Accounting of prior year expenses

Hi,

I would like to know the accounting entry for prior period expenses. Say we had made provision for some professional fees for one lac in FY 13-14 (short provided) and after completion of audits for FY 13-14 the actual expenses incurred was one lac fifty thousand. Can we book short provided expenses (fifty thousand) in current year (FY 14-15). Will this expenses be allowed in income tax during computation of income. Note that the services were received and bill was raised in previous year but the same was short provided due to some reason.

Thanks
