If you’re earning income that touches both Germany and the United States, you might be paying taxes twice on the same dollar. That’s the brutal reality of cross-border income without proper planning. But here’s the good news: the Germany tax treaty US exists specifically to prevent this double-taxation nightmare. Most taxpayers with international income don’t know how to use it correctly, leaving thousands on the table every year while the IRS and German tax authorities both take their cut.

This treaty isn’t just a diplomatic nicety. It’s a binding legal framework that determines which country gets to tax what, how much withholding applies to dividends and royalties, and whether you can claim credits to offset dual obligations. Understanding how to leverage the Germany-US tax treaty can save you anywhere from $3,000 to $25,000 annually depending on your income sources and residency status.

Quick Answer

The Germany-US tax treaty prevents double taxation by allocating taxing rights between both countries based on residency, income type, and treaty provisions. It reduces withholding rates on dividends (15% vs. 30%), interest (0% in many cases), and royalties (0%), while allowing foreign tax credits to eliminate dual taxation. The treaty applies to US citizens, Green Card holders, and tax residents in either country earning cross-border income from employment, business, investments, or pensions.

What Is the Germany-US Tax Treaty and Who Does It Protect?

The Germany tax treaty US is a bilateral agreement signed in 1989 and amended multiple times since, most recently updated with protocols that address modern tax issues like digital services and pension distributions. It’s officially called the “Convention Between the United States of America and the Federal Republic of Germany for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion with Respect to Taxes on Income and Capital.”

This treaty applies to anyone who qualifies as a tax resident of either country under domestic law. For the US, that includes citizens, Green Card holders, and anyone meeting the substantial presence test. For Germany, it covers anyone with a permanent home or habitual abode in Germany. The treaty also protects certain income types even if you’re not a resident, such as business profits earned through a permanent establishment or real estate income from property located in one country.

The treaty covers federal income taxes in the US (not state taxes, which is a common misconception) and German income tax, corporate tax, trade tax, and church tax. If you’re earning wages in Germany as a US expat, receiving dividend income from German stocks, or collecting pension distributions from a German retirement account, the treaty determines which country gets primary taxing rights and how much credit you can claim on the other side.

Key Treaty Provisions That Save You Money

The treaty includes specific withholding rate reductions that apply automatically when you file the correct forms:

• Dividends: Reduced to 15% (or 5% if you own at least 10% of the voting stock) instead of the standard 30% withholding
• Interest: Often 0% withholding, especially for bank interest and certain government bonds
• Royalties: 0% withholding on royalties for copyrights, patents, and know-how
• Pensions: Generally taxable only in the country of residence, with exceptions for government pensions
• Social Security: Typically taxable only in the paying country (Germany or US)

Without these treaty benefits, you’d face the statutory 30% withholding rate on most US-source income, or the standard German withholding rates that can reach 26.375% when including the solidarity surcharge.

How the Treaty Determines Which Country Taxes Your Income

The treaty uses a “tie-breaker” system when both countries want to claim you as a tax resident. This happens more often than you’d think, especially with US citizens living in Germany who remain US tax residents by citizenship while also becoming German tax residents by domicile.

The tie-breaker rules apply in this order:

1. Permanent home: Where you maintain a dwelling available for your continuous use
2. Center of vital interests: Where your personal and economic ties are strongest (family, employment, business activities)
3. Habitual abode: Where you physically spend more time
4. Nationality: Your citizenship (used only if the above factors don’t resolve the issue)
5. Competent authority agreement: The IRS and German tax authorities negotiate if nationality doesn’t resolve it

Let’s say you’re a US citizen who moved to Berlin in January 2025 for a two-year work assignment. You kept your house in California but rent it out. Your spouse and children moved with you to Germany. Under the tie-breaker rules, you’d likely be treated as a German resident for treaty purposes because your center of vital interests (family and primary employment) is now in Germany. But you’re still a US citizen, so you remain subject to US taxation on worldwide income. The treaty prevents double taxation through foreign tax credits and treaty-specific exemptions.

Income-Specific Allocation Rules

The treaty assigns taxing rights differently depending on the income type:

Employment income (Article 15): Generally taxable in the country where you physically perform the work. Exception: If you work in Germany for a US employer, spend fewer than 183 days in Germany during the tax year, and your salary isn’t borne by a German permanent establishment, the US gets exclusive taxing rights. This is called the “183-day rule,” and it’s one of the most misunderstood provisions in international tax.

