Setting up depreciation books for US Federal MACRS TAX rule in AX 2009

Hi All,

I am working on setting up depreciation books for US Federal Macrs TAX rule.

Example: Let’s say I have one FA item in USD 44,305, service life: 5 yrs, date placed in service: 2006/1/1; MACRS rule applied: 5yrs 200% Decline balance with Half-year convention. The followings are the results I got from CPA firm and AX:

2006 2007 2008 2009 2010 2011

CPA’s amount 8,861 14,178 8,507 5,104 5,104 2,552

AX’s amount 8,861 14,178 8,507 5,104 7,656

You can see that AX depreciate USD 44,305 in exact 5 yrs, but based on CPA firm’s system and MACRS rule, the correct way to calculate the depreciation for this item is to use 6 yrs.

Anybody could help me tell how i can set up properly to comply with MACRS rule?

Thanks a lot for your kind help.

Jim.
