Questions on account numbers and tax preparers are answered. Subsection 4.1.4 of NACHA Operating Rules indicates that you, as the Receiving Depository Financial Institution, may rely solely on the account number contained in (an) entry for purposes of posting the entry to (a) Receiver's account. So there is no rule requiring you to refuse these entries. However, unless you want to risk problems in the future, you simply should not permit this direct deposit to continue. The tax preparer does not meet the Bank Secrecy Act definition of a check casher if he only cashes his own tax refund anticipation loan checks for taxpayers for whom he has prepared tax returns. This activity is equivalent to disbursing loan proceeds with cash.
