A collection agency is a company that pursues payment on debts the original creditor could not collect on its own. Once an account goes to collections, the agency either works the debt on commission for the creditor or buys the account outright and becomes your new creditor. From that point on, the agency is who contacts you, who negotiates with you, and who can report the debt to the credit bureaus or sue you over it. Federal law gives you specific rights in that relationship, and knowing them changes what a collector can actually do.
Who the Agency Actually Works For
Collection agencies run on two very different business models, and the difference matters because it changes who owns the debt.
In a contingency arrangement, the agency collects on behalf of the original creditor and earns a percentage of what it recovers. Industry commissions generally run 25% to 50%, with older accounts commanding higher fees. The creditor still owns the debt. If the agency collects nothing, it earns nothing, which is why contingency collectors tend to be persistent.
Debt buyers work differently. They purchase delinquent accounts in bulk for a fraction of the original balance, sometimes just a few cents on the dollar. Once the sale closes, the buyer legally owns the debt and keeps every dollar it recovers. You no longer owe the original company at all. Any payment, dispute, or settlement goes through the buyer, because the buyer is now your creditor.
How Debt Ends Up With a Collector
Almost any unpaid obligation can be sent to collections. Credit card debt and medical bills account for a large share of consumer collections, with utility bills, personal loans, auto deficiencies, and gym memberships regularly in the mix. Creditors typically wait 90 to 120 days of nonpayment before transferring an account, though the exact timeline varies.
Medical debt is treated somewhat differently. In 2023, the three national credit bureaus voluntarily stopped reporting medical debts under $500 and removed medical collections that had already been paid. Larger unpaid medical bills can still appear on your credit report. If a medical collection shows up on yours, check whether it falls below that threshold before anything else.
How a Collector First Reaches You
Contact almost always starts in the mail. Within five days of first contacting you, the agency must send a validation notice containing specific details about the debt: the amount owed, the name of the creditor, and instructions for disputing the balance.1eCFR. 12 CFR 1006.34 – Notice for Validation of Debts The notice also includes a tear-off response form you can use to challenge the debt or request information about the original creditor.
If you don’t respond, phone calls follow, to a home number, cell phone, and sometimes by email or text. When your contact information is outdated, agencies use skip tracing, cross-referencing public records and credit bureau data to find your current address and phone number. That is how collectors reconnect with people who have moved.
Your Rights Under Federal Law
The Fair Debt Collection Practices Act, codified at 15 U.S.C. ยง 1692, sets the ground rules for how third-party collectors can interact with you.2Office of the Law Revision Counsel. 15 USC 1692 – Congressional Findings and Declaration of Purpose The law covers third-party agencies and debt buyers. It generally does not cover an original creditor collecting its own debts, which is a boundary worth noting if your account hasn’t actually been handed off yet.
Contact Limits
Collectors cannot call at unreasonable times. Federal rules limit contact to between 8:00 a.m. and 9:00 p.m. in your local time zone. They cannot contact you at work if your employer prohibits it. Calling repeatedly to harass you, threatening violence, or misrepresenting what you owe all violate the law.
The Right to Dispute
After receiving the validation notice, you have 30 days to dispute the debt in writing. If you do, the collector must stop all collection activity on the account until it sends verification, which could be documentation from the original creditor or a copy of a court judgment. This is one of the most underused protections consumers have. If something looks wrong, an inflated balance, an account you don’t recognize, a debt you already paid, dispute it in writing within that window. The collector has to prove the debt is legitimate before it can keep pursuing you.
The Right to Stop Contact
You can send a written request telling the collector to stop communicating with you. Once the agency receives it, the agency must comply, with narrow exceptions: it can contact you one more time to confirm it is stopping collection efforts, or to notify you that it intends to take a specific legal action like filing a lawsuit.3eCFR. Part 1006 – Debt Collection Practices (Regulation F) A cease-communication letter does not erase the debt. The collector can still sue you and still report the account to the credit bureaus. The phone calls and letters stop.
What Happens If You Don’t Pay
Ignoring a collection does not make it disappear, and the consequences escalate.
