When must 401(k) salary deferrals be deposited in the trust?
The Department of Labor directs that deferrals be deposited as soon as administratively feasible following the date they are withheld from employee paychecks. This means the earliest date by which the withheld deferrals can be segregated from the general assets of the employer. The maximum permitted time period (which now appears to be applicable only under exceptional circumstances) is 15 days following the date deferrals are withheld from employee paychecks.
