From current 2026/27 rules to historical data back to 2022/23. Clear guidance on SDLT, rental income, and how to handle HMRC nudge letters and property compliance checks.
Property tax in the UK is not a "one-size-fits-all" regime. Whether you are buying a first home, managing a portfolio of rentals, or dealing with a complex corporate property structure, the rules change significantly based on the date of the transaction and the nature of the ownership.
Crucially, we recognize that many taxpayers are not just looking forward to 2026/27, but are looking backward. HMRC has significantly increased its use of digital data matching—using Land Registry records and bank data to identify undeclared rental income or under-declared Stamp Duty. If you have received a "nudge letter" or are facing a compliance check for years as far back as 2022/23, using the wrong year's thresholds can lead to incorrect disclosures and higher penalties.
This hub provides a direct path to factual guidance on every property tax, paired with historical allowance tables and a specific framework for dealing with HMRC investigations. Our goal is to provide the clarity you need to correct your records and resolve disputes efficiently.

A Nudge Letter is an informal prompt. HMRC is telling you they have data (from the Land Registry, banks, or platforms) and are giving you a chance to "correct" your return voluntarily. They typically do NOT provide the specific evidence at this stage.
A Compliance Check is a formal investigation. In these cases, HMRC officers are generally required to disclose the scope of their check and the specific reasons for the investigation.
Identify exactly which years HMRC is questioning. Are they referring to the 2023/24 year, or are they going back to 2022/23? Note any specific property addresses mentioned.
You can contact HMRC to see if they can provide a clue as to why the letter was sent. However, be aware that with nudge letters, they often refuse to provide detailed data to encourage "voluntary" disclosure.
Cross-reference your rental income or purchase prices against the Historical Rates Matrix in our sub-guides. Check your bank statements against the dates HMRC is targeting.
Contact previous solicitors, tenants, or letting agents. It is common for third-party providers to report incorrect information to HMRC, triggering a nudge letter that is actually based on a mistake.
If an error is found, a voluntary disclosure before a formal investigation begins often results in significantly lower penalties. Do not simply "ignore" a nudge letter; it is often the prelude to a full audit.
HMRC property investigations are high-stakes. A mistake in a voluntary disclosure can lead to accusations of "careless" or "deliberate" inaccuracy, which dramatically increases penalties. We can match you with a verified tax professional who specializes in property compliance and HMRC dispute resolution to handle the communication for you.
