If Excel doesn't have the right formula for you, make it! With Visual Basic for Applications (VBA), you can add formulas to Excel and use them in your spreadsheet. We'll be doing this shortly for something more particular to BASIS than taxes, but for now, the tax bracket calculation is a worthy exercise. You will receive a handout with instructions for a short activity that can be completed within the period.
Next up in the Taxes Project are discussions of the formulas used in the 1040EZ sheet and a peak into the Line5 sheet.
