Tax on singapore income as a UK tax resident

Hello, I am considering accepting a fixed term (7 month) research job from a Singapore university, which will be fully remote (ie. I'll be working from home in the UK where I am a tax resident). I have read that there is an agreement avoiding double taxation between the two countries, will I be eligible for this? If so, how do I inform HMRC, calculate, and pay the appropriate income tax and national insurance? The income will exceed the UK personal allowance. Thanks, Ben

Hi
Please see the link to the Double Taxation Treaty in force, Double Taxation
If it is an employment contract, article 15 could apply. If it is on a self-employed article 7/14 may apply.
Please contact HMRC and request to speak to a Technician if you cannot find the information in the treaty. 

Thank you for the link. It looks like either one of these articles will apply and have the same effect, ie. only paying income tax in the UK. Is this reported via self assessment, and will this be the only route by which I need to inform HMRC to calculate the correct NI and income tax?

Hi Ben,
You are correct.
Thank you.
