Samplwitt

Did an auditor sample one month and bill you for three years?

That is how a sales tax audit works. The auditor reviews a short period, calculates an error rate, and projects it across the whole audit span. A slip in one busy month can become a six-figure assessment - and the deadline to protest the result is short.

Samplwitt is a contemporaneous audit-defense organizer for the small-business owner who has been notified of a state sales tax audit. Restaurant, retail, contractor, e-commerce, auto dealer - if a state department of revenue has put your books under review, Samplwitt helps you organize evidence, build a sampling objection, and keep every deadline in front of you.

LOG THE AUDIT
Record each audit case - tax authority, audit period, auditor, notice date - and see your protest / redetermination deadline on screen with a countdown.

ORGANIZE CERTIFICATES
Keep your exemption certificates, resale certificates, and sales records organized under the audit case they belong to.

CHALLENGE THE SAMPLE
The sample is where audits are won or lost. The Sampling Objection Workbook helps you assemble a written objection - the sample period the auditor used, your month-by-month busy and slow seasons, why the sample is not representative, a stratified-sample proposal, and an exhibit list.

KNOW THE PROCESS
Browse a built-in reference to each state's sales tax and appeal procedure, with the protest window and where to file.
