Yep - it's terrible
I spend most of my time writing Payroll software. The old HMRC site was brilliant. You had a big section for all the stuff you may want to know - it's like they listened and made it easy. The new site makes me think that they are deliberately trying to annoy me!! Information I used to have easily to hand is now obtainable by GUESSING and editing links to other information! Some of our support staff just gave up sating that information they need to do their jobs doesn't exist any more. I've had to make a mini HMRC page that's links to all we need to know.
Still it looks nice - oh hang on - it looks terrible - huge text, wasted space, horrible colour scheme.
