The amount of the deduction referred to in Article L. 5212-10-1 resulting from the conclusion of contracts for supplies, subcontracting or provision of services with adapted companies, establishments or services providing assistance through work, disabled self-employed workers or with employee portage companies when the ported employee is recognised as benefiting from the employment obligation provided for in Article L. 5212-13 is calculated by applying a rate of 30% to the pre-tax price of the supplies, work or services set out in the contract, from which are deducted the costs of raw materials, products, materials, sub-contracting, intermediate consumption and sales and marketing costs.
When the employer employs less than 50% of the rate mentioned in article L. 5212-2 of disabled workers benefiting from the employment obligation in its workforce, the employer may subtract from the amount of its contribution the deduction mentioned in the previous paragraph up to a limit of 50% of the amount of the contribution calculated in accordance with the provisions of article D. 5212-20. This limit is increased to 75% when the group employs at least 50% of the rate mentioned in article L. 5212-2 of beneficiaries of the employment obligation in its workforce.
In the case of contracts concluded by a purchasing group, the amount of the deduction is divided between the various employer members of the purchasing group in proportion to their respective expenditure.
