Where can I find specific formulas to figure double-taxed income and tax paid to other states?
When you figure credit for tax paid to other states, you must consider that the base income and tax from the other states returns may not be calculated in the same manner as the base income and tax on your Illinois return. For a list of formulas that identify the tax forms, line numbers, additions, and subtractions that you must use to compute the amount of double-taxed income and tax for Schedule CR, please refer to Publication 111, Illinois Schedule CR Comparison Formulas for Individuals. To obtain Publication 111, visit our web site at www.ILtax.com or call our 24-hour Forms Order line at 1 800 356-6302.
