Tax Investigation Online
Most IRS problems show up as a notice, levy, or garnishment — after penalties have already grown. This portal is how you see what the IRS actually has on file before you commit to a resolution plan.
What this is
A file review, not a sales call
This is not a phone estimate and not automatic IRS representation. It is a structured look at your IRS records — filings, assessments, balances, and collection indicators — reviewed by Enrolled Agents.
Authorize Form 8821
Form 8821 is Tax Information Authorization. It lets our licensed team view IRS records you already have on file. It is not Form 2848 and does not let us speak to the IRS for you.
Review your IRS file
We retrieve transcripts through official IRS channels. Enrolled Agents review the file so you can see balances, missing returns, and collection risk in one place.
What the review looks at
IRS data lives in separate systems. The portal pulls those pieces together so you are not making decisions from a single notice or a partial transcript.
Unfiled or missing returns
Years the IRS shows as not filed, or returns that never posted correctly.
Assessed balances
Tax, penalties, and interest the IRS claims you owe — not a guess from a sales call.
Collection and levy risk
Whether the account looks quiet, or whether notices and enforcement are already in motion.
Deadlines that still matter
Collection statutes and other timelines that can change what options are still open.
Questions people ask before they start
- Is this the same as hiring Alter Tax to resolve my debt?
- No. Tax Investigation Online is an IRS file review. After the report, you can do nothing, handle it yourself, or ask us about resolution. Representation would require a separate agreement.
- Will Form 8821 trigger an audit or collections?
- No. Form 8821 only authorizes licensed professionals to view records that already exist. It does not give the IRS new information and does not change your account status.
- What if I already started a case?
- Go to ti.alter.tax/status and sign in with the email you used to start.
