Hello and welcome to the site. Thank you for your question.Boxes 24 to 29 cover property expenses. Rent would relate to ground rent payable under a lease of a property and not rent lost because the property is vacant.Your best course of action is to accept there was an inadvertent error due to misunderstanding of what goes in that box and provide correct figures for Box 24.Also provide correct figures for Box 24 covering your tax return 2012-13. As you would be instigating a correction to the last return (2012-13) there would be no penalty for understatement of profit. You can make corrections to your tax return 2012-13 upto 31 Jan 2015 without incurring any penalties.More information on this can be found under "Correcting your return" here
I hope this is helpful and answers your question.
If you have any other questions, please ask me before you rate my service – I’ll be happy to respond.
Hello, thanks for that. Re. rental payments I had to make, where should that be stated?
Yes, 3 payments of 500 pounds, amounting to the value I entered incorrectly in box 24.
