Finding a tax advisor in the Netherlands who actually speaks your language

Why finding an English-speaking tax advisor is harder than it should be

Last month I had a call with Sarah from London. She'd been in the Netherlands for three years and had never filed a Dutch tax return. Not because she didn't want to — but because every advisor she called only spoke Dutch. Her employer's HR department? They just shrugged. "You'll have to figure that out yourself."

I hear this more than you'd think. The vast majority of Dutch tax firms operate exclusively in Dutch. Makes sense — most of their clients are Dutch. But for the 100,000+ expats arriving here every year, it's a real problem.

The big four — Deloitte, PwC, EY, KPMG — speak English, obviously. But their rates start at €300 per hour. For a straightforward tax return, you're looking at €1,000+. For most people, that's absurd.

So where does that leave you? Somewhere between Google Translate and bankruptcy, apparently. But it doesn't have to be that way.

What to look for (and what to avoid)

A good English-speaking tax advisor needs more than just language skills. Here's what I'd check:

Professional registration

Look for membership in the RB-register (Register Belastingadviseurs) or NOB (Nederlandse Orde van Belastingadviseurs). These are the professional bodies for tax advisors in the Netherlands. Not every good advisor is a member, but it's a solid quality indicator.

Expat-specific experience

This is the big one. Ask about their experience with the M-form — that's the tax return you file in the year you move to or from the Netherlands. It's notoriously complex, and many Dutch tax advisors have never touched one. If they hesitate when you mention it, they haven't done many expat returns.

Your advisor should also understand how the 30% ruling interacts with your other income, Box 3 assets (savings and investments above the €57,684 tax-free threshold in 2025), and any tax treaty benefits between the Netherlands and your home country.

Red flags

• Hourly billing without a clear scope — you'll have no idea what the final bill looks like
• No M-form experience
• They can't explain Box 3 deemed returns (1.37% on savings, 5.88% on investments in 2025, taxed at 36%)
• They seem unfamiliar with the 30% ruling's impact on Box 2 and Box 3

One client came to us after his previous advisor filed his return without accounting for his UK pension. That mistake cost him €3,200 in unnecessary taxes. Experience matters.

How much does it cost?

Let me give you the honest breakdown, because nobody else seems to want to:

• Big four firms: €300-€500/hour — overkill for most individuals
• Mid-size firms: €150-€250/hour — reasonable, but hourly billing is unpredictable
• Boutique expat specialists: €200-€500 per return (fixed fee)
• Jan de Belastingman: Fixed fee. You know what you pay before we start. No surprises.

I'm a believer in fixed pricing. Not because my hourly rate isn't worth it, but because I think you should know exactly what you're paying before we begin. That's just fair.

For a standard expat return (employed, no side income), you're typically looking at €250-€400. Add the M-form or foreign assets, and it goes up to €400-€600. Still a fraction of what the big firms charge.

What your first meeting should look like

Come prepared. The better prepared you are, the faster (and cheaper) things go. Here's your checklist:

• BSN number — your Dutch citizen service number
• Jaaropgave — annual income statement from your employer(s)
• DigiD — or authorize someone to file on your behalf
• WOZ-beschikking — property valuation notice (if you own a home)
• Mortgage details — outstanding amount, interest paid
• Foreign assets overview — bank accounts, investments, property abroad
• Previous tax returns — from your home country and NL (if any)

A good advisor won't just fill in forms. They'll proactively spot opportunities. "Did you know you can deduct this?" "Have you considered applying for the 30% ruling?" That's the difference between a bookkeeper and an advisor.

If your first meeting feels like an interrogation where you're just answering questions, that's a bad sign. It should feel like a conversation where both sides are thinking about how to optimize your situation.

When to switch advisors

Sometimes new clients tell me: "My previous advisor was fine, I guess." And then I ask: "Did they ever call you when something changed?" Silence.

A good advisor calls YOU when something changes. When the 30% ruling gets modified, when new deductions become available, when your situation changes because of a move or job switch.

Signs it's time to switch:

• Your advisor only responds when you reach out first
• You get surprises on your invoice
• You feel like they're just filling in forms, not thinking strategically
• They can't answer your questions about Box 3 or the 30% ruling
• They don't know the difference between the P-form and the M-form

My rule of thumb: if your advisor doesn't tell you at least one thing per year that you didn't already know, something's wrong. Either with them, or with your willingness to listen. Usually it's the former.

Tax advisory isn't just about compliance. It's about making sure you keep as much of your hard-earned money as legally possible. And for that, you need someone who speaks your language — literally and figuratively.
