> Defer US taxes by reinvesting your taxable income into the economy as business expenses, depreciating assets, etc.

Be really careful when doing this. Make sure you have a great accountant - if you go more than a few years without turning a measurable profit, your risk of being audited apparently goes up. My accountant personally cautioned me about this since my business has been in an R&D phase for 5 years so we've been showing a small loss every year. The last thing you want is for the IRS to decide you've been cheating on your taxes.

This is true for most businesses (they will reclassify it as a "hobby" where expenses aren't deductible, though you can fight that in tax court or real court if you want to) - but for rental properties you can go for decades with no profits (because of depreciation).

Can you elaborate? As a business owner in the U.S. I can opt to reinvest all revenue back into the business, thus would show zero net profit but (presumably) increase my company’s value. (And remember there are other taxes and fees paid to various governments, not just tax on income/profit, so it’s not typically like nothing gets paid.)

The point is creating failed businesses is legal and tax deductible.
