> Typically, you are "tax resident" if you spend more than 180 days per year in a country. (Note: that doesn't mean that if you split your time equally between three countries you avoid being tax resident at all. If only avoiding tax was that easy...)

I've been informed by my tax consultant that you are tax-resident in the country where you spent the majority of time in a year. If you split your time between three or more countries this still applies.

That's far too simplistic, sadly. It's perfectly possible to be tax resident in multiple countries - I am tax resident in two, for example, neither of which is the US.

Here's how you try and work out if you're tax resident in the UK:

There are automatic resident and non-resident qualifiers, but everything else involves a whole range of factors.

It depends in the country really. In Portugal and Spain it is really that simple, you do not live more than 180 days in a year in the country, you are not tax resident.

So if I spend 125 days in the UAE (a no income tax country) and 120 days each in 2 EU countries, I pay no income tax?
