## Section 2 -- Required inputs and refusal catalogue

### Required inputs

- **Required inputs before computing ZZP deduction** — Before computing any ZZP deduction, you MUST know: 1. Business structure -- eenmanszaak, maatschap/VOF, or BV (BV is out of scope) 2. Does the client meet the urencriterium (1,225 hours)? -- required for zelfstandigenaftrek and startersaftrek 3. Is this a starter? -- determines startersaftrek eligibility 4. Gross profit from the enterprise (winst uit onderneming) -- needed to compute deduction order 5. Total business investments in the year -- needed for KIA 6. Does the fiscal partner work in the business unpaid or for less than EUR 5,000? -- meewerkaftrek 7. Does the client have an existing FOR balance from pre-2023? -- FOR release rules. If the urencriterium status is unknown, STOP. Many deductions depend on it.

### Refusal catalogue

- **R-NL-ZZP-1 -- BV structure** — Trigger: client operates through a BV (besloten vennootschap). Message: "This skill covers eenmanszaak and partnership participants only. BV corporate tax and salary/dividend structuring is outside scope. Please escalate to a qualified belastingadviseur."
- **R-NL-ZZP-2 -- International structure** — Trigger: client has cross-border business income or a permanent establishment in another country. Message: "International tax structures require treaty analysis. This skill covers domestic Dutch ZZP deductions only. Please escalate."
- **R-NL-ZZP-3 -- Fiscal unity or complex partnership allocations** — Trigger: client is part of a fiscal unity or asks about complex partnership profit allocation. Message: "Fiscal unity and complex partnership allocations are outside this skill's scope. Please escalate to a qualified belastingadviseur."

## Section 4 -- Deduction computation rules

- **Zelfstandigenaftrek AOW age 2025** — EUR 1,235  _(Wet IB 2001 Article 3.76)_
- **Zelfstandigenaftrek requirements** — Requirements: must qualify as ondernemer; must meet urencriterium (1,225 hours). The zelfstandigenaftrek cannot exceed profit before ondernemersaftrek, UNLESS the startersaftrek also applies (then no profit limitation).  _(Wet IB 2001 Article 3.76)_

### 4.2 Urencriterium (Tier 1 / Tier 2)

- **Urencriterium hours threshold** — 1,225 hours per calendar year  _(Wet IB 2001 Article 3.6)_

Flag for reviewer if hours are between 1,200 and 1,300 (borderline).  _(Wet IB 2001 Article 3.6)_

- **Startersaftrek requirements** — Requirements: qualifies for zelfstandigenaftrek; applied zelfstandigenaftrek in at most 2 of the preceding 5 years. Available in first 3 years of a 5-year window.  _(Wet IB 2001 Article 3.76 lid 3)_
- **Startersaftrek special rule** — Special rule: when startersaftrek applies, the combined deduction (zelfstandigenaftrek + startersaftrek) is NOT limited to profit. Can create negative income from enterprise that offsets other Box 1 income.  _(Wet IB 2001 Article 3.76 lid 3)_

### 4.4 MKB-winstvrijstelling (Tier 1)

- **MKB-winstvrijstelling 2025 rate** — 12.7% of qualifying profit  _(Wet IB 2001 Article 3.79a)_
- **MKB-winstvrijstelling rule** — Calculated on profit AFTER ondernemersaftrek. Urencriterium is NOT required. All ondernemers qualify. If qualifying profit is negative (loss), the MKB-winstvrijstelling reduces the loss by 12.7% (works against the taxpayer in loss years).  _(Wet IB 2001 Article 3.79a)_

### 4.5 FOR -- abolished (Tier 1)

- **FOR abolition rule** — The Fiscale Oudedagsreserve has been abolished as of 1 January 2023. No new additions permitted. Existing balances from pre-2023 remain on the balance sheet. Can be converted to lijfrente at any time. Released at business cessation (stakingsaftrek max EUR 3,630 in 2025 may apply). NEVER compute a new FOR addition for 2023 or later.

### 4.6 KIA (Tier 1)

- **KIA eligibility rules** — Each individual asset must cost at least EUR 450. Total qualifying investment must be at least EUR 2,901. Urencriterium NOT required. Excluded: land, residential buildings, cars > EUR 12,000, assets for lease, animals, goodwill, assets from connected persons.  _(Wet IB 2001 Article 3.41)_

### 4.8 Meewerkaftrek (Tier 2)

**Meewerkaftrek hours/percentage table**  _(Wet IB 2001 Article 3.78)_

| Hours worked by partner per year | Deduction (% of profit) |
| --- | --- |
| 525 -- 874 | 1.25% |
| 875 -- 1,224 | 2.00% |
| 1,225 -- 1,749 | 3.00% |
| 1,750+ | 4.00% |

