Adding your tax registration numbers ensures your business complies with government regulations and helps your clients identify your registered status.

In this detailed guide, we’ll walk through everything you need to know about adding tax registration numbers in Zoho Invoice:  including what they are, why they matter, how to set them up, how to customize where they appear, and how to ensure they display correctly on your invoices and other forms.

Understanding Tax Registration Numbers

Before learning how to add tax registration numbers in Zoho Invoice, it’s important to understand what they are and why they are essential for your business.

A tax registration number (often called a Tax ID, VAT number, GSTIN, or Sales Tax ID, depending on your region) is a unique identifier assigned to your business by your country’s tax authority. This number allows the government to track your business’s tax responsibilities, such as collecting and remitting sales taxes or value-added taxes.

For example:

• In India, businesses registered under the Goods and Services Tax system are given a GSTIN (Goods and Services Tax Identification Number).
• In the United Kingdom and European Union, companies registered for Value Added Tax receive a VAT Registration Number.
• In the United States, businesses may display a Sales Tax ID or EIN (Employer Identification Number), depending on their operations.

Including these numbers on invoices and other tax documents ensures compliance and enhances the credibility of your business.

Why Adding Tax Registration Numbers in Zoho Invoice Is Important

In many countries, it is legally required for businesses to display their tax registration numbers on every invoice. Even where it isn’t mandatory, doing so still benefits your business. Here’s why:

1. Compliance: Ensures your invoices meet local tax authority regulations.
2. Professionalism: Customers perceive businesses with clear tax information as more legitimate and trustworthy.
3. Transparency: Clearly indicates your tax status to clients and auditors.
4. Simplified Accounting: When your tax details are automatically included on invoices, you reduce manual errors.
5. Tax Credits and Filings: Customers may need your registration number to claim tax credits or for bookkeeping purposes.

With Zoho Invoice, you can easily configure your tax registration details once, and the software will automatically display them on every applicable invoice and sales form.

Adding Your Tax Registration Number in Zoho Invoice

Zoho Invoice allows you to add tax details directly from your organization profile settings. The software supports different tax systems based on your country, and the field names may vary — for example, “GSTIN,” “VAT Number,” or “Tax ID.”

Step 1: Log in to Zoho Invoice

Go to the Zoho Invoice website and log in using your administrator credentials. You’ll need administrative access to modify tax settings.

Step 2: Access Organization Settings

Once logged in, click the gear icon (settings) usually located in the upper-right corner of the dashboard. From the settings menu, select Organization Profile or Company Profile depending on your version.

This section contains all your company’s key details such as business name, address, contact information, and tax registration data.

Step 3: Enter Tax Registration Information

Scroll down to the section labeled Tax Information or Business Identification. Depending on your country’s localization settings, you’ll see fields for entering your tax details.

For example:

• If your organization is set to India, you’ll see a field labeled GSTIN.
• For UK users, it will appear as VAT Registration Number.
• In other regions, it might simply appear as Tax ID or Business Number.

Enter your valid tax registration number exactly as it appears on your official documents. Double-check the format;  incorrect entries could cause compliance issues or invoice rejections.

Step 4: Save Your Changes

Once you’ve entered your tax registration number, scroll to the bottom and click Save or Update Organization Details.

Zoho Invoice will now store your tax number as part of your company’s profile, and it will automatically appear on your invoices and other relevant transaction forms.

Customizing How Tax Registration Numbers Appear on Invoices

After adding your tax registration number to your organization profile, you can control where and how it appears on your invoices. Zoho Invoice offers a customization feature that lets you edit the layout and design of your invoice templates.

Step 1: Go to Templates

From your Zoho Invoice dashboard, click on the Settings icon again, and this time select Templates. This section allows you to customize the appearance of different documents, such as invoices, estimates, and payment receipts.

Step 2: Choose an Invoice Template

Select the type of document you want to modify,  for example, Invoice. A list of available templates will appear. Choose your preferred template, then click Edit to open the customization interface.

Step 3: Edit Header or Footer Sections

The tax registration number can typically be placed in the header or footer of the invoice. Many businesses choose to display it near their company logo or address in the header for visibility.

Click on the Edit Header option, and locate the text area containing your company details. You can then add your tax registration number manually if it’s not already visible. For example:

“Registered Business Name: ABC Enterprises Pvt. Ltd.
GSTIN: 29ABCDE1234F1Z5”

Alternatively, you can include your tax number in the footer section, right below your thank-you note or business contact details. This positioning is often preferred for a cleaner design.

Step 4: Use Dynamic Fields (Optional)

Zoho Invoice also allows the use of dynamic or placeholder fields that automatically populate your tax registration number. This means you don’t have to type it on each template.

In the customization editor, look for the option to insert a field such as “Organization GSTIN” or “Company VAT Number.” When you add this field, Zoho will automatically display your stored tax registration number from the organization profile on every invoice.

Step 5: Preview and Save

Before finalizing, use the Preview option to see how your tax registration number appears on the invoice. Adjust the font, spacing, or placement if needed for readability and professional presentation. Once satisfied, click Save to finalize your template.

Displaying Tax Registration Numbers for Customers

In some regions, your customers may also have tax registration numbers that need to be displayed on invoices. Zoho Invoice allows you to store each customer’s tax details and include them automatically.

To do this:

1. Navigate to the Customers module.
2. Open the customer’s profile or click Edit if it already exists.
3. Scroll down to the section labeled Tax Information or Customer Tax Details.
4. Enter your customer’s VAT or GST number in the appropriate field.
5. Save the customer profile.

Now, when you create an invoice for that customer, Zoho Invoice will automatically include both your business’s and your customer’s tax registration numbers in the document.

Adding Multiple Tax Registration Numbers (for Multi-Branch Businesses)

If your business operates from multiple locations or has multiple tax registration numbers,  for example, separate GSTINs for different states in India.  Zoho Invoice allows you to manage them as separate entities. Each branch or location can have its own tax identification number under the same Zoho account.

Here’s how:

1. Go to Settings and select Organizations.
2. Click Add Organization to create a new branch profile.
3. Enter the details for that branch, including its specific tax registration number.
4. Save the organization profile.

When issuing invoices, you can choose which organization or branch is responsible for the transaction. The corresponding tax registration number will automatically appear on the form.

Ensuring Tax Numbers Display Correctly on PDF Invoices

After setting everything up, it’s important to confirm that your tax registration numbers are properly displayed on printed and PDF versions of your invoices.

1. Create a new test invoice using any customer profile.
2. Add a product or service, review the tax calculations, and save the invoice.
3. Click on Preview PDF or Download PDF.
4. Check the header or footer for your tax registration number.

If it doesn’t appear, go back to your template editor and ensure the tax registration field is included. Adjust the layout as needed, then preview again.

Adding tax registration numbers is not a one-time task,  it’s an ongoing compliance requirement. To make the most of Zoho Invoice’s features, follow these best practices:
