2.1. Pursuant to Idaho Code § 63-3045(1)(a), Petitioner [TAXPAYER NAME] ("Taxpayer") files this written protest and Petition for Redetermination contesting the Notice of Deficiency Determination ("Notice") issued by the Idaho State Tax Commission ("Commission") on [DATE NOTICE MAILED], asserting an alleged income tax deficiency of $[AMOUNT] plus interest of $[AMOUNT] and penalties of $[AMOUNT] for the tax year(s) ending [DATE(S)].
2.2. The Notice asserts adjustments based on [BRIEF DESCRIPTION OF COMMISSION'S ASSERTED BASIS — e.g., disallowed business deductions, federal RAR adjustments, residency redetermination, addback of credits].
2.3. Taxpayer disputes the entirety of the proposed deficiency on the grounds set forth in Sections 5 through 7, infra.
3. TIMELINESS STATEMENT
3.1. The Notice was mailed by the Commission on [__/__/____].
3.2. The sixty-three (63) day protest period prescribed by Idaho Code § 63-3045(1)(a) expires on [__/__/____].
3.3. This Protest is filed and served on [__/__/____], which is on or before the sixty-third (63rd) day following the mailing date and is therefore timely.
4. STATEMENT OF FACTS
4.1. Taxpayer is [an individual resident of / a non-resident with Idaho-source income from / a corporation registered to do business in] Idaho.
4.2. Taxpayer timely filed Idaho Form [40 / 43 / 41 / 41S / 65 / 66] for tax year(s) [YEAR] on [__/__/____], reporting [ADJUSTED GROSS INCOME / IDAHO TAXABLE INCOME] of $[AMOUNT] and Idaho income tax of $[AMOUNT].
4.3. On [__/__/____], the Commission [issued an audit engagement letter / opened a desk examination / received a federal RAR from the IRS] concerning Taxpayer's return.
4.4. During the examination, Taxpayer [describe cooperation: produced records, responded to Information Document Requests (IDRs), attended conferences, etc.].
4.5. The Commission issued the Notice of Deficiency Determination on [__/__/____] asserting the adjustments described in paragraph 2.2.
4.6. Taxpayer disagrees with the proposed adjustments for the reasons set forth herein and supports its position with the records, schedules, and authorities cited in the attached exhibits.
5. GROUNDS FOR PROTEST
5.1. Adjustment 1 — [DESCRIBE ADJUSTMENT, e.g., Disallowed Schedule C Expenses].
(a) The Commission's adjustment is incorrect because [FACTUAL EXPLANATION].
(b) Idaho conforms to the Internal Revenue Code per Idaho Code § 63-3004 with limited modifications, and the deduction is properly allowable under I.R.C. § [CITATION] as reflected on Taxpayer's accepted federal return.
(c) Documentation supporting the deduction is attached as Exhibit A.
5.2. Adjustment 2 — [DESCRIBE ADJUSTMENT].
(a) The Commission misapplied Idaho Code § [CITATION] because [LEGAL EXPLANATION].
(b) See [CITE IDAHO CASE OR ADMINISTRATIVE DECISION, e.g., Albertson's, Inc. v. Idaho State Tax Comm'n, 106 Idaho 810 (1984)].
5.3. Residency / Source Issue (if applicable). Taxpayer [was a non-resident throughout the year / changed domicile on [DATE] / had no Idaho-source income] under Idaho Code § 63-3013 and IDAPA 35.01.01.030, and the Commission's residency determination is contrary to the factual record.
5.4. Apportionment Issue (if applicable). The Commission's apportionment of business income is inconsistent with Idaho's three-factor formula under Idaho Code § 63-3027 and the Multistate Tax Compact provisions adopted in Idaho.
5.5. Federal Conformity. To the extent the Commission's adjustments conflict with the federal treatment accepted by the IRS (or are based on a federal RAR not yet final), Idaho's rolling conformity to the I.R.C. requires recognition of the federal result.
6. STATUTE OF LIMITATIONS DEFENSE
6.1. Pursuant to Idaho Code § 63-3068(a), the Commission must issue a Notice of Deficiency within three (3) years from either the due date of the return (without regard to extensions) or the date the return was filed, whichever is later.
6.2. Taxpayer's return for tax year [YEAR] was due on [__/__/____] and was filed on [__/__/____].
6.3. The three-year limitations period therefore expired on [__/__/____].
6.4. The Notice was mailed on [__/__/____], which [is / is not] beyond the limitations period. To the extent the Notice asserts a deficiency for any closed period, that portion of the assessment is barred and must be abated.
6.5. None of the statutory exceptions extending the limitations period apply because [no fraud, no false return with intent to evade, no failure to file, no consent to extend (Form 870), and no substantial omission triggering the six-year period under § 63-3068(b)].
7. PENALTY ABATEMENT REQUEST
7.1. Taxpayer requests abatement of all penalties asserted in the Notice on grounds of reasonable cause and absence of willful neglect under Idaho Code § 63-3046 and § 63-3033, consistent with the Idaho Taxpayer Bill of Rights (Idaho Code § 63-4001 et seq.).
7.2. Reasonable cause exists because [DESCRIBE — reliance on competent professional advice, serious illness, casualty, records destroyed, ambiguity in Idaho law, good-faith reporting position consistent with federal treatment].
7.3. Taxpayer has a history of timely compliance with Idaho tax obligations and has cooperated in good faith throughout the examination.
8. REQUEST FOR INFORMAL HEARING
8.1. Pursuant to Idaho Code § 63-3045(3) and IDAPA 35.02.01, Taxpayer requests an informal hearing before the Commission's Appeals Unit to present evidence and argument prior to issuance of a Final Decision.
8.2. Taxpayer requests that the hearing be held: ☐ in person at the Commission's Boise office; ☐ by telephone; ☐ by videoconference.
8.3. Taxpayer's preferred dates: [DATES].
8.4. Taxpayer ☐ will / ☐ will not be represented by counsel or authorized representative. If represented, a Power of Attorney (Form ID-POA) is attached as Exhibit POA.
9. RELIEF REQUESTED
WHEREFORE, Taxpayer respectfully requests that the Commission:
- A. Cancel the Notice of Deficiency Determination in its entirety; or, in the alternative,
- B. Redetermine the deficiency to reflect the correct Idaho income tax liability of $[AMOUNT] for the periods at issue;
- C. Abate all asserted penalties for reasonable cause;

