Well i am pretty pleased with the result of filling in my first ever tax return online, i managed to do it before the cutoff date of 31st January and in the end although i went over the capital gains tax limit by £99 meaning i owed around £17 in capital gains tax, they actually owe me £42 for over payed income tax.
This will be easy to do next year until they say i don't need to do it again.
