Income Excludability Under Section 115 and Deductible Contributions Under Section 170

This Private Letter Ruling (PLR-111952-25) determines that a taxpayer organization formed by a county qualifies for income excludability under IRC Section 115(1) as an essential governmental function, and that contributions to it are deductible under Section 170 as gifts to a political subdivision. The organization is governed by a board composed of the county treasurer, chief executive officer, and president of the legislative body, plus appointed municipal representatives, all serving without compensation. The IRS applied the six-factor test from Revenue Ruling 57-128 and precedent from Revenue Rulings 77-261, 90-74, and 75-359 to conclude the organization functions as a wholly-owned instrumentality of the county with no private interests benefiting.

Frequently asked

Where does the IRS publish guidance? +

The IRS publishes through several channels: Revenue Rulings (binding interpretations), Revenue Procedures (procedural guidance), Notices (advance signal of upcoming guidance), Private Letter Rulings (binding only on the requesting taxpayer), and Internal Revenue Bulletins (the official compilation). Major guidance also appears in the Federal Register for formal rulemaking. The IRS website hosts all of these with PDFs of original documents.

How do state DOR letter rulings work? +

State Departments of Revenue issue letter rulings interpreting state tax law for specific taxpayer transactions. Most are binding only on the requesting taxpayer but signal state interpretation for similar facts. New York, California, and Texas publish particularly active letter ruling streams covering nexus, apportionment, sales and use tax, and franchise tax issues. Cross-state advisers track these closely.

What is sales tax nexus? +

Sales tax nexus is the connection between a business and a state sufficient to require collection of state sales tax. The Wayfair decision in 2018 established economic nexus thresholds (typically $100,000 in sales or 200 transactions per year) without requiring physical presence. Each state has set its own threshold and enforcement approach. Multi-state remote sellers track all 45 states with sales tax.

How does FATCA differ from CRS? +

FATCA is US tax law requiring foreign financial institutions to report accounts held by US persons to the IRS. CRS (Common Reporting Standard) is the OECD-developed automatic exchange framework adopted by 100+ countries. CRS reporting is mutual: each participating country exchanges account data with every other participant. FATCA flows only one direction (to the IRS). Compliance teams typically maintain both systems in parallel.

Where do international tax authorities publish guidance? +

HMRC publishes Manuals, Briefs, and consultation documents on gov.uk. Canada's CRA publishes through Income Tax Folios and Technical Interpretations on canada.ca. Australia's ATO uses Taxation Rulings, Practice Statements, and ATO Interpretative Decisions on ato.gov.au. South Africa's SARS publishes Binding General Rulings, Interpretation Notes, and Practice Notes on sars.gov.za. Each authority has its own classification system.
