In total, 4,923 taxpayers are being monitored, of which 3,321 are companies and 1,602 are citizens. Large taxpayers represent 40% of the total tax revenue from companies based in Portugal.
According to Jornal de Notícias, the biggest jump in the number of taxpayers monitored took place in 2018, the year in which the legislation was changed to include more companies on the list of those that are under the radar of this special unit of finance.
Until then, for example, companies under the supervision of the Bank of Portugal were only on the UGC list if they had a turnover of more than 100 million euros, according to the summary table of the register of large taxpayers in Portugal in the report on the fight against fraud and tax and customs evasion from 2021. As of 2018, all those under the supervision of the banking regulator, regardless of billing, have been included.