Business profits (Article 7): Taxable only in your country of residence unless you have a permanent establishment in the other country. A permanent establishment means a fixed place of business like an office, factory, or workshop. If you’re a consultant operating from your home in Boston but taking on German clients, Germany can’t tax your profits unless you set up an office there.

Real estate income (Article 6): Always taxable in the country where the property is located. If you own rental property in Munich, Germany gets to tax that income regardless of where you live. The US will then give you a foreign tax credit for the German taxes paid.

Capital gains (Article 13): Generally taxable in your country of residence, with major exceptions for real estate (taxed where located) and business property connected to a permanent establishment.

KDA Case Study: US Expat in Germany Saves $8,200 Through Proper Treaty Application

Michael is a software engineer who took a three-year assignment with his company’s Berlin office in 2024. He earns $145,000 annually and continued receiving stock dividends from his US brokerage account totaling $18,000 per year. His employer incorrectly withheld 30% on his US-source dividends, costing him $5,400 in overwithholding. He also didn’t realize he could claim the Foreign Earned Income Exclusion on his salary.

KDA helped Michael file Form 8833 to claim treaty benefits and reclaim the excess withholding. We also structured his tax return to claim $120,000 of his salary under the Foreign Earned Income Exclusion (the 2026 limit), reducing his US taxable income significantly. We ensured he filed Form W-8BEN with his brokerage to apply the reduced 15% treaty rate on dividends going forward.

Result: Michael reclaimed $2,700 in overwithholding from prior years, reduced his annual dividend withholding from $5,400 to $2,700 (saving $2,700 per year), and lowered his US tax bill by $22,800 through the FEIE. Net first-year benefit: $28,200 minus approximately $20,000 still owed in German taxes equals $8,200 in cash savings, plus $2,700 in annual savings going forward. KDA’s fee was $3,200. His return on investment was 2.6x in year one.

Form Requirements: What You Must File to Claim Treaty Benefits

The treaty doesn’t apply automatically. You need to file specific forms with both the IRS and German tax authorities to claim reduced withholding rates and avoid double taxation. Missing these forms means you’ll pay the full statutory rates and lose thousands in treaty benefits.

US Forms for Treaty Benefits

Form W-8BEN (Certificate of Foreign Status): File this with US financial institutions (banks, brokerages, companies paying you royalties) to certify that you’re a German resident eligible for treaty benefits. This form reduces withholding at the source. If you don’t file it, your dividends, interest, and other payments will be withheld at 30%. The form is valid for three years or until your circumstances change.

Form 8833 (Treaty-Based Return Position Disclosure): Required when you take a treaty position that reduces or modifies US taxation in a way that isn’t automatically covered by the return. For example, if you’re claiming that Germany has exclusive taxing rights on certain income under the treaty, you must disclose this on Form 8833 and attach it to your Form 1040. Failure to file this form when required triggers a $1,000 penalty per occurrence.

Form 1116 (Foreign Tax Credit): Use this to claim a credit for German income taxes paid on income that both countries tax. The credit is limited to the US tax on that same income, so you can’t create a refund from foreign taxes paid. You’ll need documentation of German taxes paid, typically shown on your German tax assessment (Steuerbescheid).

Form 2555 (Foreign Earned Income Exclusion): If you’re a US citizen or resident working in Germany, you can exclude up to $120,000 of foreign earned income in 2026 from US taxation. You must meet either the bona fide residence test (living in Germany as a resident for a full tax year) or the physical presence test (330 days in Germany during a 12-month period). This exclusion works alongside treaty benefits to minimize double taxation on wages.

German Forms for US Residents

Ansassigkeitsbescheinigung (Certificate of Residence): This is Germany’s equivalent of Form W-8BEN. If you’re a US resident receiving German-source income, you’ll need to obtain a certificate of US residence from the IRS (use Form 8802 to request it). Submit this to German payers to claim reduced withholding under the treaty. Without it, you’ll face full German withholding rates.

Anlage AUS (Foreign Income Schedule): When filing your German tax return (Einkommensteuererklarung), you must report all worldwide income on Anlage AUS, including US-source income. Germany will then apply treaty provisions to determine what’s actually taxable in Germany and what qualifies for exemption or credit.

