Regardless of whether an amount is paid to an employee by their state/local government, or by their employer, a payment that is in the nature of compensation for services is not excludable as a qualified disaster relief payment under section 139 of the Code. If you are performing services as an employee, the premium pay is also generally considered wages and is subject to withholding of applicable taxes.

Payments to individuals from SLFRF for utilities (or arranges of utilities) is NOT considered income and therefore a Form 1099-MISC is not required.
