner Treats the Guidelines as a Starting Point

The 30 to 35 percent formula in the Massachusetts Alimony Reform Act gets quoted in nearly every initial divorce consultation. Couples often arrive at their first meeting with a divorce financial planner expecting that figure to settle the alimony question. For households well inside the median income range with no complicating factors, that expectation is sometimes close to accurate. For high-earning couples in eastern Massachusetts, the statutory presumption is the beginning of the analysis, not the end of it. The combination of recent case law, the loss of alimony tax deductibility, and the structural features of upper-bracket compensation has made the real number a question that no calculator can answer on its own.

Understanding why the guidelines are a starting point matters because settlements built on the bare formula often fail to account for the factors that drive the actual outcome in cases above the median.

What the Statute Actually Says

Chapter 208, Section 53(b) of the Massachusetts General Laws provides that alimony generally should not exceed the recipient’s need or 30 to 35 percent of the difference between the parties’ gross incomes, whichever is less. The duration of general term alimony is capped by the length of the marriage: 50 percent of the months married for unions of five years or fewer, 60 percent for marriages between five and ten years, 70 percent for marriages between ten and fifteen years, 80 percent for marriages between fifteen and twenty years, and potentially indefinite for marriages longer than twenty years.

The statute also lists deviation factors under Section 53(e) that allow courts to depart from these presumptions: health and age of either party, tax considerations, health insurance costs, life insurance costs the payor is required to carry, unearned income from assets not allocated in the property division, periods of cohabitation or separation, and a residual category for any other factor the court finds relevant and material.

For couples at or near the income brackets where the guideline was drafted with in mind, the formula often produces a reasonable answer. For couples well above those brackets, the deviation factors and the case law interpreting them do more work than the formula itself.

The Tax Treatment Change Disrupted the Math

The Tax Cuts and Jobs Act eliminated the federal deduction for alimony payments made under divorce or separation agreements executed after December 31, 2018. Massachusetts conformed to this treatment for state tax purposes for tax years 2022 and after. Alimony is no longer deductible by the payor or includible in the recipient’s income for either federal or Massachusetts tax purposes.

This change affects high earners disproportionately. Under the pre-2019 rules, an alimony payor in the top federal bracket plus Massachusetts state tax could recover roughly 40 percent or more of every alimony dollar through tax savings. The 30 to 35 percent figure in the statute was calibrated against that backdrop. Without the deduction, the after-tax cost of paying alimony at the same gross level is substantially higher than the figure that produced the original formula.

Courts have not formally rewritten the percentage, but the loss of deductibility has changed how the formula gets applied in practice. After-tax analysis is no longer optional in upper-income cases.

How Cavanagh Changed the Analysis

The Supreme Judicial Court’s 2022 decision in Cavanagh v. Cavanagh introduced a mandatory framework for cases involving both alimony and child support. Judges must calculate alimony first based on the statutory factors, then calculate child support using post-alimony incomes. They must then start over by calculating child support first using the parties’ pre-alimony incomes, then determine whether alimony is appropriate from any remaining income. The court compares the after-tax results of both approaches and selects whichever produces the most equitable outcome.

For high earners with combined incomes well above the Massachusetts Child Support Guidelines threshold (now $400,000 combined), this two-track analysis can produce materially different results depending on which sequence the court applies. Modeling both scenarios with the actual tax consequences is now part of any responsible settlement analysis.

The 2024 decision in Openshaw v. Openshaw added another layer. The court held that if a couple had a consistent habit of saving during the marriage, the recipient’s ability to maintain that savings pattern can be considered as part of “need” for alimony purposes. In high net worth households where significant savings were a fixed feature of the marital lifestyle, this expands the analytical universe well beyond bare living expenses.

Why Cash Flow Modeling Becomes the Center of the Negotiation

In cases at or below the guideline range, the formula provides a defensible answer most parties can accept. In high net worth cases, the formula is one input into a much larger picture that includes:

• Bonus income, RSU vesting, and other variable compensation that may not be reflected accurately in a single year of W-2 income
• Investment income from assets allocated in the property division
• The post-divorce tax position of each spouse, which can differ significantly from the joint filing position the couple has been in
• Anticipated retirement timing, which under the Alimony Reform Act allows the payor to seek termination of general term alimony upon reaching full retirement age
• Health insurance, life insurance, and the cost of replacing benefits previously provided through employer plans

A divorce financial planner working as financial neutral builds cash flow projections that show what each spouse’s household looks like at 5, 10, and 20 years out under different alimony structures. These projections are analytical tools built on stated assumptions, not predictions of what will actually happen. Their value is in making the long-term implications of settlement options visible while there is still time to choose among them.

For longer marriages, the projections often run past the alimony termination date. A 25-year marriage with general term alimony potentially ending at the payor’s retirement raises real questions about what the recipient’s financial picture looks like after that point. Those questions belong in the negotiation now, not in a modification proceeding years later.

Building a Number Both Spouses Can Sustain

The statutory formula gives the parties and the court a presumptive ceiling. The case law gives the court tools to deviate when the facts call for it. The financial analysis fills in what the numbers actually mean for the two households that will exist after the divorce closes. Working with an experienced divorce financial planner who has handled high-income alimony cases in the Massachusetts collaborative process means the modeling underlying the negotiation reflects the current state of the law and the actual financial picture of the household. If your case involves variable compensation, significant investment assets, or a long marriage with a substantial income gap, getting that analysis on paper before settlement discussions deepen tends to produce a more durable outcome.
