I have good news, we are now able to accept customers who are US citizens but who are resident in the UK. Tell your wives, friends and family!
As this thread points out under FATCA (Foreign Account Tax Compliance Act) we are required to report for any of our customers who may have tax responsibilities in the US. This means in app when you’ve opened your account you might be prompted to confirm whether you have any tax responsibilities outside of the UK, and if you answer yes and select United States you will be asked to provide your TIN (Tax Identification Number) too. If you have tax responsibilities elsewhere it if your responsibility to report this to us accurately. We will be updating our current account terms and conditions to reflect this change in due course as well.
If you do have a relationship with the United States and a need to send money to and from the States, it is worth noting that your Starling account will be held in GBP and we cannot, at this time, accept incoming payments in US Dollars.
