What Is ZTAX ETF? Returns, Expense Ratio, Holdings, and Alternative ETFs Explained
ZTAX ETF, the X-Square Municipal Income ETF, is an actively managed fund that selects municipal bonds from U.S. territories in pursuit of income exempt from federal income tax. Investors should weigh its semiannual distribution structure, the tax treatment of municipal bond distributions, interest rate and credit risk, and how its management differs from similar municipal bond ETFs.
What Is the X-Square Municipal Income ETF?
The ZTAX ETF is an actively managed ETF that invests in U.S. dollar denominated municipal bonds issued by Puerto Rico, Guam, and the U.S. Virgin Islands, with the goal of generating income exempt from federal income tax. It does not follow a specific index. Instead, it decides its holdings based on each issuer's fiscal condition and the characteristics of the bonds.
It suits investors who understand the tax characteristics of municipal bond income within the U.S. tax system and can accept the credit and interest rate risk of bonds from specific U.S. territories.
This ETF is managed by X-Square Capital using an active (actively managed) approach.

X-Square Municipal Income ETF Performance and Trends
Return trends can be affected by interest rate expectations, the credit conditions of issuers, and shifts in risk appetite in the municipal bond market. In particular, bonds with longer maturities can be more sensitive in price to interest rate changes, and the results of active selection decisions are also reflected in performance swings.
Fund flows in the municipal bond market can vary with demand from investors who prioritize tax efficiency, interest rate expectations, and the fiscal conditions of issuing regions. When trading, check the bid-ask spread and trading conditions, and also consider the possibility that the market price may differ from the net asset value.
X-Square Municipal Income ETF Strengths and Weaknesses

X-Square Municipal Income ETF Investor Checkpoints
When reviewing the ZTAX ETF, consider your tax residence and tax treatment, the fiscal condition of the municipal bond issuers, and sensitivity to interest rate changes. When trading, also check the bid-ask spread and the possibility that the market price may deviate from the net asset value.
| Checkpoint | What to Check | Current Status |
|---|---|---|
| Tax Treatment | Whether taxation applies by residence and account type | Individual review needed |
| Interest Rate Sensitivity | How interest rate changes may affect municipal bond values | May fluctuate |
| Credit Risk | Issuers' fiscal conditions and bond credit quality | Review needed |
| Trading Conditions | Bid-ask spread and possible gap between market price and net asset value | Check liquidity |
This product focuses on bonds issued by specific U.S. territories. As a result, changes in the fiscal, policy, and economic environment of those regions can act on the portfolio in a concentrated way. If rising interest rates, deteriorating credit quality, and weaker trading conditions coincide, the gap between market price and net asset value can also widen.
The ZTAX ETF is an active product for investors who want to access municipal bonds from U.S. territories with the goal of income exempt from federal income tax. Because its holding regions and management judgment differ from typical national municipal bond exposure, it is best reviewed after understanding the tax character of its distributions and the interest rate, credit, and liquidity risks.
