When HMRC wants to know who the landlords are behind a class of properties, it does not have to go knocking door to door. Schedule 36 of the Finance Act 2008 gives HMRC a tailored power — paragraph 5A — to compel any business holding identity-traceable records to disclose landlord names, last known addresses and dates of birth.

That power has been the procedural backbone of HMRC's Let Property Campaign since the campaign opened in 2013 — and it is the route by which letting agents, short-let platforms, online marketplaces and conveyancing platforms find themselves on the receiving end of HMRC data requests.

This piece walks the statutory text verbatim, the four-condition test, the procedural carve-outs that protect recipients from over-broad demands, and the appeal route under paragraph 31.

What paragraph 5A actually says

Paragraph 5A was inserted into Schedule 36 by section 224(2) Finance Act 2012, with retrospective effect — section 224(7) makes the new power available for the purpose of checking the tax position of a taxpayer as regards periods or tax liabilities "whenever arising (whether before, on or after the day on which this Act is passed)".

Sub-paragraph (1) reads in full:

An authorised officer of Revenue and Customs may by notice in writing require a person to provide relevant information about another person ("the taxpayer") if conditions A to D are met.

Conditions A to D narrow the power. Each must be satisfied independently.

Condition A: information reasonably required

Sub-paragraph (2), as amended by section 127 Finance Act 2021:

Condition A is that the information is reasonably required by the officer for the purpose of checking the tax position of the taxpayer or for the purpose of collecting a tax debt of the taxpayer.

The "tax debt" limb was inserted by section 127 FA 2021, expressly extending Schedule 36 beyond compliance-checking into tax-debt collection — and applying retrospectively to liabilities "whenever arising". The wider Finance Act 2021 section 127 extension is examined in our earlier piece on Finance Act 2021 section 127's extension of HMRC's Schedule 36 reach.

"Reasonably required" carries the same objective threshold here as elsewhere in Schedule 36. HMRC's Compliance Handbook treats this as proportionality-tested in operational guidance at CH24420, which directs officers that the burden of compliance must not be disproportionately greater than the benefit to the tax enquiry.

Condition B: the identity gap

Sub-paragraph (3):

Condition B is that —
(a) the taxpayer's identity is not known to the officer, but
(b) the officer holds information from which the taxpayer's identity can be ascertained.

This is the structural differentiator from paragraph 5. Under paragraph 5 the officer has no usable leads at all. Under paragraph 5A the officer has something — a property address, a portal username, a bank-account remitter reference, a UPRN, a let-property advertisement — but cannot resolve it to a named individual without help from a business holding the corresponding customer record.

Condition C: the recipient holds the missing piece, in the course of business

Sub-paragraph (4):

Condition C is that the officer has reason to believe that —
(a) the person will be able to ascertain the taxpayer's identity from the information held by the officer, and
(b) the person obtained relevant information about the taxpayer in the course of carrying on a business.

The "in the course of carrying on a business" element matters. Paragraph 5A is not a general bulk-disclosure power against any holder of personal data. It targets businesses with customer records — letting agents, short-let platforms, payment processors, property portals, conveyancing platforms, lenders, ATED-bearing nominees. Voluntary records held by an individual or a non-business entity are out of scope.

Condition D: no easier route

Sub-paragraph (5):

Condition D is that the taxpayer's identity cannot readily be ascertained by other means from the information held by the officer.

This is a true necessity test. If HMRC could pull the same name from a Companies House filing, an SA1 link, the Land Registry register or an existing tax record, paragraph 5A is not the right route. Condition D is an evidential precondition the tribunal will test at the without-notice approval hearing — see HMRC's Compliance Handbook at CH23920.

What "relevant information" actually means — the procedural shield

The defining feature of paragraph 5A — and the most under-appreciated by recipients — is the statutory cap in sub-paragraph (6):

"Relevant information" means all or any of the following —
(a) name,
(b) last known address, and
(c) date of birth (in the case of an individual).

