Deposit your business’s employment taxes for Wednesday, Thursday, and/or Friday payments by the following Wednesday. A semiweekly schedule depositor must also deposit taxes for the Saturday, Sunday, Monday, and/or Tuesday payments by the following Friday. A semiweekly schedule is one of two options for taxes that you report on Forms 941, 943, 944, and 945. The other option is to be a monthly schedule depositor. Deposit your business’s employment taxes on a monthly schedule by the 15th day of the next month.
Figure out which of the two schedules you must use before the start of each calendar year. Your schedule depends on what you reported your business’s total tax liability as during a previous lookback period. The type of form determines your lookback period. Find more information on a form or Publication 15.
