What is the treatment if preliminary expenses and preoperative expenses under accounting and income tax? ?

So far as I know, under accounting, both are treated as miscellaneous expenditure till operations are started and once operations are started, preliminary expenses are written off in p/l accounts 1/5 that each year

And preoperative expenses are allocated to fixed assets irrespective of whether or not these preoperative expenses are related to those fixed assets and depreciation is charged on that.

Am I correct? ?

Please suggest.
