Bond yield

This is the annual yield of your municipal bond or bond fund.

Estimated taxable income

This is your total income, after exemptions, adjustments, and deductions. We use this, along with your filing status, to determine your marginal income tax rate. You can use last year's tax return as a guide to what your taxable income will be for the current year. Your taxable income can be found on your income tax form 1040 or 1040A. Make sure to increase or decrease the amount to compensate for any changes to your current year's income.

Federal tax filing status
