Here's my opinion, as someone who has zero education in economics. Feel free to voice your disagreement if you know better

If your personal expenses match your income but those expenses can't be written off, the resulting taxes result in a net loss for that month. This would be the same with a business if expenses could not be written off

And in my opinion, buying a house should not be written off as a personal expense, and neither should a business buying a warehouse be able to write it off either. If something can be sold, only the permanent loss should be considered an expense -- the remainder should be an asset

But bills and rent are generally permanent expenses. You don't get anything back after paying them, except the continuation of your services. I think these should be deductible. Similarly, if a business has to pay for a SaaS solution, I'm okay with that being a deductible

Is my thinking flawed?
