How to Anonymously Report Someone for Child Support

To anonymously report someone for child support non-payment, contact the state child support enforcement agency in the state where the child or custodial parent lives, and submit what you know about the delinquent parent through the agency’s online tip form, phone hotline, or by mail. Every state runs an enforcement agency that accepts third-party information, and most let you leave your name out of it entirely. The federal Office of Child Support Services keeps a directory of every state and tribal office you can start from.¹

First, Make Sure There’s a Support Order to Enforce

Anonymous reporting only works when a court has already ordered someone to pay support and that person is failing to do so. If no order exists, there is nothing to enforce and nothing to report. In that situation, the custodial parent has to apply for services with their state child support agency, which can establish paternity if needed and get an order in place. Federal law requires every state to offer those services to anyone who applies.²

If an order does exist and the non-custodial parent is dodging payments, a third party can absolutely report it without giving their name.

Gather What You Know Before You Report

Vague tips with just a name tend to go nowhere. Enforcement staff need enough to locate and identify the person. Try to collect:

The parent’s full name, plus any aliases or maiden names.
A last known address, even an outdated one.
Employer name, address, and type of work. This matters most, because wage withholding is the single most effective collection tool.
Other income: cash jobs, freelance work, rental income, side businesses.
The children’s names and dates of birth, which help the agency match your tip to the right case.
The last four digits of the parent’s Social Security number, if you happen to know them.

You don’t need all of it. A full name paired with a current employer is often enough to trigger action. The more gaps you fill, the less legwork the agency has to do on its end.

Find the Right State Agency

Contact the enforcement agency in the state where the custodial parent or child lives, not where the non-custodial parent is hiding. The federal directory lists every state and tribal office with phone numbers, addresses, and website links.¹ The federal office itself doesn’t handle individual cases.

If the non-custodial parent lives in a different state from the child, don’t stall over which state to call. Federal law requires states to cooperate on interstate enforcement, and the office you contact will coordinate with its counterpart.

How to Submit the Report Without Giving Your Name

State agencies typically offer at least two of these three channels:

Online tip forms. Many state child support websites include a portal for submitting case information or tips. Some let you skip the name and contact fields entirely; others have a dedicated referral form.
Phone hotlines. When you call, say up front that you want to remain anonymous. The caseworker should be able to take your information without your identity.
Mail. Send a typed or handwritten letter with the details you’ve gathered. Leave off a return address, and drop it in a public mailbox rather than sending it from home or work.

For a parent who has fled across state lines to avoid paying, there is a separate federal channel. The HHS Office of Inspector General investigates those cases and accepts tips through an online form.³ For interstate flight cases, reporting to both the state agency and the OIG gives your tip the best chance of reaching the right investigators.

Reporting Hidden Income or Assets

Some of the most valuable tips involve a parent who is working under the table or hiding income to keep support payments artificially low. Enforcement agencies actively want that information.

Include as much concrete detail as you can: where the person works, what kind of work they do, the hours they keep, and any evidence their lifestyle doesn’t match what they claim to earn. Social media posts showing expensive purchases, vacations, or new vehicles are useful context. So are patterns of spending that don’t line up with reported income.

Courts can rely on indirect evidence. Even without a pay stub, a combination of lifestyle evidence, bank activity, and witness observations can show a parent is earning more than they’ve disclosed. If the agency finds enough to act on, it can pursue a modification of the support order based on actual earning capacity, or ask a court to hold the parent in contempt for deliberately evading their obligation.

What the Agency Can Do With Your Tip

Once your report comes in, enforcement staff check it against existing records. If the case is already open, your tip may fill in a missing employer or a current address. If it isn’t, the agency may open a preliminary review. Federal databases including the Federal Parent Locator Service let agencies cross-reference partial information against Social Security records, IRS data, and employment records to build out the picture.⁴ That’s why even a partial tip can matter.

From there, agencies have a serious toolkit. Wage withholding is the backbone: the employer is legally required to deduct support directly from the parent’s paycheck.⁵ Withholding can also reach unemployment benefits, workers’ compensation, Social Security, and veterans’ disability payments. States are also required to intercept state tax refunds, place liens on real and personal property, suspend driver’s, professional, and recreational licenses, report arrears to credit bureaus, and freeze bank accounts of delinquent parents. When arrears reach $2,500, the federal government can deny, revoke, or restrict the parent’s U.S. passport.⁶

In the most extreme cases, willfully failing to pay support for a child in another state can be prosecuted as a federal crime.⁷ These cases are rare compared to civil enforcement, but they exist for the worst offenders.

Because your report was anonymous, you won’t get updates. You won’t know if enforcement action was taken or if payments resumed. That’s the trade-off. If you later learn something new, like a new employer or a move, you can submit another anonymous tip.

How Your Identity Is Protected

Federal regulations impose strict confidentiality on every entity in the child support system. Social Security numbers, addresses, employment details, and financial information can’t be disclosed outside the program unless specifically authorized, and unauthorized disclosure carries civil monetary penalties.⁸ Those rules extend to tipster information. Agencies have no obligation to reveal where a tip came from and strong regulatory incentives not to. The same regulations include heightened protections for cases involving evidence of domestic violence or child abuse, requiring a family violence indicator on files where disclosure could put someone at risk.

No anonymity guarantee is absolute. If a case reached court, a judge could in theory order disclosure of information relevant to the proceedings. In practice this is very unlikely for a third-party tipster, because the tip itself isn’t the evidence used at trial. The agency investigates independently and builds its case from employment records, financial data, and other documentation. Your tip is the spark, not the proof.
