Operating an LLC in another state without proper registration or compliance can lead to serious consequences. These may include fines and penalties imposed by the state. Additionally, you may lose the ability to bring a lawsuit in that state's courts.
In some cases, the state could even dissolve your LLC. Also, failing to comply with tax regulations can result in back taxes and penalties.
In short, not registering and complying correctly can lead to legal and financial headaches. To avoid these, work with MyCorporation. It's always better to be safe than sorry.
