How Austria's Proposed 2026 Inheritance Tax Affects Cross‑border Estates (austria–germany): What Families, Executors and Advisers Must Do Now

Last reviewed: 17 May 2026. This guide will be updated when bill text is tabled or committee votes are scheduled.

Executive Summary: What Families, Executors and Advisers Must Do Now

Austria has had no general inheritance tax since the Constitutional Court struck down the Erbschafts‑ und Schenkungssteuergesetz in 2008, and no replacement statute has been enacted since. Transfers of property still trigger the Real Estate Transfer Tax (Grunderwerbsteuer), and gifts above certain thresholds must be reported to the tax authorities. In 2026, however, Austria’s parliamentary debate over reintroducing a broad‑based inheritance tax Austria has moved from political rhetoric to concrete legislative proposals, creating an urgent planning window for every family, executor and adviser with assets that straddle the Austrian–German border.

The practical implications of a potential Austria inheritance tax reintroduction are significant, and the following five steps should be taken immediately:

1. Inventory all Austrian‑situs and German‑situs assets, real estate, bank accounts, securities, business interests and personal property.
2. Obtain current‑date valuations for Austrian real estate (the Grundstückswertverordnung method or market appraisal) and German assets.
3. Review existing wills and choice‑of‑law clauses under EU Succession Regulation (Brussels IV) to confirm which jurisdiction’s succession law governs.
4. Engage dual‑jurisdiction counsel, an Austrian notary or lawyer and a German tax adviser, before making any irreversible transfer.
5. Prepare documentation packs (titles, trust deeds, prior gift records, residency history) ready for rapid advice if a bill is tabled.

This guide is written for high‑net‑worth families, executors administering cross‑border estates, trustees, family‑office counsel and tax advisers who need to understand the current legal position, evaluate the 2026 proposals and take concrete planning steps while the legislative outcome remains uncertain.

Current Legal Position on Inheritance Tax Austria: What Is Taxed Now

Real Estate Transfer Tax (Grunderwerbsteuer), Rates and Practical Effect

Although Austria does not levy a standalone inheritance tax, every transfer of Austrian real estate, including transfers on death and by lifetime gift, triggers the Grunderwerbsteuer. For transfers within the family (defined broadly to include spouses, registered partners, lineal relatives and siblings), the tax is calculated on the assessed property value (Grundstückswert) using a tiered rate structure:

For non‑family transfers the flat rate is 3.5 % of the higher of the purchase price or assessed value. A separate land registration fee of 1.1 % of the property value also applies on recording the new ownership in the Austrian Land Register (Grundbuch).

Reporting Obligations for Gifts and Inheritances

Austrian tax law requires that certain gifts be reported to the tax office (Finanzamt) even though no gift tax is currently payable. Gifts between related persons exceeding €50,000 within one year, and gifts between unrelated persons exceeding €15,000 within five years, must be notified. Failure to report can attract penalties. These reporting obligations under the Schenkungsmeldegesetz 2008 give authorities a paper trail that could become the enforcement backbone if a new inheritance or gift tax is enacted.

The 2008 Abolition, Constitutional Court Decision

The Austrian Constitutional Court (Verfassungsgerichtshof) ruled in 2007 (published 2008) that the existing inheritance and gift tax was unconstitutional because its reliance on outdated property valuations produced arbitrary and unequal tax burdens. Rather than reform the valuation rules, the Austrian parliament allowed the tax to lapse on 1 August 2008 without replacement. This history is critical: a new tax must satisfy the Constitutional Court’s equal‑treatment standard, and any proposal that relies on inconsistent valuations risks the same fate.

What the 2026 Proposals Would Change: Inheritance Tax Austria Reintroduction

The current parliamentary session has seen several parties table or publicly endorse proposals to reintroduce some form of inheritance, estate or wealth tax. While no single bill has passed committee stage, the main design options under discussion share several common features: a tax base covering both immovable and movable assets above a defined allowance, progressive rates, and a residence‑plus‑situs nexus that would capture Austrian real estate regardless of the heir’s domicile.

Industry observers expect the following broad design parameters based on publicly reported positions:

• Exemption thresholds, Proposals range from €500,000 to €1 million per beneficiary, with some models applying a separate, lower threshold for non‑family heirs.
• Rate bands, Reported models suggest progressive rates from approximately 5 % to as high as 25–30 % on the largest estates, though final rates remain subject to coalition negotiation.
• Business‑asset relief, Most proposals include some form of deferral or reduced rate for active business assets to avoid forced liquidation of family enterprises.
• Anti‑avoidance look‑back, Early indications suggest a look‑back period (potentially three to five years) for lifetime gifts made before the effective date, which would pull recent gifts into the taxable estate.

Legislative Timeline: Probability and Timing

The likely practical effect is that families have a finite planning window, measured in months, not years, during which actions taken under the current no‑tax regime carry no inheritance tax cost. Once a bill passes with a retrospective look‑back clause, that window closes retroactively for recent gifts.

