Usury Laws in Massachusetts (2026): The Interest Rate Rules That Protect You
Most people have no idea how many borrowing protections they actually have. Seriously. But in Massachusetts, usury laws set clear limits on how much interest a lender can charge you. Break these rules, and a lender could face prison time.
Let’s break down exactly what these laws mean for you.
What Is Usury?

Usury is the practice of charging interest rates that are too high. Think of it like a speed limit, but for loans. Go over the limit, and there are consequences.
Massachusetts usury laws exist to protect borrowers. They stop lenders from trapping you in debt with sky-high rates you can never escape. Honestly, these protections are more important than most people realize.
Wondering if this applies to you? If you’ve ever taken out a personal loan, a small loan, or borrowed money from a private lender, yes, it probably does.
The Basic Interest Rate Rules
The 6% Default Rate
Here’s where it gets interesting. Massachusetts sets its default interest rate at 6% per year. This is the rate that applies when you and a lender haven’t signed a written contract agreeing to something different.
So simple! If there’s no written agreement on the rate, the law caps it at 6%. That’s your baseline protection.
The 20% Criminal Threshold
Now, here’s where things get serious. If a lender charges you more than 20% interest per year, they are committing a crime in Massachusetts. This is called criminal usury. It doesn’t matter what you signed or what deal you thought you made.
The law is clear. Go above 20%, and you’re breaking the law.
Criminal Usury: What the Law Actually Says

Massachusetts General Law Chapter 271, Section 49 is the big one. It says that anyone who knowingly charges more than 20% interest per year on a loan can face serious criminal penalties.
Okay, pause. Read this carefully. This isn’t just a slap on the wrist.
A lender convicted of criminal usury in Massachusetts can face up to 10 years in state prison. They can also be fined up to $10,000. Or both. That’s not a small consequence.
Pretty straightforward, right? Charge too much interest, go to prison.
What Happens to the Loan Itself?
Here’s something most borrowers don’t know. If a lender charges you an illegal interest rate, you can actually ask a court to void the loan entirely.
You can petition the Supreme Judicial Court or Superior Court to declare the loan void. That means you could potentially be freed from the debt entirely. That’s a powerful protection.
A friend asked me about this last week. She had no idea this option even existed. Turns out, most people get it wrong. They think they have no recourse. They actually do.
Small Loans: Special Rules Apply

