Is expanded by the October 1st The cycle of business and of their professional they can submit – optionally in the first phase – monthly statements VAT.

This is, as the ERTfor the second stage of implementation of the new regime of monthly statements. The first application, which began on July 1, 2025, involved 92,590 businesses and freelancers starting activity from January 1, 2024 to March 31, 2025. Night is now being taken by businesses that have kept simplistic books and have begun their activity by December 31, 2023.

Including the new regime will initially be optional, but in the future it will become mandatory for all businesses and freelancers, radically changing VAT, a tax that is the main source of revenue for the state budget.

As AADE points out, the gradual transition to monthly statements is expected to improve taxability of taxes and provide the state with the possibility of closely monitoring real economic activity.

It is recalled that the first “group” of the debtors who joined the new regime was the operations set up in 2024 and until the first quarter of 2025. Regardless of whether they adhere to simplified or duplicate books, they are required to file monthly VAT statements, instead of the older quarterly system. However, after 24 months after the start of their work, they may return to quarterly submission if they wish.

The monthly VAT statement is characterized as one of the most effective tools of tax administration, as:

  • Provides an immediate image of business inputs and outflows
  • Restricts the risk of delays and accumulation of debt
  • Allows faster detection of irregularities

‘Bloc’ in tax evasion

With the full implementation of the Mydata platform, the submission of monthly VAT declarations is now incorporated by the electronic transmission of documents, marking a new era of “electronic accounting” in Greece. At the same time, the introduction of monthly submission contributes substantially to the fight against tax evasion, preventing cases of businesses that, after a short period of operation, interrupt their operations without fulfilling their tax liabilities.

The sharp increase in electronic transactions, coupled with changes in the process of submitting VAT statements, is expected to significantly reduce the so -called “vacuum VAT”, that is, the losses that the state suffers from non -tax return. In 2024, the lost VAT rate was estimated at 10%, reduced by 13.7% in 2022, and is projected to fall to about 7% within two years. It is estimated that if Greece approached the EU average, estimated at about 5%, the state would have a benefit of about € 1.4 billion.
