A client of mine is a self employed dental hygienist. She started working during February 2011. She has registered with HMRC as a tax payer for which she needs to complete a Self assessment submission by Jan 2012.
I have three questions:
1. By when does she need to pay her NI contributions - by Jan 31 2012 or by 19 April 2011 (and ,omthly thereafter)?
2. What classes on NI does she need to pay?
3. Does she need to pay provisional tax based on her earnings to 2011? If yes, if her earnings increase during the next tax year does she need to increase her provisional tax as her payment no longer reflects what she is going to actually earn?
Thanking all in advance.
