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.
1 Typically, the IRS can come after your business for failing to report income for up to 6 years after your filing if the amount is greater than 25% of your businessâs gross income. 2  If you filed for a deduction for a bad debt or worthless security, the IRS suggests you keep your supporting tax records for 7 years. Excluding employment tax records, files relating to current employees should be retained while they are working for you and at least 7 years after a current or former employee has left or been terminated. 2  For any job applicants who were not eventually hired, keep these files for at least 3 years.
