Section 179 deductions with a new business and purchasing in December

If I'm starting my business in May 2021 and I purchase an SUV in December 2021 - 

 

  • Can I still qualify for Section 179 deduction with bonus depreciation even though I haven't been in business all year?
  • If the SUV is purchased in December, and it's used 80% for business, can I still deduct 80% of the value even though it was only in service for a month (December) and I haven't been in business the full year? How does that work?
