Bad UX for e-filing taxes

This weekend, like a good American, I filed my taxes. I decided to do it online, and it wasn't too bad; it only took about a half hour. I submitted and went on my merry way.

Immediately after, I got an email saying my filing had been rejected, with a somewhat cryptic error message:

Issue : Business Rule X0000-005 - The XML data has failed schema validation. cvc-complex-type.2.4.a. Invalid content was found starting with element 'EmployeeUSAddress'. One of '{"http://www.irs.gov/efile":ControlNumber, "http://www.irs.gov/efile":EmployeeName}' is expected.

The following information may help you determine the form at issue: Field/Xpath: /efile:Return[1]/efile:ReturnData[1]/efile:IRSW2[1]/efile:EmployeeUSAddress[1]

I figured the server was having trouble and decided to try again later.

This morning, I decided to try again. I noticed a link from the site that said Fixing Your Rejection[1]. Clicking on it, I was greeted with a 38-page PDF that started with a description of how to search for my error message within the document.

I know that government systems aren't terribly sophisticated (unless they're tracking people's activity online that is) but I personally think it's ridiculous to expect anyone to know that this is expected behavior. Rather than type up their PDF, they should have put all this information into a database and used that to generate the email. If this were a company's site, the bounce rate would be tremendous.

Do you all think this is useable as-is, or that this is an unacceptable UX?
