31 CFR §206.5

1. (a)The following collection and deposit timeframe requirements are to be followed in exception cases where EFT mechanisms are not utilized:
   1. (1)An agency will achieve same-day deposit of monies. Where same day deposit is not cost-effective or is impracticable, next day deposit of monies must be achieved except in those cases covered by I TFM 6-8000.
   2. (2)Deposits will be made at a time of the day prior to the depositary's specified cutoff time, but as late as possible in order to maximize daily deposit amounts.
   3. (3)When cost-beneficial to the Government, an agency may make multiple deposits.
2. (b)Any additional exceptions to the above policies are listed in I TFM 6-8000.
