# Construction Withholding Tax

#### What is CWT?

In Germany, the **Construction Withholding Tax** is a tax regulation applied on construction services where the contractor (customer) withholds 15% of the subcontractor’s (vendor) invoice amount and pays it directly to the German tax authorities. The withheld amount is credited for the contractor’s tax liability, and they can use it to reduce their tax bills.

#### Who Should Register for CWT?

If you’re a contractor involved in a construction business in Germany, it is mandatory that you register for CWT. It is not compulsory for subcontractors to be registered for CWT, but if you are not registered, the tax amount will be deducted from your payments at a higher rate.

### Enable CWT in Zoho Books

**Warning:** You cannot disable CWT in your organisation after you create a transaction under it. You can disable it only after you delete all transactions under CWT.

You can enable CWT to deduct money for services covered under it in transactions. Here’s how:

*   Click **Settings** on the top right corner of the page.
*   Click **Taxes** under _Taxes & Compliance_.
*   In the _Taxes_ pane, click **Construction Withholding Tax**.
*   Select **Yes** if you want to track CWT under **Do you want to track CWT on transactions?**
*   In the **CWT Role** dropdown, select _Contractor_ if your organization hires other businesses for construction work, _Subcontractor_ if you perform construction work for a contractor, or _Both_ if you act as both a contractor and subcontractor.
*   If you are a subcontractor, select the **CWT Deduction Rate** (Percentage of invoice amount deducted by the contractor) from the dropdown.
*   Click **Save**.

*   Click the **Customers** module under **Sales** on the left sidebar.
*   Click **+New** button on the top-right corner to [create a new customer](https://www.zoho.com/en-de/books/help/contacts/#create).

### CWT in Transactions

**Prerequisite:** You should enable CWT tracking for your customer or vendor if you want to create transactions under CWT for them.

**Note:** CWT is not supported in _Retainer Invoices,_ _Expenses_ and _Recurring Expenses_.

#### CWT in Sales Transactions

When you send an invoice to your contractor, you can choose services which come under CWT. Here’s how:

*   Create a [new invoice](https://www.zoho.com/en-de/books/help/invoice/#create-invoice).
*   After filling in the necessary details, check the **Covered by CWT?** checkbox if a service comes under CWT.

Zoho Books will automatically calculate the deductions using the CWT Deduction rate which you provided in the [CWT Settings](/en-de/books/help/cwt/cwt.html#Enable-CWT-in-Zoho-Books) for the services you choose.

#### CWT in Purchase Transactions

When you send a bill to your subcontractor, you can choose the services for which you deduct the amount on their behalf. Here’s how:

*   Create a [new bill](https://www.zoho.com/en-de/books/help/bills/basic-functions.html#create-bill).
*   After filling in the necessary details, check the **Covered by CWT?** checkbox if a service comes under CWT.

Zoho Books will automatically calculate the deductions using the CWT Deduction rate that you provided when adding a subcontractor as a vendor for the services you choose.
