The ceiling
How high can a late fee go in New York?
Your contract decides. The rate above only applies when your terms are silent. Between businesses, an agreed late-interest rate or late fee replaces it, within two limits: the state's ceiling on agreed rates, and the rule that a late fee must compensate you rather than punish the customer.
New York's ceiling on an agreed rate wasn't part of our verified research, so check the state's usury law, or ask a lawyer licensed in New York, before writing the common 1.5%-a-month (18%) rate into your terms.
Late payment wording for a New York invoice
On your invoice
Payment is due by the date shown on this invoice. Late payments are subject to interest at 9% a year, the legal rate under N.Y. CPLR 5004.
This restates what New York law applies when your contract is silent. If your contract sets a rate, quote that instead. The wording doesn't say when interest starts, because that differs by state; the note at the top of this page covers it where New York law sets it.
