12. IDAHO PRACTICE NOTES

• Income-tax assessment SOL. Current Idaho Code § 63-3068(a) generally sets a 3-year notice-of-deficiency period measured from the later of the return's original due date, without regard to extensions, or the filing date. Current subsections (c) and (d) allow action at any time for fraud, a false return with intent to evade, willful evasion, or non-filing, subject to the reasonable-belief exception stated in subsection (d). The current statute does not contain the former template's 25%-omission extension.
• Sales/use tax SOL. Idaho Code § 63-3633 imposes a 3-year assessment period (7 years for non-filed returns; unlimited for fraud) and a 6-year collection period after assessment. Sales-tax records must be retained at least 4 years under § 63-3625.
• Federal RAR reporting. Idaho Code § 63-3069 requires taxpayers to report federal adjustments to Idaho. Failure to report opens a separate limitations window for Idaho assessment based on the federal change. Coordinate Idaho audit response timing with federal proceedings.
• Conformity to I.R.C. Idaho conforms (rolling) to the Internal Revenue Code under Idaho Code § 63-3004 with limited statutory modifications. Federal audit positions, regulations, and case law are persuasive on Idaho conforming provisions.
• Audit techniques. Idaho auditors commonly use markup analysis, bank-deposit analysis, ratio analysis, and net-worth methods, particularly for cash-intensive businesses. Be prepared to reconcile bank deposits to reported gross receipts and to explain non-taxable deposits (loans, transfers, gifts).
• Privilege. Idaho recognizes the attorney-client privilege; the federally authorized tax practitioner privilege under I.R.C. § 7525 is generally limited to non-criminal federal tax matters but may apply by analogy. Engage counsel early for sensitive or potentially fraud-adjacent issues.
• Resale and exemption certificates. For sales-tax audits, the burden is on the seller to support claimed exemptions with valid Form ST-101 certificates. Missing or defective certificates can be cured if the seller obtains a valid certificate before the audit closes; "good faith" acceptance defenses are limited.
• Voluntary disclosure. Taxpayers with un-filed returns may consider the Commission's voluntary disclosure program, which generally limits look-back to 3-4 years and waives certain penalties. Voluntary disclosure cannot be initiated after audit contact.
• Settlement authority. Idaho's Appeals Unit has authority to settle cases based on hazards of litigation. The audit division generally does not. Reserve substantive concessions for the Appeals stage where appropriate.
• Records destruction. Do not destroy records during an open audit. Spoliation can give rise to adverse inferences, fraud penalties, and criminal exposure.
