There are 2 things everyone should know.
1- Anyone can take the irs to tax court for a fee of $60. You do not need an accountant or a lawyer to be present with you. If you have all the documentation to prove your right you can go it alone.
Of course for more complex issues an accountant or lawyer can go with you.
Also, you have a small amount of time to go the court route. If you miss the deadline the tax advocate is your best, and probably, only hope.
Did I mention the service of the tax advocate is free?
2- If your having long term issues with the irs the tax advocate is your best bet to get it fixed.
If you haven't gotten it yet. IF YOUR HAVING TROUBLE WITH THE IRS THE TAX ADVOCATE IS PROBABLY YOUR BEST BET TO GET IT FIXED.
