Taxes, supposedly the main certainty in life, besides death. Are there ways to avoid it? Maybe, as this article suggests. Remember, I'm not a tax pro, nor do I play one a web series. Consultant a professional!
Remember, that while the tax my be deferred, such as an IRA, when you can withdraw it (without "penalty") you will still be paying taxes on that money, once it is available.
One option is a life insurance policy, where "...you borrow the money from yourself instead of the bank, then pay yourself the interest and repay the loan you took from your policy.” Obviously, with this method, you need to consult a professional!
Can it be used to invest, as an SDIRA or SoloK can? Again, for that, you need a tax expert to help you in that matter.