Credit Reporting
Collection agencies routinely report unpaid accounts to Equifax, Experian, and TransUnion. A collection entry can significantly lower your score, which makes it harder to qualify for loans, apartments, and sometimes jobs. The entry can remain on your report for up to seven years from the date you first missed a payment to the original creditor.4Equifax. Collection Accounts and Your Credit Scores Paying the collection later may update the status, but it will not pull the entry off your report before that seven-year window closes.
Lawsuits and Garnishment
If a collector sues you and wins, or you simply don’t respond to the lawsuit, the court enters a judgment against you. A judgment unlocks wage garnishment and bank account levies. For ordinary consumer debts, federal law caps garnishment at 25% of your disposable earnings, and no garnishment is allowed if your weekly disposable income falls below 30 times the federal minimum wage.5U.S. Department of Labor. Fact Sheet #30 – Wage Garnishment Protections of the Consumer Credit Protection Act Some states impose stricter limits, and a few prohibit garnishment for consumer debt entirely.
The biggest mistake people make at this stage is ignoring the lawsuit. If you don’t respond, the court typically enters a default judgment, and you lose the chance to challenge the debt’s validity, the amount, or whether the statute of limitations has already expired.
The Statute of Limitations Trap
Every debt has a statute of limitations, a window during which a collector can sue. For most consumer debts, that period runs three to ten years depending on the state and the type of debt. Once it closes, the debt is “time-barred,” and federal regulations prohibit the collector from suing you or threatening to sue.6eCFR. 12 CFR 1006.26 – Collection of Time-Barred Debts
The trap: in many states, making even a small payment on a time-barred debt, or acknowledging it in writing, can restart the clock. A debt the collector could no longer sue on becomes legally enforceable again. If a collector contacts you about a very old account, confirm where the statute of limitations stands before you agree to anything or send any money.
Settling With a Collector
Collectors have room to negotiate, especially debt buyers who paid pennies on the dollar for your account. Lump-sum settlements are common, and depending on the age and type of the debt, you may be able to resolve the balance for substantially less than what you owe. Credit card debts and medical bills tend to be particularly negotiable once they’ve been in collections for a while. A one-time payment gives you more leverage than a payment plan.
Get the settlement in writing before you send money. The letter should confirm the settled amount, state that the payment satisfies the debt in full, and specify how the collector will report the account to the credit bureaus. Verbal promises are worth nothing if the account is later resold or the agency disputes what was agreed.
The Tax Bill After a Settlement
When a creditor or collector forgives $600 or more of what you owe, federal law requires them to report the canceled amount to the IRS on Form 1099-C.7Internal Revenue Service. About Form 1099-C, Cancellation of Debt The IRS treats the forgiven amount as taxable income. Settle a $10,000 debt for $4,000 and you may receive a 1099-C for the $6,000 difference and owe tax on it.
There is an important exception. If your total liabilities exceeded the fair market value of your total assets immediately before the cancellation, you were insolvent, and you can exclude some or all of the canceled debt from your income. You claim the exclusion by filing Form 982 with your tax return and calculating the amount by which you were insolvent.8Internal Revenue Service. Publication 4681 – Canceled Debts, Foreclosures, Repossessions, and Abandonments Many people in debt trouble qualify without realizing it, so run the numbers before assuming you’ll owe tax on a settlement.
When the Collector Breaks the Rules
The FDCPA gives you a private right of action, so you can sue a collector that violates the law without waiting for a regulator. If you win, you can recover actual damages, additional statutory damages of up to $1,000, and reasonable attorney’s fees.9Office of the Law Revision Counsel. 15 USC 1692k – Civil Liability In class actions, courts can award up to $500,000 or 1% of the collector’s net worth, whichever is less.
The attorney’s fees provision is what makes these cases viable. Because the collector has to pay your lawyer if you win, consumer attorneys regularly take FDCPA cases on contingency. Common violations include calling outside permitted hours, failing to send a proper validation notice, threatening legal action the collector has no intention of taking, and continuing to contact you after receiving a written cease-communication request. Keep the voicemails, the letters, and the call logs. That record is what turns a violation into a case.
