Adhesion Wealth Adds Comprehensive, Ongoing Tax Management Overlay to RIA Platform

CHARLOTTE, N.C., June 28, 2026– Adhesion Wealth, a UMA administration and managed account platform, today announced that Tax Management Services (TMS), has been released on the platform as of June 28, 2026. TMS is designed to help RIAs deliver tax-aware portfolio transitions as well as personalized, always-on tax optimization, and tax-loss harvesting at scale—helping clients keep more of what they earn from investments.

Today’s investors are increasingly focused not just on gross performance, but also on after-tax returns. Research from Russell Investments using Morningstar data suggests that taxes can reduce taxable investment returns by roughly 1% annually (in some cases, closer to 2%) with the impact varying by asset class, portfolio structure, and market conditions.1 At the same time, many advisors continue to rely on manual or periodic tax-management processes that are very difficult to scale across a growing client base. As a result, advisors often face a tradeoff between delivering highly personalized tax strategies and operating their business efficiently.

“Advisors tell us one of the most frustrating situations they face is when they deliver great returns and then have to apologize for the tax bill it caused,” said Phill Rogerson, SVP, Head of RIA for Adhesion Wealth. “TMS has an established track record of addressing that problem for users of the AssetMark platform, and we’re excited to make those capabilities available to the RIAs who use the Adhesion Wealth platform.”

TMS currently supports almost $10 billion in assets for AssetMark clients and is designed with scalability, personalization, and tax savings in mind. By enrolling individual taxable accounts in TMS, advisors on Adhesion can provide clients with an automated daily tax optimization engine and the potential for daily tax-loss harvesting.

Rather than optimizing and harvesting losses monthly, quarterly, or annually as has been common practice for years, TMS can identify and act on harvesting opportunities when markets are open. This can be especially advantageous in volatile markets when prices are moving rapidly. Because TMS is automated and rules-based, advisors can extend this personalized service beyond high-net-worth clients to mass affluent and near-affluent households as well.

By simplifying implementation and improving the tax management process, TMS helps advisors onboard new clients with taxable assets and transition their accounts, while minimizing tax consequences. Advisors can enroll existing accounts with just a few clicks, enabling greater operational efficiency without adding unnecessary administrative burden.

“Historically, personalized tax management has been too labor intensive for an advisor to do it effectively at scale,” said Dave Studer, SVP of Wealth Solutions for AssetMark. “But now RIAs can run TMS on taxable portfolios across their entire business and use technology to execute strategies tailored to each individual client.”

TMS helps advisors incorporate continuous tax management directly into their portfolio management workflow. Integrated within the Adhesion Wealth platform, the solution is designed to support smoother transitions for new assets, improve tax efficiency, and help clients keep more of their investment returns over time. TMS includes a client-friendly proposal that helps advisors explain the benefits of having their accounts enrolled in TMS.

Tax Management Services will be available to RIAs using the Adhesion Wealth platform with assets custodied at Schwab or Fidelity starting June 29, 2026. Additional custodians will be added in the near future.

The Tax Management Services (TMS) is designed to improve the after-tax return for the client’s account, consistent with the risk/return profile of the investment models based on the selected tax sensitivity. TMS may cause the account to deviate from the investment models and can affect the risk profile and performance of the account. A higher tax sensitivity account setting can have a higher deviation from the investment models than a lower tax sensitivity. Adding TMS customizations to the account can impact the account’s tax and investment results. Actual tax management results are subject to change based on investment holdings, market conditions, timing, and other factors.
