Entity A and Entity B have the same owners.
Entity A needed an employee for a period of time and Entity B had an employee with spare time available.
The employee rendered services to Entity A, but Entity B paid the employee's salary. Entity A reimbursed Entity B for the employee's net salary.
Should the invoice between Entity A and Entity B carry VAT if both entities are VAT registered? If so, how do I explain this is a VATable supply as salaries as such are not vatable and this is a reimbursement for salary?
