Some folks know about tax-loss harvesting; we wrote about it in newsletter #4. Tax-gain harvesting can also be advantageous in circumstances where your marginal capital gains rate is low. This might happen if you have carried over losses or when your income is low in a year due to time not working. You can sell an asset that has increased in value to enable the gain to be recognized and then immediately buy the asset back, creating a new, higher-cost basis. Unlike tax-loss harvesting, there are no wash sale rules to worry about.
