UK Tax Residency and the Statutory Residence Test (SRT)

The Statutory Residence Test (SRT) and UK Tax Residency Overview

• Conceptual Framework: UK tax residency is determined by the Statutory Residence Test (SRT). This status must be evaluated for each separate tax year, which runs from $6$ April to $5$ April of the following year.

• Procedural Evaluation: The SRT assesses an individual's circumstances using a strict, step-by-step hierarchy:

  • Step 1: Automatic Overseas Tests (to determine if the individual is automatically non-resident).

  • Step 2: Automatic UK Tests (to determine if the individual is automatically resident).

  • Step 3: Sufficient Ties Test (used only if the automatic tests in steps $1$ and $2$ do not provide a conclusive result).

• General Baseline for Residency: Broadly, an individual is automatically considered a UK resident if they spend $\ge 183$ days in the country, maintain a UK home for at least $91$ consecutive days, or work full-time within the UK for a period of $365$ days.

Automatic Overseas Tests (Determining Non-Residency)

An individual is classified as an automatic non-resident for a specific tax year if they meet any one of the following three conditions:

• Previous Residents (Short Stay): The individual was resident in the UK in one or more of the preceding $3$ tax years and spends fewer than $16$ days in the UK during the current tax year.

• Non-Residents (Short Stay): The individual was resident in the UK in none of the preceding $3$ tax years and spends fewer than $46$ days in the UK during the current tax year.

• Full-Time Overseas Work: The individual works full-time overseas, which is defined as averaging approximately $35$ hours of work per week. To qualify under this test, the individual must ALSO:

  • Spend fewer than $91$ total days in the UK.

  • Spend fewer than $30$ working days in the UK.

Automatic UK Tests (Determining Residency)

If the Automatic Overseas Tests are not met, an individual is classified as an automatic UK resident if they meet any of the following three criteria:

• The 183-Day Rule: The individual spends $\ge 183$ days in the UK during the tax year.

• The UK Home Test: The individual has their only home in the UK for a period of at least $91$ consecutive days. At least $30$ of those days must fall within the specific tax year being evaluated.

• The Full-Time UK Work Test: The individual works full-time in the UK for a continuous period of $365$ days. At least one day of this $365$-day period must fall within the current tax year.

The Sufficient Ties Test

If residency remains undetermined after the automatic tests, the status depends on the "Sufficient Ties Test." This test balances the number of "ties" an individual has to the UK against the specific number of days spent there.

• Types of Ties Evaluated:

  • Family Tie: This applies if the individual's spouse, civil partner, or minor children (under $18$) are living in the UK.

  • Accommodation Tie: Having accommodation available in the UK to use for $\ge 91$ days during the tax year.

  • Work Tie: Working in the UK for $\ge 40$ days during the tax year (with a "working day" defined as at least $3$ hours of work).

  • 90-Day Tie: Having been present in the UK for $\ge 90$ days in either of the previous $2$ tax years.

  • Country Tie: This applies only to "leavers." It occurs if the individual was present in the UK at midnight on more days than in any other single country during the tax year.

• Impact of Ties on Allowed Days: There is an inverse relationship between the number of ties and the number of days allowed in the UK before becoming a resident.

  • Example for Non-Residents: For an individual who was not a resident in any of the previous $3$ tax years:

    • $0$ ties allows for up to $182$ days in the UK.

    • $4$ or more ties restricts the individual to a maximum of $15$ days in the UK to maintain non-resident status.

UK Tax Implications Based on Residency Status

• Residents: Residents are typically liable to pay UK tax on all of their worldwide income and capital gains.

• Non-residents: Non-residents usually only pay UK tax on income that specifically arises within the UK.

• New Residency Rules (Effective April 6, 2025):

  • The UK will transition to a residence-based taxation system.

  • Short-term Residents: Individuals who have been UK tax residents for $4$ years or less can elect to be taxed only on their UK-sourced income and gains.

  • Long-term Residents (Inheritance Tax): Individuals who have been UK residents for more than $10$ out of the previous $20$ tax years are subject to UK Inheritance Tax on their worldwide assets.
