If you are employed, you are entitled to claim a deduction for costs you have incurred that relate “wholly, exclusively and necessarily” to your employment, which have not been reimbursed by your employer.
Annual subscriptions paid to professional bodies will be allowable provided they are paid to a body approved by HM Revenue & Customs. The activities of the body must directly benefit, or concern the profession practiced by the employee in the performance of their duties of employment.
HM Revenue & Customs publish a list of the approved bodies to which they allow tax relief for annual subscriptions (list 3 is available on the www.hmrc.gov.uk website). The Royal College of Nursing is on the list, together with a number of other bodies relating to your profession, so if you have not been reimbursed in full by your employer you should speak to your local TaxAssist Accountant to discuss the submission of a claim. You are also entitled to make a claim for up to 6 tax years previous if these also have not been reimbursed.
