US Estate-Tax Returns: IRS Statistics of Income Filing Trends by Year
PlainEstate renders the IRS Statistics of Income (SOI) historical series for federal estate-tax returns, counts of returns filed, taxable returns, and aggregate gross-estate dollar amounts, from the irs_soi_estate_stats table.
Research period:
Every figure on PlainEstate is rendered directly from IRS Statistics of Income and state statutory data, no number is typed in by an editor. This page draws directly on IRS Statistics of Income and state statutory data, no figure is typed in by an editor.

Research question
How has the volume of federal estate-tax returns filed and the aggregate dollar amount of reported gross estate evolved over the years tracked by IRS SOI, and what does that trajectory show about the changing population of estates large enough to file?
Methodology
This ranking is generated fresh from the current the IRS dataset every time the page loads, not a fixed figure typed in once and forgotten. When the IRS publishes an update, our next data refresh picks it up automatically.
Records with no data reported are left out rather than shown as a false zero, since the IRS occasionally withholds a figure for data-quality reasons.
Every number on this page traces back to a specific the IRS record, so you can verify it yourself against the original source. See the methodology page for the full data pipeline and how often we refresh.

Findings
Top entity in the ranking
The top-ranked record in this dataset is 2022, with a value of 6,158 on the Returns filed column. The full top-6 set is rendered in the table above. Every value derives from the underlying irs_soi_estate_stats table; no number is hardcoded into this page. When the source agency publishes a revision and our ETL pipeline reingests, the ranking and the prose around it update on the next page load.
Distribution shape
The gap between the top-ranked record (6,158) and the 6th-ranked record (12,411) characterizes how concentrated the top of the distribution is. Where the top value is many multiples of the median value of the visible set, the population is highly concentrated, a small number of entities accumulate the bulk of the measured quantity. Where the top and bottom of the visible set are close together, the distribution is relatively flat across the top end. The full distribution beyond this top-6 cut is summarized in the aggregate context section below and explored in the linked entity profiles.
Aggregate context
Across the full irs_soi_estate_stats population, the aggregate query returns the following summary statistics. These anchors situate the top-6 ranking against the underlying population: how many records exist in total, what the sum of the ranking column is across all qualifying rows, and what the mean per-record value looks like. The methodology page documents the exact filter applied by the aggregate query (records with null or zero values on the ranking column are excluded). The aggregate row is computed by the same database engine that renders the ranking above, against the same snapshot.
Source provenance
The records in this ranking originate from U.S. Internal Revenue Service Statistics of Income Division, specifically the IRS SOI Estate Tax Return Statistics. PlainEstate ingests each new release from the source agency and republishes the figures here automatically, so this page always reflects the current dataset rather than a fixed snapshot. The methodology page documents the source URL, the vintage date, and the transformation steps applied during ETL.
Why this ranking matters
Rankings like this one let a reader scan a population quickly and identify outliers, concentrations, and patterns that warrant deeper investigation. The detail pages linked from each entity in the table above give the full per-entity context: time-series history where available, related metrics from adjacent tables, and links onward to the underlying source records. The methodology page explains how an entity earns inclusion in the dataset and how the ranking column is computed at the source.
What this analysis cannot tell us
IRS Statistics of Income (SOI) estate-tax return data covers federal Form 706 filings only. Estates valued below the federal exemption for the year of death are not required to file Form 706, so the returns-filed count is a measure of estates large enough to trigger the federal filing requirement, not a measure of the total population of US decedents. The dramatic decline in filings since 2010 reflects the legislative increase in the federal exemption amount more than any underlying demographic shift in the size distribution of US estates. The 'taxable returns' subset is smaller than 'returns filed' because some filed returns claim deductions or marital-deduction transfers that reduce taxable estate to zero. Gross-estate dollar aggregates reflect the value of estate assets as reported on Form 706 at the date-of-death valuation (or alternate valuation date if elected), which is generally fair market value. Year-over-year changes in aggregate gross estate reflect a combination of underlying asset-value movements, changes in the size distribution of filing estates, and the shifting exemption threshold that determines which estates file at all. The IRS SOI series carries a multi-year publication lag, the most recent year shown is the most recent year for which SOI has completed its statistical processing of completed estate-tax returns.
