In VAT Books you generate the tax books and annexes from the registered sales and purchases. The screen shows only the books for the active branch’s country: in El Salvador, those required by the Ministry of Finance (Hacienda); in Guatemala, the sales and purchases books; in the United States, the Sales Tax report (the screen is titled Sales Tax Reports).

El Salvador

Book / Annex	Content
Final Consumer Sales Book	Final consumer invoices for the period.
Taxpayer Sales Book	Comprobantes de Crédito Fiscal (CCF, tax credit invoices) issued.
Purchases Book	Purchases with tax credit (purchases annex).
Purchases from Excluded Subjects	Facturas de Sujeto Excluido (excluded subject invoices).
Document Invalidations	Tax documents invalidated in the period.
1% VAT (IVA) Withholding	Withholdings made to the taxpayer.
1% VAT Perception	Perceptions made to the taxpayer.
2% VAT Advance Payment	Advance payments made to the taxpayer.

In the Purchases Book and the Taxpayer Sales Book, credit notes subtract, and debit notes and CCFs add. For credit and debit notes the total comes from the operation amount even when the document does not carry a “total to pay”.

Select the book and the period

Download

As Excel/CSV for upload to the Hacienda portal, or as PDF for filing.

You can also download all JSON files or all PDFs of the period’s electronic documents, as a backup.

Guatemala

Monthly books downloaded as PDF or Excel (there is no CSV). In both, voided documents appear with Voided status and no amounts, and credit notes subtract.

Book	Content
Sales Book	Sales and services provided in the month (output VAT). Columns: No., Date, Type, Series and number, Authorization, NIT, Customer, Status, Taxed goods, Taxed services, Exempt, Output VAT, and Total.
Purchases Book	Purchases and services acquired in the month (input VAT). Same columns, with Document, Supplier, and Input VAT.

The columns of the Guatemala books have not yet been validated against an official SAT specification; review them with your accountant before using them to file.

United States

The United States has no federal VAT book: what is filed is the period’s Sales Tax. The Sales Tax Report is monthly and is downloaded as PDF or Excel. It includes the Invoice, Credit Memo (subtracts), and Debit Memo (adds) documents processed in the month, excluding voided ones.

Section	Content
Sales overview	Gross sales, credit notes (returns), net sales, taxable sales, exempt and non-taxable sales, and Sales Tax collected.
Tax collected	For each tax: rate, taxable sales, and amount collected.
Detail	One row per document (date, document, number, customer, taxable and exempt sales), with one column per tax and the total.

The report does not break down by jurisdiction (county or city): the system does not yet store that information.

All the books are also accessible from the Reports Center.
