married allowance

I claimed married allowance a few years ago and then cancel it. Now, I want to claim again. but I forgot the married date which I input at first time. Then, the system said my married date is wrong. How can I find out the married date which I input at first time?

Hi

The date of marriage you entered to claim the marriage allowance transfer should have been the date you got married.
Please try entering this date, before contacting us via Income Tax: general enquiriesfor more assistance if necessary.

Thank you
