Tax in Danish Sector

Hi all - i want to pick your brains about Danish tax offshore.

I run as a UK Ltd Co. - i am a UK resident.

I have been offered a short contract for a UK ROV operator, (for a vessel based, ROV job offshore Denmark - they will be sub contracted to another company), and wondered what the possible tax implications are for me and my company, (ie. income tax and corporation tax).

The last time i worked out there it was on a wind farm job, and as such, it didn't incur the full force of the Danish tax system.

Do companies still give a 10% uplift as per Norway to cover any extra tax liability?

I know there is a dual taxation agreement between UK and Denmark, but it may as well be written in a foreign language for all the sense i can make of it.

I have been in touch with HMRC but their reply could take a week - job may be gone by then.

So, any thoughts would be welcomed, so i can make my mind up to go or wait for another job.

Thanks in advance.
