A deal was agreed between negotiators for the EU and UK on Christmas Eve and the extraordinary States meeting will look at what the 1,200-page document means for the islands.
A policy letter has been published which includes seven main points for deputies to consider.
These include approving the principles of the future relationship of the UK and EU; authorisation for the Policy & Resources Committee to agree and signal the Bailiwick's agreement to the deal; and to agree that the States will work on VAT, customs and excise arrangements with the EU in light of the deal.
The policy letter also notes that the extension of the UK's World Trade Organisation membership will come into effect from the end of the year; and notes the inclusion of the Bailiwick in various free trade agreements 'rolled over' by the UK.
It also notes that customs arrangements between the UK and Bailiwick will come into effect at the end of the year and directs that all island legislation necessary is put into force.
