MMIT vs TAFM

MMITANYLI MacKay Muni Intermediate ETF

TAFMAAB Tax-Aware Intermediate Municipal ETF

In short

MMIT Active muni bond-picking in an ETF wrapper. MacKay Shields' municipal desk has run MMIT since 2017, sifting roughly 900 investment-grade, AMT-free bonds for income exempt from federal tax, and paying it out monthly.

TAFM Active muni management in an ETF wrapper: AB steers roughly 600 intermediate-term municipal bonds toward after-tax income instead of hugging a benchmark, and charges a shade under the typical muni fund.

Stated mandate

MMIT The Fund seeks current income exempt from federal income tax.

TAFM The actively managed ETF seeks enhanced income and attractive risk-adjusted after-tax returns. It invests in an intermediate-duration municipal bond portfolio.

Why people hold it

• MMIT Genuinely active, not an index in disguise: MacKay Shields' muni team picks bonds on credit and yield-curve analysis, targeting a 3 to 10 year duration band.nylim.comstockanalysis.com
• A billion-dollar-plus fund and one of the more actively traded in the intermediate muni group, with roughly 900 bonds spreading issuer risk.
• Trading since 2017, a long run for an active muni ETF, and one of the stronger implementations in its intermediate muni peer group.
• Does the one job it advertises: current income exempt from federal income tax, distributed monthly.

• TAFM Costs 0.28% a year, under the muni ETF median and cheaper than active benchmark-mates FTMU (0.30%) and FTCA (0.35%).
• Actively run rather than index-replicating: managers shop across roughly 600 municipal bonds aiming at enhanced income and after-tax risk-adjusted returns.alliancebernstein.com
• Income is paid monthly, not quarterly, which suits investors who want muni coupons on a regular cadence.
• Sits in the upper tier of a crowded municipal bond peer group, one of the stronger active implementations in the category.

Worth knowing

• MMIT 0.30%, net of a fee waiver off 0.46% gross, sits near the category median but above index rivals: TAXI 0.05%, ITM 0.18%, EVIM 0.11% net of a waiver through February 1, 2027.
• Active management cuts both ways: holdings and results can drift from a plain muni index in either direction.nylim.com
• Income is exempt from federal income tax, not state tax, and the bonds still reprice when rates move.nylim.com

• TAFM Index rivals VTEB and SCMB charge 0.03%, so you are paying multiples of plain muni beta for the manager's judgment.
• Intermediate duration means the portfolio moves with interest rates, so this is a rate-sensitive way to hold munis.alliancebernstein.com
• Launched in December 2023 with a mid-size asset base, so the track record is short and it trades less heavily than the category's giants.
