My previous employer sent out a second W-2 (not corrected just additional), stating that due to an administrative error Stock Option Exercises were never reported on the 2011 W-2. I already filed my return. They did not send out this letter with the additional W-2 until March 26th, which I received on April 9th.
What should I do? If I file an amended return is there any way to make them pay the cost for their screw up?
1040X is a replacement return.
You can prepare a 1040X with new W-2 and include a copy of the earlier (defective) return and earlier (defective) W-2. It would be optional to highlight the replacement W-2 or by cover letter stating what is enclosed.
If you include payment and prove the date of submission before April 15, you would hopefully get ahead of the machinery that might try to provide some deficiency calculation.
Paying for the error is up to your employer. This is difficult as time spent might be a few changes to your forms, reprinting and re-filing for some people. Others may have extensive other holdings and a re-do on their tax filings might cost over $1000. (very uneven effect among employees)

You might politely request your employer pay the cost of amending your return. Unfortunately, the new W-2 should follow the W-4 you submitted to determine the level of withholding, and you are ultimately responsible for additional tax due (if any). Moreover, it does not seem that there would be any additional penalties or interest that you would not already be responsible for (i.e., if you under-witheld).
