The Greek government has introduced a new electronic platform eTax called My Digital Accounting and Tax Application (MyDATA) for businesses to submit tax data. This platform is a mandatory requirement for businesses in Greece and will replace the existing electronic tax filing system. In this blog post, we will discuss the details of MyDATA, when it becomes mandatory, how the process works, and how SAP Document and Reporting Compliance can help businesses comply with the new regulations.
What is MyDATA?
myDATA (my Digital Accounting and Tax Application) is an electronic platform developed by the Independent Authority for Public Revenue (IAPR), the Greek tax authority. The platform aims to modernize and simplify the tax compliance process for businesses operating in Greece. By promoting digital record-keeping and electronic reporting of financial transactions, myDATA enhances tax transparency, reduces tax evasion, and improves the overall efficiency of tax administration.
Businesses in Greece are required to register on the myDATA platform, maintain digital records of their financial transactions, submit summarized transaction data to the platform regularly, issue and receive electronic invoices (e-invoices), maintain electronic books (e-books) for accounting records, and adhere to data retention requirements.
By implementing myDATA, the Greek tax authority seeks to create a more streamlined, transparent, and efficient tax system that benefits both taxpayers and the government.
When does MyDATA become mandatory?
The Greek government introduced MyDATA in October 2020, and it will become mandatory for businesses in Greece in 2021. This means that it is already mandatory.
How does the MyDATA process work?
The myDATA process in Greece involves a series of steps that businesses need to follow to ensure compliance with the country’s tax regulations. Here is an overview of how the myDATA process works:
- Registration: Businesses need to register on the myDATA platform using their tax identification number (AFM). Access to the platform is provided through Greece’s TAXISnet system, which is the government’s online tax services portal.
- Digital Record Keeping: Businesses are required to maintain digital records of their financial transactions, including sales and purchase invoices, and expense receipts. These records must include specific information such as the invoice date, amount, VAT details, and customer/supplier information.
- E-invoicing and e-books: Companies must issue and receive electronic invoices (e-invoices) and maintain electronic books (e-books) for their accounting records. E-invoices need to be transmitted through the myDATA platform or other approved electronic invoicing service providers.
- Reporting: Businesses have to submit summarized transaction data to the myDATA platform regularly. This includes data on revenue, expenses, and VAT. The frequency of reporting depends on the size and nature of the business:
- For large enterprises, reporting is typically done monthly.
- For small and medium-sized enterprises (SMEs), reporting is usually done quarterly.
- Data Retention: Companies are required to retain their digital records for at least six years, in accordance with Greek tax legislation.
- Compliance Deadlines: Businesses must adhere to specific deadlines for submitting their transaction data to myDATA. Deadlines may vary depending on the type of transaction and the size of the business. It is essential for businesses to stay updated on the latest deadlines and regulations to avoid penalties.
By following these steps and adhering to the myDATA requirements, businesses operating in Greece can ensure compliance with the country’s tax regulations, promote transparency, and contribute to a more efficient tax administration system.
