(IND) Determining and Calculating Excise Duty, Sales Tax, VAT, and Customs Duty

You can determine tax default parameters and calculate taxes online or in batch by calling two common routines—the tax determination function and the tax calculation function. When you determine tax defaults and calculate taxes online, the calling application must use rowsets. When you determine tax defaults and calculate taxes in batch, the calling application must use temporary tables.

This chapter discusses how to:

Call the Tax Determination process.
Call the Tax Calculation process.

Calling the Tax Determination Process

The Tax Determination process is a common routine that determines tax applicability, tax calculation codes, and component codes. Calling applications can call this function in batch mode, or online from the header or transaction line level. Calling this function online from the header level enables the transaction to track at the header level tax determination information that might not vary by transaction line, such as the vendor tax transaction type.

When the calling application passes tax determination information (such as vendor tax transaction type), the tax determination function does not overwrite the value initially passed.

This section provides an overview of the Tax Determination process, and discusses:

Preparations necessary before calling the Tax Determination process.
Reapplying default tax parameters.
Validating transaction lines.
Tax Determination input parameters.
Tax Determination output parameters.

Understanding the Tax Determination Process

When an application calls the tax determination function, the process compares the ship from and ship to country, and performs the following for each row the calling application passes:

If the ship from and ship to country are not the same, the system marks the row as not applicable for sales tax or VAT.
If the tax transaction type is defined as Interunit Transfer, no sales tax, VAT, or customs duty are applicable.
If the ship from and ship to country are the same:
1. The process checks the Business Unit Tax Applicability table to determine whether the business unit is excise duty applicable, sales tax applicable, VAT applicable, or customs duty applicable.
  
  If the business unit is not applicable for either type of tax, the function marks the appropriate tax applicable flags as No and exits.
2. If the business unit is tax applicable, the process checks the trading partner tax applicability table to determine if the trading partner is excise duty applicable, sales tax applicable, VAT applicable, or customs duty applicable.
  
  If tax is applicable, the process retrieves the default tax transaction type and the trading partner's tax category. If the tax is not applicable to the trading partner for either type of tax, the function marks the appropriate tax applicable flags as No and exits.
3. If both the business unit and the trading partner are tax applicable, and if an item or product ID were provided by the calling application, the process checks the item or product tax applicability table to determine if the item or product is excise duty applicable, sales tax applicable, VAT applicable, or customs duty applicable.
  
  If tax applicable, the process retrieves the item tax category. If the item or product is not applicable for any type of tax, the function marks the appropriate tax applicable flags as No and exits.
4. If the business unit, trading partner, and item or product (if applicable) are all excise duty applicable, the process:
  
  Checks the Tax Determination table to determine the tax calculation code applicable for excise duty.
  
  Accesses the Tax Rate Code table and inserts a row into the Tax Detail child rowset for every tax detail row associated with the tax calculation code.
5. If the business unit, trading partner, and item or product (if applicable) are all sales tax or VAT applicable, the process:
  
  Determines the rate derivation and reporting tax authorities.
  
  Checks the Tax Determination table to determine the tax calculation code applicable for sales tax or VAT.
  
  Accesses the Tax Rate Code table and inserts a row into the Tax Detail child rowset for every tax detail row associated with the tax calculation code.
6. If the business unit, trading partner, and item or product (if applicable) are all customs duty applicable, the process:
  
  Checks the Tax Determination table to determine the tax calculation code applicable for customs duty.
  
  Accesses the Tax Rate Code table and inserts a row into the Tax Detail child rowset for every tax detail row associated with the tax calculation code.

Preparing to Call the Tax Determination Process

Prior to calling the Tax Determination process, the calling application must determine which business unit value the tax determination will use, and determine the ship from country, ship from state, ship to country, and ship to state.

