Heirs Facing German Inheritance Tax on Cross-border Estates

Heirs or legatees facing German inheritance tax cross-border situations often discover that a single German asset, a holiday apartment or a shareholding can draw part of a succession into Germany’s tax net. German inheritance tax (Erbschaftsteuer) applies to far more people than most beneficiaries expect, because liability can be triggered by the residence of the deceased, the residence of the heir or legatee, or simply the location of an asset. For families spread across borders, the practical challenge is not only calculating the tax but acting quickly enough to preserve reliefs and avoid penalties.

This guide explains, in plain English and with references to German primary law, when Germany taxes a succession, how the tax is assessed, how double taxation treaties interact, and what heirs/legatees and executors should do immediately.

Introduction, what cross-border heirs must know

The transfer of an estate on death is governed in Germany by the Bürgerliches Gesetzbuch (BGB), the Civil Code. The estate passes automatically  to the heirs as a whole at the moment of death (the principle of universal succession). The universal succession happens either pursuant to the last will of the deceased of – if missing – pursuant to statutory laws. This automatic transfer matters for tax liability for German inheritance tax crystallises on the date of death, and the clock on reporting obligations starts running from the point the heir learns of the inheritance.

Before diving into detail, heirs facing German inheritance tax cross-border issues should keep a short orientation checklist in mind:

• Check the connecting factors. Was the deceased resident in Germany? Is the heir/legatee resident in Germany? Are any assets located in Germany? Any one of these can create liability.
• Identify the German-situs assets. Real estate, business assets and substantial shareholdings in German companies are the most common triggers.
• Note the reporting duty. Acquisitions subject to inheritance tax must be notified to the German tax office, and timelines are short.
• Gather valuation evidence early. Values are fixed as of the date of death, so contemporaneous documentation is essential.
• Consider treaty relief. If another country also taxes the estate, a credit or exemption may be available.

The core rules on who is taxable, which assets are caught, and which reliefs apply are set out in the Erbschaftsteuer- und Schenkungsteuergesetz (ErbStG), the Inheritance and Gift Tax Act.

Who is taxable in Germany? Unlimited vs limited tax liability

The threshold question for anyone dealing with German inheritance tax is whether unlimited or limited tax liability applies. The distinction, set out in ErbStG §2, determines whether Germany taxes the worldwide estate or only German-situated assets. This is the single most important concept for heirs facing German inheritance tax cross-border exposure, because it defines the scope of the tax before any reliefs or treaties are considered.

Unlimited tax liability (residents)

Unlimited tax liability (unbeschränkte Steuerpflicht) arises where either the deceased or the heir/legatee is a German resident, technically, an Inländer (a person with residence or habitual abode in Germany) at the time the tax arises. Where unlimited tax liability applies, Germany taxes the entire estate worldwide, not merely the German portion. Residence for these purposes follows the general residency concepts of the Abgabenordnung (AO), the Fiscal Code, which look to where a person has a dwelling they can use and retain, or where they are habitually present. German nationals who have given up German residence may in certain circumstances remain within unlimited liability for a defined period; the detailed rules are in the ErbStG.

A practical consequence: if an heir/legatee living in Germany inherits from a parent who lived abroad, this draw the whole foreign estate into German inheritance tax. Residence is therefore not a matter the deceased alone controls, the beneficiary’s own status is decisive, too.

Limited tax liability (non-residents)

Where neither the deceased nor the heir or legatee is a German resident, only limited tax liability (beschränkte Steuerpflicht) or extended limited tax liability (erweitert beschränkte Steuerpflicht) arises. In case of limited tax liability Germany taxes only the assets that qualify as Inlandsvermögen, German domestic property, as defined in the ErbStG (which adopts the definition in the Valuation Act, Bewertungsgesetz). This category is narrower than “any asset connected to Germany”: it targets specific asset types with a clear German nexus, such as German real estate, German business assets and substantial shareholdings in German corporations.

Two illustrative examples show how this works in practice for heirs facing German inheritance tax cross-border facts:

• A UK-resident heir inherits a German apartment. Neither party is a German resident, so limited liability applies. Germany taxes the German real estate, but not the heir’s inherited UK assets.
• A US-resident heir inherits shares in a German corporation. Whether the shareholding falls within German domestic property depends on the size of the shareholding and the statutory nexus test, significant participations in German companies can be caught even where the shareholder never set foot in Germany.

