Greek residents are liable to income tax on their worldwide income, whether remitted to Greece or not. Where tax has already been paid outside Greece on non Greek-source income, it may be deducted up to the amount of tax payable in Greece on the same income. Non-Greek residents are taxed only on Greek-source income.
The legal provisions designed to prevent tax evasion specify that individuals filing a tax return in Greece are taxed on the higher of their declared income or imputed income. Income is imputed on the basis of living expenditure or acquisition of certain assets. The main factors considered in imputing income from living expenses or acquisitions are:
- the engine size of owned motor vehicles
- the repayment of loans
- the purchase of real estate
- the construction, acquisition, or leasing of buildings
- acquisition or leasing of other assets, such as motor cars or pleasure boats
- the deemed rental payments for a secondary residence or more than one secondary residencies, as well as a primary residence (by reference to the residence's surface)
- the construction, maintenance, and use of a swimming pool (outdoor/indoor by reference to the pool’s surface)
- amounts donated to non–state institutions or to individuals including monetary parental donations
- other factors, such as the annual expense of the tuition fees or housekeeping staff.
Under certain circumstances, taxpayers have the right to contest the imputed income assessed on the basis of their lifestyle by providing evidence that the difference between the imputed income and the declared income is covered by borrowing or savings that have been taxed or exempted from tax in the past from gifts, which have been subject to or exempt from gift tax, income taxed abroad (or exempted), and imported to Greece, and so on.
Although married persons are taxed separately on their own income they are required to file a joint tax return.
The official currency of Greece is the Euro (EUR).
