myDATA: Common Mistakes and How to Fix Them

The myDATA platform has now become part of everyday operations for every business in Athens and beyond. However, the most common issues arise in the transmission of invoices, the classification of income and expenses, and discrepancies between accounting records and the platform. Incorrect categorization, delayed submissions, or documents that are not properly uploaded can create problems in VAT reconciliation and tax reporting obligations, especially as deadlines approach.

E1: What to Check Before Submission

The E1 tax return is one of the most important obligations for every taxpayer, and proper preparation before submission can significantly impact the final result. Before finalizing the declaration, it is essential to review income, imputed income criteria, expenses, withholdings, and pre-filled data provided by the tax authority (AADE), in order to avoid errors that may lead to unfair taxation or the need for amended returns.

E9: When to Submit an Amendment

The E9 form relates to real estate ownership and must be accurately maintained, as it directly affects the calculation of property-related taxes. An amended E9 declaration is required whenever there is a change in property status, such as purchase, sale, parental transfer, inheritance, correction of square meters, changes in ownership percentages, or any updates to property details that must be properly recorded with the tax authority.
