Tax-Free Investing in the USA: How German Investors Should Properly Tax US Returns
Tax-free investing in the USA means that income such as interest, dividends, or capital gains is partially or fully exempt from US federal income tax. For investors resident in Germany, there is a special feature: capital gains from US stocks remain tax-free in the USA and are taxed exclusively in Germany through capital gains tax. The double taxation agreement governs which country may tax which income.
What tax-free investing in the USA actually means
The term sounds more appealing than it is for German investors. In the USA, there are accounts and instruments whose income is permanently spared from federal tax. However, these tax advantages apply almost exclusively to persons with US tax obligations. Anyone living in Germany benefits only indirectly and must understand the local rules.
The distinction between genuine tax-free status and mere tax deferral is crucial. With a deferred account, taxation is only postponed. With a truly tax-free investment, no taxes are incurred on the income at any point, provided the conditions are met.
Tax-free versus tax-deferred
A tax-deferred account shifts the burden to the point of withdrawal. Tax-free accounts, on the other hand, allow gains to grow without the tax office intervening later. This distinction is the foundation of every tax-optimized investment strategy in the US system.
The most important tax-free investment vehicles in the USA
The US system has several accounts that offer genuine tax-free status. For German investors, they are usually not directly usable because contributions are tied to US income. Nevertheless, an overview is worth considering as guidance.
Roth IRA and the Roth IRA ETF
With a Roth IRA, savers contribute already-taxed income. Qualified withdrawals from age 59½ after at least five years of holding remain completely tax-free, including all capital gains. Many US investors hold broad index ETFs in a Roth IRA because their returns then remain untouched.
- Contribution limits 2026: $7,500 per year under age 50
- Age 50 and over: $8,500 including catch-up contribution
- Income limits: $168,000 for single filers, $252,000 for married couples filing jointly
- No required minimum distributions during lifetime
A Roth IRA ETF combines low-cost funds with tax-free compounding. For investors without US income, however, this model remains unavailable.
Municipal Bonds and tax-free interest
Municipal bonds finance roads, schools, or hospitals. Their interest is generally exempt from federal income tax. If an investor purchases bonds from their own state, state taxes are often waived as well. This makes these securities attractive for high-income taxpayers, even if the coupon rate is lower.
HSA and 529 Plans
Health Savings Accounts offer a triple advantage: deductible contributions, tax-free growth, and tax-free withdrawals for health expenses. 529 Plans work similarly for education expenses. Both instruments are suitable as components of a tax-optimized investment strategy, but remain tied to US tax obligations.
Do I have to pay taxes on stock gains from the USA?
The answer is clear for German investors. Capital gains from US stocks are tax-free in the USA for so-called nonresident aliens. Taxation occurs exclusively in Germany. There, capital gains tax of 25 percent applies, and together with solidarity surcharge, this amounts to 26.375 percent; with church tax, accordingly more.
For buying and selling US stocks, this means: the profit from rising prices is recorded at the German place of residence, not on the stock exchange in New York. The tax office treats these capital gains like domestic ones.
Foreign investments taxed domestically
The principle states: foreign investments taxed domestically. Anyone living in Germany pays tax on their worldwide income here. Gains from foreign stocks, funds, or bonds flow into the German tax return. This principle applies regardless of which country the account is held in.
The Double Taxation Agreement between Germany and the USA
The double taxation agreement between Germany and the USA prevents the same income from being taxed twice. It allocates taxation rights and determines how much withholding tax each country may retain.
Without this agreement, US dividends would be subject to 30 percent withholding tax. With the agreement, the rate drops to 15 percent. The German tax office credits these 15 percent against domestic capital gains tax, ensuring no double burden occurs.
Withholding tax on US dividends
Dividends from US stocks are initially subject to US withholding. Through the agreement, withholding tax is reduced to 15 percent. These are credited against German tax. In practice, the investor thus pays regular capital gains tax once, divided between both countries.
Taxation of mutual funds and ETFs
Mutual funds and ETFs in Germany are treated under the Investment Tax Act. Both distributing and accumulating funds are subject to advance accrued tax and a partial exemption, which exempts 30 percent of returns for equity funds from taxation.
For taxation purposes, it does not matter whether the fund invests in US securities or European securities. What matters is the legal form and equity share. A broadly diversified global ETF qualifies for the partial exemption and thus reduces the effective tax rate.
Is an ETF tax-free?
