What you need to do if you’re a contractor or subcontractor based outside the UK and do work covered by Construction Industry Scheme (CIS).
Construction Industry Scheme (CIS) covers construction work done in the UK and applies whether you’re based in the UK or abroad. There are different registration processes for sole traders, partnerships and companies.

Double taxation agreements
This is when income gets taxed in 2 countries - the one where your business is resident and the one where you earn the income. It’s an agreement between 2 countries to reduce the amount of tax that’s actually paid.
The aim is to make sure you only pay the same, or close to the same, amount of tax as you would have paid if you’d earned the income at home.
You might be able to claim back some of the CIS deductions that contractors have made from your payments if you’re a non-resident subcontractor and your country has a double taxation agreement with the UK.
You won’t be exempt from UK tax if there’s no double taxation agreement, but CIS deductions contractors make from your payments count towards your tax bill.
Your tax bill for the year will be reduced by HMRC by the amount that’s already been paid in deductions.
