I started the registration process last week as I wanted to do what you have done and have a look around the online system, but when I came to the end I wasn't happy with agreeing to be bound by the T&Cs to file online without having viewed the online system first. so I cancelled the process.
As for your filing, was it accepted and what was the result? Did you have to provide supporting docs? Did you submit PND90 or PND91 and how did you decide which one to use?
Do you have remitted income that is covered by the DTA? If yes, did you report it?
Do you have remitted income that has already been taxed in the UK? If yes, did you report it?
Sorry for all the Q's but I'm just trying to gather as much info as I can
Thanks in advance.
