What was California’s share of U.S. federal tax receipts as a percentage in 2022 using Treasury data?

1. What the question actually demands and where the official numbers live

The user asks for a single percentage: California’s portion of federal tax receipts in 2022 “using Treasury data,” which requires two confirmed figures from the Treasury (or linked authoritative datasets): a Treasury‑reported total federal tax receipts for the relevant fiscal or calendar year, and a Treasury‑attributable amount for California for the same accounting convention; the Treasury’s Fiscal Data “U.S. Government Revenue Collections” dataset and the IRS’s SOI gross collections by state (Data Book Table 5) are the primary sources to produce that number ^{[1] [2]}.

2. What the supplied sources actually contain and what they do not

The provided Fiscal Data landing pages describe the dataset and where daily and aggregate revenue collections are published, but the snippets do not include a confirmed numeric total for federal receipts in 2022 nor a Treasury‑published California share in a single cited line here ^{[1] [4] [5]}. The IRS SOI Data Book Table 5 is the canonical IRS table for “Gross Collections, by Type of Tax and State,” which is the likely place to extract a state‑level gross federal tax contribution, but the provided snippet does not include the 2022 numeric entries ^[2]. A third source, MoneyRates, reports that California paid $692 billion in federal taxes in 2022, but MoneyRates is an independent aggregator rather than the Treasury itself ^[3].

3. Why that gap matters to producing an authoritative percentage

A valid “Treasury data” percentage requires matching accounting conventions (fiscal vs. calendar year) and the official totals; using a state number from one source and a national total from a different accounting convention or non‑Treasury aggregator risks producing a misleading percentage. The Treasury/FiscalData site and FRED’s “Federal Receipts” series hold official totals and time‑series ^{[1] [6]}, and IRS Table 5 can provide state‑level gross collections, but none of the supplied snippets include both confirmed 2022 totals and the state breakdown simultaneously, so an exact percentage computed here would be insufficiently sourced ^{[2] [6]}.

4. What can be responsibly stated now, and the calculation path

It is responsibly reportable, per the supplied aggregator, that California’s federal tax payments in 2022 have been reported at $692 billion (MoneyRates) — a figure other outlets commonly cite when drawing state contributions to federal receipts ^[3]. To convert that into a Treasury‑based percentage, the correct next step is to retrieve the Treasury/FiscalData or OMB total federal receipts for 2022 (or the matching calendar/fiscal convention) and divide California’s gross collections for the same period by that total; both datasets are explicitly available via FiscalData and the IRS Data Book ^{[1] [2] [5]}.

5. Alternative viewpoints, potential biases, and recommended next steps

Sources that frame California as a “donor state” often pair state payment figures with federal outlays to the state to argue net contribution, a framing used by analysts with policy agendas on redistribution or tax fairness (see Rockefeller/CalBudget discussions for related analyses, though those cite differing conventions) ^[7]. Aggregators such as MoneyRates provide quick figures but should be cross‑checked against primary Treasury/Federal Reserve/IRS releases; the cleanest path to the authoritative percentage is to download Treasury/FiscalData totals for 2022 and IRS gross collections by state for 2022 (Table 5), confirm both use the same year definition, and then compute: (California gross collections ÷ U.S. total receipts) × 100 ^{[1] [2] [6]}.
