Methodology

The Subsidy Ledger

Every dollar a tax-exempt hospital system takes from taxpayers, drug makers and patients, set against the free care a patient actually received.

Methodology version 1, November 2026. In use on health system profiles and state dossiers.

The rule

Charity care, Medicaid and Medicare shortfalls, bad debt and other community benefit claims are write-offs on the subsidy side, not offsets.

Hospital systems present community benefit as money given away. Each claimed shortfall is a line the hospital itself reports on Schedule H.

So the ledger counts those claims where they belong: as benefits the system writes off against the public. The only line kept apart is free care actually delivered to a patient, at cost.

That line is Schedule H Part I Line 7a, column (e): financial assistance at cost, net of any offsetting revenue. Where the system’s Medicare cost reports put the figure higher, the Worksheet S-10 cost of charity care appears in the note.

The Fair Share Test

Ratio = the filled ledger lines, added up, divided by free care actually delivered.

The result reads “$X in subsidies and write-offs for every $1 of free care a patient actually received.”

Only filled lines count. The ratio is marked “at least” with the number of lines filled, because every open line can only raise it.

The note gives a second ratio using the Worksheet S-10 cost of charity care from the Medicare cost reports.

The lines

Four groups, nineteen lines

Each profile carries the same ledger. A line stays a dash until its source file is read for that system. Nothing is prorated or imputed to fill a gap.

How each estimate is made

Every est. figure on the site

An estimate uses reported inputs and a stated rate. The source line on the page repeats the inputs and the arithmetic, so any reader can redo it.

Federal income tax exemption est.

Base times the 21 percent federal corporate rate.

On a health system profile, the base is the excess of revenues over expenses attributable to the system in its audited statements. One-time gains, such as a gain on early extinguishment of debt, are taken out.

On a state dossier, the base is net income from the CMS cost report, summed over the state’s hospitals with positive net income. Losses are not netted against profits.

State income tax exemption est.

The same base at the state’s corporate income tax rate for the tax year, cited to its source. Sales and use tax exemptions are not estimated.

On a system profile the headquarters state’s rate is applied to the whole base, without apportionment to other states. The line says so.

Property tax exemption est.

Land, land improvements and buildings at gross historical cost, from each hospital’s latest CMS cost report, times a commercial property tax rate.

The rate is from the Lincoln Institute of Land Policy and Minnesota Center for Fiscal Excellence 50-State Property Tax Comparison Study, stated by edition.

A system profile uses each state’s published rural commercial rate and shows a low and a high case; the ledger line carries the low case. A state dossier uses the state’s commercial effective rate, high case.

Estimated tax breaks on a state dossier est.
The federal income tax, state income tax and property tax (high case) lines above, added up for the state’s 340B hospitals. The total is shown against charity care at cost from the same cost reports.
Years of free care est.
Cash and investments from the audited balance sheet, divided by one year of free care at cost. Free care is Schedule H Line 7a, summed over the hospital filers. The result is rounded to the nearest year.
Margin on a state dossier est.
A system’s net income divided by its net patient revenue plus other income, from the cost reports of its hospitals in the state.

Methods still being set

Shown as a dash until decided
The 340B program spread Pending method
The gap between the discounted purchase price and the reimbursed price on drugs bought through the 340B program. The spread is pending a method decision.
Bond interest savings Pending method
Tax-exempt bond balances come from Form 990 Part X Line 20. The savings line needs a sourced spread between taxable and tax-exempt yields for the system’s own issues on MSRB EMMA.
Charitable deduction Pending method
Schedule B gives the contributions received. The deduction’s cost to the Treasury needs an assumed donor tax rate, which is not yet set.
Provider tax net gain Pending method
The federal match a state’s hospitals draw through a provider tax, less the tax they pay. It needs each state program’s report, starting with California’s Hospital Quality Assurance Fee.
