The Shopify POS app applies taxes based on the store location that you assign to your POS device. Store locations must be included in your shipping zones for taxes to be calculated correctly.
After your tax settings are configured, you can adjust the taxes that are applied to individual orders or products during a transaction from the Shopify POS cart.
The Shopify POS app applies taxes based on the store location that you assign to your POS device.
Steps:
Make sure that the new location is included in your shipping zones so that taxes can be calculated correctly. You need to do this step even if you never ship your products (for example, if you're only running Shopify POS).
From your Shopify admin, go to Settings > Taxes and duties.
In Manage sales tax collection, select the country/region your POS is located in.
In the Tax rates section, click the tax region and set the tax rate, then click Save:
If you're in the United States, choose automatic tax settings or manually specify the rates for state, county, and municipal taxes, including shipping taxes. You can also activate a tax service like Shopify Tax.
If you're not in the United States, use the default values or manually specify the rates for countries and their regions. You also specify whether you will charge taxes on shipping.
Assign your Shopify POS device to the new location. If the new location isn't shown, then background the app by pressing the home button on your device. Open the Shopify POS app again, and your new location should be available.
