2025 marks a new era in tax compliance, as the Independent Authority for Public Revenue (AADE) activates a strong framework of controls to combat tax evasion.
Businesses and freelancers will now operate under constant digital surveillance as four key changes reshape the tax landscape:
- Locked VAT Returns - No more discrepancies
- Digital Customer Log - Real-time transaction recording
- Digital Shipment Note - Complete tracking of goods movement
- Changes to E3 - Restriction on inflated expenditure
These measures enhance transparency, eliminate the possibility of falsifying tax data and allow the AADE to carry out automated checks on every business activity.
1. Locked VAT Returns: total transparency on declared transactions
Until 2024, businesses had a margin of deviation of up to 30% between their income and expenses in their VAT returns, allowing manipulation of financial data.
What changes in 2025:
- From October 2024: The deviations are reduced to 5% for expenses and to 0% for revenue.
- From January 2025: Each business submits VAT returns exclusively through myDATA, without the possibility of amendment.
- Automatic controls: Any discrepancy will immediately trigger audit notifications from the Hellenic Revenue Authority.
This change puts an end to practices of overcharging and revenue concealment, enhancing tax compliance.
2. Digital Client Catalogue: Recording of Customers and Transactions
The ADPE now acquires a complete picture of business transactions, controlling the flow of customers and receipts in real time.
Obligations of Enterprises:
- Record each customer served.
- Compulsory admission Customer VAT number for invoice transactions.
- Matching evidence of actual transactions.
Which sectors are the first to implement the measure:
✔ Car workshops
✔ Vehicle rental companies
✔ Parking spaces
✔ Car washes
From January 2025, compliance with the Digital Customer Catalogue becomes compulsory and will gradually be extended to more sectors.
3. Digital Dispatch Note: Total Traceability in the Transport of Goods
Tax evasion through undeclared movement of goods is addressed by the introduction of the Digital Dispatch Note, which makes it mandatory electronic recording of every movement of goods through myDATA.
Implementation timetable:
📌 From 1 April 2025 - Mandatory for businesses with a turnover of more than 200.000 euros, as well as for specific sectors such as:
- Pharmaceutical & medical products
- Energy products
- Building materials
- Trade in olive oil
📌 From 1 October 2025 - Extension to all businesses, irrespective of turnover or sector.
What non-compliance entails:
❌ Fine 5.000€ for companies using the accounting system.
❌ A fine of 10.000€ for enterprises with a double-entry accounting system.
With this measure, the ADPE will be able to cross-check in real time the routing and final delivery of goods, preventing smuggling and black market phenomena.
4. New Changes in E3: Strict Control on Expenditure
The form E3 of the tax return becomes a tool for strict control of business expenses.
What changes:
- Imported from pre-completed revenue and expenditure codes to curb over-declared expenditure.
- Although these codes are not locked, from 2025, any deviation will be checked automatically.
- Essentially, the AADE sets limits on the ability of businesses to show fictitious expenses to reduce their tax liability.
Digital Age in Tax Compliance
The transition to the new digital environment leaves no room for tax evasion:
✅ The VAT returns lock and shall not be subject to arbitrary modifications.
✅ The flow of transactions recorded automatically, limiting the potential for revenue concealment.
✅ The movement of goods digitally controlled, preventing illegal activities.
With these measures, the Hellenic Revenue Service is shaping a new, more stringent a fully transparent tax framework. Businesses need to adapt immediately as the digital age of tax compliance is now a reality.
