Draft the letter

Notice-specific arguments and the enclosure checklist, in ~20 seconds. Review, fill placeholders, mail certified.

Why people use it instead of ignoring the envelope

Frequently asked questions

What is TaxNoticeWiz?

A free toolkit for the moment an IRS envelope lands: plain-English explanations of every common notice — the real meaning, the deadline, the options — and an AI drafter that writes the response letter for your specific notice and situation.

Who is it for?

Regular taxpayers and small-business owners handling their own IRS mail — the people who don't have a tax attorney on retainer but can absolutely mail a well-organized response letter.

Is this tax advice?

No — it's reference information and self-help document preparation, like a smarter form template. You review every draft, fill in your own details privately, and decide what to send. Large amounts or fraud allegations belong with a CPA, EA or tax attorney.

Do you store my information?

The tools are designed around placeholders — [YOUR NAME], [SSN LAST 4] — so your identifiers never enter the system. Generation inputs are processed transiently and never stored.
