If your church or organization reported withheld taxes of $50,000 or less during the most recent lookback period (for 2020 the lookback period is July 1, 2018, through June 30, 2019), then withheld payroll taxes are deposited monthly. Monthly deposits are due by the 15th day of the following month.
Note, however, that if withheld taxes are less than $2,500 at the end of any calendar quarter (March 31, June 30, September 30, or December 31), the church need not deposit the taxes. Instead, it can pay the total withheld taxes directly to the IRS with its quarterly Form 941. Withheld taxes include federal income taxes withheld from employee wages, the employee's share of Social Security and Medicare taxes, and the employer's share of Social Security and Medicare taxes.
