Have you received an HMRC “nudge letter” regarding a property in the Royal Borough? Felix Accountants provides specialist tax disclosure services for Windsor landlords to resolve undeclared income discreetly and efficiently. Receive Let Property Campaign expert help from Felix Accountants.
Windsor is home to some of the UK’s most prestigious residential real estate. Whether you own a period townhouse near Windsor Castle, a luxury apartment in Eton, or a family home in Old Windsor, the rental yields are significant—and so is HMRC’s interest in them.
In 2026, the Royal Borough of Windsor and Maidenhead (RBWM) has tightened its data-sharing protocols. If you have been renting out a property in Windsor without notifying HMRC, the “window of opportunity” to come forward voluntarily is closing. Felix Accountants is here to help you navigate the Let Property Campaign with professional precision.
Why Windsor Landlords are Currently Under Scrutiny
HMRC’s “Connect” AI system is particularly active in high-wealth postcodes like SL4. Local factors contributing to the recent surge in nudge letters include:
-
Short-Term Let Popularity: With Windsor being a global tourist destination, many homeowners use sites like Airbnb for weekend lets. Since 2024, these platforms share all host data directly with HMRC.
-
The “Commuter Shift”: Many Windsor professionals have moved further out or abroad, keeping their Windsor homes as investments. Often, these “accidental landlords” fail to realize they need to file a UK tax return even if they live overseas.
-
RBWM Licensing & Planning: The Royal Borough’s focus on planning permissions and HMO standards creates a public record of property use that HMRC cross-references against self-assessment filings.
The Felix Accountants Advantage for Windsor Clients
High-value rentals require a more nuanced approach to tax disclosure. We offer Windsor landlords:
1. High-Value Expense Optimization
With Windsor property maintenance and management fees often being higher than the national average, we ensure every “allowable expense” is captured. From Crown Estate related charges to premium management fees, we maximize your deductions to lower the taxable profit.
2. Discretion and Professionalism
We understand the need for privacy. Our service is highly confidential, acting as the sole point of contact between you and HMRC. We manage the 90-day disclosure clock to ensure your affairs are settled without the need for a face-to-face HMRC audit.
3. Specialist “Non-Resident” Support
If you have moved away from Windsor but still hold property there, we manage your Non-Resident Landlord (NRL) status. We help you claim back any tax overpaid by your letting agent and resolve historical gaps via the Let Property Campaign.
Local Knowledge, National Authority
At Felix Accountants, we don’t just know the tax code; we know the Windsor and Eton property landscape. We understand the difference between a long-term professional let in Clewer and a high-turnover holiday let near The Long Walk. This local context allows us to argue more effectively for “Reasonable Care” when negotiating your penalty percentages.
Take Action Before the “Nudge” Becomes an Enquiry
In Windsor, a formal tax enquiry can be intrusive and costly. By using the Let Property Campaign unprompted, you stay in control of the narrative and the cost.
