I had a situation last year where the IRS sent me a notice that I owed something like $20,000 in taxes from a single 1099 they claimed I did not file. In fact, they had missed a decimal point on the 1099 and read something like $75,000 rather than the $750.00 that was on the 1099. After re-sending them copies of the 1099 and all the data I had on what I filed, they responded saying the matter was settled and apologized for the inconvenience, but I'm still bothered by the fact that had that decimal place error been my own fault, I would have been fined $3,000 (according to the documents they sent) but when they make the mistake they just send a form letter apology.
