Are PTAs allowed by the IRS to keep electronic copies of their records?
All requirements that apply to hard copy books and records also apply to electronic storage systems that maintain tax books and records. When you replace hard copy books and records, you must maintain the electronic storage systems for as long as they are material to the administration of tax law.
An electronic storage system is any system for preparing or keeping your records either by electronic imaging or by transfer to an electronic storage media. The electronic storage system must index, store, preserve, retrieve, and reproduce the electronically stored books and records in a legible, readable format. All electronic storage systems must provide a complete and accurate record of your data that is accessible to the IRS. Electronic storage systems are also subject to the same controls and retention guidelines as those imposed on your original hard copy books and records.
The original hard copy books and records may be destroyed provided that the electronic storage system has been tested to establish that the hard copy books and records are being reproduced in compliance with IRS requirements for an electronic storage system and procedures are established to ensure continued compliance with all applicable rules and regulations. You still have the responsibility of retaining any other books and records that are required to be retained.
For details on electronic storage system requirements, see Rev. Proc. 97-22, which is on page 9 of Internal Revenue Bulletin 1997-13 at www.irs.gov/pub/irs-irbs/irb97-13.pdf.
