Response to Intimation 143(1)

Hi,

In 2007, I prepared my ITR-1 and gave it to my office person to submit. He did so on 27 July 07 but lost the acknowledgment. On asking him to give me an acknowledgment, he filed it again on 27 Sep 07 and gave me the acknowledgment.

In Feb 09, I got an intimation under 143(1) to pay 10k tax. I did so online and got the acknowledgment. This intimation referred to my Sep 07 filing. In Mar I got an intimation under 143(1) to pay 10k - this referred to my July 07 filing.

I have the acknowledgment of tax that I paid in response to the first intimation.

My question:
1. Do I need to file any return for the same?
2. How do I know that my taxes are ok for that year? Can I check it online?

Regards,
Jeev
