You need to respond to the letter.
Pull together your information for that year, including all your sources of income.
Make a list and add up the total income. Verify that your income and source of income meets the following criteria
If
your income is below the minimum filing requirements for the year and
you did not earn income from a job or self-employment, you do not need
to file a tax return. The minimum filing requirements for taxpayers
under 65 and not blind in 2011 are:
Single $ 9,500
Married Filing Jointly $19,000
Married Filing Separately $ 3,700
Head of Household $12,200
Qualifying Widow(er) $15,300
If you are self-employed you must file if you earned $400 or more.
Respond to IRS with the list and total income and explain you meet the standards set forth and were not required to file.
Keep the originals and mail copies to IRS...I suggest mailing return return receipt required.
