An ACH hold is a temporary bank-imposed delay on ACH (Automated Clearing House) credit availability — the period between when an ACH deposit is received and when funds are available for withdrawal or use. Hold periods are governed by Regulation CC (12 CFR Part 229) and Nacha operating rules. Businesses experiencing unexpected holds on ACH receipts should review their deposit account agreement. See federalreserve.gov/releases/h15 for funds availability rules and ftc.gov/tips-advice/business-center/guidance/complying-credit-card-act for related guidance.
When a business receives an ACH credit (electronic deposit), the bank may impose an availability hold before releasing funds. Unlike wire transfers (irrevocable, generally available same day), ACH credits can be returned by the originating bank for up to 2 business days (or 60 days for unauthorized ACH transactions under NACHA rules). This return risk is the primary justification for ACH holds. Regulation CC (12 CFR Part 229) — the Federal Reserve's funds availability rule — establishes maximum hold periods for various deposit types. For ACH credits specifically: Reg CC generally requires next-business-day availability for ACH credits to consumer accounts. However, banks may extend holds for large deposits, new accounts, repeatedly overdrawn accounts, or when there is reasonable cause to doubt collectibility. Nacha operating rules (nacha.org) govern the ACH network's timing: ACH originators submit files in batch windows; ODFI/RDFI settlement occurs through the ACH operator (Federal Reserve's FedACH or EPN). Standard ACH credit: next-day settlement. Same-Day ACH: same-day settlement available (per Nacha Same-Day ACH rules, effective 2016 and expanded 2021). Business impact: ACH holds create cash flow timing risk — especially for businesses that rely on rapid ACH receipts (payroll services, property management, SaaS billing). Understanding your bank's hold policies and building appropriate float into your cash management practice is essential. For large or recurring ACH receipts, many banks will negotiate expedited availability based on business relationship and account history. See federalreserve.gov for Regulation CC text and FDIC's compliance guidance at fdic.gov.
Under Regulation CC (12 CFR Part 229), banks generally must make ACH credit funds available by the next business day for consumer accounts. Exception holds (for large deposits over $5,525, new accounts, repeatedly overdrawn accounts, or reasonable collectibility concerns) can extend to 2-5 business days. Business account hold policies vary — check your deposit account agreement. Same-Day ACH credits may have shorter hold periods by bank policy.
An ACH hold is a temporary delay in fund availability — the money is there but not yet accessible. An ACH return is when the originating bank reverses the ACH transaction — the funds actually leave your account. Nacha allows ACH debits to be returned for up to 60 days for unauthorized transactions (R10/R11 return codes) and 2 days for most other return reasons. An ACH hold protects the bank against the possibility that a credit might be returned.
