Arch, a platform designed for tracking private markets investments, has announced a new 1099 integration with Schwab Advisor Services. This integration enables the Arch platform to pull mutual client data, expanding its tax capabilities beyond K-1s to provide a complete tax view for its client base, which includes ultra-high-net-worth investors, single- and multi-family offices, and registered investment advisors (RIAs).
Ryan Eisenman, co-founder and CEO of Arch, stated that the company initially focused on streamlining K-1 collection. He noted that the integration with Schwab Advisor Services is a step toward building a comprehensive platform for managing all alternative investments in one location. Eisenman emphasized Arch’s commitment to customer feedback, indicating that the addition of 1099 capabilities directly addresses client needs.
By integrating with custodial platforms such as Schwab Advisor Services, Arch aims to make tax management across both alternative investments and traditional brokerage accounts more efficient and scalable. This move is designed to streamline coordination among investors, advisors, and accountants, allowing secure access to tax documents in a single location. The company anticipates this will reduce the time spent managing paperwork, improve data accuracy, and enhance overall tax-filing readiness for the nearly 500 allocators and wealth management firms utilizing its platform.
Alison Dooher, head of digital advisor solutions for Schwab Advisor Services, commented on the collaboration, stating that the partnership with Arch will streamline tax workflows for their shared clients. She highlighted that automatic access to 1099s through Arch’s platform can reduce administrative overhead, improve efficiency, and lead to better alignment and greater confidence for advisors and accounting teams.
Arch currently serves seven of the top 20 accounting firms, including RSM US LLP, and is used by thousands of tax accountants. Its end-to-end tax solution aims to enhance back-office efficiency by eliminating manual uploads, reducing versioning errors, and creating a clear audit trail for compliance and reporting. The platform automatically collects K-1s from fund managers and 1099s from custodians, extracts and validates key metadata for accurate organization, and maintains a digital repository for both anticipated and received forms. Users receive daily digest emails summarizing updates, while the platform actively tracks missing documents and automates reminders.
Clients are reportedly benefiting from the more seamless experience provided by these scaled solutions. Mike Mordoh, Vice President, Head of Operations at Sequoia Financial Group, acknowledged Arch’s contribution to an exceptional client experience. He noted that the new 1099 integration with Schwab Advisor Services streamlines tax season by securely organizing investment documents.
Arch, which supports $280 billion in private assets across 480 allocators—including 180 single-family offices, 100 RIAs and multi-family offices, four of the top 20 global banks, and seven of the top 20 accounting firms—plans to continue expanding its products. The goal is to deliver a fully digital, consolidated tax workflow to empower professionals in serving investors and facilitating investment decisions.
