N.M. Code R. § 3.5.14.9
The denominator of the payroll factor is the total compensation paid everywhere during the tax period. Accordingly, compensation paid to employees whose services are performed entirely in a state where the taxpayer is immune from taxation, for example, by Public Law 86-272, are included in the denominator of the payroll factor.
