====== Why would tax schedule selection fail to work? ======

Tax schedules are normally assigned using these DynamicZip Routines:
  * [[dynamiczip:windows:dz_assign_customer_tax_schedules_window|DZ Assign Customer Tax Schedules window]]
  * [[dynamiczip:windows:dz_assign_site_tax_schedules_window|DZ Assign Site Tax Schedules window]]
  * [[dynamiczip:windows:dz_assign_vendor_tax_schedules_window|DZ Assign Vendor Tax Schedules window]]

Tax schedules assignment can also be triggered automatically while the user is entering transactions as well as when creating or editing customer, vendor and/or site addresses.

There are several things that can affect the DynamicZip [[dynamiczip:features:schedule_assignment:tax_schedule_selection|Automatic Tax Schedule Selection]]. 

===== DynamicZip Setup window =====

The following settings are made in the [[dynamiczip:windows:dynamiczip_setup_window|DynamicZip Setup window]].
==== Tax Schedule Selection section ====

  * If **Assign Tax Schedule** is __not__ selected, no tax schedules will be assigned.
  * If **Restrict by Country Code** is selected and the address has a country code that does not match either the Country Code Default for USA or for Canada as specified in the Import Settings section of the DynamicZip Setup window, no tax schedule will be selected for this address.
  * If **Select Default** is __not__ selected and multiple tax schedules exist that could be valid for the address's [[dynamiczip:glossary:tax_location|tax location]], no tax schedule will be selected for this address.
  * If **Update Blank and Zip ID's Only** is selected and the address currently has a tax schedule assigned to it that is not a [[dynamiczip:glossary:zip_code_tax_schedule|Zip Code Tax Schedule]] or a [[dynamiczip:glossary:statewide_tax_schedule|Statewide Tax Schedule]], no tax schedule will be selected for this address.
  * If **Exempt Always Valid** is selected and the address currently has a tax schedule assigned to it that has EXEMPT embedded in the ID, no tax schedule will be selected for this address.

===== DZ Customer Supplement window =====

The following setting is made in the [[dynamiczip:windows:dz_customer_supplement_window|DZ Customer Supplement window]].

==== Base Taxable Status====

  * If Base Taxable Status is set to **Default** or **Taxable**, only tax schedules that are **not** [[dynamiczip:glossary:exempt_tax_schedule|Exempt Tax Schedules]] will be considered valid for this customer.
  * If Base Taxable Status is set to **Exempt**, only tax schedules that are Exempt Tax Schedules will be considered valid for this customer.
  * If Base Taxable Status is set to **Ask** and:
    * no tax schedule is currently selected for this address and both taxable and exempt tax schedules exist for this location, then no tax schedule will be automatically selected.
    * a tax schedule is currently selected for this address but it is for a different zip, then the existing tax schedule will be ignored and no tax schedule will be automatically selected.
    * a tax schedule is currently selected for this address that has a matching zip then 
      * if the currently selected tax schedule is taxable, the Base Taxable Status will be considered to be Taxable and only tax schedules that are **not** Exempt Tax Schedules will be considered valid for this customer.
      * if the currently selected tax schedule is exempt, the Base Taxable Status will be considered to be Exempt and only tax schedules that are Exempt Tax Schedules will be considered valid for this customer.

===== Troubleshooting =====

As a general rule, the quickest way to determine why a customer's address card is not getting updated with a tax schedule ID is to follow these steps:
  - Open the [[dynamics:windows:customer_address_maintenance_window|Customer Address Maintenance window]] and select the customer and address ID for the address in question.
  - Select DZ Zip Address Lookup from the [[dynamiczip:glossary:additional_menu|Additional Menu]] and verify that the current address exists in the lookup window with the same ZIP Code and city name spelling. (If the address does not match, consider using the [[dynamiczip:windows:dz_customer_address_correction_window|DZ Customer Address Correction window]] to correct customer addresses.)
  - When the address is validated or corrected, click or tab into the Tax Schedule ID field. This should trigger DynamicZip to [[dynamiczip:features:schedule_assignment:tax_schedule_selection_criteria|select a tax schedule]] for this address. If this does not occur, open the Tax Schedule lookup window to see what choices exist for this address. Refer back to the above settings to determine why a tax schedule may not be automatically selected.
    - If clicking or tabbing into the Tax Schedule ID field is not triggering DynamicZip tax schedule selection, open the [[dynamiczip:windows:dz_trigger_setup_window|DZ Trigger Setup window]] and verify that the **Customer Address Maint Tax Schedule ID** trigger has not been disabled.
  - If there is only one valid choice for the address (or select default is selected in DynamicZip Setup) then open that tax schedule in the [[dynamics:windows:tax_schedule_maintenance_window|Tax Schedule Maintenance window]] and then select DZ Tax Schedule Supplement from the Additional Menu. In the [[dynamiczip:windows:dz_tax_schedule_supplement_window|DZ Tax Schedule Supplement window]] verify that the Geocode, Tax Location and Zip fields are not blank and that they are in sync with the tax schedule ID and the tax schedule description. If there appears to be a problem with this record, consider using the [[dynamiczip:windows:dz_rate_and_boundary_import_window|DZ Rate And Boundary Import window]] to refresh the tax details and schedules.
