The EEA-EFTA Separation Agreement and the Swiss Citizens’ Rights Agreement

The EEA-EFTA Separation Agreement is the Agreement between the UK and the EEA-EFTA States (Norway, Iceland, and Liechtenstein) on protecting citizens’ rights and resolving separation issues as the UK exits the EU; and

The Swiss Citizens’ Rights Agreement is the agreement reached with Switzerland on protecting citizens’ rights and resolving separation issues as the UK exits the EU.

These agreements provide the same protections of residence and SSC rights as Part 2 of the WA for nationals of Norway, Iceland, Liechtenstein and Switzerland. The WA and these agreements also extend to nationals of the EU, the EEA-EFTA States and Switzerland. Any reference to the WA in the following content should also be read as a reference to the EEA-EFTA Separation Agreement and the Swiss Citizens’ rights Agreement.

In scope of the WA

UK, EEA-EFTA and Swiss nationals currently in receipt of Child Tax Credit, in scope of the WA will continue to receive and export Child Tax Credit in respect of children living in EU Member States, the EEA-EFTA States or Switzerland.

UK, EEA-EFTA and Swiss nationals currently in receipt of Child Tax Credit who have a right to reside in the UK or are subject to UK legislation at the end of the IP, 31 December 2020 are in scope and can continue to receive Child Tax Credit and this can be exported for children residing in EU Member States, the EEA-EFTA States or Switzerland. Full rights under the WA and Regulation (EC) Nos 883/2004 and 987/2009 continue to apply.

Out of scope of the WA

UK, EEA-EFTA and Swiss nationals currently in receipt of Child Tax Credit who do not have a right to reside in the UK or are not subject to UK legislation at the end of the IP, at 31 December 2020 do not fall in scope of the WA and will not have access to benefit.

EU Settlement Scheme (EUSS)

EU, EEA-EFTA and Swiss nationals currently in receipt of Tax Credit are required to apply to the EUSS to be granted an immigration status:

  • Settled Status for those who have been in the UK for five years or more
  • Pre-Settled Status for those who have been in the UK for less than five years

Third country nationals who are currently in receipt of Tax Credit and are family members of EU, EEA-EFTA and Swiss nationals are also required to apply to the EUSS.

Home Office New Immigration System

The new Home Office Future Border Immigration System went live on 1 January 2021. All non-UK [or non-Irish] nationals are required to apply to either EUSS or FBIS for an immigration status.

Grace Period

EU, EEA-EFTA or Swiss nationals currently in receipt of Tax Credit, resident in the UK and in scope of the WA, must apply to the EUSS if they do not have an existing valid immigration status.

A “Grace Period” was introduced in line with the WA from the end of the IP (31 December) 2020 until 30 June 2021 to provide time for EEA-EFTA and Swiss nationals with time to apply for a domestic immigration status. EEA-EFTA and Swiss nationals resident in the UK before the end of the IP, and their family members, were not required to have an immigration status during this period. However, they are required to have applied for a status by the end of the Grace Period to legalise their stay in the UK.

The deadline for applying to the EUSS was 30 June 2021. However, you may still be able to make a late application.
