A "foreign LLC" is just an LLC doing business in a state other than the one that formed it. If yours is doing business in a state where you never registered it, two things can happen. Many states charge a fine for each year you were not registered, from $150 a year to $10,000 a year depending on the state. States also restrict access to their courts until you register. The scope varies: Ohio, for example, restricts debt-collection proceedings rather than every type of lawsuit.
A restriction on bringing a lawsuit can matter when an LLC needs to collect an unpaid invoice. Check registration requirements before a dispute creates an urgent deadline.
The short answer
Nonregistration alone generally does not void your contracts or make you personally liable for company debts; the exceptions are explained below. You may owe back fees and penalties, depending on the state. Registration is also needed to remove restrictions on bringing certain lawsuits. Check your state's rule and cure process before calculating what you owe.
In four states the fine itself can be charged to members or managers personally, even though the company’s debts stay the company’s. The four-state personal fine ↓
- You need to sue someone in that state Check whether your claim falls within the state's registration bar and begin any required registration promptly. Registering does not pause any legal deadline on the claim itself, so if one is close, talk to a lawyer now; some states let a case that is already filed wait for the registration rather than be thrown out.
- You have been operating there for a while If registration is required, register promptly. Past fees and penalties may still apply, but assessment and collection vary by state. Some fines require a court proceeding; they are not all automatically billed when you file. Waiting can increase exposure where penalties recur. Find your state's penalty page.
- You are not sure you count as "doing business" there Many activities do not cross the line. The free 90-second check walks through yours, and the enforcement guide covers how states actually find out.
If you are about to register
Registering means filing a foreign LLC registration with that state and naming a registered agent there, someone with a street address in the state who can accept legal papers for you. If you do not have one, this is the simplest part to fix, and the cheapest reliable option is a nationwide service. The major three:

What the fine looks like in seven states
The limits work differently. Alaska and Vermont can charge up to $10,000 per year. Michigan caps the LLC's penalty at $10,000 but can impose separate personal fines. A yearly limit is not a cap on the whole bill. Check the timing and conditions in your state's guide.
Penalty amounts by state (2026)
- Alaska
- Up to $10,000 for each calendar year, including partial years
- California
- $2,000/yr FTB penalty + $800/yr franchise tax + $250/SOI
- Arkansas
- Up to $5,000 per 12-month period
- Colorado
- Up to $5,000 (statutory max)
- Texas
- $750/yr late fee after 90 days + back franchise tax
- Florida
- $500 to $1,000 per year
- Alabama
- $150/yr (no cap) + Business Privilege Tax exposure
California in particular is the highest-stakes state in the country to be unregistered in. Your own state's fine, the law behind it, and how to fix it are on its page below.

What does not happen, in any state
Three protections apply everywhere. They matter because they are the things people are most afraid of, and they are not actually a risk.
Your contracts generally remain valid. Failing to register does not generally void a contract. Montana has an exception: a contract with the state, a state agency or a local government can be voided by that government body (Mont. Code 35-8-1002(6)). Contract validity and access to court are separate questions. You may still need to register before suing to enforce a contract.
Your liability shield stays intact, with a four-state caveat. Members and managers of an unregistered foreign LLC do not become personally liable for the LLC's debts just because the LLC failed to register. The personal liability protection of an LLC is governed by the state where it was formed, not the state where it is operating, and most foreign-entity statutes include explicit language preserving the shield during periods of nonregistration. Four states add something different, and it is worth knowing because it is easy to confuse with losing the shield: they assess the PENALTY on the individual as well as the company. Virginia charges $500 to $5,000 to each member, manager or employee who knowingly does business unregistered (Va. Code 13.1-1057(D)). Michigan caps individual exposure at $10,000. North Dakota goes up to $1,000 for each governor, or where the company has no governors each member or agent, who authorized, directed or took part in the business there. Maryland goes up to $1,000 per member or agent, where it is a criminal misdemeanor. Your company's debts are still not yours in those four. The fine is.
You can defend lawsuits. Even when the closed-door rule blocks you from filing your own suit, you are still allowed to defend any lawsuit brought against you. If you get sued in a state where you are not registered, you can hire a lawyer and respond. The closed-door rule is a one-way restriction. Vermont goes further: until you register you may defend, but you may not raise a counterclaim, crossclaim or affirmative defense (11 V.S.A. 4119).
How to fix it
Whatever state you are unregistered in, the fix looks roughly the same:
1. Check whether a home-state certificate is required. A certificate of good standing shows that your LLC is current on its home-state filings. Some destinations accept a statement or an online status check instead, so check the registration form before ordering one. If required, the certificate costs $0 to $50 depending on your home state; the destination sets how recent it must be.