How Austrian Proposals Interact with German Inheritance Tax: Cross‑Border Inheritance Austria Germany

Germany levies one of Europe’s most comprehensive inheritance taxes, governed by the Erbschaftsteuer‑ und Schenkungsteuergesetz (ErbStG). Understanding how the German system already applies to Austria–Germany estates is essential, because the reintroduction of an Austrian tax would create a dual‑taxation exposure that currently does not exist for most families.

Key features of the German system relevant to cross‑border estates:

• Tax classes and allowances. German law groups heirs into three classes. Spouses receive a personal allowance of €500,000; children receive €400,000 each. More distant relatives and unrelated heirs receive substantially lower allowances (€20,000 for Class III).
• Progressive rates. After allowances, rates range from 7 % (Class I, lowest band) to 50 % (Class III, highest band).
• Unlimited tax liability. If either the decedent or the heir is tax‑resident in Germany (or was resident within the previous five years), Germany claims the right to tax the worldwide estate, including Austrian real estate.
• Limited tax liability. Even where neither party is German‑resident, German‑situs assets (primarily German real estate and certain German business interests) are taxable in Germany.

Comparison Table: Inheritance Tax Austria (Proposed) vs Germany (Current)

Example Scenario: Austria–Germany Cross‑Border Estate

Consider a German‑resident couple who own a Vienna apartment valued at €800,000 and German bank deposits of €600,000. Under current rules, the Vienna property transfer on the first death triggers only Austrian Grunderwerbsteuer (approximately €6,750 at family rates on the deceased’s half‑share), and the German bank deposits fall within the surviving spouse’s €500,000 allowance, producing modest or zero German inheritance tax.

If Austria reintroduces inheritance tax with a €500,000 per‑beneficiary allowance and a 10 % rate on the excess, the Vienna apartment transfer could generate an additional Austrian tax liability of approximately €30,000 on top of the existing transfer tax. Simultaneously, Germany would claim worldwide taxation on the full estate. The absence of an Austria–Germany inheritance tax treaty means relief depends on unilateral credit provisions under German law (§ 21 ErbStG), which may not fully offset the Austrian charge. The total effective tax burden for this family could rise from under €7,000 today to over €50,000, a more than sevenfold increase.

Immediate Inheritance Planning 2026 Austria: Compliance Checklist for Families and Executors

For Families and Asset Owners (Trustees and Beneficiaries)

• Evaluate lifetime gifting. Transfers made before a new tax takes effect, and outside any look‑back period, can reduce the future taxable estate. However, any gift above the Austrian reporting thresholds (€50,000 intra‑family / €15,000 non‑family) must be notified to the Finanzamt. Document the date, value, parties and purpose meticulously.
• Review ownership structures. Assets held through Austrian or German corporate vehicles (GmbH, KG, Stiftung) may be treated differently under a new tax. Assess whether restructuring now, while no tax applies, is prudent. Transfers between structures may themselves trigger Grunderwerbsteuer or German tax, so model costs before acting.
• Obtain independent valuations. Both Austrian and German systems require asset valuations, but they use different methodologies. Commission parallel valuations now so you have a defensible baseline if rules change.
• Clarify residency and domicile. Austrian proposals are expected to include residence‑based triggers. Gather residency documentation for all family members across both countries, including days‑of‑presence records, tax registrations and official residence notifications (Meldezettel in Austria, Meldebescheinigung in Germany).
• Consider Pflichtteil exposure. Under Austrian succession law, compulsory‑share (Pflichtteil) claims by disinherited family members are calculated on the full estate value. A new inheritance tax would not reduce the Pflichtteil Austria entitlement, but it would shrink the net distributable estate, making careful drafting essential.

For Testators and Will Drafters

• Coordinate cross‑border wills. Under the EU Succession Regulation (Brussels IV), a testator may elect the law of their nationality to govern succession. If you hold dual citizenship or have assets in both Austria and Germany, a single professio juris election combined with jurisdiction‑specific wills can prevent conflict. Register Austrian wills with the Austrian Central Register of Wills (Zentrales Testamentsregister) and German wills with the Zentrales Testamentsregister of the German Federal Chamber of Notaries.
• Insert modular tax clauses. Draft conditional clauses that adjust bequests if an inheritance tax is enacted, for example, directing the executor to satisfy tax liabilities from a designated fund before distributing residuary gifts.
• Review beneficiary designations. Austrian pension plans, insurance policies and German Riester/Rürup products may pass outside the will but still be subject to inheritance tax. Align all beneficiary designations with testamentary planning.

For Executors and Estate Administrators: Cross‑Border Probate Austria

• Open parallel proceedings where required. Austrian probate (Verlassenschaftsverfahren) is handled by a court‑appointed notary (Gerichtskommissär). German probate for local assets may require a separate certificate of inheritance (Erbschein). Coordinate timing so that neither proceeding is delayed by the other.
• Notify both tax authorities. Austrian transfer tax filings are due within defined deadlines after the court issues the Einantwortungsbeschluss (decree of succession). German inheritance tax returns are due within three months of becoming aware of the inheritance.
• Manage the valuation timeline. Austrian real estate valuations for Grunderwerbsteuer and potential inheritance tax may diverge from German Bedarfswert calculations. Secure both early to avoid filing delays and penalty interest.
• Preserve records for look‑back audits. If a new Austrian tax includes retrospective gift provisions, executors will need to evidence any lifetime transfers made by the deceased in the preceding three to five years.

