Are gains on bond ETFs held for more than one year taxed at a lower rate, similar to stocks and funds holding stocks? I'm referring to the change in price of the fund, not dividends.
Appreciation of a Capital Asset is a Capital Gain. In the United States, Capital Gains get favorable tax treatment after being held for 12 months.
From the IRS newsroom:
The IRS defines a Capital Asset as "most property you own" with a list of exclusions found in Schedule D Instructions. None of the exclusions listed relate to Bond ETFs.
