Assets are located to save you on taxes.

• 1. Choosing which assets go where - Our Tax Coordination feature helps shield high-growth assets in the most tax-efficient account types. Choosing which assets go where From a tax perspective, you have three main account types at your disposal when saving for retirement:
  • Tax-deferred (traditional IRAs, 401(k)s, etc.), where taxes are paid later.
  • Tax-exempt (Roth IRAs, 401(k)s, etc.), where taxes are paid now.
  • Taxable, where taxes are paid both now and later.
  Because of their different tax treatments, certain types of investments are a better fit for certain accounts. Interest from bonds, for example, is typically taxed at a higher rate than stocks, so it often makes sense to keep them away from taxable accounts.
  This sorting of asset types based on tax treatments, rather than divvying them up equally across accounts, is known as asset location. And our fully-automated, mathematically-rigorous spin on it is called Tax Coordination.
  When Tax Coordination is turned on, the net effect is more of your portfolio's growth is shielded in a Roth account, the pot of money you crucially don't pay taxes on when withdrawing funds.
• 2.Rebalancing wisely – We take advantage of any existing cash flows to help minimize capital gains taxes while rebalancing your portfolio. When the weights of asset classes in your portfolio drift too far from their targets, our technology automatically brings them back into balance. But there's more than one way to accomplish this portfolio rebalancing. You can simply sell some of the assets that are overweight, and buy the ones that are underweight (aka "sell/buy" rebalancing), but that can realize capital gains and result in more taxes owed.
  So we first take advantage of any available cash flows coming into or out of your portfolio. When you make a withdrawal, for example, we intentionally liquidate overweight assets while striving to minimize your tax hit as much as possible (more on that below).
  And when you deposit money or receive dividends, we use those funds to beef up underweight assets
• 3.Choosing which taxable shares to sell (or donate)– Our TaxMin technology helps minimize short-term capital gains taxes. Say there's no way around it: you need to sell an asset. Maybe cash flows aren't enough to keep your portfolio completely balanced. Or you’re withdrawing funds for a major purchase. The question then becomes: which specific assets should be sold? The IRS and many brokers follow the simple script of "first in, first out," meaning your oldest assets are sold first.
  This approach is easier for your broker, and it can avoid more highly-taxed short-term capital gains. But it often misses the opportunity of selling assets at a loss, and harvesting those losses for potential tax benefits. So our algorithms take a more nuanced approach to selecting shares, and we call this technology TaxMin. TaxMin is calibrated to avoid frequent small rebalance transactions and seek tax-efficient outcomes, things like avoiding wash sales and minimizing short-term capital gains the same logic in reverse, or TaxMax as we call it. That's because when donating shares, it benefits you to choose the ones with the most gains, since any shares bought as a replacement will effectively have a reset tax bill.
• 4.Harvesting losses – When your taxable investments dip below their initial purchase price, we jump on the opportunity to “harvest” the theoretical loss and potentially lower your future tax bill. Life is full of ups and downs, and your investments are no different. At times, most notably during market downturns, the price of an asset may dip below what you paid for it.
  Tax loss harvesting takes advantage of these moments, selling taxable assets that fit this bill, then replacing them with similar ones so you stay invested.
  You can then use those harvested losses to shift taxes you owe now into the future.
