I can guide you through the steps in entering TDS (Tax Deducted at Source) in your QuickBooks Online (QBO) account. Let’s enable your TDS so you can make an entry for your client. Here’s how:
Go to the Sales or Invoicing menu.
Select Customers at the top.
Click on the name of the customer for whom you want to enable TDS and click Edit.
In the customer information pop up, click on the Tax info tab and enter the PAN number and check the TDS Applicable checkbox.
Then click Save.
Once done, you’ll get an option to select the TDS section and enter the amount applicable when creating an invoice.
