Frequently asked

Is this legal or tax advice?

No. IRS Shield provides analysis and information based on published IRS rules and notice procedures. For complex situations — Tax Court petitions, criminal referrals, large Offers in Compromise, or anything above $50,000 — you should consult a tax attorney or enrolled agent. We tell you clearly when that threshold is reached.

Which IRS notices does this cover?

All 47 common IRS notice types: CP2000 (underreporter), CP14 (balance due), LT11 / CP90 (levy warnings), CP501/502/503 (demand series), Letter 531 (90-day letter), CP2501, CP11/CP12 (math error), Letter 1058, CP71C, Letter 3219, audit letters, and more. If you receive a notice we don't recognize, we flag it immediately.

How long does the analysis take?

About 60-90 seconds after you paste your notice text. The result is structured: notice type in large text, urgency countdown, plain-English explanation, complete response letter, and documentation checklist.

What is First Time Abatement and do I qualify?

First Time Abatement (FTA) under IRM 20.1.1.3.6.1 can eliminate 100% of failure-to-file and failure-to-pay penalties if you have a clean compliance history (no penalties in the prior 3 years). IRS Shield checks your notice for FTA eligibility automatically and includes the abatement request in your response letter if applicable.

Is IRS Shield worth $249/mo?

An enrolled agent or CPA charges $400–$800 to analyze a single IRS notice and write a response. At $249/mo you can handle multiple notices per year, track deadlines, and avoid the $550+ per-letter alternative.

What if I don't get results?

If the IRS does not accept your response on a clearly identified issue (misapplied code, FTA-eligible penalty), we flag the next escalation path — appeals, Tax Court, or Taxpayer Advocate Service — so you know exactly where to go next.
