Excerpts taken from the information prepared by the Tax Practice Improvement Committee Working Group on Document Retention.
Accounting firms are advised to adopt a written retention policy, share it with all firm personnel, and inform clients of the retention policy. Accounting firms are further advised to obtain the necessary legal counsel to ensure that various federal, state and local regulatory requirements are met. Not only should firms consider the state in which they reside, but also states where significant clients are located.
General Guidelines
-Internal Revenue Service and Other Regulatory Body Requirements
An important aspect of an accounting firm's overall document retention policy is obviously compliance with Internal Revenue Service and other regulatory body requirements since all taxpayers are required to keep books and records sufficient to establish the amount of gross income, deductions, credits, or other matters required to be shown by the taxpayer in a tax return.1
For federal income tax purposes, books and records are required to be retained so long as the contents may become material in the administration of the tax laws, although "material" is not defined. For practitioners this generally means information relied on in the preparation of the clients' returns. The books and records must be retained, at a minimum, until the expiration of the statute of limitations, including extensions, for each tax year.2
The IRS has issued guidance with respect to computer document retention and electronic document storage, applicable to both business and individual taxpayers whose tax records are computerized or electronically stored.
Published guidance specifies the basic retention and documentation requirements that the IRS considers to be essential in cases where a taxpayer's books and records are maintained within a computerized system.3 Recommendations for document management and maintenance also are provided. The requirements pertain to all tax matters, including income, excise, employment, and estate and gift taxes, as well as employee plans and exempt organizations.
Although applicable specifically to taxpayers with assets of $10 million or more and other taxpayers who maintain computerized records not available in hardcopy, much of the computer document retention guidance addresses business taxpayers. The IRS routinely reminds business taxpayers of their responsibilities for computer document retention at the beginning of an audit.4
The taxpayer must maintain and make available to the IRS, upon request, documentation of the processes that:
1. create the retained books and records;
2. modify and maintain the books and records;
3. provide sufficient information to support and verify entries made on the taxpayer's return and to determine the correct tax liability; and
4. evidence the authenticity and integrity of the taxpayer's books and records.
The taxpayer must provide, at the time of an examination, the resources that the IRS determines are necessary to process the taxpayer's computer books and records.
The IRS has provided guidance on the maintenance of books and records on an electronic storage system that either images hardcopy or transfers computerized books and records to electronic storage media.5 Books and records maintained in an electronic storage system that complies with the IRS requirements will constitute books and records as required by the tax law and regulations.
The general requirements are that an electronic storage system must:
1. ensure an accurate and complete transfer, indexation, storage, preservation, retrieval and reproduction of the hardcopy or computerized books and records;
2. include reasonable controls, and an inspection and quality assurance program to ensure the integrity, accuracy, reliability, and security of the system;
3. the ability to reproduce legible and readable hardcopies; and
4. provide support for the taxpayer's books and records.
The taxpayer must provide, at the time of an examination, the resources that the IRS determines are necessary to process the taxpayer's computer books and records.
Destruction of hardcopy books and records and deletion of original computerized records are permitted after testing of the system is completed and procedures are implemented to ensure compliance with IRS guidance. In any case, books and records must be retained, at a minimum, until the expiration of the statute of limitations, including extensions, for each tax year.
