TAXS vs TMNS

TAXSANorthern Trust Short-Term Tax-Exempt Bond ETF

TMNSBT. Rowe Price Short Municipal Income 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.

TMNS T. Rowe Price's short-maturity muni fund, launched in 2025 as part of a four-ETF push that filled out the firm's tax-free lineup. Active management, investment-grade bonds, and a fee well under the typical muni ETF.

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.

TMNS The fund seeks income and, secondarily, capital appreciation.

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

• TMNS Costs 0.18% a year, below the 0.30% median for muni bond ETFs, and cheap for a fund with a human picking the bonds.troweprice.com
• Actively run by James Lynch, who also manages T. Rowe's intermediate muni ETF, rather than tracking a fixed index.troweprice.com
• Holds short- and intermediate-term investment-grade munis, so it carries less interest-rate sensitivity than long-dated muni funds while seeking federally tax-exempt income.troweprice.com
• One rung of a four-fund muni ladder (short, intermediate, long, high yield), so the duration slot is yours to choose instead of blended for you.troweprice.com

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

• TMNS Launched in November 2025. The record is short, and any read on how it handles rate swings rests on limited history.
• Still a small fund that trades thinly, which can mean wider gaps between bid and ask prices.
• Index-tracking muni giants like VTEB, SCMB and MUB charge a few basis points. You are paying up here for active bond selection.
