You can definitely file your income tax return on your own. Income tax e filing portal is very user friendly where anyone with basic knowledge of income tax can file their return.
But I will recommend you to file the income tax return with the proper advice of a Chartered accountant. I have many clients who are willing to file income tax return just to get maximum refund of TDS deducted by employer or banks.
Chartered accountant or any income tax advisors will advise them to avail various exemptions. My many clients doesn’t know the provisions or rules for claiming leave travel allowance or house rent allowance or voluntary contribution in national pension schemes u/s 80CCD(1B) or other similar provisions. And hence end up paying more taxes.
Professional guidance is very important in case of business clients where proper tax planning saves thousands of rupees of taxes.
I would recommend you all (where tax audit is not applicable) to file their income tax return before 31st July to avoid penalty of Rs. 1000 in case of taxable income upto Rs. 5 lakhs and Rs. 5000 for other cases. Filing of income tax return not only benefits us but also to the government in analysing various economic decision.
