California caps interest under article XV, section 1 of the state Constitution at ten percent per year for loans made primarily for personal, family, or household purposes, and for other loans at the higher of ten percent or five percent above the Federal Reserve Bank of San Francisco rate. Lenders licensed under the California Financing Law, Cal. Fin. Code §22000 et seq., are exempt, which is why the ceiling bites hardest on private parties. A usurious note forfeits all interest, and Cal. Com. Code §3118 gives the holder six years to sue.
New York runs two tiers. General Obligations Law §5-501 fixes civil usury at sixteen percent, and Penal Law §190.40 makes anything above twenty-five percent criminal usury. Corporate makers cannot raise the civil defense under GOL §5-521(1), but the Court of Appeals confirmed in Adar Bays, LLC v. GeneSYS ID, Inc. that they may still plead criminal usury. The remedy is severe: the note is void and the lender loses principal as well as interest under GOL §5-511.
Texas applies usury rules to commercial paper as well as consumer paper, which surprises out-of-state lenders. Tex. Fin. Code §302.001 sets the default maximum at ten percent, while a written agreement may reach the ceiling published under Chapter 303, generally eighteen percent and higher for qualifying commercial loans. Penalties under §305.001 run to three times the excess interest.
Florida declares interest above eighteen percent usurious under Fla. Stat. §687.02 for loans at or below the statutory tier and allows up to twenty-five percent above it. Crossing twenty-five percent triggers §687.071, the criminal usury statute, and §687.04 strips the lender of all interest. Points, commissions, and origination fees count toward the rate in Florida as in New York, so a note that looks compliant can still be usurious once the charges are aggregated. Delaware sits at the other end, removing any ceiling on larger non-consumer loans under 6 Del. C. §2301.
