You can create a TCS rate and set an applicable period for that TCS rate such that they are valid only for that particular period. To create a TCS rate with an applicable period: * Go to _Sales_ on the left sidebar and select **Invoices**. * Click **\+ New** to create a new invoice, or select the invoice to which you want to apply TCS rate and click **Edit**. * Enter all the necessary details and scroll down to the _Total_ section. * Choose **TCS** and click **Manage TCS** from the _Select a Tax_ dropdown. ![Manage TCS](/in/books/kb/images/taxes/click-manage-tcs.png) * Click **\+ New TCS Tax** in the pop-up window. ![New TCS](/in/books/kb/images/taxes/new-tcs-tax.png) * Enter _Tax Name_, _Rate_, and select the _Nature of Collection._ * Mark the _This is a Higher TCS Rate_ checkbox, if you’re adding a higher TCS rate and select a reason for it in the _Reason for Higher TCS Rate_ dropdown. * Select a _Start Date_ and an _End Date_ for TCS rate under _Applicable Period_. ![Manage TCS](/in/books/kb/images/taxes/manage-tcs-rate.png) * Click **Save** and the period will be created. Once the applicable period ends, the status of the TCS Rate will be _Expired_. ![Manage TCS](/in/books/kb/images/taxes/tcs-expired.png) ### Edit the Applicable Period of a TCS Rate **Warning:** If you edit other fields apart from the Start Date and End Date, a new TCS rate will be created. To edit the applicable period of a TCS rate: * Go to _Sales_ on the left sidebar and navigate to **Invoices**. * Select the invoice that you want to edit and click **Edit** on the top bar. * Scroll down to the total section and click **Manage TCS** from the dropdown next to TCS. * Hover through the TCS rates and click the **Edit** icon in its row. ![Edit TCS](/in/books/kb/images/taxes/edit-tcs-rate.png) * Change the **Start Date** or the **End Date** according to your preference. **Insight:** Similarly, you will be able to create and apply them while recording your bills in Zoho Books. The TCS rate will be saved with the start date and end date you’ve selected. **Note:** Once a TCS rate has been applied to a transaction within its applicable period, you cannot edit the start date or the end date such that the transaction date is not within the applicable period.
