Wouldn't it be nice to have a source of nontaxable income? You may be more fortunate than you realize. Listed here are a number of income items that the IRS does not tax.

1. Tax-free interest. The federal government does not tax municipal bond interest. This includes bonds issued by a state or municipality. The tax-free benefit increases the higher your income, but caution must be taken to ensure the underlying municipality is not in dire financial condition.
2. Health insurance premiums. For now, most health insurance premiums are tax free. This could change in the future to help pay for health care reform, but for most this benefit can be paid in pre-tax dollars.
3. Income from Roth IRA and Roth 401(k) accounts. While the amounts contributed into these retirement savings accounts are taxed, any earnings made on the contributions are federal tax free as long as holding period and distribution rules are followed.
4. Health savings accounts (HSA). Contributions and earnings in health related savings accounts are tax free as long as the proceeds in the account are used to pay for qualified health care expenses.
