The stakes
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 only tools that track this today start at $399/month and are built for funded companies. PenaltyProof is built for you.
Skip two years of a state annual report and your LLC can be shut down — no warning letter, and reinstatement costs money and time.
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.
Cross about $100k of sales in a state you've never set foot in and you must register and file there. Most owners never find out until it's late.
How it works
Your state, your business type, how many people you employ. That's it.
Every deadline that actually applies to you — and nothing that doesn't.
Text and email, in your language, before each due date. One tap marks it done.
Coverage
Stay in good standing. Never get silently dissolved.
Your filing cadence, plus a heads-up when a new state starts to count.
The tax accounts you're required to open the moment you hire across a state line.
The state rules that change every January — updated for you.
The federal calendar every employer shares, tracked alongside your state's.
One tap produces the paper trail when an inspector asks for it.
Who it's for
A restaurant, salon, shop, or contractor. You get the handful of deadlines that apply where you operate — nothing to wade through.
Selling online or hiring remote? Add each new state and PenaltyProof folds its deadlines and nexus rules into one dashboard.
