Property owners across Greece have until January 31 to revise their E9 declarations, giving them a final opportunity to reduce or even eliminate their ENFIA property tax. Many households stand to benefit significantly by correcting longstanding errors in their forms. Updated information submitted before the deadline will be reflected in ENFIA clearance notes expected toward the end of February, with the first payment due at the end of March.
Thousands of owners are now reviewing their E9 entries after identifying omissions or inaccuracies that inflated previous tax assessments. Adjusting these details ensures that the tax calculation accurately reflects the characteristics of each property.
Common E9 Errors
Incorrect declarations frequently lead to higher ENFIA charges. Auxiliary spaces are often mistakenly listed as main areas, causing the tax office to disregard the 90 percent discount normally applied to these secondary structures.
Basements are regularly recorded as primary-use spaces, which results in an unnecessarily elevated tax burden. Many owners also provide inaccurate square meter figures for both main and auxiliary areas, creating discrepancies that increase their liability.
Missing floor numbers appear often in E9 forms, and this omission forces the system to apply the coefficient for the 6th floor, which is typically the highest. Buildings that are empty, unfinished, non electrified, or electrified with construction power are also frequently left undeclared, which eliminates a potential 60 percent reduction.
Professional storage units located on agricultural plots are sometimes misclassified, prompting the system to treat them as houses and multiply the tax fivefold. Another recurring issue occurs when the completion year of a structure is declared instead of the building permit year, a detail that prevents owners from benefiting from older age discounts.
Property rights such as full ownership, bare ownership, or usufruct are occasionally missing or incorrectly stated, resulting in unfair charges. Ownership percentages are also left blank in some cases, automatically triggering an assessment based on 100 percent ownership. Mezzanine levels connected by internal staircases are frequently declared together with main spaces, which can also distort the tax calculation.
