What Is the Sufficient Ties Test
The Sufficient Ties Test is part of the Statutory Residence Test and is used when neither the Automatic Overseas Tests nor the Automatic UK Residence Tests apply.
HMRC uses this test to assess how strong your connections to the UK are and how many days you spend here during the tax year. The outcome depends on both factors together. The more ties you have to the UK, the fewer days you can spend here without becoming UK resident.
This test is often the most complex part of the residence rules and is where many people become unintentionally UK resident.
Who This Test Applies To
The Sufficient Ties Test applies if you:
Do not meet an Automatic Overseas Test
Do not meet an Automatic UK Residence Test
Spend time both in the UK and overseas
Retain some ongoing UK connections
It commonly affects people working abroad who return regularly to the UK, those with UK accommodation or family ties, and individuals transitioning into or out of overseas work.
The UK Ties Explained
Family Tie
You have a family tie if your spouse, civil partner or minor children are resident in the UK. This tie applies even if you spend limited time together in the UK during the year.
Accommodation Tie
An accommodation tie exists if you have a place to live in the UK that is available to you for a continuous period and you spend at least one night there during the tax year. This can include property you own, rent or have access to through family or friends.
Work Tie
You have a work tie if you work in the UK for at least 40 days during the tax year. A work day is counted when more than three hours of work are carried out in the UK on that day.
Ninety Day Tie
This tie applies if you spent more than 90 days in the UK in either of the previous two tax years. It reflects a pattern of regular UK presence.
Country Tie
The country tie applies only to people who were UK resident in one or more of the previous three tax years. It exists if the UK is the country where you spend the greatest number of days during the tax year.
How Day Counts and Ties Work Together
Under the Sufficient Ties Test, your UK residence status depends on both the number of UK ties you have and the number of days you spend in the UK during the tax year.
As the number of UK ties increases, the maximum number of days you can spend in the UK without becoming resident decreases. HMRC uses fixed thresholds to determine when residence applies.
We calculate your ties and day counts together to confirm whether you remain non resident or become UK resident for the year.
Where People Often Get Caught Out
Many people underestimate how easily UK ties can apply, particularly accommodation and work ties. Short visits, remote working and informal access to property can all affect the outcome.
Another common issue is failing to track UK days accurately. Even small miscalculations can push someone over the residence threshold.
We review your full circumstances to avoid these problems and give clear guidance on managing UK visits.
Supporting Your Residence Position
HMRC expects clear records to support claims under the Sufficient Ties Test. This includes travel records, accommodation details, working day logs and information about family circumstances.
Good record keeping allows your residence position to be demonstrated clearly and reduces the likelihood of enquiries or disputes.
