In Greece, taxpayers who will submit the preliminary E3 form have up to 30% leeway to modify the pre-filled data on their reported revenues, while they can also increase the pre-filled amounts for deductible expenses. However, any reduction in the revenue section or any addition in deductible expenses must correspond with data transmitted through the myData platform, which serves as the electronic tax record system. This year, approximately 1.5 million businesses, freelancers, and farmers will be filing the E3 form, which reflects their income and expense data as reported to the tax authorities.

The E3 form is crucial for tax reporting in Greece, as it encapsulates the financial activities of numerous entities. The scope for alterations is significant when it comes to increasing taxable revenues and reducing deductible expenses, allowing taxpayers some flexibility. Nonetheless, the reduced flexibility with a cap of 30% for lowering taxable revenues and increasing deductible expenses indicates a structured approach by the tax authority to maintain accuracy in tax reporting and correlate with the myData system.

This regulation highlights the emphasis on digital tax administration in Greece, increasingly relying on electronic systems for compliance. The move towards a more regulated approach in tax reporting underscores the efforts of the Greek tax authority, AADE (Independent Authority for Public Revenue), to streamline tax processes and reduce discrepancies, which are essential steps toward improving tax collection and compliance.
