All companies with private capital  that earned up to 500,000 euros in revenue in 2016 are required to change their tax system by becoming a taxpayer on microfinance income. Basically, no private company with income under this ceiling can not  pay a 16%  tax rate, but is forced to apply the tax regime for micro-enterprises. The only companies that escape this obligation are those with social capital of at least 45,000 lei, who can choose which tax system they apply (micro or profit tax).
