European Regulation 651/2014 indicates the maximum limits of public aid that can be granted for innovation processes. Depending on whether an applicant is a large enterprise, medium-sized enterprise (less than 250 employees and annual turnover less than EUR 50 million or annual balance sheet total less than EUR 43 million) or small enterprise (less than 50 employees and annual turnover or annual balance sheet total less than EUR 10 million), the limits vary depending on the program.

In Commercial Projects, the subsidy may be up to a maximum of 80% for small companies, up to 75% for medium-sized companies and up to 65% for large companies.

In Pre-Commercial Projects, the subsidy may amount to a maximum of 60% for small companies, up to 50% for medium-sized companies and up to 40% for large companies. In the case of groupings of companies, these percentages refer to each one separately and only to its part of the budget.