Determining the Business Unit for Tax Determination

Refer to the following table to determine the correct business unit to use for tax determination:

Application	Use Business Unit
Inventory	Ship From Inventory
Order Management	If a Ship From Inventory business unit exists on the schedule line, use the Inventory business unit. If no Ship From Inventory business unit exists on the schedule line, use the Order Management business unit.
Billing	Bill Header: Billing business unit (used only for online manual bill entry)
	Bill Line: If an Inventory business unit exists, use the Inventory business unit. If no Inventory business unit exists, use the Order Management business unit. If no Order Management business unit exists, use the Billing business unit.
Receivables	Group Control: Use the Receivables business unit (used for online pending item entry only).
	Pending Item: If an Order Management business unit has been specified, use the Order Management business unit. If no Order Management business unit has been specified, but a Billing business has been specified, use the Billing business unit. If neither an Order Management business or a Billing business has have been specified, use the Receivables business unit.
Purchasing	If an Inventory business unit has been defined for the ship to location, use the Inventory business unit. If no Inventory business unit has been defined for the ship to location, use the Purchasing business unit.
Payables	Header: Payables business unit (for online manual entry only).
	Transaction Lines: If an Inventory business unit has been defined for the ship to location, use the Inventory business unit. If no Inventory business unit has been defined for the ship to location, use the Payables business unit.

Determining the Ship From Country and State

Refer to the following table to determine the correct ship from country and state to use:

Application	Use Ship From Country, State
Inventory and Order Management	If an Inventory business unit is available, use the Inventory business unit location country and state. If no Inventory business unit is available, use the Order Management business unit location country and state.
Billing	If an Inventory business unit is available, use the Inventory business unit location country and state. If no Inventory business unit is available, use the Order Management business unit location country and state. If no Order Management business unit is available, use the Billing business unit location country and state.
Receivables	If an Order Management business unit is available, use the Order Management business unit location country and state. If no Order Management business unit is available, but a Billing business is available, use the Billing business unit location country and state. If neither an Order Management business or a Billing business is available, use the Receivables business unit location country and state.
Purchasing and Payables	Use the country and state from the ordering vendor location.

Determining the Ship To Country and State

Refer to the following table to determine the correct ship to country and state:

Application	Use Ship From Country, State
Inventory, Order Management, Billing, and Receivables	Use the Ship To Customer country and state. For InterUnit transfers, use the destination business unit location country and state.
Purchasing and Payables	Access the ship to location. If there is an Inventory business unit specified for the ship to location, use the Inventory business unit location country and state. If there is no Inventory business unit specified for the ship to location, use the ship to location country and state.

Application

Use Ship From Country, State

Inventory, Order Management, Billing, and Receivables

Use the Ship To Customer country and state.
For InterUnit transfers, use the destination business unit location country and state.

Purchasing and Payables

Access the ship to location.

If there is an Inventory business unit specified for the ship to location, use the Inventory business unit location country and state.
If there is no Inventory business unit specified for the ship to location, use the ship to location country and state.

Reapplying Default Tax Parameters

If you make changes to the trading partner information, item or product ID, tax transaction type, or to any of the tax calculation codes, you are required to call the tax determination function again to reapply defaults based on the new values.

Preparing Fields for Updated Tax Parameters

The calling application must blank out the fields related to modified information prior to calling the tax determination function.

