ENFIA explained for foreign property owners — Greek property tax, made simple.

Every year around early September, an email arrives in the inboxes of roughly six million people. It's from the Greek tax authority (AADE), and it tells them their ENFIA assessment for the current year is ready. The bill that follows can be paid in ten monthly installments running September through June. For most owners it's a small annual irritation. For absentee and diaspora owners, it's also a small annual confusion — because most never quite understood what ENFIA actually is, who calculates it, and what their actual obligations are.

This article explains all of that without legal jargon, with specific numbers, and with the diaspora-owner situation in mind.

What ENFIA actually is

ENFIA — Ενιαίος Φόρος Ιδιοκτησίας Ακινήτων, the Unified Tax on Immovable Property — is the annual Greek property tax. It replaced the older ETAK tax in 2014, was substantially reformed in 2022, and has been revised in smaller ways most years since. For the current 2026 assessment, the framework has two components:

• Main tax (κύριος φόρος ΕΝΦΙΑ). A per-property tax calculated from the property's physical and locational characteristics. Every property in Greece pays main ENFIA, regardless of who owns it.
• Supplementary tax (συμπληρωματικός φόρος ΕΝΦΙΑ). A progressive levy applied to individuals (not properties) whose combined Greek property holdings exceed a legal threshold. The threshold has moved over time and currently sits in the €400,000–€500,000 combined-value range for individuals, with higher thresholds for couples and reductions for certain property types.

The two are billed together. You receive one assessment that bundles both, calculated against your full property profile in Greece.

How the main tax is calculated

The main tax for a single property is a multiplication problem with five inputs:

1. Surface area in square metres (from your E9 declaration — more on this below).
2. Base rate, set by the tax authority for the property's location. Base rates range roughly from €2/m² in low-value rural zones to €13/m² in core central Athens zones. The Greek tax map updates the base rate periodically.
3. Age coefficient. Older properties get a discount, newer properties a small premium. The reference point is the year of construction, with the discount maxing out at properties over 26 years old.
4. Floor coefficient. Top-floor and ground-floor apartments are taxed at different rates than middle floors.
5. Use coefficient. Residential use is the baseline. Commercial and tourist use get different treatment.

The simplified formula: main tax = surface × base rate × age × floor × use × any special-feature adjustments.

A concrete example. A 95 m² 1980s-built second-floor apartment in Pagrati (central Athens). Base rate roughly €4.50/m², age coefficient roughly 0.85, floor coefficient roughly 1.00, use coefficient 1.00. Main ENFIA: 95 × 4.50 × 0.85 × 1.00 × 1.00 ≈ €363 per year. Add the supplementary tax if the owner's total Greek property exceeds the threshold (in this case, it usually doesn't for a single mid-market apartment), and the total annual ENFIA for this property is in the €350–€450 range.

That's the broad shape of it. The actual calculation has more nuance — adjustments for waterfront properties, properties at altitude, properties with special architectural features, properties in protected zones — but the structure above accounts for the vast majority of bills.

The E9 declaration, and why it matters more than the ENFIA bill

ENFIA is computed automatically from your E9 declaration — the personal property registry filing that every Greek property owner maintains with AADE. The E9 lists every property you own in Greece, its physical characteristics (size, age, floor, use), and your ownership share (100% if sole owner, 50% if joint, etc.).

If your E9 is wrong, your ENFIA is wrong. And the most common diaspora property situation produces wrong E9s, often for years before anyone notices.

The wrong-E9 problem usually looks like one of these:

• Inherited property still in the deceased person's name. The Greek tax authority continues to bill the deceased's E9 record, penalties accrue, and the heirs receive no notification because the correspondence goes to the deceased's old address.
• Renovations or extensions not declared. An apartment that was 75 m² when it was purchased is now 90 m² after the balcony was enclosed in 2008. The E9 still shows 75 m². ENFIA is correspondingly low. When this is eventually discovered (often when the property is sold), back-taxes and penalties apply.
• Joint ownership confusion. A property that belongs 60% to one sibling and 40% to another is filed incorrectly as 50/50 because the heirs guessed at percentages without consulting the will. Both siblings get incorrect ENFIA bills.
• Outdated address for correspondence. The Greek tax authority sends notifications to the contact address listed in your tax file (φάκελος). For owners abroad, this is often a relative's old Athens address, a house that's been sold, or a Greek post box that nobody checks. Important notices go missing.

