Greece is preparing to present a list of reforms to lenders in order to secure a bailout extension.
The list to be submitted on Monday must be approved by international creditors to secure a four-month loan extension.
Analysts say a collapse of the deal would revive fears of a Greek exit from the euro.
Minister of state Nikos Pappas said the list would include measures to tackle tax evasion and streamline the civil service.
Germany’s Bild daily newspaper, citing an unnamed source, reports that Greece aims to recover 7.3bn euros (£5.4bn; $8.3bn) with measures to combat tax evasion.
