All IRS representation runs through one document: Form 2848, the power of attorney. As a buyer, you should understand exactly what it does - because whether and when your representative files it is one of the most reliable tells in the industry.
What Changes When It Posts
Once the 2848 reaches the IRS's authorization file, the agency must deal with your representative on the covered matters: revenue officers call counsel, notices copy to counsel, conferences and negotiations route through counsel. You stop fielding IRS contact - and you stop generating the unguarded statements that become the record in your own case. For represented taxpayers, never speaking to the IRS at all is normal and contemplated by the procedure. It is frequently the single biggest practical benefit of hiring anyone.
What It Cannot Do, and How Scope Works
The 2848 transfers no money and no liability: your representative cannot touch your refunds, does not become responsible for your taxes, and gains no power over your property. It is revocable at any time in writing, and filing a new one for the same matters revokes the old unless you say otherwise - a quiet detail that matters when changing representatives. Scope is literal: the form covers exactly the tax types, forms, and years written on it, so competent practice grants what the case genuinely involves, including likely expansions, and nothing gratuitous.
The 8821 Tell
The form the 2848 gets confused with is the 8821 - a tax information authorization that lets someone receive your IRS information but represent you in nothing. Some national relief firms file only the 8821 while charging representation prices: they can read your mail, and they cannot negotiate, appear, or advocate. The check takes one call to the IRS or one look at your transcripts: which form sits on your account, and who filed it. If you are paying for representation right now, run that check this week. If the answer is an 8821 - or nothing - the free consultation here will tell you what your case actually needs.
