The stakes

The traps nobody warns you about.

You're great at your trade. Nobody hands you a calendar of the filings that keep your business legal. Miss one and the state doesn't send a warning — it sends a bill.

The price gap
$399/mo vs. $50/yr

The only tools that track this today start at $399/month and are built for funded companies. PenaltyProof is built for you.

Administrative dissolution
Miss 2 annual reports → dissolved.

Skip two years of a state annual report and your LLC can be shut down — no warning letter, and reinstatement costs money and time.

Sales tax penalty
Up to 25% — even on $0 owed.

File a sales-tax return late and penalties stack up to 25% plus interest — in many states you must file even when you owed nothing.

Economic nexus
Sell into a new state? You may owe it.

Economic-nexus thresholds vary by state and can depend on revenue, transaction type, and other factors. Most owners never find out a state started counting until it's late.
