A tax on foreign remittances could hurt US.

Last month, the US House of Representatives narrowly passed a sweeping tax and spending bill that is the top legislative priority for President Donald Trump. Among its lesser-known provisions is a proposed 3.5 percent tax on remittances sent by anyone who is not a US citizen or national.
Currently, remittances are not taxed separately, as senders already pay income tax on the earnings they transfer to family and friends abroad. “The One, Big, Beautiful Bill” would upend that system—effectively taxing those transfers twice. But that’s not all. A tax on remittances—valued at $905 billion globally—would not only hit US households and low-income countries, where they can account for more than 30 percent of gross domestic product; it could also undermine key US national security and foreign policy priorities.
