<prompt> Human: First off, this is not for me personally but for someone very close to me. I am helping them put together a path forward to get out from under many years of unpaid taxes due to drug and alcohol addiction.Situation:- Never filed taxes 30 years- Havent been paid by anyone filing taxes. Worked under the table in construction for all of this time.- Recently contacted by IRS via phone and have made some small payments in the thousands.- Still working under the table to make a living to avoid the IRS, vicious cycle.What professionals could be contacted and hired to help get out from under the debt? Is it wise to use a company like HR block or is a private CPAs tax professional better suited? What is the typical cost of these services? After initial contact is made with tax professionals, is there legal obligation by either party to report to IRS? The goal is to get set up on a path to settle the debt with the IRS over a payment schedule, but also to relieve some of the stress of starting this process. Example and personal stories are welcome!Thanks for the help!  <response>: IRS would never call to collect. They will always send a letter.The call is possibly a scam. I suggest you confirm if the call is legitimate.Some literature:
