Vermont late fee law
When a contract is silent, Vermont's legal interest rate is 12% per year (9 V.S.A. § 41a(a); 12 V.S.A. § 2903(b)). The details, including what you may agree to instead, are below with citations.
Legal interest rate (type not classified)
9 V.S.A. § 41a(a); 12 V.S.A. § 2903(b)12%per year
We have not been able to confirm whether this figure is a contract-silent default, a litigation-only rate, or a ceiling. Do not rely on it without counsel.
9 V.S.A. § 41a(a) ('Legal rate of interest') provides that except as specifically provided, the rate of interest or sum allowed for forbearance or use of money shall not exceed 12% per annum (actuarial method) - this functions as both the general legal rate and the usury ceiling. Interest on judgments is likewise 12% per annum (12 V.S.A. § 2903). Verified via FindLaw's statute reproduction corroborated by Justia and Vermont Legislature search listings; the official legislature.vermont.gov site returned a TLS certificate error and could not be fetched directly - verify with counsel. Rate type not classified: 9 V.S.A. § 41a(a) is phrased as a ceiling ('shall not exceed 12%') and the recorded research notes it functions as both the general legal rate and the usury ceiling. Whether 12% ACCRUES on a silent contract or merely caps an agreed rate is not resolved by the recorded text. Verify with counsel before relying on this figure.
Agreed (contract) rates and caps
9 V.S.A. § 41aParties may agree to interest up to the 12% general cap of 9 V.S.A. § 41a(a); § 41a(b) lists numerous higher category-specific ceilings (e.g., retail installment contracts 18%/15%, retail charge agreements 21%, certain installment loans up to 24%/18% APR, negotiated rates for bank revolving credit). No broad corporate/commercial-borrower exemption from the cap was verified in this research - verify with counsel before relying on any rate above 12% in a B2B contract.
Prompt payment act
9 V.S.A. §§ 4002-4007; 12 V.S.A. § 2903(b)public+private-construction
Vermont's Prompt Payment Act (9 V.S.A. ch. 102, §§ 4001-4009) covers construction contracts (applied to private projects and generally to public construction; it is not a general trade-invoice statute). Owner payment is due within 20 days of the end of the billing period or of invoice delivery, whichever is later; delayed progress or final payments accrue interest from the 21st day at the rate established by 12 V.S.A. § 2903(b) (12% per annum) (9 V.S.A. § 4002(d)). Amounts wrongfully withheld can attract an additional 1% per month penalty, and the substantially prevailing party in an action may recover attorney fees.
Late-fee notes
No distinctive Vermont statute on flat late fees for commercial invoices was found; default principles apply (enforceable if agreed and reasonable, subject to the liquidated-damages/penalty doctrine). Note that because 9 V.S.A. § 41a caps charges for the 'forbearance or use of money' at 12% for most transactions, recurring percentage late charges on B2B invoices exceeding that rate carry usury-recharacterization risk - verify with counsel.
