Agree that if it were that simple, taxpayers wouldn't be using us anyway! And if they enter their own data, how are we supposed to actually check whether it's correct? We'd still need documentation (for instance to check they have included the correct year!) Pie in the sky.
You'll note I said AND be 100% accurate. I didn't mention which would be quicker - just which I would prefer based on the current mess HMRC make with getting things right.
Agree with above! We simply ring HMRC if we don't have the P60s. Unless this new system is going to take less time AND be 100% accurate, think I'll stick with asking clients for their P60s and only trusting HMRC where necessary.
Erm, what's an API? some of us are technophobes
