No one likes to pay taxes, but it’s a necessary part of living in a country which provides its citizens with a multitude of benefits. But just because you pay taxes doesn’t mean you can’t take advantage of available legal ways to keep your taxes low. Investors can enjoy tax-free income funds to grow wealth and minimize taxes.

What Is a Tax-Free Income Fund?

Let’s break the definition down into two parts; tax-free and income. An income fund is a mutual fund or exchange-traded fund (ETF) which pays dividends to shareholders. Investors use this type of investment to create an income stream from their investments. A tax-free fund is an investment with dividends that aren’t taxed. These types of tax-free income funds are usually called municipal bond funds.

If you’re in a higher tax bracket, a tax-free income fund which contains tax-free municipal bonds from your state can be a wise investment choice. But before getting swept away with the idea of investing in a tax-free income fund, consider your own tax bracket.

Tax Equivalent Yield

You need to determine whether you’ll benefit from investing in a tax-free income fund. Start out by considering your marginal tax rate. Next, compare the rate of return on comparable tax-free and taxable income funds. Finally, calculate which investment is likely to give you a higher after-tax return.

For example, Simon lives in California and is in the 25% federal marginal tax bracket. His state tax bracket is 4.5%. His total state plus federal tax rate is 29.50%. He has access to The Franklin California Tax-Free Income Fund Class A (FKTFX) and can buy it with no transaction fee through his Fidelity Investments brokerage account. The 30-day yield, or rate of return, is 2.39%. Simon knows he can get a tax free return for approximately 2.39%. 

Simon can get a taxable Securities and Exchange Commission (SEC) yield, or rate of return, of 4.88% if he invests in Vanguard Long-Term Corporate Bond Index Fund Admiral Shares (VLTCX). But which investment offers the best after-tax return? Given Simon’s 29.50% tax bracket let’s see if he’s better off investing in the 2.39% tax-free income fund or the 4.88% taxable income fund. Be aware that neither of the funds’ returns is guaranteed and they’re likely to fluctuate.

Simon’s 2.39% tax-free return is equivalent to a taxable yield of 3.337%. Any taxable return above 3.337% is preferable to the tax-free 2.39% return. Since he can earn a taxable return of 4.88% he’ll be better off in the taxable fund. You can compare tax-free with taxable yields on this tax-equivalent yield calculator.

Choose a fund issued with bonds from your state to compound your tax savings. Just remember that yields are subject to change and aren’t guaranteed.

The Bottom Line

If you’re looking for holdings for the fixed-income portion of your investment portfolio, these tax-free income funds may fit the bill. Just make sure to buy the municipal bond funds in accounts outside of your 401(k) plan, 403(b) or individual retirement account (IRA) to reap the best benefit of the tax-free yield.
