150-314-0265 Model Recordkeeping and Retention (1) Definitions. For purposes of this rule, these terms shall be defined as follows: (a) “Database management system” means a software system that controls, relates, retrieves, and provides accessibility to data stored in a database. (b) “Electronic data interchange” or “EDI technology” means the computer-to-computer exchange of business transactions in a standardized structured electronic format. (c) “Hard copy” means any documents, records, reports or other data printed on paper. (d) “Machine-sensible record” means a collection of related information in an electronic format. Machine-sensible records do not include hard-copy records that are created or recorded on paper or stored in or by an imaging system such as microfilm, microfiche, or storage-only imaging systems. (e) “Storage-only imaging system” means a system of computer hardware and software that provides for the storage, retention and retrieval of documents originally created on paper. It does not include any system, or part of a system, that manipulates or processes any information or data contained on the document in any manner other than to reproduce the document in hard copy or as an optical image. (f) “Taxpayer” as used in this rule means any natural person, estate, trust, or beneficiary whose income is in whole or in part subject to the taxes administered by the department that tie to provisions in ORS chapter 314. (2) Recordkeeping Requirement — General: (a) A taxpayer shall maintain all records that are necessary to a determination of the correct tax liability under tax laws of this state that are administered by the department that tie to provisions in ORS chapter 314. All required records shall be made available on request by the department or its authorized representatives as provided for in ORS 314.425. (b) If a taxpayer retains records required to be retained under this rule in both machine-sensible and hard-copy formats, the taxpayer shall make the records available to the department in machine-sensible format upon request of the department. (c) Nothing in this rule shall be construed to prohibit a taxpayer from demonstrating tax compliance with traditional hard-copy documents or reproductions thereof, in whole or in part, whether or not such taxpayer also has retained or has the capability to retain records on electronic or other storage media in accordance with this rule. However, this subsection shall not relieve the taxpayer of the obligation to comply with subsection (2)(b) of this rule. (3) Recordkeeping Requirements — Machine-Sensible Records: (a) General Requirements: (A) Machine-sensible records used to establish tax compliance shall contain sufficient transaction-level detail information so that the details underlying the machine-sensible records can be identified and made available to the department upon request. A taxpayer has discretion to discard duplicated records and redundant information provided its responsibilities under this rule are met. (B) At the time of an examination, the retained records shall be capable of being retrieved and converted to a standard record format. (C) Taxpayers are not required to construct machine-sensible records other than those created in the ordinary course of business. A taxpayer who does not create the electronic equivalent of a traditional paper document in the ordinary course of business is not required to construct such a record for tax purposes. (b) Electronic Data Interchange Requirements: (A) Where a taxpayer uses electronic data interchange processes and technology, the level of record detail, in combination with other records related to the transactions, shall be equivalent to that contained in an acceptable paper record. For example, the retained records should contain such information as vendor name, invoice date, product description, quantity purchased, price, amount of tax, indication of tax status, shipping detail, etc. Codes may be used to identify some or all of the data elements, provided that the taxpayer provides a method which allows the department to interpret the coded information. (B) The taxpayer may capture the information necessary to satisfy subsection (3)(b)(A) at any level within the accounting system and need not retain the original EDI transaction records provided the audit trail, authenticity, and integrity of the retained records can be established. For example, a taxpayer using electronic data interchange technology receives electronic invoices from its suppliers. The taxpayer decides to retain the invoice data from completed and verified EDI transactions in its accounts payable system rather than to retain the EDI transactions themselves. Since neither the EDI transaction nor the accounts payable system captures information from the invoice pertaining to product description and vendor name (i.e., they contain only codes for that information), the taxpayer also retains other records, such as its vendor master file and product code description lists and makes them available to the department. In this example, the taxpayer need not retain its EDI transaction for tax purposes. (c) Electronic Data Processing Systems Requirements — The requirements for an electronic data processing accounting system should be similar to that of a manual accounting system, in that an adequately designed accounting system should incorporate methods and records that will satisfy the requirements of this rule. (d) Business Process Information: (A) Upon the request of the department, the taxpayer shall provide a description of the business process that created the retained records. Such description shall include the relationship between the records and the tax documents prepared by the taxpayer and the measures employed to ensure the integrity of the records. (B) The taxpayer shall be capable of demonstrating: (i) The functions being performed as they relate to the flow of data through the system; (ii) The internal controls used to ensure accurate and reliable processing; and (iii) The internal controls used to prevent unauthorized addition, alteration, or deletion of retained records. (C) The following specific documentation is required for machine-sensible records retained pursuant to this rule: (i) Record formats or layouts; (ii) Field definitions (including the meaning of all codes used to represent