Ministers (who have not elected voluntary withholding) and self-employed workers must file their second quarterly estimated federal tax payment for 2019 by this date. A similar rule applies in many states to payments of estimated state taxes. Nonminister employees of churches that filed a timely Form 8274 (waiving the church’s obligation to withhold and pay FICA taxes) are treated as self-employed for Social Security, and accordingly are subject to the estimated tax deadlines with respect to their self-employment (Social Security) taxes unless they ask their employing church to withhold an additional amount of income taxes from each paycheck that will be sufficient to cover self-employment taxes (use a new Form W-4 to make this request).
An annual information return (Form 990) for tax-exempt organizations is due by this date for 2018. Form 990 summarizes revenue, expenses, and services rendered. Organizations exempt from federal income tax under section 501(c)(3) of the Internal Revenue Code must report additional information on Schedule A. Churches, conventions and associations of churches, “integrated auxiliaries” of churches, and church-affiliated elementary and secondary schools are among the organizations that are exempt from this reporting requirement. Organizations not exempt from this reporting requirement must file the Form 990 if they normally have annual gross receipts of $25,000 or more.