How non-residents pay ENFIA

The mechanical answer: through your Greek tax representative (φορολογικός εκπρόσωπος / αντίκλητος). Every non-resident Greek property owner is legally required to nominate a Greek tax representative — usually a Greek accountant or lawyer — who is registered with AADE and handles correspondence and filings on your behalf.

The representative does not pay your ENFIA. You pay it. What the representative does is receive the assessment, verify it against your E9, alert you to any inaccuracies before payment, file any disputes, and coordinate with you to pay through the AADE digital platform (taxisnet). Payment is typically made by Greek bank transfer, IRIS instant payment (between Greek bank accounts), or direct debit from a Greek euro account.

If you don't have a Greek bank account, your accountant can usually arrange payment from a Greek client account on your behalf and bill you separately — this adds a small handling fee but works perfectly well for diaspora owners who don't maintain Greek banking infrastructure.

2026 status: smaller, more progressive, more digital

The 2022 ENFIA reform delivered an average reduction of around 13% for individual owners, with larger reductions for primary residences and properties in lower-value zones. Subsequent annual updates have continued the trend — small reductions, tighter thresholds, more digitalisation of the filing process. The 2026 framework keeps the structure intact, with marginally lower base rates in some island zones and slightly higher thresholds for the supplementary tax.

Most diaspora owners with a single mid-market Greek property pay ENFIA in the €200–€700 annual range. Properties in core central Athens or premium Riviera zones can reach €1,500–€4,000 per year. Multi-property portfolios that trigger the supplementary tax can add several thousand more, depending on combined value.

Common mistakes — and what they cost

• Not appointing a Greek tax representative. Cost: missed assessments, accumulated penalties, eventual blocked sale of the property. Severity: high.
• Ignoring the E9 after inheritance. Cost: incorrect bills for years, eventual back-tax assessment, complications when title transfer is finally attempted. Severity: very high.
• Not declaring renovations. Cost: back-tax + penalties when discovered, especially at point of sale. Severity: medium to high.
• Paying late. Cost: small monthly interest charges, eventually escalating to enforcement actions. Severity: low if caught quickly, medium if ignored.
• Trusting that your relative's accountant is handling it. Cost: variable — sometimes everything is fine, sometimes nothing has been filed in three years. Severity: depends entirely on the relative and the accountant.

What good ENFIA management looks like for an absentee owner

Four practices that reduce the risk to near-zero:

1. A dedicated Greek tax representative who is your representative — not your aunt's, not the family accountant from 1992. Someone who has your contact details and will email you when the assessment arrives, not phone the old number that doesn't ring anymore.
2. An annual E9 review. Once a year — typically in spring before the assessment is generated — have your representative confirm your E9 matches reality. Five minutes of attention, saves years of trouble.
3. A clean documentation folder. Title deeds, purchase contracts, renovation paperwork, inheritance documents — all digitised and accessible. The minute a discrepancy comes up, you can resolve it without flying to Athens.
4. A point of contact who can attend to the property itself. Because ENFIA assessments sometimes flag things that need physical verification — was the balcony enclosed? Is the property actually a primary residence as declared? — having somebody local who can confirm matters in person makes the difference between a quick clarification and an open audit.

Quick-reference summary

• ENFIA is the annual Greek property tax. Two parts: main (per property) and supplementary (per individual, above threshold).
• Calculated from the E9 declaration, not from a separate filing.
• Non-residents pay through a Greek tax representative on the AADE digital platform.
• Most diaspora owners pay €200–€700 per year per single property; premium-zone properties pay more.
• The biggest risk for diaspora owners is an out-of-date E9 — typically after inheritance, renovation, or change of ownership share.
• Annual E9 review with your tax representative is the single most valuable defensive practice.