Not sure what counts as a “small loan”? Let me break it down.
In Massachusetts, loans of $6,000 or less are regulated under a separate law. Lenders making these smaller loans need a license from the Massachusetts Division of Banks. If they charge more than 12% annually on these loans, they need that license.
Hold on, this part is important. Even with a license, the maximum interest rate on small loans is capped at 23% per year under state regulations. So there’s a hard ceiling even for licensed small lenders.
If a small loan is made by an unlicensed lender, or if the rates go above the legal limit, that loan is void. Unenforceable. The lender cannot collect on it. This is a really strong protection for borrowers.
The Attorney General Loophole (Yes, Really)
Wait, it gets more complicated. Massachusetts has a unique mechanism that no other state really copies.
A lender can actually charge more than 20% interest if they file a notice with the Massachusetts Attorney General first. They have to notify the AG of their intent to charge a rate above the criminal threshold. They also have to keep certain records.
You’re not alone if this surprises you. Most people have no idea this exists.
If a lender files that notice correctly before giving you the money, they can legally charge more than 20%. But here’s the catch: they still have to comply with other consumer protection laws. And courts can still strike down rates that are considered unreasonable under contract law principles.
This doesn’t mean lenders can charge whatever they want. It just means the 20% criminal cap has a specific workaround with extra steps. Lenders who skip those steps still face criminal charges.
Written Contracts Change Everything
Here’s something really important to understand. The 6% default rate is just that: a default.
If you and a lender both agree in writing to a higher rate, that agreement can be enforceable. Massachusetts allows parties to contract for higher rates in a written agreement. This is why most personal loans and mortgages carry rates above 6%.
Think of it like a traffic ticket, but more serious. You can technically agree to go faster, but there are still limits.
The key is that the written agreement has to be fair and legal. If the rate crosses into criminal territory and the lender hasn’t properly notified the Attorney General, you could have a strong case to challenge the loan.
Credit Cards: A Different Story
Confused about how usury laws apply to your credit card? It’s actually a different situation entirely.
Most credit cards are issued by national banks. National banks follow the rules of the state where the bank is chartered, not where you live. Massachusetts credit card law generally limits rates to 18% for state-issued cards.
But here’s the thing: your credit card from a bank chartered in Delaware or South Dakota may be subject to that state’s rules. Some states have very high limits or no limits at all. This is why your credit card APR can be 25% or even higher even though you live in Massachusetts.
Personally, I think this federal loophole is the part most people miss. It’s the one area where Massachusetts can’t fully protect you.
Mortgage Loans and Predatory Lending
Massachusetts takes predatory mortgage lending very seriously. Chapter 183C of Massachusetts General Laws covers high-cost home loans.
In September 2025, the Massachusetts Division of Banks finalized important updates to small loan regulations, mortgage licensing rules, and disclosure requirements. These changes mean lenders now have stronger obligations to be transparent with you about rates, fees, and loan terms.
The new rules also tightened up how lenders can adjust interest rates on adjustable-rate mortgages. Now, lenders must give you notice at least 60 days, but no more than 120 days, before your first adjusted payment is due.
Stay with me here. These protections are real, and they matter when you’re taking on a mortgage.
Penalties and Consequences at a Glance
Let’s talk about what actually happens when these laws are broken.
If a lender charges more than 20% without the Attorney General notice process: that’s criminal usury. Up to 10 years in prison and up to a $10,000 fine. The loan can be voided by a court.
If a small loan lender operates without a license: the loan is void and unenforceable. The lender cannot collect the debt.
If a lender violates Massachusetts consumer protection laws: the borrower may have additional civil remedies. They could potentially recover money they already paid in excess interest.
Less severe than federal crimes, but still no joke. Massachusetts takes this seriously.
Exceptions to Know About
Not every loan falls under Massachusetts usury rules. A few important exceptions exist.
National banks are largely exempt from state usury laws. This is a federal rule that applies nationwide. The Monetary Control Act of 1980 also gives certain lenders the ability to charge rates above what state law would normally allow.
Life insurance policy loans have their own interest rate rules. Open-end credit transactions like home equity lines of credit also have specific rules that can differ from standard loan limits.
Most people assume usury laws cover everything. They find out the hard way that some lenders fall outside state rules entirely. Don’t be one of them.
How to Protect Yourself
You’re not alone if this feels overwhelming. Here’s what you can actually do to protect yourself.
Always read your loan agreement before signing. Look at the Annual Percentage Rate, not just the monthly payment. The APR includes fees and tells you the true cost of borrowing.
Ask the lender directly: are you licensed by the Massachusetts Division of Banks? For small loans under $6,000, this matters a lot.
If you believe a lender is charging illegal interest rates, you can file a complaint with the Massachusetts Division of Banks. You can also contact the Massachusetts Attorney General’s consumer protection office.
And here’s my honest take: if a loan seems too good to be true or you feel pressured into signing, walk away. Predatory lenders count on people feeling desperate.
How to Report an Illegal Lender
If you think someone has violated Massachusetts usury laws, here’s what to do.
Contact the Massachusetts Division of Banks. Their enforcement team has already issued cease and desist orders to unlicensed lenders, including many operating online. They take illegal lending seriously.
You can also reach out to the Massachusetts Attorney General’s office. They work on consumer protection cases and can investigate lenders charging illegal rates.
If the loan is already in your hands, talk to a consumer protection attorney. They can help you figure out whether the loan is void and whether you can recover any overpaid interest.
Frequently Asked Questions
What is the maximum interest rate in Massachusetts? The default rate is 6% per year without a written agreement. With a written contract, rates above 6% are allowed. Criminal usury kicks in above 20%, unless the lender has properly notified the Attorney General.
Can I go to court to cancel a loan with an illegal interest rate? Yes. You can petition the Superior Court or Supreme Judicial Court to void a loan that carries an illegal interest rate. Courts have the power to cancel the loan entirely.
Are payday loans legal in Massachusetts? No. Payday lending is effectively banned in Massachusetts. The Division of Banks has issued hundreds of cease and desist orders against payday lenders operating in the state.
Does my credit card fall under Massachusetts usury law? Not always. If your credit card is from a national bank chartered in another state, that state’s interest rate rules may apply instead of Massachusetts rules.
What happens if I borrowed money from an unlicensed small lender? If the lender is unlicensed and the loan falls under the small loan statute, the loan may be void. You may not legally owe the money. Speak with a consumer protection attorney to find out your options.
Can a lender legally charge more than 20% in Massachusetts? Yes, but only if the lender files a proper notice with the Massachusetts Attorney General before issuing the loan. Even then, other consumer protection laws still apply.
