He Thought Everything Was Fine Until SJW Discovered That HMRC Had Already Started Issuing Penalties

— Professional property management is not just about managing a property. It is about protecting overseas landlords from risks they may not even know exist.

Many overseas landlords believe that a property management company’s role is limited to finding tenants, collecting rent, arranging maintenance and carrying out routine inspections. At SJW Property Management, we see our role very differently. Looking after a rental property is only one part of what we do. For overseas landlords, the greater risks often lie behind the scenes—in taxation, compliance, legal obligations and long-term asset management. These issues are rarely visible until they become serious, and by then they can be far more costly than a maintenance issue or an empty property.

This landlord owned two rental properties in London when he first appointed SJW Property Management. One apartment, located in Central London, was transferred to SJW for full management, while the second property continued to be managed by another property management company. From the landlord’s perspective, everything appeared to be running smoothly. Both properties were tenanted, rental income was arriving regularly, and there seemed to be no reason to believe that anything required attention.

The situation changed when Maggy, a member of SJW’s finance team, began reviewing the landlord’s rental accounts and financial records as part of the onboarding process. During her review, she discovered something unexpected. The landlord had never completed the necessary tax reporting required under the UK’s Non-Resident Landlord (NRL) Scheme. When Maggy discussed the matter with him, he was genuinely surprised. He had always assumed that because a property management company had been managing his rental properties, the tax side of things had naturally been taken care of as well. It was only during that conversation that he mentioned he owned a second rental property, which had also never been properly reported for UK tax purposes.

This is a situation that is more common than many overseas landlords realise. Rent continues to arrive every month, management reports are sent regularly, and everything appears to function normally. As a result, many landlords understandably assume that all compliance requirements have been dealt with. Unfortunately, the UK tax system does not work that way. Whether or not a landlord is aware of their obligations, HMRC still expects overseas landlords to comply with the relevant tax rules. Failure to register or submit the required tax information does not simply disappear over time. In many cases, penalties begin accumulating long before the landlord even realises there is a problem.

Once the issue became clear, Maggy immediately began reviewing the landlord’s entire tax position. She gathered historical rental records, payment histories and tax documentation before helping him organise the information required for his overseas landlord tax affairs. During this process, however, another complication emerged. Years earlier, the previous property management company had already applied for a Non-Resident Landlord Number on the landlord’s behalf. The application itself had been completed, but the subsequent tax reporting had never been properly submitted. As a result, HMRC had already begun applying penalties to that tax account, although the landlord had never been informed and had no idea the account even existed.

At this point, SJW could easily have limited its work to the property under its own management. Instead, the team took a different approach. Although the second property had never been managed by SJW, Maggy believed that solving only part of the problem would leave the landlord exposed to future risks. She therefore combined the financial records from both properties, reconstructed the landlord’s overall rental income history and worked to resolve the tax position across the entire portfolio rather than treating each property separately.

SJW then worked directly with HMRC to explain the historical situation, reconcile the landlord’s rental income records and review previous tax payments. Following detailed discussions and careful examination of the accounts, HMRC agreed to retain one Non-Resident Landlord Number, cancel the duplicate account and consolidate all records into a single tax profile. More importantly, the penalties that had begun accumulating on the unused account were removed, allowing the landlord’s tax affairs to be brought back into full compliance.

What happened next surprised everyone involved. Once every year’s accounts had been carefully reconciled, HMRC concluded that the landlord had actually overpaid tax during certain tax years. Instead of receiving an unexpected tax bill, he received a tax refund of more than £4,000.

For the landlord, the refund was certainly welcome. However, the greatest value did not lie in the amount of money returned. The real achievement was that years of incomplete records, duplicated registrations and unresolved tax issues had finally been organised into a clear, accurate and fully compliant tax structure. From that point onwards, his rental income, tax reporting and Non-Resident Landlord status were all properly managed, giving him confidence that his UK property portfolio was built on solid foundations for the future.

Afterwards, the landlord told the SJW team that he had always believed property management was simply about renting out a property. He had never imagined that a professional property management company would proactively identify problems that he himself did not know existed. He was equally surprised that SJW was willing to help resolve tax issues relating to a second property that was not even managed by SJW. It was through this experience that he came to understand the difference between simply managing a rental property and genuinely protecting a landlord’s long-term interests.

At SJW Property Management, this is exactly how we define professional property management. Managing a property is only part of our responsibility. We also help overseas landlords manage compliance, taxation, legal obligations, financial risk and the long-term security of their UK assets. The best property management is not measured by how efficiently problems are fixed after they appear. It is measured by how many problems are prevented before the landlord even knows they exist.
