Statute of Limitations on Debt by State 2026: The Complete Guide

Every state sets a time limit on how long collectors can sue you for debt. Once that clock runs out, the debt is time-barred -- but collectors can still try to collect. Know your rights, know your state's timeline, and protect yourself.

Published: April 11, 2026 · 18 min read

A debt collector calls you about a credit card you stopped paying six years ago. They sound authoritative. They mention a specific amount, a specific account, and they want you to pay. The letter they sent says "final notice" and references potential legal action. Your heart races. Do you owe this money? Can they actually sue you? And most importantly -- is there a law that might make this entire collection attempt meaningless?

There is. It is called the statute of limitations on debt, and it exists in every single state in the United States. The statute of limitations (often abbreviated as SOL) is a state law that sets a maximum time period during which a creditor or debt collector can file a lawsuit against you to collect a debt. Once that clock runs out, the debt becomes time-barred -- the collector cannot win a lawsuit to collect it, even if you genuinely owe the money.

This does not mean the debt disappears. Collectors can still call. They can still send letters. They can still ask you to pay. What changes is their legal leverage. Without the threat of a successful lawsuit, many collectors will accept pennies on the dollar -- or give up entirely if they realize you know your rights. Understanding the statute of limitations in your state is one of the most powerful pieces of debt defense knowledge you can have.

In this comprehensive guide, we will walk you through the full 50-state statute of limitations table for 2026, explain exactly what resets the clock, clarify what collectors can and cannot do after the SOL expires, and give you a step-by-step plan for handling collectors who pursue time-barred debt. If you are not sure whether a debt collector has the legal right to pursue you, start by sending a debt validation letter to demand proof of the debt and its current legal status.

The Short Version

The statute of limitations on debt ranges from 3 years (Mississippi, North Carolina, South Carolina, Tennessee) to 15 years (Rhode Island, Kentucky for some debts). The clock typically starts from your last payment or last account activity. Making a payment, acknowledging the debt, or signing a new agreement can restart the clock. After the SOL expires, collectors cannot successfully sue you, but they can still try to collect. Always respond to any lawsuit -- even for time-barred debt -- by raising the SOL as an affirmative defense.

What Is the Statute of Limitations on Debt?

The statute of limitations on debt is a state law that creates a deadline for creditors and debt collectors to file a lawsuit to collect a debt. Think of it as a timer that starts ticking from a specific event -- usually your last payment or the last activity on the account. Once that timer expires, the debt becomes time-barred, meaning the legal system will not enforce collection through a court judgment.

This concept exists for a practical reason: evidence degrades over time. Documents get lost. Memories fade. Witnesses move away. It becomes increasingly difficult for both the plaintiff and the defendant to mount a proper case as years pass. The statute of limitations ensures that legal disputes are resolved while evidence is still fresh and available.

Here is the critical point that most consumers do not understand: the statute of limitations varies by state and by type of debt. There is no single federal statute of limitations for consumer debt. Each state sets its own time periods, and many states have different SOL periods for different categories of debt -- written contracts, oral agreements, promissory notes, and open-ended accounts like credit cards. This is why two people with the same debt in different states can have completely different legal exposure.

It is also important to distinguish the statute of limitations from other debt-related timelines. The 7-year credit reporting period under the Fair Credit Reporting Act (FCRA) is a separate federal law that determines how long negative information can stay on your credit report. The statute of limitations and the credit reporting period run on different clocks, governed by different laws, and one does not affect the other. A debt can be time-barred (beyond the SOL) but still appear on your credit report, or it can fall off your credit report while still being within the statute of limitations period. For a deeper understanding of your credit reporting rights, see our guide on debt validation and the FDCPA.

How the Statute of Limitations Applies to Different Types of Debt

Not all debts are treated equally under the statute of limitations. States typically categorize debts into four types, each with its own SOL period. Understanding which category your debt falls into is essential for knowing your actual legal exposure.

Debt Type What It Covers Typical SOL Range
Written Contract Loans with signed agreements, auto loans, personal loans with written terms, mortgage deficiencies 4-15 years
Oral Agreement Verbal agreements to pay, informal loans between individuals 3-15 years
Promissory Note Signed promissory notes, some student loans, mortgage notes 5-15 years
Open-Ended Account Credit cards, lines of credit, revolving credit accounts, medical bills 3-10 years

Credit card debt -- the most common type of debt in collections -- is typically classified as an open-ended account in most states. This is because credit card agreements establish a revolving line of credit rather than a fixed loan with specific repayment terms. However, some states classify credit card debt under written contract law if there is a signed cardholder agreement. The classification matters because it can change the SOL period by several years.