2. File the foreign LLC registration in the state where you have been operating. The form name varies (Application for Certificate of Authority, Statement of Foreign Qualification, Foreign LLC Registration). The fee runs $50 to $750 depending on the state. Online filing is available in most states.
3. Resolve applicable back fees and penalties. Follow your state's cure process and any assessment or court order. A statutory maximum is not automatically your bill. For example, Nevada's fine requires willful failure and recovery in court. The per-state pages explain the amounts and conditions.
4. Catch up on tax filings. Separately from the SOS penalty, the state's Department of Revenue or Franchise Tax Board will want back-year filings for franchise tax, income tax (if applicable), and sales tax (if you had nexus).
5. Appoint a registered agent. Most states require a registered agent with an in-state address. New York makes an additional agent optional because its Secretary of State receives legal papers. If you do not have one, this is the simplest piece to fix; commercial services cover all 50 states under one account.
How states find out
The penalty statute describes legal exposure, not how frequently a state enforces it. Registration gaps can surface through agency inquiries, licensing or litigation; the sources here do not establish nationwide detection rates.
Tax and payroll filings, license applications, litigation and property transactions can prompt questions about registration. Those events do not all establish that foreign qualification is required: tax nexus and entity registration use different tests.
The companion enforcement guide explains situations to review and how to distinguish registration requirements from tax obligations. It does not assign a percentage chance of getting caught.
What to watch out for
- Penalties stack annually in most states. A 5-year unregistered exposure in Alaska can be $50,000 in civil penalty alone, before back fees and taxes.
- A sales-tax registration does not automatically establish a foreign-qualification obligation. Check both sets of rules separately.
- Registration cures the closed door for past disputes as well as new ones. A few states add conditions: Puerto Rico, for example, requires every back fee and penalty to be paid before you can file.
- Tax penalties (franchise tax, sales tax, employer withholding) are separate from the foreign LLC penalty itself. Each state agency has its own penalty structure. The numbers in this guide are the foreign-LLC-specific penalty only.
Common questions
What is the worst that can happen if I do not register my foreign LLC? Consequences can include restrictions on bringing a lawsuit, accumulated fees, civil penalties and an injunction against further business. The court restriction varies: Ohio's rule covers debt collection. Review your state's page before estimating exposure, and do not wait out a deadline on an underlying claim.
Do penalties keep accruing forever, or is there a statute of limitations? Check the particular charge and state. Recurring penalties, statutory caps, collection deadlines and tax assessment periods are different rules. Do not assume either unlimited liability or a single nationwide cutoff.
Will I be personally liable for my LLC's debts because I did not register? No. Failing to register does not expose your personal assets to the company's debts in any state. One thing that is easy to mistake for it: in Virginia, Michigan, North Dakota and Maryland the statutory penalty can be assessed on a member or manager personally, not only on the company. That is a fine you owe the state, not the company's creditors reaching through to you.
Are my contracts void if I signed them while unregistered? Generally, no. Montana allows a government body to void its contract with an unregistered LLC. Elsewhere, keeping a valid contract does not necessarily mean you can sue to enforce it before registering. Check your state's court-access rule above.
Can I just register now and have the penalty go away? Registering does not automatically erase liability from past unregistered activity. Applicable back fees, penalties and payment conditions depend on the state; some fines require enforcement proceedings rather than automatic assessment at registration. Registration generally cures the court-access restriction, subject to the state's additional cure requirements. It does not extend the deadline for your underlying claim.
Does the state actively look for unregistered foreign LLCs? Enforcement authority and agency practices vary. Nevada law, for example, authorizes the Secretary of State to investigate possible violations. That authority does not establish how often investigations occur. See the enforcement guide for the distinction.
Bottom line
If you are operating in a state where you are not registered, the practical decision is whether to wait until something forces the issue or to register proactively. The math usually favors registering. For your state's exact penalty and cure process, use the directory above. For whether enforcement is likely to actually find you in the meantime, see the enforcement-risk guide.

How the states sort, for the reader who wants the detail
Everything above is enough to decide and to act. The three sections below are the classification behind it: how the 50 states, the District of Columbia and Puerto Rico split into three kinds of penalty, what the courthouse rule covers in each, and one court case that shows it in practice.
The three penalty tiersWhich states fine you, which only close the courthouse door, and which do both
Foreign LLC penalty rules sort cleanly into three categories. The category your state falls into is the most important factor in how exposed you are.
Tier 1: Direct civil penalty (30 jurisdictions) High exposure
These jurisdictions charge a specific dollar penalty for operating without a foreign LLC registration. The penalty is per year (or per partial year) of unregistered operation, and most have no overall cap, so multi-year exposure stacks. The state attorney general or Secretary of State brings the recovery action. The amounts vary by two orders of magnitude, so being in this tier tells you the shape of the exposure rather than its size: Alabama at $150 a year, and Delaware and New Jersey at $200, sit at the bottom of it.
