German Inheritance Calculator

Why a German Inheritance Calculator Matters When You Inherit Assets in Germany from the United States

A U.S. resident who learns of a German inheritance is not dealing with one legal system but two and the one most likely to determine their outcome, the German side, operates on deadlines and doctrines that have no equivalent in U.S. probate. The numbers behind that situation are rarely visible at the moment they matter most. A German inheritance calculator exists for exactly that reason: to surface, in ten minutes, the figures that drive the most consequential early decisions.

The Problem This Calculator Solves

Most U.S.-based heirs do not discover they have inherited from Germany through a formal notification. They learn through a cousin, a letter from a German bank, or a notice from a Standesamt that arrives months after the death. By the time they start understanding what they are dealing with, statutory clocks are already running, clocks they did not know existed.

Under § 1944 Abs. 3 of the German Bürgerliches Gesetzbuch, a U.S.-based heir has six months from the date they learn of both the death and their status as heir to formally disclaim the inheritance. After that date, acceptance is presumed by law. Under § 30 of the Erbschaftsteuergesetz, they have three months to notify the competent Finanzamt, a deadline that runs whether or not any tax is ultimately owed. Under § 1967 BGB, once acceptance attaches, so does personal liability for every debt the estate carries, including debts the heir never knew about.

The practical consequence: by the time an heir understands enough to ask the right questions, they may already have lost options that were available to them on Day 1. A calculator that shows them, in real time, how many days remain on each deadline and what the net estate looks like after German inheritance tax gives them back the capacity to decide — rather than drift toward a default acceptance by inaction.

What a Purpose-Built Calculator Does That a Generic One Cannot

Most inheritance calculators on the internet answer a narrow question: given an estate value and a relationship to the decedent, what is the German Erbschaftsteuer? That is a useful but incomplete picture. A U.S.-based heir to a German estate is not asking “what will I owe?” as their first question. Their first question is “should I accept this inheritance at all?” and that question depends on more than the tax.

The Estate Calculator Suite at our firm’s dedicated calculator site answers five connected questions in the order an actual heir needs them:

  • Step 1 — Deadlines. Enter the date you learned of the inheritance and your residence. The calculator tells you exactly how many days remain on the § 1944 Abs. 3 disclaimer clock and the § 30 ErbStG notification deadline, with color-coded urgency indicators.
  • Step 2 — Net estate value. Itemize the German assets (real estate, bank accounts, securities, business interests) and the known liabilities (mortgages, guarantees, tax debts). Because heirs inherit both under § 1922 BGB, net value is the real input to the accept-or-disclaim decision — not gross assets.
  • Step 3 — German inheritance tax estimate. Select your relationship to the decedent; the calculator auto-selects the correct tax class under § 15 ErbStG and the applicable allowance under § 16. Toggles apply the Familienheim exemption (§ 13 Abs. 1 Nr. 4), business-succession relief (§§ 13a/13b), and ten-year gift aggregation (§ 14). The progressive rates in § 19 compute on the excess.
  • Step 4 — U.S. reporting triggers. German tax is one question; Form 3520, FBAR, and FATCA are another. Even where no U.S. tax is owed, specific reporting may be mandatory and the penalties for missed filings can exceed the entire inheritance.
  • Step 5 — Preliminary indicator. A live summary pulls Steps 1–4 together, surfaces the days remaining, and gives a directional read on whether acceptance or disclaimer is the stronger choice given the numbers provided.

Why This Matters in Practice

We see three patterns regularly in our cross-border practice. Each could have been averted by earlier access to the kind of information this calculator surfaces.

The disclaimer window that closed four weeks ago. A daughter in Ohio learns through a cousin that her father died in Stuttgart four months earlier. She spends six weeks gathering documents, trying to read bank letters in German, and searching for counsel. By the time she reaches an attorney, twelve days remain on her clock. The estate includes an apartment worth €180,000 and a six-figure personal guarantee the father had given for a friend’s failing restaurant. The guarantee was called shortly after the death. With twelve days and incomplete information, her options are narrow and expensive. Had she started with a tool that showed her the six-month deadline the day she learned of the death, she would have had four additional months to evaluate — and the option to disclaim cleanly if the liabilities warranted it.

The estate accepted before anyone read the loan file. Three siblings inherit their mother’s Munich apartment. They do not disclaim. They engage a German notary to process the transfer. Only after the Erbschein issues do they discover a Grundschuld securing a €340,000 line of credit against an apartment worth €380,000. After sale costs, their practical recovery is near zero — on an asset they spent 14 months administering. A net-estate calculation at Day 1, even on rough figures with the “I am not confident I have identified all liabilities” flag checked, would have signaled that further discovery was warranted before the § 1944 window closed.

The tax notification that was never sent. A son in New York handles his mother’s estate administration competently — Erbschein obtained, bank funds released, apartment sold. He files his U.S. Form 3520 on time. He does not notify the German Finanzamt under § 30 ErbStG, because no one told him to, and the German tax liability is minimal after allowances. Eighteen months later, a Kontenabrufverfahren inquiry during an unrelated matter surfaces the unnotified inheritance. Penalties and interest have been accruing. What should have been a routine matter becomes a noncompliance proceeding that takes another ten months to resolve.

In each case, the calculator’s value is not that it would have told the heir what to do that requires case-specific legal advice. Its value is that it would have told the heir what they were looking at, in time to ask for that advice.

What the Calculator Cannot Do

A calculator cannot read a Grundbuch extract. It cannot surface a Grundschuld the heirs do not know about. It cannot evaluate whether a particular U.S. will is formally valid under EU Succession Regulation 650/2012, whether the estate qualifies for the § 13a/b Behaltensfrist, or whether treaty relief under the 1982 U.S.-Germany Estate and Gift Tax Treaty applies to specific assets. It cannot draft a Vollmacht that will actually be honored by a German bank. It cannot appear at the Nachlassgericht.

What the calculator does is triage. It tells you whether your situation is simple enough to handle without counsel, complex enough that professional input will pay for itself many times over, or already inside a narrow window where acting without counsel is high-risk. For the third category and we see it regularly — the calculator’s highest-value output is the days-remaining number on Step 1 and the “you should talk to someone this week” signal that follows.

How to Use the Calculator

The calculator is free, requires no registration, and runs entirely in your browser. Your data is not stored server-side unless you request a PDF copy of your results. Work through the five steps in order:

  1. Enter the date you learned of the inheritance. This is the legally operative date under § 1944 BGB, not the date of death, the date of notification, or the date the bank wrote to you.
  2. Itemize the assets and liabilities as best you know them. Exact figures are not required; order of magnitude is enough to drive a useful preliminary view.
  3. Select your relationship to the decedent. The tax class and allowance populate automatically.
  4. Complete the U.S. reporting section honestly; over-reporting is rarely the problem heirs face.
  5. Review Step 5. Print the PDF. Bring it to the consultation.

When the Calculator Signals That Counsel Is Warranted

If Step 1 shows fewer than 60 days remaining on your disclaimer window, or if Step 5 returns a close-call or disclaimer-warranted indicator, or if you checked the “uncertainty about undiscovered liabilities” box in Step 2 — the calculator has done what it was designed to do. It has surfaced a decision that depends on facts it cannot see, in a timeframe that makes delay expensive.

Our Initial Consultation is structured for exactly this point: a sixty-minute case assessment with a dual-licensed German and U.S. attorney, at a fixed fee of €394, conducted in English or German by video or phone. We review your calculator outputs against the facts of your specific matter, identify what the calculator cannot see, and outline the sequence of actions your situation requires.
