An employer is a semi weekly depositor of federal employment taxes for the entire calendar year if the aggregate amount of taxes reported on Form 941 (Employer's Quarterly Federal Tax Return) during the look back period (twelve month period ended June 30, of the previous year) exceeded $50,000. A monthly depositor will become a semi weekly depositor for the first day after the employer becomes subject to the Accelerated Deposit Rule.
Semi weekly deposits are generally due on either Wednesday or Friday depending upon the timing of the employer's pay period. Employers with pay days that fall on Wednesday, Thursday, or Friday must deposit employment taxes on or before the following Wednesday. Employers with pay days that fall on Saturday, Sunday, Monday, or Tuesday must deposit employment taxes on or before the following Friday. An employer always has three banking days in which to make the deposit. More information can be found on page 20 of IRS Publication 15.
