The Work Opportunity Tax Credit (WOTC) provides a federal tax credit to employers, not employees. Job applicants who fit within one of nine WOTC target groups may benefit from the program though, as it provides an incentive for employers to hire them.
If you are looking for a job, you should consider having your WOTC eligibility pre-screened by the Employment Development Department
. If you are WOTC-eligible, you can let potential employers know.
