The representative will be the bridge between you and the Tax Authority. You need to be sure that he is able to receive any and all communications on your behalf and inform you in a timely manner.

My wife and I made a decision to start our immigration process in October of 2023. Vivian was recommended to us around that same time.We both appreciate everything Vivian has helped us with through the process. We are now waiting on our visa. Vivian has proved very knowledgeable and without her help, we would have struggled. Her communication has always been excellent and never missed a meeting. We communicated in English with no problems. Her dedication and experience are highly rated by us.
Dr Vivian was incredibly kind to deal with. She is very confident and knows her job very well, preparing my emigration to Portugal. Her vast legal knowledge leaves me safe and confident in future decisions regarding the purchase or rental of property, avoiding the traps and tricks so common in this segment.
