+CIS deduction
+=============
+
+The Construction Industry Scheme deduction (CIS deduction) is a tax deduction system used in the UK
+designed specifically for the construction industry. It requires contractors to deduct a percentage
+of payments made to subcontractors and forward these deductions to HM Revenue and Customs (HMRC).
+These deductions apply only to the labor portion of the payments and serve as advance payments
+towards the subcontractor's tax and National Insurance contributions. Contractors are required to
+register for the scheme, but subcontractors are not. However, subcontractors who are not registered
+face higher payment deductions. Under the |CIS|, contractors must deduct 20% from payments to
+registered subcontractors, while the deduction increases to 30% for unregistered ones.

+   - `Guidelines for CIS subcontractors
+     <https://www.gov.uk/what-you-must-do-as-a-cis-subcontractor>`_
+
+As a contractor, you are required to register with the |CIS| before hiring subcontractors and to
+check whether each subcontractor is registered with the |CIS|. You must also maintain records of all
+payments and deductions and submit monthly returns to HMRC, including the following details:
+
+- information about the subcontractors
+- records of payments made and any deductions applied
+- a declaration confirming that the employment status of all subcontractors has been reviewed
+- a declaration confirming that all subcontractors requiring verification have been verified
+
+.. note::
+   If no payments were made to subcontractors in the previous tax month, contractors must notify
+   |HMRC| by the 19th of the month to avoid a penalty.
+
+To submit Monthly Returns to |HMRC|, :ref:`install <general/install>` the
+:ref:`UK - Construction Industry Scheme <localization/united-kingdom/modules>` module.
+
+.. tip::
+   To enable the :guilabel:`Test` mode and use test credentials, open the Settings app, activate the

+To configure your company's |HMRC| information, go to the Settings app and, in the
+:guilabel:`Companies` section, click :guilabel:`Update Info`. Open the :guilabel:`HMRC` tab and

+|CIS|-related fields are displayed.
+
+By default, the :guilabel:`Deduction rate` is set to 30%. To modify it, first enter the
+:guilabel:`Verification Number` provided by |HMRC| when verifying the subcontractor's status, then
+update the :guilabel:`Deduction Rate` accordingly.

+
+The appropriate |CIS| tax must be applied to **labor items** on vendor bills based on the
+subcontractor's :guilabel:`Deduction Rate`: :guilabel:`0% CIS`, :guilabel:`20% CIS` or
+:guilabel:`30% CIS`. To apply the rate, go to the :guilabel:`Invoice Lines` section of the vendor
+bill and select the appropriate |CIS| tax rate in the :guilabel:`Taxes` column of the **labor**
+items.
+
+.. note::
+   - The |CIS| tax rate is not necessary for material items on vendor bills.

+Monthly returns sending
+~~~~~~~~~~~~~~~~~~~~~~~
+
+On the 6th of each month, Odoo sends a reminder email to submit a monthly return to |HMRC|. The
+recipient email address is the one entered in the company :guilabel:`Email` field. To send monthly
+returns to |HMRC|, go to :menuselection:`Accounting --> Reporting --> Tax Return` and follow these
+steps:
+
+#. Click :icon:`fa-book` :guilabel:`Report:` and select :guilabel:`CIS Deduction (GB)`.
+#. In the :icon:`fa-calendar` :guilabel:`(calendar)` date selector, the :guilabel:`Tax Period` is
+   automatically adjusted to match the |CIS| deduction period.
+#. Click on :guilabel:`Send to HMRC` in the top-left corner.
+#. In the :guilabel:`CIS monthly return` window, select the required options in the
+   :guilabel:`Declaration` section:
+
+   - :guilabel:`Employment Status`: To declare that the employment status of all subcontractors has
+     been reviewed.
+   - :guilabel:`Subcontractor Verification`: To declare that all submitted subcontractors requiring
+     verification have been verified.
+   - :guilabel:`Inactivity Indicator`: To declare temporary inactivity.
+
+#. In the :guilabel:`Information correct declaration` section, confirm the information is true and
+   complete by checking the box. Then, enter the :guilabel:`Password` used in the
+   :guilabel:`HMRC Credentials` section during
+   :ref:`contractor setup <localization/united-kingdom/cis-contractor-setup>`.
+#. Click :guilabel:`Send` to prompt Odoo to request |HMRC| to initiate the transaction.
+
+When |HMRC| replies to a transaction, Odoo automatically notifies the user who submitted it by
+email. The email informs them that the response is available in the company's chatter with an
+attached XML document for download. Both the electronic and paper versions of the |HMRC| receipt
+should be retained. If an error is detected, a new submission is required to comply with |HMRC|
+requirements.
+
+.. note::
+   - Transactions are updated daily. To manually update the |HMRC| request, click the :icon:`fa-cog`
+     :guilabel:`(gear)` icon and select :guilabel:`Refresh HMRC request`.
+   - |CIS| invoices are included in the :guilabel:`CIS Deduction (GB)` report but are not sent to
+     |HMRC|.
