@iloveyouguys I think this depends how you make money. You can be due taxes without being tax resident; for example if you manage a business from your temporary country, service clients
in your temporary country, service clients
from your temporary country or have some other economic activity.
To quote a prominent racing driver who lives in Monaco, quoted in The Sunday Times' Style magazine:
You should be able to hop around Europe, spending your existing wealth or living on︀ dividends from companies that you do not work for, manage or control. e.g. I can︁ imagine someone living on income from NASDAQ shares while backpacking around the EU, without paying︂ EU taxes. But if you do work in some country or manage a business from︃ there then you might be due tax there.
Surely article 4 paragraph 2 only applies to someone who is liable to︆ tax "by reason of his domicile, residence, place of management or any other criterion of︇ a similar nature" in UK and Denmark? Unless Denmark taxes domicile, I don't see the︈ issue.
The real issue in the example seems to be "earning money from the UK",︉ which with 0 days spent there sounds like it's due to maintaining some office or︊ factory, or maybe the future tech tax or similar. I do agree that if not︋ resident in either, then Danish taxes might be worse than UK taxes so the DTA︌ could work against such a person.
It is usually more complex. I'll pick the UK (only because I know this︎ one):
- Non resident if:
- Present for fewer than 16 days
- Present for fewer than 46️ days, if not resident in the preceding 3 years
- Present for fewer than 91 days, working in the UK less than 31 days and otherwise working abroad full time
- else resident if in the tax year:
- Present for 183 days or more
- Present in your UK home for 30 days or more
- Work full time in the UK
- else it varies from 16 to 182 days in the UK, depending on:
- UK resident family
- Available accommodation (even if you only spend 1 night there)
- UK employment for 43+ days
- Presence of 90+ days in either of the previous two tax years
- More days in the UK than any other country (only if leaving UK, not if arriving)
So to take that example, the limit is 182 days only if the you can answer the other 10 questions in a particular way. Other countries have different rules, sometimes much simpler (183︀ days) and sometimes much more vague (centre of vital interests). People have gone to court︁ based on where they keep their golf clubs or SCUBA gear.
In some countries, not all. For︃ example in Ireland you need to provide the PPS number if you're resident and want︄ to get a loan or credit of EUR500+ or to get your bank interest paid︅ without tax deducted. Some banks require PPS anyway, but not all. There is a lot︆ of variety to these types of rules.
