Most nonprofits and charities must keep books and records for a minimum of six years from the end of the last tax year to which they relate. This retention period will be extended if returns are late-filed or if there is a notice of objection or appeal underway.
Some common nonprofits that aren't required to file any informational tax returns include tax-exempt, faith-based organizations, religious schools, missions and missionary organizations. Subsidiaries of other tax-exempt nonprofits are also exceptions. Subsidiaries are groups formed under a larger parent organization.hey are required to file an annual informational tax return for purposes of letting the IRS know about their revenues, expenses, activities and administration. Non-exempt organizations pay income tax at the standard corporate rate.
