That is what I find confusing about this. "A taxpayer my elect to capitalize and depreciate as an improvement, repair and maintenance costs as long as the taxpayer incurs the amounts as capital expenditures for financial accounting purposes. This election applies to all amount paid for repair and maintenance  treated as capital expenditures on a taxpayer's books or records for the taxable year." 

Since these expenses were so large I thought taking the election would be better than expensing. If I add as an improvement to depreciation schedule I can use Bonus Depreciation to write them off completely. I assume this treatment allows me to add them to basis but have not read that explicitly.

Thoughts?
