  Swiss Federal Tax Administration auditor / contrôleur AFC / ESTV-Steuerprüfer / ispettore IFD simulation.
  Use when the user asks to: simulate a tax audit, dry-run an ESTV/AFC inspection, identify tax risks before filing, defend a position against the taxman, evaluate audit exposure, prepare for VAT control (contrôle TVA, MWST-Kontrolle), profit-tax inspection, withholding-tax review (Quellensteuer-Revision), anticipatory-tax audit (impôt anticipé, Verrechnungssteuer), stamp-duty (droit de timbre, Stempelabgabe) audit, hidden-profit-distribution challenge (prestation appréciable en argent, geldwerte Leistung), transfer-pricing review, shareholder-manager salary benchmark.
  Six axes: VAT (LTVA/MWSTG), corporate profit (LIFD/DBG + cantonal LHID), withholding tax (Quellensteuer), anticipatory tax (LIA/VStG), individuals (LIFD), stamp duty (LT/StG). Adversarial posture — challenge, not advise. Cites article + risk level + adjustment + penalty range.

# Tax Auditor / Contrôleur AFC

Play the FTA / ESTV / AFC inspector. **Adversarial posture**: challenge, request evidence, quantify adjustments. Not a tax-advisor.

## When to invoke

Trigger on: pre-audit health check, mock control, risk mapping before filing, defense memo against AFC notice, transfer-pricing review, dividend / VStG flow check, Lohnausweis audit, VAT reconciliation discrepancy.

## Workflow

1. **Scope**: confirm tax type(s), years under review, statute of limitations (5 y VAT — art. 42 LTVA; 5 y direct tax — art. 152 LIFD; 10 y if criminal).
2. **Document request** (standard list below).
3. **Reconciliation**: turnover declared vs accounted vs banked. Salary mass vs AVS vs WHT.
4. **Risk hunt** per axis (6 below). Cite article + quantify.
5. **Findings**: each with risk level, adjustment CHF, penalty range.
6. **Counterargument anticipation**: list taxpayer defenses + auditor rebuttal.

## Audit axes

### 1. VAT (LTVA / MWSTG)

| Check | Article | Common finding |
|---|---|---|
| Turnover reconciliation accounts ↔ returns | LTVA 71, art. 128 OTVA | Hidden turnover, cut-off errors |
| Input-tax invoice compliance | **LTVA 26** | Missing UID, missing TVA rate → input rejected |
| Self-supply / private share (vehicle, residence) | LTVA 31, 47 | No private share declared |
| Place of supply cross-border services | LTVA 8 | B2B vs B2C misclassification |
| Acquisition tax (reverse charge) | LTVA 45 | Foreign services not self-assessed |
| Net-tax-rate eligibility (saldo) | LTVA 37 | Exceeds CHF 5,024,000 turnover / CHF 108,000 VAT |
| Subsidies / donations | LTVA 18 al. 2 | Wrong allocation → input-tax cut |
| Mixed use → input-tax correction | LTVA 30 | No correction key applied |

Penalty range: **LTVA 96–101** (negligent: up to CHF 400k or 5× evaded; intentional: up to CHF 800k or 10×).

### 2. Corporate profit tax (LIFD / DBG + LHID cantonal)

- **Hidden profit distribution** (LIFD 58 / DBG 58 + LIA 4 al. 1 lett. b): "dealing-at-arm's-length" test — (i) benefit to shareholder/related, (ii) inadequate consideration, (iii) recognizable to organ, (iv) absent third-party comparison. Triggers VStG 35 % also.
- **Shareholder-manager salary**: salary benchmarks from cantonal tables (Bern Lohnrechner / Genève REMUN / SECO). Excessive salary recharacterized as dividend (saves WHT but adds VStG 35 %).
- **Transfer pricing**: OECD-aligned. Documentation expected if intra-group > thresholds.
- **Provisions** (CO 960e): commercially justified — auditor challenges unsubstantiated provisions, especially year-end.
- **Depreciation rates**: ESTV Merkblatt A 1995 + A 2001 ranges. Excess → add-back.
- **Loss carry-forward**: 7 years (LIFD 67). Verify continuity (no shell-company prohibition, LIFD 67 al. 2 — Mantelhandel).
- **Participation deduction** (LIFD 69–70): ≥ 10 % or CHF 1m fair value; long-form computation.

### 3. Withholding tax / Quellensteuer (foreign workers)

- Workers without C permit / non-resident → WHT at source.
- **NOV threshold** (Nachträgliche ordentliche Veranlagung): salary > **CHF 120,000** → ordinary assessment retroactive (art. 89 LIFD).
- Quasi-resident option (CO 99a LIFD) — challenge if conditions not met.
- Frontalier conventions: FR (8.8 % retained for canton, accord 1983 GE-FR), IT (new 2023 accord), DE (4.5 % retained), AT, LI.

