It is an official IRS letter. I accidentally clicked the box on the 940 saying there was state credit reduction. Being that only the US Virgin Islands is the only credit reduction state, it was an obvious error. The tax was paid. But they are wasting taxpayer dollars and my time by asking me to send a Schedule A. I thought I would fax the reply, but wound up getting the Sex number response over the weekend. It is now changed to "We're sorry, the call can't be completed at this time".
