State Pension (the amount for the year) is auto filled. The figure in the box is correct for 52 weeks at the DWP benefit statement. However, in reality the pension received in the tax year is less because the used increased pension rate does not start until April 12th. I would expect for tax purposes the actual pension received over the tax year is the relevant figure which in my case is some £13 less.
Should I correct this figure to actual pension received?
Note: I did try to follow the correction process but keep getting an error message for the reason for amendment, regardless of what I enter into the box. I have tried numerous formats to no avail.
