SEI LifeYield

SEI LifeYield sells software that manages taxes across all of a household's investment accounts rather than one account at a time. Its customers are wealth management firms and other large financial services companies that build the tools into their own advisor platforms; the company calls the approach a unified managed household.

The technology is offered as separate APIs and as a ready-made overlay with its own interface and client proposals and reports. Asset location recommends which account each holding should sit in and scores a household's tax efficiency from 0 to 100. A multi-account rebalancing engine coordinates taxable, tax-deferred and tax-free accounts, with sell constraints and gain budgets. Other modules handle tax harvesting, tax-aware transitions into new portfolios, the order and amount of withdrawals in retirement, retirement income sourcing and Social Security claiming strategy. Firms can also use the tools on held-away assets to show prospects the potential tax difference.

LifeYield is based in Boston. SEI Investments Company (NASDAQ: SEIC) acquired it in December 2024, and it now operates as SEI LifeYield, LLC, an unregulated SEI subsidiary; SEI had earlier added LifeYield's household capabilities to the SEI Wealth Platform. Pricing is not published.
