If your joint account is with your spouse and you file your taxes jointly, you can enable TLH+. When you enable TLH+ on your Betterment account, you’ll be asked for your spouse’s account information so that we can look across both your accounts for opportunities to harvest losses, while seeking to prevent wash sales in your Betterment accounts. If you already have TLH+ turned on, you’ll need to turn it off and set it up again to include your spouse. Learn more about TLH+.
