Sarah sells sandals at her family owned beach store in Panama City, Florida. Sarah's dad, the owner of the store, had a limited financial background and would estimate his multifactor productivity ratios when reporting them to the IRS. The IRS noticed the suspicious activity and has asked the sandal store to recalculate their multifactor productivity ratio and resubmit financial information.
