let suppose the liability for the year 2013-14 is 5000
then it is shown as current liability in balance sheet and it should be reduced from profit before tax while calculating profits. (2013-14).
let suppose the liability for 2014-15 is 6000
then the carry forwarded liability of 5000 should be treated as opening deferred tax liability. 1000 should be reduced from profit before tax in the year 2014-15. i.e, (6000-5000).
6000 is shown in current year balance sheet as deferred tax liability.(2014-15).
if there is a deferred tax asset in the year 2014-15 of 4000. then entry is to be reversed. it should be reduced from current year profit and loss account.
deferred tax asset account dr 4000
to profit and loss account 4000
then the original entry of 6000 is to be posted actually.
profit and loss account a/c dr 6000
to deferred tax liability a/c 6000.
then there is a net effect of 2000 appears in profit and loss account indirectly.
then in balance sheeet 6000 to be shown as current liability and 4000 is to be shown as current asset.
the treatment made by you is correct but the treatment in balance sheet should be made properly. we cannot treat deferred tax asset and profit and loss account as same as u mentioned above. seperate accounts to be opened for both deferred tax asset and deferred tax liability for proper accounting tratment and understanding.
i hope you will understand. thank you
