Deductions & credits

Correct, I am starting the business May 2021, plan on purchasing a SUV (6000lbs+) in December 2021 and my question is for when I file taxes in 2022. I'm not sure if I will have any income from the business in 2021, that is expected in 2022. My income for 2021 is mainly through my personal job, which I want to deduct from.