information); (iii) File descriptions (e.g., data set name); and (iv) Detailed charts of accounts and account descriptions. (4) Records Maintenance Requirements: (a) The department recommends but does not require that taxpayers refer to the National Archives and Record Administration’s (NARA) standards for guidance on the maintenance and storage of electronic records, such as the labeling of records, the location and security of the storage environment, the creation of back-up copies, and the use of periodic testing to confirm the continued integrity of the records. (b) The taxpayer’s computer hardware or software shall accommodate the extraction and conversion of retained machine-sensible records. (5) Access to Machine-Sensible Records: (a) The manner in which the department is provided access to machine-sensible records as required in subsection (2)(b) of this rule may be satisfied through a variety of means that shall take into account a taxpayer’s facts and circumstances through consultation with the taxpayer. (b) Such access will be provided in one or more of the following manners: (A) The taxpayer may arrange to provide the department with the hardware, software and personnel resources to access the machine-sensible records. (B) The taxpayer may arrange for a third party to provide the hardware, software and personnel resources necessary to access the machine-sensible records. (C) The taxpayer may convert the machine-sensible records to a standard record format specified by the department including copies of files, on a magnetic medium that is agreed to by the department. (D) The taxpayer and the department may agree on other means of providing access to the machine-sensible records. (6) Taxpayer Responsibility and Discretionary Authority: (a) In conjunction with meeting the requirements of section (3) of this rule, a taxpayer may create files solely for the use of the department. For example, if a database management system is used, it is consistent with this rule for the taxpayer to create and retain a file that contains the transaction-level detail from the database management system and that meets the requirements of section (3) of this rule. The taxpayer should document the process that created the separate file to show the relationship between that file and the original records. (b) A taxpayer may contract with a third party to provide custodial or management services of the records. Such a contract shall not relieve the taxpayer of its responsibilities under this rule. (7) Alternative Storage Media: (a) For purposes of storage and retention, taxpayers may convert hard-copy documents received or produced in the normal course of business and required to be retained under this rule to microfilm, microfiche or other storage-only imaging systems and may discard the original hard-copy documents, provided the conditions of this section are met. Documents which may be stored on these media include, but are not limited to general books of account, journals, voucher registers, general and subsidiary ledgers, and supporting records of details, such as sales invoices, purchase invoices, exemption certificates, and credit memoranda. (b) Microfilm, microfiche and other storage-only imaging systems shall meet the following requirements: (A) Documentation establishing the procedures for converting the hard-copy documents to microfilm, microfiche or other storage-only imaging system shall be maintained and made available on request. Such documentation shall, at a minimum, contain a sufficient description to allow an original document to be followed through the conversion system as well as internal procedures established for inspection and quality assurance. (B) Procedures shall be established for the effective identification, processing, storage, and preservation of the stored documents and for making them available for the period they are required to be retained under section (9) of this rule. (C) Upon request by the department, a taxpayer shall provide facilities and equipment for reading, locating, and reproducing any documents maintained on microfilm, microfiche or other storage-only imaging system. (D) When displayed on such equipment or reproduced on paper, the documents shall exhibit a high degree of legibility and readability. For this purpose, legibility is defined as the quality of a letter or numeral that enables the observer to identify it positively and quickly to the exclusion of all other letters or numerals. Readability is defined as the quality of a group of letters or numerals being recognizable as words or complete numbers. (E) All data stored on microfilm, microfiche or other storage-only imaging systems shall be maintained and arranged in a manner that permits the location of any particular record. (F) There is no substantial evidence that the microfilm, microfiche or other storage-only imaging system lacks authenticity or integrity. (8) Effect on Hard-Copy Recordkeeping Requirements: (a) Except as otherwise provided in this section, the provisions of this rule do not relieve taxpayers of the responsibility to retain hard-copy records that are created or received in the ordinary course of business as required by existing law and rules. Hard-copy records may be retained on a recordkeeping medium as provided in section (7) of this rule. (b) If hard-copy records are not produced or received in the ordinary course of transacting business (e.g., when the taxpayer uses electronic data interchange technology), such hard-copy records need not be created. (c) Hard-copy records generated at the time of a transaction using a credit or debit card shall be retained unless all the details necessary to determine correct tax liability relating to the transaction are subsequently received and retained by the taxpayer in accordance with this rule. Such details include those listed in subsection (3)(b)-(A). (d) Computer printouts that are created for validation, control, or other temporary purposes need not be retained. (e) Nothing in this section shall prevent the department from requesting hard-copy printouts in lieu of retained machine-sensible records at the time of examination. (9) Records Retention — Time Period — All records required to be retained under this rule shall be preserved pursuant to ORS 314.425 unless the department has provided in writing that the records are no longer required.
