# Add a Tax Rate
CrewCost allows you to configure sales tax rates under the Accounting module. Tax rates can be defined as Single (one rate tied to one agency) or Combined (multiple rates grouped under one name). Once created, these rates are available for use across your accounting workflows.
### Access the Sales Tax Section
Navigate to the Sales Tax rates list to begin creating a new rate.
1. In the left sidebar, click **Accounting** to expand the menu.
2. Click **Sales Tax**.
3. Select the **Rates** tab at the top of the page.
4. Click the **+ New Rate** button in the upper-right corner of the rates list.
### Configure a Single Tax Rate
The New Tax Rate panel will open on the right side of the screen. Follow the steps below to set up a single rate.
1. Under **Type**, select **Single**.
2. In the **Name** field, enter a name for the rate.
3. Click the **Agency** dropdown and select an existing agency from the list. If no agency exists yet, select **Add an agency** to create one.
4. In the **Tax Rate (%)** field, enter the percentage value for the rate (for example, `8.555`).
5. Click **Save** to create the rate or **Cancel** to discard the changes.
### Configure a Combined Tax Rate
A Combined rate groups two or more existing single rates under one name. The panel displays a Total tax **rate** counter that updates as rates are selected.
1. Under **Type**, select **Combined**.
2. In the **Name** field, enter a name for the combined rate.
3. Under **Rate 1**, click the **Select rate** dropdown and choose an existing single rate.
4. Under **Rate 2**, click the **Select rate** dropdown and choose a second existing single rate.
5. To include additional rates, click **+ Add** and select the corresponding rate from the new dropdown that appears.
6. Click **Save** to create the combined rate, or **Cancel** to discard the changes.
Once saved, the new rate will appear in the **Rates** list under **Accounting > Sales Tax**, displaying its name, associated agency, type, and percentage.
