Jurisdictions use different criteria to determine residency, ranging from your time in the country to your ties to it. The rules introduce the first layer of complexity to your day counting.
The amount of time you spend in different jurisdictions can change yearly. Since tax residency is evaluated annually, you must know how many days you spend in different countries.
Let’s look at the two critical conditions:
Days Spent in the Country
The critical factor for most jurisdictions is how many days you spend in the country. You are a tax resident if you pass certain days – no matter your reasons. Many countries use the 183-day threshold. For example, in the UK, one condition of the residency test is that you spend 183 days in the country during a tax year.
But countries add a layer of complexity to day counting. You may need to meet several other conditions in the UK and elsewhere, aside from time spent.
Substantial Presence or Ties
Jurisdictions also look at your presence and ties within a country to determine tax residency. The criteria don’t count only the days you spend in the country but other factors. These can include things:
-
- Where is your permanent home?
-
- How many family ties do you have to the country?
-
- What other vital interests do you have in the country?
For example, the UK has a condition where you’re likely treated as a UK citizen if you own a home in the UK and no home overseas.
Double Taxation Rules
You might be considered a ‘treaty resident’ if you’re a resident in one or two double-taxation signatory countries. Tax treaties are in place to prevent double taxation. Your tax advisor can help you understand how double taxation rules may apply to you.
