TAXS vs TAXX

TAXSANorthern Trust Short-Term Tax-Exempt Bond ETF

TAXXCBondBloxx IR+M Tax-Aware Short Duration ETF

In short

TAXS Northern Trust's muni index fund keeps every bond under five years to maturity and charges 0.05%, a fraction of the typical muni ETF fee. Roughly 1,700 federally tax-exempt bonds, none of them AMT bonds, with interest paid monthly.

TAXX Most muni ETFs can only buy munis. TAXX is run actively to chase the best after-tax income across two markets, keeping at least half in federally tax-exempt bonds and the rest in short-duration taxable debt.

Stated mandate

TAXS The fund seeks to track, before fees and expenses, the price and yield performance of the ICE Short-term Focused Municipal Bond Index. It is designed for tax-exempt income through passively managed, investment-grade municipal bonds with short-term maturities.

TAXX The Fund seeks attractive after-tax income while preserving capital. It is actively managed and invests in diversified municipal and taxable short-duration fixed-income securities, normally allocating at least 50% of assets to federally tax-exempt municipal securities.

Why people hold it

• TAXS 0.05% a year sits at the low end of the muni aisle, where the typical fund charges several times that, and matches the fee on MUB, the category's iShares heavyweight.
• Index rules admit only investment-grade bonds with under five years left to final maturity, so the portfolio skips the long-end price swings that define all-maturity muni funds.flexshares.com
• About 1,700 bonds, all exempt from federal tax and screened to exclude alternative minimum tax paper, with income distributed monthly rather than accrued.flexshares.com
• Passive, sampled, and run by Northern Trust's municipal desk, which has managed muni portfolios for more than 30 years. The index does the picking, not a manager's hunch.flexshares.comnortherntrust.com

• TAXX Hunts income in two markets: at least 50% federally tax-exempt munis, the rest short-duration taxable bonds, with a manager choosing whichever pays more after tax.
• Short duration by design, with capital preservation written into the stated objective, so less rate whiplash than long-dated muni portfolios carry.
• No index to hug. The mix can shift as the tax math between munis and taxable bonds changes, rather than sitting where a benchmark says to sit.

Worth knowing

• TAXS It launched in 2025 and trades lightly next to muni mainstays like VTEB and MUB, so spreads can run wider and the track record is short.
• Federally tax-exempt is not tax-free. That interest can still be taxed by your state and city.flexshares.com
• Sub-five-year munis generally carry lower yields than longer maturity portfolios. That is the other side of the milder rate sensitivity.flexshares.com

• TAXX At 0.35% a year, it costs more than plain-vanilla muni index trackers like VTEB and SCMB at 0.03%, and fees bite harder in short-duration bonds.
• Launched in 2024, so its track record is short and hasn't been tested across a full rate cycle.
• Payouts come on an irregular schedule rather than the fixed monthly rhythm many muni funds keep, so income timing takes planning.
