No Tax Breaks for Sanctuary Cities Act

HR 1879, the "No Tax Breaks for Sanctuary Cities Act," denies tax-exempt status for bonds issued by jurisdictions classified as "sanctuary jurisdictions." A sanctuary jurisdiction is defined as a city or state that either restricts sharing immigration status information with federal authorities or fails to comply with federal detainer requests under immigration law. The bill requires the Treasury Secretary to publish an annual list of such jurisdictions within 180 days of enactment. This policy directly affects local governments meeting the definition by removing a key funding tool - tax-exempt municipal bonds - used for public projects like schools or infrastructure. The law applies to bonds issued after enactment and does not alter existing sanctuary policies themselves.
