Hundreds of thousands of federal employees will likely see the effects of the 2019 pay raise on their next paychecks according to an April 13 notice from the National Finance Center.

Congress passed a 1.9 percent federal employee pay raise in February that would retroactively apply to all pay periods in 2019. President Donald Trump, however, didn’t sign an executive order instructing the Office of Personnel Management to implement the new pay tables until March.

According to the National Finance Center, this means that employees whose paychecks are distributed by its pay program will receive a larger paycheck for the period covering April 1-14.

The National Finance Center, which falls under the authority of the Department of Agriculture but offers pay services for other agencies as well, oversees payroll for more than 650,000 federal employees at 170 federal agencies. Feds covered by another payroll service may therefore see a different timeline for the pay raise’s implementation.

For those that are covered by the National Finance Center, not all will receive the full retroactive pay on their next paycheck. The notice, first reported by Government Executive, stipulates that receipt of the full, retroactive pay depends on whether an action such as a promotion or step increase requires additional paperwork.

“Employees’ retroactive salaries will not be paid until your agency processes a history correction and it revalidates and applies to the Payroll Personnel System in a future pay period,” the National Finance Center’s pay raise timeline said.

Those employees will still see the pay increase reflected in their checks from early April, but not the retroactive funds that apply to their earlier paychecks.
