Likely Benefits from HIFO Accounting

Abstract

New IRS rules on accounting for cost basis often impose on investors a decision regarding cost basis when selling shares. We investigate in a very practical way the likely benefits from choosing the highest-in, first-out (HIFO) method for tracking shares. Our results show that for realistic scenarios where investors plan for retirement, HIFO accounting can add about 2% to the investor’s total wealth at the retirement date. Above average tax rates and greater volatility increase the value of using HIFO accounting.
