Non - compliance with GDPR can lead to a fine of up to 4 % of global annual revenue , or € 20 m ( $ 22.6 m ) , whichever is higher . However , EU regulators are likely to be lenient if companies have not updated clauses in their contracts immediately after a no - deal Brexit . Furthermore , the majority of GDPR complaints are brought by individuals who may not consider this cause of non - compliance as serious as others .
