MUB Dividend: Yield, Schedule, and What to Expect

Last updated August 2026

Short answer

MUB's approximate ~3.4% (30-day SEC yield, federally tax-exempt; tax-equivalent ~5.5%+ for top brackets) yield (as of mid-2026) makes it an income-oriented fund, about $343 a year on a $10,000 position before tax. It tracks ICE AMT-Free U.S. National Municipal Index and passes through the income its holdings generate, monthly, net of the 0.05% expense ratio. If income is your goal, MUB earns its place as a yield-paying core holding. If total return is the goal, the yield matters less than cost and what it holds. Yield is a recent snapshot, not a promise; verify the current figure with iShares.

How does the MUB dividend work?

MUB holds what is in ICE AMT-Free U.S. National Municipal Index, collects the income those holdings generate, and distributes it to shareholders monthly, net of its 0.05% fee. The yield you see is trailing distributions divided by price, so it drifts as both change: a falling price raises the quoted yield without a single extra dollar being paid out.

MUB holds thousands of investment-grade municipal bonds and tracks the ICE AMT-Free U.S. National Municipal Index at a 0.05% expense ratio. Because muni interest is generally exempt from federal income tax, MUB's stated yield near 3.4% translates to a much higher tax-equivalent yield for high earners. Its effective duration of about 6 years means it carries genuine interest-rate risk, similar to an intermediate taxable bond fund.

What MUB's dividend pays on a real position

  • Approximate yield: ~3.4% (30-day SEC yield, federally tax-exempt; tax-equivalent ~5.5%+ for top brackets) (mid-2026).
  • Income on $10,000: roughly $343 a year before tax, or about $3,430 on $100,000.
  • Versus the market: the S&P 500 yields around 1.2%, so MUB pays more.
  • Schedule: monthly, in line with how this kind of fund collects income. iShares publishes the exact ex-dividend and pay dates.
  • Fee: the 0.05% expense ratio comes out before you receive anything, so the yield above is already net of it.

How MUB distributions are taxed

MUB distributes interest rather than corporate dividends, and interest is generally taxed as ordinary income rather than at the lower qualified-dividend rates. US Treasury interest is usually exempt from state and local tax, and municipal interest is usually exempt from federal tax, which is why funds like this often sit in a tax-advantaged account. iShares's annual 1099 shows the actual split. Inside an IRA, Roth, or 401(k) none of it applies while the money stays in the account. Full detail is in how dividends are taxed. This is not tax advice.

The bottom line on the MUB dividend

The bottom line: at an approximate ~3.4% (30-day SEC yield, federally tax-exempt; tax-equivalent ~5.5%+ for top brackets) yield, MUB is an income-oriented fund. If income is your goal, its yield earns its place alongside the ICE AMT-Free U.S. National Municipal Index exposure it carries. If total return is the goal, the yield matters less than cost and what it holds. Treat the figure as a moving snapshot, not a fixed rate, and verify the current yield with iShares.

FAQ

What is MUB's dividend yield?

+

Approximately ~3.4% (30-day SEC yield, federally tax-exempt; tax-equivalent ~5.5%+ for top brackets) as of mid-2026. On a $10,000 position that is roughly $343 of distributions a year before tax. The S&P 500 yields around 1.2%, so MUB pays meaningfully more than the broad market. Yield is trailing distributions divided by price, so it moves when either changes; verify the current figure on iShares's fund page.

How often does MUB pay a dividend?

+

MUB is a bond or Treasury fund, and funds of that kind almost always distribute monthly rather than quarterly, because the income they collect arrives monthly too. iShares publishes the exact ex-dividend and pay dates in MUB's distribution calendar, which is the figure to rely on.

Does MUB pay monthly dividends?

+

Yes, MUB is the kind of fund that distributes monthly. That suits people who want the income to arrive on a regular cadence, though monthly payments make no difference to total return, only to timing. Confirm the schedule on iShares's distribution calendar.

Where does MUB's dividend come from?

+

MUB tracks ICE AMT-Free U.S. National Municipal Index and holds names such as MUNI, MUNI, MUNI, MUNI. The fund collects the income those holdings generate and passes it through to you. The 0.05% expense ratio is taken out along the way, so the yield you see is already net of the fee: you do not pay it separately.

When is MUB's ex-dividend date?

+

iShares sets and publishes it on MUB's fund page, and it moves with each distribution, so we do not quote a fixed date here. What it means is the cutoff: buy on or after the ex-dividend date and the seller keeps that distribution. Buying just before the ex-date to capture a payment is not free money, because the fund's price typically drops by roughly the distribution amount when it goes ex.

Can I reinvest MUB dividends?

+

Yes. Most brokers let you turn on automatic dividend reinvestment (a DRIP) so MUB distributions buy more shares, often fractional ones, without you doing anything. It compounds the position over time. It does not change the tax treatment: in a taxable account the distribution is taxable in the year it is paid, whether you reinvest it or take the cash.

Is MUB a good choice for dividend income?

+

Walnut is informational, not investment advice. MUB yields roughly ~3.4% (30-day SEC yield, federally tax-exempt; tax-equivalent ~5.5%+ for top brackets), which is moderate: real income, but below what dedicated income funds target. At that rate, $100,000 in MUB generates roughly $3,430 a year before tax. The trade-off to check is what you give up elsewhere: higher-yielding funds often tilt toward slower-growing sectors or use options strategies that cap upside. See the best dividend ETFs roundup to compare.

Are MUB dividends qualified?

+

Mostly no. MUB distributes interest income rather than corporate dividends, and interest is generally taxed as ordinary income, not at the lower qualified-dividend rates. US Treasury interest is usually exempt from state and local tax, and municipal bond interest is usually exempt from federal tax, which is why bond funds are often held in tax-advantaged accounts. Your 1099 from iShares breaks out the actual categories. This is not tax advice.
