Federal Withholding Tax
There are two Federal Withholding Tax deposit schedules, monthly and bi-weekly. Before the beginning of each calendar year, you must determine which of the two deposit schedules you’ll be required to use. The deposit schedule you must use is based on the total tax liability you reported on Form 941 during a lookback period. Schedules for depositing and reporting federal taxes aren’t the same. You must use electronic funds transfer (EFTPS) to make all federal tax deposits.
