Utah Admin. Code 994-204-201
Employment is covered under the Act if all of a worker's service is performed within Utah. Workers who perform services for one employer in more than one state are covered in Utah under certain circumstances.
The service is considered to be localized in Utah if it is performed entirely within Utah. The service is also considered to be localized in Utah if performed both inside and outside of Utah, but the service outside of Utah consists of isolated transactions or is otherwise incidental or transitory to the service in Utah. Some of the factors which might indicate that the service is incidental or transitory are:
If the service is not localized in any state but some of the service is performed by the worker in Utah, the entire service is covered in Utah if one of the following conditions apply:
The worker's base of operations is in Utah. The "base of operations" is the place from which the worker starts work and to which he or she customarily returns for instructions from the employer, communications from customers, to replenish stocks or materials, to repair equipment or to perform any other function necessary in the trade or profession. The base of operations may be the worker's business office, which may be located at his or her residence, or the contract of employment may specify a particular place at which the worker is to receive direction and instructions.
If the worker has no base of operations or does not perform any service in the state in which the base of operations is located, it is necessary to determine if any service is performed in the state from which the service is controlled or directed. The place from which the service is controlled or directed is the place at which the basic authority exists rather than the place at which a manager or foreman supervises the service.
If the conditions in paragraphs (a) or (b) of this subsection do not apply, it is necessary to apply the test of residence. Under this test, the service is covered in Utah if the worker lives in Utah and performs some of his or her services in Utah.
If the service is not localized in any state and none of the service is performed by the worker in Utah, the entire service is covered in Utah if one of the following conditions apply:
The worker's base of operations is in Utah. The "base of operations" is the place from which the worker starts work and customarily returns for instructions from the employer, to replenish stocks or materials, to repair equipment or to perform any other function necessary in the worker's trade or profession. The base of operations may be the worker's business office, which may be located at his or her residence, or the contract of employment may specify a particular place at which the worker is to receive his or her direction and instructions.
If the worker has no base of operations or does not perform any service in the state in which the base of operations is located, it is necessary to determine if the worker is controlled and directed from Utah. The place from which the service is controlled or directed is the place at which the basic authority exists rather than the place at which a manager or foreman supervises the service.
If after applying all of the above tests to a given set of circumstances, the worker's service is found not to be subject to any one state, the employer may elect to cover all of the worker's service in one state. This election must be made under the provisions for reciprocal coverage arrangements found in Section 35A-4-106. The Department will approve reciprocal coverage and allow an employer to cover a worker's entire service in Utah if:
