Look, it’s pretty obvious that Uncle Sam wants people to build businesses and own real estate. 1% of the tax code tells us what we need to pay tax on-income. The other 99% of the tax code tells us how we can reduce our taxes. This is done by deductions, incentives, and depreciations. If I drive to my W2 job and work an overtime shift, I will pay the most in taxes that way. And to boot, the taxes are taken out before the money hits my pocket.
However, If I hop in my vehicle to go deliver a margarita machine from Life of the Party, then the mileage is tax deductible. The food I ate while I was making deliveries is tax deductible. My cell phone I used for GPS directions now becomes partially deductible. The home office that I work out of to book that job is a tax deduction.
So while each of those situations put money in my pocket, my business put the money in my pocket first and I pay the taxes on that money AFTER I take out my deductions.
