Current Behavior:

When a tax certificate is generated in TO4 and the grace period end date falls on a weekend, the system automatically extends the grace period to the following business day. As a result, the tax certificate is issued without reflecting any penalties and interest — even if the payment will not actually be made on that day.

Requested Functionality:

Add a configurable setting in TO4 that allows the client to disable the grace period specifically for tax certificate issuance. This setting should:

Apply only to tax certificates — not to standard payment processing or other system functions.

Allow the tax certificate to display the correct penalties and interest regardless of whether the grace period falls on a weekend or holiday.

Be toggleable (on/off) so the client can control when this behavior is applied.
