Greetings and blessings, Sue. As a tax CPA, we have a general rule to keep important financial data on a 10 year roll. This may be overkill, but it's an easy number to remember. I've had issues with the IRS that have required 8 year look back by the time the issue developed and resolved. Not with a nonprofit, but still the IRS is not very current when getting around to questioning something. Technically, they only have 3 years to ask, but if the issue reaches back, it's on you to defend your response with backup reaching back to support the issue. Sorry for the long response. Also, keep all actual filed returns permanently.
