    FAR 32.609—Delays in receipt of notices or demands.

    Plain-English Summary

    FAR 32.609 addresses what happens when a Government demand letter or other notice that starts interest accrual is delayed in reaching the recipient. The section covers delays caused by the Government, including undue delay after the letter is dated at the originating office and delays in the mail, and it explains how those delays affect the date the debt is considered to exist and when interest begins to accrue. Its purpose is to prevent a contractor or debtor from being charged interest for a period when the Government’s own delay kept the demand from being received. In practice, this means the contracting officer or other responsible official must look at the actual circumstances of delivery and adjust the debt date and interest start date to something fair and reasonable. The rule is narrow but important because it protects against unfair interest charges while still preserving the Government’s right to collect valid debts and interest once notice is effectively received.

    Key Rules

    Government delay can shift accrual

    If the Government delays delivery of a demand letter, the original date on the letter does not automatically control interest accrual. The debt date and interest start date must be extended to a fair and reasonable time under the circumstances.

    Applies to demand letters and notices

    The rule covers delays in receipt of notices or demands that are used to establish the debt and begin interest accrual. It is aimed at situations where the timing of the Government’s notice affects the debtor’s liability for interest.

    Undue delay is the trigger

    The section specifically addresses delay caused by the Government, such as an undue delay after the letter is dated at the originating office or delay in the mail. The key question is whether the Government’s actions or transmission process postponed receipt.

    Fair and reasonable adjustment required

    When delay exists, the date of the debt and the start of interest must be adjusted to a fair and reasonable date based on the facts. This is not a fixed formula; it requires judgment about when the notice should reasonably be treated as received.

    Interest cannot run unfairly

    The Government may not charge interest for a period attributable to its own delay in sending or delivering the demand. Interest should begin only when the debtor had a fair opportunity to receive the notice.

    Responsibilities

    Contracting Officer

    Determine whether Government-caused delay affected receipt of the demand letter or notice, and if so, adjust the debt date and interest accrual date to a fair and reasonable time.

    Government Originating Office

    Issue demand letters promptly and avoid unnecessary delay between dating the letter and forwarding it for delivery.

    Mail/Delivery Process or Other Government Transmission Channel

    Transmit the notice without avoidable delay; if delay occurs in the Government-controlled delivery process, that delay must be considered in setting the effective date.

    Contractor or Debtor

    Review the timing of receipt and challenge any interest calculation that appears to include periods of Government-caused delay.

    Practical Implications

    1

    Interest calculations are not purely mechanical; the actual delivery timeline matters when the Government is responsible for delay.

    2

    Contractors should keep envelopes, postmarks, email timestamps, and receipt records to show when a demand was actually received.

    3

    Contracting officers should document the basis for any adjusted debt date so the interest calculation is defensible.

    4

    A common pitfall is using the date on the demand letter as the interest start date even when the letter sat in the originating office or was delayed in transit.

    5

    This section helps prevent unfair interest charges, but it does not eliminate interest altogether once a fair receipt date is established.

    Official Regulatory Text

    If interest is accrued based on the date of the demand letter and delivery of the demand letter is delayed by the Government ( e.g. , undue delay after dating at the originating office or delays in the mail), the date of the debt and accrual of interest shall be extended to a time that is fair and reasonable under the particular circumstances.
