Just out of curiosity and to learn more, for past few years, I have been calculating tax, making whatever extra payment other than TDS online, filling return forms and submitting tax return myself. I am always excited to try new ways government implements.
I registered myself 3 years back to view tax credits paid by my employer as TDS. You can also register here : Check you tax credits. You can also download Form 26 AS here and see how much tax has been deposited on your name from your employer or any other firm.
You can view it to verify if the tax payments made by you or TDS deducted from salary or interest etc are correctly reported to the income tax department. You can also check income tax refund from previous year in the same form.