That is the entire output the notice can lawfully compel. Not the rent paid. Not the tenancy term. Not the bank-account number. Not the payment history. Not the property condition. A paragraph 5A notice that asks for any of those is asking for more than the statute permits, and a recipient can validly say so on appeal under paragraph 31.

Once HMRC has the name and date of birth, the officer can then issue a separate taxpayer notice under paragraph 1 — and that is the route for compelling rental-income detail. Paragraph 5A is the identity unlocker; the substantive disclosure power sits elsewhere in the Schedule.

This separation gives letting-agent and platform-operator recipients a clean procedural posture: comply with a properly-drafted paragraph 5A notice limited to name, address and DOB; resist anything beyond.

Class application: sub-paragraph (7) and the Let Property Campaign

Sub-paragraph (7), as amended by section 127 FA 2021, is the bulk-data engine:

This paragraph applies for the purpose of checking the tax position of, or for the purpose of collecting a tax debt of, a class of persons as for the purpose of checking the tax position of, or for the purpose of collecting a tax debt of, a single person (and references to "the taxpayer" are to be read accordingly).

In plain terms: one notice can demand identification data on a whole class of taxpayers at once — every landlord whose property is managed by Agent X in postcode area Y, every host whose listing appears on Platform Z. The four-condition test still has to be satisfied for the class as a whole.

This is the procedural mechanic behind HMRC's Let Property Campaign, opened in 2013 as a long-running disclosure campaign aimed at private residential landlords with under-declared rental income. HMRC has used third-party data — including letting-agent identification files obtained under Schedule 36 — to write to taxpayers and offer them a disclosure window before opening formal enquiries.

The same class-notice route was extended in 2021 by section 127 FA 2021 to support tax-debt collection where HMRC has already issued an assessment but cannot identify or locate the debtor — including derivative-liability scenarios and ATED-bearing offshore corporate structures.

Tribunal approval is mandatory

Paragraph 6 of Schedule 36 — which deals with the formalities of every paragraph-5 and paragraph-5A notice (formally extended to 5A by FA 2012 s.224(3)) — and HMRC's published guidance at CH23920 confirm that every identity-ascertainment notice must be approved in advance by the First-tier Tribunal. The hearing is without notice to either the taxpayer (whose identity is, by definition, unknown to the officer) or the business recipient.

The tribunal applies the four-condition test on the papers. There is no oral participation by the recipient at the approval stage. The four conditions are not boxes the officer ticks unilaterally — they are evidential propositions the tribunal must be satisfied of before the notice can issue.

Narrow exceptions to the tribunal-approval rule exist for parent undertakings checking subsidiaries, partners checking other partners, pensions matters, and electronic-sales-suppression tooling. For the letting-agent and platform-operator case these exceptions almost never apply.

The appeal route — paragraph 31, single ground

Once a notice has issued, the recipient's sole appeal route is paragraph 31 of Schedule 36 (extended to 5A by FA 2012 s.224(4)):

Where a person is given a notice under paragraph 5 or 5A, the person may appeal against the notice or any requirement in the notice on the ground that it would be unduly onerous to comply with the notice or requirement.

This is the same "unduly onerous" test that applies to a paragraph 30 third-party appeal — but with one key difference: there is no statutory-records carve-out and no tribunal-approval carve-out in paragraph 31. The appeal is available on the unduly-onerous ground only, heard by the First-tier Tribunal within the standard 30-day window from the date the notice is given (paragraph 32(1)).

Paragraph 32(5) makes the FTT decision final — sections 11 and 13 of the Tribunals, Courts and Enforcement Act 2007 are expressly disapplied. The only post-FTT challenge is judicial review of the original tribunal-approval decision in the High Court (Administrative Court).

