Mortgage late fees and payment crediting, explained

Whether a late fee applies can turn on the day your servicer receives the payment. This page sets out what the CFPB says, and the specific payment-crediting rules in Regulation Z.

The short version: The CFPB says a servicer can charge a late fee if it receives your payment after the due date, even if you mailed it on time, and that most servicers go by the date of receipt rather than the postmark.^[1] Regulation Z requires a servicer to credit a periodic payment to your loan account as of the date of receipt, unless a delay in crediting results in no charge to you and no negative credit reporting, or unless the servicer accepts a payment that does not follow its written payment requirements, in which case it must credit that payment as of five days after receipt.^[2] A servicer may not charge a late fee that is attributable solely to an unpaid earlier late fee.^[2]

What this term means: Regulation Z defines a periodic payment for this rule as “an amount sufficient to cover principal, interest, and escrow (if applicable) for a given billing cycle.”^[2] A servicer, in our plain-language gloss, is the company that handles your payments and your account; it may not be the company that made or owns the loan.

What the CFPB says

A servicer can charge a late fee if it receives your payment after the due date, even if you mailed it on time. Most servicers do not go by the postmark on the envelope but by when they receive the payment, though some states have laws that may regulate servicers’ assessment of late fees.^[1]
The CFPB says to allow time for transit when you mail a payment.^[1]
If the servicer received your payment before the due date but delayed posting it until after the due date, the CFPB says charging a late fee is inappropriate. If the servicer refuses to remove the fee, you can file a complaint with the CFPB online or by calling (855) 411-CFPB (2372).^[1]

What Regulation Z requires of the servicer

The rules are in 12 CFR § 1026.36(c). They apply in connection with a closed-end consumer credit transaction secured by the consumer’s principal dwelling.^[2]

Situation	What § 1026.36(c) says
A periodic payment arrives	No servicer shall “fail to credit a periodic payment to the consumer’s loan account as of the date of receipt,” except when a delay in crediting does not result in any charge to you or in the reporting of negative information to a consumer reporting agency.^[2]
The payment leaves out fees	A payment still qualifies as a periodic payment even if it does not include amounts for late fees, other fees or non-escrow payments the servicer advanced for you.^[2]
A partial payment is held in suspense	A servicer that keeps a payment of less than a periodic payment in a suspense or unapplied-funds account must show the total held on your periodic statement, and when the funds add up to a periodic payment it must treat them as a periodic payment received.^[2]
The payment does not follow the servicer’s written instructions but is accepted	The servicer must credit the payment as of five days after receipt.^[2]
An earlier late fee went unpaid	A servicer shall not impose a late fee or delinquency charge for a payment if the charge is attributable solely to failure to pay a late fee on an earlier payment, and the payment is otherwise a periodic payment received on the due date or within any applicable courtesy period.^[2]

What the monthly statement must show

Under 12 CFR § 1026.41, a servicer of a covered closed-end mortgage must send a periodic statement for each billing cycle.^[3] The statement must group, near the top of the first page, the payment due date, the amount of any late payment fee and the date on which it will be imposed if payment has not been received, and the amount due.^[3] The statement must be delivered or mailed within a reasonably prompt time after the payment due date or the end of any courtesy period.^[3] The section exempts some loans, including reverse mortgages and loans serviced by a small servicer.^[3]

What these paragraphs do not set

Neither the CFPB page nor the Regulation Z paragraphs quoted above set the length of a grace period or the amount of a late fee. The CFPB points to state law, and your note and servicer statement show the terms that apply to your loan.^[1]

If you think the servicer misapplied a payment, our guide to notices of error and requests for information explains the written route, and why your payment may have changed covers other reasons a statement amount moves.

How to verify this yourself

Read the CFPB page (reference 1) and the regulation text for § 1026.36(c) and § 1026.41 in the eCFR (references 2 and 3). Your monthly statement and your payment records show the due date, the amount and the date the servicer says it received each payment. To check the person you are working with, use our guide to verifying a loan officer’s NMLS license. Our published standard covers how we check loan originators, and the Register shows that method; neither reviews a lender’s or servicer’s handling of your loan.

What this page does not cover

This page is general information, not legal advice. It does not say what late fee or grace period applies to any loan, covers no state law, and does not describe the rules for a loan in default or foreclosure. The CFPB page was last reviewed 2 February 2024. This page was last reviewed 6 October 2026.

Your next step

Keep proof of the date you paid and compare it with the date on your statement. If a late fee looks wrong, ask the servicer in writing to remove it. Then return to the Mortgage help library for related guides.
