The document discusses using prescribed-rate loans between spouses to split income and reduce tax burden. It provides an example where a high-income spouse loans $400,000 to a low-income spouse at 1% interest. The low-income spouse earns $32,000 in investment income and pays $4,000 interest. This shifts $28,000 in taxable income to the lower bracket spouse, saving an estimated $7,000 in taxes. It urges taking action now to set up such a strategy while interest rates remain low.