Keeping an ETF tax-free in Germany is only possible within the saver's exemption. This is €1,000 per person; for jointly assessed couples, €2,000. Up to this limit, capital gains from funds, stocks, and interest remain untaxed. Beyond this, capital gains tax applies.
Completely tax-free ETF returns exist only within a genuine tax-free US account like the Roth IRA, which is generally unavailable to German investors.
Tax considerations when selling ETFs
When selling, the investor realizes capital gains. The depository bank automatically deducts capital gains tax if a domestic account is used. Previously paid advance accrued taxes are offset to avoid double taxation.
Those trading through a foreign broker must report the gains themselves in their tax return. The tax rate remains the same; only the automatic withholding does not occur. A clear record of purchase price and sale proceeds is mandatory here.
Holding period and tax rate
Unlike in the USA, German tax law does not provide for reduced taxation after a twelve-month holding period. Every capital gain from stocks or ETFs is subject to the same capital gains tax, regardless of how long the securities were held.
Tax-optimized investment strategy for German investors
Tax-optimized investing begins with fully utilizing the saver's exemption. A tax exemption order with the bank ensures that the first €1,000 of capital gains per year remains untaxed.
Beyond that, several approaches are available to reduce the tax burden without breaking any rules.
- Split tax exemption orders across multiple banks
- Use accumulating equity ETFs with 30 percent partial exemption
- Strategically use losses for offset
- Involve spouse to double the exemption amount
Diversification and investment strategy
Thoughtful diversification across stocks, bonds, real estate funds, and commodities like gold reduces risk and distributes tax effects. Gold, for example, remains tax-free after a one-year holding period in private assets, an advantage that physical funds or cryptocurrencies cannot offer in the same way.
With cryptocurrencies like Bitcoin, tax-free treatment of private capital gains also applies after a twelve-month holding period. A swap of Bitcoin for another currency is considered a sale. This feature distinguishes digital assets significantly from stocks, where every gain is subject to tax.
Offsetting losses
Losses from securities transactions can be offset against gains. German tax law separates loss buckets here: losses from stocks may only be offset against gains from stocks, while other capital income flows into a separate bucket.
The bank handles these buckets automatically. Those using multiple accounts can request a loss certificate and claim losses in their tax return. This way, realized losses reduce taxes on other gains.
Practical handling of losses
Realized losses at year-end can significantly reduce tax liability. Those who sell positions with book losses and repurchase similar securities benefit from this effect without fundamentally changing their investment strategy. For larger amounts, it is worthwhile to consult with a tax advisor.
Special cases for US investments
Not all US income is tax-free for foreigners. US real estate sales are subject to the FIRPTA regime, which subjects nonresidents to US tax. Anyone investing in US real estate or related companies must pay attention to this exception.
Additionally, there is the Net Investment Income Tax of 3.8 percent on passive income, which primarily affects US taxpayers with higher incomes. For German investors without US tax obligations, it is generally irrelevant.
PFIC regulation and Section 899
The Passive Foreign Investment Company rule affects US taxpayers investing in non-US funds. Such investments are subject to disadvantageous taxation, which is why US persons should avoid European ETFs. Conversely, the PFIC rule is irrelevant for pure German taxpayers. The discussed Section 899 targets investors from countries with taxes classified as discriminatory and could influence future withholding taxes.
Practical steps for getting started
Those who want to add US stocks or ETFs to their portfolio should consider the tax treatment from the outset. A domestic account simplifies handling because the bank automatically accounts for taxes and withholding tax.
- Set up a tax exemption order for €1,000
- For US dividends, submit Form W-8BEN to reduce withholding tax to 15 percent
- Choose accumulating ETFs for the compounding effect
- Keep track of loss buckets and review at year-end
- Consult professional advice for cross-border issues
When professional advice is worthwhile
For simple investments, a tax exemption order and automatic tax deduction suffice. It becomes more complex with foreign accounts, dual residency, or larger real estate investments. Here, a specialized tax advisor clarifies which contracts and evidence the tax office requires.
Conclusion on tax-free investing in the USA
For German investors, tax-free investing in the USA is less a goal than a misconception. Genuine tax-free status through Roth IRA or Municipal Bonds remains tied to US tax obligations. What German investors have is the smart use of domestic advantages.
The conclusion is clear: capital gains from US stocks remain tax-free in the USA but are taxed in Germany. Those who consistently use the saver's exemption, partial exemption, and loss offsetting practice effective tax-optimized investing, all legally and without complicated foreign structures.
