Enabling Tax Support

In order to charge tax, you need to enable Tax Support. To do this, go to Setup > Payments > Tax Configuration, set the Tax Support toggle at the top of the page, and click Save Changes. This enables tax support in WHMCS and you can continue with further tax configuration.

General Tax Settings

Tax/VAT ID Number

Enter your company Tax/VAT ID in this field. Invoices will display this under the company address in the client area and on PDF printable invoices.

Inclusive/Exclusive Tax

By default, tax is exclusive. You need to add tax onto the prices you enter in WHMCS at the rate you entered. The alternative is inclusive tax, in which the prices you enter in WHMCS already include tax. For inclusive tax, WHMCS needs to work backwards to calculate the amount of tax to charge based on the rates you've set. You can choose the tax method you want to use in Setup > Payments > Tax Configuration.

• Exclusive Tax > Tax Amount = Item Price x ( Tax Rate / 100 )
• Inclusive Tax > Tax Amount = ( Item Price / ( 100 + Tax Rate ) ) x Tax Rate

Custom Invoice Numbering

To enable Custom Invoice Numbering, toggle the appropriate switch on the Tax Configuration page and click Save Changes. After you enable it, the configured custom invoice numbering will apply to invoices that you generate from then on.

Custom Invoice Numbering Format

This is the format of the custom invoice number to apply to the invoices WHMCS generates. The default value of this is `{NUMBER}`, which will contain only the value from Next Invoice Number. The field can contain any text in the invoice number that the client will see. You can add more tags to the field, which the system will replace when it generates the invoice.

Available tags are:

• {NUMBER} — The value of the Next Invoice Number field.
• {YEAR} — The four-digit year value for the current date.
• {MONTH} — The two-digit month value for the current date.
• {DAY} — The two-digit day value for the current date.

Next Invoice Number

The number that the system will assign to the next invoice it generates.

Auto Reset Numbering

This allows you to automatically reset the invoice number periodically. The automatic invoice numbering reset occurs when the automation cron runs on the last day of the month or year. If you want to use this feature, we recommend that you configure the cron job to run late at night in Setup > Automation Settings.

VAT Settings

Enabling VAT Mode

Toggle the "Enable VAT Mode" switch on the VAT Settings tab of Tax Configuration. This will automatically save and open a modal to set up your VAT rules for the EU.

Auto Configure VAT Tax Rules

If you accidentally delete, need to recreate, or change the name of a rule, use this to do this, using the appropriate VAT Rate for each EU country.

Custom Field Migration

If a WHMCS installation previously used the EU VAT Addon and a custom field to contain the client VAT Number, this option will display to perform a migration of the tax numbers from the custom field to store them in the client table.

Additional Settings

You can configure more settings, including validating the tax number and setting the client as tax exempt.

Tax Rules

You must configure Tax Rules in order to automatically charge tax in the cart. You can view and add Tax Rules from the Tax Rules tab of the Tax Configuration page.

Adding a Rule

To add a rule:

• In the Name field, enter a name for the tax zone, which allows you to identify it.
• For the Country, choose whether this tax rate applies to all countries or only applies to a selected country.
• For the state, choose whether it applies to all states in the selected country or only a selected state.
• Finally, enter the tax rate as a percentage (for example, 17.5).
• Click the Add Rule button. The system will create the tax rule and automatically add it to the appropriate table for Level 1 or Level 2 rules.

For example, a UK business would set up the system to charge VAT. In the country field, you would choose "United Kingdom" and for the state you would choose "Apply Rule to All States". You would then enter the tax rate of "20.0" and click the Add Rule button. You can set up an unlimited number of tax rules.

Advanced Rules

Setting Taxed Items

The flexible tax system in WHMCS allows you to set, individually, which items apply for tax. WHMCS sets products as untaxed by default. Even if you have tax rules set up, the system won't charge tax for it. This allows you to, for example, charge tax on the products you offer but not on services.

Setting a Product/Service as Taxable

To do this:

1. Go to Setup > Products/Services > Products/Services.
2. Click the edit icon next to the product you wish to set to be taxable.
3. Check the checkbox next to the item labelled "Tax Product".
4. Save your changes to the product.

Setting Domains as Taxable

You can set whether to apply taxes to domains in Setup > Payments > Tax Configuration. Use the checkbox in the Advanced Settings tab for this.

Setting Billable Items as Taxable

You can set whether to apply tax to billable items in Setup > Payments > Tax Configuration. Use the checkbox in the Advanced Settings tab for this.

Setting Late Fees as Taxable

You can set whether to apply tax to late fees on invoices in Setup > Payments > Tax Configuration. Use the checkbox in the Advanced Settings tab for this.

Setting Custom Invoices as Taxable

You can set whether to apply tax to custom (manually created) invoices in Setup > Payments > Tax Configuration. Use the checkbox in the Advanced Settings tab for this.

Compound Tax

The system calculates compound tax after and on top of a primary tax. If you need to add the Level 2 tax to the Level 1 tax, toggle this option on the advanced tab.

Deduct Tax Amount

If the Tax Type is Inclusive and the client's country and State or Province selections result in them not meeting any of the configured tax rules, deduct an amount from the order. Base this on the total amount for taxable items on the order and the percentage of tax that would apply to the default country in the Setup > General Settings > Localisation tab. It will deduct the percentage that applies to the first applicable Level 1 and Level 2 tax rules.

Tax Calculation Mode

The Calculation Mode setting determines how the system calculates taxes.

There are two possible values for this setting:

• Calculate individually per line item — Selecting this option will calculate taxes on a per line item basis. When you select this, the system will calculate tax for each line item, rounded to 2 decimal places. It will also calculate the total tax using the sum of the tax calculation for each individual line item.
  Example Tax Calculation for 4 Line Items of $1 each: (1.00 x 20%) + (1.00 x 20%) + (1.00 x 20%) + (1.00 x 20%) = 0.80
• Calculate based on collective sum of the taxable line items — Selecting this option will calculate taxes using the sum of the taxable line items on an invoice. When you select this, the system totals the individual taxable line items and calculates tax based on the sum total of those taxable line items.
  Example Tax Calculation for 4 Line Items of $1 each: (4.00 x 20%) = 0.80
