"Home is where the Wi-Fi is" – How HMRC checks where you really live
"Home is where the Wi-Fi is" – I hear this phrase regularly from remote workers. It's usually said half-jokingly during conversations about work, travel, and future plans. A laptop, good coffee, fast internet – that's all you need to work from anywhere in the world.
The problem begins when this lifestyle meets the UK tax system. Because for HMRC, home isn't where the Wi-Fi is. Home is where your life genuinely unfolds. And the tax authority can verify this with greater accuracy than many people expect.
When "I'm only in the UK sometimes" stops working
I had a client who, for several years, lived under the impression that everything was in order. He worked remotely, spending part of the year in the UK and part in another country. He didn't feel "permanently settled" anywhere. On tax forms, he answered intuitively: I don't live in the UK permanently, I don't have a centre of life here.
It was only upon closer analysis that it turned out his daily life looked different from how he described it. A permanent residence in the UK. A partner living there. Regular work performed from a UK address. Days spent in the country far more often than he thought.
And this is precisely where a concept crucial to determining tax residency in UK regulations comes into play— UK ties.
What are "UK ties" and why do they matter
UK tax law isn't solely based on the question "where do you live?". Instead, it analyzes a set of factsthat demonstrate how strongly an individual is connected to the UK in a given tax year. These facts are referred to as UK ties. Importantly, their significance depends on whether the individual was a UK tax resident in previous years.
If someone was a UK resident in one or more of the three preceding tax years, the authority considers a broader range of ties. If not, the range is slightly narrower.
The mechanism remains the same: HMRC counts facts, not declarations.
Family, accommodation, work – three things HMRC checks first.
One of the key ties is family. But not in the colloquial sense. For HMRC, family means a spouse or partner living together, or a child under 18 who is actually seen in the UK. Parents in another country, even if very close, are not considered.
The second significant factor is accommodation. If a person has accommodation in the UK that is available for at least 91 days a year and they have spent at least one night there, HMRC considers it a real place of residence. Importantly, you don't have to be the owner or a tenant. It's enough for the place to be 'available' to us.
The third factor is work. If someone performs work in the UK for a specified number of days a year, even with remote work, this is also treated as a significant tie to the country.
Why days count, not impressions
The regulations very clearly demonstrate one philosophy: measurability is what counts. Days spent in the UK and nights in a given accommodation. Even contact with a child is measured by days of actual meetings. This approach can be surprising for people living 'between countries'. Because we intuitively assess our lives through the lens of plans, intentions, and a sense of temporariness. However, HMRC looks at the calendar, addresses, and patterns of behaviour.
And this is precisely why many people only realise after a detailed analysis that their tax situation is different from what they expected.
When the sum of small things starts to matter
Most often, it's not about a single element. It's rare for someone to trigger tax residency due to one accommodation or one contract.
It's more likely combination of facts: a few days in the UK, a permanent address, a partner living there, regular work, returning year after year. Each element on its own might seem insignificant. Together, they create a clear picture for HMRC.
And that's why it's so important to look at your situation holistically, not just in isolation.
Residency isn't a label; it's a consequence of facts.
Tax residency isn't something you "choose." It's a result of how your life truly looks: where you live, with whom, how you work, or how often you return. And while the saying "home is where the Wi-Fi is" sounds good over coffee, something entirely different matters when dealing with HMRC. What matters is your daily life, documented by facts.
If your life spans across countries, it's worth looking at it through the system's eyes before the system does it for you. And that's exactly what we help with at TaxOne.
Why this isn't a task for standard accounting
Determining tax residency isn't just about booking documents or filling out declarations. It's an analysis of regulations, life circumstances, and their interdependencies, often across more than one legal system. Accounting deals with what has already happened. Residency concerns how the tax authority will interpret your life.
And that requires knowledge of tax law, not just accounting.
If you live between countries, work remotely, or are planning changes, this isn't a topic to put off "for later." This is the moment to check your situation before the tax authority does. If you have doubts about how your life looks from the perspective of UK tax law, contact us. At TaxOne, we'll help you analyze and organize it before unnecessary risks arise.
