CGSM vs TAXS

CGSMBCapital Group Short Duration Municipal Income ETF

TAXSANorthern Trust Short-Term Tax-Exempt Bond ETF

In short

CGSM Muni income on a short leash: about 600 municipal bonds kept at the short end for federally tax-exempt income, paid monthly, at 0.25% a year. Less rate whiplash than long-dated muni portfolios, and priced under the muni-fund middle.

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.

Stated mandate

CGSM The fund seeks current income exempt from regular federal income tax while maintaining a short-duration profile and preserving capital.

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.

Why people hold it

• CGSM Short duration is the point: bonds maturing sooner move less when rates do, so the ride tends to be milder than a long-dated muni portfolio's.
• 0.25% a year sits below the muni-ETF middle, and the income it targets is exempt from regular federal income tax.
• About 600 bonds, monthly distributions, and a multi-billion-dollar asset base that keeps the fund reasonably easy to get in and out of.
• One of the stronger showings in a crowded muni bond field, where most of the shelf is long-duration and index-tracking.

• 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

Worth knowing

• CGSM Plain index muni funds cost less: VTEB and SCMB charge 0.03% against 0.25% here. That gap is the price of a managed short-duration portfolio.
• Federal tax exemption is not blanket tax-free. State and local treatment depends on where you live and where the bonds were issued.
• It opened in 2023, so the record is short next to muni funds that have seen more rate cycles.

• 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
