Sales tax exposure doesn’t fix itself. We Do.
We challenge state tax agencies on behalf of businesses. The New York Department of Tax and Finance, California CDTFA, Illinois DOR, Texas Comptroller, and dozens more. This is all we do.

Sales tax is complex by design. Most businesses are more exposed than they realize.
Most business owners want to be compliant, but sales tax is confusing by design and changes constantly. The rules differ by state, by product, by transaction type. The exposure builds quietly, until the state finds it first.
Unlike traditional compliance software that hands you a form, or generalist CPAs who dabble in tax, every expert on our team works exclusively on sales tax. Nothing else.
You’re not alone. Here’s what changes when you work with us.
Terrified after receiving an audit notice, assessment, or collection letter from the state
Sleepless nights worrying about the size of a tax bill, unexpected penalties, or even criminal accusations
Overwhelmed by confusing notices, aggressive auditors, or threats of legal action
Anxious about hidden exposure that could cost you your business, reputation, or financial security
Unsure where to turn or who will defend you when the state comes knocking
Paralyzed by fear that a small mistake could lead to a big disaster
Constantly distracted from running or growing your business because of sales tax worries
You’re not alone. You don’t have to face the government by yourself.
What Clients Say
Why Jerry Built Sales Tax Helper
I started Sales Tax Helper because I’ve seen firsthand how sales tax confusion, fear, and exposure can disrupt - even destroy - businesses and lives. I know what it feels like to lose sleep over a letter from the state.
My mission is simple: no business owner should have to face sales tax stress alone, or risk everything they’ve built because of a system that’s confusing by design. Whether you want to do it yourself or have us handle it all - we meet you where you are.
