The rankings, after-tax yields, compiled tables, charts and the downloadable files we publish (for example snapshot.json, bill_auctions.csv, auctions.csv, yield_snapshots.csv and fund_vs_bill_yields.csv) are licensed under the Creative Commons Attribution 4.0 International license (CC BY 4.0).

Underlying source data

• U.S. Treasury data (Fiscal Data auctions, TreasuryDirect results, Daily Treasury Bill Rates) is a work of the U.S. federal government and is in the public domain in the United States. See USA.gov: Government works.
• Fund yields and U.S. government obligations percentages are facts published by each fund issuer; we link the issuer page or tax document next to every figure. The issuers' own documents remain subject to their terms.
• State income tax rates come from the Tax Foundation, 2026 State Individual Income Tax Rates and Brackets (rates as of Jan 1, 2026); please also credit the Tax Foundation if you reuse the bracket tables.

No warranty

The data is provided as is, without warranty. Yields change daily and source data can be revised. Check the linked source before relying on any figure. Nothing on StateYield is financial or tax advice.