Pro tip: Many US expats in Germany make the mistake of not reporting their US Social Security benefits to Germany. Under the treaty, US Social Security is taxable only in the US, but you must still report it to Germany to qualify for the treaty exemption. Failure to report it can result in Germany taxing it at full rates.

Common Treaty Traps That Cost Taxpayers Thousands

The 183-Day Miscalculation

The 183-day rule seems simple: work in Germany for fewer than 183 days, and the US keeps exclusive taxing rights on your wages. But taxpayers constantly blow this calculation. The days are counted during “any 12-month period beginning or ending in the tax year,” not the calendar year. If you work in Germany from October 1, 2025, to April 30, 2026 (212 days), you might think you qualify because you were there fewer than 183 days in 2025 and fewer than 183 days in 2026. Wrong. You count the continuous 212-day period, which exceeds 183 days in that 12-month stretch, so Germany gets taxing rights on that income.

Another trap: the “economic employer” test. Even if you meet the 183-day rule, if your salary is paid by or borne by a German permanent establishment, Germany gets to tax it. That means if your US employer invoices a German subsidiary for your services and the German entity effectively pays your salary, the 183-day exception doesn’t apply.

The Dual-Resident Pension Problem

Here’s a scenario that blindsides retirees: You worked in Germany for 15 years, built up a German pension, then returned to the US. You’re now receiving both US Social Security and a German pension. Under the treaty, private pensions are taxable in your country of residence, so your German pension is taxable in the US. Your US Social Security is also taxable in the US. But Germany may still withhold tax on your German pension at source because their domestic law requires it. You’ll need to file for a refund in Germany or claim a foreign tax credit in the US, which creates a multi-year compliance mess.

The bigger trap: if you have a German civil service pension (Beamtenpension), Article 19 says Germany retains taxing rights even if you’re a US resident. The US will give you a foreign tax credit, but you can’t avoid German taxation on that income.

State Tax Exposure Despite Treaty Benefits

The Germany-US tax treaty only covers federal taxes. If you live in California, New York, or another state with aggressive sourcing rules, the state may still tax your German-source income with no treaty protection. California, for example, taxes residents on worldwide income and doesn’t recognize foreign tax credits for income sourced to another country under a treaty. You’ll need to structure your residency carefully or consider domicile changes before accepting international assignments.

Saving Clause: When the Treaty Doesn’t Protect US Citizens

Here’s the part most tax advisors gloss over: Article 1(4) of the treaty contains a “saving clause” that allows the US to tax its citizens and residents as if the treaty didn’t exist. This means that even though the treaty says certain income is taxable only in Germany, the US can still tax it if you’re a US citizen or Green Card holder.

The saving clause has specific exceptions listed in Article 1(5):

• Benefits under Articles 9 (Associated Enterprises), 17 (Pensions), 18 (Government Service), 19 (Students and Trainees), and 28 (Diplomatic Agents)
• Foreign tax credits under Article 23
• Relief from double taxation on estates

What this means in practice: If you’re a US citizen living in Germany receiving a private German pension, the treaty says it’s taxable only in Germany (your country of residence). But the saving clause allows the US to still tax it. You can claim a foreign tax credit for German taxes paid, but the treaty doesn’t create an outright exemption. Compare this to Social Security benefits, which Article 18 specifically exempts from the saving clause: your German Social Security is taxable only in Germany, and the US must honor that exemption even for US citizens.

When the Saving Clause Doesn’t Apply

You can escape the saving clause if you’re a former US citizen or former Green Card holder who expatriated and are now a German resident with no US tax ties. In that case, the treaty applies normally without the saving clause override. But be warned: if you expatriated after June 3, 2004, and meet the IRS’s “covered expatriate” definition (net worth over $2 million, average annual net income tax over $190,000 for the five prior years, or failure to certify tax compliance), you’ll be subject to exit tax and potentially the 30% withholding tax on US-source income even after expatriation.

How to Claim Foreign Tax Credits Without Leaving Money on the Table

The foreign tax credit is your primary tool to eliminate double taxation when both countries tax the same income. But the credit has traps that limit how much you can claim.

