ACH Processing Rules

New ACH Processing Rules.

Effective September 15, 2017.

This new rule change is commonly referred to as Phase 2 or 'ACH same day settlement'. In summary, this phase addresses the process of posting electronic (ACH) withdrawal transactions, and specifically how quickly these transactions may post. In some cases, debit transactions (payments that are withdrawn from your account electronically) may be initiated (originated) and posted to your savings or checking account on the same day. This means that some electronic (ACH) withdrawal transactions could post to your account on the same day they are initiated.

Below are some examples of ACH transactions that could be affected by this change:

  • Writing a check at a department store or other merchant retailer
  • Paying your bills online or by phone if electing to pay directly from your savings or checking account.

What can I do to prepare for these changes?

Review and make changes to any automatic or recurring payments that you may have scheduled, to ensure funds are available in your account on the date you authorized the payment. This may require you to contact the service providers directly to change the date of the withdrawal. This will help avoid possible overdraft fees or service interruption.

How might this affect me?

Payments, purchases, or charges (electronic withdrawals from your account) by merchants or vendors, may post on the same day as originated. (Includes online or payments by phone for utilities, mortgage, etc., or checks that are converted to electronic payments.)

Will this appear differently in my account history?

Your transaction descriptions will not change. You may see transactions post to your account during the day or on the same day they are initiated.

Will this affect payments made using my credit card or debit card?

No. Payments using your debit card or credit card will not be impacted by this rule change.
