Section 1 — Quick Reference

Components of Loonheffingen [T1]

Volksverzekeringen Rates 2025 [T1]

These are withheld from the employee's gross salary (combined with wage tax in bracket 1 rate of 35.82%).

Werknemersverzekeringen (Employer Contributions) 2025 [T1]

AWf Premium — Contract Type Distinction [T1]

Conditions for low rate:

• Written permanent contract (schriftelijke arbeidsovereenkomst voor onbepaalde tijd)
• Not an on-call contract (geen oproepovereenkomst)
• Employee works ≥ contracted hours (no excessive overtime correction needed)

Wage Tax Tables 2025 [T1]

The loonbelasting/premie volksverzekeringen are computed using Belastingdienst-provided tax tables:

Section 2 — Werkkostenregeling (WKR) — Work Cost Scheme

Concept [T1]

The WKR allows employers to provide tax-free benefits to employees within a "free space" (vrije ruimte) budget. Benefits exceeding the free space are subject to 80% flat-rate employer tax (eindheffing).

Vrije Ruimte 2025 [T1]

Example: Employer with EUR 1,000,000 wage base:

• Free space = EUR 400,000 × 1.92% + EUR 600,000 × 1.18% = EUR 7,680 + EUR 7,080 = EUR 14,760

WKR Categories [T1]

Gerichte Vrijstellingen — Key Amounts 2025 [T1]

Eindheffing (Flat-Rate Tax on Excess) [T1]

Gebruikelijkheidstoets: A single benefit provision cannot exceed EUR 2,400 per employee per occasion under the WKR. If it does, it must be individually taxed or split.

Section 3 — Filing Obligations and Deadlines

Section 4 — Required Inputs and Refusal Catalogue

Required Inputs

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.

Refusal Catalogue

R-LH-1 — No payroll data available. "Cannot compute loonheffingen without payroll run data. Provide at minimum gross salary totals per period."

R-LH-2 — Contract types unclear. "Cannot determine AWf rate (2.64% vs 7.64%) without confirmed contract types. Flag all employees as flex rate (conservative) until confirmed."

R-LH-3 — WKR allocation undocumented. "Cannot confirm vrije ruimte compliance without benefit-by-benefit administration. Flag for payroll advisor."

R-LH-4 — Anonymous employee (no BSN). "Must apply 52% anonymous rate. Cannot file normally without BSN and ID copy."

R-LH-5 — 30% ruling status unclear. "Cannot apply extraterritorial exemption without confirmed Belastingdienst ruling. Apply standard treatment."

Section 5 — Computation Examples

Example: Monthly Payroll Tax Computation

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

Example: WKR Assessment

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)

Section 6 — Control Checks and Red Flags

Section 7 — Official Source Verification Requirements

Before any rate, threshold, or deadline is used in output:

1. Verify payroll filing instructions on belastingdienst.nl/loonheffingen
2. Verify premium rates in the annual "Nieuwsbrief Loonheffingen" (Belastingdienst)
3. Verify statutory text on wetten.overheid.nl (Wet LB 1964, Wfsv)
4. Record exact URL and retrieval date (YYYY-MM-DD)
5. If source unavailable or conflicting: mark as UNVERIFIED and require professional confirmation

Section 8 — Escalation Points

Escalate to a qualified salarisadviseur or belastingadviseur when:

• Employee/contractor classification (dienstverband vs. opdracht) is unclear
• 30% ruling eligibility or application questions
• Cross-border employment (posting, frontier worker, split payroll)
• Payroll corrections affecting multiple prior periods
• Werknemersverzekeringen premium disputes with UWV
• WKR exceeds vrije ruimte by material amount (> EUR 10,000)
• Reorganisation or mass dismissal payroll implications
• Expatriate or DGA compensation structuring

All positions must be reviewed and signed off by a qualified Dutch belastingadviseur or salarisadministrateur before filing.
