What Is Tax Alpha? Why Should You Care?

When taxes don’t matter, and that is rarely the case for most investors, pre-tax returns are sufficient in determining whether the investment did well or poorly relative to a benchmark. But for taxable accounts, pre-tax returns provide an incomplete picture, and relying on them can lead to poor investment decisions. In such cases, using after-tax returns, after-tax benchmark returns, and Tax Alpha in your decision process is more relevant, and could help you to increase your wealth on an after-tax basis.
