Dear All

we have a client trading since april 2007, renting a shop paying monthly rent, and paid 24K lease premium which we was amortising in accounts in 10 years , now after trading 3 years business went burst and ceased trading,

What will be accounting and tax treatment of remaining written down value of premium?

Thanks
