Business amendments are common and necessary when formation-level details change (name, purpose, authorized shares, management structure, etc.). The process always requires internal authorization under your entity documents, filing the correct state form with the required fee, and then updating federal and administrative records (IRS, licenses, banks, multi-state registrations). State requirements vary in form names, filing fees, signature rules, and whether some changes use dedicated change forms rather than an amendment; example specifics were captured for Texas (procedural rules, registered agent consent, 90-day delayed effectiveness) and New York (Certificate of Amendment, $60 fee). FinCEN removed BOI reporting requirements for domestic U.S. entities as of March 26, 2025, but foreign entities registered in the U.S. may still have BOI obligations and deadlines.