Examples of the dollar amounts. Alaska charges up to $10,000 per calendar year. Texas charges $750 per year of delinquency in late fees, but only once you have been doing business there for more than 90 days; the back franchise tax has no such threshold. Arkansas and Colorado cap at $5,000 (Arkansas per 12-month period with no overall cap, Colorado total). Florida charges $500 to $1,000 per year. Alabama charges $150 per year of delinquency with no statutory cap, layered on top of Business Privilege Tax exposure.
The 30 jurisdictions in this tier: Alabama, Alaska, Arkansas, Colorado, Connecticut, Delaware, Florida, Georgia, Illinois, Indiana, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Missouri, Montana, Nevada, New Jersey, New Mexico, North Carolina, North Dakota, Puerto Rico, Tennessee, Texas, Vermont, Virginia, Wisconsin, Wyoming.
Tier 2: Indirect penalty only (20 jurisdictions) Medium exposure
These jurisdictions do not charge a flat civil penalty. The penalty is the closed-door rule (limits on court claims until you register). Some of these states also charge back fees for the years you operated unregistered, and any taxes you already owed still apply, with their own interest and penalties (sales tax, employer withholding, franchise tax). The Attorney General can also seek an injunction to stop you from doing further business in the state.
For most operating LLCs the indirect tier is still expensive once it triggers. New York is in this tier: it charges no civil penalty and nothing for the unregistered years, but the LLC cannot bring a lawsuit in a New York court until it registers, and registering brings New York's publication requirement with it. Delaware is not in this tier, despite often being described that way: it charges $200 for each year of unregistered operation under 6 Del. C. section 18-907, and the franchise tax back-bill sits on top of that.
The 20 jurisdictions in this tier: Arizona, District of Columbia, Hawaii, Idaho, Iowa, Kansas, Minnesota, Mississippi, Nebraska, New Hampshire, New York, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, South Dakota, Utah, Washington, West Virginia.
Tier 3: Mixed (2 jurisdictions) High exposure
California and Ohio combine both. California has no flat civil penalty under the LLC Act itself, but the Franchise Tax Board imposes a $2,000-per-year penalty under R&TC section 19135 if you fail to file within 60 days of an FTB demand notice. On top of that, you owe the $800 annual franchise tax for every year you were doing business in California, plus a $250 penalty for each missed Statement of Information. Ohio is a different shape. Its statute names no dollar amount at all: the company owes an amount equal to the registration fee it should have paid, once rather than once per year, and no registration can be filed until that is paid. Beyond that the Attorney General can sue and a court can set a civil penalty of its own and add an injunction. Ohio's closed door is also narrower than most, covering only suits brought to collect the company's debts.
If your LLC is operating in California or Ohio without registration, the math gets bad fast.
The penalty for not registering depends on the state. 30 jurisdictions charge a direct civil penalty; the table above explains the different limits. 20 jurisdictions charge no flat fine but restrict court access until you register. 2 jurisdictions (California and Ohio) stack both. Contracts generally remain valid, subject to Montana's government-contract exception. In 48 the closed door covers every civil action, and in Colorado, Maine and Ohio it covers debt collection only. Texas closes it only for claims that arise from the business you did there. In four states the penalty itself can land on you personally.
The closed-door rule, state by stateWhich court claims are restricted, and how registration helps
Every one of the 50 states, the District of Columbia and Puerto Rico has some version of this rule. If your foreign LLC conducts activities that require registration but has not registered, the state's registration bar can prevent it from maintaining a covered court action until it registers. Merely bringing a lawsuit does not itself establish a registration requirement. In 48 of them the bar is not limited to debt collection and can cover claims such as: collections, breach-of-contract claims, IP enforcement, debt recovery, lease disputes, eviction proceedings arising from rental operations. Colorado, Maine and Ohio are narrower, closing the door only on proceedings brought to collect the company's debts, so a claim that is not a debt collection can still be filed there. Texas closes it only for claims that arise from the business you did there. Your state's page above says which rule applies.
In every state, the rule is curable. You can register, pay the back fees and any penalty, and then file your case. But the time it takes to cure (typically 1 to 6 weeks depending on processing) plus the back-fee bill is what most LLCs run into when they want to sue an unpaid customer or a counterparty.
This is the most common "caught" moment for an unregistered foreign LLC: a contract dispute or unpaid invoice surfaces, you go to file suit, your lawyer asks whether you are registered, and the answer is no. Now you are not just dealing with the dispute; you are also dealing with the back-registration math before you can even start the dispute.
