Built by a tax preparer, for tax preparers — J&L Charles LLC · Florida · info@jlcharles.services
The problem
Every return means copying the same information from W-2s, 1099s, and client documents into TaxSlayer Pro field by field. That's hours of your life every season — on work that adds zero value to your clients.
Average preparer spends 15–20 minutes per return just on data entry. At 200 returns that's 60+ hours.
Manual entry means transposition errors. One wrong digit can trigger an IRS notice or delay a refund.
Repetitive data entry at peak season is exhausting. It's the part of the job everyone dreads most.

Real feedback from tax professionals who use PrepWiz every season.
"I used to spend 20 minutes per return just on data entry. PrepWiz cut that to under 5. During peak season that's hours back in my day."
"The accuracy is what sold me. I used to make transposition errors when I was tired. PrepWiz fills the fields correctly every time — I just verify."
"Setup took less than 10 minutes. By the end of day one I had already saved more time than the cost of the license. Worth every penny."
