Payment of Contributions

As a reminder, reports and contributions are due and payable at the bank by the 15th of the month following the work month, and are delinquent if not received at the bank by the 20th (you are urged to contribute at least the 401(k) deferrals by the 15th business day). Failure to report and pay timely, or issuance of a non-sufficient funds check, will result in assessment of Liquidated Damages and Interest Charges. Receipt at the bank is what determines when your contributions were “received”; the postmark is not a factor. Please be mindful and allow sufficient time for mail service and delivery.
