Dutch taxes for Americans: three boxes, the 30% ruling and your US return

Short answer: once you live in Amsterdam, the Netherlands taxes your income in three "boxes," including a yearly tax on your savings and investments wherever they are. You still file with the IRS every year, and the foreign tax credit usually keeps you from paying twice.

The short version

• Box 1 taxes work and home income in 2026 at 35.75%, 37.56% and 49.50%, with the top rate starting above EUR 78,426 (about USD 87,550) for people under Dutch state pension age [1].
• Box 2 taxes income from a stake of 5% or more in a company at 24.5% and 31% [2]. Box 3 taxes a deemed return on your savings and investments at 36%, above a tax-free amount of EUR 59,357 (USD 66,260) per person in 2026 [1][3].
• The 30% ruling lets employers recruited from abroad pay up to 30% of salary tax-free in the Netherlands [4]. The IRS doesn't follow it.
• The US–Netherlands tax treaty (1992, amended by a 2004 protocol) has a saving clause in Article 24, so the US still taxes its citizens [5][6].
• A totalization agreement in force since November 1, 1990 keeps you from paying into both Social Security systems [7].

How the Dutch system works: three boxes

Back home, the IRS lumps almost everything onto one Form 1040. The Dutch Tax Administration (Belastingdienst) splits your income into three groups, each with its own rates [1][2][3]:

The Box 1 rates above are for people who haven't reached the Dutch state pension age (AOW age); rates are lower after that [1]. Tax credits (heffingskortingen) then reduce what you owe, depending on your situation. The Dutch tax year runs January to December, just like the US one, which makes matching the two returns easier.

Box 3 and your US accounts

Box 3 is the one that catches Americans off guard. The Netherlands doesn't tax your actual investment income here. It assumes your wealth earned a set return and taxes that at 36% [1][3]. Your US checking account, brokerage account and that rental condo in Ohio can all land in Box 3 once you're a Dutch resident.

After court rulings against the old system, the Belastingdienst lets people show that their actual return was lower than the deemed one, and there's a process to correct past years [3]. The rules have been in motion for several years, so check the current year's method before you file.

The 30% ruling

If your employer recruited you from abroad for specific expertise, you may qualify for the expat scheme, known as the 30% ruling. The conditions [4]:

1. You're an employee of the employer applying.
2. You have specific expertise that's hard to find in the Netherlands.
3. You were recruited from outside the Netherlands.
4. You have a valid decision (beschikking) from the Belastingdienst.

You and your employer apply together, and the Belastingdienst replies within eight weeks. Your employer can then pay up to 30% of your salary as a tax-free allowance for the extra costs of living abroad, or reimburse actual costs instead. The employer isn't required to pay the full 30%, so agree on it before you sign [4].

Here's the American catch: Uncle Sam doesn't recognize the 30% ruling. The tax-free part is still income on your US return. Because the ruling lowers your Dutch tax, you have fewer Dutch taxes to credit against your US bill. See the 30% ruling for Americans for the salary tests and the math.

The US–Netherlands tax treaty

The income tax treaty dates from 1992 and was updated by a 2004 protocol [5]. It sets which country taxes pensions, dividends, interest and business profits first, and how double taxation gets relieved. The IRS publishes the treaty, the protocol and two Technical Explanations [5].

The fine print that matters most for Americans is the saving clause in Article 24 (Basis of Taxation). It lets the US tax its citizens as if the treaty didn't exist, with a list of exceptions [6]. So the treaty doesn't get you out of filing a US return. What helps is Article 25, on eliminating double taxation, which includes special foreign tax credit rules for when the US taxes a citizen under the saving clause [6]. Pensions are covered in Article 19 [6].

The treaty doesn't cover social security taxes. That's the job of a separate agreement [6].

Totalization: one Social Security system, not two

The US and the Netherlands signed a Social Security agreement on December 8, 1987, and it took effect on November 1, 1990 [7]. In general:

• If you work for a Dutch employer, you pay into the Dutch system, not US Social Security.
• If a US employer sends you to Amsterdam for a limited time, you can usually stay in the US system. Your employer requests a certificate of coverage to prove it.
• Credits earned in both countries can be combined to qualify for benefits.

Our guide to tax treaties and totalization agreements explains how the combined credits work.

Your US return: FEIE or foreign tax credit?

You file Form 1040 every year as a US citizen, with an automatic extension to June 15 when you live abroad. Then you pick your tools:

Because Dutch Box 1 rates run from 35.75% to 49.50% [1], many Americans in Amsterdam pay more Dutch tax than they'd owe the IRS, and the foreign tax credit wipes out the US tax on their salary. Unused credits can often be carried forward. The picture changes if you have the 30% ruling, big investment income or US-source income, so run the numbers both ways.

Reporting rules that follow you

Living in Amsterdam doesn't switch off US reporting:

• FBAR (FinCEN Form 114) if your foreign accounts together top USD 10,000 at any point in the year. Dutch banks report US account holders under FATCA, so assume the IRS knows.
• Form 8938 for foreign financial assets above the higher thresholds that apply to people living abroad.
• PFICs: Dutch and other European mutual funds and ETFs are usually PFICs for US tax purposes, with punishing rules. Many Americans keep investments in US funds instead, which still count in Box 3.
• State taxes: some states keep taxing you after you move. Cut ties cleanly.

Both countries expect a return each year, so set calendar reminders: the Dutch return for 2026 is filed in the spring of 2027, and your US return by June 15, 2027, with an October extension available.

Questions about combining the two? Our community group for Americans in the Netherlands is a good place to compare notes, though for your own numbers, talk to a preparer who knows both systems.
