Hi there ,Id highly recommend to do it on line if your only doing nails part time, as long as your organised with your paper work its pretty straight forward.If you give your local inland rev . a call they should be able to book you on a free course to show you how its all done.I done mine for the year before last ,last year,and Ive nearly completed mine this year for last year .The good thing about doing it online is you get a longer deadline,and you get a sum of what you owe or dont owe

straight away in front of you.
Yes I think it is £5K you can earn before you get taxed(4,5or6)somebody else could probly confirm that.I do nails part time,and my first year of online tax ,I got a rebate!!well chuffed!!
