Configure Taxes

··

Last updated on Aug 27, 2026

Advanced Billing offers three ways to charge tax, and they differ in how precisely they calculate and how much setup they need. Use this guide to pick the method that fits how your company handles tax, configure the origin and destination addresses every method depends on, then complete the setup specific to the method you chose.

Choose a tax method

Pick one method before configuring anything. Switching later is possible, but enabling Managed Sales Tax disables any custom taxes you already set up.

Tax methods and when to use each

MethodReasons to use
Custom TaxesFor simple sales tax. Taxes down to the state or region level.
Managed Sales TaxThe most common choice. No code and a quick launch, taxing down to a specific jurisdiction such as state plus county. Powered by Advanced Billing's own integration to Avalara.
Avalara IntegrationFor companies that want to connect their own Avalara account. Requires an existing Avalara account.

1. Configure your tax addresses

Every method needs to know where you are and where your customer is, because tax depends on both. Set both addresses once, and they apply whichever method you go on to configure.

Add the tax origin address

The tax origin address is where your business is located.

The Tax Origin Address dialog
FieldDescription
Address(Required) Line 1 of your company's tax origin address.
Address Line 2Line 2 of your company's tax origin address.
City(Required) City of your company's tax origin address.
Country(Required) Country of your company's tax origin address.
State(Required) State of your company's tax origin address. If your country has no states, this populates as no state.
Zip Code(Required) Zip code of your company's tax origin address.

Set the tax destination address

The tax destination address is the customer address Advanced Billing taxes against. Choose which of the customer's addresses decides it.

2. Configure your chosen method

With both addresses in place, complete the setup for the one method you picked. Follow only the section that matches it.

Set up custom taxes

Custom taxes are rules you write yourself, each pairing a country and state with a rate.

On the Taxes settings page, click + Create New Tax.

Then complete the form.

a Create New Tax form: name, tax type as general or EU VAT, and a rule with country, state and rate
The Create New Tax form
FieldDescription
Name(Required) Name of the custom tax. This displays on the invoice where applicable.
Tax Type(Required) Which kind of tax this is.
  • General Tax - For most use cases, such as US sales taxes.
  • EU VAT Tax - Only available to EU customers, who can opt out by supplying a valid VAT number.
Country(Required) The country the tax rule applies to.
State(Required) The state the tax rule applies to. If the country has no states, this populates as no state.
Rate(Required) The percentage amount of the tax, between 1 and 100.
+ Add another Tax RuleAdds another rule to the tax. Fill out the Country, State, and Rate fields again for each rule.

Set up managed sales tax

Managed Sales Tax hands calculation to Avalara through Advanced Billing's own integration, so you don't supply rates yourself. Instead you tell Advanced Billing which regions you're liable in.

WARNING: Enabling Managed Sales Tax disables any existing custom taxes. If you already configured custom taxes, check the tax included in price option on your price points afterward to reconfigure existing product and component taxes.

On the Taxes page, click Enable Advanced Billing Taxes.

Confirm your tax origin address when prompted. This is the same address described in step 1, and Managed Sales Tax requires a full, valid one.

Finally, set your taxable regions.

The Taxable Regions dialog

Important: Customers outside your taxable regions are not taxed at all. Taxable regions are the jurisdictions you declare yourself liable in, so anything you leave unset produces untaxed invoices rather than an error.

Set up the Avalara integration

This method connects your own Avalara account rather than using Advanced Billing's.

On the Taxes page, click Get Started in the Link My Avalara Account panel.

Get Started, in the Link My Avalara Account panel

Then supply your Avalara credentials.

a Connecting your Avalara Account dialog with Avalara account ID and license key fields
The Connecting your Avalara Account dialog
FieldDescription
Avalara Account ID(Required) The account ID for your Avalara account.
Avalara License Key(Required) The license key for your Avalara account.

To show a tax breakdown, such as an EU VAT or UK VAT breakdown, on the invoices these taxes appear on, see the Configure Invoices help article.
