8. OREGON PRACTICE NOTES
- No general sales tax. Oregon is one of five states (with AK, DE, MT, NH) without a general state retail sales tax. Audit practice is therefore concentrated in income, corporate excise, withholding, the Corporate Activity Tax (CAT), the Statewide Transit Tax, and the Vehicle Privilege/Use Tax. Sales-tax-style "Wayfair" nexus issues do not arise for Oregon, but economic nexus issues are very much alive for income/excise and CAT.
- Statute of limitations. General three-year period from filing under ORS 314.410(1). Five years for substantial (25% +) omissions of income; unlimited for false/fraudulent returns or non-filers (ORS 314.425). Carefully diary the limitations expiration; signed waivers (Form OR-1180-WAIVER) extend the period only as written.
- Federal "piggyback." ORS 305.305 obligates taxpayers to notify the Department of any federal RAR within a fixed window (generally 90 days from finality). The Department then may assess based on the federal change. Engaging the federal proceeding is often the most efficient defense.
- Confidentiality. Returns and audit information are confidential under ORS 314.835 and ORS 305.380–305.404. Unauthorized disclosure is a Class C felony under ORS 314.991.
- Recording rights. Taxpayer may record any audit interview after 24-hour notice to the auditor under ORS 305.880(2). The Department may also record but must inform taxpayer.
- Conference vs. appeal. A Department conference under ORS 305.265 is an informal, internal review. It does not start the 90-day Tax Court appeal clock — the Conference Decision (or Notice of Assessment if no objection) does.
- Compromise authority. The Director may compromise any tax liability under ORS 305.155 in cases of doubt as to liability, doubt as to collectability, or to promote effective tax administration. Compromise offers may be made before or during examination.
- Oregon Tax Court Article VII court. Any judicial appeal proceeds exclusively through the Oregon Tax Court (Magistrate Division → Regular Division → Oregon Supreme Court). See companion template
state_income_tax_protest.md. - Penalties. Watch for negligence (ORS 305.265(13)), substantial-understatement (ORS 314.402), failure-to-file/pay (ORS 314.400), and 100% civil fraud (ORS 314.402(1)(b)). Reasonable cause / good-faith defenses parallel federal § 6664 standards in practice.
- CAT-specific note. The Corporate Activity Tax (ORS Ch. 317A) is administered under general ORS Chapters 305 and 314 procedures by virtue of ORS 317A.149. Audit responses for CAT track the format above; substitute CAT-specific authorities (ORS 317A.116, 317A.122, 317A.125, 317A.128).

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.
