Maryland Child Support in 2026 | Guerami Law Firm

Published June 1, 2026 on familylawmd.com

Few words frighten a parent more than “child support.” For the parent who pays, it can feel like a number that arrives from nowhere and never stops. For the parent who receives it, it can feel like a promise that never quite gets kept. Both fears are real. In Maryland, a wrongly calculated order can cost — or shortchange — a family thousands of dollars every year, and the price of getting it wrong is steep: wage garnishment, a suspended driver’s license, interest stacking on unpaid balances, and a debt that can now follow a parent past death.

But fear is not a plan. Maryland’s child support system is demanding, and in 2026 it has changed in ways that matter. Here is the honest picture — and the realistic path through it.

Child Support Belongs to the Child — Not to You

Start with the hardest truth, because it surprises good people every week: in Maryland, child support is the child’s right, not a bargaining chip between parents. On June 27, 2025, the Supreme Court of Maryland ruled in _In re Marriage of Houser_ that parents cannot agree to waive child support. Even a signed, notarized deal — “I’ll skip support if you take the house” — will not bind a court, because the right does not belong to the parent giving it up. If your separation plan quietly trades away your child’s support, expect a judge to undo it.

How the Number Is Built: The Income Shares Model

Maryland calculates support under Family Law § 12-204 using the “income shares” model. The idea is simple to say and hard to do well: the court estimates what both parents together would have spent on the child if the household had stayed intact, then splits that amount in proportion to each parent’s share of combined income. The state publishes a schedule running from $900 in combined monthly income all the way up to $30,000 per month — a ceiling raised from $15,000 effective July 1, 2022. At or below that ceiling, the guideline figure is presumed correct. Above it (more than $360,000 a year combined), the judge has discretion and may extrapolate from the schedule or weigh the family’s actual spending.

The fight is usually about what counts as “adjusted actual income.” Salary, wages, bonuses, commissions, self-employment profit, and many benefits go in; certain pre-existing support and alimony obligations come out. A parent with variable income — bonuses, tips, equity, a side business — is where errors and gamesmanship hide, and where careful proof changes the outcome.

Overnights Change Everything: The 92-Night Line

Custody and support are joined at the hip. When one parent has the children for most of the year, the court uses Worksheet A. But once each parent keeps the children at least 92 overnights a year — more than 25% of the time — the case moves to Worksheet B, the shared-custody formula, which can shift the obligation sharply. Between 92 and 109 overnights there is a transitional zone with its own adjustments. This is why a few nights a year on the calendar can be worth more than an argument about salary — and why you should never negotiate a parenting schedule without understanding what it does to the support number.

What’s New in 2025–2026

★ Key 2025–2026 Changes

Multifamily adjustment (effective Oct. 1, 2025, under HB 275 / SB 1038): a parent with a legal duty to support other children living in the home may deduct 75% of a theoretical support obligation for those children before the guideline runs. It applies only to new or modified orders entered on or after Oct. 1, 2025 — existing orders do not change automatically.
Driver’s license suspension reform (Oct. 1, 2025): the out-of-compliance window before the Child Support Administration notifies the MVA grew from 60 to 120 days, and parents earning under 250% of the federal poverty guidelines are shielded from suspension.
Estate priority: unpaid support is now a “preferred claim” against a deceased parent’s estate, paid ahead of most other creditors.
In re Marriage of Houser (June 27, 2025): child support cannot be waived by agreement.

Common, Costly Mistakes

⚠ Avoid these traps

Trading away support in a settlement. After _Houser_, a court can set your “deal” aside and order support anyway.
Self-help non-payment. Losing your job, a new baby, or a move does not lower your order by itself. Until a judge signs a new order, the old one runs — and arrears accrue interest.
Assuming the order auto-updates. Maryland orders do not adjust on their own. The new multifamily adjustment helps you only if you actually file to modify.
Hiding or shrinking income. Quit a job or work under the table and a judge can impute income as if you still earned it.
Ignoring notices from the Child Support Administration. Wage withholding, license actions, tax intercepts, and contempt all begin with a letter you should not throw away.

When and How to Change an Order

To modify support, you must show a material change of circumstances since the last order. As a practical benchmark, a change of about 25% in either parent’s income — up or down — is usually enough to warrant a review; smaller changes may qualify but are not guaranteed. A real shift toward shared custody (crossing the 92-overnight line) can also trigger a new calculation. The critical, often-painful detail: a modification generally reaches back only to the date you file, not to the day your life changed. Waiting costs money you cannot recover.

If You Are Owed Support

Maryland gives the receiving parent real enforcement tools through the Child Support Administration and the courts: automatic wage withholding, interception of tax refunds and lottery winnings, liens, license suspension (now on the 120-day timeline), the new estate priority, and contempt proceedings that can carry the threat of jail for willful refusal to pay. Enforcement works best when the order is precise and the record is clean — which, again, comes back to getting the number and the paperwork right.

The Path Forward

The parents who get fair results are rarely the lucky ones — they are the ones whose income was proven accurately, whose overnights were counted honestly, and whose motions were filed on time.

You are not powerless, and you are not alone in this. The same system that feels punishing when it is used against you becomes a shield when it is used correctly for you. Maryland’s guidelines look like a fill-in-the-blank form. They are not. The overnights, the income rules, the 2025 adjustments, and the worksheets interact in ways that move thousands of dollars and shape years of your child’s life. Treat the calculation with the seriousness it deserves, and get experienced help before you sign anything.
