I have per item pricing setup for the 4562, but the bill shows a multiple of that amount. Why?
Per item pricing for the 4562 is designed so that each asset listed on the federal and state depreciation schedules (if there is one) is an "item" billed. This is true even if the same asset is listed on both the federal and the state depreciation schedules.
Count the number of assets on the federal schedule and count the number of assets on the state schedule, and add the two numbers. That is the total number of items billed. That total, times the per item price, should equal the amount of the bill for 4562 items.
Note: Another option is to bill by form. This would charge the taxpayer a flat fee for Form 4562, regardless of the number of assets.
