A sample tax exempt letter is available at FinWeb.com. The Internal Revenue Service provides the information requirements for affirmation letters pertaining to tax exempt organizations on its website.
A tax exempt letter establishes an organization as tax exempt. Tax exempt organizations write affirmation letters to confirm tax exempt status or due to a name or address change, according to the IRS. The government grants an organization tax exempt status after the organization successfully completes the not-for-profit application process, explains FinancialWeb. Most nonprofit organizations are educational, charitable or religious in nature. Tax exempt letters should include the organization's name, contact information, reason for exemption status and intended benefits.
