Should i pay income tax?

Hello everybody,

I am Pandian. During the financial year 2012-13, I worked for two companies. Upto September 2012, I worked for one company and the rest of the financial year I worked for another company. Both two companies did not do any TDS for me. Now I just calulate my today income, it seems 3.3 L. Moreover, I have invested 70k on tax saving fixed deposit. FD was the only document I had submitted to my employer. I also have 10+K medical bills and some tax saving documents that I did not submit to anyone.

Here is the queries I have.

1.) Can I use 10+k medical bills when I file IT return?

2.) As my total income is greater than limited, Should I pay self assesment tax?

Please help me out.
