Nacha Raises Same Day ACH Limit to $10 Million, Expanding Corporate Use Cases

  • Nacha approved a rule change increasing the Same Day ACH per payment limit to $10 million, effective September 17, 2027.
  • This is the third increase since Same Day ACH's inception, following prior raises to $100,000 in 2020 and $1 million in 2022.
  • Q1 2026 saw 403 million Same Day ACH payments valued at $1.1 trillion, up 23.6% and 22.1% year-over-year respectively.
  • Nacha anticipates expanded use for invoice/tax payments, insurance claims, payroll funding, merchant settlement, and cash concentration.

This limit increase positions Same Day ACH to compete more directly with wire transfers for large corporate payments, reflecting growing demand for faster settlement across industries. The change comes amid sustained growth in ACH volume—1.4 billion payments worth $3.9 trillion in 2025—and underscores the network's evolving role in high-value transactions.
