All formal business entities, including LLCs, are required to have a Registered Agent on file with the state at all times. The agent may be an individual or company with a physical address located in the state of incorporation. Agents must be available at all times during standard business hours (9 a.m. - 5 p.m. Monday – Friday). The role of a Registered Agent is to receive any and all of communications from the government to the business. The agent’s name and address must be disclosed as part of the company’s public record.
LLC members are taxed on their personal tax returns. The LLC itself is not taxed. S-Corp shareholders are taxed on their personal tax returns. The company itself is not taxed. C-Corps are taxed both at the corporate level and again on shareholders' individual returns. Non-Profits are taxed on a corporate level but may also enjoy a host of tax-exempt benefits. Sole Proprietorships are taxed only on their owner's tax return.

This is often the only form of limited partnership allowed for law firms (as opposed to general partnerships).
The "mit beschränkter Haftung (mbH)" suffix (German: [ˈɛmbeːˌhaː], "with limited liability") is sometimes added to the name of a firm that already ends in "-gesellschaft" ("company"), e.g., "Mustermann Dental-Handelsgesellschaft mit beschränkter Haftung" ("dental trading company with limited liability"), which would be abbreviated as "Mustermann Dental-Handelsgesellschaft mbH".
