Bond taxation can vary widely. Treasury bond income is exempt from state taxes. Corporate bond interest, on the other hand, gets taxed at both the federal and state levels.
If you're looking to avoid federal taxes altogether while still keeping your interest rate sensitivity low, consider a short-term municipal bond ETF like the iShares Short-Term National Muni Bond ETF (SUB +0.01%)
This ETF tracks the ICE Short Maturity AMT-Free US National Municipal Index, which includes more than 2,500 issues.
These bonds are exempt from federal income tax and the alternative minimum tax (AMT), a parallel tax system designed to ensure that high-income earners pay a minimum tax even after deductions.
This iShares ETF is affordable, charging just a 0.07% expense ratio. As expected for a short-term bond ETF, its interest rate sensitivity is low, with an average duration of 1.84 years.
Though the fund's 2.45% 30-day SEC yield might not look impressive at first glance, it’s more useful to look at the tax-equivalent yield, which adjusts for the value of municipal bond tax exemptions. iShares currently estimates a 4.14% tax-equivalent yield for the fund.
Their methodology assumes the investor is in the top federal income tax rate, which is standard for national municipal bond ETFs. However, your personal yield will vary depending on your own tax situation and state of residence.