Medical debt is usually treated as an open-ended account or written contract, depending on whether you signed a financial responsibility form at the healthcare provider. Personal loans with signed agreements are written contracts. Auto loan deficiencies (the remaining balance after a repo and auction) are typically written contracts. Understanding your debt type is the first step in determining whether a debt is time-barred.

Statute of Limitations on Debt by State 2026: Full 50-State Table

The following table shows the statute of limitations periods for each state as of 2026. These are the most current available figures, but state laws can change. The periods shown are for consumer debt -- different rules may apply to government debts, taxes, student loans, and other specialized categories.

Important: The SOL clock generally starts from the date of your last payment or last account activity -- whichever is more recent. This is known as the "date of default" or "date of last activity." If you made a $5 payment three years ago on an otherwise dormant account, the clock likely reset at that point.

States with the shortest SOL for credit card debt: Delaware (3 years), Maryland (3 years), Mississippi (3 years), North Carolina (3 years), and South Carolina (3 years). If you live in one of these states and have not made a payment or acknowledged a credit card debt in over 3 years, the debt is likely time-barred.

States with the longest SOL for credit card debt: Kentucky (10 years for open-ended, 15 years for written contracts), Louisiana (10 years), Rhode Island (10 years), Iowa (5 years for open-ended, 10 years for written contracts), Illinois (5 years for open-ended, 10 years for written contracts), Missouri (6 years for open-ended, 10 years for written contracts), and Wyoming (8 years for open-ended, 10 years for written contracts).

For the District of Columbia, the statute of limitations is 3 years for most consumer debts. Washington state has a 6-year SOL for credit card debt and most consumer obligations. If you moved states during the period when the debt was active, determining which state's SOL applies can be complicated -- generally, the SOL of the state where you currently reside or where the lawsuit is filed will apply, but this varies by jurisdiction.

What Resets the Statute of Limitations Clock?

This is the single most important section in this entire guide. The statute of limitations is not a fixed, unchangeable deadline. In every state, certain actions can reset the clock -- meaning the SOL period starts over from zero, giving the collector a fresh window of time to sue you. Understanding what resets the clock is essential because it is the difference between being legally protected and being legally exposed.

The following actions can restart the statute of limitations in most states:

1

Making a Partial Payment

This is the most common way the clock gets reset. Even a $5 payment on an old debt can restart the entire SOL period. The clock resets to the date of the payment, and the collector gets a brand-new window to sue you. This is why collectors are often eager to get you to agree to even a token payment on an old debt -- it revives their legal rights.

2

Acknowledging the Debt in Writing

Writing a letter, email, or even a text message to a collector that acknowledges you owe the debt can restart the clock. This includes statements like "I know I owe this debt," "I will pay when I can," or "I am trying to get the money together." Any written communication that admits the existence of the debt can be used as evidence that you acknowledged it, restarting the SOL period.

3

Making a Verbal Acknowledgment (in some states)

In some states, verbally acknowledging that you owe a debt on a recorded phone call can restart the SOL clock. Debt collectors record their calls for exactly this reason. If a collector gets you to admit on tape that you owe the money, they may be able to use that recording to reset the statute of limitations. This is why it is always safer to communicate with collectors in writing only.

4

Signing a New Payment Agreement or Promise to Pay

If you sign a new payment plan, settlement agreement, or even a "promise to pay" document, the clock resets completely. The collector now has a brand-new legal basis to pursue you -- the new agreement itself, which has its own statute of limitations period. Never sign anything with a debt collector without understanding the full legal implications.

5

Making a Charge on the Account

For open-ended accounts like credit cards, making a new charge (using the card) restarts the clock. If you have an old credit card account that you have not used in years, do not suddenly use it to make a small purchase -- that single charge can reset the entire SOL period for the entire balance on that account.

Critical Warning

Debt collectors know exactly how the statute of limitations works, and many actively try to get consumers to unknowingly reset the clock. They may call you about an old debt and use conversational techniques to get you to acknowledge the debt on a recorded line. They may offer a "small payment plan" that seems reasonable but actually revives their legal right to sue you for the full amount. Always be aware: if a debt is close to being time-barred, every interaction with a collector carries risk. When in doubt, communicate in writing only and consider consulting a consumer rights attorney before engaging.

The safest approach when dealing with an old debt that may be approaching the statute of limitations is to say as little as possible. If a collector contacts you, you can respond with a debt validation letter -- which is a request for information, not an acknowledgment of the debt. A properly written validation letter does not restart the SOL clock because it disputes the debt rather than admitting it.

