Fiscalist gezocht voor advies/bezwaar ivm 30% ruling expatregeling

Plaats: Rotterdam

Gevraagde diensten: inkomstenbelasting, belastingadvies

Toelichting
I have come to the Netherlands in 2016 when the 30% ruling duration was advertised as 8 years.
In the meantime the duration was reduced to 5 years (also retroactively)
I have logged complaints to Belastingdienst after the 5 years ended, and after quite some time they responded by refusing my complaint.
I want to talk to a tax advisor to see what my next options are.
Thank you for your help!
