I just wanted to check I'm doing this right. A customer wants to do MACRS straight line depreciation, and I need to calculate each assets depreciation including forecast on the Half Year basis. 

Lets say we have "asset A" which is a 5 year property purchased 6 June 2010 for $12000 and the customers fiscal year end 30 September 2010.

1. Am I right in saying that half year applies to fiscal year not calendar year ?

2. You only take half the usual depreciation in the first and last years, so I just want to check I have the division right - since we calculate half - one - one - one - half (thats 5 years), should I actually divide the figures by 4 ?

30 Sep 2010 - 0.5 x 12000 / 4

30 Sep 2011 - 1.0 x 12000 / 4

30 Sep 2012 - 1.0 x 12000 / 4

30 Sep 2013 - 1.0 x 12000 / 4

30 Sep 2014 - 0.5 x 12000 / 4

thanks
