so presumably they'll just expand that.
Note here from 2007 ? in connection with taxation of Cuban employees of foreign jv's :
Cuba to start collecting income tax on joint venture laborers.
Cuba on Friday said it will allow foreign companies to pay Cuban employees with hard currency, a move that legalizes widespread “under the table” payments and requires workers to declare and pay tax on that income.
Cubans have lived virtually free of taxes for three decades, so for many of those employed by foreign companies, filing annual income tax returns will come as a shock.
<..............continues on the subject of “paladares" :
The National Tax Office was set up in 1995 and the next year began taxing the hard currency income of self-employed Cubans, mainly family restaurants known as “paladares,” the closest thing to a small private business in Cuba.
Their taxes must be paid in hard currency according to a scale that rises as high as 40 percent.
