Taxes
Taxes are an integral part of any business. The taxes applicable to your business are determined by your business’s location and type. In Zoho Books, there are country specific taxes, multiple tax rates, and tax groups that you can configure according to your business’s needs.
Enable GST
If you didn’t enable GST when setting up Zoho Books, you can enable it later. To enable:
- Go to Settings.
- Select Taxes under Taxes and Compliance.
- Hover over Is your business registered for GST? and toggle it to Yes, and complete the following fields:

- GST Registration Number: Enter your 10-digit GST number.
- Reporting Period: Choose Monthly, Quarterly, or Yearly.
- Tax Basis: Select Accrual if you report income and expenses when they happen, or Cash if you report them when money is received or paid.
- Tax Return Start Date: Select the start date for your reporting period based on your organisation’s fiscal year. Your first tax return will be generated from this date.

GST will now be enabled for your organisation.

How Tax Rates Are Auto-Applied to Items in a Transaction
A tax rate is automatically assigned to an item in a transaction based on three key details:
- Item’s Tax Category: When you create an item, you select its tax category (e.g., electronics, hardware, services). Based on the selected tax category, the GST rate that’s applicable to the item is determined.
- Customer’s GST Eligibility: When you create a customer, you mark them as GST-eligible and enter the GST Registration Number. This helps determine whether GST should be charged and how it should be handled.
- Customer’s Country/Region in Billing Address: You select the customer’s country or region in the billing address. This helps identify whether the transaction is local or overseas and ensures the correct GST rate is applied (e.g., 0%, 8%, 9%, or tax-exempt)
Based on these details, the correct GST rate is automatically applied to each item in a transaction.
Other Important Considerations on How the Tax Rate Is Applied Based On Tax Categories
- Local customers pay 9% GST for standard-rated supplies in tax categories like Default Product, Electronics, Hardware, Telecommunication Services, and Professional Services.
- Tax categories like Financial services and the import or local supply of Investment Precious Metals (IPM) are exempt from GST.
- Overseas customers are charged 0% GST for exports across all tax categories.
- Singapore-registered customers who buy Prescribed Goods (such as Blackberry devices, memory sticks, tablets, and smartphones) with a sale value over $10,000 must pay 9% GST under Customer Accounting.
