SCMB vs TAXM

SCMBASchwab Municipal Bond ETF

TAXMCBondBloxx IR+M Tax-Aware ETF for Massachusetts Residents

In short

SCMB Schwab's take on the core muni sleeve: three basis points, thousands of AMT-free bonds from across the country, and a monthly distribution. Bottom-of-the-table pricing, no frills attached.

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).

Stated mandate

SCMB The fund seeks to track, before fees and expenses, the total return of an index representing the U.S. AMT-free municipal bond market.

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.

Why people hold it

• SCMB Three basis points a year, against a 0.30% median for muni bond funds. Among the top-graded names in the category, only Vanguard's VTEB matches that fee.
• Follows the ICE AMT-Free Core U.S. National Municipal Index across thousands of bonds and issuers, so no single borrower or state drives the portfolio.
• Plain passive plumbing done well: it stays close to its index, trades actively, and pays monthly. One of the stronger implementations in the muni aisle.

• 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.

Worth knowing

• SCMB Launched in 2022, so its live record is shorter than muni staples like MUB and VTEB, even though the strategy is the same broad-market idea.
• Bond math still applies. This is a portfolio of municipal bonds, so share prices move opposite to interest rates.
• National in scope, not single-state like NYF, so it is not built around any one state's tax rules.

• 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.
