If you have been ebay selling only since July this year there isn't a big problem, as you will not have accumulated any arrears.
You should register as self-employed as soon as possible; if your expected profits, after expenses, will be less than £5315 in this tax year, you can claim exception from class 2 national insurance. You will need to complete some sort of accounts for your first trading period (the easiest year end to use is 5 April or 31 March) , but these can be quite simple if turnover is low. If you do not have full records, a resonable estimate of expenses will be acceptable.
You can register as self-employed by telephone, or by completing a form CWF1 which can be downloaded from HMRC website, and you will be sent a self-assessment tax return after 5 April 2012.