Because the residency and nexus tests carry a real evidentiary burden, heirs/legatees should document the deceased’s and their own residence position carefully. The German courts, including the Bundesfinanzhof (BFH), the Federal Fiscal Court, regularly adjudicate residency and nexus questions, and the outcome can change the tax base dramatically.

In case of the extended limited inheritance tax liability (as set out in AStG §4), additonal assets will become subject to German inheritance tax. The extended limited inheritance tax liability applies, if the deceased was subject to German unlimited income tax liability for five years within the last 10 years before his/her death and moved to a low-tax jurisdiction while keeping significant economic interests in Germany; the extended limited income tax liability applies for ten years after the individual’s German tax residency was terminated. Thus, the extended limited inheritance tax liability applies also in case of death within ten years after the deceased has terminated his/her tax residency in Germany.

Which assets are subject to German inheritance tax (situs rules)

Under limited inheritance tax liability, the decisive issue is which assets count as German domestic property. The ErbStG, read together with the Valuation Act, sets out the categories, and understanding them is essential for any analysis of German inheritance tax on a cross-border estate.

Real estate located in Germany

German land and buildings are the clearest case of German domestic property. Real estate situated in Germany is taxable regardless of the residence of the deceased or the heir/legatee. This is why so many cross-border estates become German tax matters: a single property in Germany is sufficient to trigger a filing and an assessment.

Business assets and permanent establishments

Business assets of a German trade or business, in particular assets attributable to a German permanent establishment (Betriebsstätte), are also treated as German domestic property. An heir/legatee who inherits an interest in a business operating in Germany, or assets dedicated to a German permanent establishment, will generally face German inheritance tax on that interest even under limited liability.

Shares in German corporations

Shareholdings in German corporations can be German domestic property where the participation meets the statutory threshold for a substantial holding. The nexus rule here turns on the size of the stake rather than on where the shares are held or administered. A modest portfolio holding may fall outside the net, while a significant participation in a German corporation is likely to be caught; a significant participation would be a direct/indirect shareholding of at least 10% held either alone or together with affiliated parties in a corporation. Heirs/legatees should confirm the current statutory participation threshold in the applicable legislation.

Worked example: A non-resident heir/legatee inherits a German commercial building and a 30% stake in a German operating corporation. The building is German domestic property and plainly taxable. The corporation stake must be tested against the statutory participation threshold; as it qualifies, both assets form the German tax base, and reliefs for business property (discussed below) may become relevant.

Under extended limited liability, additionally all asset whose income was subject to the extended limited income taxation will become subject to German inheritance tax, too. 

Liability and who must file: heirs, legatees executors and administrators

A frequent point of confusion for heirs/legatees facing German inheritance tax cross-border situations is whether the tax falls on the estate or on the individual beneficiary. German inheritance tax is, in substance, a tax on the acquisition by the recipient, it is the heir (or legatee, or other beneficiary) who is the taxable person for their share of the estate.

Who is assessed and who must notify

Because the tax attaches to the acquisition, each heir is assessed on what they receive. The practical duties, however, extend further. Beneficiaries are required to notify the competent German tax office of their acquisition, and this notification obligation is independent of whether a full return is later requested. In addition, certain third parties, banks, insurers and others holding assets of the deceased, have their own notification duties to the tax authorities. Where an executor or estate administrator is appointed, that representative typically plays a central role in gathering information and in dealing with the tax office.

The procedural framework for notification, assessment and payment is governed by the Abgabenordnung together with the ErbStG. The practical rule for heirs is simple: do not assume someone else will report the inheritance. The duty to notify rests, in the first instance, on the person who acquires.

Mutual assistance for non-resident heirs

Non-resident heirs/legatees sometimes assume that distance insulates them from German assessment. It does not. The Bundeszentralamt für Steuern (BZSt), the Federal Central Tax Office, administers cross-border information exchange and administrative assistance, and German tax authorities can obtain information and pursue assessments in respect of German-situs assets regardless of where the heir/legatee lives. A non-resident who inherits German property should expect the German tax office to engage, and should respond through the proper administrative channels rather than ignore correspondence.

Valuation: how German law values inherited assets

Once the taxable base is identified, the next step is valuation. German inheritance tax is charged on value as at the date of death, and the ErbStG, together with the Valuation Act (Bewertungsgesetz), governs how each asset class is measured. Accurate, well-evidenced valuation is often where the most tax is won or lost for heirs/legatees facing German inheritance tax cross-border assessments.

