Commercial buildings and improvements generally are depreciated over 39 years, which essentially means you can deduct a portion of the cost every year over the depreciation period. (Land isn’t depreciable.) But enhanced tax breaks that allow deductions to be taken more quickly are available for certain real estate investments:
1. 50% bonus depreciation. This additional first-year depreciation allowance is available for qualified improvement property. The break expired December 31, 2014, but has been extended through 2019. However, it will drop to 40% for 2018 and 30% for 2019. On the plus side, beginning in 2016, the qualified improvement property doesn’t have to be leased.
2. Section 179 expensing. This election to deduct under Sec. 179 (rather than depreciate over a number of years) qualified leasehold-improvement, restaurant and retail-improvement property expired December 31, 2014, but has been made permanent.
