Employer
(2) Employer(i) In general. An employer substantiates its business/investment use of listed property by showing either (A) That, based on evidence that satisfies the requirements of section 274(d) or statements submitted by employees that summarize such evidence, all or a portion of the use of the listed property is by employees in the employer's trade or business and, if any employee used the property for personal purposes, the employer included an appropriate amount in the employee's income, or (B) In the case of a vehicle, the employer treats all use by employees as personal use and includes an appropriate amount in the employees' income. (ii) Reliance on employee records. For purposes of substantiating the business/investment use of listed property that an employer provides to an employee and for purposes of the information required by paragraph (d)(2) and (3) of this section, the employer may rely on adequate records maintained by the employee or on the employee's own statement if corroborated by other sufficient evidence unless the employer knows or has reason to know that the statement, records, or other evidence are not accurate. The employer must retain a copy of the adequate records maintained by the employee or the other sufficient evidence, if available. Alternatively, the employer may rely on a statement submitted by the employee that provides sufficient information to allow the employer to determine the business/investment use of the property unless the employer knows or has reason to know that the statement is not based on adequate records or on the employee's own statement corroborated by other sufficient evidence. If the employer relies on the employee's statement, the employer must retain only a copy of the statement. The employee must retain a copy of the adequate records or other evidence.
