Customer liability / exemption certificate

New liability rules for clients awarding construction works have been added to the ASVG with the Employer's Liability Law (§67a - 67d and § 112a General Law on Social Security ASVG). These new liability rules aim to counteract the loss of social security contributions through social security fraud. The Employer's liability came into force on 1 September 2009 by decree of the Federal Ministry of Labour and Social Affairs.
