I. Jurisdictional Statement

This Petition is filed within 60 days of the Taxpayer's receipt of the Notice and is therefore timely under Wis. Stat. § 71.88(1)(a) [or § 77.59(6)]. Receipt occurred on [__/__/____]. The 60-day period expires on [__/__/____].

Tax Type [____________________]
Periods [____________________]
Notice Date [__/__/____]
Date Notice Received [__/__/____]

III. Issues Presented

a. Whether [Issue 1].

b. Whether [Issue 2].

c. Whether penalties imposed under Wis. Stat. §§ 71.83, 71.84, or 77.60 should be abated.

IV. Statement of Facts

[Numbered factual allegations.]

V. Argument

A. The Assessment Is Wrong as a Matter of Law

[Develop legal argument citing Wis. Stat. ch. 71/77, Wis. Admin. Code Tax 2/11, DOR Publications and Tax Bulletins, and WTAC / Wisconsin court decisions (e.g., General Casualty Co. v. DOR; Deere & Co. v. DOR).]

B. The Assessment Is Not Supported by the Facts

[Argue factual record.]

C. Penalties Should Be Abated for Good Cause

Under Wis. Stat. § 71.83(1)(a) negligence penalties and § 71.83(2)(a) intent-to-defeat penalties are discretionary. Reasonable cause exists based on: [reliance on professional advice; ambiguity; ordinary business care; etc.]

D. Statute-of-Limitations Defense

The portion of the assessment relating to [period] is barred by the 4-year SOL of Wis. Stat. § 71.77(2). DOR's reliance on extended SOL provisions is misplaced because [no fraud; no intent to defeat; return was filed].

E. Burden-Shift Reservation (§ 71.77(8))

The Petitioner notes that, for any assessment relating to a period more than 6 years prior to the year of assessment, the burden of proof shifts to DOR under Wis. Stat. § 71.77(8).

VI. Relief Requested

WHEREFORE, the Petitioner respectfully requests that the Department:

a. Cancel the Notice of Additional Assessment in full;
b. Alternatively, redetermine the assessment to $[_____];
c. Abate all penalties;
d. Recompute interest accordingly; and
e. Issue refund of any amount paid plus statutory interest under Wis. Stat. § 71.82.

VII. Hearing Request

The Petitioner ☐ requests a conference with the Resolution Unit ☐ consents to disposition on the written record.

VIII. Verification

I declare under penalty of perjury under the laws of the State of Wisconsin that the foregoing is true and correct.

About This Template

Tax law covers the paperwork that documents income, deductions, disputes, and settlements with the IRS and state tax authorities. Protests, offers in compromise, installment agreement requests, and appeals each have their own forms, supporting documentation, and strict deadlines. Well-prepared tax correspondence is often the difference between a negotiated resolution and an enforcement action with levies, liens, or penalties.

Important Notice

This template is provided for informational purposes. It is not legal advice. We recommend having an attorney review any legal document before signing, especially for high-value or complex matters.
