Greek Objective Property Tax Value System: ENFIA, TAP, and E9

The Greek objective property tax value, known in Greek as Antikeimenikes Axies, is a government-assigned valuation that sets the minimum tax base for nearly every levy tied to real estate in Greece. It is built from a neighborhood zone price and adjusted by coefficients for the property’s physical traits, not from what a buyer would pay on the open market. Whether you own an Athens apartment, inherit a family home on an island, or plan to buy, this figure drives your annual property tax, transfer tax, inheritance and gift tax, and municipal fees.

How the Objective Value Is Built

The starting point is the zone price, or Timí Zónis, a euros-per-square-meter figure assigned to a specific block. The Ministry of Finance publishes these zone prices on an interactive map run by the Independent Authority for Public Revenue (AADE); you can zoom to a street and read the rate that applies.¹ The system was authorized under Law 1249/1982, which requires periodic updates to keep values in line with economic conditions.

The zone price is then adjusted by coefficients that reflect the individual property. The main ones:

Age (Palaiótita). Older buildings receive a depreciation discount. A 1960s structure carries a substantially lower multiplier than a new build on the same street.
Floor level. Upper-floor apartments carry higher values than ground-floor units.
Frontage (Prosopsi). A unit facing a main road or with multiple street exposures gets a higher coefficient than one behind an interior courtyard.
Use. Commercially designated spaces can trigger higher multipliers because of their income-generating potential.
Façade count. The number of building sides exposed to public roads nudges the value up or down.

This is why two apartments in the same building can carry different objective values. A top-floor corner unit with two street frontages will be valued higher than a same-sized ground-floor interior unit, even though the zone price is identical.²

The zone price alone is not the finished number. Reaching the full objective value requires the property details from the building permit, deed, and a topographic diagram prepared by a licensed civil engineer. Those inputs feed a calculation sheet (Fyllo Ypologismou) that applies the coefficients to the zone price. Errors on that sheet, especially a wrong zone price or misidentified floor, produce incorrect assessments and can stall a transfer.

Objective Value vs. Market Price

Objective values often sit well below market prices, sometimes by a wide margin. In high-demand Athens neighborhoods such as Kolonaki, properties have sold at 60% or more above the zone rate, and the same pattern appears in areas like Glyfada and on the islands. The gap exists because the last broad adjustment happened in June 2021, and the government has frozen values at those levels through at least 2027.

The freeze cuts both ways. Annual tax bills stay predictable, but the tax base falls further behind reality in the hottest markets each year. For buyers, this generally helps at purchase: transfer tax is calculated on the higher of the objective value or the contract price, so where the objective value trails, the contract price controls and you pay tax on what you actually spent. For inheritance and gift purposes, a lower objective value directly reduces the taxable amount.

Taxes That Ride on the Objective Value

ENFIA, the Annual Property Tax

The Unified Property Ownership Tax (ENFIA) has been levied annually since 2014 under Law 4223/2013. It applies to anyone holding property rights in Greece as of January 1 of the tax year, whether resident, EU citizen with a vacation home, or foreign investor.³ The main tax is calculated per property using zone price, area, use, age, floor, and number of façades. A supplementary tax applies only to legal entities, at 5.5 per thousand of the property’s value, or 1 per thousand if the entity uses the property for its own business.²

Transfer Tax

Buyers owe a transfer tax (FMA) of 3% of the taxable value.⁴ The taxable value is the objective value in most cases, but if the contract price is higher, tax is calculated on the contract price.⁵ Underreporting the sale price to reduce tax accomplishes nothing, since the objective value already sets a floor.

Inheritance and Gift Tax

Inheritance and gift taxes also run on the objective value of the transferred property. Parental gifts to children benefit from a tax-free threshold of €800,000 per parent, with any amount above that taxed at a flat 10%. This is not a progressive scale; once you cross the €800,000 line, the entire excess is taxed at the same rate. Inheritance tax for close relatives (Category A beneficiaries, including spouses and children) follows a separate schedule with its own thresholds and brackets, while more distant relatives and unrelated beneficiaries face steeper rates.

Municipal Property Duty (TAP)

On top of ENFIA, every owner pays the Municipal Real Estate Duty (TAP), collected through the electricity bill. The rate runs between 0.025% and 0.035% of the objective value, adjusted by a building-age coefficient. Amounts are modest, but they catch some foreign owners off guard when they first see itemized electricity charges.

