Help me to file income tax return for last 4 years

Hi All,

I am salary person, and due to some issue i am not able to file my tax return for last 4 Years, but i have paid all of my tax and I have all from-16 with me. The reason I was not able to file tax's as I was

traveling out of country most of time in month of March to August avery year. Right now also I am out of country and coming back on mid of August to India. I have filed tax return before 4 years for 2 years. I

am in JOB from last 7 years.

My 1st year salary was 80 Thousand P/A so i have not filed any return. (2005-2006)
My 2nd Year salary was 2.5 L P/A I have filed tax return for that. (2006-2007)
My 3rd Year salary was 3.5 L P/A I have filed tax return for that. (2007-2008)
My 4th Year salary was 5 L P/A and my company has deducted all tax and provided me Form-16 but I have not filed return. (2008-2009)
My 5th Year salary was 7.5 L P/A and my company has deducted all tax and provided me Form-16 but I have not filed return. (2009-2010)
My 6th Year salary was 9 L P/A and my company has deducted all tax and provided me Form-16 but I have not filed return. (2010-2011)
My 7th Year salary was 12 L P/A and my company has deducted all tax and provided me Form-16 but I have not filed return. (2011-2012)
My coming year salary will be 15 L P/A (2012-2013) and my company is providing salary after tax deduction. (2012-2013)

Note :- I have changed 5 companies in last 7 Years, but i have all document with me.

Please help me to get out this situations and I am sure after that I will file my tax return avery year as e-filing is very easy and fully online with digital signature now days.
