So, this year in January I started working for a company. It's only 6 or 7 hours a week and I bill per hour. About 4 times a year there are larger projects which I can take part in and boost my hours. So, every month (1st week of the month), I send an invoice. However, my first invoice wasn't sent until 16th April 2015 and covered January - March 2015 work. It wasn't really itemised.
I phoned up HMRC and they registered me as SE. I then received a tax return self assessment letter in the post. I have tried to fill it in a few times but keep stopping when it gets too hard. I really need to get it done this week so I can stop thinking about it!
So, I have just been keeping invoices. I wasn't going to claim for any expenses. I thought it would be easy. Then I hit the section on 'Date Your Books Or Accounts Are Made Up To'. HELP!
(DO I need to be keeping any other records? I don't know anyone who works SE to ask in RL)
Thank you for any advice.
