here are several options for 2022 for depreciating the equipment
1) only MACRS depreciation *(elect out of bonus/special depreciation and don't take any 179). if this represents 40% or more of the equipment purchased during the year, the mid-quarter convention would apply - this would produce the least depreciation deduction
2) 179 depreciation - any amount up to 100% of the cost but the actual deduction is limited to net business income so some might not be deductible in 2022 but would carry over to be a 2023 deduction
3) special/ bonus deprecition. this is automatic for 100% of the cost unless you elect out. it's like section 179 but does not have a business income limitation
4) ADS depreciation which is straight line over the ADS life -the class is O -other and the life is 10 years depreciation type is NP.
