Employee working from Dubai - company requirements

I've recently started working for a UK company, remotely from Dubai (lived here for 10 years). I'm on my employer's PAYE scheme and currently paying tax as I'm not sure how many days I'll spend working in the UK per year. I'm happy to carry on doing this. The company have asked me to find out if they need to provide anything to HMRC? Thank you.

Hi,

You can continue with your employment being taxed as it is at the moment or your UK employer can apply to HMRC for a direction to operate PAYE on your earnings, by submitting an S690 application.

Thank you
