Self-Employment Tax for DAFT Entrepreneurs in the NL
When we registered our eenmanszaak at the KVK, we were focused on getting the Dutch-American Friendship Treaty (DAFT) visa approved. Taxes were a problem for later.
Later came fast. It turns out that running a sole proprietorship in the Netherlands as a US citizen means two countries want a piece of your self-employment income. Here's how it actually works.
The US Side: Self-Employment Tax Still Applies
If you're self-employed anywhere in the world, the IRS still expects you to pay self-employment tax. This is separate from income tax. It covers Social Security and Medicare.
The rate is 15.3% on your net self-employment income (12.4% for Social Security, 2.9% for Medicare). You pay this on top of whatever income tax you owe.
Here's the part that trips people up: the Foreign Earned Income Exclusion only reduces your income tax. It does nothing for self-employment tax. So even if you exclude over $120,000 of earned income, you still owe SE tax on all of it.
The Dutch Side: Social Contributions
The Netherlands has its own system. As a sole proprietor (eenmanszaak), you pay into the Dutch social insurance system through your income tax return. These contributions cover things like AOW (the Dutch state pension) and healthcare.
Dutch social contributions are built into the tax brackets. The first bracket includes roughly 27.65% in social premiums on top of income tax. It's not a separate line item like in the US -- it's baked into the rates.
If you're earning income in the Netherlands and paying Dutch social contributions, you may be paying into two social security systems at once. That's where the totalization agreement becomes important.
How the Totalization Agreement Helps
The US and the Netherlands have a bilateral agreement to prevent double social security taxation. Under this agreement, you generally pay into only one country's system at a time.
For most DAFT entrepreneurs living and working in the Netherlands, you'll pay into the Dutch system and can get an exemption from US self-employment tax (the Social Security portion). You'll still owe the 2.9% Medicare tax.
To claim the exemption, you need a Certificate of Coverage from the SVB (the Dutch social insurance bank). This proves you're covered under the Dutch system.
Dutch Tax Benefits for Self-Employed
The Netherlands actually treats self-employed people pretty well tax-wise. There are several deductions available:
Zelfstandigenaftrek (self-employed deduction): A fixed deduction from your profit if you work at least 1,225 hours per year in your business. This has been decreasing each year but still provides meaningful savings.
Startersaftrek (starter's deduction): An additional deduction for the first three years of your business. You can claim this three times in your first five years.
MKB-winstvrijstelling (SME profit exemption): A percentage reduction of your remaining profit after the above deductions. Currently 12.7%.
These deductions can significantly reduce your Dutch tax bill. Make sure your bookkeeping is solid so you can claim everything you're entitled to.
What You Actually Need to Do
Here's the practical checklist:
- Track your income carefully. You need clear records for both the IRS and the Belastingdienst (Dutch tax authority).
- File quarterly estimated taxes with the IRS if you expect to owe more than $1,000.
- Request a Certificate of Coverage from the SVB to avoid double Social Security.
- File your Dutch tax return (aangifte inkomstenbelasting) by May 1 each year.
- File your US tax return using the extended deadline for Americans abroad.
- Claim the Foreign Tax Credit for Dutch taxes paid to reduce your US tax bill.
Most DAFT entrepreneurs we know use a tax accountant who handles both US and Dutch returns. It's worth the cost. One missed deduction or credit can cost you more than the accountant's fee. Our guide on finding the right accountant can help.
FAQ
Q: Can I use the Foreign Earned Income Exclusion instead of the Foreign Tax Credit?
A: You can, but for self-employed people it's often less beneficial because FEIE doesn't reduce self-employment tax. Many expat tax advisors recommend the Foreign Tax Credit instead, especially if Dutch tax rates are higher than US rates on your income level. Run the numbers both ways or have your accountant compare.
Q: Do I need to charge Dutch BTW (VAT) on top of tracking income tax?
A: If your annual revenue exceeds the kleineondernemersregeling (small business scheme) threshold, yes. BTW is a separate obligation from income tax. You'll register for BTW, charge it on invoices, and file quarterly returns. This is separate from your US and Dutch income tax obligations.
Q: What happens if I don't get the Certificate of Coverage?
A: Without it, you could end up paying both US self-employment tax (15.3%) and Dutch social contributions. That's a lot of money going to two pension systems. Get the certificate. The SVB process is straightforward, and it can save you thousands per year.
