Professional memberships on a PAYE based self assessment tax return

Could anyone advise how you can add valid professional memberships i.e. RICS/RIBA onto a self assessment? I have been through the tailor your return and cant find anywhere to record this i.e. which section of the form? Thx

Hi,
The professional subscription is added to the expenses section on the employment page.
On the employment page you need to answer yes to the question "Do you wish to claim any employment expenses or capital allowances while working for?"
This will then open the expenses section to complete.
Thank you.
