Using estimation results, the size of shadow economy is assessed. According to the estimates shadow economy declined in the period 1995–2007 starting from 40% of GDP in 1995 and reaching about 10% of GDP in 2007. The paper also analyses relations between shadow economy, state budget and tax system.
