|---|---|
| Benefits exceeding vrije ruimte | 80% eindheffing (paid by employer) |
| Benefits exceeding EUR 2,400/occasion (gebruikelijkheidstoets) | Cannot use WKR — must be individually taxed |
Periodic Filing
| Obligation | Frequency | Deadline |
|---|---|---|
| Loonaangifte (payroll tax return) | Per pay period (monthly or 4-weekly) | Last day of month following pay period |
| Payment of loonheffingen | Per pay period | Same as filing deadline |

| WKR eindheffing determination | In first payroll return of following year | Determine if vrije ruimte exceeded; report 80% tax |
| Renseignementen (information returns) | Various | Third-party payments > EUR 5,000/year |
Key Dates
| Event | Date |
|---|---|
| Payroll return deadline (monthly) | Last day of month + 1 month |
| Annual employer statement (jaaropgave) | 28 February |
| WKR assessment moment | 31 December (assess full year usage) |
| Report eindheffing | First return period of new year |
Minimum viable: Payroll run summary for the period. Employee count and contract types. Gross salary totals.
Recommended: Detailed payroll journal, WKR administration (benefits provided per category), sector classification for Whk, AWf contract type split.
Ideal: Full payroll software export, employment contracts, WKR policy document, expense claim registers, prior-year WKR reconciliation, UWV correspondence.
Given:
- Gross monthly salary: EUR 5,000
- Employee: permanent contract, below AOW age
- No special deductions
Step 1: Determine loonbelasting + premie volksverzekeringen
→ Use white monthly table from Belastingdienst
→ Approximate: EUR 5,000 × 35.82% = EUR 1,791 (first bracket)
→ Actual amount per tax table (includes heffingskortingen)
Step 2: Employer premiums:
→ AWf (permanent): EUR 5,000 × 2.64% = EUR 132
→ Aof: EUR 5,000 × 5.82% = EUR 291 (small employer)
→ Whk: EUR 5,000 × 1.50% = EUR 75 (example sector rate)
→ Zvw: EUR 5,000 × 6.57% = EUR 328.50
Step 3: Total employer cost above gross:
→ EUR 132 + EUR 291 + EUR 75 + EUR 328.50 = EUR 826.50
Step 4: Employee net (approximate):
→ EUR 5,000 − EUR 1,791 + heffingskortingen (from table) = net salary
Given:
- Annual wage base (fiscale loonsom): EUR 800,000
- Benefits provided: Christmas packages EUR 8,000, staff party EUR 5,000, bicycle scheme EUR 3,000
Step 1: Calculate vrije ruimte:
→ EUR 400,000 × 1.92% = EUR 7,680
→ EUR 400,000 × 1.18% = EUR 4,720
→ Total: EUR 12,400
Step 2: Determine which benefits count:
→ Christmas packages: EUR 8,000 (vrije ruimte)
→ Staff party: EUR 5,000 (vrije ruimte)
→ Bicycle scheme: EUR 3,000 (vrije ruimte — not a gerichte vrijstelling)
→ Total allocated: EUR 16,000
Step 3: Excess:
→ EUR 16,000 − EUR 12,400 = EUR 3,600
Step 4: Eindheffing:
→ EUR 3,600 × 80% = EUR 2,880 (employer pays)
Control Checks and Red Flags
| Check | Issue if triggered |
|---|---|
| AWf rate mismatch vs contract type | Incorrect premium — back-payment risk |
| WKR benefit > EUR 2,400 per person per occasion | Gebruikelijkheidstoets failed — must individually tax |
| Vrije ruimte exceeded without eindheffing | Missing tax payment |
| Employee hours > 130% of contracted hours | AWf low rate at risk (herzieningsregeling) |
| Late filing (> 1 month) | EUR 65 fine per return; escalates |
| Missing jaaropgave | Employee cannot file IB return correctly |
| DGA on payroll below EUR 56,000 | Gebruikelijk loon non-compliance |
| No written employment contracts | All employees default to flex AWf rate |
