Updates in W9 Form 2023

W-9 Form Draft 2023

The IRS has released a draft of the W-9 Form 2023, Request for Taxpayer Identification Number and Certification, which includes a new reporting requirement for flow-through entities.

Flow-through entities are entities that pass their income and losses through to their owners or members without paying corporate income tax. Examples of flow-through entities include partnerships, limited liability companies (LLCs), S corporations, and trusts.

The new reporting requirement requires flow-through entities to identify the presence of direct or indirect foreign partners, owners, or beneficiaries when they provide Form W-9 to another flow-through entity. This information will help the receiving flow-through entity determine whether it has any applicable reporting requirements, such as the requirement to complete Schedules K-2 and K-3 for foreign partners.

The new reporting requirement is intended to improve the IRS’s ability to track and enforce tax compliance among flow-through entities and their foreign partners, owners, and beneficiaries.
