The Taxpayer Advocate Service (TAS) has two main phone numbers.
877-ASK-TAS1 (established in 2004)
877-777-4778 (NTA toll-free line, established in 1998)
The NTA toll-free line is the more prominent number on the TAS website. It is the number found under the “contact us” link. And this is the same number listed on the IRS website. However, the primary difference between these two numbers may surprise you. ASK-TAS1 is staffed by TAS personnel, but the NTA toll-free line is actually staffed by IRS customer service personnel! See the latest TIGTA report for more information. These representatives are charged with vetting out the cases that they believe will “qualify” for TAS help.
TAS describes itself as an “independent organization within the IRS” — really an oxymoron, don’t you think? Tax professionals have long questioned their independence. When you call TAS, you are literally talking with the IRS (unless you dial the right number). I do not recommend calling TAS for help with your tax problems. For high-quality tax relief, it is important to select an experienced tax attorney that can give objective, unbiased attention to your tax matter.
