83## Section 2 -- Required inputs and refusal catalogue
84 
85### Required inputs
86 
87Before computing any ZZP deduction, you MUST know:
88 
891. Business structure -- eenmanszaak, maatschap/VOF, or BV (BV is out of scope)
902. Does the client meet the urencriterium (1,225 hours)? -- required for zelfstandigenaftrek and startersaftrek
913. Is this a starter? -- determines startersaftrek eligibility
924. Gross profit from the enterprise (winst uit onderneming) -- needed to compute deduction order
935. Total business investments in the year -- needed for KIA
946. Does the fiscal partner work in the business unpaid or for less than EUR 5,000? -- meewerkaftrek
957. Does the client have an existing FOR balance from pre-2023? -- FOR release rules
96 
97If the urencriterium status is unknown, STOP. Many deductions depend on it.
98 
99### Refusal catalogue
100 
101**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."
102

104 
105**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.

153## Section 4 -- Deduction computation rules
154 
155### 4.1 Zelfstandigenaftrek (Tier 1)
156 
157Legislation: Wet IB 2001 Article 3.76
158 
1592025 amount: EUR 2,470 (standard); EUR 1,235 if AOW age reached at start of year.
160 
161Requirements: 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).
162 
163### 4.2 Urencriterium (Tier 1 / Tier 2)
164 
165Legislation: Wet IB 2001 Article 3.6
166 
167Threshold: at least 1,225 hours per calendar year on enterprise activities. Counts: direct client work, administration, sales, professional development, purchasing, business meetings, strategic planning. Does NOT count: travel time, commuting, personal development unrelated to business, sick leave, vacation.
168 
169NOT pro-rated for part-year. Full 1,225 hours must be met even if business started mid-year. Flag for reviewer if hours are between 1,200 and 1,300 (borderline).
170 
171### 4.3 Startersaftrek (Tier 1)
172 
173Legislation: Wet IB 2001 Article 3.76 lid 3
174 
1752025 amount: EUR 2,123 on top of zelfstandigenaftrek. 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.
176 
177Special 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.
178 
179### 4.4 MKB-winstvrijstelling (Tier 1)
180 
181Legislation: Wet IB 2001 Article 3.79a
182 
1832025 rate: 12.7% of qualifying profit. Calculated on profit AFTER ondernemersaftrek. Urencriterium is NOT required. All ondernemers qualify.
184 
185If qualifying profit is negative (loss), the MKB-winstvrijstelling reduces the loss by 12.7% (works against the taxpayer in loss years).
186 
187### 4.5 FOR -- abolished (Tier 1)
188 
189The 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.
190 
191### 4.6 KIA (Tier 1)
192 
193Legislation: Wet IB 2001 Article 3.41
194 
195Each 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.
196 
197Disinvestment addition: if KIA-claimed asset sold within 5 years, proportional addition to profit applies.
198 
199### 4.7 Willekeurige afschrijving voor starters (Tier 1)
200 
201Legislation: Wet IB 2001 Article 3.34
202 
203Qualifying starters may depreciate business assets at any pace (up to 100% in year 1). Requires startersaftrek eligibility. Asset must cost >= EUR 450. Residual value floor still applies. For buildings, limited to WOZ value.
204 
205### 4.8 Meewerkaftrek (Tier 2)
206 
207Legislation: Wet IB 2001 Article 3.78
208 
209| Hours worked by partner per year | Deduction (% of profit) |
210|---|---|
211| 525 -- 874 | 1.25% |
212| 875 -- 1,224 | 2.00% |
213| 1,225 -- 1,749 | 3.00% |
214| 1,750+ | 4.00% |
215 
216Partner 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.
217

