You’re a tax resident if you spend 183 days or more in Australia during the income year (not calendar year), even if not continuously. This includes your arrival and departure dates. To stay non-resident, you must not exceed 182 days.

We have encoded France’s visa-based residency rules to monitor. If you hold a long-stay visa equivalent to a residence permit (VLS-TS):

• You can stay in France for up to 6 months, typically counted in calendar months, not days

• The visa must be registered within 3 months of arrival

• You must leave on or before the visa expiry date shown in your passport

If you hold a 3-month long-stay visa (VLS-T):

• You can stay for up to 3 months

• The visa is non-renewable, and you must depart before expiry

You’re a tax resident if:

• You ordinarily reside in Hong Kong, or
• You’re present for 180+ days in a year, or 300+ days across two years

India applies a 182-day rule. All days you are physically present, including arrival and departure days, are counted.

To be non-resident, you must not exceed 181 days in the tax year.

You’re tax resident if you spend:

• 183+ days in a single year, or
• 280+ days across two consecutive years (with 30-day minimum in either year)

You will not be considered resident if you’re in Ireland for 30 days or fewer in a tax year.

To be non-resident, stay under 183 days in one year and under 280 days over two.

In Jersey, short term business visitor status is primarily determined by the number of days an individual spends in the island within a calendar year. From 2024, short-term business visitors are not liable for income tax if they:

• Spend 60 days or fewer in Jersey in the calendar year

This includes arrival and departure days, and the count is cumulative throughout the year.

Under the Non-Habitual Resident (NHR) regime, you are considered a tax resident if you:

• Spend more than 183 days in Portugal in a 12-month period (consecutive or not), or

• Maintain a habitual residence at any time during the year.

To establish tax residency, you must spend 183+ days in Monaco within a rolling 12-month period. Residency is confirmed through the Carte de Résident and proof that Monaco is your primary home. You can read more about Monaco residency in our article ‘How to Become Resident in Monaco’.

The rule is simple, but hard to count manually:

90 days in any rolling 180-day period across the 27 Schengen countries. Every day you’re physically present counts, even partial days. Our app includes  open-border microstates like Andorra, Monaco, San Marino, and Vatican City to the Schengen Rule. You can learn more about Schengen in our article on Schengen travel.

You’re a tax resident if you’re physically present in Singapore for 183 days or more in a calendar year.

Tax residency is triggered if you spend more than 183 days in Spain in a calendar year.
Temporary absences generally still count unless you prove tax residence elsewhere.

You are tax resident in Switzerland if any of the following apply:

• You intend to establish your usual abode and register with municipal authorities

• You stay for 30+ consecutive days with the intention to work

• You stay for 90+ consecutive days without working

To be non-resident, you must:

• Stay fewer than 30 days if working

• Stay fewer than 90 days if not working

Short absences (e.g. weekends away) do not reset the count.

You’re a tax resident if:

• Present in the UAE for 183+ days in a consecutive 12-month period, or
• Present for 90+ days in a consecutive 12-month period and meet additional criteria (e.g. employment, permanent home)

The UK uses the Statutory Residence Test (SRT) to determine tax residency. There are three parts: Automatic Overseas, Automatic UK, and the Sufficient Ties Test.

You are automatically UK tax resident if you:

• Spend 183+ days in the UK during the tax year.

You are automatically non-resident if:

• You spent fewer than 16 days in the UK and were UK resident in any of the previous 3 tax years,
• Or you spent fewer than 46 days and were not UK resident in any of the previous 3 tax years,
• Or you worked full-time overseas, and:
  • Spent fewer than 91 days in the UK,
  • Worked more than 3 hours on fewer than 31 UK days,
  • Had no significant break (31+ days without working or valid leave) from overseas work

If none of the above apply, the Sufficient Ties Test is used.

This test looks at your UK connections, including:

• Having a UK home
• Having a UK-based job
• Spending more time in the UK than any other country
• Having close family in the UK
• Spending significant time in the UK in recent years

The more ties you have, the fewer days you can spend in the UK before becoming a tax resident.

 These rules apply to both employees and the self-employed. Voluntary workers and transport workers (e.g., ships, planes) follow separate rules.

You can explore the UK SRT more through our case study.

You are considered a U.S. tax resident if:

• You spend 31+ days in the U.S. during the current year, and
• 183 days during the 3-year period that includes the current year and the 2 years immediately before that, counting:
  • All days you were present in the current year, and
  • 1/3 of the days you were present in the first year before the current year, and
  • 1/6 of the days you were present in the second year before the current year.

To be non-resident, you:

• Can’t spend more than 30 days during the current year
• Must ensure your 3-year weighted total is 182 days or less if staying for more than 30 days

A common rule of thumb: 120 days per year keeps you under the threshold.

There are also excerpted individuals whose presence in the US doesn’t count. These include:

• Diplomats and consular officers and their immediate family members
• Students on F, J, M, or Q visas
• Teachers/trainees on J or Q visas and their immediate family members
• Professional athletes temporarily in the country to compete in a charitable event

You become tax resident if you stay in Vietnam for:

• 183+ days in a calendar year or