What Collectors Can Still Do After the Statute of Limitations Expires

Here is where many consumers get confused. When the statute of limitations expires and the debt becomes time-barred, the debt does not disappear. The collector loses the ability to win a lawsuit against you, but they retain several other collection tools. Understanding what they can and cannot do is essential for managing your expectations and protecting yourself.

What Collectors CAN Still Do

Action Details
Continue calling and sending letters Collectors can legally continue to contact you about a time-barred debt. The FDCPA does not prohibit collection attempts on debts that are past the statute of limitations, as long as the collector does not make false or misleading statements.
Report the debt to credit bureaus As long as the debt is within the 7-year FCRA credit reporting period (measured from the date of first delinquency), the collector can report it to Equifax, Experian, and TransUnion. The statute of limitations and the credit reporting period are separate timelines.
Offer a settlement Collectors can propose a settlement on a time-barred debt. In fact, this is often when they are most willing to negotiate, because they know they cannot sue you. Settlements on time-barred debts are commonly available for 10-30% of the original balance.
File a lawsuit Collectors can file a lawsuit for a time-barred debt. The court will not automatically dismiss the case -- you must appear and raise the statute of limitations as an affirmative defense. If you fail to respond to the lawsuit, the collector can obtain a default judgment against you, which gives them legal collection tools again.
Sell the debt to another collector Time-barred debts are still bought and sold in the debt market. A new collector who purchases the debt inherits the same limitations -- they cannot successfully sue you, but they can attempt all other collection methods.

What Collectors CANNOT Do

Prohibited Action Why It Is Prohibited
Win a lawsuit to collect the debt If you raise the statute of limitations as a defense, the court must dismiss the case. The collector cannot obtain a judgment against you for a time-barred debt (unless you accidentally restart the clock).
Garnish your wages without a court judgment Wage garnishment requires a court judgment. Without a judgment (which they cannot get for a time-barred debt if you defend yourself), collectors cannot garnish your wages.
Seize your bank account without a judgment Bank levies require a court judgment. Time-barred debts do not give collectors the power to seize your assets without first winning in court.
Threaten legal action they cannot take Under the FDCPA, collectors cannot make false, deceptive, or misleading statements. Threatening to sue on a time-barred debt without disclosing that the debt is time-barred may violate the FDCPA. The CFPB has specifically stated that collectors must not mislead consumers about the legal enforceability of a debt.
Harass or abuse you The FDCPA prohibits harassment regardless of whether the debt is time-barred. This includes calling at unreasonable hours, using profane language, calling repeatedly with intent to annoy, or publishing your name on a "deadbeat list."

The most dangerous scenario is when a collector files a lawsuit on a time-barred debt and the consumer does not respond. If you ignore a lawsuit -- even one for a debt you know is time-barred -- the collector can get a default judgment against you. Once they have a judgment, they can garnish your wages, levy your bank account, and place liens on your property. The statute of limitations defense only works if you raise it in court. Never ignore a lawsuit.

Time-Barred Debt Rules: The FTC and CFPB Requirements

The Federal Trade Commission (FTC) and the Consumer Financial Protection Bureau (CFPB) have both addressed the issue of time-barred debt collection. While federal law does not prohibit collectors from attempting to collect time-barred debts, there are important rules and requirements they must follow.

CFPB Regulation F (Debt Collection Rule)

In November 2020, the CFPB issued its Debt Collection Rule (also known as Regulation F), which became effective in November 2021. This rule updated and modernized the FDCPA for the digital age. One of the most important provisions related to time-barred debt is the disclosure requirement.

Under Regulation F, when a collector communicates with you about a time-barred debt, they must either:

This is a critical consumer protection. If a collector contacts you about a debt that is past the statute of limitations and does not disclose this fact, they may be violating Regulation F. Any collector who threatens legal action on a time-barred debt without disclosing that they cannot legally win that lawsuit is potentially in violation of both the FDCPA and Regulation F.

State-Level Protections

Some states go even further than federal law. Several states have enacted laws that prohibit any collection activity on time-barred debts, including phone calls and letters. In these states, once the SOL expires, the collector must stop all contact. Check your state-specific consumer protection laws to see if your state provides this additional layer of protection. For a general overview of consumer rights against abusive collection practices, see our guide on what collection agencies can and cannot do.

