Section 168 bonus depreciation on luxury autos

SUGGESTED

I know the final update reflecting 2015 tax law will not be released until version 2016.1 in early February 2016.  However, Bill and Lovisa have advised on this forum that updating depreciation methods in the TAX and AMT books to MA200 or MA150 will reflect 50% bonus depreciation.  For assets with code P, this is true.  However, for assets with code A, it isn't working.

Luxury autos are limited to regular depreciation of $3,160 in year one.  If bonus is elected, bonus is capped at $8,000, making the 168 Allowance $8,000 and regular depreciation $3,160 for a grand total expense of $11,160 for 2015.

I just updated a new luxury auto in our system and Sage is returning incorrect expense.  The system is showing $3,160 as the 168 Allowance and zero as the Current YTD and Current Accum.  The 168 Allowance should be $8,000 and the Current YTD should be $3,160.  Both the TAX and AMT books are wrong.

If not fixed by 1/8/16, our company will be forced to manually calculate depreciation on all luxury autos, manually update all of our reports and then delete and re-enter each 2015 auto in 2016 so we can force the accumulated depreciation amounts to be correct.  That's what we had to do last year.  When we purchased the software 18 months ago, we were told Sage could handle luxury auto depreciation for tax purposes.  It was wrong for 2014 and the 2015 update didn't fix it.

Almost every business needs the luxury auto depreciation limits to work.  When will this be fixed?
