The IRS is actually quite helpful, you just have to ask. For example you can request that they give you all the information they have on you. This can make filing or amending old returns significantly easier.

And in my experience at least, their customer service people are courteous and genuinely helpful. It's nothing at all like the standard substandard DMV experience.

Another cool thing is they have an absolutely fantastic record for providing real opportunities (not just busywork) to disabled persons.

In many other countries they do act like that.

Ha, surprised, I've seen more prowess in seeking high difficulty tax evasion from small people than help so far.
