Supporting America's Young Entrepreneurs Act of 2019 This bill makes eligible for deferment and cancelation of student loan debt a recent graduate of a four-year institution of higher education (IHE) who works at certain small business start-ups in distressed areas. Specifically, it makes a student loan borrower who is an employee and founder of a start-up eligible for deferment and cancellation of student loans. In addition, the bill makes a full-time employee of a start-up eligible for cancelation of student loan debt. It also excludes from an individual's gross income, for income tax purposes, the amount of such canceled student loan debt. Finally, it establishes a young entrepreneurs business center within the Small Business Administration to certify small business start-ups, identify distressed areas, and approve loan cancellations. To be certified by the center, a start-up must (1) have a founder who is a recent graduate of a four-year IHE, and (2) employ a certain number of recent graduates.
