# Block payments from tax-unsupported countries using Radar

If you use [Managed Payments](https://docs.stripe.com/payments/managed-payments), Stripe assumes indirect tax liability (VAT, GST, and sales tax) on your behalf in more than 80 countries. In countries not covered, you remain responsible for  tax compliance.
We recommend using [Stripe Tax](https://docs.stripe.com/tax) to manage compliance in unsupported countries at no additional Stripe Tax calculation fee.
If you prefer to not accept payments from those countries at all, you can explore [Radar](https://docs.stripe.com/radar) as an alternative to block them.
## Use Stripe Tax for unsupported countries
You can use Stripe Tax to manage compliance in countries not covered by Managed Payments. There is **no additional Stripe Tax calculation fee** on Managed Payments transactions where you handle tax yourself.
Visit [Stripe Tax for unsupported countries](https://docs.stripe.com/payments/managed-payments/tax-compliance#use-stripe-tax-for-unsupported-countries) to learn more.
## Block payments from unsupported countries with Radar
If you specifically need to prevent payments from customers in countries where tax compliance is unsupported, **Radar** can help you automatically block them based on one or more [supported attributes](https://docs.stripe.com/radar/rules/supported-attributes).
Custom rules require an upgrade to [Radar for Fraud Teams](https://stripe.com/radar/pricing).
### Block rule example
Because Managed Payments always collects billing addresses at checkout — it's required for tax calculation — the `billing_address_country` attribute is reliably available for every Managed Payments transaction.
`billing_address_country` reflects the billing address declared by the customer at checkout — it is not independently verified.
To block payments from all unsupported countries, you might consider adding a [block rule](https://docs.stripe.com/radar/rules) in your [Radar rules settings](https://dashboard.stripe.com//radar/rules) like the following:
```
block if :billing_address_country: not in ('AT', 'AU', 'BE', ...)
```
Replace the country list with the full set of [supported countries](https://docs.stripe.com/payments/managed-payments/tax-compliance#cross-border-sales). This approach means you only need to update the rule when new countries are added to the supported list.
**EU Geo-blocking Regulation:** If your business is based in the EU, you may
be subject to the Geo-blocking Regulation, which restricts blocking payments
solely based on a customer's location within the EU. Consult your legal advisor
before applying this rule to EU countries.
