Beto O’Rourke’s Bad Idea to Punish Conservative Churches

(Bloomberg Opinion) -- Beto O’Rourke has a terrible idea. The Democratic presidential candidate and former Texas congressman wants the U.S. government to take away the tax-exempt status of religious organizations — including churches and mosques — that oppose same-sex marriage.

When asked about this last week, O’Rourke said: "There can be no reward, no benefit, no tax break for anyone or any institution or organization in America that denies the full human rights, and the full civil rights, of everyone in America.”

His proposal would be a blow to religious organizations and the American tradition of a healthy civil society, along with the separation of church and state. The magnitude of affected organizations would be large. To take an example close to my heart, there are over 17,000 Catholic parishes and 76 million self-identified Catholics in the U.S.

Let’s step back. Why are religious organizations allowed to receive tax-deductible contributions in the U.S.?

Taxpayers have been able to deduct contributions to churches and other nonprofit organizations from their taxable income for over a century. A few years after the U.S. created an income tax, the top rate was increased significantly in order to provide revenue for World War I. There was concern at the time that such a high rate would dry up the funds available to nonprofits. So those contributions were made exempt from taxation.

An example of how this works: If you’re in the 37% individual income tax bracket, and you make a $100 contribution to a church, that $100 of income is not taxed. Instead of owing the government $37, you owe nothing. So the actual cost of the donation to you is $63, not $100. (You can deduct up to half of your adjusted gross income, and the deduction is only available to households that itemize.)

Religious organizations that qualify for the exemption must be organized and operated exclusively for religious purposes. None of their earnings can be used for the private benefit of an individual or shareholder. And they have to avoid lobbying or intervening in political campaigns. Religious organizations have been given wide latitude to govern themselves.

Because the deduction reduces the cost of a taxpayer’s philanthropy, economists believe it increases the amount of charitable giving in the U.S. Forthcoming research by economists and charitable-giving experts Jonathan Meer and Benjamin Priday finds that a 10% increase in the "price of giving" reduces philanthropy by a little over 10%. (The price of giving changes when Congress changes marginal income tax rates.) For households in the top tax bracket, eliminating the deduction entirely for religious organizations that oppose same-sex marriage — as O’Rourke says he would attempt to do if elected president — would increase the taxpayers’ cost of giving to those groups by 59%. This would cause their charitable contributions to plummet.
