New points to consider
While most assessees would provide information of relevant expenses and investments to their employer, you may have missed out on some. It may be the expenses and investments took place within the financial year but after you had provided documentary proofs to your employer. For example, a preventive health checkup may have been done on 15 March and you were not able to include bills as the last day to submit investment proof was 25 February. Such details that could not be included earlier, can be mentioned when you file your tax return. So, you should be aware of the new tax deduction rules.

In 2015 Budget, a few deduction limits were increased and some new ones were introduced. Tax deduction under section 80D of the Income-tax Act, 1961, against health insurance premium or preventive health check-ups was increased from R15,000 toR25,000. For senior citizens, this went up from R20,000 toR30,000. An additional deduction of R50,000 was introduced under section 80CCD for investments in National Pension System (NPS). This was over and above the standard limit of R1.5 lakh under section 80C.

The new ITR forms provide a specific space to claim the deduction under investment made in NPS. Take note of that space while filing tax returns if you have made this investment.

Also, whether filing on your own or with the help of a service provider, don't forget to claim tax collected at source (TCS), if any. TCS at the rate of 1% is collected from taxpayers when they purchase jewellery in cash exceeding R2 lakh in value. Credit of TCS can be claimed against the total tax . Credit for TCS can now be claimed via ITR-1, ITR-2 and ITR-2A. Earlier, it was not present in these forms

Complete the process
Filing the tax return itself does not mean the process is over. Don't forget to verify the form. If you have a digital signature, use that and submit the form. Even if you don't have a digital signature, you can verify the form online through a one-time password (OTP) generated using Aadhaar, Internet banking or even your ATM card. However, as of now, only State Bank of India offers OTP generation through ATM; more banks are expected to follow soon.

Once you e-verify the return, take a printout of the acknowledgement. The process is now complete. Save a copy for your record. If the return is not digitally signed, then generate the ITR-V Form, sign it and mail it to the income tax processing centre in Bengaluru, either by ordinary post or speed post, within 120 days of e-filing the return.

The process of tax filing has become easier over the years-online processes have been introduced; you no longer need to attach documents to the ITR; and many documents are available online. Now you have about a month's time to make use of these features and file your income tax return.
