How will non-US residents be taxed when they buy bond ETF in US markets?
Non-US residents who purchase bond ETFs in US markets may be subject to withholding tax on any dividends they receive. The US Internal Revenue Service (IRS) requires US financial institutions to withhold a percentage of any US-source income paid to non-residents, including dividend payments from bond ETFs. The exact withholding rate may depend on the tax treaty between the US and the non-resident's home country.

In addition to dividend withholding tax, non-US residents who sell bond ETFs in US markets may also be subject to US capital gains tax. The capital gains tax rate may depend on the length of time the ETF was held and the non-resident's tax status. Non-residents may need to file a US tax return to report and pay any capital gains tax owed.

It is important for non-US residents to consult with a tax professional to understand their specific tax obligations when investing in US bond ETFs.
