As a finance expert, I often get questions about how dividends work in money market mutual funds (MMMFs). One area that confuses many investors is accrued dividends—the earnings that accumulate but haven’t yet been paid out. In this article, I’ll break down everything you need to know, from how they’re calculated to their tax implications.

What Are Accrued Dividends?
Accrued dividends represent the earnings a money market mutual fund investor has earned but not yet received. Unlike stocks, where dividends are declared and paid on specific dates, MMMFs accrue dividends daily and pay them monthly.
How Money Market Mutual Funds Work
Money market mutual funds invest in short-term, high-quality debt securities like Treasury bills, commercial paper, and certificates of deposit (CDs). They aim to maintain a stable net asset value (NAV) of $1 per share while generating income through interest.
Daily Dividend Accrual Mechanism
MMMFs calculate dividends daily based on the fund’s yield. The formula for daily accrued dividends per share is:
Daily\ Dividend = \frac{7-Day\ Yield}{365} \times Share\ BalanceFor example, if a fund has a 7-day yield of 2.5% and you hold 10,000 shares, your daily accrued dividend would be:
Daily\ Dividend = \frac{0.025}{365} \times 10,000 \approx \$0.6849These dividends compound over time and are typically paid out at the end of the month.
Comparing Accrued Dividends Across Fund Types
Not all money market funds accrue dividends the same way. Below is a comparison of three common types:
| Fund Type | Dividend Frequency | Accrual Method | Risk Level |
|---|---|---|---|
| Prime MMMF | Monthly | Daily accrual | Moderate |
| Government MMMF | Monthly | Daily accrual | Low |
| Treasury MMMF | Monthly | Daily accrual | Very Low |
Why Daily Accrual Matters
Daily accrual ensures that investors earn interest even if they sell their shares before the payout date. This differs from bonds, where you only receive interest on coupon payment dates.
Tax Treatment of Accrued Dividends
In the U.S., accrued dividends from MMMFs are generally taxed as ordinary income. However, the tax treatment varies:
- Taxable MMMFs: Dividends are subject to federal and state income taxes.
- Municipal MMMFs: Dividends may be exempt from federal taxes and, in some cases, state taxes.
- U.S. Treasury MMMFs: Dividends are exempt from state and local taxes but subject to federal tax.
Example: Tax Impact on a $50,000 Investment
Assume you invest $50,000 in a taxable MMMF yielding 2.5%. Your annual dividend income would be:
Annual\ Dividend = 50,000 \times 0.025 = \$1,250If you’re in the 24% federal tax bracket, your after-tax dividend would be:
After-Tax\ Dividend = 1,250 \times (1 - 0.24) = \$950When Are Accrued Dividends Paid?
Most MMMFs pay accrued dividends on the last business day of the month. However, some funds offer different payout schedules:
- Monthly (most common)
- Quarterly (rare for MMMFs)
- Reinvestment (dividends buy more shares)
Impact of Early Redemption
If you sell your shares before the payout date, you still receive accrued dividends up to the sale date. For example:
- Purchase Date: June 1
- Sale Date: June 15
- Payout Date: June 30
You’ll receive 15 days of accrued dividends at the time of sale.
Calculating Accrued Dividends: A Step-by-Step Example
Let’s say you invest $25,000 in a MMMF with a 2.0% 7-day yield. Here’s how to compute accrued dividends over 10 days:
- Daily Yield:
Daily Dividend:
25,000 \times 0.00005479 \approx \$1.369710-Day Accrual:
1.3697 \times 10 \approx \$13.70This amount will be paid out at the end of the month.
Key Considerations for Investors
- Reinvestment vs. Cash Payout
- Reinvesting dividends compounds returns.
- Cash payouts provide liquidity.
- Expense Ratios and Net Yield
High expense ratios reduce net yield. Always check the net 7-day yield after fees. - Regulatory Changes
Post-2008 reforms (SEC Rule 2a-7) tightened MMMF regulations, affecting dividend stability.
Final Thoughts
Accrued dividends in money market mutual funds ensure you earn interest daily, even if payouts happen monthly. Understanding how they work helps optimize returns and tax efficiency. Whether you’re parking cash short-term or seeking stable income, MMMFs remain a solid choice—just be mindful of fees and tax implications.
