    Since 2021, all companies in Spain, regardless of size, must have an updated salary register. It is not optional and the Labor Inspectorate can request it at any time.

    What is it?

    A document recording average salary values, supplements and extra-salary payments, broken down by sex and professional category (Royal Decree 902/2020).

    Purpose

    To detect and correct pay inequalities between men and women. If the average difference exceeds 25% in the same category, the company must justify it with objective causes.

    How to create it

    Collect all pay concepts and calculate averages and medians by sex for each group. Reference period is the calendar year. An HR management system that centralizes payroll information makes this much easier.
