UK-Greece Double Tax Treaty for STR Rental Income 2026 (Post-Brexit)

UK-Greece Double Tax Treaty for STR Rental Income 2026 (Post-Brexit)

You own a Crete villa, an Athens apartment or a Kefalonia townhouse and you list it on Airbnb. As a UK tax resident you owe tax in two places: in Greece because the property sits there, and in the UK because HMRC taxes worldwide income on the arising basis. The 1953 UK-Greece Convention for the Avoidance of Double Taxation, signed in Athens on 25 June 1953 and never replaced, prevents the double burden through the foreign tax credit method. This guide walks through art. 6 immovable property, art. 18 elimination of double taxation, the post-Brexit non-EU classification, HMRC SA106 and the Greek E1 plus E2 reconciliation that any UK owner of Greek STR must master.

The Convention between the United Kingdom and the Hellenic Republic for the Avoidance of Double Taxation, signed in 1953, is the oldest UK bilateral tax treaty still in active use. Despite its age, it remains valid: both countries have repeatedly confirmed its standing through the OECD Multilateral Instrument (MLI) protocols of 2017 and the post-Brexit administrative letters of 2021. The treaty was never modernised because both jurisdictions found the original text adequate. The MLI added a principal purpose test plus tighter exchange of information but the substantive distribution rules (which country taxes what) remain as drafted in 1953.

Article 6: Where Greek Vacation Rental Income Is First Taxed

Article 6 of the 1953 UK-Greece Convention covers income from immovable property. The text follows the pre-OECD wording of the era: income derived by a resident of one of the territories from immovable property situated in the other territory shall be subject to tax in accordance with the laws of that other territory. In plain modern English: Greece has the primary right to tax Greek vacation rental income, regardless of where the owner lives.

The article covers all forms of immovable property income: long-term rentals, short-term holiday lets, agricultural revenue, mineral and quarry rights. Income from a Mykonos villa, an Athens apartment or a Heraklion townhouse falls under art. 6. The fact that the booking is processed by Airbnb Ireland Unlimited Company, paid through Stripe and credited to a UK Halifax account does not change the source: the property is in Greece, the income is Greek-source, primary taxing right belongs to Greece.

How Greece Taxes Non-Resident UK Rental Income

A UK tax resident is treated as a non-resident in Greece for Greek income tax purposes. The relevant statute is ΚΦΕ (Κώδικας Φορολογίας Εισοδήματος, Νόμος 4172/2013) plus the STR-specific overlay of Νόμος 5170/2025. STR rental income earned by a non-resident UK owner is taxed in Greece at the progressive rental income scale (15% on the first 12,000 EUR, 25% on the 12,001 to 24,000 EUR band introduced in 2026, 35% on the 24,001 to 35,000 EUR band, 45% above).

The Greek tax regime is broadly similar for residents and non-residents on rental income, with one key difference: non-residents cannot offset Greek rental income against Greek personal allowances or family deductions because they have no Greek residence. The flat tax rates apply from the first euro. A UK owner with 30,000 EUR of Greek STR gross income and no deductible expenses pays approximately: 12,000 at 15% (1,800) plus 12,000 at 25% (3,000) plus 6,000 at 35% (2,100) equals 6,900 EUR Greek income tax. Add ΕΝΦΙΑ annual property tax, Climate Resilience Fee passed through (not a host expense) and the supplementary tax above the 3rd property threshold, and the gross-to-net conversion for foreign owners in Greece is among the more complex in the EU.

How the UK Taxes the Same Income

HMRC taxes UK residents on worldwide income on the arising basis (the remittance basis was abolished from 6 April 2025 by the Finance Act 2025, replaced by the Foreign Income and Gains regime that exempts certain new arrivals for 4 years but does not help long-term residents). A UK resident landlord with a Greek vacation rental declares the income on SA106 (foreign income pages) of the Self Assessment return.

The Furnished Holiday Letting (FHL) regime that previously applied to qualifying overseas holiday lets was abolished on 6 April 2025 by the Finance Act 2025. From tax year 2025-26 onwards all overseas property is reported as ordinary foreign property on SA106, with standard expense rules. Mortgage interest relief on overseas property is restricted to a 20% basic-rate tax credit, mirroring the UK domestic property regime under Section 24 Finance (No.2) Act 2015.

UK income tax bands for 2025-26: personal allowance GBP 12,570 (tapered to nil above GBP 125,140), basic rate 20% up to GBP 50,270, higher rate 40% up to GBP 125,140, additional rate 45% above. Scotland operates separate bands and rates.

Article 18: Elimination of Double Taxation Through the Credit Method

Without relief, a UK higher-rate owner with Greek vacation rental income would face Greek progressive rates plus 40% UK on the same euro: an effective 70%-plus combined burden. Article 18 of the 1953 Convention solves this through the credit method. Greece is the source state and gives no credit to UK residents. The UK is the residence state and gives credit against UK tax for the Greek tax paid on the same income, capped at the UK tax that would otherwise be due on that income.

Practical sequence:

1. Compute Greek tax through the E1 (annual personal income return) and E2 (rental income annex) by 30 June following the tax year. Pay in 8 monthly instalments via myAADE SEPA debit through August to March.
2. Convert the Greek tax paid into GBP at the HMRC monthly average rate (or spot rate at payment date).
3. Declare the gross Greek income on SA106 in GBP at a consistent conversion convention.
4. Claim allowable UK expenses against the gross income (cleaning, agency fees, ΕΝΦΙΑ, repairs, insurance, mortgage interest as a 20% credit). The UK lets you deduct items that Greece does not.
5. Enter the Greek tax paid in box 2 of SA106 (Foreign tax taken off or paid). HMRC offsets the foreign tax credit against the UK tax computed on the Greek-source income, capped at that UK tax.

