In this guide, I break down everything you need to know about arbitrage mutual funds taxation in the US.

What Are Arbitrage Mutual Funds?
Arbitrage mutual funds exploit price differences between cash and derivatives markets. They buy stocks in the cash market and simultaneously sell futures contracts to lock in profits. These funds aim to deliver stable returns regardless of market direction, making them attractive to risk-averse investors.
Key Features:
- Low volatility – Returns are less dependent on market movements.
- Short-term focus – Trades typically last a few days to weeks.
- Tax efficiency – Gains are often taxed as short-term capital gains.
How Arbitrage Funds Are Taxed in the US
The tax treatment depends on the holding period and the nature of gains. Here’s a breakdown:
1. Short-Term vs. Long-Term Capital Gains
- If you hold units for less than a year, gains are taxed as short-term capital gains (STCG) at your ordinary income tax rate (10%–37%).
- If you hold for more than a year, gains qualify as long-term capital gains (LTCG), taxed at 0%, 15%, or 20% based on income.
Example Calculation:
Suppose you invest $10,000 in an arbitrage fund and sell after:
- 6 months for $11,000 → $1,000 gain (STCG, taxed at 24% bracket) = $240 tax.
- 18 months for $11,500 → $1,500 gain (LTCG, taxed at 15%) = $225 tax.
2. Dividend Taxation
Some arbitrage funds distribute dividends, which are taxed at:
- Ordinary income rates if held in a taxable account.
- Qualified dividend rates (0%, 15%, 20%) if held long-term.
3. Tax Efficiency Compared to Other Funds
Arbitrage funds are often more tax-efficient than equity funds but less so than index funds.
| Fund Type | STCG Tax Rate | LTCG Tax Rate | Dividend Tax Rate |
|---|---|---|---|
| Arbitrage Fund | 10%-37% | 0%-20% | Ordinary or Qualified |
| Equity Mutual Fund | 10%-37% | 0%-20% | Ordinary or Qualified |
| Index Fund (ETF) | 0%-20% (mostly LTCG) | 0%-20% | Qualified (usually) |
Strategies to Minimize Taxes on Arbitrage Funds
1. Hold for Over a Year
Since LTCG rates are lower, holding longer reduces tax liability.
2. Use Tax-Advantaged Accounts
- IRA or 401(k): Gains grow tax-deferred.
- Roth IRA: Tax-free withdrawals.
3. Tax-Loss Harvesting
Offset gains with losses from other investments.
Common Mistakes Investors Make
- Assuming Arbitrage Funds Are Always Tax-Efficient – They can generate short-term gains, leading to higher taxes.
- Ignoring State Taxes – Some states impose additional capital gains taxes.
- Not Tracking Holding Periods – Selling too early triggers STCG rates.
Final Thoughts
Arbitrage mutual funds offer stability but require careful tax planning. By understanding the holding periods and using tax-smart strategies, you can maximize after-tax returns. Always consult a tax advisor to align these funds with your financial goals.
