Submission of documents and investment proofs generally starts in December because the readjusted amount of tax payable may be deducted at source (TDS) from the salary payable for January, February and March. However, some companies provide more time for submission of the documents to allow employees make the investments as planned. But March is the last month of the financial year and hence it's last chance for employees to submit the documents to save the tax outgo in form of TDS.
