Hi @taxdummy69
Wow, what an incentive to get vaccinated!
While the vaccine incentives aren't paid as part of an hourly rate, they are a form of job-based compensation. Since the payments are considered salary/wages, the employer needs to gross it up at each employee's marginal tax rate. They will also be superable as Ordinary Time Earnings.
The payments will not be fringe benefits.
