ALERT: States Using AI to Audit Self-Prepared Schedule C Returns Within Days of Filing

Several states are now running returns through machine-learning systems the moment they are filed. Returns the algorithm scores as high-risk get an audit letter generated automatically and mailed within days. The refund has not arrived before the audit notice does.

The taxpayers we have seen receive these letters had one thing in common. They prepared and filed the return themselves, usually through consumer tax software, and they reported Schedule C income. If that describes your return, read the rest of this.

Why Self-Prepared Schedule C Returns Are Getting Hit First

Self-prepared Schedule C returns are the easiest target for an algorithm. The numbers are entered directly by the taxpayer, the deductions are not vetted by anyone, and common mistakes show up in predictable patterns. The system flags ratios that look off (deductions too large relative to gross receipts), home office claims that do not match the address, vehicle mileage that runs high for the industry, and business losses that conveniently zero out W-2 wages.

A return prepared by a tax professional gets reviewed before it goes out. A return filed at home through software does not. The algorithm knows the difference and the early audit volume reflects it.

What to Do If a Letter Arrives

Do not respond on instinct. The first response sets the record. Note the deadline (usually 30 days), pull your records for the line item the letter names, and call us before you send anything. If your records are thin, there are reconstruction methods and procedural arguments available. Most assessments can be reduced or eliminated with the right response.

If You Filed Your Own Return This Year

Schedule a review now. We can read your return the way the state's algorithm reads it and tell you where the risk is. If a letter shows up later, we can respond on your behalf. Either way, you find out before the state does.