A worked twelve-property class notice

Imagine HMRC's Let Property Campaign Unit has identified twelve residential addresses in central Manchester (M1 postcode) — pulled from Land Registry public records — let through a single high-street agent. The officer has the addresses, the registered freehold proprietors and rental-advertisement screenshots. The officer does not know who the beneficial landlord is in each case (registered proprietor and beneficial landlord can diverge in trust-held buy-to-let structures).

Under paragraph 5A:

  • Condition A met — checking the rental income tax position of the twelve landlords as a class
  • Condition B met — addresses and adverts held, but no landlord names
  • Condition C met — the letting agent holds a landlord file per address, obtained when taking on the management instruction (a business activity)
  • Condition D met — Land Registry shows the registered proprietor of the freehold only; the trust deed and the beneficial-ownership record sit with the agent

HMRC applies to the FTT without notice. Tribunal approves on the papers. The notice issues to the agent, demanding only landlord name, last known address and date of birth for each of the twelve files.

The agent's procedural options:

  1. Comply within the time stated in the notice (typically 30 days)
  2. Appeal under paragraph 31 on the single "unduly onerous" ground — for example, if the file count is much larger than twelve and pulling the records is a genuine production burden
  3. Judicially review the original tribunal approval — narrow window, public-law grounds only

Once HMRC has the twelve names, the next step is typically a Let Property Campaign disclosure letter to each — opening a 90-day disclosure window. If the disclosure window closes without a return, a paragraph-1 taxpayer notice (now with identity known) is the next escalation, with the Schedule 24 inaccuracy penalty regime and Schedule 41 failure-to-notify penalties on the table.

For a £400,000 Manchester rental property bought as an additional dwelling, the Stamp Duty Land Tax additional-property surcharge alone is £20,000 at current rates (5% on the full price) — useful context for how much HMRC has at stake on each individual identification.

Why this matters beyond letting agents

The same paragraph-5A mechanic now applies to:

  • Short-let platforms — where the booking platform holds host identity files but HMRC has only the property address and listing URL
  • Conveyancing platforms — where the platform holds buyer files but HMRC has only an SDLT return showing an apparent identification gap
  • Property portals — where landlord advertisers are pseudonymised
  • Payment-platform operators — where rental payments flow through a fintech with a KYC file that the property address alone does not surface

In all four, the procedural answer is the same: the notice can lawfully compel only name, last known address and date of birth. Anything beyond is out of scope and validly resistible on appeal under paragraph 31.

The data scale

In 2025, HM Land Registry registered 848,775 residential sales in England and Wales, of which 843,627 were above the £40,000 SDLT-return floor. The English Housing Survey 2023-24 puts the private rental sector at around 4.6 million households — a population almost an order of magnitude larger than any single tax year's transaction file, and one HMRC tracks via SA1, SA105 and (since FA 2012) the Schedule 36 paragraph 5A identification route.

The Bank of England's quoted-rate file shows the 75% LTV five-year fixed mortgage rate at 4.32% as at April 2026, recovered from a 4.62% twelve-month-prior peak — useful indicator of why HMRC has invested heavily in identification mechanics over the past three years. Even small-volume undisclosed-rental cases can generate non-trivial liabilities once compounded across the full enquiry window.

What recipients should do on receipt

The standard procedural checklist for a business that has just received a paragraph 5A notice:

  1. Verify the four conditions on the face of the notice — Condition D in particular is often weakly drafted
  2. Check the scope of "relevant information" — anything beyond name, last known address and date of birth is out of scope under sub-paragraph (6)
  3. Calendar the 30-day appeal window — running from the date the notice is given, not the date it is received (paragraph 32(1)(a))
  4. Decide between compliance and a paragraph 31 appeal before the window expires — any appeal must be in writing to the issuing officer and must state the grounds (paragraph 32(2))

This is general information, not advice. The Schedule 36 penalty stack — fixed £300 under paragraph 39, then up to £60 per day under paragraph 40, escalating to up to £1,000 per day on a tribunal-approved track under paragraph 49A — sits beneath any non-compliance; the wider stack is mapped in our Schedule 36 information-notice penalties piece.
