The American Rescue Plan Act of 2021 allows small and midsized employers to get a payroll tax credit for wages paid to employees who are not able to work due to COVID-19. This act includes leave taken to get the COVID vaccine or to recover from symptoms related to the vaccine.
These credits are available through 9/30/2021.
