Pope Leo XIV, the newly elected pontiff, must answer to at least one more higher power: the IRS. The United States generally requires all citizens to file an annual tax return, even those who live out of the country. But assuming he doesn’t renounce his U.S. citizenship, Leo…has special tax considerations, both as a clergyman and now as the head of a foreign government. …many countries do not assess taxes on citizens living abroad. 

“Recent popes from Poland, Germany and Argentina were not taxed by their home countries,” said Jared Walczak, a vice president of the Tax Foundation… The pope’s job as a member of the clergy does not exempt him from U.S. taxes. American citizens abroad must generally file tax returns…according to the Internal Revenue Service. …

That means Leo will need to calculate the value of his earnings. The pope does not earn a set salary, but the Vatican covers his housing, food, travel and health care, and provides a monthly stipend for personal expenses. …Leo probably will need an accountant to determine how to translate such benefits into income for a U.S. tax return.
