The tax bill changed twice before the estate's inventory was right

The situation

The first figure Herman heard was $19,400, the estate administration tax the previous lawyer had calculated based on an inventory that was, at that point, still incomplete. By the time our office had finished reviewing the file we inherited from that lawyer, the corrected figure was closer to $31,000, a difference large enough that Herman wanted to understand exactly where it had come from before he authorized paying it.

His mother Doris had spent most of her working life as a veterinarian, building a small practice from a single rented space into a clinic with a steady client base and, by the time she died, real value as a going concern. Her estate, once everything was properly accounted for, sat somewhere between $1,200,000 and $2,500,000, made up of the clinic itself, the building it operated from, an investment portfolio, and a house. Herman, her son, was named sole executor. His sister Ifrah, an optometrist with her own practice, was the estate's other beneficiary, entitled to an equal half.

Herman had retained a different lawyer initially, someone recommended by a family friend, who began preparing the probate application and the inventory of assets it required. That lawyer left private practice partway through the file, for reasons unrelated to the estate itself, and the matter came to our office to finish. What we inherited was a partially completed inventory, some assets valued, others still marked as estimates, and a preliminary tax calculation built on those incomplete numbers.

Herman's first instinct was to treat the transition as a formality, assuming the new lawyer would simply pick up where the last one left off and finish a mostly-done job. What the file actually needed turned out to be closer to a rebuild than a completion, and that difference is what changed the number he had been given.

He was also, by his own admission, in no hurry to reopen a subject he thought had been mostly settled. Doris's death had come after a difficult final year, and the estate work had already taken more emotional energy than he had expected. Learning that a lawyer transition meant redoing work rather than finishing it, and that the number he had budgeted around might not hold, arrived at a point when he had little patience left for surprises. That reaction mattered, because much of what came next depended on Herman trusting a set of figures larger than the ones he had first been given, from a lawyer he had not chosen and had not yet had reason to trust.

Why this was harder than it looked

An estate's inventory is not a formality attached to probate, it is the document the estate administration tax is calculated against, and getting it wrong in either direction carries real consequences. Undervaluing the estate understates the tax owed, which can expose the executor personally if the shortfall is later discovered, since an executor is generally responsible for ensuring the estate's filings are accurate, not merely for filing whatever number a previous advisor produced. Overvaluing it means paying more tax than the law actually requires, money that comes directly out of what the beneficiaries eventually receive.

The inventory we inherited had several problems, none of them dramatic on their own, but adding up to a meaningfully understated total. The clinic building had been valued using an outdated assessment rather than a current appraisal, missing several years of appreciation in a stable commercial market. The clinic practice itself, its client relationships, equipment, and ongoing revenue as a business separate from the building it operated in, had been left off the inventory entirely, apparently on the assumption that it had no value distinct from Doris personally, which is rarely true of an established practice with staff and a client base that continues without its founder.

Doris's investment portfolio had been valued as of an approximate date rather than her actual date of death, a detail that matters because estate administration tax is calculated on the estate's value at that specific date, not on a convenient approximation from weeks before or after it. In a portfolio that had moved meaningfully over that period, the difference was not trivial.

Correcting all of this raised the estate's total value, and with it, the tax owed, which was not welcome news to either sibling. It also opened a genuine disagreement between Herman and Ifrah once the clinic practice needed its own valuation. Herman, who had spent more time helping their mother with the business side of the clinic in her later years, believed the practice's value should account for the fact that much of its goodwill was tied to Doris personally and would not transfer easily to a new owner. Ifrah, who had less day-to-day familiarity with the clinic's operations, was inclined to trust a higher valuation reflecting the clinic's revenue history without that discount, since a higher value for the practice also meant a larger inheritance for both of them, once the tax on it was paid.

There was a further wrinkle in how the file had been left. The previous lawyer's notes referenced a conversation with an appraiser about the clinic building that had apparently never been followed up on, and a placeholder figure for the investment portfolio that had been pencilled in as a rough estimate rather than confirmed with the investment firm directly. Neither gap was flagged clearly enough in the file for a reviewer to catch at a glance, and if we had simply filed the inventory as we received it, both errors would have gone forward into a sworn court document neither Herman nor our office could have easily corrected afterward without raising uncomfortable questions about how the mistake had happened in the first place.

