CIAK's unprofessional business practices cost me over €1,000 euros this year. Being a very happy client in the first 2 years I hired CIAK, I was shocked by their deplorable communication about changes to their service offering for 2018 taxes, which resulted in my filing cost to go from €60 in 2016 and 2017 to over €1,000 in 2018. Beware. dsmall | 06-05-2020

ExpatRadar recently spotted a very good recommendation for CIAK's tax compliance work. Their happy client says "I can highly recommend them...they are great"! Expat321 | 05-07-2017
