This article describes how to set up and use Italian sales tax books and Italian sales tax book sections.

According to Italian fiscal legislation, every value-added tax (VAT) transaction must belong to a tax book (Libro IVA) that you use for tax reporting. To fulfill these legislative requirements, Dynamics 365 Finance implements Italian sales tax books. Sales tax books can be different types. You must specify the sales tax book type to help guarantee that all sales and purchase transactions are included on the Italian sales tax payment report. You can keep as many sales tax books of the Sales and Purchase types as you require. You can divide each tax book into multiple tax book sections (Sezionale IVA). You must sequentially number (without gaps) and order all sales tax transactions by posting date. A tax book section is equivalent to a number sequence for the Italian sales tax voucher number (Protocollo IVA) that you always apply during posting to help guarantee chronological order by posting date.

Prerequisites

The following table shows the prerequisites that must be in place before you start.

Category	Prerequisite
Setup: Legal entity	The primary address of the legal entity must be in Italy. (Select Organization administration > Organizations > Legal entities > Addresses > Country/region.)
Setup: Number sequences	Set up as many number sequences as you require to cover all the required types of sales tax transactions. (Select Organization administration > Number sequences > Number sequences.) All these number sequences must be continuous and must have Company scope.
Setup: Journal names	Set up the required journal names. (Select General Ledger > Journal setup > Journal names or Project management and accounting > Setup > Journals > Journal names.) On the General FastTab, in the Sales tax section, in the Italian sales tax book field, specify one of the following values: Not included – Select this value for invoices and credit notes that come from countries/regions that are outside the European community. Purchase – Select this value for purchase invoices and credit notes. Sales – Select this value for sales invoices and credit notes. Empty – Select this value for all other types of transactions. In some cases, the system sets the Italian sales tax book field automatically, based on the Journal type value. For example, if you set the Journal type field to Invoice register, the Italian sales tax book field is set to Purchase by default.
Setup: Module parameters	To make vouchers follow the number sequences of the related invoices and credit notes, select the Reuse numbers check box when you define the number sequences for those invoices and credit notes. You can find this check box on the Number sequences tab of the following pages: Accounts receivable parameters Accounts payable parameters Project management and accounting parameters For example, on the Accounts receivable parameters page, on the Number sequences tab, select the Reuse numbers check box for Free text invoice voucher to synchronize number allocation for free text invoice vouchers and free text invoices. In the Italian localization, corrections to the Italian sales tax payment report for an already settled sales tax period aren't supported. So on the General ledger parameters page, on the Sales tax tab, set the Special report Include corrections option to NO.
Setup: Sales tax settlement period	For a Sales tax settlement period that you set up and use for sales tax accounting, specify the parameters, Include zero lines and Include reverse transactions to determine whether zero and reverse transactions are included into sales tax books by default. Values from these parameters are used as default values during the sales tax settlement process. For each period interval of the sales tax settlement, these parameters can be changed specifically during the sales tax settlement process. If the sales tax settlement process is run in batch, Finance applies the default parameter values of Include zero lines and Include reverse transactions parameters from the Sales tax settlement period setup. You can see the values of the Include zero lines and Include reverse transactions parameters that were used for each closed period interval of sales tax settlement period on the Sales tax payment page. You can't change the values of the parameters Include zero lines and Include reverse transactions for the closed period interval of the sales tax settlement period. Including zero and reverse transactions to the sales tax books might impact the page numbering in the report.

Set up sales tax books

Use sales tax books for sales tax reporting. To set up Italian sales tax books, go to Tax > Setup > Sales tax > Italian sales tax books. The following table describes the fields that are available on the Italian sales tax books page.

Field	Description
Sales tax book	Enter the ID of the sales tax book.

It isn't included on the final fiscal tax book reports.
Settlement period	Select an existing sales tax settlement period. When you print a sales tax book, if you select the Update check box on the Sales tax payment page, the date in the From date field is compared to the selected settlement period. The settlement period also identifies which sales tax books and sales tax book sections must be closed when a sales tax settlement is updated for a settlement period.

Set up sales tax book sections

Sales tax book sections act as a repository where you post ledger transactions according to their nature. The sales tax book sections drive the voucher numbering. To set up Italian sales tax book sections, select Tax > Setup > Sales tax > Italian sales tax book sections. The following table describes the fields that are available on the Italian sales tax book sections page.

Sales tax book	Select one of the existing sales tax books to attach the sales tax book section.
Sales tax book section	Enter the ID of the sales tax book section.
Name	Enter a description of the sales tax book section.
Number sequence code	Select the number sequence code for the sales tax book section. The number sequence code that you select depends on the type of sales tax book that the sales tax book section is attached to: For a sales tax book of the Purchase type: Select number sequence codes that are defined for purchase invoice vouchers or purchase credit note vouchers on the Accounts payable parameters page, or number sequence codes that are used on the Journal names page for vouchers that have the Italian sales tax book field set to Purchase. For a sales tax book of the Sales type: Select number sequence codes that are defined for sales invoice vouchers or sales credit note vouchers or free text invoice vouchers or free text credit note vouchers on the Accounts receivable parameters page, or number sequence codes that are used on the Journal names page for vouchers that have the Italian sales tax book field set to Sales. For a sales tax book of the Not included type: Select any suitable number sequence code.

Close Italian sales tax book section	Enter the closing date of the Italian sales tax book for a tax period. You can't post or reverse an invoice that has a date that's earlier than the closing date. This field is updated with the closing date of the tax period. The Update check box must also be selected on the Sales tax payment page.

The following button is also available.

Button	Description
Create	Automatically creates all the required sales tax book sections for existing sales tax books of the Sales and Purchase types. The process creates sales tax book sections for every number sequence that's defined for purchase invoice vouchers or purchase credit note vouchers or sales invoice vouchers or sales credit note vouchers or free text invoice vouchers or free text credit note vouchers on the Accounts payable parameters, Accounts receivable parameters, or Project management and accounting parameters page. It also creates sales tax book sections for every number sequence that's used on the Journal names page for vouchers that have the Italian sales tax book field set to Purchase or Sales. The process automatically attaches each created sales tax book section to the default sales tax book. (You must create the sales tax book before creating the sales tax book sections.) If several sales tax books of the same sales tax book type (Sales or Purchase) exist, the process uses the first sales tax book by default. However, you can manually change this attachment. If no sales tax book exists, the process doesn't automatically create sales tax book sections.

Using sales tax books

When you complete the setup, the sales tax book section that corresponds to the appropriate number sequence code appears in the Sales tax book section column on the Number sequences tab of the following pages:

Accounts receivable parameters
Accounts payable parameters
Project management and accounting parameters

You must assign voucher numbers during posting in sequential order by posting date. You must post sales tax transactions that use the same number sequence code in order. If the voucher numbers aren't sequentially ordered, you receive an error message. Additionally, posting is interrupted if a sales tax transaction isn't assigned to a sales tax book section when you update an invoice. When you post a voucher through a sales tax book section, the identifiers of the related sales tax book and sales tax book section are saved in the tax transactions. (Go to Tax > Sales tax inquiries > Posted sales tax, and then select the Posting tab.) You can use this data during further sales tax reporting. Italian sales tax books are used for filtering, grouping, and sorting on the Sales Tax (Italy) report.
