Reversal of wrongly claimed depreciation

Hi,4-5 years back I have filed one 1120S tax return in which there were some fixed assets i.e. Land & Building legally entitled to the owners and since then I am claiming depreciation on that in business return and not claiming any depreciation on personal return. But in 2007 tax return need arises to consider this property belonging to owner and no more to be retain on books, for this in 2007 rent has been paid to owners.Now I can not go back and file amended tax returns for so many years and if I consider it to the transfer of asset I need to take the fair value and I can not take the book value which in reality I am transferring back to owners. I have adjusted my books by adjusting capital accounts, fixed asset accounts and depreciation accounts but how can I treat it for tax return purpose. My intention is just to remove the assets from books. Please guide me on this issue.Thanks in advance,Janak
