All Ukrainian migrant workers will pay taxes to the state

The State Tax Service believes that the majority of Ukrainians who went to work abroad do not declare their income and do not pay taxes in Ukraine. 
As Oleksiy Lyubchenko, the head of the State Tax Service, said in an interview with the NV magazine, taxes must be paid on all income from Ukrainian migrant workers. 
"Of the $ 12 billion that comes to Ukraine from those, who left to work abroad, only 11 billion but hryvnias – ie 30 times less – is declared. Everyone must file a declaration," – Oleksiy Lyubchenko said.  
However, the head of the State Tax Service did not specify what the tax rate would be and how migrant workers would be taxed.
