Compliance terms, plain English

A searchable reference for every term you'll encounter in entity compliance, no legal background required.

Annual Report
A periodic filing required by most states to keep a business entity's registration current. Confirms or updates the entity's name, address, registered agent, and key personnel. Not to be confused with a financial annual report.
SingleFile automates annual report tracking and filing →
Apostille
An authentication certificate issued by a state government that verifies the legitimacy of a public document for use in another country. Required for international business transactions, foreign company filings, and overseas legal proceedings.
Articles of Organization
The foundational legal document filed with a state to form a limited liability company (LLC). Contains the LLC name, registered agent, business address, members or managers, and purpose. Equivalent to Articles of Incorporation for corporations.
SingleFile handles entity formation in all 52 jurisdictions →
Certificate of Good Standing
An official document issued by a state agency confirming that an entity is properly registered and current on all state obligations. Often required for bank accounts, loans, mergers, foreign qualifications, and large business transactions.
SingleFile retrieves certificates from all 52 jurisdictions →
Dissolution
The formal process of ending a business entity's legal existence in its state of formation. Requires filing dissolution documents and settling outstanding obligations before the state removes the entity from its records.
SingleFile handles dissolution filings →
Domestic Entity
A business entity operating in the state where it was originally formed. The opposite of a foreign entity, an entity that's been registered to operate in a different state than its formation state.
Entity Formation
The legal process of creating a new business entity, LLC, corporation, LP, or other recognized structure, by filing formation documents with the appropriate state agency. The starting point of every business compliance lifecycle.
SingleFile files entity formations in any state →
Foreign Qualification
The process of registering a business entity to operate in a state other than its state of formation. Required when a company has employees, property, or significant operations in a new state.
SingleFile handles foreign qualification filings →
Franchise Tax
A tax imposed by some states on the privilege of operating a business entity in that state. Owed regardless of whether the entity is profitable. Common in Delaware, Texas, California, and easily confused with the entity's annual report obligation.
Incorporator
The person or entity that signs and files the Articles of Incorporation to create a new corporation. Often a lawyer, formation service, or one of the eventual founders. The incorporator has no ongoing role once the corporation is formed.
Operating Agreement
An internal document that governs how an LLC operates, ownership percentages, voting rights, distributions, and member responsibilities. Not filed with the state, but legally binding on the members. Strongly recommended even where it's not required.
Reinstatement
The process of restoring an entity to active status after it has been administratively dissolved or revoked by a state, typically for failure to file annual reports or pay fees. Each state has its own reinstatement process and fees.
SingleFile handles reinstatements in any state →
Service of Process
The formal delivery of legal documents, such as a lawsuit summons, subpoena, or court order, to a business entity. Must be received by the registered agent during normal business hours in the state where the entity is registered.
Statutory Agent
Another term for 'registered agent' used in some states (notably Arizona, Ohio, and West Virginia). The role is identical: receive legal documents and government correspondence on behalf of a business entity.
Withdrawal
The process of formally cancelling a foreign qualification, used when a business stops operating in a state where it was foreign-qualified. Avoids ongoing annual report obligations and fees. Distinct from dissolution, which ends the entity entirely.
SingleFile handles withdrawal filings →
