Electronic Tax Payment File Set Up

To post payments electronically, the input file must be in Microsoft Access format. The database may have any name, but it's suggested that it have a descriptive name for ease of use.

The table within the database must be named "pay" and must contain the following six fields:

  1. LenderName - text field
  2. Lender - long integer field designating the lender number
  3. Loan - single precision field designating the loan number
  4. PARID - double precision field designating the parcel ID
  5. SEQ - long integer field designating the bill number *REQUIRED
  6. Amount - currency field designating the payment amount *REQUIRED

The amount field must have any decimal in place - example $101.55 should be shown as 101.55, not 10155.

Once the final record in the input file has processed, if there are any rejected payments, you will receive a report that will show the bill number, parcel number, lender, loan number, amount rejected and the reason for rejection.
