Donald Trump said he would end US income taxes on Americans living in other countries, the latest in a string of tax proposals in the final stretch of the 2024 campaign.

His pledge could simplify the tax obligations for US citizens who live overseas. Americans, regardless of where they live in the world, have to file tax information with the Internal Revenue Service and some expatriates are required to pay US taxes, in addition to levies in the country where they reside.

“I support ENDING the Double Taxation of overseas Americans!,” Trump, the Republican presidential nominee, said in a statement addressed to voters living abroad. “Let’s put America First, together. Register to Vote, and vote Republican.”

The pledge, which would require congressional approval, would reduce paperwork and, potentially, the tax bills for the roughly 9 million Americans the State Department estimates are living overseas. The former president’s proposal was reported earlier by the Wall Street Journal.

The government requires expats to file US tax returns, but not all end up owing money to the IRS. The tax code offers credits to offset the cost of federal taxes owed.
