The Case You Didn’t See Coming

Imagine this: you're the proud owner of a micro-entrepreneurial BV. You rent a facility from your local municipality, say, a swimming pool building and you invest in making it usable. You install lighting, HVAC, flooring, internal walls. You capitalize it, depreciate it. All looks fiscally sound.

Now here's the plot twist: that building is owned by the municipality, which doesn’t conduct a business with it. No profit motive, no Corporate Income Tax (CIT) liability, no tax book value. Your accountant shrugs. The municipality shrugs. But the Belastingdienst? It doesn’t shrug.

Instead, it applies Article 3.30a, paragraph 7 of the Dutch Income Tax Act 2001, a rule many small businesses and their advisors underestimate or misread, especially when the landlord is a non-taxable public body.

What's the Law Actually Saying?

Let’s break it down in plain terms:

• You (X BV) are renting a building from Municipality Y.
• Municipality Y owns the building but doesn’t run a business with it → no CIT liability → no tax book value assigned.
• You, the tenant, make significant improvements → You want to depreciate those tenant investments.
• But Article 3.30a(7) kicks in: since you and the landlord are affiliated entities, depreciation must be calculated as if you both co-invested in the same asset.
• Problem: there's no official tax book value for the building because the landlord isn’t taxable.
• Solution: the Knowledge Group (KG:213:2025:8) confirms: a notional book value must be constructed, as if the municipality had been taxable and had placed the building in its fiscal sphere from the beginning.

Bottom line: you can't ignore the landlord's fiscal vacuum. You must simulate their book value and then see if your investment exceeds the floor value (100% WOZ in this case). Only then can you decide if depreciation is allowed.

Why This Matters to You as a Small Business Owner

For Dutch micro and small entrepreneurs—especially those renting public infrastructure (sport centers, libraries, city-owned offices), this ruling cuts deeper than you think.

1. Affiliation is broader than most realize.
   Even if the municipality isn't “doing business,” its ownership of your BV creates a fiscal link. The tax office will treat you as intertwined.
2. You bear the risk of depreciation denial.
   If you invest in a leased space assuming automatic depreciation, you could be overstating your deductions. That means a nasty correction, interest, and penalties, years later.
3. WOZ isn't the magic solution.
   Even though WOZ (real estate value) is used as a reference, it only serves as a cap. You must first simulate the lessor’s “should-have-been” tax position.
4. Tax simplifications don’t apply in related-party setups.
   If your tenant investment would be clearly depreciable in a commercial third-party lease, that logic may not hold in affiliated situations. The law explicitly limits this workaround.

Linda’s Ledger Lessons

1. Run the Affiliation Check, Early.

Before you invest in your landlord’s building, ask: is the landlord a shareholder, director, or public body connected to your structure? If yes, prepare for Article 3.30a scrutiny.

2. Simulate the “phantom” tax book value.

If the landlord has no tax value, you must build one. Historical cost, age, useful life, and residual value must all be estimated—and documented, as if the landlord were taxable. This isn’t guesswork; it’s methodical.

3. Document the hell out of it.

This simulation must be audit-proof. The Belastingdienst doesn’t accept “we didn’t know” or “but they’re a municipality.” Use independent valuations, expert input, and link each investment to its depreciation logic.

4. Align with your auditor, before you file.

This is not your average line on a tax return. Your ZENTRIQ™ Auditor or equivalent should sign off on the logic, especially if your total investment is substantial.

Final Word

This ruling reminds us that the tax code does not care how small your business is—it cares how rigorous your assumptions are. If you lease from government entities, don’t assume fiscal simplicity. When the line between ownership, affiliation, and investment blurs, the depreciation rules tighten.

Small business owners in the Netherlands must learn to think like auditors, not just entrepreneurs. And if you’re renting from your local gemeente? Think twice before calling your renovation a write-off.
