DAC7 and Platform Reporting: How Airbnb and Booking.com Tell Tax Authorities About Your Rental Income

Published on: August 19, 2026

Quick answer: If you let a property abroad through a booking platform, the tax authority in that country almost certainly already has your name, your tax number, the property address, the number of days it was let and the gross amount the platform paid you. DAC7 obliges platforms to report it and authorities to exchange it. The widely quoted exclusion for small sellers, 30 transactions and 2,000 euros, applies to sellers of goods and not to property rental, so a single week let is reportable. The regime creates no new tax; it removes the assumption that a foreign holiday flat is invisible.

If you own a property abroad and let it through a booking platform, a tax authority in that country almost certainly already knows your name, your address, your tax identification number and exactly how much gross rent the platform paid you last year. It did not find this out through an investigation. The platform sent it, automatically, because the law requires it to.

This is the practical effect of DAC7 in the European Union and of a set of near identical rules now operating in the United Kingdom and a growing list of other countries. For owners who declare their rental income properly, it changes very little. For owners who assumed that a holiday flat in another country was invisible to the tax office, it has changed everything, and 2026 is the year the resulting letters started arriving in volume.

What DAC7 actually is

DAC7 is the common name for Council Directive (EU) 2021/514, the seventh amendment to the EU's directive on administrative cooperation in tax matters. It obliges digital platform operators to collect, verify and report information about the sellers who earn money through them.

Four categories of activity are in scope: the rental of immovable property (residential and commercial), personal services, the sale of goods, and the rental of any mode of transport. Short-term and long-term property rental both fall inside the first category.

The obligation sits on the platform, not on you. But the platform cannot meet it without your data, which is why hosts have spent the last two years being asked to confirm a tax identification number, a date of birth and a registered address before payouts continue.

Two features matter most to property owners.

It reaches beyond the EU's borders. A platform established outside the EU is still caught if it facilitates the rental of property located in the EU or has EU-resident sellers. A US or Asian booking platform listing a Spanish apartment is inside the regime.

Reported data is exchanged between countries. The platform reports to one member state; that state passes the information to the state where you are tax resident and to the state where the property sits. A German resident letting a house in Portugal generates a data trail visible to both authorities.

The threshold that does not apply to you

A great deal of confusion comes from a widely quoted exclusion: sellers with fewer than 30 transactions and no more than 2,000 euros in annual consideration do not have to be reported.

That exclusion applies only to sellers of goods. There is no equivalent floor for property rental. A landlord with two bookings in the year is reportable. A single week let in August is reportable.

There is a separate exclusion at the opposite end of the scale for very large accommodation providers, broadly those with more than 2,000 rentals in respect of a single property listing during the year, which is aimed at hotel groups rather than individual owners.

If you have read on a platform's help page that you are below the DAC7 threshold, check whether that page was written for its goods marketplace. For a rental listing, assume you are reportable.

What the platform actually sends

The reported package is more detailed than most owners expect. For an individual host it typically includes:

That last row is the one that catches people out. The report is not a single income figure. It is property-level, with days rented attached. A tax authority can compare the number of nights a unit was let against a local registration scheme, a tourist tax return and a personal declaration, and see three different numbers.

The figure reported is gross. It is the amount paid or credited to you before the platform's commission in most presentations, and certainly before your mortgage interest, cleaning costs, management fees and local taxes. Your taxable profit will normally be much lower. A letter quoting a large gross figure is not an assessment.

The timeline, and why letters are landing now

The lag is the point. Authorities spent the first cycles building the matching infrastructure, and only then started running platform data against filed returns. Germany, for example, began sending a large wave of letters to platform sellers during 2026 on the basis of data filed in the January 2026 cycle. Other administrations are on similar trajectories.

Deadlines vary slightly at national level. Platforms generally complete their due diligence on sellers by 31 December and file by 31 January, though Germany's domestic statute sets its own filing date, and penalties for late or incorrect filing are set individually by each member state and can be severe.

