What is foreign qualification?
An LLC is domestic in the state where it was formed and foreign everywhere else. Before a foreign LLC transacts business in a state, that state generally requires it to register, usually by filing an application for a certificate of authority or registration, paying a fee and appointing a registered agent in the state. After that it files the state's annual reports and pays its taxes, just as a domestic LLC would. The filing itself is covered in foreign LLC registration.
What counts as doing business in your home state?
Each state defines it in its own law, and the definitions vary. Activities that generally count include having an office or place of business in the state, employees working there, and owners running the business day to day from there. Activities that generally do not count on their own include holding bank accounts, isolated transactions, and selling to customers in the state by mail or online without a presence. If you live in a state and run your business from your home there, assume it counts.
What does it cost in practice?
Take an owner in California who forms in Wyoming to save money:
| Item | Wyoming LLC run from California | California LLC |
|---|---|---|
| Formation | $100 in Wyoming, plus California's registration fee | $70 |
| Yearly state charges | At least $60 in Wyoming, plus California's $800 minimum tax and statements | California's $800 minimum tax and statements |
| Registered agents | Two | One |
| State income tax | California's, on business run from California | California's |
California's minimum tax applies to LLCs doing business in California, whether formed there or not, so the Wyoming route adds cost rather than saving it. See how to form an LLC in California. Figures for other states are in how much an LLC costs.
What happens if you do not register?
Consequences vary by state, but commonly include:
- penalties and back fees and taxes for the period you should have been registered,
- being unable to bring a lawsuit in that state's courts until you register,
- problems with banks, licenses and contracts that ask for good standing in the state.
Contracts the LLC made generally remain valid, but you pay to catch up and cannot enforce them in court until you do.
When does another state make sense?
- You have no home state, for example because you live outside the US. See the best state for a non-resident LLC.
- Investors or lenders require a particular state's law, most often Delaware for corporations.
- The LLC only holds investments and does no business in your home state.
For the full decision, including the popular states compared, see which state to form your LLC in.
Moving yourself, rather than the LLC, is covered in states with no income tax.
What if you already formed in the wrong state?
Two options: register the existing LLC in your home state as a foreign LLC, or move it. Many states allow an LLC to convert or domesticate into their state, which avoids forming a new company and keeps its history. Otherwise you form a new LLC at home, transfer the business and dissolve the old one.
The ways to move, including domestication, are compared in how to move your LLC to another state.
Formed out of state and not registered at home?
We check whether your home state requires registration, file the foreign qualification, and bring the company into good standing in both states.
Questions people ask
Should I form my LLC in my home state?
Usually yes. If you run the business from your home state, it will generally require registration there anyway, so forming elsewhere adds a second set of fees.
What is a foreign LLC?
An LLC doing business in a state other than the one where it was formed. It registers in the second state through foreign qualification.
What happens if I don't register my LLC in my home state?
Commonly penalties, back fees and taxes, and being unable to sue in that state's courts until you register.
Can I move my LLC to my home state?
Often yes. Many states allow conversion or domestication, which moves the LLC without forming a new one.