For Tax Advisers and Family‑Office Counsel

• Model dual‑jurisdiction exposure. Build scenario analyses showing total tax cost under (a) current rules, (b) Austrian tax at the low end of proposed thresholds, and (c) Austrian tax at the high end. Incorporate German credits under § 21 ErbStG and assess whether full relief is achievable.
• Confirm treaty positions. There is currently no bilateral inheritance tax treaty between Austria and Germany. Unilateral credit provisions in German law offer partial relief; monitor whether treaty negotiations commence alongside the Austrian legislative process.
• Time gifts defensively. If clients wish to make lifetime transfers, document the independent commercial rationale for each gift. Ensure valuations are arm’s‑length and that the transfer is completed, legally and economically, before any announced effective date.
• Prepare defensive filings. Consider whether protective gift‑tax returns should be filed in Germany for transfers of Austrian assets, even where no tax is currently due, to start limitation periods running.

Suggested Action Sequencing

1. Weeks 1–2: Complete asset inventory across both jurisdictions; gather residency documentation.
2. Weeks 3–4: Engage Austrian and German counsel; commission property valuations.
3. Weeks 5–8: Model tax scenarios; review and update wills; assess lifetime‑gifting options.
4. Weeks 9–12: Execute any agreed transfers; file Austrian gift notifications; prepare German defensive returns.
5. Ongoing: Monitor legislative progress; update planning as committee reports and bill text emerge.

What to Avoid: Anti‑Avoidance and Enforcement Risks

The urgency of estate planning Austria in 2026 must not lead to reckless action. Both Austrian and German authorities have well‑established anti‑avoidance doctrines, and structures that lack commercial substance are likely to be challenged:

• Artificial transfers. Transferring assets to shell entities or nominees shortly before a tax takes effect will attract scrutiny. Austrian tax law contains a general anti‑abuse provision (Missbrauch, § 22 BAO) and any new statute is expected to include targeted anti‑avoidance rules.
• Undervaluation. Transferring property at below market value, whether by gift or intra‑family sale, may be recharacterised. Independent, documented valuations are essential.
• Trust misconceptions. Holding assets in a foreign trust or Austrian private foundation (Privatstiftung) does not automatically place them beyond the reach of inheritance tax. Austrian proposals are expected to include look‑through rules for foundations, and German law already applies Erbersatzsteuer (substitute inheritance tax) to certain trust structures.
• Cross‑border relocation. Changing tax residence to avoid an Austrian tax carries its own risks, including German extended‑liability rules (five‑year post‑departure rule under § 2(1) No. 1(b) ErbStG) and potential Austrian exit‑tax triggers on certain asset classes.

The central message for advisers: every step taken must have a genuine, documented purpose beyond tax minimisation.

Practical Templates and Letters: What to Prepare Now

Preparedness is the most effective form of protection during legislative uncertainty. The following template documents should be drafted and kept current so that families and executors can act within days if a bill passes:

• Executor immediate‑action memo. A one‑page checklist covering: notification of Austrian and German courts; engagement of Gerichtskommissär; asset‑freeze instructions for banks; valuation commissions; insurance policy claims; and filing deadlines for both jurisdictions.
• Owner lifetime‑gifting pack. Includes: gift deed template (Austrian notarial form); Austrian Schenkungsmeldegesetz notification form; German gift‑tax return (Schenkungsteuererklärung); valuation instruction letter to appraiser; and a residency‑evidence checklist.
• Cross‑border asset inventory template. A spreadsheet capturing: asset description, situs (Austria / Germany / other), registered owner, current valuation, valuation method, date of acquisition, any encumbrances, and the applicable tax regime for each asset.

Early indications suggest that families who have these documents ready can reduce the time from bill‑enactment to completed planning by several weeks, a critical advantage when look‑back periods may apply.

Next Steps: Where to Get Urgent Advice on Inheritance Tax Austria

Cross‑border succession law Austria Germany is a specialist discipline that requires dual‑jurisdiction expertise. Families and executors should not attempt to navigate the current uncertainty without coordinated legal and tax advice in both Vienna (or the relevant Austrian province) and Germany.

Before a first consultation, prepare the following:

• Complete asset inventory (use the template above).
• Copies of all existing wills, trust deeds, and foundation charters.
• Residency history for all relevant family members (past ten years).
• Records of any lifetime gifts or loans between family members in the past five years.
• Current property valuations or recent purchase contracts.

Having these documents ready allows advisers to model exposure scenarios accurately and recommend concrete steps in the first meeting. To find an estate or inheritance lawyer with the right jurisdictional expertise, use the Global Law Experts directory.
