The reporting of pay is done using the form «Lønns- og trekkoppgave» RF-1015 (so far in Norwegian version only), where, among other things, information must be provided about the employer, employee, gross pay, other remuneration and the tax deducted.
A separate list of codes for filling in «Lønns- og trekkoppgave» can be obtained by contacting the International Tax Collection Authority. Employers must also submit the «Accompanying form» (RF-1025), specifying the total amount of pay and similar reported and the total amount of tax deducted.
