I really did not need to send a copy of a bill or passport to sign up with gov.uk. The Revolut app was happy with an emailed photo of my passport and a selfie taken from the app itself. Local banks all have their own apps. Store loyalty cards are mostly also apps, and you can ID them from a device with RFID.
And so on.
I find the EU and UK more or less on the same level for digital services. The UK is a little behind in some ways and a little ahead in others.
The US seems to specialise in making everything unnecessarily difficult. If I want an EIN and I don't already have an ITIN, it's a letter or a fax, and it takes months. If I want an ITIN it's an officially notarised copy of my ID documents - which usually requires a trip to an embassy - and a letter. And again it takes months.
If I want to set up an LLC I have to wade through the details of 50 states, all of whom have different prices, rules, filing requirements, and local tax rates, and hire a local agent, all of whom have different prices, rules, and filing requirements.
And then the IRS can fine me $25k per infringement if they think there's a mistake on my annual filing, even though I won't be paying tax on an LLC passthrough.
Except I will because if it's a passthrough I'll probably be hit with a personal withholding tax, unless I fill in the paperwork that proves there's a tax treaty which reduces it to zero.
If some tax has already paid I can probably claim it back but I'll get a paper cheque which my bank will look at and think "Huh? Why?"
On the upside if I was living in the US I'd have to worry about incredibly expensive health insurance and payroll taxes which would make starting a small business either non-viable or very risky.
And so on. Business friendly? No.
