The Home Office, HM Revenue & Customs and the Department of Work and Pensions (DWP) will all share data they have on individuals in a number of key areas as part of a cross-departmental Brexit immigration system.
The idea is to create an online method for employers and public service providers to check the identity, employment and rights of EU citizens based in the UK.
A leaked Home Office document, seen by The Guardian, dated August 2017, proposes a phased introduction of a new immigration system, which would be "as digital, flexible and frictionless for individuals and employers as possible".
A digital portal will be created, whereby employers can check the immigration status of an individual "and take action if necessary".
This will be supported by "improved data-sharing capabilities between government departments, notably between the Home Office, HMRC and DWP, to link together tax, benefit, and immigration records in a fully automated and digital way".
Initially, it is likely that physical documentation and manual methods will be used by the government for UK citizens to prove they have the right to stay in the country.
However, Whitehall said its intention was to replace this with a fully digital process as soon "as it is operationally feasible".
During the implementation phase, the government will be taking in the views of employers and other stakeholders to ensure the system works as intended.
There is no indication of how long each stage of implementation would take, who is responsible for creating the digital portal, or when it is likely to be completed.
