Deductions & credits

Thanks for your answer!

  1. So on Form 4562, if I elect to take the car depreciation as a Section 179 deduction,  I see that I can no longer take the Special depreciation allowance (Line 25).  Instead, I would have to use the depreciation method on Lines 26 (e) - (h), and then take the amount on Line 26 (h) into Line 26 (i) as a Section 179.  Then, I'd report that number into Part I Line 7.  Am I doing this correctly?
  2. The instructions for Form 4562 says that I can take Part II Special Depreciation Allowance only if it's a "tangible property depreciated under MACRS with a recovery period of 20 years or less." I think the MACRS depreciation for a car is 5 years recovery period, right? So,if I were to take Section 179 deduction for the car, would the car still qualify for special depreciation? If yes, would special depreciation only be for tax year 2019?
  3. The car was used >50% in activities for the rental property (co-owned by people in a Partnership) . Would the section 179 (only applied to the business usage portion of the car) extend to the partnership or only my dad?
