10 years ago I had some special tax situation that the two tax preparers I consulted were not familiar with. They took the safe route in preparing the paperwork. So I called up the IRS support line and a specialist talked with me in detail about my situation and told me the proper way to do it and it saved me $5k in taxes.
Absolutely, but wait times have been increasing due to budget cuts. There’s an unhealthy fear/contempt of the IRS in the US. It’s one of the most important government agencies, and it should be treated as such and given the resources to serve the people better, instead of serving as a perpetual political punching bag.
Almost as if their job is to make sure that you pay taxes correctly... It really makes sense that they would want it to be correct as it is less potential work for them.
