The acquisition by Orange transformed Mobistar into an international telecommunications operator. As a result, the company now has employees from over 46 countries where a special tax regime applies to these workers.
"Expatriate payroll management can be complicated and time-consuming. If there are fifty expatriates, you need to perform the same number of different payroll calculations. The My International Employment application makes that a thing of the past." Nathalie Villers, HR Legal Advisor at Orange Belgium
The challenge
No 'one size fits all'
The international payroll team at Orange Belgium, formerly Mobistar, had to put a lot of pressure the telecommunications company's HR department.
"In Belgium, expatriates are not taxed on foreign income. As such, they are subject to different payroll calculations. Add the differences due to local legislation in the country of origin and you are dealing with a very complex payroll."
Orange Belgium already relied on SD Worx to do the payroll processing for its Belgian employees. "Payroll calculations for expatriates were carried out by another service provider. Such calculations were not performed automatically in our local payroll administration system. An HR employee therefore had to enter all the data by hand again for each employee. A time-consuming task." - Nathalie Villers, HR Legal Advisor at Orange Belgium
Orange was therefore looking for an alternative.
Tailored payroll
SD Worx proposed a tailor-made solution for Orange Belgium: automatic payroll integration with the existing payroll platform. "The system contains all the specific tax systems for the expatriate payroll. This allows us to calculate each different regime accurately."
The results
Fewer mistakes, more focus
This integrated approach has provided Orange with many benefits: "Automating the expatriate payroll administration limits errors due to manual input and enables HR employees to focus on more strategic tasks. In addition, there is a team of experts available to answer any questions expatriates may have relating to international employment. No unwarranted luxury in such a complex HR environment."
