** Automatic AMT calc. if ADS life is not equal to 40 years

*** Automatic AMT calc. if using accelerated life


For personal property acquired after 12/31/98, AMT and the 150% election under MACRS are calculated over regular MACRS lives instead of Alternative Depreciation System lives.

For qualified section 168(k) property, the AMT treatment will calculate the same as the Tax treatment.
