Hi Rebecca Foy,
As your self employed income is over the Small Profits Threshold you may be liable for an element of Class 2 as well as Class 4 although the high Cl1 earnings will be taken into account and can reduce both Cl4 and Cl2 depending on the amount of Cl1 paid.
As we are unable to be specific on this Forum is best you call our
NI helpline to discuss the account with specific information so a correct answer can be given.
Thank you.
