The country's tax authorities have been performing 52 confiscations an hour, or almost one every minute, seizing the bank accounts of salary workers, pensioners and corporations.

The tax administration is asking the country's banks to provide details of all transactions since 2015 concerning the accounts of taxpayers who are under investigation.

High income taxation rates, combined with "extraordinary" tax levies, such as the solidarity levy and the Single Property Tax (ENFIA), have exhausted Greek households, many of which are in a losing battle with the taxman as they helplessly watch their debts increase.

The tax administration estimates this year's collections from expired dues to come to 6.5 billion euros, noting that debt arrangements and asset confiscations will boost revenues, after coming to 4 billion euros by end-September.

Enterprises and self-employed people who fail to declare a professional or corporate bank account to the tax authorities are set to face hefty fines.

Greece's state budget achieved a primary budget surplus of 2.08 billion euros in the first seven months of the year, more than double the planned 929 million euros, but investments and tax refunds were well below target, according to the Finance Ministry's preliminary budget execution bulletin published on Tuesday.

Taxpayers' expired arrears to the state soared to 5.19 billion euros in the first half of the year - that is before the heavy tax obligations started in July. At the same time, the monitoring mechanism has been confiscating or freezing about 360 bank accounts per day, although it is increasingly finding empty accounts.

While the process for the submission of income tax declarations was completed on Monday and Tuesday is the deadline for the first installment, all signs point to revenues being about half a billion euros less than last year.

The Trump administration is freezing payments under an "Obamacare" program that protects insurers with sicker patients from financial losses, a move expected to add to premium increases next year.

The overdue arrears of individual taxpayers and corporations to the state climbed to 4.15 billion euros after the first four months of the year, as the growth rate continues to be about 1 billion euros per month, meaning that by the end of the year new debts to the state will likely exceed 12 billion.
