There are a few tax rules new for 2025 that may catch some individuals and their tax advisers by surprise. These changes have not received lots of attention either because they are overshadowed by related changes that are more significant, or they were enacted a few years back with a future effective date that arrives in 2025. This article covers changes for 2025 that you will want to be sure to share with clients to avoid surprises at a later date.

State Tax Planning with the “80/20 Company” Exclusion
Many multinational groups find that foreign-source dividends and other income earned by domestic affiliates are fully or partially subject to state income taxation, even where the federal system provides an exemption. This state-level “leakage” can be material – particularly in high-tax jurisdictions – and is often overlooked because the income appears sheltered at the federal level. For groups with predominantly foreign operations, a starting structure or a restructuring that causes one or more domestic affiliates to qualify as an “80/20 company” can substantially reduce or eliminate state taxation on that income.
