Taxation of nonprofit hospitals: a cost impact model

At a time when taxing authorities at all levels of government are reexamining present exemptions, nonprofit charitable hospitals may become concerned about potential new tax liabilities. The Tax Impact Model described here can predict the dollar amount of new taxes, the probable amount of shortfall in major payers' reimbursement for these expenses, and the resulting net financial impact. This model incorporates a set of issues that should be considered and factors for which data or assumptions are needed. It can be applied to hospitals singly or in groups. Here, the model's application to a single hospital shows that payer mix and pretax financial strength are important determinants of the impact of taxation. These findings also suggest that hospitals with a large disproportion of Medicare and Medicaid patients, and those with small revenue margins, are least able to absorb new tax expenses.
