Same Day ACH Resource Center

The ACH Rules change passed in May 2015 provided for the same-day processing and settlement of virtually any ACH payment. In September 2018, three new rules were approved to expand the capabilities of Same Day ACH as follows:

  1. Create a new processing window to allow ODFIs to submit Same Day ACH files until 4:45 p.m. ET – effective March 19, 2021 (Effective date changed from Sept. 18, 2020, as of March 12, 2019)
    • On May 9, 2019, the Federal Reserve Board published a Federal Register Notice (Off-site) requesting comment on potential modifications to the Federal Reserve Banks’ payment services to facilitate adoption of a later same-day automated clearing house (ACH) processing and settlement window.
  2. Increase the per-transaction dollar limit for Same Day ACH transactions to $100,000 – effective March 20, 2020
  3. Require that funds from Same Day ACH credits processed in the 10:30 a.m. ET window be made available by 1:30 p.m. on the RDFI’s local time – effective Sept. 20, 2019

This resource center presents information about Same Day ACH and the impact on FedACH® Services.