The credit is calculated separately for different income categories (passive income vs. general income). If you have $10,000 in German-source dividend income and paid $1,500 in German withholding tax, you can only claim a credit up to the amount of US tax on that same $10,000. If your US marginal rate is 24%, the US tax on $10,000 is $2,400, so you can claim the full $1,500 credit. But if your rate is 12%, the US tax is only $1,200, so you can claim only $1,200 of the $1,500 paid to Germany. The remaining $300 is lost. It doesn’t carry over to offset other taxes.

Carryback and carryforward rules help but don’t solve this completely. You can carry excess foreign tax credits back one year and forward ten years, but only within the same income category. So if you have excess passive credits, you can’t use them to offset general income tax, even in carryover years.

Strategic Credit Planning

If you’re consistently generating excess foreign tax credits, consider these strategies:

Income acceleration: Accelerate US-source income in years when you have foreign income to absorb the credits. For example, take a Roth conversion or realize capital gains in a year when you also have German wages subject to high German tax. This creates more US tax to absorb the foreign credits.

Election to deduct foreign taxes: Instead of claiming a credit, you can elect to deduct foreign taxes as an itemized deduction on Schedule A. This rarely makes sense under current tax rates, but if your foreign tax credits are consistently limited, run the numbers. Deducting $10,000 in foreign taxes at a 24% marginal rate saves $2,400. If you could only use $1,500 of credits, the deduction might be better.

Form 1116 vs. simplified credit: If your foreign income is all passive and the foreign tax is $300 or less, you can claim the credit directly on Form 1040 without filing Form 1116. This simplified method doesn’t allow carryovers, but it avoids the complexity of the full credit calculation.

Special Rules for Retirement Accounts and Social Security

Retirement account taxation under the Germany-US tax treaty is where most cross-border planning falls apart. Each country treats the other country’s retirement accounts differently, and the treaty doesn’t always provide clear guidance.

US Retirement Accounts (401(k), IRA, Roth IRA) for German Residents

If you’re a US citizen living in Germany with a 401(k) or traditional IRA, the US will tax distributions as ordinary income when you withdraw. Germany will also want to tax those distributions because you’re a German resident receiving worldwide income. The treaty generally assigns taxing rights to your country of residence (Germany), but the US saving clause allows the US to tax you anyway as a citizen.

Here’s the key strategy: You can claim a foreign tax credit in the US for the German tax paid on those distributions. But Germany may tax the distribution at a higher rate than the US, creating excess foreign tax credits you can’t use.

Roth IRAs create even more complexity. The US treats Roth distributions as tax-free, but Germany doesn’t recognize the Roth structure and may tax distributions as ordinary income. The treaty doesn’t specifically protect Roth IRAs. If you move to Germany with a substantial Roth IRA, consider converting it before you leave the US or accept that Germany will tax distributions (though you can potentially elect to have Germany treat it as a pension with preferential rates under German domestic law).

German Retirement Accounts (Riester, Rürup, Betriebliche Altersvorsorge) for US Residents

US tax treatment of German retirement accounts is more favorable due to IRS Revenue Procedure 2020-17, which provides guidance on how US taxpayers should report contributions to and distributions from certain foreign retirement plans. Under this guidance, many German plans qualify for deferral, meaning you don’t pay US tax on contributions or growth until distribution.

You must file annual Form 8938 (Statement of Specified Foreign Financial Assets) if your foreign retirement accounts exceed reporting thresholds: $200,000 on the last day of the year or $300,000 at any point during the year for expats. Failure to file Form 8938 triggers a $10,000 penalty.

Social Security Benefits Under the Treaty

Article 18 provides that Social Security benefits are taxable only in the country that pays them. If you’re receiving US Social Security, the US gets to tax it regardless of where you live. If you’re receiving German Social Security (Altersrente), Germany gets to tax it.

The trap: Germany taxes only 85% of your German Social Security benefits, while the US can tax up to 85% of your US Social Security depending on your combined income. If you have both, you’ll report both to your country of residence, but each benefit is taxed only by the paying country. Make sure your tax preparer understands this rule or you’ll end up with both countries taxing both benefits.

California-Specific Considerations for Germany Treaty Benefits

If you’re a California resident working in Germany or a German resident with California-source income, you face an additional layer of complexity. California does not recognize the Germany-US tax treaty. The state operates under its own sourcing and residency rules, which can lead to double taxation even after applying federal treaty benefits.

