The RetroTax Developer Hub

Welcome to the RetroTax developer hub. This API allows RetroTax partners to seamlessly integrate WOTC screening, in addition to geographic and state-level tax credits, into their existing software platforms so that RetroTax can handle the back-end logic to screen and process candidates. You'll find comprehensive guides and documentation to help you start working with RetroTax as quickly as possible, as well as support if you get stuck. Let's jump right in!

WOTC Overview

The Work Opportunity Tax Credit (WOTC) program is an incentive program that provides businesses with a federal income tax credit to hire individuals from targeted groups that have a particularly high unemployment rate or other special employment needs. The WOTC credit is calculated on “qualified first-year wages” and has a maximum credit of $2,400, $4,800, $5,600 or $9,600 per eligible employee, depending upon the employee’s eligible Target Group. For more detailed information, read IRS Publication 954