Change To	Calling Application Responsibilities
Trading Partner	If the excise duty, custom duty, sales tax, or VAT calculation code is not equal to the default tax calculation code, issue a warning that the tax determination function will overwrite the tax calculation code. Blank out the tax calculation codes, use assessable value flag, tax form code, and service tax flag. Delete all rows from the tax detail table for the affected transaction lines. Blank out excise duty, custom duty sales tax, and VAT applicability flags, the tax authorities, tax transaction type, and trading partner excise, customs, sales tax, and VAT categories. Note. Taxability rules may differ for trading partners. Consequently, the Tax Determination process may blank out fields related to the item (when the new trading partner is not taxable), or populate fields related to the item (when the new trading partner is taxable), even if the item did not change.
Ship To Location (for procure to pay) or Ship From Location (for order to cash)	If the excise duty, customs duty, sales tax, or VAT calculation code is not equal to the default tax calculation code, issue a warning that the tax determination function will overwrite the tax calculation code. Blank out the tax calculation codes, use assessable value flag, tax form code, and service tax flag. Delete all rows from the tax detail table for the affected transaction lines. Blank out excise duty, customs duty, sales tax, and VAT applicability flags, tax location reporting currency, and tax authorities. When the Item/Product Kit Use flag is set to I (item), blank out excise UOM, excise tax item type, item excise and tax categories, and chapter ID. Zero out assessable value. Note. The last step is applicable only when items are specified on the transaction line. Item tax applicability may be specified by Inventory business unit, or at the item master level. If you change the ship to or ship from location, the Tax Determination process might use a different business unit to determine taxability—a different Inventory business unit, an Inventory business unit where a product-specific business unit was previously used, or a product-specific business unit where an Inventory business unit was previously used. Consequently, the Tax Determination process must recheck the tax applicability of the item, even if the item had not changed. Note. Taxability rules may differ for business units. Consequently, the tax determination function may blank out fields related to the trading partner or item (when the new business unit is not taxable), or populate fields related to the trading partner or item (when the new business unit is taxable), even if the trading partner or item did not change.
Item or Product Kit	If the excise duty, customs duty, sales tax, or VAT calculation code is not equal to the default tax calculation code, issue a warning that the tax determination function will overwrite the tax calculation code. Blank out the tax calculation codes, use assessable value flag, tax form code, and service tax flag. Delete all rows from the tax detail table for the affected transaction lines. Blank out the excise duty, customs duty, sales tax, and VAT applicability flags, excise UOM, excise tax item type, item excise, customs and tax categories, and chapter ID. Zero out assessable value.
Tax Transaction Type	If the excise duty, customs duty, sales tax, or VAT calculation code is not equal to the default tax calculation code, issue a warning that the tax determination function will overwrite the tax calculation code. Blank out the tax rate codes, use assessable value flag, tax form code, and service tax flag. Delete all rows from the tax detail table for the affected transaction lines. Blank out the tax authorities and the excise duty, sales tax, and VAT applicability flags.
Tax Calculation (Rate) Code	If tax calculation code was blank, issue a warning that the tax determination function will overwrite the tax calculation code. If tax calculation code was not blank, blank out the use assessable value flag and tax form code. Delete all rows from the tax detail table for the affected transaction lines.

Calling the Tax Calculation Process

The Tax Calculation process is a common routine that performs sales tax, VAT, customs duty, and excise duty tax calculations and returns tax and tax basis amounts. This function accepts as input one or more rows of transaction line data, plus one or more child rows of tax detail for each transaction line, using rowsets for online processing, and temporary tables for batch processing.

This section provides an overview of the Tax Calculation process, and information about:

Tax calculation input parameters.
Tax calculation output parameters.

Understanding the Tax Calculation Process

The tax calculation function performs the following for each line:

Obtains from the exchange rate table the exchange rate between the base currency and the tax location reporting currency.
If required (if the transaction unit of measure is not equal to the excise unit of measure), obtains from Item Units of Measure table the factor for converting the transaction unit of measure to the excise unit of measure.
Converts transaction line amounts from transaction currency to base currency.
Converts transaction line base currency amounts to tax location reporting currency
For each row in the child tax detail table, performs the following tax calculations using the tax location reporting currency amounts:
1. If the calculation scheme is defined as an ad hoc amount, sets the tax amount to the tax rate amount from the tax calculation code.
  
  Converts the tax rate amount from tax calculation code currency to reporting currency, base currency, and then transaction currency.
2. If the calculation scheme is defined as quantity:
  
  Converts the quantity into the excise unit of measure.
  
  Calculates the tax by multiplying the tax rate amount (in transaction currency) from the tax rate code by the quantity in the excise unit of measure.
3. If the calculation scheme is defined as percentage:
  
  Calculates the taxable basis amount based on whether the assessable value must be used, whether freight and/or miscellaneous charges must be included plus any other tax component amounts (including excise tax if sales tax or VAT is being calculated) that must be included.
  
  Calculates the tax amount by applying the tax rate percent against the taxable basis.
4. Converts the resulting tax and tax basis amounts from transaction currency back to base currency.
5. Converts the base currency tax and tax basis amounts to tax location currency.
