That would be ridiculous. As an agent I have full access to all my client's tax information. Can speak to HMRC about it in detail, can submit any information and also adjust it after the fact.
Plus if my client is due a tax refund, with their permission I could get it paid to me (I don't btw as I don't want the complications of a client account).
GDPR? I already know more about my clients information than they do. I regularly get "could you send me my NI number" type messages.
It would be pure madness for all self employed people who use an accountant to have to then set up their own government gateway accounts and claim that way. That's millions of people.
And especially when they'd then have to contact their agent for the information to submit anyway.
You're probably right but I really hope you're wrong as that's just crackers!
I totally agree with everything you say . It's pedantic. But to be honest GDPR is actually over pedantic as it stands anyhow
