If tax is adequately deducted by your employer on the salary paid to you, then you will most likely not be needed to pay more tax at the time of filing the return.The only circumstance where this might be likely is a situation where you declare additional income from other sources such as savings bank interest above the deductible limit, or fixed deposit interest or capital gains.Sometimes if you change jobs in a year, there is mismatch on TDS deductible on your salary from both employers put together usually due to proper protocol not being followed or lack of communication of your past salary to the new employer.Hope this helps.