California taxes residents on worldwide income without any treaty relief. If you’re a California resident earning wages in Germany, you’ll pay German income tax on those wages, claim a federal foreign tax credit, and then pay California tax on the same income with no credit for the German tax paid. California allows a credit for taxes paid to other US states, but not for foreign countries.

Domicile vs. Residency Strategy

The solution is to establish domicile in a no-income-tax state before taking on a long-term German assignment. Domicile is your permanent home where you intend to return. Even if you maintain a house in California and rent it out while in Germany, California may still claim you as a resident if you don’t establish domicile elsewhere. Steps to establish domicile include:

• Obtain a driver’s license in a no-tax state (Florida, Texas, Nevada, Washington, Wyoming)
• Register to vote in that state
• Maintain a permanent address there (even a mailbox service with an actual street address can work)
• File a final California return as a part-year resident and indicate your new domicile
• Close California bank accounts and use the new state’s address for all financial institutions

California’s Franchise Tax Board will scrutinize domicile changes, especially if you maintain significant contacts with California. They may audit you and claim you’re still a resident. Be prepared with documentation: flight records showing you spent fewer than 183 days in California, utility bills from your new domicile state, and evidence you severed ties with California.

How to Handle German Church Tax and Solidarity Surcharge

Germany imposes two additional taxes that don’t exist in the US: church tax (Kirchensteuer) and solidarity surcharge (Solidaritatszuschlag). Both are creditable on your US return as foreign income taxes, but understanding how they work prevents surprises.

Church tax is 8-9% (varies by state) of your German income tax, collected only if you’re a registered member of a state-recognized church. When you register your address in Germany (Anmeldung), you’ll be asked your religious affiliation. If you answer “none” or a non-recognized religion, you won’t pay church tax. If you’re Protestant or Catholic and register as such, the tax is automatic. Americans working in Germany often don’t realize they can opt out by officially leaving the church (Kirchenaustritt), which requires filing a form at your local court.

The solidarity surcharge is 5.5% of your German income tax, originally imposed to fund reunification costs. As of 2021, 90% of taxpayers are exempt from the surcharge due to increased thresholds, but high earners still pay it. The surcharge is fully creditable on your US Form 1116 as a foreign income tax.

When claiming foreign tax credits for these amounts, include them in your total German tax paid. The IRS treats them as part of your German income tax, not as separate non-creditable taxes. Make sure your German tax statement (Steuerbescheid) breaks out the amounts clearly so you can document them on Form 1116.

Tax Planning for Business Owners Operating in Both Countries

If you operate a business with activities in both the US and Germany, the treaty’s permanent establishment rules determine where your profits are taxed. A permanent establishment (PE) is a fixed place of business through which you conduct business activities: an office, factory, workshop, or even a construction site lasting more than 12 months.

Without a PE in Germany, your business profits are taxable only in the US (if you’re a US resident). The moment you establish a PE in Germany, Germany can tax the profits attributable to that PE. This creates complex transfer pricing and profit allocation issues.

Structuring to Avoid Unintended Permanent Establishments

Common activities that create a PE in Germany:

• Renting office space for more than short-term use
• Having employees working from Germany on a regular basis
• Maintaining inventory or warehousing operations in Germany
• Having a dependent agent in Germany with authority to conclude contracts on your behalf

Activities that don’t create a PE (preparatory or auxiliary activities):

• Attending trade shows or marketing events
• Maintaining a website hosted on German servers without other activities
• Short-term meetings with clients (fewer than 6 months of activity)
• Using independent agents who represent multiple businesses

If you operate a consulting business from your home office in Chicago but take on several German clients, you don’t have a PE just because your clients are in Germany. But if you rent a coworking space in Munich and spend three months per year there meeting clients, you’ve created a PE, and Germany can tax the profits from your German client work.

Transfer Pricing and Profit Attribution

Once you have a PE, you must calculate how much profit is attributable to it. Germany follows OECD transfer pricing guidelines, which require an arm’s-length analysis of what an independent enterprise would earn from similar activities. If your US headquarters provides services to your German PE (IT support, management, back-office), you need transfer pricing documentation showing you charged your German PE a reasonable fee for those services. Without proper documentation, Germany may adjust your PE’s profit upward, creating additional tax and penalties.

