Everyone in Northern Ireland who is eligible for the Self-Employment Income Support Scheme (SEISS) will be able to claim their grant. People who have engaged with HM Revenue & Customs (HMRC) online in the past using an existing Government Gateway credential – for example, to file their Self-Assessment tax return – can reuse their existing online Government Gateway credentials to claim the grant. Most people who are eligible to claim have credentials already. Those dealing with HMRC online for the first time will be required to verify their identity. HMRC worked quickly with the Driving and Vehicle Licensing Agency to enable people to use a GB driving licence to verify their identity for SEISS. It has not been possible to add non-UK passports or non-GB driving licences to the Government Gateway authentication service to the same timeline. HMRC are currently exploring whether it is possible to connect to Northern Ireland Driver & Vehicle Agency (DVA) and Irish Passport Service data, as part of their continuing improvement of the Government Gateway. People who do not have a UK passport or GB driving licence can use the multiple-choice questions option to verify their identity. This uses a financial checking service that does not require a passport or driving licence. Anyone who is unable to verify their identity in this way can also make their claim by telephone.
