Investing in American Workers Act

This bill creates a new tax credit for employers who provide training to non-highly compensated employees that leads to recognized postsecondary credentials like industry certifications, licenses, or associate degrees. The credit equals 20% of qualified training expenses (after accounting for previous years' spending), with a special 10% rate for businesses with no prior training costs. Small businesses with under $5 million in annual revenue can elect to apply part of this credit against payroll taxes instead of income tax. Qualified training must be provided through approved channels like community colleges, apprenticeships, or industry partnerships, and must result in an industry-recognized credential. The bill requires the Department of Labor to define "recognized postsecondary credential" within one year of enactment.
