+
+This module provides you with the Tax Statement in the Dutch format.
+
+The Tax Statement can be generated in two ways, according to
+the chosen Dutch accounting system:
+
+* Kasstelsel
+* Factuurstelsel
+
+By default the Tax Statement is generated according to the *Factuurstelsel* system.
+It means that, when validating an invoice, the system uses the invoice date instead of accounting date to determine the date of the move line for tax lines.
+See https://www.belastingdienst.nl/wps/wcm/connect/bldcontentnl/belastingdienst/zakelijk/btw/btw_aangifte_doen_en_betalen/bereken_het_bedrag/hoe_berekent_u_het_btw_bedrag/factuurstelsel
+
+About the *Kasstelsel* system instead, more information can be found
+in: https://www.belastingdienst.nl/wps/wcm/connect/bldcontentnl/belastingdienst/zakelijk/btw/btw_aangifte_doen_en_betalen/bereken_het_bedrag/hoe_berekent_u_het_btw_bedrag/kasstelsel/kasstelsel

+
+Configuration
+=============
+
+This module makes use of the tax tags (eg.: 1a, 1b, 1c, 1d, 2a...) as prescribed by the Dutch tax laws.
+
+If the default Odoo Dutch chart of accounts is installed (module ``l10n_nl``) then these tags are automatically present in the database.
+
+If a non-standard chart of accounts is installed, you have to manually create the tax tags and properly set them into the tax definition.
+The name of the tags must be formatted this way: "+1a (omzet)", "+1a (btw)", "-1a (omzet)", "-1a (btw)", "+2a (omzet)", "+2a (btw)", etc...
+
+This module provides an accounting setting *Invoice basis* (Factuurstelsel)
+that is enabled by default. This option makes the *invoice date* leading for
+the tax declaration of a period, rather than the accounting date, and
+allows you to change the accounting date of incoming invoices to the period
+to which the costs apply and still create a legally valid Dutch tax
+declaration. Without this option, the entries on the tax statement are
+collected using only their accounting dates (what Odoo calls *standard
+taxes*).
+
+This setting is not compatible with the Odoo *Cash basis* (Kasstelsel) setting
+which leads to the creation of tax journal lines at the moment that a payment
+is received, so when using *Cash basis* you need to disable the *Invoice
+basis* setting to create a valid Dutch tax declaration using this module.
+To disable the *Invoice basis* for a company, you need to:
+
+#. Open your Company form and verify that Country is set to ``Netherlands``.
+#. Go to ``Invoicing -> Configuration -> Settings``, enable/disable ``NL Tax Invoice Basis (Factuurstelsel)`` and ``Apply``.
+
+Usage
+=====
+
+To create a statement you need to:
+
+#. Verify that you have enough permits. You need to belong at least to the *Billing Manager* or the *Accountant* group.
+#. Go to the menu: `Invoicing -> Reporting > NL BTW Statement`
+#. Create a statement, providing a name and specifying start date and end date
+#. Press the Update button to calculate the report: the report lines will be displayed in the tab `Statement`
+#. Manually enter the BTW amounts of lines '5d', '5e', '5f' (in Edit mode, click on the amount of the line to be able to change it)
+#. Press the Post button to set the status of the statement to Posted; the statements set to this state cannot be modified
+
+To add past undeclared invoices/moves:
+
+#. Open the tab `Past Undeclared Moves`, available when the statement is in status Draft.
+#. Set an initial date (field From Date) from which the past undeclared moves will be displayed.
+#. One by one, add the displayed undeclared moves, by clicking on the `Add Move` button present in each line.
+#. Press the Update button in order to recompute the statement lines.
+
+Extra info about the workflow:
+
+#. If you need to recalculate or modify or delete a statement already set to Posted status you need first to set it back to Draft status: press the button Reset to Draft
+#. Instead, if you send the statement to the Tax Authority, you may want to avoid that the statement is set back to Draft: to avoid this, press the button Final. If you then confirm, it will be not possible to modify this Statement or reset it back to draft anymore.
+
+Printing a PDF report:
+
+#. If you need to print the report in PDF, open a statement form and click: `Print -> NL Tax Statement`
+
+Multicompany fiscal unit:
+
+#. According the Dutch Tax Authority, for all the companies belonging to a
+   fiscal unit, it's possible to declare one single tax statement.
+#. To create one tax statement for a fiscal unit, log in into the parent
+   company and select the child companies in the statement (be sure the user
+   belongs to the multicompany group).
+#. The child companies must have the same Tax codes labels (Tax Tags) as the
+   parent company, the same currency as the parent company and must be located
+   in The Netherlands.
+
+Known issues / Roadmap
+======================
+
+* Exporting in SBR/XBLR format not yet available
+* Limit invoices to last 5 year based on fiscal year end date (legal requirement)
+* The unreported from date is calculate as 1 quarter, it should take 1 fiscal year based on fiscal year end date
