4 Modified percentage. For each month during the tax year, figure the increase, if any, in the low-income portion of the building for that month over the low-income portion of the building at the close of the previous tax year (the amount on line 2 of the previous tax year's Form 8609-A). For example, if the previous tax year's low-income portion of .5000 remained at .5000 for the first 9 months of this tax year and then increased to .7500 for October, November, and December, then subtract .5000 from .7500 to get an increase of .2500 for each month. Add these amounts together, divide by 12, and enter the result. (This amount must be shown as a decimal carried out to at least four places (for example, .2500 + .2500 + .2500 = .7500, divided by 12 = .0625.)) 4