Credit Reporting and Time-Barred Debt

A common misconception is that a time-barred debt automatically falls off your credit report. This is not true. The statute of limitations and the FCRA credit reporting period are two completely separate timelines:

It is entirely possible -- and common -- for a debt to be time-barred but still appear on your credit report. Conversely, a debt can fall off your credit report while still being within the statute of limitations period, meaning the collector could still sue you even though the debt no longer affects your credit score. The clock for the SOL and the clock for credit reporting both start from the date of your last activity or first delinquency, but they tick at different rates.

How to Handle Collectors Who Contact You About Old Debt

So a collector has contacted you about a debt you have not thought about in years. Your instinct might be to panic, call back, and try to resolve it. Instead, follow this step-by-step approach to protect yourself and make informed decisions.

1

Do Not Admit Anything or Make Any Payments

This is the most important rule. Do not say "I know I owe this," do not make even a small payment, and do not agree to anything on the phone. Any of these actions could restart the statute of limitations clock and give the collector a fresh legal window to sue you. Stay calm, say nothing about the debt itself, and move to step 2.

2

Request Written Communication Only

Tell the collector that you will only communicate in writing. This protects you from accidentally acknowledging the debt on a recorded phone call and gives you a paper trail of all communications. Under the FDCPA, you have the right to request that a collector stop calling you and communicate only by mail.

3

Send a Debt Validation Letter

Within 30 days of the collector's first written communication, send a debt validation letter demanding proof of the debt. A validation letter does not acknowledge the debt -- it disputes it -- so it does not restart the SOL clock. The letter should request: the original creditor's name, an itemized breakdown of the amount, proof of the collector's authority to collect, and the date of last activity on the account. Use our free debt validation letter generator to create a professional letter in under 60 seconds.

4

Calculate Whether the Debt Is Time-Barred

Using the state table above, determine the statute of limitations for your debt type in your state. Then calculate how many years have passed since your last payment or last activity on the account. If the elapsed time exceeds the SOL period, the debt is likely time-barred. Note the date carefully -- you may need it as evidence if the collector files a lawsuit.

5

Decide Your Response Strategy

If the debt is time-barred, you have several options: ignore the collector (they cannot sue successfully), send a letter stating the debt is time-barred and demanding they cease contact, or negotiate a settlement for a small fraction of the balance. If the debt is still within the SOL period, your options are different -- see our guides on debt consolidation and what to do when you can't afford minimum payments.

6

Document Everything

Keep copies of all letters, notes on all phone calls (date, time, collector name, what was said), certified mail receipts, and any evidence of when you last made a payment on the debt. This documentation is your shield if the collector files a lawsuit or violates the FDCPA. Store everything in a dedicated folder -- you may need it.

What to Say to Collectors About Time-Barred Debt

If you have determined that a debt is time-barred and the collector continues to contact you, you can send them a letter with language like this:

"I have reviewed my records and determined that the alleged debt referenced in your communication dated [date] is beyond the applicable statute of limitations under [your state] law. The last activity on this account was on [date], which is more than [X] years ago -- the statute of limitations period for this type of debt in my state.

I am aware that this debt is time-barred and that you cannot obtain a judgment against me for this debt. I demand that you cease all collection activity regarding this account. If you file a lawsuit on this time-barred debt, I will raise the statute of limitations as an affirmative defense and may pursue claims under the FDCPA and applicable state law for attempting to collect a time-barred debt."

Send this letter by certified mail with return receipt requested. Keep a copy. If the collector continues to contact you after receiving this letter, they may be violating both the FDCPA and the CFPB's Regulation F, and you may have grounds for a complaint or legal action.

Should You Ever Pay a Time-Barred Debt?

This is a personal decision, but here are the facts to consider:

Whatever you decide, do it from a position of knowledge, not fear. Understanding the statute of limitations gives you the power to make the right choice for your situation, not the choice the collector wants you to make.

Special Cases: Debts With Different Rules

Not all debts follow the standard statute of limitations rules. Some debts have special legal treatment that can extend or eliminate the SOL entirely.

Federal Student Loans

Federal student loans do not have a statute of limitations in the traditional sense. The federal government can pursue collection on federal student loans indefinitely through administrative tools like wage garnishment (up to 15% of disposable pay without a court order), tax refund offsets, and Social Security benefit offsets. The government does not need to sue you to collect a federal student loan -- it has administrative collection authority granted by Congress. If you are struggling with student loan debt, see our guide on student loan forgiveness options.

Private student loans, however, are subject to the same state statute of limitations rules as other consumer debts. They are typically classified as written contracts or promissory notes, depending on the state.

Tax Debt

Federal tax debt has a 10-year statute of limitations for collection, measured from the date the tax was assessed. However, this period can be extended or suspended in various circumstances, including if you file for bankruptcy, request an installment agreement, or live outside the United States for an extended period. State tax debts follow state-specific rules, which may differ from the consumer debt SOL periods listed in the table above.

