5. POSITION STATEMENT ON DISPUTED ISSUES

Position Statement of [TAXPAYER NAME] — Audit of [PERIOD]

5.1. Issue One — [Describe issue, e.g., "Taxability of Software-as-a-Service Subscriptions"].

• Auditor's position: [summarize].
• Taxpayer's position: [summarize].
• Supporting authority: Wyo. Stat. § 39-15-103(a)(i)(D); DOR Rules Ch. 2 § [__]; [CASE NAME], [YEAR] WY [__].
• Quantitative impact: $[AMOUNT].

5.2. Issue Two — [Describe issue, e.g., "Resale Certificates from [VENDOR]"].

• Auditor's position: [summarize].
• Taxpayer's position: Certificates were obtained in good faith and are valid under Wyo. Stat. § 39-15-105(a)(iii) and DOR Rules Ch. 2 § [__].
• Quantitative impact: $[AMOUNT].

5.3. Issue Three — [Describe issue, e.g., "Use Tax on Out-of-State Equipment Purchases"].

• Auditor's position: [summarize].
• Taxpayer's position: [summarize, including any credit for tax paid to another state under Wyo. Stat. § 39-16-105(a)(viii)].
• Quantitative impact: $[AMOUNT].

5.4. Aggregate disputed amount: $[TOTAL] (tax) + $[INTEREST] + $[PENALTY].

6. STATUTE OF LIMITATIONS DEFENSE

6.1. Three-year look-back. Under Wyo. Stat. § 39-15-108(c)(ii) and § 39-15-110, the audit period "shall not exceed three (3) years immediately preceding the reporting period when the audit is engaged."

6.2. Engagement date. The Notice of Engagement is dated [DATE]. The earliest reporting period subject to assessment is therefore [DATE − 3 YEARS].

6.3. Periods outside the three-year window. Any deficiency proposed for periods before [DATE − 3 YEARS] is barred unless the Department demonstrates by competent evidence (i) a violation of Title 39 or (ii) gross negligence in reporting or remitting taxes.

6.4. Refund claims. Conversely, no credit or refund is allowed after three (3) years from the date of overpayment. Wyo. Stat. § 39-15-109(c)(ii). Receipt of a written refund claim by DOR tolls the limitations period.

6.5. One-year audit-completion clock. The audit must be completed within one (1) year of the engagement notice. Wyo. Stat. § 39-15-108(c)(ii). If the Department fails to issue final findings by [DATE + 1 YEAR], Taxpayer reserves the right to seek dismissal or limitation of the assessment.

7. WYOMING TAXPAYER BILL OF RIGHTS — INVOCATIONS

Pursuant to Wyo. Stat. § 39-11-102, Taxpayer expressly invokes the following enumerated rights, each of which is binding on the Wyoming Department of Revenue and Department of Audit:

• ☐ (a) Information services. Right to obtain copies of public records and plain-language explanations of any billing, assessment, or audit procedure.
• ☐ (b) Impartial administration. Right to assurance that no auditor is compensated, promoted, or rewarded based on the amount of assessments or collections.
• ☐ (c) Confidentiality. Right that records protected by statute (e.g., § 39-15-107(b)(viii)) are not disclosed.
• ☐ (d) Penalty / interest abatement on reliance. If tax has accrued penalty or interest because Taxpayer relied on erroneous written information from the State, such penalty and interest shall be abated when the facts disclosed were substantially correct.
• ☐ (e) Installment payment plan. Right to request an installment agreement when lump-sum payment would cause severe hardship.
• ☐ (f) Plain-language notices. Right to assessment notices that describe in plain terms the basis of the assessment and the procedures for appeal.

8. CLOSING CONFERENCE AND AUDIT FINDINGS RESPONSE

8.1. Closing conference request. Pursuant to Wyo. Department of Audit policy and Wyo. Stat. § 39-11-102(f), Taxpayer requests a closing conference at least ten (10) business days before the issuance of any final audit report, in order to review proposed adjustments, exchange documentation, and narrow disputed issues.

8.2. Written response to draft findings. Within [14 / 21] days of receipt of the draft audit report, Taxpayer will submit a written response addressing each adjustment, signed by counsel.

8.3. Acceptance / partial agreement / full disagreement. Taxpayer's response will indicate, line-by-line, whether each adjustment is:

• ☐ Accepted;
• ☐ Accepted in part / disputed in part (with quantification); or
• ☐ Disputed in full (with statutory basis preserved for appeal).

9. RESERVATION OF APPEAL RIGHTS

9.1. By participating in this audit and producing documents, Taxpayer does not waive — and expressly reserves — all rights to:

• File a written objection and request a hearing under Wyo. Stat. § 16-3-107;
• Appeal any final DOR determination to the Wyoming State Board of Equalization within thirty (30) days under Wyo. Stat. § 39-15-109(b)(iv) (sales), § 39-16-109(b)(iv) (use), or the analogous severance section;
• Seek judicial review in the appropriate Wyoming District Court under Wyo. Stat. § 16-3-114; and
• Pursue a refund claim under Wyo. Stat. § 39-15-109.

11. WYOMING PRACTICE NOTES

• Two agencies, one audit. Wyoming uniquely splits state-tax administration: the Department of Audit conducts the audit; the Department of Revenue issues the assessment and answers the appeal. Track both agencies' procedural deadlines.
• One-year audit clock. Wyo. Stat. § 39-15-108(c)(ii) requires the audit to be completed within one (1) year of the engagement notice. Document any auditor delay, extension request, or scope expansion in writing — the clock can be a powerful negotiating lever.
• Three-year look-back. Sales and use audits are limited to three years preceding the engagement absent fraud or gross negligence. Severance audits use a different limitations regime (see Wyo. Stat. § 39-14-208(b) for coal; verify per mineral).
• No Wyoming income tax. Do not waste pages reconciling federal taxable income to Wyoming taxable income — there is no Wyoming taxable income. Federal returns are relevant only for revenue, expense, and asset cross-checks.
• Wayfair-era nexus. As of July 1, 2024, only the $100,000 gross-revenue threshold under Wyo. Stat. § 39-15-501 applies; the 200-transaction prong was repealed by HB 197 (2024). Remote sellers prior to 7/1/2024 may have been required to register under the now-repealed transaction threshold and should evaluate whether continued registration remains necessary.
• Marketplace facilitators. Marketplace facilitator sales do not count toward an individual seller's $100,000 threshold under Wyo. Stat. § 39-15-501.1. Confirm marketplace certifications during audit.
• Direct-pay permits. Holders of a direct-pay permit under Wyo. Stat. § 39-15-107.1 self-accrue use tax and present a different audit profile; obtain the permit and any periodic reports.
• Voluntary disclosure. Wyoming runs a voluntary disclosure program (DOR Form VDA) that limits look-back to three years and waives most penalties. If pre-audit exposure is identified, weigh VDA versus continuing the audit.
• Severance specifics. Severance audits hinge on point of valuation, deductible costs (gathering, processing, transportation), and methodology (proportionate-profits vs. netback). Engage a petroleum / mining engineer expert early.
