There is no set dollar amount of back child support that automatically becomes a felony in Massachusetts. State law treats any willful failure to pay a court-ordered obligation as a potential felony when the parent had the ability or earning capacity to pay.1General Court of Massachusetts. Massachusetts Code Chapter 273 – Section 1 A separate federal law does set a hard number: owing more than $10,000 in support for a child who lives in another state is a federal felony.2Office of the Law Revision Counsel. 18 USC 228 – Failure to Pay Legal Child Support Obligations So even a modest balance can trigger felony exposure in Massachusetts if a judge finds you deliberately refused to pay.
Massachusetts Has No Dollar Threshold
Under Massachusetts General Laws Chapter 273, Section 1, a parent commits a felony by willfully failing to obey a court-ordered support obligation while having the financial ability or earning capacity to comply, or by leaving Massachusetts without making reasonable provision for a spouse’s or child’s support.1General Court of Massachusetts. Massachusetts Code Chapter 273 – Section 1
The word “willfully” is what the case turns on. Prosecutors have to prove you had the money, or the ability to earn it, and chose not to pay. Courts look at bank statements, spending patterns, employment history, and whether you made any effort to pay even something. A parent who lost a job and genuinely cannot afford payments is in a different position than one working off the books, hiding assets, or making discretionary purchases while claiming poverty.
Because the statute hinges on willfulness rather than a number, there is no safe amount of arrears. A parent $2,000 behind who clearly could have paid faces the same legal exposure as one $50,000 behind. The question is whether you chose not to pay, not how much you owe.
State Felony Penalties
Willful failure to pay while remaining in Massachusetts carries up to five years in state prison, a fine of up to $5,000, or both. A shorter sentence of up to two and a half years in a county jail or house of correction is also possible.3General Court of Massachusetts. Massachusetts General Laws Chapter 273 – Section 15A
Leaving Massachusetts to avoid paying is treated more harshly. That offense carries up to ten years in state prison, a fine of up to $10,000, or both, with a county-level sentence of up to two and a half years as an alternative.3General Court of Massachusetts. Massachusetts General Laws Chapter 273 – Section 15A These penalties are on top of the arrears themselves. A conviction does not erase the debt.
The Federal Threshold: $10,000 or Two Years
If your child lives in a different state, 18 U.S.C. ยง 228 adds a federal track with actual numbers attached.
The offense is a federal misdemeanor when the debt exceeds $5,000 or has gone unpaid for more than one year. The maximum penalty is six months in prison.2Office of the Law Revision Counsel. 18 USC 228 – Failure to Pay Legal Child Support Obligations
It becomes a federal felony when the debt exceeds $10,000 or has gone unpaid for more than two years, with a maximum of two years in federal prison.2Office of the Law Revision Counsel. 18 USC 228 – Failure to Pay Legal Child Support Obligations Traveling across state lines or internationally to avoid a support obligation that meets the one-year or $5,000 threshold is also a felony with the same two-year maximum.4Department of Justice. Citizen’s Guide to U.S. Federal Law on Child Support Enforcement Courts also order mandatory restitution of the full unpaid balance on top of any prison time.
Federal prosecution is relatively rare and generally reserved for large arrears with clear interstate flight or concealment. But if you owe support in Massachusetts and your child has moved to another state, both statutes can apply.
What Usually Happens Before Criminal Charges
Criminal prosecution sits at the end of a long enforcement road. Long before charges are filed, the Department of Revenue (DOR) uses administrative tools that reach your paycheck, bank accounts, tax refunds, lottery winnings, unemployment and workers’ compensation benefits, and retirement funds.5General Court of Massachusetts. Massachusetts Code Chapter 119A – Section 6 Wage withholding is built into every support order unless a judge suspends it.6Massachusetts Department of Revenue.

Massachusetts can also revoke, suspend, or refuse to renew your driver’s license and professional licenses when you fall behind.5General Court of Massachusetts. Massachusetts Code Chapter 119A – Section 6 At the federal level, the State Department denies or revokes passports once arrears exceed $2,500.7Office of the Law Revision Counsel. 42 USC 652 – Duties of Secretary
The other pressure point is civil contempt in Probate and Family Court. The parent owed support, or the DOR itself, can file a Complaint for Contempt asking a judge to enforce the order.8Mass.gov. Probate and Family Court Complaint for Contempt (CJD 103) Civil contempt is not a criminal conviction, but a judge can order jail time to coerce payment. To find you in contempt, the court must determine there was a clear order, you clearly disobeyed it, and you had the ability to comply. If you genuinely cannot pay, you cannot be jailed, but the burden is on you to prove it. When jail is on the table, you have the right to an appointed attorney if you cannot afford one.
Why Waiting Makes Everything Worse
Two features of child support debt catch parents off guard.
The DOR charges interest and penalties on any past-due balance above $500, and those charges accrue monthly. A balance grows even when no new support comes due.
The bigger problem is federal: the Bradley Amendment bars any state from retroactively reducing child support arrears. Once a payment comes due and goes unpaid, it becomes a judgment by operation of law. No court, including a bankruptcy court, can erase it after the fact. The one narrow exception is that a modification can apply retroactively only to the date the other parent received notice of your modification petition. Everything that accrued before that date is locked in.
That is where willfulness and arrears intersect. Parents who lose a job or face a health crisis often assume the court will understand and wait months before doing anything. Each week of delay adds to a balance that cannot be reduced later, and the silence starts to look like a choice rather than a hardship.
File a Modification the Day Circumstances Change
If you cannot afford your current order, file a Complaint for Modification in Probate and Family Court showing a material change in circumstances such as involuntary job loss, long-term disability that reduces earning capacity, or a significant change in custody.9Mass.gov. Probate and Family Court Complaint for Modification You will need financial statements documenting the change.10Mass.gov. Instructions – Complaint for Modification
File the day your circumstances change, not weeks later. The court can only reduce support back to the date the other parent was notified of your filing, and everything before that stays owed in full. A prompt filing also cuts against a finding of willfulness. A judge deciding whether nonpayment was deliberate looks hard at whether you took steps to address the problem or simply let arrears build.
