Yes. Corporations must comply with statutory rules that unincorporated businesses, such as limited liability companies (LLCs), partnerships, and sole proprietorships, do not. For instance, corporations must observe corporate formalities such as holding and taking minutes of annual shareholder and director meetings and documenting important decisions. Also, corporations must file and pay taxes on a separate corporate tax return and must set up a double-entry bookkeeping system to record business transactions, complete with daily journals and a general ledger.
