How do I automatically update the tax rates for the items in Zoho Books?

You can update to new GST rates from the GST Slabs Redefined banner in your organisation’s Home Page. To do so:

Go to your Zoho Books organisation’s Home page.
Click View Details from the GST Slabs Redefined banner.
Click Review Updates to apply the new tax rates automatically.
Review the tax changes and click Proceed to Schedule Update.
If your organisation has more than 250 items, the preview will not be available.
- You can download the Tax Update file from the generated link to view the new tax rates for all items, along with their HSN Codes, Composite Items, and Recurring Transactions.
Once you have reviewed the items and tax rates, click Confirm & Schedule.
Select your preferred date for updating the tax rates.
