A late fee is a charge added when a scheduled payment on a plan arrives after its due date. It should be set out in the written plan agreement before the customer signs, with the amount and when it applies. Under Regulation Z, charges for actual unanticipated late payment are not part of the finance charge (12 CFR 1026.4(c)(2)). Where a plan counts as consumer credit, any late payment charge goes in the disclosures (1026.18(l)). State laws on late fee amounts vary, so check your state before you set one.
What is a late fee on a payment plan?
It is a charge added to an installment that is paid after its due date. It gives the customer a reason to pay on time and covers some of the work of chasing a missed payment. It is separate from the price of what was sold. It only applies when a payment is late.
Does a late fee have to be in the agreement?
In practice, yes. A customer can only be held to a fee they agreed to. The written plan agreement should state:
- The amount, as a flat figure or a percentage of the missed installment.
- When it applies, such as a set number of days after the due date.
- Whether it can apply more than once to the same missed payment.
- How it is collected, for example added to the next installment.
Is a late fee a finance charge under Regulation Z?
No, as long as it is a true late charge. Regulation Z defines the finance charge as the cost of consumer credit as a dollar amount (12 CFR 1026.4(a)). Section 1026.4(c)(2) then excludes "charges for actual unanticipated late payment, for exceeding a credit limit, or for delinquency, default, or a similar occurrence."
The word "unanticipated" matters. A fee the customer pays only because a payment was actually late fits the exclusion. A charge built into the plan from the start is a different question.
Does a late fee need to be disclosed?
If your plan counts as consumer credit under Regulation Z, yes. The closed-end disclosures in 1026.18 include paragraph (l), late payment: "Any dollar or percentage charge that may be imposed before maturity due to a late payment, other than a deferral or extension charge." Those disclosures must be made clearly and conspicuously in writing, in a form the consumer may keep, before the transaction is consummated (1026.17(a)(1) and (b)).
Whether a plan counts as credit depends on the four-installment rule and how often you offer plans. See Truth in Lending Act.
| Late fee | Finance charge | |
|---|---|---|
| When it applies | Only after a missed due date | On the credit itself |
| Regulation Z section | Excluded by 1026.4(c)(2) | Defined in 1026.4(a) |
| Disclosure, if Reg Z applies | 1026.18(l) | 1026.18(d) |
How much can a late fee be?
That is mostly a state law question, and the answer varies by state and by type of business. Some states set caps on late charges in consumer contracts. Check the law where your customers live before you set an amount, and keep it the same for every customer on the same terms.
How do late fees and grace periods work together?
Most agreements give a few days after the due date before the fee applies. That window is the grace period. Write both into the same clause so the customer can see exactly when a payment becomes late.
