You can file your return of income for claiming refund of taxes even if your income does not exceed the exemption limit due to TDS. Your employer, Banks & financial institutions deduct TDS sometimes more than your tax liability which you can easily claim by filing your Income tax return. This return for claiming the refund of excess taxes paid can be filed within a period of two years from the end of the financial year for which the claim of refund is related.
Filing of tax return these days have become very easy and in many cases even free through several e-filing portals such as H&R Block which also provides assistance in case you are stuck somewhere. All you need to do is to check your tax liability using an Income tax calculator and if you have paid more than what you are liable to pay then file your return online to claim the refund of excess tax paid.