What we did

1. Requested the complete file from the previous lawyer, including working notes, appraiser correspondence, and internal file memos, not just the draft inventory itself, so we understood which figures had already been confirmed with third-party sources and which were placeholder estimates never meant to be final. The draft document alone did not make that distinction clear, and treating an unconfirmed number as settled would have carried real risk once the inventory was sworn as part of the probate application.
2. Commissioned a current appraisal of the clinic building from a commercial real estate valuator, replacing the outdated municipal assessment figure the previous file had relied on with a value based on comparable recent sales in the same commercial corridor. That single correction, reflecting several years of appreciation the old assessment had never captured, alone accounted for a meaningful share of the difference between the first tax estimate and the corrected one.
3. Arranged a business valuation of the clinic practice through a valuator experienced with professional practices, addressing directly the question of how much of the practice's value depended on Doris personally, her reputation and referral relationships, versus the business's transferable assets, staff, equipment, and existing client base. That distinction gave both siblings an independent, defensible figure to work from instead of two competing personal impressions of what the practice was worth.
4. Recalculated the investment portfolio's value as of the actual date of death, working directly with the investment firm's records to pull an accurate snapshot rather than relying on the approximate figure the inherited file had used. Estate administration tax is calculated on that specific date's value, not a convenient nearby one, and in a portfolio that had moved meaningfully over the relevant weeks, the earlier approximation had understated the estate on its own.
5. Prepared a full explanation of the corrected inventory for both Herman and Ifrah, walking through each change from the original figures, the building appraisal, the practice valuation, and the portfolio recalculation, line by line, so neither sibling was simply asked to trust a larger number without understanding where it came from. That mattered particularly because the change worked directly against their immediate financial interest as beneficiaries.
6. Facilitated a direct discussion between the siblings on the clinic practice's discounted value, using the independent business valuation as the shared reference point rather than letting the disagreement remain a matter of Herman's recollection of his mother's business set against Ifrah's assumption about what a thriving clinic should be worth on paper alone. Walking through the valuator's own reasoning, rather than either sibling's starting position, let both of them settle on a figure neither had proposed but both could accept as genuinely independent.
7. Filed the corrected inventory and paid the adjusted estate administration tax, ensuring the estate's sworn filings reflected the accurate figures before any distribution was made to either beneficiary. That step protected Herman from the personal exposure an inaccurate filing would have carried, since an executor who signs an estate information return remains responsible for its accuracy regardless of who prepared the earlier draft.

The outcome

The corrected inventory brought the estate's total value up by several hundred thousand dollars over the original incomplete figure, and the estate administration tax paid reflected that correction, ending at roughly $31,000 rather than the $19,400 first estimated. That additional tax came directly out of what Herman and Ifrah would otherwise have inherited, a real cost neither of them welcomed, but one that reflected the estate's actual value rather than an inaccurate shortcut.

The clinic practice valuation settled as a compromise rather than a clear win for either sibling's starting position. The independent valuator's figure landed between what Herman had expected, discounted heavily for Doris's personal involvement, and what Ifrah had hoped for, valued closer to the clinic's raw revenue history. Both accepted the independent number as fair, even though neither had argued for it directly.

The estate was distributed on the corrected figures, evenly between the two siblings as Doris's will directed, without either of them contesting the final inventory once it was explained. Herman filed the corrected paperwork confident it would hold up if ever reviewed, a confidence the original, unfinished inventory could not have supported had it simply been filed as inherited, and one that mattered to him specifically because it was his name, not the first lawyer's, on the sworn document.

Herman later said the hardest part had not been the extra tax, real as it was, but the process of learning, partway through settling his mother's affairs, that the file he thought was nearly finished was not close to done. He kept the appraisal and valuation reports with the rest of the estate's permanent records, along with a short written account of why the original figures had changed, in case either he or Ifrah ever needed to explain the correction to anyone reviewing the estate years from now.
