SA109 Box13

Split year Case 4 is applied to me so I've put ‘X’ in box 3.　I have worked more than 3 hours in UK during 2022/2023 tax year. I have also filled the SA102 for the employment in UK. Do I need to fill in the no. of days I worked in UK during 2022/2023 tax year? Thanks

Hi victor,
If you put ‘X’ in box 3:
•    you must include details of which split year case 
applies to you in the ‘Any other information box. 
Box 40:
•    do not put ‘X’ in box 1, but fill in box 6
•    put the number of days spent in the UK for the
overseas part of the tax year in box 10.
Thank you.
