How Long is the IRS Taking to Approve Form 1023 Applications for Exemption?

Question:  If my nonprofit corporation files its IRS Form 1023 today, how long will it take before the IRS issues a letter approving the corporation as a tax-exempt Section 501(c) charitable organization?

Answer:  See the the IRS’ web page called “Where Is My Exemption Application?” to determine how far behind the IRS is in reviewing applications for tax-exemption.  We know of organizations that have received favorable IRS determination letters as quickly as six weeks and as long as two years after submitting applications for tax exemption.
