Not to defend these loopholes, but if you allow me to proselytize a bit... Why bother with those fancy tricks with your modest income when you can get tax-free gains anyway? OK, I exaggerate a little, but you can probably open a tax-free savings/investment account (Roth IRA (US), TFSA (CA), NISA (UK)). These usually have enough contribution room to meet your savings goals (you'll probably exceed them, but you can put those savings somewhere else, like a pension account or tax-deferred account). You can put a low-cost (< 1% of assets, per year) fund in them that owns every publicly traded company in your country/planet[0]. Now you're investing rather than getting around taxes, but your interest, dividends, and capital gains are now tax free. 0 - Vanguard's total-market ETFs, for example