219 
220## Section 5 -- Computation order
221 
222Legislation: Wet IB 2001 Article 3.2 et seq.
223 
224```
2251. Winst uit onderneming (profit from enterprise)
226 = Revenue - Costs - Depreciation - KIA
2272. Minus: Ondernemersaftrek
228 = Zelfstandigenaftrek + Startersaftrek + Meewerkaftrek + Stakingsaftrek
2293. = Profit after ondernemersaftrek
2304. Minus: MKB-winstvrijstelling (12.7% of line 3)
2315. = Taxable profit from enterprise
2326. Add: Other Box 1 income (employment, pension, periodic payments)
2337. Minus: Personal deductions (hypotheekrenteaftrek, lijfrente, etc.)
2348. = Belastbaar inkomen Box 1
2359. Apply progressive Box 1 rates
236```
237 
238Key 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.
239 
240---
241 
242## Section 6 -- FOR balance management and stakingsaftrek
243 
244### 6.1 Existing FOR balances (Tier 1)
245 
246| Situation | Treatment |
247|---|---|
248| FOR balance on 31 Dec 2022 | Remains on balance sheet; not immediately taxed |
249| Conversion to lijfrente | Premium deductible within jaarruimte/reserveringsruimte limits |
250| Release without lijfrente | Added to Box 1 taxable income at progressive rates |
251| Business cessation | FOR must be released; stakingsaftrek (max EUR 3,630 in 2025) may apply if converted within 6 months |
252 
253### 6.2 What replaced FOR
254 
255Entrepreneurs use jaarruimte to make actual lijfrente contributions. Jaarruimte is based on profit and pension accrual.
256 
257---
258 
259## Section 7 -- Edge case registry
260 
261### EC1 -- Hours just below 1,225 (Tier 2)
262Situation: Client claims 1,210 hours, wants to include 20 hours of travel time.
263Resolution: 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.
264 
265### EC2 -- Loss year with startersaftrek (Tier 1)
266Situation: Starter has profit of EUR 1,000 but qualifies for EUR 4,593 total deduction.
267Resolution: 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).
268 
269### EC3 -- Loss year without startersaftrek (Tier 1)
270Situation: Non-starter has profit of EUR 1,500, zelfstandigenaftrek EUR 2,470.
271Resolution: Zelfstandigenaftrek limited to EUR 1,500. Remaining EUR 970 is lost. MKB-winstvrijstelling on zero = zero.
272 
273### EC4 -- FOR balance from pre-2023, business continues (Tier 1)
274Situation: Client has FOR balance of EUR 15,000 from 2022. Business still active.
275Resolution: Balance remains. No new additions. No forced release while business continues. May convert to lijfrente voluntarily.
276 
277### EC5 -- KIA on personal car above EUR 12,000 (Tier 1)
278Situation: Client purchases car with catalogue value EUR 25,000, 70% business use.
279Resolution: Excluded from KIA regardless of business use. Normal depreciation (based on business %) does apply.
280 
281### EC6 -- Disinvestment addition triggered (Tier 1)
282Situation: Machine purchased for EUR 5,000 in 2023, KIA EUR 1,400 (28%). Sold in 2025 for EUR 3,000.
283Resolution: Disinvestment addition: EUR 3,000 x 28% = EUR 840 added to 2025 profit.
284 
285### EC7 -- Partner paid EUR 6,000 (Tier 1)
286Situation: Fiscal partner works 900 hours, receives EUR 6,000.
287Resolution: Meewerkaftrek requires < EUR 5,000 payment. EUR 6,000 exceeds threshold. No meewerkaftrek. The EUR 6,000 is deductible business expense; taxable for partner.
288 
289### EC8 -- Mid-year starter, urencriterium not met (Tier 1)
290Situation: Business starts 1 September, client works 800 hours by 31 December.
291Resolution: 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.

358 
359## Section 10 -- Prohibitions and disclaimer
360 
361### Prohibitions
362 
363- NEVER apply the zelfstandigenaftrek without confirming the urencriterium is met -- 1,225 hours is a hard threshold
364- NEVER pro-rate the urencriterium for part-year businesses -- the full 1,225 hours must be met
365- NEVER include travel time in the urencriterium count -- it is explicitly excluded
366- NEVER compute a new FOR addition for 2023 or later -- the FOR has been abolished
367- NEVER apply the startersaftrek beyond the first 3 qualifying years in a 5-year window
368- NEVER forget that MKB-winstvrijstelling is calculated AFTER the ondernemersaftrek -- the order matters
369- NEVER apply the profit limitation to the zelfstandigenaftrek when the startersaftrek also applies
370- NEVER claim KIA on cars with catalogue value above EUR 12,000
371- NEVER claim KIA on individual assets costing less than EUR 450
372- NEVER ignore the disinvestment addition when a KIA-claimed asset is sold within 5 years
373- NEVER present computed deductions as definitive -- always direct client to their belastingadviseur
