I am trying to figure out my IRA basis and I need game plan. Here is my situation:

1982 through 1987 – I claimed a deductible IRA, so no basis for these years.

1988 through 1991 – I did not claim a deductible IRA, however I [u]did[/u] contribute to a nondeductible IRAs. These years will have basis.

In 1992 I submitted my first 8606 form. On the form I incorrectly listed the basis for all prior years as zero. I do not have the documentation to refute the incorrect basis. I will just have to pay more in tax. My main problem is that I also do not know which year(s) the IRA(s) were contributed to in 1988 – 1991. I rolled some IRA CD’s into mutual funds and I have some records of this, based on the total it must be for more than one year.

In 1995 I did contribute to a nondeductible IRA and I did not file form 8606 ( I believe it was do to a different tax package not picking it up). This means that a $2000 basis error has cascaded up through the years making them all wrong.

I recognize that I can summit updated naked 8606 (without filing an amended 1040) for each year, but I have no idea what the basis is for a number of years. Will the IRS provide a taxpayer the basis information that they have on file? Knowing that information would be very helpful. To send in a “corrected” 8606 form that does not match the IRS data, does not seem like a good idea. Any suggestions? All help is greatly appreciated.
