The Fifth Circuit Court of Appeals opinion in Sirius Solutions L.L.L.P. v. Commissioner may change our views of entity choice. If the decision holds up, partnerships will be able to effectively make the portion of limited partner income subject to self-employment tax whatever they want, including zero. This contrasts with the IRS position upheld by the Tax Court in Soroban Capital that treated all of the income of limited partners who were active in the business as self-employment income.

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.
