What does this mean for investors?
These are both high-quality bond funds. Both delivered nearly identical returns over the past five years and don’t differ much in expense ratios or volatility.
However, these funds differ significantly in tax treatment. The VGIT’s U.S. Treasury focus means investors pay taxes on income in taxable accounts. But the main advantage for MUB is its focus on a broad basket of municipal bonds, which are generally excluded from federal income tax. This means investors in high tax brackets may prefer MUB over VGIT.
The main advantage of VGIT is that it is relatively safe from credit risk because the U.S. government fully backs Treasuries. Investors may prefer it if they are investing in a taxable account or are in a relatively lower tax bracket.