Real estate valuation

German real estate is valued broadly by reference to market value (gemeiner Wert), applying the statutory valuation methods for different property types set out in the Valuation Act. The valuation can be significant in amount, and where the statutory method produces a figure the heir considers too high, it is generally possible to demonstrate a lower market value with appropriate expert evidence. Because the relevant date is the date of death, obtaining a qualified appraisal that reflects conditions at that point is important.

Business valuation and goodwill

Inherited business assets and company shares are valued on the basis of their fair market value, which for operating businesses requires an assessment that captures substance and, where relevant, goodwill. Business valuation is technically demanding and frequently contested, and it interacts closely with the business succession reliefs discussed below. Early professional valuation is advisable both to fix the base and to position any relief claim.

Securities and foreign assets

Listed securities are generally valued at their market price on the valuation date. Where the estate includes foreign-currency assets, amounts must be converted into euros using the appropriate exchange rate as at the relevant date. For cross-border estates, consistent treatment of foreign assets, foreign-currency conversion and the valuation date is essential to avoid disputes.

Evidence checklist for valuations:

• Independent appraisal of German real estate as at the date of death.
• Business accounts, balance sheets and a professional business valuation for company interests.
• Broker or exchange statements evidencing securities prices on the valuation date.
• Documentation of exchange rates applied to foreign-currency assets.
• Records of debts and liabilities deductible from the estate.

Tax classes, allowances and reliefs for heirs/legatees facing German inheritance tax cross-border estates

German inheritance tax is not a flat charge. The amount payable depends on the relationship between the deceased and the heir/legatee, which determines the tax class, the personal allowance and the applicable rate band. These rules, set out in the ErbStG, apply equally to cross-border cases, so heirs/legatees facing German inheritance tax cross-border liability need to identify their class and allowance before estimating any liability.

Tax classes and rates

The ErbStG divides beneficiaries into three tax classes. In broad terms, Class I covers the closest family (spouses, registered partners, children and certain other descendants), Class II covers more distant relatives such as siblings, nieces and nephews, and Class III covers everyone else, including unrelated beneficiaries. Each class carries its own personal allowance (Freibetrag) and its own progressive rate scale: closer relationships enjoy higher allowances and lower rates, while unrelated heirs face smaller allowances and higher rates.

Because the precise allowance and rate figures are fixed by the ErbStG and may be amended, heirs should confirm the current statutory amounts in the Act itself before relying on any number. Note also that, where only limited liability applies, personal allowances may be restricted or adjusted under the ErbStG, so non-resident heirs should check their precise entitlement.

Special reliefs: family home and business succession

Two reliefs are especially important in cross-border planning. First, there is a relief for the family home (Familienheim), which can exempt a residence inherited by a surviving spouse or children, subject to conditions, including, in some cases, continued use of the property as a home for a defined period. Second, the business succession relief (Unternehmensnachfolge) can substantially reduce or eliminate tax on qualifying business assets passed to heirs/legatees, in order to protect operating businesses and jobs.

Both reliefs come with conditions and, critically, with clawback risks: if the statutory holding or use requirements are not met, for example, if a business is sold or wound down, or a home ceases to be used as required within the relevant period, the relief can be retrospectively withdrawn and tax reassessed. Heirs/legatees who intend to rely on these reliefs must understand the ongoing conditions before, not after, taking any step that could breach them.

Treaty interaction: avoiding double taxation on cross-border estates

The defining difficulty for heirs/legatees facing German inheritance tax cross-border estates is the risk that two countries tax the same inheritance. A German-resident heir/legatee with foreign assets, or a foreign-resident heir/legatee with German property, can find that both jurisdictions assert a claim. Relief comes from two directions: bilateral tax treaties on inheritances, where they exist, and unilateral crediting mechanisms under domestic German law.

How treaties allocate taxing rights

Germany has concluded only a small number of inheritance and estate tax treaties. Where a treaty applies, it typically allocates taxing rights between the residence state and the state where assets are situated, and resolves conflicts between them. The general pattern follows the broader logic of international tax: the state of situs may tax immovable property and business establishments, while the residence state taxes more broadly but gives relief for tax paid at source. The Federal Ministry of Finance (Bundesministerium der Finanzen) maintains official guidance and a list of Germany’s tax treaties, and the precise allocation always depends on the specific treaty text.

