UK Tax Advice

I have a job offer and all being well will head out to Bahrain from England by the end of June.

The contract is for a minimum period of 2 years. The Statutory Residence Test Guidance Note(HMRC) states that I can work for 30 days in the UK, spend less than 90 days back in the UK and qualify for the third automatic test eg Non resident.

I am intending to take some paid annual leave during my stay(till the end of June) in the UK and I am wondering whether it will be accounted towards the 30 day margin.

It seems like if I leave the country by the end of June, it will be too late and I will be liable to pay UK tax.

If this is not the place for tax questions can someone advise of a professional who can assist?

Many thanks
