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.
Ad. 2. Determine what form to file. The tax return your nonprofit will file largely depends on the amount of money your organization made in the applicable tax year. 1  The general form number that a nonprofit will file is form 990, although there are variations of this form.ven if a nonprofit organization has achieved tax-exempt status, for example under Section 501(c)(3), the organization is likely still required to file a tax return annually.
