ACH Dispute Management

ACH Dispute Management Software — Reg E Compliance for Community Banks

ACH disputes have a 10-business-day investigation window under Regulation E. Banks that apply the 45-day POS path to ACH disputes, miscalculate business days, or fail to issue provisional credit on time produce findings examiners identify in the first case they pull.

Reg E deadline paths for ACH disputes

ACH disputes have two applicable deadline paths, depending on account age at the time of the transaction. The path must be determined at intake — not estimated from memory.

Standard ACH — 10 business days

Applies when: ACH dispute on an established account, no POS or foreign-initiated transaction
Investigation deadline: 10 business days to complete the investigation
Provisional credit: Issue provisional credit by day 10 if extending the investigation

Watch for

The most common ACH dispute path. Banks that apply the 45-day POS path to ACH disputes have a deadline path error that examiners identify routinely.

ACH on a new account — 20 business days

Applies when: ACH dispute on an account open less than 30 days at the time of the transaction
Investigation deadline: 20 business days to complete the investigation
Provisional credit: Issue provisional credit by day 20 if extending the investigation

Watch for

New account status must be verified at the time of the transaction, not at the time of the dispute. Banks tracking account open dates manually frequently apply the wrong path.

Common ACH dispute exam findings

These findings appear in ACH dispute samples at banks using manual tracking. Each one is preventable with a system that applies the correct path automatically and enforces deadline timing from intake.

45-day POS path applied to a standard ACH dispute

The 45-calendar-day extended investigation path applies to POS and foreign-initiated transactions — not to standard ACH credits and debits. Banks that apply the 45-day path to ACH disputes are giving themselves more time than Regulation E allows. Examiners identify this when reviewing the deadline path documentation.

Account age not verified at time of transaction

The 20-business-day new account path applies when the account was open less than 30 days at the time of the disputed transaction — not at the time the dispute was filed. Banks that check account age at the time of the dispute may apply the wrong path.

Provisional credit issued late or not at all

ACH disputes extended beyond 10 business days require provisional credit by the end of day 10. Banks that issue credit on day 11 or 12 have a finding. Banks that extend the investigation without issuing provisional credit have a separate violation.

ACH dispute intake date recorded as business date

Reg E deadlines are counted in business days. Banks that record the intake date as a business date but count calendar days — or miscalculate business days around holidays — produce incorrect deadline dates. A one-day error is enough for a finding.

Frequently Asked Questions

What is the Reg E deadline for ACH disputes?

The standard Reg E investigation deadline for ACH disputes is 10 business days. If a bank needs more time, it must issue provisional credit by day 10 and may extend the investigation to 45 calendar days. For new account disputes — accounts open less than 30 days at the time of the transaction — the initial deadline is 20 business days.

What is the difference between ACH and debit card Reg E deadlines?

ACH disputes and debit card disputes both have a 10-business-day initial investigation window. The extended window diverges: ACH disputes extend to 45 calendar days. Debit card disputes for POS and foreign-initiated transactions may also extend to 45 calendar days. New account disputes on both ACH and debit card have a 20-business-day initial window extending to 90 calendar days.

What documentation does a bank need for ACH dispute compliance?

For each ACH dispute, a bank needs: the original intake record with the date received, the deadline path applied with documented basis including account age verification for new account disputes, all required Reg E letters with proof of send, provisional credit documentation if credit was issued, investigation notes referencing the ACH transaction records reviewed, and the final resolution decision with its documented basis.
