Canada

I’m not sure how effective it is, but it seems like CRA has been tightening up on some kinds of business expenses, or at least my previous employer interpreted it that way. When people have things like company vehicles or phones, or get comparable benefits from work the value of those things being used for non-work related purposes is taxable. That’s also why there’s standards for things like mileage or per-diems so people can be compensated for realistic expenses, but not use it as a way to avoid income taxes.

We should also be careful about how we close some “loopholes”. Like it makes sense that a person can mortgage their personal property and use that to fund their business. It also makes sense that they can claim the interest on that mortgage as a tax deduction since it’s kind of a business related expense. It feels different when someone with a net worth less than a million does that compared to someone worth more than a billion, so I don’t think it’s closing the loophole altogether but putting limits like only claiming interest on something like $300k of debt (or something close to the average amount owed on a home of an average valuation).

I’ll also add that the idea behind reduced taxation on capital gains is it encourages people to invest in businesses and grow the economy. That makes sense economically. Canada also does better than some places(USA) in this way because capital gains are considered realized and paid on death so there’s not really a way to avoid them altogether, at best you’re putting it off for 60ish years. We also have things like the TFSA, which allows us to invest without being subject to capital gains tax. A person able to max out their RRSP/TFSA/CPP contributions would have a very comfortable retirement, while people earning significantly more have more limited options in deferring/eliminating their tax burden.
