Most expensive founder mistakes are administrative, not strategic - a missed filing, a franchise-tax surprise, or a state that will not let you dissolve until back fees are paid. Know your recurring deadlines, keep them on a calendar, and close the company properly rather than abandoning it.
Know what recurs, and what changed
Rules in this space move constantly. BOI reporting shifted in 2025-2026, franchise tax and annual-report dates differ by state, and sales-tax nexus can arise from sales volume without any physical presence.
Walking away is not a clean exit. Administrative dissolution can leave state balances, missed filings and unresolved bank obligations - a proper shutdown includes dissolution, final filings and account closure.

Quick answers
Frequently asked questions
Do US LLCs still file a BOI report in 2026?
Current FinCEN rules exempt US-created domestic entities, while some foreign entities registered in the US may still be in scope. Old articles and paid letters can be wrong.
Can I just abandon an unused LLC?
No. Administrative dissolution can leave state balances and missed filings. A safe shutdown includes state dissolution, final filings and account closure.