Outside the EU: the same rules under a different name

DAC7 is the EU's implementation of a global standard, the OECD Model Reporting Rules for Digital Platforms. Several countries have adopted the model directly or run something functionally equivalent:

• United Kingdom. The Platform Operators (Due Diligence and Reporting Requirements) Regulations 2023 took effect on 1 January 2024, with the first reports covering 2024 filed by 31 January 2025. Airbnb, Booking.com and Vrbo report host identity and income to HMRC. Note that the UK reporting threshold is not the same thing as the UK tax threshold: you may be reported and still owe nothing, for example under the property allowance or rent-a-room relief.
• Australia. The Sharing Economy Reporting Regime has required short-term accommodation platforms to report transactions to the Australian Taxation Office since 1 July 2023, with other platform categories phased in afterwards.
• Canada, New Zealand, Norway and a widening group of others have adopted the OECD model rules or their own equivalents.

The list keeps growing, so treat any snapshot as a starting point rather than a final answer. The direction of travel is uniform: platform income is becoming one of the most transparent categories of income anywhere.

DAC7 also sits alongside, and is separate from, the Common Reporting Standard, which exchanges bank account information. If you receive rent into a foreign account and also let through a platform, two separate reporting channels are describing the same activity. See our guide to CRS and the foreign property owner for how the two interact.

Why non-resident owners get caught more often than residents

Nothing in DAC7 targets foreigners. The pattern is a by-product of five ordinary mistakes that non-resident owners make more often than locals.

Assuming the platform's tax handling is your tax handling. Platforms collect and remit local tourist or occupancy taxes in many cities, and some withhold amounts in specific jurisdictions. None of that is your income tax return. Two obligations, two processes.

Filing in the wrong country only. Rental income from immovable property is, under most double tax treaties, taxable first in the country where the property sits. Declaring it at home and nowhere else is one of the most common errors. Relief for double taxation is normally given by the country of residence after the source country has taxed it, not instead of it. Our non-resident rental income tax guide sets out how this works country by country.

Assuming a loss means no filing obligation. In many countries a non-resident landlord must file even where the result is nil or negative. No profit does not mean no return.

Missing the registration layer. A tourist licence or registration number is a separate requirement from tax, and the platform's report often contains the property address and days rented that lets an authority check it. Our guide to holiday let licensing covers the current regimes.

Confusing gross with net. Owners see a large reported figure and panic. What has been reported is turnover, not profit.

If the numbers do not match

A letter or a mismatch is not an accusation, and the reported figure is not always right. Platforms have misallocated income between co-owners, reported in the wrong currency, attributed a property to a former owner after a sale, or double counted where a listing was managed through an intermediary.

Reasonable first steps, none of which are a substitute for professional advice:

1. Download the platform's own annual earnings summary for each year in question. Every major platform provides one, including for closed accounts.
2. Reconcile it against what you declared, line by line, in both the source country and your country of residence.
3. Separate gross from net, and identify commissions, cleaning fees, and any taxes the platform withheld or remitted on your behalf.
4. Check which entity or person the platform holds as the recipient, particularly with co-owned property or a management company in the chain.
5. Respond within the deadline stated in the letter, even if only to ask for time.

Where a genuine under-declaration has occurred, most tax administrations operate a voluntary disclosure route, and the treatment is typically more favourable when the taxpayer comes forward before being prompted. The rules, time limits and penalty ranges differ substantially by country, so this is the point to involve a tax adviser qualified in the relevant jurisdiction rather than to act on general guidance.

Frequently asked questions

Does DAC7 create a new tax on rental income?
No. It is a transparency measure. It changes what the authorities can see, not what you owe. Obligations that already existed simply become much harder to overlook.

I only rented my apartment for one week last year. Am I reported?
Almost certainly yes. The 30 transaction and 2,000 euro exclusion applies to sellers of goods, not to property rental.

I deleted my listing. Does that remove me from the report?
No. Reporting covers the calendar year in which the activity occurred. Closing an account afterwards does not withdraw the filing.

I rent through a local property manager, not directly on the platform. Am I outside the regime?
Not necessarily. Where the manager operates on a platform, the report may name the manager, you, or both, depending on who the platform recognises as the seller and how payouts flow. This is worth clarifying with the manager in writing.

Does this apply to long-term residential tenants found through a portal?
The category is rental of immovable property generally, not only short stays. Whether a particular portal is a reporting platform depends on whether it facilitates the transaction or merely advertises. Pure classified advertising, payment processing alone and simple redirection are outside the definition.

Which countries receive the data?
Broadly, the country where you are tax resident and the country where the property is located, through automatic exchange between authorities.