Worked Example: Crete Villa, UK Higher-Rate Owner

Numbers for tax year 2026 (Greek E1 plus E2 for calendar year 2025 filed by 30 June 2026, UK Self Assessment for 2025-26 due 31 January 2027):

Line	EUR	GBP (at 1.18)	Notes
Gross rental income	30,000	25,424	120 nights at 250 EUR average
Greek progressive tax (15-25-35%)	6,900	5,847	Greek rental income scale
UK gross income (full 30k)	30,000	25,424	SA106 foreign property pages
UK allowable expenses (itemised)	9,500	8,051	Cleaning, agency, ΕΝΦΙΑ, insurance
UK net foreign property profit	20,500	17,373	Carried to SA106 summary
UK tax at 40% (higher rate)	n/a	6,949	Before foreign tax credit
Foreign tax credit (capped at UK tax)	n/a	5,847	Greek tax in GBP
UK tax after credit	n/a	1,102	Net UK liability
Combined burden (Greece plus UK)	n/a	6,949	Effective 27% on gross GBP income

Two points worth noting. First, the Greek progressive scale on gross is high enough that for most UK higher-rate owners it covers most of the UK tax liability. The foreign tax credit caps out at the UK tax on the same income, so any Greek tax above that cap is lost. Second, the 1953 treaty is symmetric in its credit rules but asymmetric in the tax rates the two countries apply, so combined burden often exceeds either country's headline rate by 5 to 10 percentage points compared to a UK-only or Greece-only scenario.

E1 plus E2 Annual Reconciliation

The Greek annual cycle for STR rental income runs as follows. E1 (Δήλωση Φορολογίας Εισοδήματος Φυσικών Προσώπων, the personal income return) is filed by 30 June following the tax year. E2 (Αναλυτική Κατάσταση Μισθωμάτων Ακινήτων, the rental property annex) is filed alongside, listing each property, each tenant or platform and gross income received. Climate Fee monthly returns are separate (filed by the 20th of each following month). ΕΝΦΙΑ is computed annually by ΑΑΔΕ from your E9 cadastral declaration and paid in 8 instalments August to March.

The reconciliation HMRC sometimes asks for is between the Airbnb dashboard, the Greek E2 annual rental schedule and the SA106 annual figure. Discrepancies above 5% trigger an HMRC enquiry. Keep for at least 6 years: Airbnb yearly earnings summary, the E2 annex with line-by-line property income, the E1 acknowledgement, ΕΝΦΙΑ annual statement, Climate Fee monthly receipts and a GBP conversion log line by line.

Frequently Asked Questions

Do I need to file in both countries every year?

Yes. Greek E1 plus E2 by 30 June (filed jointly through myAADE), Climate Fee monthly through the year, plus UK Self Assessment SA106 by 31 January (online) or 31 October (paper). Missing either deadline triggers separate penalties: from 100 EUR in Greece under art. 54 ΚΦΔ, GBP 100 plus daily charges in the UK under FA 2009 Sch. 55.

Can I deduct Greek expenses on the UK return even though Greece does not let me?

Yes. The UK and Greek expense regimes are independent. UK SA106 follows UK rules: cleaning, agency commission, ΕΝΦΙΑ, repairs, insurance, mortgage interest (as a 20% credit only), management fees and marketing are all deductible under HMRC rules even where the Greek scale gives no equivalent allowance. Document the expenses with invoices in case of an HMRC enquiry.

Does the treaty cover capital gains on selling the Greek property?

Yes. Article 8 of the 1953 Convention covers gains from alienation of immovable property. Gains from the sale of a Greek property are taxable in Greece (15% flat under the special STR regime if the property was let on a registered ΑΜΑ, on the net gain after acquisition cost, transfer taxes paid on purchase, improvements and depreciation already deducted). Greek law exempts capital gains on personal properties held over 5 years for residents but not consistently for non-residents. The UK then gives a foreign tax credit under art. 18 against UK CGT (24% residential property rate from 30 October 2024 Budget for higher-rate taxpayers).

Can I rely on EU-resident treatment if I keep dual UK and Irish citizenship?

Citizenship is irrelevant for Greek tax classification. What matters is tax residency. If you are tax resident in Ireland (an EU member state) you qualify as EU for any Greek STR tax overlays that distinguish EU from non-EU. If you are tax resident in the UK, even with an Irish passport, you are non-EU for Greek tax purposes. Tax residency follows the OECD test in art. 4 of the relevant treaty: permanent home, centre of vital interests, habitual abode, nationality.

What if the platform already remits Climate Fee?

Airbnb does not remit Greek Climate Fee. The host collects from the guest and remits monthly to ΑΑΔΕ. Airbnb does report your gross receipts to ΑΑΔΕ under DAC7 (Νόμος 5045/2023 transposes DAC7 in Greece) via the platform feed. The withholding obligation remains on the host through the E2 plus Climate Fee monthly cycle. UK PAYE does not apply to foreign rental income, so you self-assess UK tax through Self Assessment.

Need help reconciling the Airbnb dashboard with the Greek E2 plus monthly Climate Fee filings and the annual UK SA106, computing the foreign tax credit cleanly and tracking the post-Brexit non-EU classification? The Standard Package HostReady (Greece) includes an E1 plus E2 annual calendar, a Greek progressive scale walkthrough for UK owners, an SA106 expense itemisation template and a GBP-EUR conversion log designed for owners filing in both jurisdictions.
