My company is being dissolved and I was trying to file my final corporation tax, yet every time I do it get errors like "previous accounting period must be before 1st March 0023 (not the double 00 and not 20)", and then when i try to type in a date that should be my previous accounting date it says they can't match the data and for me to contact the HMRC. But the accounting dates are correct? Could someone please assist me?