Credit versus exemption methods

Two main mechanisms prevent double taxation. Under the credit method (also applicable, if no inheritance tax treaty applies), Germany taxes the worldwide acquisition but credits the foreign inheritance or estate tax paid on the same assets against the German tax, if some further conditions are met. Under the exemption method (which may apply in case of an applicable inheritance tax treaty only), certain foreign assets are excluded from the German base altogether. Where no treaty applies, German domestic law (ErbStG §21) still provides a unilateral credit for comparable foreign inheritance tax paid on foreign assets, within statutory limits. The result is that even an heir/legatee in a country without a German inheritance tax treaty is often able to reduce or avoid double taxation through a credit.

Practical steps to claim relief

To secure treaty or unilateral relief, heirs should:

• Identify which assets are taxed in which country and on what basis.
• Obtain official evidence of the foreign tax assessed and paid (assessments, receipts and translations).
• Determine whether a treaty applies and which method, credit or exemption, it prescribes.
• Claim the credit or exemption in the German assessment, supported by documentation.
• Take advice on timing, because a credit generally depends on the foreign tax actually being paid on the same assets, and statutory time limits may apply.

Reporting, procedures, timelines and penalties

Procedure is where cross-border heirs/legatees most often come unstuck. German inheritance tax is administered under the Abgabenordnung and the ErbStG, and the obligations begin sooner than many beneficiaries realise.

Notification and filing obligations

The first obligation is to notify the competent German tax office of the acquisition. This is a reporting duty that arises promptly within three months after the heir/legatee becomes aware of the inheritance; the tax office may then request a full inheritance tax return. Because the applicable timelines are set by statute and strictly enforced, heirs should verify the exact deadlines with the relevant administrative sources and, where there is any doubt, treat the matter as urgent rather than assume a generous grace period. The competent local German tax office is the correct administrative contact for forms and procedural questions, while the BZSt handles cross-border administrative matters.

Immediate checklist, documents to gather:

• The death certificate and, where available, the will or certificate of inheritance (Erbschein).
• A schedule of German-situs assets with supporting title and ownership documents.
• Valuation evidence as at the date of death.
• Details of the deceased’s and the heir’s/legatee’s residence status.
• Evidence of any foreign tax assessed on the same estate.

Penalties and interest

Failure to notify or file on time, or late payment of assessed tax, can expose heirs/legatees to interest and penalties under the AO. For non-resident heirs/legatees, the risk is compounded by the delay and complexity of cross-border administration, correspondence can be slow to reach beneficiaries abroad, yet deadlines continue to run. Prompt engagement is the most effective protection.

Instalments, liquidity and security

Where an estate is asset-rich but cash-poor, a common situation with inherited real estate or a business, heirs/legatees may need relief from immediate payment. German law allows, in defined circumstances, for deferral or payment by instalments, which can be particularly relevant for business succession and real estate. These arrangements are discretionary and typically require an application and, often, the provision of security. Heirs/legatees anticipating a liquidity squeeze should raise the issue with the tax office and their advisers early.

Practical planning and remedial steps after inheritance

Even after death, there is scope to improve the outcome for heirs/legatees facing German inheritance tax cross-border liability, provided action is taken before deadlines pass and before relief conditions are inadvertently breached.

When restructuring and succession measures matter

Where a business or substantial real estate portfolio is inherited, the structure in which assets are held and continued can affect both the availability of reliefs and the long-term tax position. Decisions taken in the immediate aftermath of a death, whether to continue, restructure or dispose of a business, frequently determine whether business succession relief is preserved or lost to clawback. Advance clearances and binding rulings from German tax authorities can, in appropriate cases, provide certainty on how a proposed step will be treated before it is implemented.

Steps to protect reliefs and mitigate double tax

The likely practical priorities for advisers acting for heirs/legatees are to lock in valuations with robust evidence, to confirm and protect the conditions attaching to any family-home or business relief, to coordinate the timing of foreign tax payments so that German credits can be claimed, and to make any available elections within the statutory windows. Early advice is decisive because many of these levers close once deadlines pass or once a disqualifying step has been taken.

Conclusion

For heirs/legatees facing German inheritance tax cross-border estates, the decisive early questions are always the same: is liability unlimited or limited (extende limited), which assets are caught, how are they valued, and does a treaty or credit prevent double taxation? Because German inheritance tax attaches on death and the reporting clock starts quickly, the difference between a well-managed succession and an expensive one usually comes down to speed, documentation and the correct identification of reliefs. Given the interaction of German statute, international treaties and strict procedural deadlines, heirs, legatees and executors with any German nexus should obtain specialist German tax counsel at the earliest opportunity to confirm their liability, protect available reliefs and meet their reporting obligations on time.