Child Support and Alimony

Child support and alimony obligations generally do not have a statute of limitations in most states. These obligations continue until they are paid in full, and in many states, unpaid child support accumulates interest. Some states have enacted specific SOL periods for past-due child support (called "arrears"), but these are typically much longer than consumer debt SOLs -- often 10-20 years or more.

Judgments

If a creditor has already obtained a court judgment against you, the statute of limitations on the original debt no longer applies. Instead, the judgment itself has its own lifespan, which varies by state but is typically 10-20 years and can often be renewed. A judgment gives the creditor powerful collection tools, including wage garnishment, bank levies, and property liens. If you have a judgment against you, consult with a consumer rights attorney about your options.

Frequently Asked Questions

What is the statute of limitations on debt?

The statute of limitations on debt is a state law that sets the maximum time period during which a creditor or debt collector can file a lawsuit to collect a debt. Once this period expires, the debt becomes time-barred, meaning the collector cannot successfully sue you for it. However, the exact time period varies by state and debt type, ranging from 3 years in states like Mississippi and North Carolina to 15 years in Kentucky for written contracts. The clock typically starts from the date of your last payment or last account activity.

Can a debt collector still contact me after the statute of limitations expires?

Yes. Even after the statute of limitations expires, debt collectors can still contact you and request payment. What they cannot do is successfully sue you in court to collect the debt. If they file a lawsuit on a time-barred debt, you can raise the statute of limitations as an affirmative defense and the case should be dismissed. However, the collector is not required to stop calling or sending letters unless the debt is also beyond the 7-year credit reporting period under the FCRA or your state specifically prohibits collection activity on time-barred debts.

What actions can restart the statute of limitations clock?

The statute of limitations clock can be restarted by several actions depending on your state law: making a partial payment on the debt (even as little as $1), making a written or verbal acknowledgment that you owe the debt, signing a new payment agreement or promise to pay, or making a new charge on a credit card account. Be very careful when speaking with collectors about old debts, as anything that can be interpreted as acknowledging the debt may restart the clock and give the collector a fresh window to sue you. The safest approach is to communicate only in writing and avoid any language that admits you owe the debt.

What is the difference between the statute of limitations and the 7-year credit reporting period?

These are two completely separate timelines governed by different laws. The statute of limitations is a state law that determines how long a creditor can sue you for a debt. The 7-year credit reporting period under the Fair Credit Reporting Act is a federal law that determines how long a negative item can remain on your credit report. A debt can be past the statute of limitations but still appear on your credit report, or it can fall off your credit report while still being within the statute of limitations. The two clocks run independently of each other.

Should I pay a debt that is past the statute of limitations?

Paying a time-barred debt will not restart the statute of limitations in most states because the clock has already expired. However, in some states, making a partial payment on a time-barred debt can revive the entire debt and create a new SOL period. Before making any payment on an old debt, understand the specific laws in your state. Some consumers choose to settle time-barred debts for a fraction of the balance to improve their credit or peace of mind. If you decide to settle, always get the agreement in writing before sending any money.

Can a collector sue me for a time-barred debt?

A collector can file a lawsuit for a time-barred debt, but if you appear in court and raise the statute of limitations as an affirmative defense, the case should be dismissed. The critical issue is that you must appear in court and actively raise this defense -- courts do not dismiss cases on their own. If you ignore a lawsuit (even for a time-barred debt), the collector can get a default judgment against you, which gives them full legal collection power. Always respond to any court filing, even if you believe the debt is time-barred.

How do I know if my debt is time-barred?

To determine if a debt is time-barred, you need to know three things: the type of debt (written contract, oral agreement, promissory note, or open-ended account like a credit card), the date of your last payment or last activity on the account, and the statute of limitations period for that debt type in your state. Use the 50-state table in this guide to find your state's specific time periods. If the time since your last activity exceeds the SOL period, the debt is likely time-barred. If you are not sure, send a debt validation letter to the collector and demand the date of last activity -- they are required to provide this information.

Does the statute of limitations apply to all types of debt?

The statute of limitations applies to most consumer debts, including credit cards, medical bills, personal loans, auto loan deficiencies, and private student loans. However, some debts have different or no statute of limitations. Federal student loans can be collected indefinitely through administrative actions. Tax debts have a 10-year federal SOL. Child support and alimony obligations often have no SOL or very long periods. Court judgments have their own SOL periods that are typically longer than consumer debt SOLs. Government debts may also have different rules than private debts.