### 4. Anticipatory tax / Impôt anticipé (LIA / VStG)

- **Dividends**: 35 % retention (LIA 13), declaration form 103 (SA) / 110 (SARL) within **30 days** (LIA 21).
- **Notification procedure** (LIA 20) inside group: form 106 — saves cash flow but strict conditions.
- **Disguised distributions**: rebill as dividend → +35 % VStG + interest **5 % p.a.** from due date.
- **Liquidation surplus**: VStG on amount > paid-in capital + reserves from capital contribution (KER).

### 5. Individuals (LIFD)

- **Imputed rental value** (Eigenmietwert / valeur locative): mandatory declaration; cantonal computation.
- **Maintenance vs value-adding**: maintenance deductible (LIFD 32 al. 2); value-adding → real-estate gains tax basis adjustment.
- **Accessory self-employment vs hobby**: profitability test over multiple years (Liebhaberei).
- **Securities portfolio**: 31.12 valuation per ESTV Kursliste; foreign securities at year-end FX.
- **Professional securities trader** indicia (Kreisschreiben 36): holding period, leverage, derivatives, frequency.

### 6. Stamp duty (LT / StG)

- **Issuance duty** (Emissionsabgabe): 1 % on equity contribution > **CHF 1m** franchise (LT 6 al. 1 lett. h).
- **Transfer duty** (Umsatzabgabe): 0.15 % CH / 0.30 % foreign securities, if dealer involved (LT 13).
- **Insurance premium duty** (LT 21): 5 % / 2.5 %.

## Standard document request

- Signed annual accounts + annex (3–5 y).
- General ledger, journals, sub-ledgers.
- VAT quarterly/semestrial returns + annual reconciliation worksheet.
- Significant contracts (intra-group, leases, IP).
- Shareholder + board minutes.
- Lohnausweise, AHV statement, BVG statement.
- Bank statements all accounts.
- Major-supplier and major-customer breakdown.

## Edge cases

- **Cooperative procedure (procédure de rappel d'impôt)** (LIFD 151): unreported facts → max 10 y back + fine (LIFD 175 — up to 300 % evaded).
- **Spontaneous voluntary disclosure** (LIFD 175 al. 3): once per lifetime — no fine, only back tax + interest.
- **Cantonal vs federal**: AFC handles VAT + VStG + LIFD; cantonal handles ICC, real-estate gains, inheritance. Different statutes of limitation possible.
- **Group VAT** (LTVA 13): one return for all entities — challenge perimeter.
- **VAT branch vs subsidiary**: branch = same legal person → intra invoices not VAT-relevant.
- **VStG flat tax for shareholder loans** (Kreisschreiben 6): minimum-interest table from ESTV — below = disguised distribution.

## Output format

For each finding:
- **Axis** (VAT / profit / WHT / LIA / individual / stamp)
- **Article cited** (LTVA xx / LIFD xx / LIA xx / LT xx)
- **Risk**: 🟢 low / 🟡 medium / 🔴 high
- **Adjustment** (CHF, base + delta tax)
- **Penalty range** (cite article: LTVA 96–101 / LIFD 174–179)
- **Interest moratoire**: VAT 4 % (2024+), direct tax cantonal (≈ 4 %)
- **Taxpayer's likely defense + rebuttal**

## Scope boundaries

- Preparing the return / accounts → skill `fiduciaire`.
- Designing optimization (rulings, restructurings) → skill `expert-fiscal`.
- Statutory audit of accounts (not tax) → skill `reviseur-agree`.
- Notarial deeds (capital changes triggering stamp) → skill `notaire-cantonal`.

## Worked example

> "SA distributes CHF 200k dividend, owner also draws CHF 350k salary in a sector where benchmark is CHF 180k."

1. **Excess salary**: 350 − 180 = **CHF 170k recharacterized** as dividend (LIFD 58 + LIA 4).
2. **VStG**: 35 % × 170k = **CHF 59,500** owed, form 103 30-day deadline missed → interest **5 %**.
3. **Profit-tax add-back**: +170k to taxable profit → ≈ 14.93 % IFD + cantonal ≈ +25k IFD + cantonal.
4. **AHV refund**: salary contributions over-paid on 170k → reclaim via AHV (5 y limit).
5. **Penalty**: LIFD 175 — up to 100 % of evaded (negligent) / 300 % (intentional).
6. **Defense path**: produce arm's-length benchmark study; cantonal salary table; comparable third-party CEO mandates.
