Your state pension might be affected if you're transgender and you:
Were born between 24 December 1919 and 3 April 1945
Were claiming the state pension before 4 April 2005
Can provide evidence that your gender reassignment surgery took place before 4 April 2005
You don't need to do anything if you legally changed your gender and started claiming state pension on or after 4 April 2005 – you'll already be claiming based on your legally recognised gender.