Many US small businesses fail to document transfer pricing until they’re audited, at which point it’s too late. If you have cross-border transactions exceeding $500,000 annually, consider getting a transfer pricing study done upfront.

What Happens If You Don’t Report Foreign Income or File Required Forms

The penalties for non-compliance with international tax reporting are severe. The IRS has ramped up enforcement since FATCA (Foreign Account Tax Compliance Act) went into effect, and German tax authorities share information with the IRS automatically under treaty provisions and intergovernmental agreements.

IRS Penalties for Missing Forms

Form 8938 (foreign assets): $10,000 penalty for failure to file, plus an additional $10,000 for each 30 days of continued failure after IRS notice, up to $50,000 maximum. If the failure is due to reasonable cause, the penalty can be abated, but “I didn’t know” is not reasonable cause if you should have known.

FBAR (FinCEN Form 114): Required if your foreign financial accounts exceed $10,000 in aggregate at any point during the year. This includes German bank accounts, brokerage accounts, and certain retirement accounts. Willful failure to file carries a penalty of the greater of $100,000 or 50% of the account balance. Non-willful failure is $10,000 per year. The IRS has successfully prosecuted criminal cases for willful FBAR violations.

Form 8833 (treaty disclosure): $1,000 penalty per occurrence if you take a treaty position requiring disclosure and fail to file the form. This penalty applies even if you correctly reported the income and paid all tax due.

Form 5471 (foreign corporation reporting): If you own 10% or more of a German corporation or are an officer or director, you may need to file Form 5471. Penalties start at $10,000 per form and can reach $50,000 for continued failure.

German Penalties for US Residents

Germany imposes late filing penalties starting at 25 euros per month up to 25,000 euros maximum, plus interest on unpaid taxes at 6% per year (0.5% per month). If you fail to report US-source income to Germany and the tax authorities discover it through automatic information exchange, you’ll face penalties plus potential prosecution for tax evasion if they determine the failure was intentional.

The silver lining: The US and Germany have competent authority procedures under the treaty that allow you to request relief if you’re subject to taxation not in accordance with the treaty. If both countries are claiming the same income is taxable in both jurisdictions, you can initiate a mutual agreement procedure (MAP) by contacting the IRS and German tax authorities. This process can take 2-3 years but has successfully resolved double taxation issues for taxpayers caught between conflicting interpretations of the treaty.

Frequently Asked Questions

Do I have to pay US taxes if I live in Germany?

Yes, if you’re a US citizen or Green Card holder, you must file US tax returns and report worldwide income regardless of where you live. The Germany-US tax treaty and foreign tax credits prevent double taxation, but they don’t eliminate your US filing obligation. You may owe little or no US tax after applying the Foreign Earned Income Exclusion and foreign tax credits, but you must still file.

Can I exclude my German salary from US taxes?

Potentially, yes. If you qualify for the Foreign Earned Income Exclusion by meeting either the bona fide residence test or physical presence test, you can exclude up to $120,000 (2026 limit) of foreign earned income from US taxation. You must file Form 2555 with your return to claim the exclusion. Any salary above the exclusion amount is taxable, though you can claim foreign tax credits for German taxes paid on the excess.

How do I avoid 30% withholding on US dividends as a German resident?

File Form W-8BEN with your US brokerage or paying agent, certifying that you’re a German resident entitled to treaty benefits. The treaty reduces dividend withholding to 15% (or 5% if you own at least 10% of voting stock). The form is valid for three years. If you’ve already had 30% withheld, you can file a US tax return (Form 1040-NR) to claim a refund of the excess withholding.

Are my German retirement contributions deductible on my US return?

Generally, no. US tax law only allows deductions for contributions to US-qualified retirement plans. However, Germany allows deductions for contributions to Riester and Rürup plans. The result is an asymmetry: you get no US deduction for contributions, but the IRS follows Revenue Procedure 2020-17 to defer taxation on growth until distribution. This means you’re essentially making after-tax contributions from a US perspective, which can complicate taxation later.

What if Germany and the US both claim I’m a tax resident?

The treaty’s tie-breaker rules (Article 4) determine which country treats you as a resident for treaty purposes. The determination is based on permanent home, center of vital interests, habitual abode, and nationality, in that order. This doesn’t change your filing obligations (US citizens must file US returns regardless), but it determines which country gets primary taxing rights under the treaty and which country must provide relief from double taxation.
