My friend is getting LTA @1250 pm, is this wholly exempted or taxable. Pls let me know the calculation of exemption and as he has already paid 40K as IT for march 08 as deducted by his employer. Now while preparing his computation, he found that tax to be paid is 15K more. So if he files IT as on 31st july 08 within duedate and pays 15K also, then also is he liable to pay any interest or penalty. pls suggest