- E. Apply Idaho Code § 63-3045(c)'s restrictions on assessment and collection while appeal rights remain pending;
- F. Schedule an informal hearing as requested in Section 8; and
- G. Grant such further relief as the Commission deems just and proper.
10. RESERVATION OF APPEAL RIGHTS
10.1. Taxpayer expressly reserves all rights to appeal any adverse Final Decision of the Commission, including:
(a) Appeal to the Idaho Board of Tax Appeals under Idaho Code § 63-3049 within ninety-one (91) days after receipt of the Final Decision, after providing the required 20% cash deposit or acceptable security;
(b) A complaint in the Idaho District Court for [ADA / OTHER] County under Idaho Code § 63-3049 within the same ninety-one (91) days after receipt, after providing the required 20% cash deposit or acceptable security;
(c) Further appeal to District Court from any adverse Board of Tax Appeals decision under Idaho Code § 63-3812, taken and perfected pursuant to Idaho R. Civ. P. 84, ordinarily within twenty-eight (28) days after the BTA action is ripe for review; and
(d) Appeal to the Idaho Supreme Court from any adverse District Court judgment.

13. IDAHO PRACTICE NOTES
- 63-day protest deadline. Idaho's protest deadline under Idaho Code § 63-3045(1)(a) is sixty-three (63) days, not the more common 30, 60, or 90 days. The deadline runs from the date the Notice of Deficiency Determination is sent, not received. Calendar carefully and file via traceable means.
- Reduced 30-day window. Certain audit categories (e.g., Notices of Determination relating to permit revocations and some withholding matters) carry a 30-day protest window under separate provisions; verify the controlling statute on the face of the Notice.
- Two-track post-decision review. After receiving a Final Decision under Idaho Code § 63-3045B, an individual income-tax taxpayer may appeal de novo to the BTA or file a complaint in District Court under § 63-3049, in either case within 91 days. Section 63-3049(b) requires a 20% cash deposit or acceptable substitute security before either route.
- Board of Tax Appeals procedure. The Board sits as a de novo administrative tribunal. Hearings are recorded; the Board may receive evidence, hear testimony, and issue written decisions. Further appeal to District Court is governed by Idaho Code § 63-3812 and current Idaho R. Civ. P. 84, ordinarily requiring filing within 28 days after the BTA action is ripe for review.
- Statute of limitations. Current Idaho Code § 63-3068(a) generally requires a notice of deficiency within 3 years from the later of the original due date, without regard to extensions, or the filing date. The current statute permits action at any time for fraud, a false return with intent to evade, willful evasion, or non-filing, subject to the reasonable-belief exception in subsection (d); it does not contain the former template's 25%-omission extension. Federal adjustments follow the current special provisions in §§ 63-3068 through 63-3070.
- Collection and protest-period interest. Idaho Code § 63-3045(c) restricts assessment and collection until appeal rights become final. For a NODD subject to a perfected protest, current § 63-3045(7)(a) provides that deficiency interest does not accrue from issuance of the NODD through the Tax Commission's final determination following disposition of the protest.
- Power of attorney. Use Form ID-POA to authorize a representative. The Commission generally accepts IRS Form 2848 if it specifically lists Idaho tax matters.
- Idaho Taxpayer Bill of Rights. Idaho Code § 63-4001 et seq. guarantees rights to a clear explanation of procedures, recording of interviews, designation of representatives, and limitations on workplace contact. Cite these rights in cases of perceived overreach.
- Records retention. Maintain records for the longer of (i) the federal retention period or (ii) the Idaho three-year limitations period plus any extensions or open RAR years.

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.
