Allspring and Vestmark build tax-aware models as BetaNXT adds Pave

Vestmark and Allspring said Allspring's active strategies will sit inside Vestmark's platform, which handles trading, rebalancing and tax overlays for advisors. BetaNXT said at Schwab IMPACT that it will add Pave Finance's portfolio software to its wealth management suite. One is a model-portfolio arrangement, the other a software integration.

The mechanics differ. The direction is the same. Pave's portfolio software goes into BetaNXT's suite. Allspring's strategies go into Vestmark's rebalancing and tax-overlay engine. In both cases a decision that shapes the account, what goes into the model and how it is adjusted for tax, happens upstream, inside software, not in a service purchased separately from a specialist.

For a practice that has been outsourcing that work, the change is concrete. Tax planning is the service high-net-worth practices farm out most, at 55%, ahead of trust administration at 40%, according to Cerulli's polling, which puts the average at three to four outsourced services per practice. A practice in that group now has a third option inside software it already runs, and needs to establish which parts of the tax job the overlay covers and which stay with the outside provider.

The routes to the advisor differ. Pave's portfolio software reaches advisors through a suite of wealth management tools, so the tooling can arrive without a separate buying decision at the practice. Allspring travels the other way: a manager's strategies enter the software, and the manager reaches the account through the model. That suggests the workflow owner decides which content appears in it, and the manager's job is to be among that content.

BlackRock's 2026 survey sets two numbers side by side: 41% of women called better tax outcomes a priority, against 12% of advisors who saw tax as a key client concern. More than one in four advised women said they plan to switch over taxes.

The policy side keeps adding detail. Washington's 9.9% millionaire tax applies only to income above $1 million, which would create a marriage penalty. Voters decide in November whether to repeal it under Initiative 645. Each of those details is a portfolio decision with a date attached, and an advisor who does not make it gets whatever the model does.

Scale is the argument for the model layer. A default inside the rebalancing engine reaches every account that runs the model. A tax service bought from a specialist reaches the clients a practice has enrolled. Reach decides this, and reach favors the platform.

Figures in the table come from Cerulli's polling of high-net-worth practices and BlackRock's 2026 survey of advised women and advisors.

Platform reach has conditions. Schwab's CEO pledged to keep serving RIAs under $100 million even though product thresholds exclude many sub-$100 million firms. If the tax overlay lives in the platform, access to it follows the same eligibility rules as the rest of the shelf. The smallest practices would then get the thinnest version, whatever their clients rank first.

What stays with the advisor is the work that does not repeat: the entity structure, the timing of a sale, the state a client moves to. The recurring adjustment inside accounts that run a model is the part the platform layer is taking, and it is the part a practice can standardize.

T. Rowe Price's alternatives distribution team grew from six in March to 13 now and is planned to reach 15 by year-end, with dedicated RIA and broker-dealer groups. TCW's TPAY asset-backed fund is nearing $600 million in assets and is available on Schwab, Fidelity and Pershing. Neither is a tax product. Both show managers building presence in the channel where models and overlays now sit, which is where Allspring just put its strategies.

Advisors, meanwhile, are not doing this work themselves. Capital Group's survey found 83% of advisors use AI weekly and only 13% use it beyond the basics. Adoption at that depth leaves the account-level work where it is, which is the work the platform side is now taking on.

Both arrangements are announcements rather than completed integrations. Adoption is the test. A model portfolio no advisor runs changes nothing about where the fee lands.

PWD's position: the tax decision is moving into the model, where the platform and the manager own it, and a practice that bills for tax planning separately has to show what it does that the rebalancing engine does not. Advisor-side tax judgment still counts where it settles a decision the software cannot.