The 15% Special Tax on Offshore-Held Property

Legal entities that hold Greek real estate through opaque ownership structures face a special annual tax of 15% on the objective value. This rate, established under Law 3091/2002 and in effect since 2010, targets companies whose ultimate beneficial owners are not disclosed to Greek authorities. Exemptions exist for entities that can demonstrate transparent ownership, including shipping companies operating under Emergency Law 89/1967, organizations pursuing charitable or educational purposes in Greece, and certain foundations. To claim the exemption, the entity files an initial return online by May 20 of the tax year, and the applicable tax is payable as a lump sum within three business days of filing.⁶ If you plan to buy Greek property through a foreign company, this 15% charge is one of the first items to raise with a Greek tax advisor.

Looking Up Your Property’s Objective Value

The Ministry of Finance offers a digital map that returns the current zone price for a given block.⁷ Navigate to the region, find the street, and the system displays the Timí Zónis for the specific block. AADE runs a parallel interactive map with the same zone data overlaid on satellite imagery.¹ To convert the zone price into the finished objective value, the coefficients from the calculation sheet still have to be applied, using the property’s legal description.

The E9 Declaration and the Audit Window

Every property owner in Greece must file an E9 declaration, a full inventory of real estate holdings. The E9 feeds directly into ENFIA and is how the tax authority ties your identity to specific properties and their objective values. Required fields include square footage, property type, co-ownership percentage, geographic location (by address or by reference to the objective value map), and the electricity supply number for any building where you hold full ownership or a usufruct right.⁸

Since 2014, the E9 must also include the notarial contract number, date, and notary identification, plus details of any will affecting the property. The deadline for any new acquisition or change in property rights is May 31 of the following year. Buy a property in October 2026, and you have until May 31, 2027, to update your E9. Late or inaccurate filings trigger a fine assessed alongside ENFIA, though the law waives penalties for amended E9 declarations covering past years while the national cadastre is still being completed across the country.⁸

Greek tax authorities have five years from the end of the year in which a return was due to audit a valuation and issue a corrective assessment. That window can extend by one year if, for example, an amended return is filed in the fifth year or new information surfaces late. If no return was filed at all, or if previously unknown information reveals that the liability exceeds what was originally assessed, the window stretches to ten years. Understating characteristics on an E9 or calculation sheet, such as a lower floor level or omitted auxiliary space, gives the authority a long runway to catch it. Corrective assessments typically come with interest and administrative penalties on top of the back taxes owed.

Challenging the Valuation

Owners are not entirely stuck with the state’s number. The Council of State, Greece’s highest administrative court, has ruled that objective values must bear a reasonable relationship to actual market conditions and that the government was legally obligated to adjust zone prices when the existing values fell out of step with real market prices. The court grounded that obligation in Law 1249/1982.

On an individual level, though, the appeal path is narrow. Zone prices apply to entire blocks, so disputing your property’s objective value typically means arguing that the zone classification is wrong or that a coefficient was applied incorrectly. Coefficient errors, like the wrong age or floor designation on a specific property, can be corrected through an E9 amendment. Convincing the state that the zone price for an entire neighborhood is too high requires a judicial challenge, which is slow, expensive, and realistically worthwhile only when the stakes are very large.

Notes for U.S. Owners

Americans owning Greek property carry a separate layer of U.S. reporting that intersects with the objective value system in specific ways. Greek property held directly in your own name does not go on the FBAR (FinCEN Form 114) or Form 8938. Greek bank accounts used for property expenses do trigger FBAR filing if aggregate foreign account balances exceed $10,000 at any point in the year. Form 8938 has higher thresholds: $50,000 for single filers in the U.S. at year-end (or $75,000 at any point), and $200,000 for single filers living abroad at year-end (or $300,000 at any point).⁹ Property held through a foreign entity flips the analysis: the entity becomes a reportable financial asset on Form 8938, and its value includes the underlying real estate.

Rental income from Greek property must be reported on your U.S. return. The U.S.-Greece tax treaty allows Greek income taxes to be credited against U.S. liability through IRS Form 1116.¹⁰ The foreign tax credit only covers income, war profits, and excess profits taxes. Greek property taxes like ENFIA are not income taxes and generally do not qualify for the credit.¹¹ ENFIA may be deductible as a rental expense where the property produces rental income, which reduces taxable profit rather than offsetting U.S. tax dollar-for-dollar. That distinction changes the numbers more than most owners expect on the first pass.
