What is DAC7 / the HMRC Digital Platform Reporting Rules?

DAC7 is a ‘new’ reporting requirement introduced by HMRC to increase tax transparency within the digital platform economy. It applies to online or digital platforms—such as holiday-letting agencies—that connect sellers with customers. Under DAC7, these platforms must collect, verify, and report information about the income earned by individuals or businesses who use their services. In the case of holiday rentals, this means that if you rent out your property through a platform or an agent, the income you earn from those bookings will be reported to HMRC each year.

For property owners, the key responsibility is to ensure that their personal, tax, and property details are complete and accurate. This includes providing information such as your full name, address, date of birth, National Insurance or UTR number, and bank account details. HMRC uses this information to match the income reported by the platform with your tax records, helping to ensure that everyone pays the correct amount of tax on their earnings.

For agents and management companies, such as holiday-let platforms, DAC7 introduces a legal obligation to collect and report this data on behalf of the property owners. We must verify each owner’s identity, record all payments made during the year, and submit an annual report to HMRC by 31 January covering the previous tax year. Each owner will also receive a copy of the data submitted so they can check it and include it in their own tax return if required.

It’s important that owners respond promptly when their agent requests information, as incomplete or inaccurate details may cause reporting delays or penalties. If details are not updated ahead of the reporting deadline, the platform may be unable to submit the report correctly, and this could result in withheld payments or HMRC enforcement action. DAC7 doesn’t introduce a new tax—it simply ensures that income earned through digital platforms is reported accurately—but compliance is mandatory for both agents and property owners.

  • “DAC7” refers to an EU directive (Directive on Administrative Cooperation, amendment 7) that extends reporting obligations for digital-platform operators. 

  • The UK has introduced its own implementation of these rules (sometimes referred to as “digital platform reporting” or “reporting rules for digital platforms”). 

  • The purpose: to increase tax transparency in the “platform economy,” ensuring that income earned via digital platforms, including rental income from holiday lets, is properly reported to HMRC. 

In short: platforms that connect property owners (or other service providers) with paying customers must collect and report certain data about those sellers to tax authorities.

Why this matters for you, as a property owner

Because we operate a platform (i.e. we take bookings, process payments, act as the intermediary) you are (in many cases) a “seller” under these rules. That means:

  1. We (as the platform/agent) will have to collect certain information from you so we can report it to HMRC.

  2. You will receive a copy of the reported data (so that you can use it in your own tax return, check for errors, etc.). 

  3. If your details are incomplete, inaccurate or out of date, our report may be rejected or penalised, and you may bear consequences.

  4. If you fail to provide required information, you might lose payments, have bookings withheld, or be flagged as non-compliant.

These rules do not themselves impose new taxes — they operate as a reporting and transparency mechanism. But failing to comply may expose you to enforcement risk or penalties associated with HMRC audits/regimes.

What information will need to be collected / reported

The platform (us) must collect and verify “due diligence” information about sellers (i.e. property owners) and their activity. 

Typical data includes:

Type of information

Examples / specifics

Identity / personal details

Full name, date of birth (for individuals), address

Tax identification

Taxpayer identification number (e.g. UTR, national tax ID)

Business or entity details

If you are operating as a company or other legal entity: registration number, business name, address

Banking / payment details

Bank account (sort code, account number, IBAN) or other payment routing details

Transaction data

Amounts paid to you via our platform, number of bookings, commissions/fees deducted, net amounts

Property identifiers

Address or location of the property, type of property, possibly registration/land registry identifiers

We will also have to verify much of this information (e.g. checking that tax IDs are valid, cross-checking addresses). That’s part of the “due diligence” obligations. 

We may request further supporting documents (e.g. proof of identity, proof of address) if necessary.

Timeline & deadlines

  • The UK rules came into force on 1 January 2024. 

  • The first UK reporting to HMRC (covering the calendar year 2024) is due by 31 January 2025. 

  • In future years, you (and we) will need to repeat this annually (i.e. report by 31 January following each year). 

  • We (the platform / agent) will issue forms or requests to you in sufficient time before the reporting deadline so you can supply and confirm your details.

Because this is a new compliance regime, it’s very important to act early to avoid last-minute scrambles or problems.

Our role (as your agent / platform) and what you must do

As your agent, we will:

  1. Issue you a form or interface (electronically or via portal) to collect your seller/owner data (identity, tax details, bank details, etc.).

  2. Request supporting documentation (proofs) when needed.

  3. Verify (to the extent required) your information under “due diligence” rules.

  4. Compile all owner and transaction data into the required report format (XML, as mandated by HMRC). 

  5. File (submit) the report to HMRC by the deadline. 

  6. Provide you with a copy of the submitted data (as required by the rules) so you can check and use it in your recordkeeping and tax return. 

Your responsibilities include:

  • Responding to our requests for data promptly.

  • Providing full, accurate and up-to-date information (and informing us if anything changes).

  • Cooperating if we request documentation to verify your data.

  • Reviewing the copy of your reported data and notifying us if you believe there is an error.

  • Retaining your own records (backups, receipts, and supporting evidence) for audit or inquiry purposes.

If you fail to comply, delays or rejections may result — and those may be harder to fix after the deadline.

Consequences of missing the deadline or supplying incorrect / incomplete data

While the UK rules follow reporting rather than immediate taxation, there are risks in non-compliance:

  • Penalties or fines: HMRC may impose penalties on a reporting platform (us) for late or incorrect reports. Some of that risk may cascade to the underlying owners if data is faulty. According to guidance, failure to submit a report can carry an initial penalty up to £5,000 and daily penalties of up to £600 for ongoing non-compliance. 

  • Rejection of report / need to resubmit: If your data is incomplete or fails HMRC schema or validity checks, the report may be rejected; we may need to redo parts of it. 

  • Delayed payments / account restrictions: In some jurisdictions or under platform policies, platforms may withhold payments or suspend access if a seller fails to provide required data. (While the UK law’s precise mechanism is not identical to all EU DAC7 practices, it’s prudent to expect similar pressure.) 

  • Audit risk: Incorrect or missing reporting may attract greater scrutiny by HMRC, which could lead to further inquiries into your overall tax position (not just rental income).

  • Reputational or operational disruption: missing deadlines or being flagged as non-compliant can disrupt bookings, damage owner trust, or complicate relationships with the platform.

Because the first reporting cycle is “new,” HMRC may be somewhat more flexible, but that is no guarantee. It’s safer to treat compliance as essential from the start.

Tips & best practices (to reduce friction)

  • Provide your details as early as possible — don’t wait until the last month.

  • Double-check your tax identification, address, dates etc. Errors in format or mismatched IDs are a common cause of rejection.

  • Keep proof documents (ID, address, bank statements) ready in case verification is needed.

  • Inform us immediately of any changes (e.g. address change, change in tax status).

  • Review the copy of your reported data after we send it back to you — compare against your records.

  • Maintain your own records (invoices, statements, bank records) for at least several years in case of audit.

  • Be proactive: if anything looks off or ambiguous, ask for clarification — errors are much harder to fix post-submission than pre-submission.

So in essence DAC7 is a UK directive by HMRC to enhance tax transparency in the digital economy, requiring platforms to report seller income to prevent tax evasion. Failure to do so can lead to large fines.
