TAXM vs VTEB

TAXMCBondBloxx IR+M Tax-Aware ETF for Massachusetts Residents

VTEBAVanguard Tax-Exempt Bond ETF

In short

TAXM Single-state muni investing, ETF-style: IR+M actively picks short-duration municipal and taxable bonds screened for after-tax income for Massachusetts residents. Narrow by design, and young (launched 2025).

VTEB Vanguard's national muni index fund, running since 2015 at three basis points, a tenth of what the typical muni ETF charges. Its benchmark screens for investment-grade bonds whose income is exempt from federal tax and the AMT.

Stated mandate

TAXM The Fund seeks attractive after-tax income while preserving capital. It actively manages a diversified portfolio of U.S.-dollar municipal and taxable short-duration fixed-income securities selected for relatively attractive after-tax income for Massachusetts residents.

VTEB VTEB seeks to track an index measuring the investment-grade segment of the U.S. municipal bond market. It uses passive sampling to approximate the index and generally invests in federally tax-exempt municipal securities.

Why people hold it

• TAXM A rare state-level mandate in an ETF: the portfolio targets after-tax income specifically for Massachusetts residents, not the national muni average.
• Active, not index-bound. IR+M builds a diversified mix of muni and taxable short-duration bonds, with capital preservation named alongside income in the objective.
• Holdings line up closely with the stated mandate, one of the tighter mandate-to-portfolio matches among muni funds.
• Pays monthly, the usual cadence income-focused bond investors look for.

• VTEB Three basis points a year against a 0.30% muni-ETF median. On tax-exempt bonds, where coupons are modest, that fee gap is a real slice of the payout.
• The index holds only investment-grade munis whose interest is exempt from federal income tax and the alternative minimum tax, so the income carries no AMT surprise.vanguard.com
• A multi-billion-dollar fund and one of the most heavily traded in the muni category, which tends to show up as tight bid-ask spreads. Income is paid monthly.
• It has tracked its benchmark closely and sits among the strongest implementations in a crowded muni bond peer group.

Worth knowing

• TAXM At 0.35%, it costs more than its muni peer group's typical fee and far more than broad index munis like VTEB (0.03%) or MUB (0.05%).
• Small and thinly traded, so spreads can run wider than in mainstream muni ETFs.
• Launched in 2025, so the track record is short and the state-specific focus is narrower than a national muni portfolio.

• VTEB Federal exemption, not blanket coverage. Income can still be taxable in your home state, which is why single-state funds like NYF exist alongside it.vanguard.com
• Credit quality is investment grade, so rates are the main swing factor: when muni yields rise, bond prices and the fund's share price fall.vanguard.com
• Sampling, not full replication. The fund owns a representative slice of a very large index rather than every bond in it.vanguard.com
