In Massachusetts, “income” for child support is defined broadly. It includes salary and wages, self-employment earnings, commissions, bonuses, and in many cases overtime and a second job, along with a number of sources parents do not expect. The Guidelines cast a wide net on purpose, so the support figure reflects a parent’s real ability to contribute, not just the number on a pay stub.
Income is the single largest driver of a child support order, and it is the input that generates the most disagreement in a divorce. Get it right and the rest of the calculation follows. Get it wrong, and the order is built on a number that was never accurate to begin with.
Greco Law is a Woburn divorce firm, and establishing the true income picture is part of how we protect a client through the whole of a divorce, not a side issue handled at the end. Here is how Massachusetts defines the income that feeds a child support order.
The Guidelines Define Income Broadly
The Massachusetts Child Support Guidelines start from a wide definition of gross income. The goal is to capture what a parent actually earns and has available, from whatever source, before the worksheet does its work. That breadth is deliberate. A narrow definition would be easy to work around, so the Guidelines reach across categories of earnings and many forms of recurring benefit.
For a salaried employee with a single, steady paycheck, this is usually straightforward. The complexity, and the disputes, arise when income comes from more than one place or is structured in a way that obscures its true size.
What Is Clearly Counted
Some categories are rarely in question. These are treated as income in nearly every case:
- Salary, wages, and tips
- Commissions and bonuses
- Overtime and income from a second job, in many circumstances
- Self-employment and business income
- Income from rental property
- Pensions, annuities, and many retirement distributions
- Unemployment benefits and certain other government benefits
- Interest and dividends
The presence of variable pay, such as bonuses and commissions, is often where the first real disagreement appears. How a fluctuating bonus history is averaged and presented can move the figure meaningfully, which is why the way this evidence is assembled matters.
The Sources People Miss
The harder work is in the income that does not arrive as an ordinary paycheck. In a divorce involving any financial complexity, these are the areas we examine closely:
- Perks and benefits that function as income. A car, housing, or regular expenses paid on a parent’s behalf can carry real value.
- Business income that stays inside the business. Retained earnings and distributions run through a company can understate what an owner truly earns. Our post on child support for self-employed and business-owner parents looks at this in depth.
- Deferred and equity compensation. Stock, options, and deferred pay are part of the financial picture even when they are not showing up on this year’s W-2.
- Irregular or seasonal income. Work that pays in uneven cycles still counts, and it has to be presented fairly across the year.
The same careful income analysis that gets a child support number right also drives the alimony figure and informs the division of property. In a well-run divorce, this work is done once and used everywhere.
When a Parent Underreports or Is Not Working
Two situations call for a different kind of attention.
The first is underreporting. When a parent’s stated income does not match their lifestyle or their financial records, the true figure has to be established through documentation rather than accepted at face value. This is a matter of evidence, not accusation.
The second is a parent who is not working or is working below their capacity. Massachusetts allows a court to attribute income to a parent who is capable of earning more than they currently do, based on their earning ability, work history, and the opportunities available to them. We make that argument when the facts support it, and we defend against an unfair attribution when they do not.
How Income Feeds the Worksheet
Once each parent’s income is established, it flows into the Child Support Guidelines worksheet alongside the parenting schedule and the cost of health insurance and child care. Our companion article on how child support is calculated in Massachusetts walks through that mechanism step by step. The point worth holding onto is simple: the worksheet is only as accurate as the income figures behind it, so the income analysis is where the real work lives.
| Income category | Usually counted? | Where disputes arise |
|---|---|---|
| Salary and wages | Yes | Rarely |
| Bonuses and commissions | Yes | Averaging a variable history |
| Business and self-employment income | Yes | Retained earnings, add-backs |
| Perks and paid expenses | Often | Establishing their value |
| Deferred and equity compensation | Considered | Timing and valuation |
The table above is a general guide to how income is approached. It is not a determination of what will count in any particular case.
The Documents That Establish Income
An income figure is only as sound as the records behind it, so a serious analysis begins with the paper. In most cases, the starting set includes recent pay stubs, the last several years of W-2 forms, and complete federal and state tax returns with their schedules. For a parent whose earnings run through a business or a partnership, the picture widens to include K-1 statements, 1099s, and the underlying business returns, which often tell a different story than a personal return alone.
Two documents deserve particular mention. Each party in a Massachusetts family case files a sworn financial statement with the court, a signed disclosure of income, assets, expenses, and liabilities that carries the weight of an oath. That statement, read against the tax returns and pay records, is frequently where a discrepancy first appears. The point of gathering these records together is not volume for its own sake. It is pattern. A single year can be misleading, but several years of returns, statements, and pay records read side by side tend to reveal what a parent genuinely earns, including whether a strong year was an outlier or the norm and whether a recent drop is real or arranged.
When Income Has to Be Attributed
A separate problem arises when a parent appears to be earning less than they could. Where a parent is unemployed or working below their capacity, Massachusetts allows a court to consider what that parent is able to earn, not only what they currently bring in. This is generally described as attributing income, and it is meant to keep a parent from lowering a support obligation by choosing to earn less.
Earning capacity is argued from the record rather than assumed. A court will typically look at a parent’s work history, education, training, recent earnings, and the opportunities that appear to be available in their field and area. The question is what this particular parent could reasonably earn, given who they are and what the market offers, not an abstract ideal. This cuts in both directions in a divorce. Where the facts suggest a parent has reduced their income by choice, we may press for income to be attributed. Where a reduction is genuine, a layoff, an illness, a downturn in an industry, we work to show that the lower figure reflects reality rather than avoidance. Whether attribution is appropriate depends heavily on the specific facts, and it is an area where careful presentation of the record tends to matter a great deal.
Serving Woburn and Middlesex County
Greco Law is based in Woburn and represents divorcing parents throughout Middlesex County, including Winchester, Stoneham, Reading, Burlington, Wakefield, Medford, and Melrose. These matters are heard at the Middlesex Probate and Family Court South in Woburn, where the accuracy of the income picture is often what the argument turns on.
Taking the Next Step
If child support is part of your divorce, the most useful first step is a confidential consultation. Bring what you have about both households’ finances, and we will show you how the income analysis is likely to play out and where it may be contested. Greco Law works with parents across Massachusetts, and where a number has been understated, we do the work to establish what a parent truly earns.