- **Meewerkaftrek conditions** — Partner must work unpaid or receive < EUR 5,000. Urencriterium for entrepreneur NOT required. Flag for reviewer -- partner hours must be documented. Being phased out from 2027.  _(Wet IB 2001 Article 3.78)_

## Section 5 -- Computation order

- **Computation order steps** — 1. Winst uit onderneming (profit from enterprise) = Revenue - Costs - Depreciation - KIA 2. Minus: Ondernemersaftrek = Zelfstandigenaftrek + Startersaftrek + Meewerkaftrek + Stakingsaftrek 3. = Profit after ondernemersaftrek 4. Minus: MKB-winstvrijstelling (12.7% of line 3) 5. = Taxable profit from enterprise 6. Add: Other Box 1 income (employment, pension, periodic payments) 7. Minus: Personal deductions (hypotheekrenteaftrek, lijfrente, etc.) 8. = Belastbaar inkomen Box 1 9. Apply progressive Box 1 rates  _(Wet IB 2001 Article 3.2 et seq.)_
- **Key interaction between deductions** — Key interaction: zelfstandigenaftrek and startersaftrek reduce profit BEFORE MKB-winstvrijstelling, creating a multiplied effect. EUR 2,470 zelfstandigenaftrek reduces taxable income by EUR 2,470 + (12.7% x EUR 2,470) = EUR 2,784. KIA reduces profit at step 1, also included in MKB-winstvrijstelling base. The arbeidskorting (tax credit) is applied after computing gross tax.  _(Wet IB 2001 Article 3.2 et seq.)_

## Section 6 -- FOR balance management and stakingsaftrek

### 6.1 Existing FOR balances (Tier 1)

**FOR balances treatment table**

| Situation | Treatment |
| --- | --- |
| FOR balance on 31 Dec 2022 | Remains on balance sheet; not immediately taxed |
| Conversion to lijfrente | Premium deductible within jaarruimte/reserveringsruimte limits |
| Release without lijfrente | Added to Box 1 taxable income at progressive rates |
| Business cessation | FOR must be released; stakingsaftrek (max EUR 3,630 in 2025) may apply if converted within 6 months |

### 6.2 What replaced FOR

- **Jaarruimte replacement** — Entrepreneurs use jaarruimte to make actual lijfrente contributions. Jaarruimte is based on profit and pension accrual.

## Section 7 -- Edge case registry

### EC1 -- Hours just below 1,225 (Tier 2)

Situation: Client claims 1,210 hours, wants to include 20 hours of travel time. Resolution: Travel time does NOT count. Client does not qualify for zelfstandigenaftrek or startersaftrek. Still qualifies for MKB-winstvrijstelling and KIA (no hours requirement). Flag for reviewer.

### EC2 -- Loss year with startersaftrek (Tier 1)

Situation: Starter has profit of EUR 1,000 but qualifies for EUR 4,593 total deduction. Resolution: Full EUR 4,593 deducted (no profit limitation for starters). Loss of EUR 3,593 offsets other Box 1 income. MKB-winstvrijstelling reduces loss by 12.7% (loss becomes EUR 3,137).

### EC3 -- Loss year without startersaftrek (Tier 1)

Situation: Non-starter has profit of EUR 1,500, zelfstandigenaftrek EUR 2,470. Resolution: Zelfstandigenaftrek limited to EUR 1,500. Remaining EUR 970 is lost. MKB-winstvrijstelling on zero = zero.

### EC4 -- FOR balance from pre-2023, business continues (Tier 1)

Situation: Client has FOR balance of EUR 15,000 from 2022. Business still active. Resolution: Balance remains. No new additions. No forced release while business continues. May convert to lijfrente voluntarily.

### EC5 -- KIA on personal car above EUR 12,000 (Tier 1)

Situation: Client purchases car with catalogue value EUR 25,000, 70% business use. Resolution: Excluded from KIA regardless of business use. Normal depreciation (based on business %) does apply.

### EC6 -- Disinvestment addition triggered (Tier 1)

Situation: Machine purchased for EUR 5,000 in 2023, KIA EUR 1,400 (28%). Sold in 2025 for EUR 3,000. Resolution: Disinvestment addition: EUR 3,000 x 28% = EUR 840 added to 2025 profit.

### EC7 -- Partner paid EUR 6,000 (Tier 1)

Situation: Fiscal partner works 900 hours, receives EUR 6,000. Resolution: Meewerkaftrek requires < EUR 5,000 payment. EUR 6,000 exceeds threshold. No meewerkaftrek. The EUR 6,000 is deductible business expense; taxable for partner.

### EC8 -- Mid-year starter, urencriterium not met (Tier 1)

Situation: Business starts 1 September, client works 800 hours by 31 December. Resolution: 1,225 hours NOT pro-rated. No zelfstandigenaftrek or startersaftrek in 2025. MKB-winstvrijstelling and KIA still available. Year 1 of startersaftrek is not used up.
